Published: July 2023

يعد الجفاف ظاهرة طبيعية ينعكس تأثيرها بشكل مباشر على الانشطة البشرية بشكل عام والانشطة الاقتصادية (الزراعية، الصناعية) التي يرتبط نجاحها بالموارد المائية (السطحية، الجوفية) ارتباطا وثيقاً، وهذا يعني ان اي تناقص في معدلات الوارد المائي سيهدد تلك الانشطة بشكل كبير، لهذا باتت ظاهرة الجفاف من أكثر المخاطر الطبيعية تهديدا للموارد الطبيعية بالمغرب. ومن هذا المنطلق يروم الباحث في دراسته هذه، إلى بيان أثر هذه الظاهرة معتمدا على التباين الزمني والمكاني للبيانات المطرية على مستوى حوض تانسيفت خلال الفترة الممتدة من 1972 إلى 2015 من جهة، ودراسة ظاهرة الجفاف باستخدام سلسلة احصائية للتساقطات المطرية الشهرية المكونة من ثلاث محطات أرصاد جوية (أغبالو، شيشاوة، أدامنا)، وهي محطات تمثل الأجزاء الثلاثة للحوض (العالية ووسط الحوض والمصب). ومن جهة اخرى لقد اعتمدنا في تحليل الجفاف بالمنطقة المدروسة على تقنية مؤشر الموحد للتساقطات (Standardized Precipitation Index) محسوبة على عدة فترات زمنية. هذا سمح لنا بتوصيف تقلبات هذه الظاهرة، التي أصبحت أكثر وضوحا خلال العقود الماضية. أما على مستوى أهم النتائج، فقد لوحظ على طول المدة الزمنية المدروسة (1972-2015)، تباين مهم في فترات الجفاف بالمحطات المدروسة، فمثلا، لوحظت 08 فترات متوالية للجفاف بمحطة أغبالو، و11 فترة متوالية للجفاف بمحطة شيشاوة، ثم 09 فترات متوالية للجفاف بمحطة أدامنا.
الوسطية والاعتدال في الشريعة الإسلامية
Authors: وقار دل آقا , هاشمي سيد أحمد
Published: July 2023

يهدف هذا البحث إلی معرفة ميزات الإسلام الاعتدالية بين الأديان کما يتلألأ التوسط والاقتصاد في هذا الدين فی عباداته ومعاملاته وأخلاقه فالإسلام يأمرنا بالتوسط فی العبادات حسب الطاقة، هذا هو الاعتدال المطلوب فمثلا الصلوات الخمس التي لا تستغرق إلاّ الدقائق المحدودة السهلة، وكذلك الصوم لم يفرض علينا إلاّ مرة واحدة في السنة علی من لم يکن مريضا ولا مسافرا، وهو شهر رمضان المبارك. وكذلك الزكاة لم تفرض إلاّ على الأغنياء منا بشروط معتدلة خاصة. وكذلك الحج في العمر مرة واحدة لمن استطاع إليه سبيلا. الإسلام لا يمنعنا من التمتع بملاذ الدنيا من الأكل والشرب والنكاح وما شاكل ذلك من المباحات في حياتنا اليومية، إذاً الأخذ بالزينة المشروعة والاستفادة من الطيبات مطلوبة في شرعنا، فنحن برآء من الذين شوهوا صورة الإسلام الحنيف المعتدل، فواجبنا أن ندعو الناس إلى هذا المنهج الرباني المعتدل. الاعتدال والوسطية من ميزات هذه الأمة، فما دامت هذه الأمة، أمة وسط فلابد أن تمثل الاعتدال والوسطية في جميع ما يتعلق بحياتهم الأسرية (الشخصية) والاجتماعية، والسياسية، والأخلاقية، وإلا لخالفنا تسمية الله (المتوسط) لهذه الأمة والدين، وهذا لا يجوز قط. أما المنهج لهذه الدراسة فهو المنهج الوصفی المستفيد من المنهج التحليلي الذي يرکز علی الکتب والعکوف عليها قراءة ودراسة مع ذکر الأمثلة التطبيقية العملية. ومن خلال دراسة هذا الموضوع وثبوته بالأمثلة العملية الواضحة تتحقق النتيجة المطلوبة وهی أن الإسلام هو دين المتوسط حقا والمسلمون علی منهج الاعتدال تجاه الناس جميعا. ومن النتايج المطلوبة لهذه الدراسة هی أن التوسط ليس شعارا مجردا يردد بالألسنة دون التطبيق العملي، بل هو نظرية عملية تطبيقية ثابتة فی کافة المجالات الشريعة.

Analysis of state for the stocks of sockeye salmon ((Oncorhynchus nerka) from the Bolshaya River (western Kamchatka) in 1929–2022
Authors: Zaporozhets O. M. , Zaporozhets G. V.
Published: July 2023

The spawning stock of sockeye salmon in the Bolshaya River is evaluated for 1929–2022. Long-term tendencies are determined for their most important biological parameters, in particular, a juvenilization of returning spawners with decreasing of their body size, weight, and fecundity. Possible causes of these processes are considered. Biological indices of the sockeye salmon belonged to different races, ecological forms, ecotypes, and genders are compared statistically for different periods of time, with the frequency analysis. Changes in the size and age structure are revealed — range of the size and age variability has decreased. The age structure in the sea adjacent to the Bolshaya River mouth contradicts the hypothesis of a significant portion of sockeye salmon from Lake Kurilskoye in seine by-catch. The sockeye salmon abundance has changed periodically and recently is at the top of the wave. Compared to the 1929–2000 average, the stock has increased 6–7 times by 2020, and more than tenfold in 2022, whereas the average multiplicity of reproduction has increased 9 times (such a high value is obviously due to underestimation of spawning).
Patterns of linear growth and formation of annulus on scales of pacific herring in Peter the Great Bay
Authors: Chernoivanova L. A.
Published: July 2023

The data on linear growth and the scale annuli forming are generalized for pacific herring in Peter the Great Bay. The growth zone on scales begins in April-May, whereas the annuli of slow growth are formed from October to January. The phenological season of active somatic growth also starts in April-May for herring in this area, the largest gains of the body length are detected in late summer — early autumn, and the active growth ends by NovemberDecember. Size diversity for young fish depends on starting conditions of growth in the first year of life and the timing of puberty. The diversity increases for adults because of the growth accelerating for the fish dwelling in local favorable environments with longer growing season.
Aquaculture in the South of Russia

Published: July 2023

The strategy for development of agro-industrial and fishery complexes of the Russian Federation for the period up to 2030 focuses the domestic fish industry to increasing the volume of aquaculture products up to 618 thousand tons. With a proportional distribution of the regional load, the volume of seafood production in the Southern and the North Caucasian Federal Districts should be increased to 200 thousand tons by 2030. To achieve this level, the volume must increase by about 9 % annually that is almost 2.5 times higher than the actual gains. The problem can be solved with state support for development of large industrial farms that use warm wastewater from power plants or other industries. Further progressive development of aquaculture in the southern regions of Russia could be facilitated by creation of a state structure that provides practical interaction between enterprises, executive authorities, scientific and educational institutions.
Estimation of the maximum sustainable yield of giant grenadier Albatrossia pectoralis (Macrouridae) in the Russian Far East using Bayesian surplus production model JABBA
Authors: Kulik V. V. , Alferov A. I. , Goryunov M. I.
Published: July 2023

Statistical estimates for the exploitable stock of giant grenadier are determined, by fishing zones in the Russian Far East, and interannual dynamics of the species biomass is considered using historical data on catches and abundance. The assessments relationship with reference points of the biomass dynamic models is examined for the first time. With using the Bayesian approach, a priori assumptions about virgin biomass, which were made earlier on results of scientific surveys extrapolated to unsurveyed areas, are accounted in JABBA model; some errors in the catch and abundance indices are revealed. The parameters of instantaneous rate of recruitment and initial depletion of population are determined. Overfishing is not detected yet in any fishing zone, but a negative trend of the biomass dynamics is noticed for the Western Bering Sea fishing zone since 2015 (if the stock estimations based on surveys are realistic). The decline is reasoned by implementation of too high target for exploitation rate of vulnerable biomass (φF = 0.10) that is higher than such target for other fishing zones (< 0.08 or even 0.01 for the stocks exploited with the total allowable catch limits). That’s why annual catches exceeded the surplus production in the Western Bering Sea fishing zone in 2012 and since 2015 to nowadays. The sum of median estimations for the maximum sustainable yields in all fishing zones is about 47.4 . 103 t that exceeds the values of total annual catch. The instantaneous rate of recruitment is almost equal in the neighboring fishing zones in the western Bering Sea and at East Kamchatka (0.086–0.085 by median, with 95 % credible intervals from 0.05 to 0.14) and is much higher at Kuril Islands with the maximum in the North-Kuril fishing zone. The latter case is possibly conditioned by partially external recruitment. Therefore, population structure of giant grenadier should be clarified for correct modeling of the recruitment; until then, the stocks assessments by fishing zones are available.

Published: July 2023

Cobalt-based layered hydroxides (LHs) stand out as one of the best families of electroactive materials for the alkaline oxygen evolution reaction (OER). However, fundamental aspects such as the influence of the crystalline structure and its connection with the geometry of the catalytic sites remain poorly understood. Thus, to address this topic we have conducted a thorough experimental and in silico study on the most important divalent Co-based LHs (i.e.: ɑ-LH, β-LH and LDH) which allows us to understand the role of the layered structure and coordination environment of divalent Co atoms on the OER performance. The ɑ-LH, containing both octahedral and tetrahedral sites, behaves as the best OER catalyst in comparison to the other phases, pointing out the role of the chemical nature of the crystalline structure. Indeed, density functional theory (DFT) calculations confirm the experimental results which can be explained in terms of the more favourable reconstruction into active Co(III)-based oxyhydroxide-like phase (dehydrogenation process) as well as the significantly lower calculated overpotential across the OER mechanism for the ɑ-LH structure (exhibiting lower Egap). Furthermore, ex-situ X-ray diffraction and absorption spectroscopy reveal the permanent transformation of ɑ-LH phase into a highly reactive oxyhydroxide-like stable structure under ambient conditions. Hence, our findings highlight the key role of tetrahedral sites on the electronic properties of the LH structure as well as their inherent reactivity towards OER catalysis, paving the way for the rational design of more efficient and low-maintenance electrocatalysts.
Double-layer distribution of hydronium and hydroxide ions in the air-water interface
Authors: Zhang Pengchao , Feng Muye , Xu Xuefei
Published: July 2023

The acid-base nature of the aqueous interface has long been controversial. Most macroscopic experiments suggest that the air-water interface is basic based on the detection of negative charges at the interface that indicates the enrichment of hydroxides (OH–), whereas microscopic studies mostly support the acidic air-water interface with the observation of the hydronium (H3O+) accumulation in the top layer of the interface. It is crucial to clarify the interfacial preference of OH– and H3O+ ions for rationalizing the debate. In this work, we perform deep potential molecular dynamics simulations to investigate the preferential distribution of OH– and H3O+ ions at aqueous interfaces. The neural network potential energy surface is trained based on density functional theory calculations with the SCAN functional, which can accurately describe the diffusion of these two ions both in the interface and in the bulk water. In contrast to the previously reported single ion enrichment, we show that both OH– and H3O+ surprisingly prefer to accumulate in interfaces, but at different interfacial depths, rendering a double-layer ionic distribution within ~1 nm below the Gibbs dividing surface. The H3O+ is preferentially adsorbed in the topmost layer of the interface, but the OH–, which is enriched in the deeper interfacial layer, has a higher equilibrium concentration due to the more negative free energy of interfacial stabilization (–0.90 (OH–) vs. –0.56 (H3O+) kcal/mol). The air-water interface is therefore negatively charged, in agreement with the macroscopic charge detection and not in contradiction with the microscopic studies. The present finding of the ionic double-layer distribution qualitatively offers a self-consistent explanation for the long-term controversy about the acid-base nature of the air-water interface.
DFT Studies of Interaction between Methane and Single Metal Atoms: Co, Rh, Ir, Ni, Pd, and Pt
Authors: Mason Christian , Wang Lichang
Published: July 2023

Density functional theory (DFT) calculations were performed to study the interactions between methane and single atom of six metals, Co, Rh, Ir, Ni, Pd, and Pt. Understanding the metal initiated activation of C-H bonds is important as the metal-methane interaction can lead to the production of hydrogen molecules from methane as well as the detection of methane. The energies associated with the sigma interactions between methane and the metal atom were obtained with B3LYP. The different possible orientations and electronic interactions for each metal-methane interaction were analyzed and weighted using the population distribution to determine the average binding energy for the complex. The relative binding energies of each metal were compared and the metal with the greatest degree of binding is Palladium. The molecular orbitals were also analyzed to gain an understanding of how strongly the metal was interacting with methane. The distances between the atoms in the complex were studied to determine whether the interactions formed a sigma complex and the type of coordination the interactions formed.
De Novo Catalyst Discovery: Fast Identification of New Catalyst Candidates
Authors: Rasmussen Maria Harris , Seumer Julius , Jensen Jan Halborg
Published: July 2023

Very recently our group has demonstrated how a genetic algorithm (GA) starting from random tertiary amines can be used to discover a new and efficient catalyst for the alcohol-mediated Morita- Baylis-Hillman (MBH) reaction. In particular, the discovered catalyst was shown experimentally to be eight times more active than 1,4-diazabicyclo[2.2.2]octane (DABCO), which is commonly used to catalyze the MBH reaction. This represents a breakthrough in using generative models for catalyst optimization. However, the GA-procedure, and hence discovery, relied on two important pieces of information; 1) the knowledge that tertiary amines catalyze the reaction and 2) the mechanism and reaction profile for the catalyzed reaction, in particular the transition state structure of the rate determining step. Thus truly de novo catalyst discovery must also include these steps. Here we present such a method for discovering catalyst candidates for a specific reaction while simultaneously proposing a mechanism for the catalyzed reaction. We use the method to show that tertiary amines and phosphines are potential catalysts for the MBH reaction by screening a selection of 11 molecular templates representing common functional groups. The presented method relies on an automated reaction discovery workflow using meta-dynamics calculations. Combining this method for catalyst candidate discovery with our GA-based catalyst optimization method results in an algorithm for truly de novo catalyst discovery

Modern natural products (NPs) research relies on untargeted liquid chromatography coupled with mass spectrometry metabolomics. Together with cutting-edge processing and computational annotation strategies, such approaches can yield extensive spectral and structural information. However, current processing workflows require feature-alignment steps based on retention time which hinders the comparison of samples originating from different batches or analyzed using different instrumental setups. In addition, there is currently no analytical framework available to efficiently match processed metabolomics data and associated metadata with external resources. To address these limitations, we present a new sample-centric and knowledge-driven framework allowing multi-modal data alignment - e.g. through chemical structures, biological activities, or spectral features - and demonstrate its value in exploring large and chemodiverse natural extract datasets. Here, the experimental data is processed at the sample level, matched with external identifiers where possible, semantically enriched, and integrated into a unified knowledge graph. The use of semantic web technology enables comparison of processed and standardized data, information, and knowledge at the repository scale. We demonstrate the utility of the developed framework, the Experimental Natural Products Knowledge Graph (ENPKG), to leverage the results obtained from screening 1,600 plant extracts against trypanosomatids and streamline the identification of new antiparasitic compounds. Thanks to its versatility, the proposed approach allows for a radically novel exploitation of metabolomics data. Semantic web technologies are a fundamental asset and we anticipate that their adoption will complement the current computational metabolomics pipelines and enable the community to advance in the description of global chemodiversity and drug discovery projects.

Published: July 2023

Recent advances in native mass spectrometry (MS) and denatured intact protein MS have made these techniques essential for biotherapeutic characterization. As MS analysis has increased in throughput and scale, new data analysis workflows are needed to provide rapid quantitation from large datasets. Here, we describe the UniDec Processing Pipeline (UPP) for the analysis of batched biotherapeutic intact MS data. UPP is built into the UniDec software package, which provides fast processing, deconvolution, and peak detection. The user and programming interfaces for UPP read a spreadsheet that contains the data file names, deconvolution parameters, and quantitation settings. After iterating through the spreadsheet and analyzing each file, it returns a spreadsheet of results and HTML reports. We demonstrate the use of UPP to measure correct pairing percentage on a set of bispecific antibody data and to measure drug-to-antibody ratios from antibody-drug conjugates. Moreover, because the software is free and open-source, users can easily build on this platform to create customized workflows and calculations. Thus, UPP provides a flexible workflow that can be deployed in diverse settings and for a wide range of biotherapeutic applications.
Commercially Available Organolithium Compounds as Effective, Simple Precatalysts for Silicon–Nitrogen Heterodehydrocoupling
Authors: Reuter Matthew , Bushey Claire , Javier-Jimenez Diego , Waterman Rory
Published: July 2023

A family of commercially available organolithium compounds were found to effectively catalyze the heterodehydrocoupling of silanes and amines under ambient conditions. Ubiquitous nBuLi (1) was utilized as the benchmark catalyst, where an array of primary, secondary, and tertiary arylsilanes were coupled to electron-donating amines, affording aminosilanes in high conversions with short reaction times. Preliminary mechanistic analysis is consistent with a nucleophilic-type system. This study demonstrates one of the most straightforward methodologies for coupling silanes and amines under mild conditions, arguing for the use of commonplace organolithium reagents as routine catalysts for Si–N bond forming reactions.

Rare earth elements (REEs) have a crucial role towards low carbon green economy and clean society. A quarter of total global REEs production is used to produce permanent magnets which have high recycling value. In this study, a high-temperature oxidation process is used to selectively oxidize REEs in the magnet using Fe2O3 as an oxidizing agent. B2O3 is added as a flux to lower the slag melting temperature and for selective recovery of REEs. In this study, the effect of flux and oxidizing agent amount was investigated on both cerium-rich NdFeB and other NdFeB magnets. At 1350 °C for 1 h with the addition of 0.8 stoichiometric amount of Fe2O3 and 45 wt% of B2O3, the slag phase was successfully separated from the metallic phase primarily metallic iron. Microstructural analysis showed that REEs in the magnet did not report to the metal phase while the REE-rich slag phase contained almost no iron or other exogen elements. After the selective removal of iron, REEs were recovered from the slag through an acid-leaching process. The process proposed in this study is reagent and energy-efficient for NdFeB and NdCeFeB magnets as iron can be removed in the initial smelting step.
Gender and entrepreneurship amongst refugee women entrepreneurs in Glasgow, Scotland
Authors: Bikorimana Chanel , Nziku Dina Modestus
Published: July 2023

Background: Entrepreneurship studies reveal that despite significant progress made by women entrepreneurs, the gender gap in entrepreneurship is unlikely to be closed. It continues to be observed in both developed and developing countries, as many women-led businesses still face lower average business outcomes than male-owned businesses. This study investigates the impact of gender and entrepreneurship amongst refugee women entrepreneurs in Glasgow.

Research purpose: The aim of this study is to deeply understand how gender and entrepreneurship affect the motivation of refugee women entrepreneurs. To achieve this aim, three objectives were developed: (1) To understand the motivational factors that make refugee women become entrepreneurs. (2) To identify the key challenges faced by refugee women entrepreneurs in establishing their own businesses. (3) To provide recommendations for policy aimed at helping refugee women develop their entrepreneurial activities.

Methods: A qualitative study was conducted based on semi-structured face-to-face interviews with ten interviewees, involving six refugee women entrepreneurs and four mainstream agencies. Purposive sampling was employed in recruiting four participants, while two more were recruited through ‘snowball’ sampling. All interviews were audio-recorded, transcribed, and analysed using the Nvivo software. 1

Conclusions: The findings of this study revealed that refugee women entrepreneurs were motivated by both push and pull factors. Similar findings by Kone, Ruiz, Vargas-Silva (2019) indicated that refugee entrepreneurs have a greater tendency to start their own businesses due to positive factors such as greater entrepreneurial ambition, but also because of negative factors, such as lacking opportunities in the labour market due to discrimination. Finance was cited as the major barrier faced by all respondents, a situation which is shared by all entrepreneurs. However, refugee women entrepreneurs experienced other acute problems, such as a lack of access to the market, a lack of management skills, poor social networks, and a lack of family support.

The article is devoted to one of the aspects of the formation of domestic approaches to the development of tactical-forensic or tactical-psychological recommendations for interrogation in general, as well as recommendations in the structure of forensic methods for investigating certain types of crimes, based on the division of interrogation into two groups on the basis of the so-called , conflict/conflict-free interrogation situation. The article reveals different levels of understanding the conflict, and, consequently, understanding the conflict or conflict-free situation in which the investigative action takes place and the possible negative consequences of mixing these concepts, an erroneous idea of the current situation. In this regard, the main attention is paid to the ideas about the situation of conflict-free interrogation, as well as the signs on which the interrogation is supposed to be attributed to this group.

Published: July 2023

Poliovirus infection causes paralysis in up to 1 in 200 infected persons. The use of safe and effective inactivated poliovirus vaccines and live attenuated oral poliovirus vaccines (OPVs) means that only two pockets of wildtype poliovirus type 1 remain, in Afghanistan and Pakistan. However, OPVs can revert to virulence, causing outbreaks of circulating vaccine-derived poliovirus (cVDPV). During 2020–2022, cVDPV type 2 (cVDPV2) was responsible for 97–99% of poliomyelitis cases, mainly in Africa. Between January and August 2022, cVDPV2 was detected in sewage samples in Israel, the United Kingdom and the United States of America, where a case of acute flaccid paralysis caused by cVDPV2 also occurred. The Pan American Health Organization has warned that Brazil, the Dominican Republic, Haiti and Peru are at very high risk for the reintroduction of poliovirus and an additional eight countries in Latin America are at high risk, following dropping vaccination rates (average 80% coverage in 2022). Sabin type 2 monovalent OPV has been used to control VDPV2 outbreaks, but its use could also lead to outbreaks. To address this issue, a more genetically stable, novel OPV2 (nOPV2) was developed against cVDPV2 and in 2020 was granted World Health Organization Emergency Use Listing. Rolling out a novel vaccine under the Emergency Use Listing in mass settings to contain outbreaks requires unique local regulatory and operational preparedness.
