Blizzard phenomena is a complex atmospheric event, in which the snow that falls or has fallen is blown away by the wind, so that the visibility decrease significant enough and the assessment of the simultaneous snow fall is impossible (Țîșlea, D. et al. 1965). The region of Oltenia is featured by a climate with Mediterranean influences, with the dominance of northwest and east winds (Roșu, Al. Et al. 1971). The contact between the cold and the warm air masses leads to the increase of the horizontal baric gradient, which causes strong wind intensification. Due to the geographical position of the Carpathian chain, the penetration of colder and denser air is directed towards the east and the south of Romania, thereby has an impact on the study area (***Climate of Romania 2008). Out of all the natural phenomena during the cold season, blizzard is by far the most versatile, with a heavily impact on society and environment (Teodoreanu 2004). The purpose of this paper is to emphasize the hydro meteorological outcome of the 2018 blizzard episode from February 24#$ to March 2%&. In order to achieve this, we will identify the spatial and temporal variability of the hazard in the region of Oltenia, the atmospheric mechanism of this late blizzard occurrence, its climatic characteristics and the consequences on the rivers runoff regime. We will analyze the synoptic conditions under which the blizzard appeared, the recorded meteorological data and a series of hydrological data from the stations located on the main rivers (Jiu, Olt and Danube) in order to determine the synoptic weather pattern, the successive number of days with blizzard, the dominant direction and the average and maximum wind speed, the average and maximum amount of precipitation, as well as for the thickness of snow layer and the daily liquid levels and flows.

Due to climate change, important attention was paid to the precipitations amounts over Moldavia's northern part. To point out the rainy air-circulation types was used the ‘Hess-Brezowsy’ Grosswetterlagen system (HBGWL) with 29 types of classifying European synoptic regimes of the 2000 to 2018 period at the reference weather stations of Bacău (184 m), Botoșani (161 m), Ceahlău-Toaca (1897 m), Iași (102 m), and Suceava (350 m). The highest amounts of precipitations annually from 2000 to 2018 in Romania's northeastern part were associated with the retrogressive cyclones. Therefore, on a background of the northeastern, cyclonic type (NEZ), there were recorded 53.45 mm, followed by High Scandinavia-Iceland, the ridge over Central Europe (HNFA), with 48.14 mm, and those from East in cyclonic type, with 44.03 mm. All the high over Central Europe (HM) weather types were associated with the lowest precipitations, only 1.71 mm. Also, small amounts of precipitations in the southwestern and south background, both of them into an anti-cyclonic type (SWA, SA), with 2.56 mm, respectively, 2.92 mm. Semestrial, the most important amounts of precipitations in the northeastern part of Romania were attributed to the retrogressive cyclones in the Eastern part of Romania and the ridges over the northern part of Europe. So, associated with EZ, during the 2000 to 2018 period, in the cold semester were recorded 28.43 mm and 27.66 mm within NEZ. During the warm semester, the highest amounts of precipitations were recorded within the HNFA type, with 42.75 mm, followed by Highs over the British Isles (HB) – 25.44 mm. The lowest values were associated with the southerly and southwesterly, both into an anti-cyclonic type (SA, SWA).

In the recent decades, droughts and dry episodes throughout a year have become common for both arid and humid regions. The Carpathian Mountains referred to as natural water towers are also the case. Accordingly, the study aims and distinguishing monthly and daily patterns and peculiarities of precipitation shortage in the high-mountain areas (above 1000 m) of the Polish and the Ukrainian Carpathians using monthly and daily data series (1984-2015) of weather stations Kasprowy Wierch (1991 m a.s.l), Dolina Pięciu Stawów (1670 m a.s.l) and Morskie Oko (1408 m a.s.l) in the Polish Carpathians, Play (1343 m a.s.l) and Pogegevskaya (1429 m a.s.l) in the Ukrainian Carpathians. Here, in all the months throughout a year, dry episodes have been detected. In the Polish Carpathians, represented by three measuring stations, the driest episodes in the years took place from August to October and January, and slightly less – about 11-16% in the remaining months. In the monthly context, the highest frequency of dry months, exceeding 20%, is detected in June both in Pogegevskaya, as well and in April and July in Play. In March, April, as well as November extreme atmospheric drought took place in the entire area of the Polish Tatra Mountains, the highest mountain range of the Polish Carpathians. In all the measuring stations of the area in November 2011, the precipitation amount did not exceed 11 mm. They accounted for less than 10% of the average multiannual precipitation sum. Alongside, the positive trend in the years from 1984 to 2015 with significance levels of 0.1 and 0.2 was only established in the lowest monthly precipitation sums at Pogegevskaya. The longest episodes without precipitation, periods that begin and end with a day without precipitation, are detected in most parts of the study area in October and November 2011, especially in the western and southern parts of the Polish Carpathians.

Floods are one of the biggest natural disasters, causing significant economic and human losses. Regardless of the degree of development of urban or rural systems, floods account for about a third of all-natural disasters globally. Identifying areas vulnerable to floods is essential for better management and mitigation of their effects. The research aims to identify areas vulnerable to floods in the city of Codlea, Brașov County. Annually, the city records significant floods, one of the determining factors being its location, near the southern slope of the Perșani Mountains. The research proposes the Flash Flood Potential Index (FFPI) computation by combining GIS techniques with the Frequency Ration bivariate statistical model. The correlation of various flash-flood conditioning variables allowed us to compute the FFPI. The methodological approach could represent an essential tool for local authorities for better flood risk management.

Determination of the fluctuations in groundwater level (GWL) in terms of planning and operating their resources is important. In Turkey, many basins are experiencing problems in terms of the potential of groundwater. Increasing water demand, adverse conditions created by climate change and lack of planning related to underground water management in the basin have increased these problems. As a field of application, it was applied for General Directorate of State Hydraulic Works (DSI) well of Hatay province in Turkey. In the study, GWL predictions were evaluated using data mining approaches such as Radial Basis Neural Network (RBNN) and Support Vector Machines (SVM) methods. Monthly data sets between 2002 and 2015, including hydrological parameters predict the GWL used. According to comparison results, it was observed that the data mining models gave good results for observation in test phase.

Large dams, as well as conventional hydrotechnical constructions with the role of breaking the drainage slope (waterfalls or bottom sills), flood mitigation or with the role of protection against floods (shore defences) have a profound impact on the environment. Due to these constructions, the ecosystems on the Bistrița Ardeleană river have undergone changes or even established new ones. This paper wants to highlight the morphological changes of the Bistriţa riverbed by analysing the transversal profiles made between 1972 and 2015. The profiles were made in the flow measurement section at two hydrometric stations, one being located in the upstream part of the river basin and the other before the Bistrița river flows into the Șieu river. By comparing the results obtained from the profiles made before the Colibița hydrotechnical system was started or completed with the data obtained from the profiles after the commissioning of the Colibița hydropower plant, we managed to highlight that the Bistrița Ardeleană riverbed registered several negative effects in terms of morphologically both vertically and horizontally. We also found that the riverbed downstream of the dam there is a phenomenon called hydraulic paving.

Due to climate change, extreme rainfall is more frequent, and the phenomenon of drought and desertification in some parts of the world is accentuated. Scientists forecast that these trends to continue as the planet continue to warm. An increasingly common phenomenon is the occurrence of flash floods in areas where human intervention on natural conditions has been significant. Over this intervention is superimposed the modification of the characteristics of extreme rainfalls (duration, intensity, height), resulting a series of negative consequences on the ecosystems of the watersheds. For their protection, a more accurate forecast of the size and times of occurrence of the maximum water flows and levels in different sections are needed. This forecast must be made with appropriate methods, such as the use of advanced hydroinformatic tools. This paper analyses the influence of rainfall characteristics on runoff in a small watershed, using rainfall-runoff phenomenon modelling. The modelling is realized using advanced hydroinformatic tool MIKE11, developed by Danish Hydraulic Institute (DHI).

The study aims to analyze and compare the mean sea level pressure field to show the changes in the breeze regime in the coastal area of Romania in the current climate and the one projected in climate scenarios. The mechanism and variability of the breeze cell (intensity, location, frequency, persistence) are analyzed and compared for extreme conditions of warmest summers (July) during the two climatic intervals: 1971- 2000 respectively for the RCP4.5 2021-2050 scenario. The high-resolution climate is simulated using the RegCMv4.5 regional climate model at 5 km resolution, coupled with the global EC-Earth model. These dynamical downscaling methods were performed for the first time for Romania in ANM (Meteo Romania) during the AZURE-Microsoft project (2018), aiming to refine the scale of the global climate scenarios to allow process analysis. The mechanism of changes is analyzed with the interaction between regional-scale conditions and large-scale dynamic factors. The results indicate changes in the frequency of intense events and the spatial development of the breeze cell, with a time-mean intensification of both sea and land breezes and, a greater spatial advance in the area mainly during the day. Large scale-dynamics changes in interaction with the breeze circulation lead to an anticyclonic rotation under a warmer climate of the coupled circulation that induces a shift to the South-West of the cell, with a possible impact on the location of the associated precipitation. Regarding timing, a time-delay in the sea breeze occurrence (smaller pressure gradients persist longer due to warmer sea surface temperature), together with enhanced cell intensity, later on, makes the event appear as a more abrupt or extreme one. The results of the study provide potentially important input for further analysis of projected impacts of the breeze circulation on the regional climate.

The paper presents and analyzes the variations of meteorological and specific snow parameters which favored the onset of avalanches in the winter season 2019-2020 in the mountains monitored by the Snow and Avalanche Program of the National Meteorological Administration, taking also into account the estimated avalanche risks for each massif. The analyzed parameters are those measured during the daily observations and weekly measurements at the meteorological stations Bâlea-Lac, Vârful Omu, Sinaia, Predeal, Parâng, Țarcu, Semenic, Vlădeasa, Iezer, Călimani, Ceahlău, as well as during some measurement campaigns outside the meteorological stations area. Avalanche cases and favorable conditions for their triggering are included in a database, to be analyzed and used to better estimate the avalanche risk and reduce their effects on the environment and people. The favorable conditions for triggering the avalanches were due to both significant snowfall, high temperature values or their sudden increase, as well as the transformations that take place inside the snow layer, as a result of which unstable structures are formed.

The OBJECTIVE was to create a simulator for practicing manual skills of performing percutaneous endoscopic gastrostomy (PEG).METHODS AND MATERIALS. A patient simulator has been developed. It has a mouth, oropharynx, removable esophagus, stomach, and anterior abdominal wall that allows performing all stages of the operation. To objectify tension force of the gastrostomy tube during fixation and transmitting the proper manual sensations, a measuring device – bezmen was used. Initially, we used a single-use gastrostomy kit Freka PEG, FR 20 for the simulation. It increased the cost of the simulation. Therefore, instead of disposable kits, the Pezzer catheter No. 24 with a developed metal coneshaped tip was used as a gastrostomy tube (patent RU 2669483, 11.10.2018). Simulation was performed with reusable surgical instruments. At the final stage, an additional external pressure plate and a connector with a cover were used.RESULTS. The developed method of simulation training for PEG imposition allows performing all stages of endoscopic gastrostomy imposition. The simplicity of manufacturing and the possibility of replacing worn elements allows multiple implementation of the method. Using reusable instruments and a Pezzer catheter with a designed reusable tip increases the cost-effectiveness of training. The use of a measuring device allows to convey the necessary sensations of tension of the gastrostomy tube during fixation with an external pressure plate, corresponding to the sensations in real clinical simulation.CONCLUSION. The developed method of training for PEG imposition with the simulator allows to effectively work out manual skills and reduce the risk of iatrogenic complications during surgery on the patient.

Published: April 2021

At present, the determination of the severity of patients with complications of acute calculous cholecystitis, manifested in the form of mechanical jaundice (MJ), remains an insufficiently studied issue. This is due to the fact that the main attention in the examination of such patients is paid to the diagnosis and assessment of the severity of liver failure, and the signs of SIRS (Systemic Inflammatory Response Syndrome) are not given due attention. In this regard, this literature review presents data on the systemic inflammatory response syndrome in such patients, describes its etiopathogenetic mechanisms of development, presents clinical signs, stages of this pathological process. The role of biomarkers, which can be used to determine the severity of inflammatory changes in the biliary system in MJ, is estimated on the basis of literature data.
THEORY OF CREATION OF THE INSURGENT-GUERRILLA LIBERATION ARMY IN THE MILITARY-HISTORICAL WORKS OF OUN MEMBERS
Authors: Lisina Svitlana
Published: April 2021

Summary. The purpose of this research is to study the theoretical works of OUN activists on the creation of an insurgent-guerrilla liberation army, which have not lost their significance for the development of modern Ukraine and the reforming of its Armed Forces. The research methodology is based on the principles of historicism and the synthesis of comparative and problem-chronological methods of researching the works of OUN soldiers on the creation of the Ukrainian army. The scientific novelty lies in the implementation of one of the first attempts at a comprehensive study of OUN propaganda and journalistic materials on military-organizational activities, which clarifies the role of the Organization’s military figures in the formation and development of its basic principles on the eve of World War II. Conclusions. On the basis of the relevant funds of the State Archive of Lviv Region (SALR), memoirs, nationalist newspapers and magazines, fundamental monographs and dissertations, the role of OUN leaders E. Konovalets, M. Kolodzinskyi, O. Gasyn, R. Yaryi, Z. Kossak is covered on the creation of the liberation army in military-historical and military-theoretical works. The main materials, which consider the issues of the coming war, tactics and strategy of Ukrainian nationalists, military doctrine and military training were prepared by: M. Kolodzinskyi ‒ "Ukrainian military doctrine", Z. Kossak ‒ "44 rules of life of the Ukrainian nationalist", R. Yaryi ‒ "Military education of youth", E. Konovalets ‒ "Military Affairs", "Military Training". The creative achievements of OUN military figures were marked by a wide range and depth of thinking, high professionalism. All educational and theoretical developments of OUN soldiers are a source for studying the military-historical thought about the activities of the nationalist organization of 1929‒1939. This legacy can be used in the not yet completed state-building processes of modern Ukraine, the reforming of the Armed Forces of the state, the prospect of our country’s accession to European structures and NATO.

Authors: Nabeel Ahmed Rajab  , Ahmed Mohammed Turki
Published: April 2021

This study evaluated the toxicity of ciprofloxacin to spleen and liver when used for the treatment of mice infected with S. typhi for seven days. The dose concentration used in these experiments was 100mg/kg. Mice were divided into two groups . The first group (negative control) was not given ciprofloxacin, but rather a sterile phosphate buffer solution (PBS) as an alternative. Ciprofloxacin was administered to the second group. After seven days , the animals were sacrificed and organs (liver and spleen) were collected . The histopathological examination showed normal hepatocytes in the liver  and normal structure of  spleen cells in animals of control group . However, the treated group showed dilated and congested blood vessels with perivascular inflammatory cell cuffing and acute cell swelling  in the liver, as well as white pulp activation with an increased number of megakaryocyte cells in the spleen. Therefore, the current study suggests that  the concentration of 100 mg/kg of ciprofloxacin is considered to be toxic to  hepatocytes and splenocytes of mice  during the treatment period.
Relationship Between Orexin-A and Insulin Resistance in Patients with Type 2 Diabetes Mellitus
Authors: Chinar Hameed Sadiq  , Ridha H. Hussein  , Ismail M. Maulood
Published: April 2021

Background: Orexin-A is an orexigenic hormone that plays an important role in the metabolism of blood glucose, insulin, and insulin resistance (IR). The pathogenesis of type 2 diabetes mellitus (T2DM) is related to the abnormality in insulin and IR. However, no sufficient studies to date have clearly shown the association of orexin-A with biochemical parameters related to T2DM.

Objectives: The aim of this study was to determine the relation of orexin-A with IR and how they associate with physiological changes in T2DM patients. Understanding this relation will offer some pharmacological tools to reduce some complications in diabetes.

Materials and Methods: A total of 41 T2DM and 43 non-DM subjects, aged between 40-60 years with body mass index (BMI) ≤25 kg/m2, participated in the present study.

Fasting serum orexin-A, IR, fasting blood glucose (FBG), glycated hemoglobin (HbA1C), lipid profile, liver enzymes (alanine aminotransferase (ALT) and aspartate transaminase (AST)), nitric oxide (NO), and malondialdehyde (MDA) parameters were evaluated. Orexin-A was evaluated by using enzyme-linked immunosorbent assay (ELISA). For statistical analysis, GraphPad Prism 7.0 and SPSS version 24.0 programs were used.

Results: Orexin-A was positively correlated with blood pressure, FBG, HbA1c, insulin, and IR but inversely related to insulin sensitivity (IS), leptin, and gender. Stepwise multiple regression presented HOMA-IR, diastolic blood pressure, and very-low-density lipoprotein-cholesterol as predictors for orexin-A. The area under control value showed orexin-A, FBG, HbA1c, HOMA-IR, IS, ALT, AST, NO and MDA as biomarkers for T2DM disease.

Kampung Batu Busuk, kelurahan Lambung Bukit, Kecamatan Pauh, Kota Padang merupakan salah satu daerah penghasil durian unggul. Namun durian yang ada saat ini merupakan durian alam yang dibudidayakan dengan pemeliharaan yang minim. Tanaman durian juga sudah tua sehingga kurang produktif dan berasal dari perbanyakan biji sehingga kualitas produk tidak seragam. Dengan demikian dibutuhkan transfer teknologi tepat guna yang dapat menyediakan bibit dalam waktu singkat dan cepat, mudah diimplementasikan dengan tingkat keberhasilan yang tinggi. Teknologi sambung mini diharapkan menjadi solusi permasalahan pertanaman durian di Batu Busuk. Kegiatan pendampingan pekebun durian telah dimulai dari tahun 2018 dan berlanjut hingga sekarang. Pembibitan durian dilakukan dari bulan Juli 2019 dan penyerahan bibit kepada masyarakat dilakukan pada Februari 2020. Penyuluhan, demonstrasi plot dan pelatihan digunakan sebagai metode kegiatan transfer teknologi sambung mini kepada masyarakat pekebun durian. Berdasarkan kegiatan yang telah dilakukan, dapat disimpulkan bahwa permasalahan penyediaan bibit untuk peremajaan tanaman durian di Batu Busuk dapat diatasi dengan penyediaan bibit durian sambung mini. Pembibitan durian dengan teknologi sambung mini berhasil dilakukan dan mendapatkan kurang lebih 1100 bibit. Tingkat keberhasilan sambung mini yang dilakukan oleh pekebun durian baru mencapai 43%, mengindikasikan keterampilan berperan penting terhadap tingkat keberhasilan sambung. Hasil evaluasi terhadap pertumbuhan bibit menunjukkan bahwa pekebun durian sebaiknya menggunakan benih berukuran sedang dan besar sebagai sumber bibit untuk batang bawah karena memberikan pertumbuhan yang lebih baik. Teknologi sambung mini pada kegiatan pembibitan durian perlu terus dilakukan secara mandiri dan berkelanjutan dengan menggunakan entres yang berasal dari durian unggul lokal Batu Busuk sendiri dalam rangka pengembangan durian Batu Busuk.

Kelompok Tani Durian Sakek merupakan salah satu kelompok tani yang memelihara ternak kerbau yang di perah susunya untuk dijadikan dadih, terletak di nagari Pematang Panjang, Kabupaten Sijunjung, Sumatera Barat. Ternak kerbau dipelihara secara sederhana dilepas di padang penggembalaan dengan kondisi kualitas pakan rendah sehingga produksi susu yang dihasilkan juga rendah. Hal ini bisa dilakukan dengan pemberian pakan suplemen dengan memanfaatkan sumber daya pakan lokal seperti daun singkong dengan kandungan protein yang tinggi dan banyak tersedia di daerah setempat. Kegiatan ini bertujuan untuk memberikan pengetahuan dalam inovasi teknologi pemanfaatan pakan hijauan lokal khususnya daun singkong sebagai pakan suplemen ternak kerbau untuk meningkatkan produksi susu kerbau sehingga akan meningkatkan pendapatan peternak, sedangkan target khusus diharapkan adalah menumbuhkan swadaya masyarakat dalam usaha pemanfaatan pakan hijauan lokal sebagai pakan ternak. Metode yang diterapkan adalah penyuluhan, pelatihan/percontohan dan diskusi serta bimbingan dan pembinaan. Hasil yang diperoleh dari kegiatan ini produksi susu meningkat 1.05 vs 1.09 liter/hari dan kualitas susu juga meningkat: lemak 5.75 vs 7.46%, Protein 4.05 vs 5.25%, SNF 10.66 vs 11.45%, Total solid 16.39 vs 19.95 dan kadar air 83.60 vs 80.05%. Dari kegiatan ini dapat diambil kesimpulan pemberian daun singkong sebagai pakan suplemen dalam bentuk pellet dapat meningkatkan produksi dan kualitas susu kerbau penghasil dadih, sehingga meningkatkan pendapatan peternak.

Masyarakat Kelurahan Lambung Bukik Kecamatan Pauh Kota Padang mayoritas bermata pencaharian bertani tanaman hortikultura, palawija, tanaman hutan (Sungkai dan gaharu) dan beternak sapi dan ayam. Kelompok Tani Sungkai Permai memiliki pohon gaharu yang telah berumur 2-5 tahun yang mana bibitnya diperoleh melalui kegiatan Elok Nagari CSR PT Semen Padang. Saat ini pohon gaharu tersebut sudah dapat berpotensi baik melalui inokulasi pathogen jamur pada pohon gaharu guna membentuk gubal gaharu yang bernilai ekonomi, maupun pemanfaatan daun menjadi minuman kesehatan. Kegiatan ini bertujuan: 1). masyarakat mengetahui cara budidaya tanaman gaharu, dan mengetahui manfaat dari tanaman ini serta tahu cara mengolah bagian dari pohon gaharu seperti gubal dan daun menjadi bahan baku minuman teh, 2). memberikan keterampilan khusus bagi anggota kelompok tani sehingga diharapkan dapat dijadikan sebagai salah satu usaha mandiri; 3). memberdayakan masyarakat dalam memanfaatkan lahan kosong melalui pola tanam agroforestri tanaman gaharu dengan tanaman perkebunan, 4). sebagai bentuk kegiatan kemasyarakatan dari Universitas Andalas, khususnya Fakultas Pertanian. Kegiatan ini dilaksanakan di kelompok Tani Sungkai Permai Kelurahan Lambung Bukik Kota Padang. Kelompok tani Sungkai Permai telah memperoleh pengetahuan tentang budidaya tanaman gaharu serta pemanfaatan teh melalui metode partisipatif dan pelatihan berupa demonstrasi dan demplot melalui penanaman lebih kurang 150 batang bibit gaharu sebagai bahan baku teh melalui pola agroforestri. Kelompok tani Sungkai Permai telah memperoleh pengetahuan pemanfaatan bagian gaharu menjadi teh gaharu sebagai minuman dan obat kesehatan dari daun dan gubal gaharu. Bahan baku daun dan gubal gaharu yang berasal dari pohon gaharu sekitar lahan petani di kelurahan Limau Manis atau daerah lain dapat dikelola oleh kelompok Tani Sungkai Permai dapat menjadi peluang usaha produktif sebagai teh dan obat dalam bentuk minuman kesehatan untuk meningkatkan perekonomian masyarakat.
