Leiomyosarcoma (LMS) of sigmoid colon is extremely rare high grade neoplasm with poor prognosis. Gastrointestinal leiomyosarcoma are aggressive mesenchymal tumors. Here we present an unusual case of leiomyosarcoma of sigmoid colon with adhesions and perforation in small intestine. Case presentation: A 65 years old male patient referred to our institute with complaints of vomiting, pain and distention of abdomen .Clinical examination showed rigidity and guarding of abdomen with diminished bowel sounds. Clinically diagnosed as intestinal obstruction. Colonoscopy revealed growth at recto-sigmoid junction. Histopathology of biopsy reported with differential diagnosis. Malignant gastrointestinal stromal tumors (GIST) and Leiomyosarcoma. Immunohistochemistry confirmed the final diagnosis. SMA positive and CD117 negative. Hence diagnosed as leiomyosarcoma of rectosigmoid colon. Conclusion: Colonic leiomyosarcoma is rare and its occurrence in rectosigmoid colon is unusual. Leiomyosarcoma can be differentiated from GIST by IHC marker.

The goal of this study is to determine the level of awareness of Green Human Resource Management (GHRM) among Human Resources (HR) Managers and HR officer at various levels in the Nigerian oil and gas industry. To collect data, a cross sectional design using quantitative research methodology was used. Data were obtained from 180 HR managers and HR officers in the chosen study organizations. Theory of green economy underpinned the study. The descriptive data analysis is given in relation to the level of relationship between the variables, and a regression analysis was used to determine the predictability of the corporate sustainability using the independent variables (GHRM). The findings of the study showed significant relationships between the independent variables (green recruitment and selection, green training and green rewards management) and corporate sustainability (r = 310, .469, .417; p < .01) respectively; and F (3, 176) = 30.43, p = .000, with R2 of .342 showed that GHRM is a good predictor of Corporate sustainability. The study recommended that to attain outstanding corporate sustainability, organizations should implement the necessary GHRM practices. Schools should include Green activities in their curriculum so as to inculcate and imbibe the culture of green practices. Finally, the government should incorporate GHRM methods into Nigerian Labour law and promote firms that adopt green HRM.

There are many descriptions of the environment in William Yeats’ poems. From the perspective of new historicism, this paper analyzes the ecological images of poetry from two aspects: the historicity of the text and the textuality of history. Ecological images are those depicting nature and cities. Among them, birds, roses, and Innisfree are the classic ones. Through these images, William Yeats concerns the relationship between the ecology and people. The historicity of the text presents the historical reality of Ireland and Irish life experience. Then, based on the function of literary texts which work as an ecological reality, the thesis explores the assimilation and arrogance of humans in constructing Irish life experience. The textuality of history focuses on fiction and historic reality. Through the images, Irish ecology enters the public. Moreover, William Yeats applies defamiliarization and intertextuality to contrasting the authoritative history and offering a fresh history.

Students’ achievement in core subjects in the West African Secondary School Certificate Examination (WASSCE) has been a subject of concern for stakeholders due to poor performance. The purpose of this study is to assess whether item difficulty is a significant source of variability to the measurement of students’ achievement in WASSCE in Ghana, using the generalizability theory. The study had three specific objectives: (1) to examine the sources of variability (e.g., item) to students’ achievement in WASSCE in Ghana, (2) to assess the dependability of students’ responses in relation to their ability, (3) evaluate how many items are sufficient to provide an optimum measure of student achievement. The one-facet crossed random design was adopted as the research design. Data were obtained from students’ achievement in 2015 WASSCE in the four subjects, namely, Mathematics, Science, Social Studies and English Language. The generalized analysis of variance (GENOVA) was used for the analysis, conducting both G-study and D-study. The analysis revealed that the findings from this study showed that item difficulty had minimal effect on the variability in students’ achievement in English Language and Mathematics. The result further revealed that item difficulty had a significant effect on variability in students’ achievement in Science and Social Studies. Only the English Language test showed relatively low reliability. The study recommended the item difficulty and content structure of the Science and Social Studies multiple-choice test should be evaluated by WAEC officials and their examiners.

Introduction: Recurrent pregnancy loss (RPL) is considered as a significant public health problem. In many studies, Factor V Leiden mutation is considered to have significant relationship with unexplained recurrent pregnancy loss. Aim of the study: The aim of this study was to determine the association of Factor V Leiden mutation with unexplained recurrent pregnancy loss. Methods: This case-control study was conducted in the out-patient Department of Fetomaternal Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, from November 2020 to April 2021 (6 months). Sample size was taken as 40 for each case and healthy control group. Result: Mean (±SD) age was found 28.2±4.9 years in RPL group and 27.1±5.24 years in non-RPL group. Maximum number of patients fell into the BMI category of 23.0-26.9 kg/m2 (BMI for Asian women) in both groups. Among the RPL cases, 30% had experienced consecutive 2 pregnancy losses with mean (±SD) number of losses 3.07±1.14. About more than half percentages (n=23, 57.5%) shared the primary RPL group. In this study, normal homozygous FVL mutation was equally distributed among RPL patients and control individuals. Only 2 cases (5%) were found positive for Factor V heterozygous mutation (GA) in the RPL group. G allele occurred in most of the cases (97.5%) of RPL. Two cases aged 25 years and 35 years respectively were found positive for heterozygous mutation of Factor V Leiden. Both of them exhibited 3 consecutive recurrent second trimester pregnancy losses. Factor V Leiden was found in higher prevalence (100%) in 2nd trimester recurrent pregnancy loss sub-group of cases and revealed significant association (p <0.001) between two variables. Conclusion: The impact of Factor V Leiden mutation has not stated any causal association with unexplained recurrent pregnancy loss. The results do not support Factor V mutation screening as an initial approach in Bangladeshi women suffering from recurrent pregnancy loss.

Background: Multidrug resistant Acinetobacter baumannii, (MRAB) is an important cause of hospital acquired infection. The purpose of this study is to evaluate the epidemiology and analyze the level of antibiotic resistance of Ab strains in the intensive care unit of the ibn Tofail Hospital of the Mohammed VI University Hospital of Marrakech. Material and method: This study is a retrospective review of a city hospital epidemiology data base and includes 42 isolates of Acinetobacter baumannii (AB) from 120 patients. The antibiogram was performed according to European Committee on Antimicrobial Susceptibility Testing (EUCAST) recommendations. Results: In our study, all bacteriological samples were taken from the intensive care unit. The mean age was 48.2 years with extremes ranging from 19 to 72 years.88 patients were male (73.4% of all cases) and 32 female (26.6%).The most frequent reason for hospitalization in the intensive care unit was severe head trauma in 35 cases (29%).During the study period, out of 120 samples received, 42 Ab strains were isolated (35% of samples). These strains were mainly isolated from blood cultures (40%). Conclusions: The diffusion of multi-resistant Ab strains in intensive care units seems to be alarming, hence the need to implement an effective strategy to fight nosocomial infections.

Background: In the 21st century dentistry has not only reached an epitome of great inventions but also has established a great milestone in achieving efficiency, efficacy and technological advancement. Technology has not only helped dentistry to grow in its value but also has encouraged the dentists to introduce less traumatic procedures. The course of periodontal disease is obvious by the sporadic and intermittent pattern of disease activity and inactivity showing random or alternate exacerbation and remission. Although microbes were considered to be the primary etiology, they were insufficient to cause a disease all by themselves, environmental, systemic and host response were also a part of the etiotrophic factors. Hence, to understand these complexities various assessment tools and advanced diagnostic aids were developed and introduced in practice. The various chair side diagnostic aids include Advanced Periodontal probes, Advanced radiographic diagnosis, Advanced microbial analysis, advanced immunodiagnostic techniques and molecular biological assays, Advanced biomarker identification and genetic testing and Advanced Chair side diagnostic kits. This manuscript reviews the advancement in the recent chair side diagnostic kits which are frequently studied and relied upon.

The lips represent an important role in social life as they are used to ease phonetic articulation, complement the aesthetical structure of the face and, they serve as a means of giving nutrients to the body. In certain cultures, they are crucial external signs of femininity and serve different purposes. Given the complex functions of these structures, reconstruction of labial defects presents a challenge for plastic surgeons not only in the management of tumor pathologies, but also in cases of emergency post-traumatic amputations. In the present study, we shall describe a case of labial reconstruction using a tongue flap after a post-traumatic loss of tissue in the vermilion border. The surgical reconstruction technique will be discussed and then, we will present an overview of the constraints related to the treatment of the flap and finally the initial outcome of the procedures.

Price distortion caused by taxes, duties, or subsidies distorts the consumption of various goods and services. When prices become misleading they produce wastage and provide little or no incentive for conservation. Electricity tariffs are subsidized in Gulf countries due to socioeconomic and political reasons but with ongoing petrol prices and the Covid-19 situation, Oman is slowly moving toward removing subsidies. According to the economic theory of efficient pricing, the prices of goods should be set equal to their marginal cost of production. The purpose of this paper is to provide a methodology to estimate long-run marginal cost (LRMC) at the generation level using a traditional generation expansion planning software. The approach is then applied to find LRMC for Oman’s Main Interconnected System (MIS). The LRMC at the level of generation busbar is then taken down to 132-kV, 33-kV, 11-kV, and 415-V. The LRMC calculation has shown that the power sector is highly subsidized.

Basal cell carcinoma is the most common human cancer worldwide. It‘s an epithelial cancer developed from epidermal tissue, happening most frequently from novo, localized only to the skin, with local malignancy. His prognosis is relatively good but premature management, in effect surgical excision is necessary, given its significant potential tissue destruction leading to high morbidity. Numerous clinical and histological types are reported, specifically tattooed or pigmented basal cell carcinoma which poses the differential diagnosis problem with melanoma. Here we report a case of Basal cell carcinoma of the face, inadequately treated for long time, noticed at an advanced stage.

All acneiform eruptions are not acne vulgaris. Some acneiform eruptions can be caused by fungal organisms that are usually not resolved with standard acne medications. Demodex is a skin mite, taking advantage of local and general factors to proliferate. They are ubiquitous in the skin but there is a predilection for the face. The diagnosis of demodicosis is based on a range of clinical, parasitological and therapeutic arguments. Screening for Demodex sp is essential to establish the correct diagnosis and ensure suitable treatment.

Tomatoes consumed in Gombe are contaminated with traces and heavy metals due to accumulation of these metals in soil that absorbed by crop plants, which is the most serious environmental problem with significant implications on human health. This study focused on the comparative studies on concentrations of carcinogenic and non- carcinogenic heavy metals analyzed based on WHO Permissible limits. Sample T1 Tomatoes showed mean concentrations in decreasing order of Zn = 0.094 ± 0.045 mg/kg followed by Mn = 0.0744 ± 0.0031 mg/kg then Ni = 0.0394 ± 0.0014 mg/kg, Fe = 0.0163 ± 0.00113 mg/kg, Cd = 0.0063 ± 0.00106 mg/kg, Pb = 0.0031 ± 0.0062 mg/kg, Co = 0.00152 ± 0.00126 mg/kg, As = 0 respectively. Sample T2 showed mean concentrations of heavy metals with the highest of Ni = 0.2095 ± 0.27 mg/kg followed by Zn = 0.1761 ± 0.134 mg/kg, Mn = 0.0487 ± 0.0023 mg/kg, Fe = 0.0233 ± 0.00195 mg/kg, Cd = 0.0147 ± mg/kg, Pb = 0.0047 ± 0.0062 mg/kg, Co = 0.0075 ± 0.0065 mg/kg respectively with few above WHO limits of 0.002 – 0.005mg/kg. Sample T3 Tomatoes showed mean concentrations with highest in decreasing order of Mn = 0.0829 ± 0.017 mg/kg followed by Ni = 0.0809 ± 0.00412 mg/kg, Zn = 0.0504 ± 0.0031 mg/kg, Co = 0.0225 ±0.00080 mg/kg, Cd = 0.0179 ± 0.00243 mg/kg, Fe = 0.0143 ± 0.00057 mg/kg. As = 0.0011 ± 0.000265 mg/kg, Pb = 0.0004 ± 0.000058 mg/kg respectively. Hazard Index (HI) of non-carcinogenic Heavy metals analyzed in Tomatoes samples showed highest hazard index in all the three pathways with Co = 3.64 E+ 00 followed by Pb = 2.71E+00 then Cd = 5.51E-01, Ni = 1.07E-02, Mn = 6.81E-03, As = 2.16E-03, Zn = 7.79E-04, while the lowest Hazard index was shown by Fe = 5.62E-05 indicating HI > 1 with adverse health risk in decreasing order of Co > Pb > Cd > Ni > Mn > As > Zn > Fe respectively. Cancer risk effects of carcinogenic heavy metals investigated through ingestion showed the highest cancer risk of Cd = 4.10E-05 followed by As = 3.23E-07 then Pb = 7.14E-06 with order of Cd > As > Pb > Co while cancer risk through inhalation showed the highest in Co = 1.27E-11 followed by Cd = 7.06E-12 then As = 4.76E-13, the lowest of Pb = 4.41E-14 with order of Co > Cd > As > Pb indicating that some heavy metals contaminated the tomatoes analyzed were projecting while hazard and cancer risk on human health will persisted on body systems at certain prolong time, examining of these heavy metals levels will safeguard public health.

Over recent years there is a huge growth in the area of wireless networks due to its efficient design. The word sensor is defined as component which handles & monitor different kinds of inputs from different sources such as physical and environmental conditions like pressure, heat, light, sound and vibrations etc. The output produced by the sensor will be electrical in nature and this electrical signal is further applied to various controllers for other functions. A Wireless Sensor Network is basically a form of ad-hoc network which consists of thousands of tiny sensor nodes. These wireless networks are deployed where the wired network implementation is difficult or impossible. These nodes are further distributed over a wide area such as hilly areas, forests, deserts, ocean etc. and these tiny sensors communicate or exchange data with each other by using radio signals. The WSN utilizes various communication protocols like Bluetooth, Wi-Fi, Zigbee and Ultra Wide Band techniques. Every protocol has its own speed and depending upon the distance between them, there are various problems which network can face like battery failure, effective coverage area, and effective energy utilization or node failure. In this paper, the several different methods to build energy efficient network, methods to improve the lifetime of a network, method for detection and correction of node failure and in the last the important applications are discussed.

Antimicrobial resistance is a major public health problem all over the globe. A cross sectional study in different zones of Hyderabad city was conducted with the aim of evaluating community pharmacists’ knowledge, attitude and practice (KAP) on antibiotics and antibiotic resistance. A self-administered questionnaire was developed as data collection tool. Responses were recorded and scored using 5-Point Likert Scale. Descriptive statistics, frequencies, percentages and statistical tests were used to analyse the data. Data was collected from 40 community pharmacists. Results showed that the community pharmacist had poor knowledge on antibiotics and poor antibiotic dispensing practice. About 31(78%) pharmacists never heard about the term antimicrobial resistance. Our study highlighted that there were only 15 pharmacists who considered antimicrobial resistance as a serious issue. Most of the pharmacists (n=20) agreed that antibiotics can be dispensed without prescription. Around 26 pharmacists dispense antibiotics to treat minor ailments without a prescription. The most common reason given by community pharmacists for dispensing antibiotics without prescription was, request for antibiotics by the patients. The study highlights that there is a need for the community pharmacists to update their knowledge and improve their awareness on antibiotic resistance. Short term, intensive training programs are needed to improve their knowledge and practice regarding antibiotic use and resistance.
