Published: September 2023

This concise presents a power efficient level shifter using regulated cross-coupled network with split inverter. With the use of regulated cross-coupled network, power dissipation of the pull-up region drastically decreases. Level shifters convert the voltage levels which are below the threshold voltage to the acceptable voltage levels by decreasing the transistor size. A Split inverter is used at the output to decrease the short circuit current. Modified Split inverter along with the load capacitor at the output is used to increase the speed and to decrease the power consumption. This LS can save 31% power compared to other techniques. The proposed level shifter works effectively at high speed and consumes less power. For simulation, LT spice tool of 50 nm technology and 90 nm technology is used.

Authors: Fimahali Ahmad Yusuf , Sumiati Sumiati
Published: September 2023

PT XYZ is a company engaged in Bottled Drinking Water (AMDK) with the brand "Santri" and has been operating since 1997. The raw materials used come from the Umbulan spring located in Mulyorejo hamlet, Pasuruan regency, East Java which is famous for its clarity. The results of the interview with the company, PT XYZ currently has not implemented quality control methods. Currently the quality of AMDK products PT XYZ has not been maximized, this is shown by the number of defective products that are greater than the established standards. Products with a packaging size of 240 ml are products with the highest percentage of defects. To overcome this problem, the Define, Measure, Analyze, Improve, and Control (DMAIC) approach is used in Six Sigma which is able to reduce defects and also with the FMEA method. Calculation with the Six Sigma method, there has been an increase in Sigma Level after improvement. Meanwhile, analysis using the FMEA method found that the RPN value decreased after the recommendations were implemented. This can be seen from the RPN value at the control stage is smaller than the RPN at the Analyze stage, thus showing the success of the corrective actions that have been taken.

This study aims to present appropriate selection methods for evaluation, analysis, and comparison between different ballast water treatment technology systems in order to make good decisions in selecting the most optimal treatment system. This research designed a ballast water filter device on the John Lie training ship to prevent marine pollution due to species movement through the ballast water transfer process by referring to the D2 standard of the IMO Ballast Water Management Convention. During the ballasting process, ballast water contains thousands of species of marine animals and plants that are carried in ballast tanks, causing problems for the marine environment and human health.  The modification of the filtration tool designed by the researcher used a 0,1 mm and 0,01 mm net tied to the ballast tank inlet pipe using a clamp on the ballast pipe of the John Lie training ship. This can fully be used during the process of filling ballast water from port seawater to enter the ballast tank through this filtration system. The results shown after passing the filter with a total plate count of 36 microorganisms indicate that the filtration system designed by the researcher can meet the D2 standard of the IMO BWM Convention Regulation.

COMPENSATORY-ADAPTIVE REACTIONS IN RADIATION PATHOLOGY
Authors: Шашлов С.В. , Пузырева Г.А.
Published: September 2023

Экспериментально, используя гистологические и гистохимические методики установлено, что в организме облученных животных в течение первых 15-30 минут у крыс и у обезьян при церебральной форме острой лучевой болезни со стороны клеток АPUD-системы и эндокринной системы почек наблюдается повышение их функциональной активности. Это можно расценивать как адаптивную реакцию на воздействие, носящую компенсаторно-приспособительный характер и запускающую сложные нейрогуморальные реакции, лежащие в основе многих патологических состояний. Проведен анализ подобных реакций при других формах лучевой патологии. В клетках АPUD-системы надпочечников и двенадцатиперстной кишки крыс был выявлен сходный фазный характер морфофункциональных изменений, не зависящий от их локализации: фаза усиления секреторной и синтезирующей функций (5-30 минут); фаза неустойчивого состояния, выражающаяся либо в усилении, либо ослабления той или другой функции (30 минут - 6 часов); фаза снижения и последующего угнетения функциональной деятельности клеток (6-24 часов). Подобные реакции прослеживались и у лиц, погибших после аварии на Чернобыльской АЭС. При любых формах лучевой патологии в организме облученных животных и человека развиваются адаптивные реакции, носящие компенсаторно-приспособительный характер. Их своевременное выявление открывает новые возможности для разработки эффективных и безопасных средств терапии и профилактики лучевой болезни

Experimentally, using histological and histochemical techniques, it was found that in the body of irradiated animals during the first 15-30 minutes in rats and monkeys with the cerebral form of acute radiation sickness from the cells of the APUD system and the endocrine system of the kidneys, an increase in their functional activity is observed. This can be regarded as an adaptive reaction to exposure, having a compensatory-adaptive character and triggering complex neurohumoral reactions underlying many pathological conditions. The analysis of similar reactions in other forms of radiation pathology was carried out. In the cells of the adrenal and duodenal APUD system of rats, a similar phase character of morphofunctional changes was revealed, independent of their localization: the phase of strengthening secretory and synthesizing functions (5-30 minutes); the phase of unstable state, expressed either in strengthening or weakening of one or another function (30 minutes-6 hours); the phase of decrease and subsequent inhibition of the functional activity of cells (6-24 hours). Similar reactions were observed in people who died after the Chernobyl accident. In all forms of radiation pathology, adaptive reactions of a compensatory and adaptive nature develop in the body of irradiated animals and humans. Their timely detection opens up new opportunities for the development of effective and safe means of therapy and prevention of radiation sickness

Published: September 2023

Широкое распространение аллергической патологии и неуклонный рост уровня заболеваемости, увеличение финансовых затрат на обследование и лечение, отсутствие подлинного учета и, в результате, разница в уровне заболеваемости между статистическими формами и реальной частотой аллергических заболеваний делают эту проблему чрезвычайно актуальной для исследования. В данной статье были проанализированы материалы, которые были получены при помощи анонимного анкетирования для населения Рамонского и Нижнедевицкого районов Воронежской области. Указанные районы были выбраны на основании оценки средних многолетних показателей заболеваемости поллинозом по данным статистических учетно-отчетных материалов, анализа показателя лесистости, а также факта наличия амброзии на исследуемых территориях с проведением корреляционного анализа связи имеющихся факторов. Благодаря установленной корреляционной зависимости исследуемые районы были разделены на условно благополучную и неблагополучную территории по развитию поллиноза. Анкетирование, проведенное среди 413 респондентов, подтвердило гипотезу о достоверно более высоких шансах заболевания поллинозом на территории неблагополучного района, а также выявило недостаточный учет заболеваемости в медицинских учреждениях, в результате оценки установления диагноза в медицинской организации по данным анкетного опроса населения

The wide spread of allergic pathology and the steady increase in the incidence rate, the increase in financial costs for examination and treatment, the lack of true accounting and, as a result, the difference in the incidence rate between statistical forms and the actual frequency of allergic diseases make this problem extremely relevant for research. This article analyzed the materials that were obtained using an anonymous survey for the population of the Ramonsky and Nizhnedevitsky districts of the Voronezh region. These areas were selected on the basis of an assessment of the average long-term incidence of hay fever according to statistical accounting and reporting materials, an analysis of the forest cover index, as well as the fact of the presence of ragweed in the study areas with a correlation analysis of the relationship between existing factors. Due to the established correlation dependence, the studied areas were divided into conditionally safe and unfavorable territories according to the development of hay fever. A survey conducted among 413 respondents confirmed the hypothesis of significantly higher chances of hay fever in a disadvantaged area, and also revealed insufficient accounting for the incidence in medical institutions, as a result of assessing the diagnosis in a medical organization according to a questionnaire survey of the population

The dataset includes electricity production data from 7 turbines in the MWPP during 2019, along with ocean measurements such as significant wave height, wave period, wave energy flux, swell direction, and wind direction. All models in the paper have varying coefficients which change with the significant wave height. The methodology includes the use of generalized least squares and local polynomial kernel methodologies for coefficient estimation.
A time domain approach for the optimal control of wave energy converter arrays
Authors: Shabara Mohamed , Abdelkhalik Ossama
Published: September 2023

Wave energy converters typically use various control methods to extract energy from ocean waves. The objective of the control system is to optimize the energy extraction process, taking into account the dynamics of the system and the wave conditions. The task of deriving the optimal control laws of wave energy converter arrays for regular and irregular waves using the Pontryagin minimum principle was previously investigated in the literature. The result is a combination between the singular arc and bang-bang control laws. For irregular waves, some complexity arises due to the radiation state-space representation, which requires ignoring the hydrodynamic coupling terms related to the added mass and radiation-damping coefficients; this reduces the computational complexity of the control force but adversely affects the solution's accuracy. Also, the derived control laws are specific to a particular wave condition. Recently, the optimal control of a flexible buoy wave energy converter was derived using the convolution representation for the radiation force. In this work, the optimal control laws of flexible buoy wave energy converters are modified to simulate wave energy converter arrays; then, the results are compared to those obtained by dropping the hydrodynamic radiation coupling terms. Although using a convolution representation adds computational complexity to the optimal control problem, it generates an equation that is generic to any wave condition, can be used with any wave spectrum, and provides an expression for the switching condition.
The contaminated library: Microbes in book culture
Authors: Overmann Jörg , Schneider Ulrich Johannes , Mackert Christoph
Published: September 2023

The contaminated book as a cultural asset is presented from three perspectives: philosophy, microbiology and cultural studies including medieval studies. The prejudice of the microbe as the enemy of the collection is questioned. Instead, the microbe is brought to the fore and made contextually visible as a book-biographical sign: traces on the book, including microbial ones, can bear witness to fire, flood, evacuation, and historical epidemics. For this witnessing, different readings of 'world' and of 'dead/living' must be considered, working toward a theory of things. It is based on studies of objects in medieval anthologies in the holdings of the Leipzig University Library, which have also been studied using microbiological and molecular biological methods at the DSMZ-German Collection of Microorganisms and Cell Cultures in Braunschweig. For the determination of the book biographies, both collections form mutual references. A new readability of the 'world as a book' is shown, which is made readable through its DNA, but also through its cultivation needs. With the idea of the book as habitat, a new view of the relationship between cultural property and microbe is opened - against destructive contamination towards the microbe as innovation potential for collections.

Atypical pneumonia accounts for 15 to 30% of the community-acquired pneumonias, and 7 to 14% of those admitted in ICU. Several bacteria may be involved, while Legionella pneumophila, Mycoplasma pneumoniae et Chlamydophila pneumoniae are the most frequently observed. Legionnaires’ disease is the most frequent one in ICU. It has also the poorest prognostic with ICU mortality up to 40% and is usually observed in comorbid or immunocompromised patients. On the other hand, most Chlamydophila pneumoniae and Mycoplasma pneumoniae pneumonias are documented in children or young adults without comorbidity, and their prognostic is usually better, but ICU mortality is still close to 25%. Macrolides and fluoroquinolones are currently the antibiotics of choice. Some specific features in the ICU care of these pneumonias must be known, also with low clinical evidence. Less common bacteria may be documented in the ICU such as Chlamydia psittacosis, Coxiella burnetii or Burkholderia pseudomallei, whose mortality may be up to 50%.
Leptospirose en réanimation

Published: September 2023

La leptospirose est une pathologie ubiquitaire, avec des incidences plus élevées dans les zones tropicales et sub-tropicales. La survenue de défaillances chez des hommes jeunes en bonne santé peut conduire le patient en réanimation, en particulier : une insuffisance rénale aiguë avec hypokaliémie, un ictère à bilirubine conjuguée, un tableau pulmonaire avec hémorragie intra-alvéolaire, une thrombopénie profonde et/ou un état de choc. En zone tempérée, le challenge reste d’évoquer le diagnostic, tandis qu’en zone d’endémie (comme les Départements d’Outre-Mer français), il faut savoir éliminer tous les diagnostics différentiels. Le diagnostic biologique repose sur la réalisation d’une PCR spécifique sanguine ou urinaire. La prise en charge consiste en une antibiothérapie par amoxicilline ou céphalosporines de troisième génération et en un traitement symptomatique des défaillances d’organe. Le pronostic est bon et doit faire discuter des thérapeutiques d’exception (Oxygénation par membrane extra-corporelle, Desmopressine) en cas de défaillance d’organes réfractaire.
