Muscle lymphoma is a very rare disorder, comprising only a very small subset of lymphoma cases. It can develop either as primary extranodal intramuscular lymphoma or as intramuscular manifestation of disseminated disease. There are characteristic imaging features which, if recognized, can prevent delay in diagnosis and treatment, particularly when not suspected clinically. We herein present a rare case of primary muscle non Hodgkin lymphoma with a description if the associated clinicopathological findings and a review of the relevant literature.

The purpose of the study was to establish psychosocial factors affecting marital stability among middle-age couples in Suneka, Kisii. The study used a descriptive research design. The target population of the research was 1000. Yaro Yamane’s formulae was used to obtain a sample size of 285. The data was collected using a questionnaire with 32 items. The data analysis was done using Statistical Package for Social Science (SPSS) version 20 and the statistics presented using frequency tables and pie charts. The results of the study indicated that contrary to God’s desire for couples—man and woman to stay together in their marriage union, there is increased divorce. This is as result of various theories about how marriage ought to be which means for couples to stay together there is need for biblical teachings to clearly state the purpose of home and the family as well as emphasize the importance of marriage, marriage enrichment, and marital commitment. However, as much as communication is at the center of a highly functioning marriage, quality sexual performance by the couples is the main tributary of it—the only key communication which enhances the joyful and thankful relationship.

Krukenberg tumors are defined as ovarian metastasis of digestive tract cancer. They represent only 1% to 2% of all malignant ovarian tumors [1]. Stomach is the most common primary site. We report an observation of Krukenberg tumor arising from a gastric cancer, discovered during the exploration of chronic abdominal pain in a 48-year- old women. The call signs were mainly digestive. Ultrasonography and pelvic MRI played a key diagnostic role. The aim of our article was to give an overview of the imaging features of typical Krukenberg tumor.

Magnesium oxide (MgO) nanoparticles were synthesized through chemical coprecipitation followed by thermal treatment. Structural, optical and luminescence properties along with dielectric properties were studied and relaxation mechanisms were explored. The structural characterization studies confirmed the formation of nano sized MgO particles with hierarchical structures and high purity. The dielectric properties were studied in different frequency range at different temperatures. In addition, the Cole –Cole plot are used to explore the relaxation mechanism prevalent in nanostructured MgO. In dielectric materials there are multiple dipole relaxation mechanisms which give rises to spreading of relaxation time on the average relaxation time.

The purpose of this study was to establish the contribution of tourism to the host community’s human capital assets. This study employed qualitative approach by the use of exploratory research design. The target population for this study included the host community, tourism investors, camp managers, Narok County tourism officers and area chief of Mara Naboisho Conservancy. Both purposive and snowball sampling methods were used to select the respondents and information. The study utilized both primary and secondary sources of information. Primary sources included interviews, observations and Focus group discussions. The findings from the study revealed that Tourism in Mara Naboisho has contributed a lot towards job opportunities, entrepreneurial skills and income generation to the host community. It was also found out that tourism contribute significantly to human capital assets to the community in terms of employment creation as well as market for the products and services. This study also recommended that the local community should be empowered to collaborate with the Mara Naboisho Conservancy authorities to set up a location whereby the tourist on their way to the park can make a stopover and have a look at the display of their souvenir and purchase them. The Mara Naboisho Conservancy authorities should support the local community through funding in order to improve the community-based projects and also improve the local sport activities. The study findings are anticipated to provide an insight that will be used by the stakeholders to improve the livelihoods of the community who are directly involved with tourism in Narok County.

Surface water resources play a crucial role in potable water delivery to many communities in Ghana. They support recreational, agricultural, and industrial water needs. However, several interrelated factors of spatial and temporal variation impact on and control the quality of these water bodies. Due to lack of protection, surface water bodies are highly vulnerable to the impacts of climate change and anthropogenic activities. This study sought to evaluate the main factors influencing the hydrochemistry of the Pra, Ankobra, and Tano rivers of the south-western rivers system using statistical, spatial, and conventional hydrochemical plots. The results revealed high turbidity and TSS levels in the rivers reaching values of 4645 NTU and 3615 mg/l, respectively. Significant levels of Fe exceeding recommended WHO guideline level was also identified. The main hydrochemical facies in the rivers were Ca-HCO3 (47%) and Mg-HCO3 (44%), with relative abundance of the order Ca > Mg > Na > K for the cations and HCO3 > Cl > SO4 for anions. Precipitation, mineral dissolution in the soil zone, and anthropogenic activities, particularly artisanal mining, were identified as the main factors influencing the quality of these rivers. However, irrigation assessment shows that the rivers are of excellent quality for irrigation.

This research was carried out to study of variation of composite flour prepared from underutilized staple food (Foxtail Millet, Naked Barley) and Legumes (Beans). Sensory, nutritional and physical properties of these products were analyzed. These variations were compared with composite flour prepared from commercially available cereal(wheat, maize) and legumes(Beans). Four formulations were prepared using foxtail millet, naked barley and legumes. The proportion of staple food and legumes were chosen in such a way that the resulting formulations contained crude protein not less than 14%. The formulations were coded as control A (wheat, maize and soybean in the ratio of 7:7:6), B1 (Foxtail Millet and Beans in the ratio of 3:2), B2 (Naked barley and beans in the ratio of 3:2), B3(Foxtail Millet and Bean in the ratio of 1:1), B4(Naked Barley and Bean in the ratio of 1:1). Crude protein in formulations ranged from 15.13±0.75 to 15.87±0.67, crude fat from 2.63±0.14 to 4.41±0.11, total ash from 2.49±0.06 to 3.36±0.36, carbohydrate from 70.71±0.45 to 73.2±0.75 and energy per 100gm from 369.99±0.78 to 386±0.65. Formulations B2 had highest Water Holding Capacity (1.77±50), Water Solubility of B1 was highest 12.86±0.24. Bulk Density of all the formulations including control A ranged from 0.49±0.07 to 0.53±0.067. Sensory evaluation of the formulations also scored high as compared with the control in taste, aroma and consistency.

Improving tomato production is one of the important greatest challenges facing Nigeria government today. Since tomato is an important fruit crop for the country and for individual households, it has important implications for livelihood of rural people. In order to achieve this, several interventions in the sector were done in an attempt to improve production. The study analyzes the tomato production from year 1981-2017. The study was carried out to examine the trend in tomato production and importation, the determinant of tomato production and the effect of tomato import on it producer in Nigeria. Secondary data obtained from Central Bank of Nigeria Statistics and Food and Agricultural Organization were used for the study. Dickey-Fuller unit root test and Co-integration test were employed to analyze the data collected. The result showed that the time series used for the study are all stationary at first difference. The result of co-integration test in the short-run Error Correction Model (ECM) estimation at 1 lag length shows that Agricultural labour, local tomato price and rainfall are significant to tomato production. The result of the long-run ECM estimation shows that Agricultural labour, local tomato price and rainfall are significant to tomato production. The result of the trend local tomato price showed it was stationary at first difference and also positively significant to tomato production at both short-run and long-run ECM estimation which indicates that local tomato price time trend has being favourable for tomato production. Result of the trend of agriculture labour showed that it was stationary at first difference and positively significant in the short-run and positively in the long-run ECM estimation to tomato production which indicates that agricultural labour time trend is inversely related to tomato production. All this can be due to the country not depending on importation of agricultural produce, food production through agriculture to the masses by the government within the country, implying that the government support production and more exportation resulting in an government increasing revenue. It is therefore concluded that more agricultural produce should be produce in the country to control importation.

This article investigates learning strategies among English Language students to what extent they apply the Explicit-Deductive/-Inductive Grammar Learning Strategies in their language learning. The students as the language learners need to acquire precisely the English grammar skills to help them fulfil their course requirements. To achieve the objective of the study, the adopted questionnaire from Language Learner Strategies developed by Oxford and Lee (2011) has been distributed to 95 samples. The findings show that there is relatively strong statistical evidence supporting all the alternative hypotheses by showing that there is a moderately significant relationship between Explicit-Inductive Learning Strategies (EILS) and Explicit-Deductive Learning Strategies (EDLS). 

Graphene oxide (GO) is an amazing nanostructured material with a wide range of possible technological applications, including its use as filler for thermoplastic polymers or thermosetting resins. A combination of graphene-related substances with other systems often leads to promising nanocomposite materials with unique mechanical, chemical, and physical properties. In this work, we study morphology and elastic properties of a composite consisting of polystyrene (PS) and graphene oxide (GO). We prepared several composite films of this nature with a varying polystyrene concentration on a fixed amount of graphene oxide. The morphology of the composites was observed by Scanning Electron Microscopy (SEM). The SEM image shows the higher the concentration in polystyrene, the more compact structure of graphene oxide and polystyrene are observed. The mechanical properties of the composite films were analyzed using Atomic Force Microscopy (AFM). It is found that the Young’s elastic modulus of the composite film changes drastically from the value of its pure constituent solutions though it shows a rather weak dependence on the polystyrene concentration for the values considered.
