The variation of river water runoff is a normal phenomenon, given the close link between runoff and atmospheric precipitation, both components of the water balance. The variation of the flow over a period of time can be calculated using several simple and complex indicators, among which the most important are the absolute and relative deviation, the standard deviation (deviation) and the coefficient of variation. In the Căliman Mountains, no analysis of the variation of river water flow has been made so far, this work being the first of its kind. Following this work, it was observed that the variation of water flow from these rivers in the period 1950-2010 depended strongly on the variation of climatic elements (precipitation and temperatures), but also on the characteristics of river basins, both annually and seasonally.

Multiple hazards to human health and the environment are associated with a lacking waste management. Among them, landfill fires suddenly release large amounts of various chemicals, leading to environmental pollution and to potential impacts upon human health in the affected areas. The low level of separate collection and recycling of municipal waste in Romania leads to the accumulation of biowaste and other combustible waste (paper, plastic and textiles) in landfills, increasing the risk of landfill fires. Inventorying and monitoring the effects of such inadvertent events is a necessary step towards a thorough assessment of the environmental pollution at regional level. By using a waste fires database and reviewing press reports on large landfill fires, we have identified the spatial distribution of landfill fires in Romania, between 2016 and 2020. While the national annual average is rather low (around 35 fires per year), we were able to identify several hotspots of frequent landfill fires. Such sites draw attention to the ineffective municipal waste management in Romania and to the need for a better environmental monitoring in areas affected by landfill fires.

Published: April 2022

The Southern Bărăgan Plain is a geographical unit where the rainfall processes have a moderate action, even reduced in some places, taking into account the low rainfall as well as the morphology and morphometers of the relief. These processes have an impact on man and human activities, primarily through the action they have on land on which intensive agriculture is practiced or even on inhabited areas.
FROM A KNIGHT TO A MASS WORKER: THE DEVELOPMENT OF ERNST JÜNGER’S VIEW OF THE FIGHTING INDIVIDUAL
Authors: ŠAJDA Peter
Published: April 2022

In the article I first examine Ernst Jünger’s thematically structured memoir The Fight as Inner Experience in which he depicts the individual soldier as a committed knightly fighter who is willing to sacrifice his life for an idea. Subsequently I analyze Jünger’s treatise Total Mobilization in which a largely different picture of the fighting individual emerges: a conformist member of the working mass who performs unquestioningly tasks assigned to him by the collective. I explain the reasons for “the victory” of the worker over the knight and highlight important shifts in Jünger’s thinking as well as its ambiguities.

Published: April 2022

Background:India has introduced a new COVID-19 vaccine recently which is made primarily available for healthcare workers and frontline workers. Globally, few other vaccines were also been approved against the SARS-CoV-2, whereas only little is known about its acceptance in the community. However, vaccine hesitancy is a public health threat. Therefore, this study was aimed to assess the acceptance of the COVID-19 vaccine and its determinants. Method: A mixed-method design starting with a cross-sectional study using a pre-tested, semi-structured questionnaire between December 2020 – January 2021 among adults (18 years and above) residing in Chengalpattu followed by a qualitative approach with five key informant interviews was planned. Based on previous studies, the sample size was approximated to 140 which was collected through a simple random sampling method. Collected data were analysed using IBM-SPSS, v21.0. Statistical significance was described using the chi-square test, p < 0.05 was considered significant. Results: Among the 140 respondents, the majority 56 (40%) had acceptance of the COVID-19 vaccine while 34 (24.3%) were inconclusive of their decision on vaccine acceptance. The most preferred characteristics of the COVID-19 vaccine felt by those showing willingness to vaccinate were both minimal side effects and cost-effectiveness 24 (42.9%). The majority 33 (58.9%) of the respondent’s decision-making depends on the doctor’s recommendation regarding vaccination. Statistical significance (p < 0.008) was perceived among gender and vaccine acceptance. Conclusion:A large proportion decided to delay vaccination due to increased concern about vaccine side effects reported in various other countries. This concern should be dealt with to develop an effective mass vaccination strategy against the COVID-19 and increase vaccine coverage.

A novel optimal approach for control law of multi-rate systems with different rate operations
Authors: Roosta Alireza , Soltanimehr Alireza
Published: April 2022

The main purpose of this study is to propose a method to achieve optimal response and performance of the multi rate systems in existence of different sampling rates and to avoid data losses in such systems. In this paper, a new approach based on the multi-rate digital system is proposed. Based on this method, we will be able to maintain optimal performance of these systems without losing data, in addition to establishing connections between subsystems with different sampling rates. By the proposed method, not only the effect of different sampling rates in multi-rate systems is ignored, but also, we can connect subsystems with different rate operations without compromising system performance and data loss which simplified system design and sensor selection by the digital system designers. This means the designer can choose any sensor without concerning about the sampling rate and the operation rate of the system and matching them together. Finally, a guided missile with different sampling rates between the seeker, autopilot, guidance law and the output feedback are simulated and its effective performance in pursuit, hitting and smooth motion toward the target in a motion scenario is shown.
Heuristik, Genetischer Algorithmus und andere Zufälligkeiten in der Computerchemie
Authors: Ugi Ivar K. , Heilingbrunner Martin J. , Gruber Bernhard
Published: April 2022

Heuristic procedures have been used increasingly in recent years in synthesis planning, chemometries and combinatorial chemistry. Applications of heuristic procedures have been presented in the chemical literature, but their use has been discussed only poorly. However, it has become
evident that heuristic methods are not equally applicable to all problems. Indeed, the usefulness of the genetic algorithm can be deduced from the problem to be tackled: the most important prerequisite is that the quality does not playa significant role, i.e. a second best or even worse
solution would be adequate and that the best solution is not necessary to solve the problem. Beyond that, the use of heuristics must be justified by the absence or high degree of complexity of non-heuristic methods.

Published: April 2022

Both in our country and around the world, childless marriages currently remain an important medical and social problem, the frequency of which remains high and has no tendency to decrease. One of the main roles in the structure of this condition is the uterine factor of infertility. In the structure of the uterine factor, a separate place belongs to intrauterine synechiae associated with chronic endometritis. The high prevalence, unclear mechanisms of pathogenesis and the lack of a unified approach to therapy determines not only the relevance of the chosen topic, but also the need for an integrated approach to the management of patients suffering from uterine infertility. The article presents modern ideas about the tactics of treatment of patients with infertility of uterine genesis associated with chronic endometritis and intrauterine synechiae, according to domestic and foreign literature.

Published: April 2022

Purpose. To study the effectiveness of the drug diindolylmethane for the elimination of human papillomavirus (HPV) of high oncogenic risk in women with cervical intraepithelial neoplasia (CIN) of varying severity.
Materials and methods. Conducted a comprehensive examination of 150 women, aged 20 to 49 years, with the presence of CIN. Verification of the diagnosis was carried out on the basis of data from clinical, cytological, colposcopic, and histological studies. HPV typing was carried out using the PCR (Kvant 21 test).
Results. The obtained results emphasize the feasibility of using complex therapy for CIN of varying severity, including etiotropic correction of chronic cervicitis, with the parallel use of the drug diindolylmethane for 6 months, as well as destruction of the cervix in patients with CIN IIIII. The use of the drug diindolylmethane allows, with a statistical degree of certainty, to eliminate HPV of high oncogenic risk in patients with CIN of III.
Conclusion. Despite the fact that we did not receive results indicating that it accelerates the elimination of HPV in patients with CIN III (p0.05), nevertheless, the use of diindolylmethane in patients with CIN III reduces the number of cases (p0.001) requiring expansion of surgical intervention (amputation of the cervix, extirpation of the uterus), which is important for patients of reproductive age.

ZnO nanoparticles
Authors: Horison R. , Sulaiman F.O. , Alfredo D. , Wardana A.A.
Published: April 2022

In this study, a nanocomposite coating method was applied to inhibit the browning
kinetics of apple “Malang”, an Indonesian local commodity that is extensively produced
in the Batu city area. Fresh-cut apple was coated with carrageenan in combination with
ascorbic acid (1% by weight of carrageenan) and zinc oxide (ZnO) nanoparticles (0, 1%
by weight of carrageenan) as filler. The results revealed that all composite materials were
completely blended and confirmed by Fourier-transform infrared (FTIR). Scanning
electron microscopy (SEM) exhibited that ZnO was successfully trapped by the
carrageenan matrix. Notably, no differences in overall liking between uncoated and coated
fruit were observed. The lower browning index (BI) rate in the nanocomposite coated fruit
confirms its effectiveness in maintaining the visual appearance of fresh-cut apples.

Published: April 2022

Dil bilgisi çeviri yönteminden iletişimsel yönteme ve oradan da eylem odaklı yaklaşıma kadar uzanan yabancı dil öğretimi tarihi son yüzyılda önemli ilerlemeler kaydetmiştir. 2001 yılında yayımlanan Diller İçin Avrupa Ortak Çerçeve Metni yabancı dil öğretimine farklı bir bakışı, yeni bir yaklaşımı getirmiştir. Çerçeve metnin yayımlanmasından sonra yapılan araştırmalar ve yürütülen projeler, 2018 ve 2020 yıllarında yeniden genişletilmiş baskı halinde yayımlanan çerçeve metne yeni kavramları, yeni yeterlilikleri ve dolayısıyla yeni tanımlayıcıları eklemiştir. Bu çalışmanın amacı sosyal aktör olarak kabul edilen dil kullanıcısının sözcük dağarcığının, yeni yeterlilikler kapsamında Türkçe sözlüklere girmiş olan sözcüklerle sınırlı kalmamasının önemini vurgulamaktır. Bu çalışma kısaca D-AOBM 2020 olarak adlandırılan, Diller İçin Avrupa Ortak Çerçeve Metni Genişletilmiş Baskıda yer alan tanımlayıcılar bağlamında B1 dil düzeyindeki sosyal aktörün, henüz sözlüklere geçmemiş fakat toplumsal yaşamda sıklıkla kullanılan genelleme sözcük türü ile yabancı dil olarak Türkçe öğretimi sürecinde kullanılan yöntem kitaplarında ne kadar sıklıkla karşılaştığını doküman analizi yöntemi ile taramayı amaçlamaktadır. D-AOBM 2020’de yer alan yeni tanımlayıcıların ve yabancı dil öğretimine getirilen kavramların tümünden, çalışmanın sınırlılıkları kapsamında, bahsedilmemektedir. Fakat Diller İçin Avrupa Ortak Çerçeve Metninin yabancı dil öğretimine kazandırdığı sosyal aktör kavramı çalışma konusunu yakından ilgilendirmektedir. Bu sebeple çalışmanın ilk bölümünde sosyal aktör tanımlanmaya çalışılmıştır. Ardından çalışmada, kısaca D-AOBM 2020 olarak adlandırılacak olan Diller İçin Avrupa Ortak Çerçeve Metni Genişletilmiş Baskı da yer alan Söz Varlığı ve Sözcük Denetimi tanımlayıcıları, doküman analizi yöntemiyle B1 dil düzeylerinde sosyal aktör bağlamında incelenmiştir. Buradan yola çıkılarak genelleme sözcük olarak adlandırılan sözcüklerin, İstanbul Kitabındaki ve Yunus Emre Enstitüsü Yedi İklim Türkçe kitabında kullanım sıklığı tarama yöntemiyle belirlenmiştir. Ardından genelleme sözcük olarak adlandırılan bu sözcüklerin yabancılara Türkçe öğretiminde kullanılmasının önemi ve faydası tartışmaya açılmıştır.

Stunting, according to the WHO, is defined as body length or body height with respect to the same age that is less than minus two standard deviations (<-2SD) from the median standard of the WHO for children growth. Rotenone is a pesticide that can induce an occurrence of disrupted growth on the larvae of zebrafish. Centella asiatica or pegagan is a plant that has antioxidant effects. Zebrafish embryos were treated with pegagan at concentrations of 1.25, 2.5, and 5 µg/ml. Exposure to treatments began from 2 to 72 hpf and development was monitored until the larval age of 9 dpf. Rotenone at a concentration of 12.5 ppb can induce stunting. There was a decrease in the process of bone ossification and an increase in the expression of RANKL in zebrafish larvae induced by rotenone. Meanwhile, the extract of Centella asiatica at concentrations of 2.5 µg/ml and 5 µg/ml was able to increase body length. Pegagan 5 µg/m shown the most significant effect for the increase in bone ossification (p <0.05). Observations of RANKL expression indicated significant reductions in the Centella asiatica extract treatment groups from the lowest concentration 1.25 µg/ml, up to 2.5 µg/ml and 5 µg/ml. Centella asiatica extract of 2.5 µg/ml and 5 µg/ml concentrations can increase the body length of zebrafish larvae, increase bone ossification, and lower the expression of RANKL, which has an effect on the process of osteoclastogenesis.

ИНИЦИИРОВАНИЕ ВЗРЫВА ВЫСОКОВОЛЬТНЫМ РАЗРЯДОМ ПРЕССОВАННЫХ СМЕСЕЙ СЕВИЛЕНА С ПЕРХЛОРАТОМИ НИТРАТОМ АММОНИЯ С ДОБАВКОЙ ПОРОШКООБРАЗНОГО АЛЮМИНИЯ

Применение высоковольтного разряда для инициирования взрыва оправдано, когда требуется строгая синхронизация действий. Типично рабочим процессом, который возбуждается разрядом, является детонация. Чтобы снизить напряжение разряда и повысить стабильность инициирования, используются мощные бризантные взрывчатые вещества (ВВ) с добавкой нанодисперсных металлов, включая алюминий. Однако имеются технические направления (здесь можно назвать применение в элементах динамической защиты танков и в перспективных гиперзвуковых ускорителях типа “blast wave accelerator”), где нанодисперсные металлы не приемлемы из-за невысокой стабильности и дороговизны, а вместо нормальной детонации требуются более мягкие взрывные процессы с тем, чтобы исключить излишнее бризантное воздействие на элементы устройств. В данной работе исследовано инициирование взрыва высоковольтным разрядом в прессованных смесях перхлората и нитрата аммония с севиленом с добавками различных металлов. Севилен - термопластичный клей, сополимер этилена и винилацетата, обладает прекрасной адгезией ко всем компонентам исследуемых смесей и обеспечивает замечательные условия для прессования образцов. Наилучший результат: надежные взрывы в широком диапазоне пористостей образца вплоть до образца с пористостью на уровне 1% при пороговом напряжении от 5,5 до 1,5 кВ получены на смесях перхлората аммония с добавкой 20% порошка алюминия с частицами размером 10 мкм. Замена перхлората аммония на нитрат аммония также демонстрирует хорошие результаты, а при добавлении других металлов (исследовались медь, железо и цинк) взрывы практически отсутствовали вплоть до максимального напряжения 12 кВ, использованного в данной работе. Наиболее вероятная причина: энергичное экзотермическое взаимодействие расплава алюминия, образующегося при электрическом пробое, с перхлоратом аммония. Этот эффект можно попытаться использовать для замены нанодисперсного алюминия на порошок с частицами микронного размера при высоковольтном инициировании детонации мощных вторичных ВВ, если ввести в смесь определенное количество перхлората аммония.

Evaporation of Black Holes in Anti-de Sitter Space-time: A Review
Authors: Gadda Navjot Singh
Published: April 2022

We extensively review the evaporation of black holes in AdS along with their thermal interpretation, holographic description, relative differences between initial and final states of emitted systems and in turn how our geometry is affected while studying these processes along with the current understanding of string theory in these regimes. In addition to the these properties, we are interested in analysing how these ideas relate with semiclassical General Relativity which may arise from different areas of validity for the ads/CFT correspondence. We note on the optimal consequences of compactifications of Supergravity in effective field theories. Using this technique, we further explore the geometrical behavior when gravity is turned on and study how it affects compactifications and allows singularity structures consistent with 2D Geometries. We assume these topologies as naturally interpreted horizon-related phenomenon. Superluminal signalling is ruled out if and only if one assumes that no superradiance occurs during evaporation; but it is allowed within the thin membrane paradigm already introduced earlier in this context.

Perbankan syariah di Indonesia semakin berkembang seiring dengan berkembangnya pertumbuhan penduduk yang berpenduduk mayoritas beragama islam. Perbankan syariah menjadi alternatif sistem perbankan yang memiliki berbagai macam produk dan pelayanan yang beragam akan siklus operasionalnya serta memiliki kemampuan menghasilkan profit menjadi indikator penting untuk keberlanjutan entitas bisnis dan untuk mengukur kemampuan bersaing dalam jangka panjang.Bank syariah adalah bank yang beroperasi dengan tidak mengandalkan bunga. Kedudukan bank syariah dengan para nasabahnya adalah sebagai mitra investor dan pedagang. Pada prinsipnya, Bank Syariah adalah sama dengan perbankan konvensional, yaitu sebagai instrumen intermediasi yang menerima dana dari orang-orang yang surplus dana (dalam bentuk penghimpunan dana) dan menyalurkannya kepada pihak yang membutuhkan (dalam bentuk produk pelemparan dana). Bank syariah menggunakan berbagai teknik dan metode investasi, dimana kontrak hubungan investasi antara bank syariah dengan para nasabahnya disebut dengan istilah pembiayaan. Dalam perbankan, pembiayaan mempunyai peranan penting terutama untuk menyalurkan dana kepada masyarakat untuk menghadapi masalah dan atau modal kerja terutama untuk

Dense Contrastive Visual-Linguistic Pretraining

Published: April 2022

Inspired by the success of BERT, several multimodal representation learning approaches have been proposed that jointly represent image and text. These approaches achieve superior performance by capturing high-level semantic information from large-scale multimodal pretraining. In particular, LXMERT and UNITER adopt visual region feature regression and label classification as pretext tasks. However, they tend to suffer from the problems of noisy labels and sparse semantic annotations, based on the visual features having been pretrained on a crowdsourced dataset with limited and inconsistent semantic labeling.To overcome these issues, we propose unbiased Dense Contrastive Visual-Linguistic Pretraining (DCVLP), which replaces the region regression and classification with cross-modality region contrastive learning that requires no annotations. Two data augmentation strategies (Mask Perturbation and Intra-/Inter-Adversarial Perturbation) are developed to improve the quality of negative samples used in contrastive learning. Overall, DCVLP allows cross-modality dense region contrastive learning in a self-supervised setting independent of any object annotations. We compare our method against prior visual-linguistic pretraining frameworks to validate the superiority of dense contrastive learning on multimodal representation learning.

Fishers are a vital profession to succeed in improving nutrition. However, fate has not been so fortunate as other professions, and still in dera with difficulty is still challenging to get out of the trajectory of poverty. Many factors influence it that there is no significant change in marketing the results of his fishing to consumers directly because they have to go through collecting traders so that the selling price of his fish is far from the market price. This can happen because the marketing of fish catches is still done traditionally, not following the modern marketing that uses digital information technology facilities that have Teresa in Android Mobile. With the support of applications already available on Android Mobile, stay to use it without building its infrastructure. What needs to be encouraged is the support from related agencies, related ministries, Telecommunications companies, and Banking companies.
MANAJEMEN KOPERASI
Authors: Agnusia Nur Adillah
Published: April 2022

Sampai saat ini koperasi belum mampu menunjukkan kontribusi yang signifikan terhadap perekonomian nasional. Teridentifikasi 7 masalah kualitatif yang dialami koperasi Indonesia, yaitu (1) citra, (2) kemandirian, (3) kualitas SDM, (4) Manajemen, (5) ketersediaan dan (6) akses permodalan, (7) jaringan usaha (Suryadharma Ali, 2004). Koperasi memiliki citra sebagai organisasi ketingalan zaman karena kualitas SDM yang kurang dan kemampuan manajerial yang tidak kompeten sehingga kebanyakan orang memandang sebelah mata terhadap koperasi, padahal koperasi didirikan sebagai soko guru ekonomi nasional. Pengelolaan dan pembinaan SDM yang tepat diperlukan jika koperasi ingin bertahan dalam bisnis dan menambah daya kompetitifnya. Tapi sejauh ini jarang sekali dilakukan pemetaan kondisi MSDM sebuah koperasi. Padahal dalam aspek SDM inilah koperasi paling banyak disorot sebagai salah satu sumber permasalahan lemahnya keberadaan koperasi. Oleh karena itu perlu adanya identifikasi masalah MSDM

Extended Object Tracking Using Sets Of Trajectories with a PHD Filter
Authors: Sjudin Jakob , Marcusson Martin , Svensson Lennart , Hammarstrand Lars
Published: April 2022

PHD filtering is a common and effective multiple object tracking (MOT) algorithm used in scenarios where the number of objects and their states are unknown. In scenarios where each object can generate multiple measurements per scan, some PHD filters can estimate the extent of the objects as well as their kinematic properties. Most of these approaches are, however, not able to inherently estimate trajectories and rely on ad-hoc methods, such as different labeling schemes, to build trajectories from the state estimates. This paper presents a Gamma Gaussian inverse Wishart mixture PHD filter that can directly estimate sets of trajectories of extended targets by expanding previous research on tracking sets of trajectories for point source objects to handle extended objects. The new filter is compared to an existing extended PHD filter that uses a labeling scheme to build trajectories, and it is shown that the new filter can estimate object trajectories more reliably.
IMPROVING LAKU PANDAI SERVICES TO REDUCE POVERTY

Published: April 2022

The intelligent behavior services currently provided by the Bank are only limited to account opening services, accepting deposits, payments, and purchasing vouchers for Telkomsel, Indosat, PLN, PDAM, and others. This intelligent behavior service has attracted much interest, especially for people who have not been in direct contact with the banking world. In addition to the time of service that knows no time, providing services for agents is not complicated. Hence, the current business model is very suitable to meet the needs of the people—The daily requirements of those the banking sector has not exploited.However, the purpose of this service is not only to fulfill daily needs but also to increase income by helping capital for people in need; thus, if the capacity increases, it will directly affect payment, which in the end, the community will be more and prosperous. However, banks have not carried out the service for distributing credit; in addition to the absence of regulations, the form of the credit distribution scheme is unclear.

Warum klingt der Tritonus teuflisch?
Authors: Willimek Bernd , Willimek Daniela
Published: April 2022

Der Klang des Tritonus hat im Allgemeinen eine unangenehme negative Wirkung auf den Hörer. So wurde er schon als scheußlich, hässlich, heimtückisch und teuflisch beschrieben. Bis jetzt gab es noch keine allgemein anerkannte Erklärung für diese Wirkung. In dieser Arbeit wird eine Begründung vorgestellt, die auf der Strebetendenz-Theorie basiert. Die musiktheoretische Besonderheit dieses Klangs liegt darin, dass seine beiden Leittöne nicht eindeutig identifiziert werden können. Man weiß nicht, welcher seiner beiden Töne nach oben und welcher nach unten weist. In einem Experiment lässt sich nachweisen, dass der Tritonus all seine negativen Klangcharaktere verliert, wenn man zum Tritonus noch einen weiteren Klang kurz anschlägt, der den Leittönen eine eindeutige Orientierung verleiht. Hört man dann wieder auf den Tritonus, klingt dieser auf einmal harmlos. Hierdurch erweist sich die Ambivalenz seiner Leittöne als Ursache für die unangenehme Wirkung des Tritonus.
