Authors: Abdelbaki Cherifa , Boukli Hacène Fouad
Published: December 2023

L’altération de l’environnement naturel, notamment le milieu aquifère est devenue progressivement une préoccupation mondiale. En Algérie, la principale source de satisfaction de la demande en eau est l’eau souterraine, du fait de son exploitation relativement facile. La croissance démographique et la modernisation de l’agriculture entraînent un grand problème de détérioration de la qualité de cette source souterraine, déjà en quantité limitée. Actuellement, les cours d’eau de région étudiée reçoivent en permanence les rejets urbains et industriels chargés d’éléments chimiques et organiques, souvent toxiques. Ces substances polluantes peuvent affecter de façon dangereuse la santé publique, si elle continue à être déversées dans la nature sans traitement préalable. Le mécanisme de pollution des eaux souterraines est un processus évolutif dans l’espace et dans le temps, difficilement maîtrisable. Les systèmes d’information géographique permettent d’effectuer une analyse spatiale dans le but d'avoir des cartes de synthèse et de voir clairement la dégradation de la qualité des eaux souterraines du Groupement Urbain de Tlemcen.

Authors: Belkhiri Zina , Zeroual Mostefa , Ben Moussa Hocine , Zitouni Bariza
Published: December 2023

A fuel cell is a promising energy conversion system that will eventually become the first-choice for producing power because of its clean or zero-emission nature. A steady-state, two-dimensional mathematical model with a complete set of governing equations valid in different components of a PEM fuel cell was developed to illustrate the temperature and water content effects on proton exchange membrane (PEM) fuel cell performance. This model considers the transport of species and water along the porous media: gas diffusion layers (GDL) anode and cathode, and the membrane of PEMFC fuel cell. To improve the kinetics of electrochemical reactions at the electrodes and thus reduce the activation overvoltage: increase the gas diffusion electrodes reduce the drop ohmic, especially in the proton conductive membrane through an increase in ionic conductivity. The electrochemical performance of a fuel cell will be strongly depend temperature and water content.

Authors: Nemsi Salima , Barazane Linda , Diaf Said , Malek Ali
Published: December 2023

Solar panels have a nonlinear voltage-current characteristic, with a distinct maximum power point (MPP), which depends on the environmental factors, such as temperature and irradiation. In order to continuously harvest maximum power from the solar panels, they have to operate at their MPP despite the inevitable changes in the environment. This is why the controllers of all solar power electronic converters employ some method for maximum power point tracking (MPPT). This paper presents a comparative study between two most popular algorithms techniques which are incremental conductance (INC) and perturb and observe (P&O) in order to optimize the efficiency of the solar generator. The MPPT techniques will be compared, by using Matlab tool Simulink.

Exploring the Role of Bispectral Index in Interrupting CPR for ROSC Diagnosis: A Call for Further Research
Authors: ÖZDEMİR Serdar
Published: December 2023

The current approach in cardiopulmonary resuscitation (CPR) involves interrupting the chest compressions to assess the pulse and diagnose Return of Spontaneous Circulation (ROSC). This critical step is essential for determining the effectiveness of resuscitation efforts. However, the interruption of CPR poses a challenge, prompting researchers to explore alternative methods for diagnosing ROSC without compromising the ongoing resuscitation process.

One potential solution proposed in the literature is the use of the Bispectral Index (BIS). BIS is a numerical value derived from processed electroencephalogram data, providing a measure of the depth of anesthesia or sedation. Some studies have reported an increase in BIS values following successful ROSC during CPR. This observation suggests that monitoring BIS levels could offer real-time information about cerebral perfusion and neurological status, eliminating the need for pulse checks that require CPR interruption.

Despite these promising indications, it is crucial to acknowledge the limited existing literature on the subject. The evidence supporting the use of BIS in diagnosing ROSC during CPR is not yet robust, and further research is warranted. Researchers are encouraged to delve into this unexplored area, conducting comprehensive studies to assess the reliability and effectiveness of BIS as a tool for continuous monitoring during resuscitation efforts.

In conclusion, while the concept of using BIS to diagnose ROSC during CPR holds potential, it remains an area that requires substantial research attention. The limited existing literature underscores the need for more extensive investigations to determine the feasibility and reliability of integrating BIS into the CPR protocol. As technology advances, exploring innovative approaches for continuous assessment during resuscitation becomes imperative for improving outcomes in cardiac arrest scenarios
Preoperative risk factors of airway complications in adult lung transplant recipients: A systematic review and meta-analysis
Authors: Subasi Mahmut , Duger Mustafa
Published: December 2023

Background: In this systematic review and meta-analysis, we aimed to identify recipient-related preoperative risk factors for airway complications following lung transplantation in adults.

Methods: Articles published between November 1995 and February 2023 were searched by a thorough exploration of databases. Studies that addressed recipient-related risk factors for airway complications following adult lung transplantation, such as cohorts, case-control, or cross-sectional studies, were included. Fixed-effects or random-effects models were used to calculate the odds ratios (ORs) or mean differences (MDs) with 95% confidence interval (CI).

Results: Twenty-one studies including a total of 38,321 recipients fulfilled the inclusion criteria. Based on the pooled analyses, taller height (MD=5.98, 95% CI: 5.69-6.27, I2=57.32%), intraoperative mechanical ventilation (OR=1.83, 95% CI: 1.41-2.38, I2=0%), male sex (OR=1.52, 95% CI: 1.33-1.74, I2 =15.91%), preoperative extracorporeal membrane oxygenation (OR=1.58, 95% CI: 1.1-2.26, I2=41.47%), and preoperative steroid use (OR=1.21, 95% CI: 1.04-1.41, I2=0%) elevated the risk of airway complications following lung transplantation.

Conclusion: Taller height, intraoperative mechanical ventilation, male sex, preoperative extracorporeal membrane oxygenation, and preoperative steroid use can increase the risk of airway complications after lung transplantation. Identifying high-risk recipients or riskless situations can support the advancement of selective treatments or prevent the unnecessary avoidance of certain interventions.

Authors: Compa Tadeusz
Published: December 2023

Rozwój komunikacji lotniczej niesie ze sobą wiele zagrożeń, których źródłem mogą być siły przyrody lub zawodność sprzętu. Największym zagrożeniem jest jednak czynnik ludzki, a zwłaszcza świadoma destrukcyjna działalność człowieka. Zagrożenia ze strony sił przyrody da się przewidzieć i poprzez odpowiednie zarządzanie ryzykiem można uniknąć wielu tragicznych zdarzeń. W opinii specjalistów od bezpieczeństwa lotniczego, oraz samych pasażerów, za największe zagrożenie uznaje się terroryzm lotniczy, bezprawne przejęcie kontroli nad statkiem powietrznym oraz błąd ludzki. Biorąc pod uwagę różnorodność zagrożeń, jakie mogą mieć miejsce w lotnictwie, autor skupił się na terroryzmie powietrznym, a zwłaszcza formach i metodach przeprowadzenia ataku terrorystycznego. Pominięto problemy przeciwdziałania innym rodzajom zagrożeń ze względu na zbyt szeroki zakres tematyczny.

Exact computation of the asymptotic variance matrix for a tuple of multinomial distributions with dependent parameters
Authors: Geraldo Issa Cherif
Published: December 2023

In this paper, we consider a statistical model consisting of an s-tuple of multinomial distributions whose parameters are dependent. This model is used in road safety to study the effect of a measure implemented on a set of s sites comprising a total of r accident severity levels and is depending on a parameter vector of 1+sr components under s equality constraints. The computation of the so important asymptotic variance matrix W requires some numerical matrix inversions which become very complicated for large values of s and r. To circumvent this difficulty, we use Schur complement for the exact analytic inversion and we propose a strategy for calculating W. We illustrate the effectiveness of our approach using simulated data.

Giriş: Sepsis, yoğun bakım ünitesindeki (YBÜ) ölümlerin en önemli nedenlerinden biridir. Tedavi başlangıcında antibiyotikler ampirik olarak seçilir, daha sonra kültür sonuçlarına ve tedavi cevabına göre tedavi değiştirilir. Kritik hastalarda kültür pozitifliği ile ilişkili faktörler önemli bir konudur. Bu nedenle, çalışmamızda kan kültürü pozitifliği ile ilişkili faktörler, özellikle de kan kültürü örneklemesi sırasındaki kan glukoz seviyesi ile kan kültürü arasındaki ilişkinin incelenmesi amaçlanmıştır.

Gereç ve Yöntemler: Bu prospektif gözlemsel çalışma 1 Ekim 2017 ile 1 Ocak 2018 tarihleri arasında Sağlık Bilimleri Üniversitesi, Dr. Suat Seren Göğüs Hastalıkları ve Cerrahisi Eğitim ve Araştırma Hastanesi Yoğun Bakım Ünitesinde gerçekleştirilmiştir. Kan kültürü hastaların iki ayrı bölgesinden steril koşullar altında alınmıştır. Yatak başı kan şekeri ölçüm cihazı ile eş zamanlı kan glukoz düzeyi ölçülmüştür ve iki ölçümün ortalaması alınmıştır. Kan kültürü pozitifliği etkileyen faktörlerin belirlenmesi için multivariate regresyon analizi kullanılmıştır.

Bulgular: Çalışmaya 174 hasta alındı ve 53 (%30) hastada kan kültürü pozitifliği saptanmıştır. Univariate analizde kan glukoz düzeyi, santral venöz kateter varlığı, antibiyotik tedavisi, vazoaktif ilaç kullanımı ve diabetes mellitus (DM) kültür pozitifliği ile ilişki bulunmuştur. Multivariate regresyon analizinde sadece DM, kültür pozitifliği ile ilişkili bulunmuştur (OR 5.63 [95% CI 1.99-15.91] p=0,001).

Sonuç: DM kan kültürü pozitifliği olasılığını arttırabilir. Bu durum kontrolsüz DM’den kaynaklanmış olabilir. Bu riskin kontrolsüz hastalardan kaynaklanıp kaynaklanmadığını değerlendirmek için iyi tasarlanmış daha ileri çalışmalara ihtiyaç vardır.

Published: December 2023

Latvian Darkhead (LD) is a local sheep breed and a genetic resource in Latvia. Preservation and development of the sheep population in the local region is important for the recultivation of fields, it serves as a source for export and local use, as well as waste wool can be applied for developing new products, for example, sorbents for volatile organic pollutants. Therefore, investigation of the sorption properties of the LD sheep wool fibers is under interest. In addition, modification options of the wool for improvement of properties are viewed. Therefore, in the present work, sheep wool fibers as well as accelerated electron-irradiated fibers are analyzed and compared. Fourier transform infrared (FTIR) spectrometry is applied to develop the sorption testing system of volatile organic compounds. An analytical system consisting of a volatile organic compound source, sheep wool filter, and FTIR spectrometry cell is tested and applied for analysis of wool sorption properties for acetone molecules. Registration of the FTIR spectra was performed within the range of 600-4000 cm-1, in the nitrogen flow of about 150mL/min. FTIR analysis shows, that the accelerated electron irradiated sheep wool fibers absorb acetone of about 33% more than non-irradiated fibers. The obtained results will be used for developing recommendations for filter producers to fabricate filter components containing LD sheep wool fibers.

Published: December 2023

Over the years, the issue of tax policy design has been a major concern requiring extensive scientific research. In light of these considerations, the purpose of this paper is to investigate the extent to which prior research has focused on tax incentives in Indonesia.  This paper employs bibliometric analytic techniques to examine the empirical literature published between 1987 and 2023. This paper utilizes the Scopus database and the "bibliometrix" package to conduct a bibliometric analysis. The analysis emphasizes on the most important information regarding the analysis of scientific production by field (journals, authors, and keywords), mapping the research path and proposing initiatives based on prior literature. This investigation revealed various results. Initially, the government must offer 'renewable' and 'sustainable' tax incentives to vital businesses and economic sectors. Second, tax incentives should also be provided to the MSMEs industry, as this industry has the largest market as a pillar of Indonesia's economy. There is a great deal of room for theoretical development, contextualization, and methodological contributions. In addition, this study provides policy recommendations from prior research and directions for future research.

Published: December 2023

PT Rekadaya Multi Adiprima is a manufacturing industry that produces automotive components, especially for four-wheeled vehicles. PT Rekadaya Multi Adiprima is divided into four production divisions, namely the metal division, non-woven division, plastic division (service hole), and interior division. During the implementation of production at PT Rekadaya Multi Adiprima, there was still a customer claims process which was very detrimental to PT Rekadaya Multi Adiprima. Based on the results of interviews with quality staff, it was found that the number of claims occurring in 2022 at plant 1 of PT Rekadaya Multi Adiprima exceeded the tolerance set by the company, namely 0.05%. Based on these problems, further observations need to be made to resolve existing problems. The method used to solve this problem is the DMAIC (Define, Measure, Analyze, Improve, control) method with the help of the FMEA (Failure Mode and Effects Analysis) method based on customer claim data from July 2022- December 2022. The defining stage is carried out by analysis to determine product with the highest level of claims, the measurement stage involves calculating the DPMO value and Sigma Level, the analysis stage aims to find out the cause of the claim using the help of a fishbone diagram and the FMEA Table, in the improv stage the aim is to find and make improvements with the help of the 5W+1H Table based on the diagram fishbone and FMEA tables that have been made previously. As well as carrying out design using the NIDA method, the final stage of control is monitoring the expected improvement results. The results before the improvement, the DPMO value was 77,000 units with a sigma level of 2.925 and after the improvement the DPMO value decreased to 17,400 units with a sigma level of 3.611. The results of the improvements made reduced the level of customer claims by 61.93%.

Published: December 2023

This study examines the extent to which political, legal, and social environmental factors influence procurement performance in local government. To meet the study objective the quantitative approach and cross-sectional survey design were used in data collection and analysis. The study used both descriptive and inferential analysis. The data were collected from 92 procurement practitioners of the local government authorities. The findings revealed that the legal environment and political environment attributes significantly affect procurement performance in local government. Conversely, social attributes in procurement functions do not predict the procurement performance of local government. This study has extended the application of systems theory in public procurement to the Tanzania context. The policymakers and practitioners of local government are required to be aware of the various external environmental factors and how each factor influences its performance.

This paper revisits trilateration in three-dimensional positioning. Specifically, range between a positioning target and the reference points through time-of-flight (ToF) measurements.  In a ToF, range is yielded by multiplying the time required by a wave to travel between two points and its propagation speed. Position of the target can be then estimated once the number of references are adequate, i.e. at least three for two-dimensional positioning and four for three-dimensional one. In this paper, the positioning is considered for navigation where the target moves following a trajectory whilst the ToFs take place in a certain period. The target position at the time is computed based on the ToFs through least square estimation. Through a numerical simulation, it is shown that the trilateration can track a target’s trajectory despite the decreasing performance at the end of the course.

In today's society, cultivating students' "global competence", that is, cultivating innovative talents with more international competitiveness and cross-cultural leadership, has become an important goal of national talent training. The present research focus on the cultivation of global competence of international talents, while there is few research on the influencing factors of global competence. The paper explores the impact of number of foreign teachers, English compulsory course credits, English elective course credits, and professional bilingual course credits on the cultivation of students’ global competence in China’s local universities. It is important to find the influencing factors to help select appropriate training modes, so as to improve college students’ global competence.

Campos de Altitude são uma fitofisionomia do Domínio Atlântico, que pouco se sabe sobre as características ecológicas, devido à subamostragem ou desvalorização. Apresenta-se uma lista de espécies classificadas em diferentes estágios de conservação, para fins de produção de novos dados sobre as áreas em questão, corroborando com políticas públicas que visam à conservação desse ecossistema. As áreas estudadas englobam o Planalto de Poços de Caldas e Serra de Caldas, que abrange os municípios de Poços de Caldas, Caldas, Andradas (Estado de Minas Gerais), e Águas da Prata (Estado de São Paulo). Utilizaram-se dados de coletas registradas na área de estudo com ocorrência nesta fitofisionomia. A lista gerada foi comparada com a Resolução CONAMA n° 423/2010. Os resultados indicaram 187 espécies entre: Vegetação Primária (Estágios Médio e Avançado de Regeneração); Estágio Inicial; e espécies Endêmicas ou Raras. A representatividade encontrada denota biodiversidade florística, e a variação dos hábitos vegetacionais demonstram a grande importância abiótica desse ecossistema.

L’article présente le corpus journalistique comme une ressource incontournable dans
l’acquisition d’un savoir critique, compétence qui doit s’enchâsser dans l’apprentissage de
la traduction économique et financière, à l’heure où on anticipe qu’une proportion
croissante de textes issus de ces domaines se prêteront à la traduction automatique
neuronale. L’article vise à soutenir une pratique enseignante qui conçoit le travail des
traductaires comme étant activement engagé dans la construction des réalités sociales. Cette
posture est exposée sous les auspices de l’analyse critique du discours, dont la pertinence
s’inscrit dans le contexte élargi de la financiarisation de l’économie. Après une brève
synthèse des approches en enseignement de la traduction spécialisée dans les domaines de
l’économie et de la finance, l’article propose des clefs d’analyse critique du corpus
journalistique, réparties en trois catégories : lexique et vocabulaire, agentivité et voix.
Quelques aspects praxéologiques sont abordés, notamment la manière de construire un corpus
de textes journalistiques.

Microsporidia are eukaryotic, obligate intracellular parasites that infect a wide range of hosts, leading to health and economic burdens worldwide. Microsporidia use an unusual invasion organelle called the polar tube (PT), which is ejected from a dormant spore at ultra-fast speeds, to infect host cells. The mechanics of PT ejection are impressive.

) and into the host cell. Considering the large hydraulic resistance in an extremely thin tube and the low-Reynolds-number nature of the process, it is not known how microsporidia can achieve this ultrafast event. In this study, we use Serial Block-Face Scanning Electron Microscopy to capture 3-dimensional snapshots of
A. algerae
spores in different states of the PT ejection process. Grounded in these data, we propose a theoretical framework starting with a systematic exploration of possible topological connectivity amongst organelles, and assess the energy requirements of the resulting models. We perform PT ring experiments in media of varying viscosity, and use the results to rank our proposed hypotheses based on their predicted energy requirement. We also present a possible mechanism for cargo translocation, and quantitatively compare our predictions to experimental observations. Our study provides a comprehensive biophysical analysis of the energy dissipation of microsporidian infection process and demonstrates the extreme limits of cellular hydraulics.Microsporidia are a group of spore-forming, intracellular parasites that infect a wide range of hosts (including humans). Once triggered, microsporidian spores (3-4

Although this process has fascinated biologists for a century, the biophysical mechanisms underlying PT extrusion are not understood. We thus take a data-driven approach to generate models for the physical basis of PT ring and cargo transport through the PT. Our approach here demonstrates the extreme limits of cellular hydraulics and the potential applications of biophysical approaches to other cellular architectures.

Alcohol consumption in pregnancy can affect genome regulation in the developing offspring but results have been contradictory. We employed a physiologically relevant murine model of short-term moderate prenatal alcohol exposure (PAE) resembling common patterns of alcohol consumption in pregnancy. Moderate early PAE was sufficient to affect site-specific DNA methylation in new-born pups without altering behavioural outcomes in adult littermates. Whole genome-bisulphite sequencing of neonatal brain and liver revealed stochastic influence on DNA methylation that was mostly tissue-specific, with some perturbations likely originating as early as gastrulation. Methylation changes were enriched in non-coding genomic regions with regulatory potential indicative of broad effects of alcohol on genome regulation. Replication studies in human cohorts with fetal alcohol spectrum disorder suggested some effects were metastable at genes linked to disease-relevant traits including facial morphology, intelligence, educational attainment, autism, and schizophrenia. A maternal diet high in folate and choline protected against some of the damaging effects of PAE on DNA methylation. Our studies demonstrate that moderate early exposure is sufficient to affect fetal genome regulation even in the absence of overt phenotypic changes and highlight a role for preventative maternal dietary interventions.
Microprism-based two-photon imaging of the mouse inferior colliculus reveals novel organizational principles of the auditory midbrain

To navigate real-world listening conditions, the auditory system relies on the integration of multiple sources of information. However, to avoid inappropriate cross-talk between inputs, highly connected neural systems need to strike a balance between integration and segregation. Here, we develop a novel approach to examine how repeated neurochemical modules in the mouse inferior colliculus lateral cortex (LC) allow controlled integration of its multimodal inputs. The LC had been impossible to study via imaging because it is buried in a sulcus. Therefore we coupled two-photon microscopy with the use of a microprism to reveal the first-ever sagittal views of the LC to examine neuronal responses with respect to its neurochemical motifs under anesthetized and awake conditions. This approach revealed marked differences in the acoustic response properties of LC and neighboring nonlemniscal portions of the inferior colliculus. In addition, we observed that the module and matrix cellular motifs of the LC displayed distinct somatosensory and auditory responses. Specifically, neurons in modules demonstrated primarily offset responses to acoustic stimuli with enhancement in responses to bimodal stimuli, whereas matrix neurons showed onset response to acoustic stimuli and suppressed responses to bimodal stimulation. Thus, this new approach revealed that the repeated structural motifs of the LC permit functional integration of multimodal inputs while retaining distinct response properties.
