 Hesitancy of Covid-19 Vaccination among Teenagers and Young Adults Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. It is a global pandemic and has led to serious illness and death among all ages and even in younger adults who are otherwise healthy. The best way to prevent and slow down the transmission of this deadly disease is to get vaccinated. As per the CDC teenagers and young adults between the ages of 12 to 24 have the lowest vaccination rate among those eligible to receive a COVID vaccine. We did a survey-based study among high school and college students to find out the reasons for the reluctance of Covid 19 vaccination Covid-19 is a global health pandemic and has caused almost 5.5 million deaths as of January 2022.1 The USA experienced the highest Covid- 19 associated mortality among the world countries. COVID-19 vaccinations played a crucial role in flattening out the number of cases and deaths. Currently, Vaccines from PfizerBioNTech

 Spontaneous Rupture of Subclavian Artery Branch Leads to Compromised Airway Though rare, a spontaneous rupture of a branch of the left subclavian artery leading to a compromised airway requiring emergent intervention by experienced staff can occur. In such cases, the expanding hematoma can cause tracheal deviation. Here we discuss the emergent airway management of such a case emphasizing the importance of early intervention by an experienced airway management team. We present the case of a spontaneous rupture of a branch of the left subclavian artery leading to a compromised airway requiring emergent intervention by experienced staff. Such causes of tracheal deviation are exceedingly rare, though may become more common as people take antiplatelet drugs as a means to prevent pathology induced clots. A non-stridorous 60 year old male with past medical history significant for myocardial infarction and multiple strokes currently taking clopidogrel and rivaroxaban. While intoxicated, he fe

 IFA Utilization and Factors Associated with IFA Utilization Among Pregnant Women Attending ANC at Government Health Facilities and Family Guidance Clinic in Hawassa City, South Ethiopia Background: Iron deficiency is the most common nutritional disorder in the world, and most prevalent in women of reproductive age.

 Hypoglycemia in Non-Diabetic Patient: Report of Two Cases of Insulinoma Background: Insulinoma is a B-cell tumor of the islets of the pancreas with an incidence of 4 per 1 million people per year, which produces excess insulin and can cause symptoms related to hypoglycemia at the level of the central nervous system or symptoms related to excess release of compensatory catecholamines. The presence of hypoglycemia, elevated insulin, proinsulin, and c-peptide levels suggest endogenous hyperinsulinism, which together with imaging findings suggestive of neuroendocrine tumor, allow establishing the diagnostic impression of Insulinoma. Cases report: Patients with neuroglycopenic symptoms, biochemical profile of hypoglycemia, endogenous hyperinsulinemia and radiological finding compatible with insulinoma are reported, who were treated by surgical resection of the tumor, with complete resolution of the initial symptoms. Conclusion: The clinical presentation, diagnosis and treatment of insulino

 Sustaining Tradition and Fulfilling Agreements on Traditional Medicine Since the Alma Ata Conference Introduction: The implementation of traditional medicine strategies and their integration into the mainstream health systems by African governments has been a difficult process since its recommendation at the Alma Ata Conference of 1978. Objective: This paper seeks to review how traditional medicine has survivedand what various African countries have done to implement traditional healthcare strategies and their integration into the national health systems as recommended by the Alma Alta conference of 1978. Methodology: We purposively selected developed, middle income and African countries for the purpose of this review.We reviewed traditional medicine policies and programs in elevenpurposively selected countries from different political and economic blocks. We conducted a review of published works on traditional medicine implementation with more focus on the African continent. We have

 The End of Reality In this article, I argue that in the age of neoliberal (postindustrial) globalization human relations to the environment have been “enframed” by capitalist ideology leading to the end of reality and the rise of human worldviews and ethos based on overconsumption and resource exhaustion as the determinants of existence over and against the environment and nature. Identity politics, the reification and commodification of (serial) identity practices, cultures, and “all of the accoutrements of the economy of spectacle and the manufacturing of images and fetish desires,” on the one hand, and the continuous atomization of the human subject in (neo) liberalism on the other are mechanisms for creating surplus-value and continuing capitalism’s domination over the world in the era of climate change. These two dialectical practices represent two fascist attempts to perpetuate capitalist relations of production and accumulate surplus value amidst its deleterious effects on all

 21st-Century Oil and Gas Industry Research and Practices: New Petro-Geological Teaching The article discusses a new approach to the processes of oil formation. The author offers his own paradigm, or angle of vision into origin and life (space-time dynamics) of an oil and gas play. Special attention is paid to the analysis of risks and uncertainties in the petroleum business. The 21st century has been marked by many unexpected events to humanity in various spheres of life and economics, including oil and gas industry. While petroleum, or crude oil, mean energy source, fuel and raw material (a feedstock) for many industrial needs, upstream oil and gas companies identify, extract, or produce raw materials. Advancements in R&D field of the “petroleum business” have largely been the primary concerns of humanity. About 70,000 oil fields have been discovered in the world, of which 1,500 are large.  As many as 70 countries have proven oil reserves, more than 65 countries produce oil on th

 Experimental Research on Bit Side Force and Anti-deviation in Vertical Well Based on dimensional method, the similarity criterion of simulation test was derived. The experimental apparatus was established in accordance with the similarity criterion. A series of experiments with different drilling parameter were carried out. The experimental results show that with rotary speed rise, the bit side force fluctuation increased, however, the vibration energy at the dominant frequency decreased, at low rotary speed, the dominant frequency of the bit side force is equal to rotation frequency of drill string, and at high rotary speed, the dominant frequency is consistent with the backward whirl frequency of drill string, which is about 3 times of rotation frequency, moreover, as WOB rise, the vibration energy at dominant frequency increased, while the total wave energy decreased, and the critical rotary speed value at the jump process of the dominant frequency increased. Furthermore, for the p

 Study of Optimum Drilling Mud Formula In the work, a study was made of the rheological and physical-mechanical properties of cement grout mixture and grout cements. For a qualitative cementing process, an analysis of cement slurries was carried out with a study of changes in the consistency of cement slurries after a certain time. Thus, the acceleration of the process of drilling observation and production wells depends on the correct selected cement slurry.Oil-based emulsion drilling fluids are divided into two groups - emulsions of the first type and the second - reverse or invert emulsions. If the first hydrocarbon liquid is dissolved, then the latter are represented by dissolved water in the hydrocarbon liquid.1 Thus, depending on what is the dispersed phase and what is the dispersion medium, groups of emulsions are determined. According to the purpose, the solutions are divided into two groups - drilling fluids and special fluids (for work over (work over) and underground well wo

 3D Modeling and Simulation of Subsea Structures Tieback to Floating Production Storage and Offloading (FPSO) Unit for Offshore Field Development This paper seeks to model and simulate a 3D Floating Production Storage and Offloading (FPSO) unit and subsea structures for the separation of reservoir fluids. In this paper, each component on the hull of the FPSO and the subsea structures were constructively designed with Python codes written in Blender software according to ship building practice and offshore standards. Material (colour) was added to each component as well as environmental features to depict reality for deepwater operations with extreme weather conditions. Nanofiltration (NF) membrane separation technology was implemented into the modelling process for the purification of water to reduce the sulphate content for reinjection to boost productivity. Also, this study minimizes flow assurance problems to improve subsea production system (SPS) by installing a subsea separator wh

 Detection of Antibodies against Bovine Brucellosis in ElHawata area, ElGadarif State, Sudan The main objective of this research was to study bovine brucellosis in ElHawata area, ElGadarif State (2007). A total of 121 bovine sera were collected randomly from cattle of different age and breeds. Data regarding the history of the disease (frequent abortion) in the area were recorded. Samples were 1st subjected to serological investigation using Rose Bengal Plate Test (RBPT). Nineteen samples (15.7%) were found positive for antibodies against Brucellosis. The result was confirmed with (competitive ELISA) c-ELISA. The result of both tests was almost identical with one exception (one additional sample was found positive with c-ELISA). Only positive samples were tested with Serum Agglutination Test (SAT). The result confirmed that of c-ELISA and revealed antibody titer ranged between 17-1280. Regardless of age, the disease was detected in all groups, and it was more prevalent in cross breeds.

 Phenology of the Mencía Variety Cultivated in a Territory Included in the UNESCO World Network of Biosphere Reserves The study of grapevine phenology is very useful for vineyard management and control, as it allows the application of phytosanitary treatments at the phenological stages where the crop is most susceptible to different diseases, mainly cryptogamic. This work describes the phenological behaviour of the red Mencía variety, the most common in the Ribeira Sacra Designation of Origin (Northwest Spain), as well as its thermal requirements throughout its vegetative cycle. It has been carried out in a vineyard located in the highest areas of the Sil River canyon, during the year 2021. The observations were made on 10 vines and the phenological scale used was the one standardized by the BBCH. The vegetative cycle, from the beginning of sprouting to the harvest, took 163 days, during which 5097 GDD (Growing Degrees-Days) were accumulated. In agronomic, economic, social, historical,

 Positively Using Heat Island to modify City Environment Heat Island effect was caused by the difference in the effects of the sun heating the urban and suburban region where there are abundant of constructions and plants respectively, and it brought some problems about the living environment for the people. The urban region where there is almost only concrete and iron made constructions became too hot and sometimes unacceptable for people to stay, and the haze is also hard to eliminate by afforestation, haze is significant a risk to people’s health. However, this effect could also be positively used. As the heat island causes temperature gradient between the city center and the suburban area where the afforestation is more abundant, the city could be redesigned as a structure of center-industry and surrounding-living; thereby, not only the region where people live would be cooler and healthier, but also the heat island would be utilized as a huge chimney to extract the industrial poll

 Thoughts Upon a New Way of Viewing Disease Classification While waiting for the furore of my last article (Concepts of Healing) to die down, I came up with a possibly helpful new manner to classify disease categories. I decided to determine if it would be beneficial to classify diseases according to the major body systems involved directly at the site of the infection. At the beginning, I just sorted, grouped and looked for pattern(s). Presented herein is the result of those investigations, according to the body of knowledge known as Peripheral Neuropathy. The medical body of knowledge known as PN has shown us that there are 3 major Enteric Nervous System (ENS) elements that are directly involved in the control and clean up after predation of the body by pathogenic microorganisms. These elements are the nerve cell bodies located directly within the skin, next to the muscles and spread throughout the interior of the body cavity. Please remember that the ENS works directly and very inti
