The study of the research was on the basis of the need to identify a correlation of susceptible cases of overuse strain in deaf individuals for potential leads of future research in addressing the healthcare needs in sign language institutions. This study aimed to identify upper extremity pain prevalence in deaf individuals caused by susceptible overuse strain. The research framework was constructed in a two-phase self-analysis; the first-phase, entailing the respondents’ current level of pain by means of the NRS & IPT pain scales, and the second-phase; entailing the respondents’ weekly past account of functional limitations extrapolated from the SMFA and DASH questionnaires under a Mixed Quantitative Survey/Interview methodology. The area chosen for the research was in Labangon, Cebu City, within a particular sign-language institution. The respondents of the research were strictly deaf individuals enrolled in the particular sign-language institution. The findings of the research indicated that there was an 85% prevalence of susceptible DASH score indicating the prevalence of susceptible overuse syndrome, with an 82% comprehension rate among respondents to the examination. There is an indication of a call-to-action to fine-tune current assessment tools to adequately be utilized by deaf groups in need of care, and an overall need to expand provider skills based on the findings.

This paper presents the findings of a qualitative research that was conducted to find out the impact of coronavirus (COVID-19) pandemic on the informal sector in Zimbabwe. Given the health scare and crisis induced by COVID-19, the government of Zimbabwe like many other governments across the world enforced a lockdown. The lockdown measures affected various businesses in different magnitude. This paper interrogates the effects of COVID-19 lockdown on informal traders such as vendors, taxi operators, welders, carpenters, illegal forex dealers and cobblers in Bulawayo and Masvingo cities of Zimbabwe. Purposive sampling was used to identify the respondents from selected high-density suburbs. Data was collected using in-depth interviews. The paper revealed that COVID-19 lockdown measures had a negative impact on the informal traders’ livelihoods. The article notes that the impact of COVID-19 lockdown in Zimbabwe was worsened by several factors among them, short notice in proclaiming enforcement of lockdown and the country’s dire state of the economy. While this research gives a description of how the informal sector revenue declined drastically following proclamation of lockdown measures, the article also offers the steps that can be taken to rebuild the informal sector. Key among these steps, is the government’s intervention to capacitate the needy families.
The rise of the internet and its applications have revolutionised not only the practice and profession of journalism but also how media texts are consumed by audiences. This article reports the results of a qualitative research that was undertaken to find out the opportunities and challenges brought by the internet to media audiences. This paper interrogates the contribution of the internet and its applications to the role of traditional public media using the case of Zimbabwean audiences. While the article reveals that the internet has brought both positive and negative changes to media audiences, it stresses that the way audiences receive and interpret media texts have been transformed by technological advancements. While some scholars have lauded the internet for ushering 24/7 journalism and interactive platforms, this article highlights that the internet has been embraced as a blessing to media audiences in Zimbabwe. The internet does not only offer alternative news sites to public media audiences but also operates alongside old media and competes with traditional media in breaking the news.
The present research focuses on composition of comets depending on the process of solar wind charge exchange (SWCX). The chemical composition of cometary nuclei was inferred from measurements of neutral and ionized gases from the coma, tail, and dust grains. Cometary high-energy emission depends on properties of both the comet and solar wind. Data were obtained from Chandra X-ray space telescope for two comets, one of them come from Kuiper Belt, namely, 46P/Wirtanen and other originating from the Oort cloud namely 153P/Ikeya–Zhang Comet. Observed at energy range (100-10000) eV. The results of present work showed a relation between photons count and energy to estimate the structure of the comets, also we found that the comet come from Oort cloud contain four elements but the other contain eighteen elements furthermore, determined the abundant of each element.

A comparative analysis of cocoa production in Ghana and Nigeria was carried out to determine the importance of government policy. The progression of the value chain from cocoa beans to chocolate-the most important product- was compared. The study highlights the highs and lows of the cocoa trade in both nations over six decades. The full exploitation of raw materials produced in Sub-Saharan regions of Africa is a major problem. Cocoa was used as a case study to evaluate the impact of sustained government policy guidance on the exploration and exploitation of raw materials. Historical records of export quantity, price fluctuations, production challenges, and policy interventions were stated to give a balanced and encompassing comparison of the situation. Lists of cottage industries in the chocolate sector of both countries were added to support the argument. The factor which stood out was the consistency of government support and policies led to further exploration of the value chain.
This study covers the pre-germination treatment of the seed of Anacardium occidentale (cashew) and its early growth in the nursery. The plant height, stem girth and number of leaves were examined. The seeds were subjected to 6 (six) different pre-germination treatments, before they were sown directly into polythene bags filled with top soil. The experiment was laid out in complete randomized design consisting of six (6) treatments with control and each was replicated five times. The data collected in the course of the experiment was subjected to analysis of variance (ANOVA). The means were further separated using least significant difference (L.S.D) where significant differences were observed. The readings from the experiment were taken over ten (10) weeks. Germination result showed that all the treatments grew up except treatment D seeds which were cracked. Height result from showed that treatment (C), seeds soaked in water for 24 hours had the highest growth of 15.66 cm at week 1 and 31.74 cm at the 10th week. The result of analysis of variance for periodic changes in the height revealed that there was no significant difference among the treatments applied at 0.05 level of probability. Leaf count shows that treatment C was ahead of other treatments at week 1 with 5, while at week 10, treatment C took over the lead with leaf production of 14.80. The result of analysis of variance for periodic changes in leaf count revealed that there was no significant difference among the treatments applied at 0.05 level of probability.

Thermal properties of polyvinyl alcohol (PVA) doped with silver nitrate (AgNO3) composite films synthesized by casting method has been investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The effect of the addition of AgNO3 to PVA was studied. The results indicated that the addition of AgNO3 led to a more compact structure compared to the pure PVA which resulted in an improvement in its thermal stability with an increase in the isotropic character of the polymer samples. The results also clearly demonstrate that the composite films of AgNO3 and PVA are more stable at higher temperature than pure PVA. Samples were irradiated with gamma rays in the dose range 0-10 Gy. The variation of onset temperature of decomposition, glass transition temperature and residual mass has been investigated. Thus, this work suggests the possibility of using the gamma irradiated PVA/AgNO3 films in different electronic and semiconductors applications.
