  • Successful experiments with Salvia officinalis and Salvia microphylla and COVID19

    This paper presents results of the author on Salvia officinalis and Salvia microphylla and COVID19. The results were achieved with dried Salvia officinalis leaves and with fresh Salvia microphylla leaves. The properties of fresh leaves appear with the taste as being much richer in antiviral agents, drying reduces the antiviral activity. The experiments presented in this paper are on the author himself, do not involve biosampling to confirm in laboratory but existing data in the published literature confirms the excellent efficiency of Salvia officinalis against COVID19 and a large array of other diseases. The self-experiments were very successful against COVID19, opening a path for natural treatment.

  • Epithelial-myoepithelial carcinoma of floor of mouth: A case report of double clear cell variant with immunohistochemical correlation

    Epithelial-myoepithelial carcinoma (EMC) is a rare biphasic low-grade malignancy accounting for only 0.5% of all salivary gland tumors. Commonly, EMC affects parotid gland (70%) and rarely affecting other salivary glands. Clearing of both, epithelial and myoepithelial cell types, is rare and gives an impression of a monocellular neoplasm. Case report: A 42-year-old male reported to Oral and Maxillofacial Surgery Department in Faculty of Oral and Dental Medicine, Misr International University with a painless growth in the floor of mouth since 5 years. The soft tissue window of computerized tomography (CT) revealed a well-circumscribed swelling in the sublingual space. The provisional diagnosis was pleomorphic adenoma. Results: The histopathological examination showed solid sheets of rounded to polyhedral clear cells forming lobes and lobules separated by connective tissue mucoid septa. A thin fibrous capsule, invaded with some tumor cells was also present. The presented pattern of clear cells together with the encapsulation of the tumor provides an impression of clear cell variant of monocellular neoplasm. Conclusion: The presented case relates to an epithelial-myoepithelial carcinoma originating from the sublingual salivary gland, which is a rare site for this lesion. Based on immunohistochemical staining, differentiation between the double clear cell types was confirmed using S-100 protein and SMA for the myoepithelial nature of the outer cells while the epithelial nature of the inner cells was confirmed by CK-19 and EMA. Thus, the diagnosis of double clear cell variant of EMC was given.

  • The Role Of Acacia Decurrens Tree On Farmers Livelihod In The Banja Woreda

    The aim of the study assesses the role of Acacia Decurrens tree on Farmers Livelihood in the Banja Woreda. To this purpose, the study adopted descriptive survey design. The study focused on the three kebeles such as Zek na Gumerta, Bidana Jegola and kesa Chewsa in the Banaja district of the Awi Zone, Amhara regional state. This design would employ multiple sources of data such as distribution of questionnaires and conducting interviews with the concerned parties. The target population for this study was 25 rural kebeles, from those kebeles I selected three kebeles according to the homogeneity characteristics in plantation of Acacia decurrens tree. To determine the required sample size, the selected kebeles has 678 households’ farmers, 105 sample farmers are represented. Then, 35 sample farmers from each kebeles are selected by random sampling method. One-sample t-test analysis was made using Statistical Package for Social Sciences (SPSS) software version 20 to show the result of study. The result discussed by the use of the descriptive and econometric analysis.

  • The Nile Basin Cooperative Framework

    The study focuses on the Nile Basin cooperative framework of the Ethiopia. Nile Basin countries are Burundi, Kenya, Rwanda, Tanzania, Uganda, Ethiopia, Eritrea, Egypt, North and newly independent South Sudan. The riparian countries of the region can be known into upstream and downstream countries. Upstream groups are Burundi, the Democratic Republic of Congo, Eritrea, Ethiopia, Kenya, Rwanda, Tanzania and Uganda. The three downstream countries consist of Egypt, North Sudan and newly independent South Sudan. The downstream states especially Egypt used colonial agreements as instrument to utilize more water from Nile River. The use of colonial agreements and relatively weak positions of Ethiopia in the upstream was one of the obstacles to look optimistic at the possibilities for cooperation and smooth relationships of the Nile Basin countries. After collapse of colonialism, the positive interest of Ethiopia and the establishment of Nile Basin Initiative brought cooperative framework among the Nile Basin countries.

  • Dynamics of Norway’s Dual Citizenship Discourse: Challenges and Prospects for African Immigrants’ Integration and Political Engagement

    The unique principle of citizenship that enhances the possession of single citizenship, has long been the ideal of nationality laws. Yet, interest in dual citizenship has increased, triggered by the success of globalization and a gap in the ideal and reality of the principle of single citizenship. This article, therefore, offers an overview of Norway’s dual citizenship policy and the associated opportunities and risks for African immigrants inclusion. It incorporates facts and arguments for sociopolitical deliberation in an area where emotional reactions abound. Data were drawn from semi-structured interviews and analysis of policy documents. The findings demonstrate that allowing dual citizenship activates the prospects for better integration of immigrants in mainstream society. However, dual citizens can be denaturalized if their actions significantly harm the interests or image of the state. In this way, the policy constitutes a robust impetus toward standardization and normalization of practices that challenge social integration relations. These heuristics are particularly pernicious to immigrants, the casualties of this discourse, because the authorities are aware of a minimal backlash, considering their limited power to fight back politically. Moreover, a major obstacle in the naturalization of immigrants has been removed. This in turn have positive implications for greater identification of migrants with the country of residence, as well as better economic and sociopolitical participation.

  • Abrasion Resistance of Thermally Treated Beech Wood

    The study focused on the abrasion resistance of beech wood thermally treated at high temperatures. A standard test for determining abradability, according to ISO 4649, was used. We studied factors such as the anatomical direction, temperature of treatment, and duration of treatment, as well as their effects on abrasion resistance performance. Four temperature levels (20 °C, 160 °C, 180 °C, and 200 °C) and three durations of treatment (1 h, 3 h, and 5 h) were used. Results showed that the anatomical direction was not a significant factor, but there was a strong influence of temperature and duration of treatment, respectively, on abrasion resistance. Due to a strong correlation between moisture content and abrasion resistance, the equilibrium moisture content of thermally treated wood could be used for the prediction of abrasion resistance

  • Human Rights Violation of the Elderly People in Bangladesh: Do They Enjoy Basic Needs?

    Basic needs are the fundamental human rights recognized by national and international law. This study is an attempt to reveal the picture of human rights violations of the elderly people in Bangladesh focusing particularly on the deprivation of the basic needs of the aged people. In this study, data have been collected from both primary and secondary sources. It reviews the right to basic needs, such as adequate food, clothes, shelter, healthcare, and education. As a human being, everybody deserves these basic needs as fundamental human rights and it is a fundamental responsibility of the state to secure these rights according to the constitution of Bangladesh, Article 15(a). But the study found that these basic rights are not implemented properly in the case of elderly people of the study area. Lacks of moral education and humanity have been identified as mainly responsible hindrances in this sphere. Corruption and poverty are also strong impediments in this regard. The paper proposes some workable suggestions. The government, responsible institutions, and concerned families should come forward to ensure proper education, to ensure proper and sound socialization with native culture, and to raise far-reaching consciousness regarding the welfare of elderly people.


    Introduction: One of the most common foot fractures, fracture calcaneum, whenever has displacement of articular surface, is treated operatively. Various modes of treatment are used for the same. Non operative treatment in severe cases has been associated with poor result. Material and methods: The study included 43 prospective and retrospective cases in 38 patients of intra-articular calcaneal fractures treated operatively with open reduction and internal fixation with locking plate using the standard lateral approach. The patients were assessed radiologically and for functional outcome as per AOFAS (American Orthopedic Foot and Ankle Score) score. Results: 43 fractures in 38 patients were included in our study between19 to 62 years of age with mean age in our study between 38.53±11.17. 79% patients were males and 21% were females. Sander’s type of fracture pattern affected the complications following surgery. There was no influence of complications following surgery over final AOFAS score. Conclusion: Careful patient selection, preoperative planning, appropriate timing for surgery, proper approach for raising full thickness flaps and accurate anatomic reduction gives a good functional outcome.

  • Numerical Simulation of Hole Distribution Blasting with Different Distribution Forms

    According to the vibration of cut blasting, the number of holes and the location of holes are reasonably designed by using finite element software LS-DYNA. The rectangular holes and hollow holes in straight cut are simulated respectively. Of the hole in the straight-cut undercut blasting vibration law. The analysis shows that the larger the diameter of the hole is, the better the vibration reduction is. The more the number of holes is, the more obvious the damping effect is. The best blasting effect of the large diameter hollow hole and the large diameter rectangular hole is 0.93cm/s Reduce the blasting vibration speed, buffered the blasting time; get both a good blasting effect and effective rapid damping effect.
