Highly degraded semi-arid regions could be potential crop production areas to meet the ever increasing food and beverages demands of the growing population. The major production challenges this region faces are water scarcity, soils and biodiversity loss due to prolonged drought, erosions and leaching. These make farmers to depend on supplementary irrigation and commercial fertilizers for crop production and the conditions are even worsened with change in climate. In the past, organic amendments and polymers such as polyacrylamides (PAM) were used to improve soil physiochemical properties and protect soils from erosion but to no avail. The aim of this paper was to review different scientific research findings on the potential value of Biochar in green house gas sequestration, and Soil Amendment in particular in sites under serious degradation. Many scientific findings (170) published in brochures; journals, abstract, and thesis on biochar potentials on soil nutrient cycling, green house gas sequestration, and soil/land rehabilitation with methodology that can be reproduced were reviewed and synthesized. We found out that Biochar has proven potentials to improve soil physical, biological and chemical properties hence boosting soil fertility and productivity and as well as sequester carbon dioxide from the atmosphere-biosphere pool and transferred it to soil. Biochar also remained a promising solution to energy. With good extension service packaging, biochar can be effectively adopted as solutions to soil degradation and pollution. Key words: Biochar, Carbon, Climate change mitigation, Green house gases (GHG) sequestration, Soil properties, .

Treatment lasted for eight weeks and results showed that explicit instruction and cognitive style have main significant effects on studentsβ achievement in summary writing. Based on the findings, it was concluded that the use of explicit and cognitive styles in language pedagogy have great potentials for improving achievement in summary writing. The strategy encouraged active participation of students through practice sessions and corrective feedback.
Background: The male reproductive aspect of mammals and lizards is essentially different on the bases of the morphology of their reproductive tract. The lizards are devoid of secretary glands. Even then they have the seminal plasma for the suspension of their sperms. However, in addition to semen plasma, smooth musculature of vas deferens (VD) also helps in providing the driving force for the propulsion of sperm along with their own motility. Apart from differences in reproductive cycle and seasonal effects on lizardβs reproduction in comparison to mammals, it seems that there is a probable difference in the physiological and pharmacological properties of the smooth muscles of their VD as well. Objectives: Therefore, the present study was designed to compare the physiological and pharmacological responses on receptors of VD against acetylcholine (ACh), adrenaline (Adr) and their antagonists in Uromastix (lizard), and Rabbit (mammal). Methodology: Freshly isolated muscle strips of Uromastix hardwickii & Rabbit Oryctologous cunniculus were mounted on organ bath assembly and their physiological (mechanical) activity was continuously monitored by adding different pharmacological agonists and antagonists on data acquisition system, Power-lab. Results: Results demonstrated that in Uromastix hardwickii the basal tone of VD was decreased by the administration of both the acetylcholine (Ach)&adrenaline (Adr) without the appearance of rhythmicity and their actions were significantly antagonized by Atropine (Atr) and Atenolol (Ate), respectively. While, the basal tone in Rabbit VD was increased by both the ACh & Adr, which later followed by the appearance of spontaneous rhythmic contraction. This preliminary study on the smooth muscles of VD in Uromastix highlights the differences in the physiological activity and the presence of adrenergic and cholinergic receptors

This paper takes a look at language norms with the major principal variables that control it. The concept of language code and its pedagogies in teaching English language from unset is examined. Language construct is highlighted in teaching pedagogy. Also, the language convention is considered along with classroom interactions.The linguistic norm is one of the essential characteristics of a language, ensuring its functioning and historical continuity as tacit agreements in society and an acceptable standard that users of a language are expected to reach. It is believed that norms guide and control the mutual intelligibility of a language in the society of its users. The more the society is dynamic the more norms of its language change. Therefore it is recommended that the language pedagogists must be seasoned professionals who can design and interpret the language programmes (the curriculum) and domesticate the contents of it to promote the full utilization of the language of instruction for the growth of the society in all fields. KeyWords:- Language, Norms, Code, Construct, Convention, Mutual Intelligibility and Pedagogy.
The expanding bacterial resistances to antibiotics have become a growing concern worldwide. Gomphocarpus purpurascens is one of the indigenous traditional medicinal plants in Ethiopia. The objective of this study was to evaluate antimicrobial effect of G. purpurascens against standard and clinically isolated microorganisms. The G. purpurascens plant leaves and root was collected from Gondar Zuria Woreda was shade dried and powdered using wooden-made mortar and pestle. The powdered leaves were extracted by using ethanol, methanol and acetone. The extracts from the leaves and root barks with different concentrations were tested for their antimicrobial activities against selected microorganisms. Minimum Inhibitory Concentration (MIC) and Minimum Bacterial Concentration (MBC) were determined against test organisms. The most sensitive bacterial species to the highest concentration of the extract from the leaf was clinical S. aureus strain with inhibition zone diameter of 17.66 mm; whereas the least sensitive bacterial species was clinical isolate of E. coli with inhibition zone diameter of 6.54+0.13 mm. These research findings suggest that G. purpurascens plants may contain antibacterial and antifungal compounds. These plants can be a potential source for the development of antibacterial and antifungal drugs.
The association of UBE2E2 rs7612463 and KLF14 rs972283 gene polymorphisms with type 2 diabetes (T2D) was recently identified in East Asian and European genome-wide association studies, respectively. However, the replication studies in various populations showed inconsistent results. The aim of the present meta-analysis is to investigate this inconsistency, especially in Asian populations.A systemic literature search inclusive to July 2018 yielded a total of 15 potentially relevant articles withe 20 eligible studies concerning the association of UBE2E2 rs7612463 and /or KLF14 rs972283 with T2D in Asian populations.

The drug war of President Rodrigo Duterte was the centerpiece of his campaign and arguably the rallying point and core of his presidency. Despite furtive efforts to wipe the Philippines clean of illegal drug trafficking, this war has still become a subject of controversy and domestic and international criticism. This study poses questions of whether this would have positive or negative implications to peace and order, as well as gauging its impact to Filipinos who are affected directly and indirectly. Collateral damage with this kind of βwarβ has become a common occurrence. Often, innocent people are most vulnerable: citizens who belong to the poorest demography of the country. It is the aim of this study to present factual data and interviews to quantify the effectiveness and efficiency of the implementation of the war on drugs of the President. Perspectives and points of view of those involved in the implementation of the program are local officials from the most affected barangays in Metro Manila, specifically in Quezon City who were among the respondents of this study. Aspects such the respondentsβ residency as well their observations on the drug trade and crime rates before and during the Duterte administration were extracted to validate accomplishment reports or secondary data published by the Philippine Drug Enforcement Agency (PDEA). In summary, data revealed satisfactory results which is a clear validation that the drug war of the government was effectively and efficiently carried out by government security forces and other state actors. Corollary to this, it was clearly manifested that positive effects to peace and order were visible and can be reflected through the countryβs improving safety and security atmosphere. This study presents the strong points of the war on drugs program of the current administration, hence, a powerful anchor towards the continuous implementation and a founded plea towards its support from the Filipino people.
Background: Unsafe medical practices and care can be the cause of disabling injuries, infections and death. Every day millions of patients visit healthcare facilities to seek treatment of various ailments. In other words, healthcare professionals regularly hold in their hands the lives of others making it very delicate service and reason why healthcare services have been given the status as essential services. The precious lives of many people in the society to a large extent left in the hands of health professionals such as doctors, nurses, and para-medicals. According to the World Health Organization (WHO, 2010) patient safety is defined as practices and processes or structures that reduce the probability of adverse events resulting from exposure to the health care system across a range of diseases and procedures. Objectives: i) To assess patients perception and knowledge on potential risks factors and incidents/accidents ii) To assess health workers perception and knowledge on patient risks and safety practices in both hospitals for policy interventions. Methods: The study compares a select example of health and safety practice among one of Ghanaβs strong representation in the health sector-Christian Health Association of Ghana with that of the public health facility of Ghana Health Service, both located in the then Brong-Ahafo Region of Ghana. A mixed but non-intervention approach was employed to this research study with Qualitative and Quantitative approaches. A Descriptive but comparative cross-sectional survey design was used for the study. Structured questionnaires were used to obtain data from patients and staff to address the objectives Results: Overall, patients rated the performance of the two hospitals according to Excellent, Very Good, Good, Poor and Very Poor. Respondents from Wenchi hospital (32.95%) rated Excellent compared to only 5.37% from Sunyani Hospital. Similarly, 46.59% from Wenchi rated Very Good compared to 33.56% from Sunyani. Overall, 19.35% of health workers in Wenchi Methodist Hospital (WMH) rated very good while 5.38% rated same in Sunyani Regional Hospital (SRH) in terms of their hospital preparedness towards policy intervention on Patient Safety. Conclusion and Recommendations: Two important approaches must be considered in ensuring patient safety. That is, person-centred analysis and prevention approach and the systems-centred approach. In the person centred approach, individuals must assume personal responsibility to prevent incidents while the system approach ensures that working conditions do not promote individuals to commit medical errors.
In this study numerical solutions of time-independent Schrodinger wave equation (TISWE) under infinite potential well were analyzed. The TISWE is reduced to computationally tractable form by using Galerkin method and then the approximate solution is analyzed on the interval [-1,1] and Chebysheve polynomials were used as a trial function. The approximate solutions generated using this numerical scheme is highly accurate and physically acceptable. Finally the result is compared with the analytic solution which shows that this numerical method is one of the finest numerical methods to find approximate solutions of TISWEs.

Conclusion: so caryophyllene oxide is the best compounds for focusing inhibitors of estrogen receptor alpha because it possessed the best value in molecular docking.
Comparative analyses, as well as the performance of optically transparent materials such as glass, Mylar, quartz, PET and PEN, were presented. Different methods of measuring techniques have been used to determine the dielectric property of the optically transparent materials at low and high frequencies. Due to the unavailability of materials, time and test equipment in the antenna laboratory, three (3) methods were implemented in this research. Namely, split cylinder cavity resonator, quasi-optical mm-wave measurement technique and the matching technique, where simulated return loss matched with the measured value of a simple micro-strip patch antenna. An Electromagnetic (EM) modelling tool (i.e. Computer Simulation Technology, (CST) Studio suite) that takes into consideration finite integration techniques to execute computational analysis (i.e. Simulations) had been used in the matching technique to extract the physical properties of the material under test, by comparing measured and computational data. A frequency range of 8GHz-10GHz was used in the split resonant cavity measuring Glass, PET, and PEN at low frequencies. This method did not give accurate readings on glass simply because its measurement for accuracy was limited to low dielectric loss materials. Therefore, a glass material with high loss property at low and high frequencies could not be a good candidate for a split cylinder resonant cavity method regardless of its size and thickness. As shown in table 3.1, the loss tangent of glass (1.11mm) was noticed to be the same as the low-loss values of PEN and PET materials with 55Β΅m, 0.131mm (i.e. 0.00622, 0.00608, and 0.00358). However, Quasi-optic millimetre measurement bench was able to depict the real loss properties of glass at low and high frequencies. The frequency ranges of 75GHz-110GHz and 220GHz-325GHz were used in this method. The results from this reading showed that glass is a material with very high loss at low and high frequencies. Mylar, on the other hand, is the optically transparent material with the lowest loss property. However, due to its complexity in fabrication and measurement at high frequency, the Matching Technique was, therefore, more preferable. The Matching Technique was observed to be more efficient and reliable.
Two power supply systems, namely supply from National Grid and Embedded Supply in Trans-Amadi Industrial Layout Port Harcourt Rivers State, Nigeria are modeled. MATLAB/SIMULINK was used to model a comparative reliability index to see the impact Embedded generation has had on a particular feeder that was previously connected to the National Grid. The analysis also included a study of the impact Embedded Supply had on Revenue, Fault and Consumption pattern of the customers using the Comparative (Mathematical) Analytical method. The analysis showed the increased performance experienced with Embedded Supply in the areas of reliability indices, faults, revenue, and consumption. The results showed that SAIFI for embedded supply had 15 fewer interruptions and the customer also experienced 11 hours overall improvement in SAIDI and a 39% improved availability from the ASAI analysis. While CAIDI showed no improvement, load shaving improved by 4% and revenue of the feeder studied also improved by 36% this was mainly due to reduced outages on fault and improved consumption by 54%. The study will serve as a guide in informing decision-makers on how to allocate scarce resources in the power industry to maximize benefit using what is already obtainable in the country. It will also better highlight the benefits of embedded generation for private investors who may want to venture into the power supply.

This study has been carried out mainly for the assessment of naturally occurring radionuclides i.e 40 K, 238 U and 232 Th in rain water samples collected from five LGAs in Akwa Ibom State, Nigeria. The activity concentrations of the naturally occurring radionuclides 40 K, 238 U and 232 Th in the rainwater samples were measured by the means of a gamma-ray spectrometry using a sodium Iodide Thallium doped NaI (TI) detector.
Aquaculture sector provides Food, Employment and Prosperity to the people. The vast area of water resources available in the country provides huge scope for expansion of aquaculture for the production of finfish and shellfish. In order to enhance farmersβ income, there is a need to increase farm productivity through technological interventions, improve market access, and also to develop the industrial and service sectors to support various farmer activities in terms of marketing and processing of their produce and other requirements in terms of self-employment/employment in farming sector. The farmers can realize the doubling of their income within a contemplated period of five years by implementing recommended technologies in the farming system and reap the consequent social and ecological benefits.
In order to meet global energy demands with clean renewable energy such as with solar photovoltaic (PV) systems, large surface areas are needed because of the relatively diffuse nature of solar energy. Much of this demand can be matched with aggressive building integrated PV and rooftop PV, but the remainder can be met with land-based PV farms. Using large tracts of land for solar farms will increase competition for land resources as food production demand and energy demand are both growing and vie for the limited land resources. Land competition is exacerbated by the increasing population. These coupled land challenges can be ameliorated using the concept of agrivoltaics or co-developing the same area of land for both solar PV power as well as for conventional agriculture.A coupled simulation model is developed for PV production (PVSyst) and agricultural production (Simulateur mulTIdisciplinaire les Cultures Standard (STICS) crop model), to gauge the technical potential of scaling agrivoltaic systems. The results showed that the value of solar generated electricity coupled to shade-tolerant crop production created an over 30% increase in economic value from farms deploying agrivoltaic systems instead of conventional agriculture.Crop yield losses to be minimized and thus maintain crop price stability. In addition, this dual use of agricultural land can have a significant effect on national PV production. If this dual use of land is implemented nationwide, it can make significant impact by generating over 16,000 GWh electricity, which has the potential of meeting the energy demands of more than 15 million people.
In India because of the least expensive cooling method of greenhouse, natural ventilated types of greenhouses are considered to be the most acceptable structures for growing of vegetable and flower crops. In natural ventilated greenhouse, the inside air temperature is affected by its geometrical dimensions, span, orientation, ventilation rate etc. In the present study, efforts have been made to study the diurnal variation of inside air temperature during January to April months for three different types of natural ventilated greenhouses constructed at Junagadh Agricultural University campus From the study it was found that for Type-I, Type-II and Type-III greenhouses, inside air temperature was varied from 13.520C to 35.130C, 11.540C to 36.870C and 12.430C to 31.590C respectively for January month 14.880C to 38.870C, 16.310C to 35.900C, 13.210C to 33.400C for February month, 16.830 C to 27.970C, 24.4 to 46.620C, 20.440C to 46.620C, 20.570C to 41.350C for March month respectively. In April month it was found to be 22.310C to 48.800C, 22.170C to 43.400C for type-II and type-III in April month respectively. The variation in average ventilation rate per minute from January to April months were observed to be 1.7 to 1.9, 2.0 to 2.3 and 2.1 to 2.5 respectively for type-I, II and III. The mathematical models developed for soil bed and pot cultivation conditions using the energy balance equations and comparison of predicted temperature values with measured data has shown good fitting to the pattern of diurnal variation of weekly average temperatures for all the three types of greenhouses. The maximum fitting efficiency of the models was found as 94%, 77% and 98% for type-I, II and III respectively.
Water and electricity are priced resources for agricultural production system, which correspond to each other because of parallel significance in this sector besides this around 40% of world population sustaining their livelihood on agriculture, some are living in poverty. Introducing of solar power to meet extra demand of electricity can boost the agricultural production and production system as well. This has became popular and increasing fast due to enhanced cost-competiveness, environmentally suitable, energy security, convenience, and applicable marketplace. Saurashtra, one of the major cotton growing regions in the Gujarat state. Scheduling of irrigation thus become important in cotton. Drip irrigation generally save 30% of the water for cotton. If mulch is conjointly adopted with drip system an additional 10% more water can be saved which is generally lost in evaporation from moisture bulb. Hence, this sound practice is adopted for Bt. cotton. In the present arena of climate change the temperature is going to be enhanced by 1oC which ultimately enhance water requirement and frequency and on the other hand reduce the water availability to crops. So we are sand witched between low water availability and high crop water demand.This study was undertaken to address issues concerning the welfare of cotton growers in the Saurashtra state of Gujarat. In which,crop was irrigated with the help of soil moisture sensors based drip irrigation along with mulch. Renewable source of energy used to pump the irrigation water. Results revealed that around 60% irrigation water saved along with energy.
There has been a rise in consumerβs demand for safe and healthy food due to increasing concerns over the quality of food, contamination due to chemicals, serious health hazards and environmental issues. This increasing demand has given way to a new stream of agriculture, popularly known as Organic Agriculture. Since the use of huge quantities of chemical fertilizers in the Indian farming has been stopped since the Green Revolution, it has changed the structure of our land. Today, the fast-growing agricultural land is changing in the wasteland. And millions of crores of rupees are being spent on the chemical fertilizers. The use of chemical fertilizers in the fields is also adversely affecting crop yield. Organic farming is being promoted to solve all these problems. Under organic farming, farmers have to take more yields by saying the resources available to them. Use more and more organic fertilizers instead of chemical fertilizers. This paper highlights the practices of organic farming adopted by the farmer of Vadal, Dist. Junagadh, Gujarat for the production of various Agriculture and Horticultural crops exclusively by using farm made compost, vermi compost, Jivamrut cow urine etc. with higher productivity and better return. Key Words : Organic Farming, Organic Fertilizers, Chemical Fertilizers, Horticultural crops

The Evaluation of the analytical properties of synthesized glutaraldehydephenylhydrazone (GPH) on the metals (Cd, As, Pb, and Cr), the reagent GPH revealed a wavelength range of between 360.0 (Cr) to 395.0 nm for (Pb and As) as maximum absorption at a working pH of 6.5 to 7.5 room temperature (37Β°C). The reagent had a molar absorptivities (L mol-1 cm-1) ranging from 2.213 x 104 (Pb) to 2.460 x 104 (As), a mole ratio of metal to ligand of 2:1, a detection limit (Β΅g/g) ranging from 0.3432 (As) to 0.5250 (Pb) and the metal-ligand complex was stable for 0-48 hours. The reagents had a Beerβs law validity range (mgL-1) of 0.001 to 100. The preliminary investigations of GPH as possible chelating reagents for the UV-Vis spectrophotometric determination of lead (Pb) on waste water and waste water soil from tannery was carried out, and the result were compared with results from Atomic absorption spectroscopy (AAS) methods. The results obtained were satisfactory with good precision for the GPH methods.
One of the three broad objectives of the Federal Government of Nigeria's economic recovery and growth plan (ERGP) is to build a globally competitive economy, with key executive priority of stabilizing the macroeconomic environment. Macroeconomic police instruments such as the interest rate and exchange rate remain prime monetary drivers of growth and competitiveness in any economy. This empirical study therefore proffers response to the question of which of interest rate and exchange rate makes more significant contribution to economic competitiveness in Nigeria. We have employed Ordinary Least Square Regression technique to measure the impact of interest rate and exchange rate on GDP using data spanning from 1981-2016. Results reveal that exchange rate has more significant impact on economic competitiveness than interest rate. The Federal Government of Nigeria is therefore advised to implement policies to improve the exchange rate system in Nigeria.
Nigeria is a pluralistic society with diverse culture and with the antecedent of criminal and insecurity activities. However Nigeria government with a view to promoting national security has established multiplicity of security outfits to cater for national security. For security to thrive in such situation there is need for intelligence sharing among these security agencies. Surprisingly, the multiplicity instead of achieving the utmost security among all odds, they promote lack of cooperation, ego boosting, favouritism, marginalisation among the various security outfits. Individual outfit keeps its intelligence gathered within itself with a view to promoting unnecessary relevance and competition among other outfits rather than sharing intelligence together to achieve common purpose. The study therefore examined the challenges of intelligence sharing among the Nigerian security agencies and the government that ought to execute intelligence report shared with it. Ironically, the politicisation of intelligence shared with government itself makes a mockery of intelligence sharing among the security outfits. The study also rests on observation and literature on intelligence and security highlighting the challenges of security outfits in Nigeria with their overlapping functions. The paper therefore recommends collaborative effort in intelligence sharing between the security agencies and government, de-politicising intelligence and more provision of security facilities to help gather information timely in order to forestall impending dangers.
Construction management suffers from many problems which need to be solved or better understood. The research described in this paper evaluates the effectiveness of implementing the Last Planner System (LPS) to improve construction planning practice and enhance site management in the Saudi construction industry. To do so, LPS was implemented in two large state-owned construction projects through an action research process. The data collection methods employed included interviews, observations and a survey questionnaire. The findings identify major benefits covering many aspects of project management, including improved construction planning, enhanced site management and better communication and coordination between the parties involved. The fact that the structural work in one of the projects studied was completed two weeks ahead of schedule provides evidence of improvement of the specific site construction planning practices. The paper also describes barriers to the realization the full potential of LPS, including the involvement of many subcontractors and peopleβs commitment and attitude to time. KEY WORDS: Construction planning, Last Planner System implementation, action research

The purpose of this study was to determine the moderating effect of intellectual engagement on the asso-ciation between peer relationship and social-emotional and character development among the elementary students in Caraga Region. Non-experimental quantitative research utilizing descriptive correlation technique was the design employed in the study. Respondents of 400 students from public elementary school in the 10 divisions/cities in the region were chosen through random and stratified sampling. Results revealed that the level of peer relationship was moderate while social-emotional and character de-velopment and intellectual engagement were high. Further, findings revealed that peer relationship and intellectual engagement are significantly related to social-emotional and character development. Importantly, results revealed that intellectual engagement demonstrated significant moderating effect on the relationship between peer relationship and social-emotional and character development. Intellectual engagement provides more profound effect on the relationship between peer relationship and social-emotional and character development. With these three constructs as support system superior perfor-mance and competitiveness among the elementary students may be expected. Keywords: education management, intellectual engagement, peer relationship, social- emotional, character development, Philippines.
Taboos, totems, and rituals as belief systems have been very instrumental in conserving species in different African communities. This study was therefore carried out to assess how these belief systems contribute to species conservation in Mount Cameroon Area. An interviewer-administered questionnaire, focus group discussions, and in-depth interview sessions were conducted in 8 of the 41 villages within the Mount Cameroon Area in 2017. The study found out that 50% of the respondents still perceive taboos, and totem practices as key traditional practices contributing to the conservation of animal, tree and bird species including endangered species like the African Elephant and Nigeria Cameroon Chimpanzee. Though contributing to natural resources conservation, these belief systems are not cherished and respected by the younger generation and an increasing number of community members due to the adoption of Western culture and Christianity, as well as urbanization. The study, therefore, recommends that a detailed study be carried out on the effectiveness of incorporating traditional belief systems into law enforcement mechanisms for the conservation of natural resources to understand the complementarities of traditional belief systems and law enforcement in the achievement of conservation goals.

Ready made garment (RMG) industry is the key sector of the Bangladesh's economy in terms of Employment, production and foreign exchange earnings (World Bank, 1990). There are at present more than 4500 garment factories contributing about 80 percent of the country's export earnings. This tremendous success is greatly attributable to women workers, who account for the lionβs share of the total labor force employed in the sector. But women were exploited easily due to lack of technical knowledge and training. Globalization as manifested in the RMG sector, failed to offer opportunities to the female labor force. Garment industries were exploited them as cheap source of labor (Halim and Kabir, 2005). In the garment factory, most of the female workers age is between 18 to 30 years. Qualitative methods were used in order to get a reasonably true picture of the entire population. The data were collected during the period from February to April, 2019. This study find out what are the main reasons to becoming a women garments worker, what the problems they facing during her garments life and to recommend some measures to improving the problems of RMG sectors female worker by this study.
Objectives : The medical imaging is one of the specialities of the medicine which the most profited from computerization these last decades through the installation of the system from filing and of communication of the medical images (IF) which starts to become an option impossible to circumvent.This system allows a medical step in which the professional of medical imaging joins together in a virtual form all the relevant data for a holistic and effective approach of the customer.The study consisted in arising the importance of the establishment of and the filing communication system of images within certain medical establishments and its influence on the medical practices. Method : For that, one six months duration, a descriptive cross-sectional study was undertaken in the services of imaging of the General Hospital of Douala and Yaounde and of the Regional Hospital of Garoua, functioning already with these systems of computerization. The data were collected using a preestablished standard questionnaire, then filled by the professionals of health of the services of medical imaging of thats sanitary structures. Results: Engineers in imagery (55%) whose age bracket varied between 19-28 years were in a majority and 60% of the professionals had never received a training in information system.75% of use of the information systems were based on the visualization of the images taking into account its facility of use. 60% of the radiologists users of the Information systems found them beneficial for their services.34,6% of the systems were equipped in majority with the application "management with the patient file". The speed of use of the functions "visualization of the images" was better in 70% of case.

Credit risk is one of the most critical areas of financial research of late. It is motivated by recent progress in risk management portfolio and techniques in management, trading in Credit growth derivatives, implementation of Basel II accord and concerns from regulators driven by credit crisis that occurred in the USA between 2001 and 2002. Within this vast literature, advances in research provides an analysis of the role, influence and meaning of the Credit ratings that merit Credit Risk. This paper analyses the links which are two way between Macroeconomic states and Credit risk assessment deciphered through business cycles phases. We propose a technique or methodology which can be applied in Banks data and is internally rated having project migration of ratings and their probabilities as well as integrating the economy state. We discuss first the matter on whether the risk of credit is low or high in diverse states of economy. In order to discuss these scenarios, we scrutinize each year having four quarters representing different states within the year. We then review how conservation of macroeconomic are integrated in models of Credit Risk and approaches in risk measurements having Basel II and Basel III as their core approach.
