Introdution: Intussusception is defined as the telescoping of a segment of the gastrointestinal tract into an adjacent one. Pancreatic heterotopia is defined as the presence, outside its usual location, of pancreatic tissue which lacks anatomical and vascular continuity with the pancreas proper. Ectopic pancreatic tissue may be found throughout the entire gastrointestinal track and is often asymptomatic. Surgical excision is potentially curative for EP. Case Report: A 34 years old male presented with severe abdominal pain and distension, intermittent vomiting, not relieved with medications. The sign, symptoms and USG suggested intestinal obstruction. Exploratory laprotomy was done, intussusceptions was reduced. An ileal loop was found to be the cause of intussusceptions which was removed along with small segment of adjacent bowel and sent for the histological examination revealed a presence of pancreatic tissue within lipomatous polyp made up of pancreatic acini and dialated ducts. Conclusion: Ectopic pancreas is a rare condition that lead to ileal intussusception. Despite the development of modern diagnostic modalities, its diagnosis continues to be a challenging one. It is often diagnosed incidentally on histopathological examination and should be considered in differential diagnosis of intestinal mass lesions.

Lumbar disc disease is drying out of the spongy interior matrix of an intervertebral disc in the spine. Lumbar disc disease to encompass several different causes of back pain or sciatica term use by many physicians and back pain researchers. It is thought that about one-third of all back pain lumbar disc disease causes. Pain, loss of muscle strength, and loss of touch sensation may occur if this herniation causes the compression of the most proximal part of the nerve closely neighboring the intervertebral disc material. Pain usually is in the distribution of the nerve compressed, down the back of the leg, side of the calf, and inside of the foot which call sciatica. Most commonly, the nerve root between the fourth and fifth lumbar vertebrae or between the fifth lumbar vertebra and first sacral segment have impinged. Adults frequently experience back discomfort and sciatica. These result in a significant reduction in working hours, as well as financial losses for both individuals and the country. To treat these patients, a thorough examination is required. Inadequate treatment, whether medical or surgical, can have serious consequences, make the suffering worse. This case study was initiated in Suo Xi Hospital Limited,Shantinagar, Dhaka. A 43 years old female patient was visited in the clinic complaining of low back discomfort that has been spreading down her left leg for the past two months.

Published: April 2022

Aortic thrombosis of the newborn is a rare condition associated with poor functional and vital prognosis. Most cases are related to umbilical arterial catheterization, but other risk factors include sepsis, extreme prematurity, asphyxia and prothrombotic conditions. We present a case of neonatal aortic thrombosis presenting with a lower limb ischemia occurring at the second week after birth in association with respiratory distress. Its imaging features are displayed along with a literature review. The Doppler ultrasonography made the initial diagnosis and Contrast Enhanced Computed Tomography provided precise location and extension of the thrombus. In Conclusion, Doppler Ultrasonography is first-line examination for diagnosis of aortic thrombosis in neonates. However, its lack of anatomic precision makes the Contrast Enhanced Computed tomography the imaging technique of choice in investigation of ischemia due to aortic thrombosis, as it provides the topography and extension of the thrombosis, also identifies the ischemic phenomena of abdominal organs and limbs.

Taxpayers' awareness varies greatly in their knowledge of tax requirements, their capacity to learn about their responsibilities, their perception of the consequences of not fulfilling those responsibilities and their awareness of services to help them with their taxes. Empirical evidence suggests that individuals are motivated by financial considerations, non-financial considerations, considerations, information and the way they process this information. The purpose of this study was to measure how much or concern the people of South Sumatra in complying with tax regulations.  This research is a literature study in which the author examines several journals related to previous research. The results of the literature study are then used to identify the level of tax compliance following some steps that can be taken to improve tax compliance in Indonesia. There are three paradigms of tax administration that emerged from this study. This paradigm begins with a government compliance strategy based on detection and punishment. The second paradigm, the paradigm that recognizes the influence of enforcement as well as the administration of taxation that facilitates and provides services to taxpayer citizens, the third paradigm that views taxpayers as members of a larger group, as social beings whose behavior depends on their own moral values and also on their perception of the quality, credibility, and reliability of tax administration. Strategies for controlling tax avoidance fall into three main categories. First, there is room for improvement in policies to improve detection and punishment. Second, there is room for improvement of tax administration services by becoming more consumer friendly. Third, by using mass media to strengthen tax compliance.

Высокий уровень цивилизации, интенсивность производственных процессов, усиливающийся поток информации сказываются на всех областях деятельности человека. Известно, что даже физиологически протекающая беременность оказывает определенное влияние на психику женщины, а некоторые авторы рассматривают ее даже как кризисную ситуацию [1, 2]. Описаны психологические реакции при физиологическом течении беременности. Некоторые беременные особенно уязвимы для воздействия психо-травмирующнх факторов, причем вследствие переоценки прежней системы отношений наблюдается психотравматизация теми конфликтными ситуациями, которые в прошлом не были для нее актуальными. До настоящего времени отсутствуют сведения о влиянии различных факторов на развитие непсихотических расстройств в генерационный период, о динамике развития психических заболеваний в различные триместры беременности. Недостаточно разработана систематизация нозологических и донозологи-ческих психопатологических состояний у данного контингента. Беремен-ность является особым этапом в жизни женщины, во время которого формируются бинарные образования "мать-плод". Особенно уязвимым в данной системе является нейрогуморальное звено [3, 4]. В этот период психосоматическое состояние женщины неразрывно связано с потенциальным здоровьем ребенка.

Published: April 2022

Kriptovalyuta, məlumatları şifrələmək üçün riyazi tənliklərdən istifadə edilən rəqəmsal bir valyuta formasıdır. Bu tip valyutalar son 5 il ərzində dünya miqyasında əhəmmiyyətli dərəcədə populyarlaşmağa başlamışdır. Son dövrlərdə artıq kriptovalyutalardan ödəniş üsulu və mübadilə vasitəsi kimi istifadə olunmağa başlamansı kriptovalyutaların daha geniş şəkildə yayılmasına gətirib çıxarmış və bunun nəticəsində insanların kriptovalyutalara marağının artmasına səbəb olmuşdur. Valyuta əsrlər boyu cəmiyyətin bir hissəsi olmuş, texnologiyanın inkişaf etməsi ilə bərabər öz inkişaf yolunu həyata keçirmişdir. Texnoloji yeniliklərin cərəyan etdiyi bir dövrdə pul anlayışı getdikcə daha da rəqəmsallaşmağa başlamışdır. Keçən əsrin ortalarında insanlar və dövlətlər kağız əskinasları və sikkələr kimi fiziki varlığı olan valyuta vasitələrindən istifadə etmələrinə baxmayaraq, modern dünyada artıq bu tendensiya Debit və Kredit kartlardan istifadə ilə əvəzlənmiş və hər keçən gün daha da rəqəmsallaşmağa başlamışdır. Cəmiyyətlərin 21-ci əsrdə maddi varlığı olan bir valyuta vasitəsindən qeyri-maddi varlığı olan valyuta növünə keçməsi sürətlə yayılmağa başlamışdır. Artıq plastik kartların daha əlçatan olması, ənənəvi valyutaların itirilmə və zərərgörmə və.s bədbəxt hadisələrə qarşı daha davamsız olmağı bütövlüklə rəqəmsallaşmaya gətirib çıxarmışdır. Aktiv sinifləri arasında Bitcoin kriptovalyutasının digər aktiv siniflərinə nisbətdə daha volatil olması bütün valyuta istifadəçiləri tərəfindən anlaşılmaqdadır. Bu kripovalyuta növünün özünə məxsus dəyişkən qiymət tarixçəsi mövcuddur ki, bu volatilliyin araşdırılması özlüyündə böyük əhəmiyyət kəsb edir. Bitcoin kriptovalyutasının 2009-cu ildən sonra ilk gözəçarpan qiymət artımı 2010-cu ildə baş vermişdir ki, bu zaman onun bir qəpiyə bərəbər olan dəyəri artıq 0.09 ABŞ dolları səddini test etmişdir.

IMPROVING THE EFFICIENCY OF THE STABILIZATION COLUMNS IN OIL AND GAS PROCESSING
Authors: Natig Abbasov Natig Abbasov , Rufet Ezizli Rufet Ezizli
Published: April 2022

Rectification process is widely used in oil and gas processing and petrochemistry. The composition of the bottom product of the rectification column usually differs from the equilibrium composition due to significantly higher content of light components or fractions. This stipulates a necessity to include into the technological schemes of several oil refining processes a stabilization unit that are meant to ensure separation of gases and liquid products. A highly relevant task is to explore new possibilities for improving the stabilization process. The aim of the present work was to improve the stabilization process by changing the operating pressure. It was found that increasing the pressure in the stabilization column enhanced the sharpness of separation of butanes from pentanes, which resulted in improving the quality of the products. The experimental-industrial runs confirmed the possibility of increasing the efficiency of stabilization columns in various processes by increasing the pressure within acceptable limits.
Keywords: rectification process, sharpness of separation, stabilization column, pressure.

Review of the Past, Current, and the Future Trend of the Climate Change and its Impact in Uganda
Authors: Nuwagira Upton , Yasin Igga
Published: April 2022

Climate change is a big problem in Sub-Saharan Africa because it brings about prolonged droughts and heavy rainfall that destroys crops. Further, heavy rainfall amounts throughout the entire region have caused flooding and landslides, thus leaving many houses destroyed and people and animals dead. However, the past, current, and future trends of climate change and its impact in Uganda remain unachieved. In this paper, we: 1) analyse the past, current, and future climate change in Uganda; 2) determine the relationship between climate variables; and 3) review the impact of climate change in Uganda. Our study employed the use of secondary data from authentic sources such as the National Aeronautics and Space Administration, journal articles, and books. We used Inverse Distance Weighing interpolation to show the trend of climate change in Uganda. We employed the PCA to show the variation between climate variables in different regions in Uganda. Our data shows that the mean ± SD of temperature (25.24±3.85), rainfall (1252.5±476.9), relative humidity (63.45±7.11), and solar (19.831±1.46) from 1982 to 2019. One Way ANOVA showed a significant difference between temperature (p = 0.003), relative humidity (p = 0.00), and solar radiation (p = 0.00), while rainfall did not vary between regions (p = 0.239). Our study evidences that the current climate change impacts in Uganda include prolonged drought, which causes water stress and increases crop loss, floods, landslides, invasion of locusts, rises in lake water levels, and floating islands on Lake Victoria.

Published: April 2022

A new diving beetle, Copelatus mkambati sp. nov., is described from the Mkambati
Nature Reserve in the Eastern Cape Province, South Africa. The new species is compared with other Afrotropical taxa with two elytral striae and no submarginal stria (the macellus species group of Copelatus Erichson, 1832). A combination of small eyes, rather weak pigmentation, flattened, subparallel habitus, relatively large head and collecting circumstances all suggest that the new species may be semisubterranean in lifestyle.

Published: April 2022

Bu çalışmada açılan ve kapanan şirket sayıları ile muhasebe meslek mensubu olarak çalışanların sayıları arasındaki uzun dönemli ilişki araştırılmıştır. Çalışma kapsamında oluşturulan veri seti toplamda 71 birimlik (71 İl) yatay kesit boyutuna ve 11 dönemlik (2010¬¬- 2020) zaman boyutuna ve her seri için toplamda 781 gözlem değerine sahip bir panel veri setidir. TÜRMOB’un il düzeyinde odasının bulunmadığı 10 il (Ağrı, Ardahan, Bayburt, Bingöl, Hakkâri, Iğdır, Kilis, Siirt, Şırnak, Tunceli) çalışma kapsamı dışarısında bırakılmıştır. Seriler arasındaki yatay kesit bağımlılığı Pesaran (2004) tarafından geliştirilen CD testiyle kontrol edilmiştir. Serilere ilişkin homojenlik/heterojenlik durumları Pesaran ve Yagamata (2008) delta (Δ ̃) ve düzeltilmiş delta (Δ ̃_adj) testleriyle incelenmiştir. Serilerin durağanlık durumları, Pesaran (2007) tarafından geliştirilen Cross-sectionally Augmented Dickey Fuller (CADF) testi ile analiz edilmiştir. Son olarak ise seriler arasındaki uzun dönemli ilişki Westerlund ve Edgerton (2007) Panel Lagrange Multiplier (LM) testiyle incelenmiştir. Çalışmanın sonuçlarına göre incelenen serilerde yatay kesit bağımlılığının olduğu ve serilerin tamamının heterojen yapıda oldukları görülürken, elde edilen Westerlund ve Edgerton panel eşbütünleşme testi sonuçlarına göre ise serilerin eş bütünleşik yapıda oldukları daha açık bir ifade ile uzun dönemde beraber hareket ettikleri görülmüştür.
Küreselleşmenin Yoksulluk Üzerine Etkisi: Türkiye Örneği
Authors: ERSOY Gökhan , KARŞIYAKALI Başak
Published: April 2022

Küreselleşme sürecinin etki alanın genişlemesi 1980 sonrası uygulanan neo-liberal politikalar ile birlikte olmuştur. Taşımacılığın gelişmesi, iletişim, elektronik, internet, ulaşım gibi bilgi ve iletişim teknolojilerinin yaygınlaşması, bilgiye erişimin kolay hale gelmesi ve bu hizmetlerin ucuzlaması, hizmet sektörünün dünya genelinde öne çıkarak ekonomik hasılanın önemli bir bileşeni haline gelmesine neden olmuştur. Bu durum mali piyasalarda sermaye hareketliliğinin artmasına, bankacılık ve finans piyasalarının derinleşmesine ve gelişmesine katkı sağlamış ancak beraberinde getirdiği krizler ve şoklar ile ekonomilerin daha hassas hale gelmesine neden olmuştur. Yaşanan bu süreç ile birlikte yoksulluk çok sayıda insanı etkiler hale gelmiş ve zengin kesim ile yoksul kesim arasındaki gelir eşitsizliği giderek artırmıştır. Küreselleşmenin yoksulluk üzerindeki etkileri iktisat yazınında sıkça ele alınan bir konudur. Ancak literatür incelendiğinde elde edilen sonuçların aynı olmadığı izlenmektedir. Kimi yazarların iddiaları küreselleşmenin yoksulluğu azalttığı yönündeyken, kimi yazarlar aksini savunmaktadır. Bu çalışmanın amacı, Türkiye’de 1980-2018 yılları arasında KOF küreselleşme endeksinin alt bileşenleri olan ekonomik küreselleşme, politik küreselleşme ve sosyal küreselleşme ile doğrudan yabancı yatırımların, yoksulluk (kişi başına hane halkı nihai tüketim harcaması) üzerindeki etkisini zaman serisi ekonometrisinden yararlanarak araştırmaktır. Bu amaçla çalışmada ilk olarak birim kök testleri yapılarak serilerin durağanlığının tespit edilmiş ve sonra Gregory-Hansen eşbütünleşme testi ile iki aşamalı Engle-Granger eşbütünleşme testleri yapılmıştır. Zaman serisi analizinden elde edilen bulgulara göre politik küreselleşme yoksulluğu etkilememektedir. Buna karşın DYY ve sosyal küreselleşme yoksulluğu azaltırken, ekonomik küreselleşme ise yoksulluğu arttırmaktadır.

Background: COVID-19 infection displays a highly heterogeneous spectrum of severities. Laboratory findings are pivotal cues to assess disease severity and aid in retarding/ reversing disease progression. This study aims to identify the haematological, biochemical, and immunological specifics of COVID-19 patients with varying severity and associated comorbidities. Methods: This retrospective study recruited a total of 192 RT PCR confirmed COVID-19 patients. Data on laboratory findings, clinical characteristics, treatment, and hospital stay were obtained and analysed. Results: The patients were grouped into mild, moderate, and severe categories based on disease severity. 96 patients had mild disease, 31 were classified as having moderate COVID-19, and 67 patients had severe COVID-19. 39.58% of the patients were females. The overall death rate among admitted COVID-19 patients is observed to be 19.02%, sepsis and multi-organ failure as the most common cause. The variation in laboratory variables and comorbidities as CAD, CKD, HTN, DM strongly correlate with the severity and increases with the age factor. Pre-existing chronic liver disease emerged to be a comorbidity of significance for acquiring severe COVID-19. Conclusion: Presence of comorbidities, advanced age and male sex emerged as important risk factors while derangements in thrombo-inflammatory markers and haematological indices might be crucial predictors of disease progression. Thromboembolism or superinfection induced sepsis, and multi-organ failure emerged as leading contributors to mortality. High-risk patterns in thrombo inflammatory and immunohematological markers allow for early detection of the disease progression and aid in the institution of personalized intensive therapeutic interventions and monitoring to avoid further deaths.

Published: April 2022

Debris flows remained the deadliest and disastrous geological disasters in Malaysia. The two-decade records from 1995 until 2015 highlighted at least 23 events have occurred regardless of fatalities, and locations. The fatal event was induced by a typhoon recorded in Keningau, Sabah in 1996 with the highest human losses of 302, and economic losses of RM 458.9 million. To date, Malaysia has no dedicated national policy, framework, and standard operating procedure to address this sediment-related disaster in a holistic manner. Moreover, a dedicated, responsible government agency for managing debris flow risk reduction remained elusive. This study aims at providing insights for debris flow disaster risk reduction (DRR) by addressing risk governance, including multi-sectoral agencies roles and responsibilities for different triggering factors, i.e., earthquakes, and intense and prolonged rainfall, and DRR investment towards co-developing an integrated national action plan for reducing current risk, preventing future risk, and strengthening resilience. This study explores various methods to better understand local profiles and suitable methods to assess geological hazard risk processes, activities and impact towards redefining a comprehensive risk assessment method in Malaysia. A case study of recent event in Mesilau watershed induced by the earthquake and rainfall, as a result of 2015 Sabah Earthquake was selected for this study. This study elaborates the significance uses of scientific- and social-based study in promoting science-policy and multi-stakeholders action planning for reducing sediment-based disaster risk in the near future. This includes: (i) the mapping and characterizing the watershed area, (ii) modelling the past debris flow event, and (iii) engaging with the community and stakeholder to gather more local inputs.
