An analysis of the environmental flexibility and stability of the varieties of potato made
it possible to distinguish 6 different groups among the middle-early and mid-ripening varieties. Flexible varieties (combining high yield and stability (having flexibility factor bi 1) and
their yield varies in accordance with changes in environmental conditions) are as follows:
Mayak (Ural Research Institute of Agriculture), Sadovy, Braslet, Ruchey (South Ural Research Institute of Agriculture), Yozhik, Terra-1 and Tustep (Kostanay Research Institute of
Agriculture). The varieties of intensive type include the varieties of the Chelyabinsk selection:
Itzil (1.94; 35.4), Tarasov (1.93; 84.4), Pamyati Kovalenko (1.74; 121.2), Spiridon (bi = 1.64;
Si2 = 28.8), Cavaler (1.33; 27.0) and Agat (1.25; 32.9). Neutral varieties (bi value is close to
zero). The varieties that weakly respond to changes in the environment: Raduga and Kuzovok (South Ural Research Institute of Agriculture), Irbitskiy (Ural Research Institute of Agriculture), Artem, Akzhar, Udovitskiy, Yagodniy 19 and Kostanayskiye Novosti (Kostanay Research Institute of Agriculture). The fourth group represents a highly productive (35.2 t/ha),
stable variety Alaya Zarya (Si2 = 5.3) of the Kazakh breeding with a negative regression coefficient (bi = –0.77), that provides guaranteed yield under extreme conditions. The fifth
group has the following varieties: Nevskiy and Chelyabinetz of high flexibility (bi = 1.40 and
1.80, respectively) and stability (Si2 = 6.8 and 14.2), but having relatively low productivity
(21.5 and 22, 2 t/ha). The sixth group includes stable varieties that respond weakly to changes
arising from the conditions of plant growing, but crop capacity is low: Gubernator (17.9 t/ha;
bi = 0.47; Si2 = 8.0), Balabai (22.3 t/ha; 0,26; 7.0) and Krasnopolskiy (17.6 t/ha; 0.70; 18.2).

The article analyzes the state of the crop production in the Far East and its territories for the
period 1991-2018. The formation of a permanent population in the region, the stability of society and
the solution of economic problems depends on the state of the agricultural production and the living
conditions of the rural areas. The research resulted in working out main directions of development
of the crop production providing necessary levels of production of agricultural products and raw
materials. In order to identify the efficiency of agricultural production in the Far East Federal District, we assessed the amount of material resources and investments to ensure the promising parameters of crop production industries. The efficiency of production was defined as the growth of production volumes per unit of land, funds and investments. On the basis of the regional methodology
of reproduction processes in crop production, designed for the period 2016 to 2025, taking into account the peculiarities of the bioclimatic potential of the Far East, the prospects for their development
in crop production were determined. Promising indicators will provide changes in agricultural production.
PRIORITY FIELDS OF PRODUCTION FOR PERSONAL CONSUMPTION AND INDUSTRIAL PROCESSING IN THE FAR EAST OF RUSSIA
Authors:   Far East Research Institute of Agriculture, Kiselev E.P.
Published: February 2025

When Far East Research Institute of Agriculture was founded in 1935 it set a goal to develop
technologies for cultivation and preservation of the crop under the conditions of overwetting. The theory of making ridges and beds as a form of the field surface, especially in the cultivation of vegetables and potatoes, was developed by V. V. Burlaka (in 1967). Complexes of units (machines) for
cultivation of plants on the crests of 70 cm, 90 cm and on the beds of 140 cm were developed by the
engineering staff of the Institute under the leadership of S. I. Gnedin. Main provisions of the complexes of equipment and technologies are presented in books published by the Institute in 1974 and
1979 (edited by Kazmin G. T.). This technology was approved by E. P. Kiselev at the Scientific and
Technical Council of the Russian Federation in 1979 and found application in the territories of the
Far East. In 1986 All-Russian Potato Research Institute proposed and patented its ridge technology
for the territory of the European part of Russia 110+15+15 cm, which came into use for cultivation
of this crop on the northern territories. In the Far East the scientists continued to test the technology
120+20cm. Under given climatic conditions of the territory, E. P. Kiselev developed the theory and
practice of creating varieties for wide-space sowing (patent No. 20.32.32. approved in 1995.) The
need to produce varieties for industrial processing has raised the problem of growing environmentally friendly potatoes. The specialists of All-Russian Potato Research Institute (V. N. Starovoitov, O.
A. Pavlov, year 2007) developed technology of cultivation of this crop using the region of plant alimentation 110+30, 120+20cm. This excludes the use of herbicides. Thus, it was a return to the technology developed by Far East Research Institute of Agriculture and to the theory of the creation of
varieties for wide-space sowing (E. P. Kiselev’s patent, year 1995).

The article presents the results of the assessment of 13 varieties of meadow clover using the
parameters of ecological flexibility, sustainability and adaptability under the severe northern conditions of the Kamchatsky Krai. Investigations were carried out during 2014–2018 in the experimental
field of the Kamchatka Research Institute of Agriculture. The calculation of indices of flexibility and
sustainability was carried out according to the method of Eberhart and Rassell, as presented by V.A.
Zykin. Calculation of the coefficient of adaptability was carried out by the method of L. A. Zhivotkov
with co-authors. The object of the research was early ripening and late ripening varieties of meadow
clover: Kudesnik, Martum, Kirovsky-159, Vityaz, Orpheus (Research Institute of Agriculture of the
North-East), SibNIIK-10, Atlant, Ogonyok (Siberian Research Institute of Feed), Smolensky-29,
Delets (Smolenskaya Agricultural Experimental Station), Hephaestus, Svetlyachok (Research Institute of Northern Zauralye), Komandor (Primorsky Research Institute of Agriculture). On average,
high yield potential in 5 years of use of the grass stand was recorded in early ripening varieties of
clover Martum (618 centners per hectare), Kudesnik (555 centners per hectare), late ripening varieties: Delets (623 centners per hectare), Svatlyachok (604 centners per hectare), Vityaz (578 kg / ha).
On the basis of the analysis performed, varieties SibNIIK-10 (bi – 1,2), Svetlyachok (bi -1,34) can be
attributed to varieties of intensive type. On the basis of the regression coefficient it is possible to
consider the following early maturing varieties to be flexible: Martum (bi – 0,99), Kudesnik (bi –
1,00), Smolensky-29 (bi – 0,94), Comandor (bi – 1,14); flexible late ripening varieties: Kirovsky-159
(bi – 0,90), Atlas (bi – 0,97), Ogonyok (bi – 1,01), Hephaestus (bi – 1,09) and Orpheus (bi – 1,14).
Late ripening varieties Delets (bi - 0.60) and Vityaz (bi - 0.68) showed low ecological flexibility. The
varieties Delets, Martum, Svetlyachok, Vityaz, Orpheus and Kudesnik are characterized by a high
degree of adaptability being under specific cultivation conditions. All the varieties of meadow clover
under study show unstable behavior (Si² – 99,47–118,13–207,07) under the conditions of the Kamchatsky Krai.

An important condition for the effectiveness of technological solutions is modern complex
mechanization. Assessment of the effectiveness of crop cultivation is given in accordance with agrotechnical criteria. The indicators of agrotechnical efficiency of agricultural enterprises are given in
comparison with the indicators of the Amur Region based on the analysis of their production activities
taking into account the technologies of cultivation of grain crops and soybean. The generalized indicator of crop cultivation efficiency according to agrotechnical indicators in the Amur Region in 2012-
2017 amounted to 0.61 for grain, 0.63 for soybean. At basic agricultural enterprises, it exceeds the
average regional indicators by 57 - 64% for grain crops and by 44 - 73% for soybean. Increasing the
efficiency of crop cultivation is facilitated by an increase in productivity, as well as high quality
products, compliance with optimal agrotechnical schedule, the quality of technological operations,
and the positive environmental impact of technological-machine systems on the soil.

The article describes the advantages and disadvantages of mobile feed distributors using
auger (conveying worm) and beater as working members. It has been determined that when using
feed distributors with beater and auger type working members, a more uniform distribution of feed
components in the hopper of the distributor helps to increase the uniformity of the feed mixture and
reduce the unevenness of its delivery (distribution). In this case, the distribution of the mixture components along the length of the hopper has the greatest influence. The aim of the research is to theoretically identify the relationship between the heterogeneity of the obtained feed mixture, the unevenness of its delivery to animals and the instability of the flow coming out of the distribution organ of
the loader, as well as the uniform (even) distribution of feed components along the length of the
distributor hopper and the number of layers of feed collars formed in the hopper. Analytical dependence was found to determine the influence of uniform distribution of feed components along the
length of the distributor hopper (ratio of feed components in the hopper sections) on the process of
their mixing. Theoretically it was established that there is a dependence of the index of uneven distribution of feed in the hopper of the distributor on the number of layers of the collar formed in the
hopper. It was found that the more layers of feed components in the feed hopper, the less uneven
should be the distribution of feed in the hopper of the distributor and, so the less uneven be the distribution of feed to animals.
INFLUENCE OF L-THEANINE ON GROWTH INDICATORS AND THE BIOCHEMICAL STATUS OF BLOOD IN WEANLING PIGS AGAINST THE BACKGROUND OF OXIDATIVE STRESS
Authors:   Far East State Agricultural University, Maksimov N.I. , Lashin A.P. ,   Far East State Agricultural University
Published: February 2025

This study examined the effects of L-theanine on growth, antioxidant ability, and immune
function of weaned piglets with oxidative stress. To do this, weaned piglets weighing 7.53 kg ± 0.51
kg were selected, which were divided into 3 groups: control group (generally accepted diet, without
the addition of premix and L-theanine); 1 experimental group (common diet, with the addition of
premix, without L-theanine), 2 experimental group (common diet, with the addition of premix and
1000 mg of L-theanine per 1 kg of feed). The preparatory period was 7 days, and the experimental
period was 28 days. The results showed that the average daily weight gain and daily average feed
intake in the first group were significantly lower than in the second and third experimental groups,
while the ratio of feeding to weight was significantly increased. The average daily weight gain in 3
experimental groups of piglets increased significantly compared with the control and 2 experimental
groups. The content of malondialdehyde in the blood serum of the control group of piglets increased
significantly, while the total antioxidant ability and activity of glutathione peroxidase decreased significantly. The serum malondialdehyde of piglets of the first experimental group was significantly
reduced, while the antioxidant ability was significantly increased, compared with the control. The
content of malondialdehyde in the blood serum of piglets of the third experimental group significantly
decreased, while the antioxidant ability and activity of glutathione peroxidase significantly increased
compared with the control and the first experimental group, while the level of serum immunoglobulins and interleukins in both groups were significantly increased. Further, the indices of serum immunoglobulins and interleukins were compared in all experimental animals; in the control group, these
indices were significantly lower compared to the first and second experimental groups. The results showed that, against the background of oxidative stress, there is a decrease in growth rates and suppression of humoral and cellular immunity. However, when 1000 mg L-theanine per 1 kg of food is
added to the diet, it can significantly reduce oxidative damage to piglets and improve their growth
rates against the background of oxidative stress, which in turn directly affects the antioxidant ability
and the functioning of humoral immunity.

One of the urgent problems of intensive development of animal husbandry is the reduction
of the incidence of young farm animals, among which the leading place belongs to pathologies of the
gastrointestinal tract. Modern methods of keeping and breeding animals require that manufacturer
should achieve a rapid increase in production in the shortest possible time, which leads to the emergence of stressful conditions of the body. Such phenomena in young cattle can be prolonged and
permanent as a result of early weaning, transfer to artificial feeding, which ultimately leads to a violation of the imbalance of the intestinal microflora and the emergence of enteritis of various etiologies. To achieve food safety of livestock products, modern biotechnological developments suggest
using enzymatic probiotic drugs as a preventive measure against enteritis of calves. The effectiveness
of such feed additives for the prevention of gastrointestinal pathologies in young cattle has been clinically proven by domestic and foreign authors. The use of these drugs helps to normalize the intestinal
microflora, maintain enteral homeostasis and, as a result, increase the immune reactivity of the body.
Biological active feed additive «Vitacell « belongs to the group of biologically active metabolites
containing live vegetative cells and spores of microorganisms of cellulolytic, probiotic and prebiotic
action. The inclusion of probiotic “Vitacell” in the diet of young cattle helps to stimulate metabolic
processes in the body, increase feed conversion, and improve clinical and biochemical blood parameters. Thus, in the experimental group, hemoglobin and red blood cell indices increased by 37.6%
and 45%, respectively, against the background of a 21.6% decrease in the number of white blood
cells and reached the physiological norm in calves of this age group. Scientific and economic experiment was conducted at Priamurye Co., Ltd. of the Tambov District, Amur Region; object of research:
calves of black-and-white breed. The aim of the research was to study the effect of the enzymatic
probiotic «Vitacell « on the restoration of homeostasis and normalization of the hematological status
of the body during the lactation period, as well as on the growth of young cattle.

The addition of various dosages of protected vitamin B4 (0.8; 1.0; 1.2 g / kg of milk) to
fresh cows of the experimental groups in the first phase of milk stimulation period contributed to an
increase in the average daily milk yield of 4% fat content, respectively, by 5.5; 7.1; and 6.2% in
comparison with the control. The content of somatic cells in the average daily milk samples of cows
of experimental groups receiving various dosages of protected vitamin B4 was at the level of 176.2-
196.7 thousand or by 22.8; 37.1 and 33.3 % less in comparison with the animals receiving control feed. Using different doses of protected vitamin-B4 in the diets of fresh cows of experimental groups
during the first lactation phase allowed cows to increase the digestibility of all nutrients: in comparison with control animals. Feeding cows of experimental groups with different doses of protected
vitamin B4 helped to increase the digestibility of the diet feed, which is related to the indicators of
rumen digestion. Fortification of feed ration of fresh cows in the first phase of lactation with a protected vitamin influenced the intensity of protein, fat, carbohydrate, energy, mineral metabolism and
immunity characteristics of animals. In the chymus of cows receiving different dosages of protected
vitamin B4, there was an increase in the number of volatile fatty acids, protozoa, and bacteria, respectively-by 6.4-11.3; 24.1-48.3 and 9.5-28.6 %%, in comparison with the control variant, which
indicates a deeper hydrolysis of carbohydrates. The profit received from the use of vitamin B4 in a
protected form in the rations of cows during the period of stimulation of milk productivity amounted
to 3120 rubles per head.
¿Acciones afirmativas o privilegio? Análisis de las reacciones en la prensa sobre la suspensión de la prueba de aptitud académica en el Instituto Tecnológico de Costa Rica, en 2020
Authors: Campos-Chavarría Benjamín
Published: February 2025

El objetivo de este artículo es analizar las manifestaciones surgidas durante noviembre de 2020 ante el cambio en el proceso de admisión al Instituto Tecnológico de Costa Rica, manifiestas en el medio periodístico La Nación, y problematizarlas a la luz de los conceptos de ignorancia blanca de Charles W. Mills, injusticia epistémica de Miranda Fricker, apartheid educativo, espacio y privilegio de Shannon Sullivan, expansividad ontológica y, en menor medida, otros referentes teóricos de Sarah Ahmed y Achille Mbembé. Producto de la pandemia, en 2020 se sustituyó la prueba de aptitud académica por un mecanismo basado en las notas de presentación, el cual dividió a las personas postulantes en grupos según su tipo de institución secundaria de procedencia. En el texto se toman en cuenta 15 artículos publicados en los catorce días siguientes al anuncio público de los resultados de admisión, entre el 10 y el 23 de noviembre, para realizarles un análisis crítico del discurso. Se determina que en la mayoría de esas reacciones se presenta una imagen negativa del estudiantado de nuevo ingreso 2021, acusaciones de socialismo y daño al país, entre otras, que hacen poca justicia a lo realmente sucedido. Se detalla cómo en estas manifestaciones se ignoran las desigualdades y dificultades históricas de algunas poblaciones para acceder a los cupos de mayor demanda en las universidades públicas al competir en condiciones desiguales con otras poblaciones económica o socialmente privilegiadas.

Authors: Gómez Ramírez Luis Fernando , Abril Castro Jorge Leonardo , Cañas Álvarez Jhon Jacobo
Published: February 2025

Contextualización: el biol es un abono orgánico líquido, basado en la fermentación anaerobia de la materia orgánica, que actúa como fuente de nutrientes y microorganismos, estimulante del desarrollo vegetal y mejorador de la calidad del suelo. Su aplicación en pasturas podría contribuir a incrementar la producción de biomasa y reducir la fertilización química y el impacto negativo sobre el suelo.
Vacío de conocimiento: existe un desconocimiento por parte de productores de la región Caribe de Colombia en cuanto al aprovechamiento de coproductos como el estiércol animal para la producción de fertilizantes orgánicos, y los beneficios de su aplicación en pasturas para mejorar la nutrición de los suelos y promover la producción de forraje.
Propósito: el objetivo de este estudio fue evaluar el efecto de la aplicación de biol sobre el crecimiento y la calidad nutricional de pasto Guinea (Megathyrsus maximus cv. Tanzania) bajo condiciones del Caribe seco colombiano.
Metodología: se aplicaron cinco tratamientos al momento del corte de la pastura, bajo un diseño en bloques al azar con tres replicas: testigo sin fertilización (T1), fertilización edáfica con urea (50 kg N/ha) (T2), fertilización foliar con biol mineralizado al 5% v/v (T3), fertilización foliar con biol mineralizado al 10% v/v (T4) y fertilización foliar con biol mineralizado al 5% v/v más 50% de fertilización con urea (25 kg N/ha) (T5). Al final del ciclo se evaluó la altura de plantas, cobertura, producción y calidad de forraje, así como variables edáficas. Los datos fueron analizados con el paquete estadístico SAS 8.3 (8.3.0.103).
Resultados y conclusiones: los resultados mostraron que T2, T3, T4 y T5 incrementaron el porcentaje de cobertura, altura, rendimiento de forraje verde y forraje seco de la pastura con respecto al testigo (P<0.05). Las plantas tratadas con T5 mostraron resultados similares a T2 (P>0.05) en los diferentes parámetros evaluados. En la calidad de la pastura, carbohidratos solubles, %P, %K y %S presentaron diferencias entre tratamientos (P<0.05). La fertilización con biol podría ser una alternativa que permita mejorar parámetros de crecimiento en Megathyrsus maximus cv. Tanzania. y disminuir la fertilización química sin afectar significativamente los rendimientos y la calidad de la pastura.
Perception of family environment, sibling relationships, and life satisfaction: Effects of gender and birth order
Authors: Adamov Nikola , Prijic Jelena , Milovanovic Ilija
Published: February 2025

The perception of early experiences in the family of origin and sibling
relations can significantly shape life satisfaction. Considering the
different roles influenced by birth order and gender, examining the
predictive power of perceived family environment and sibling relationships
in the context of subjective well-being seems crucial. This retrospective
study explored the relationship between the perception of family support and
organization, the quality of sibling relationships, and life satisfaction.
The study included 642 participants, with an average age of 24.16 years, who
had grown up/were growing up in families with one sibling, i.e., brother or
sister. Life satisfaction was assessed using the Satisfaction with Life
Scale, while the Block Environment Questionnaire was used to measure support
and organization within the nuclear family. Sibling relationships were
measured using the Sibling Relationship Questionnaire. The main findings of
this research indicate that there are specificities in the assessment of the
family environment, the quality of sibling relationships, and life
satisfaction in the context of gender and birth order. Perceived experiences
of family support were a stronger predictor of life satisfaction among
individuals who grew up in brother-brother dyads or dyads where the brother
was older than the sister. Lower levels of conflict and rivalry were
determinants of life satisfaction in sister-sister dyads and dyads where the
sister was older than the brother. The results of this study support the
postulates of the Family Systems Theory and the tend-and-befriend theory.
The research implications are directed toward early preventive programs in
the context of family and individual counseling.

Efficient control of low inductance brushless DC motors based on LC filtering and active damping
Authors: Mehdi Allagui , Mohamed Abbes
Published: February 2025

Brushless DC motors (BLDC) present several technical advantages with respect to conventional permanent magnets synchronous motors. These advantages include higher rotational speeds, reduced construction complexity and simpler control strategies. This paper discusses a cost-effective control strategy for BLDC motors characterized by low stator inductance. The proposed technique is based on an LC filter inserted between the inverter output and the motor. The filter capacitors are controlled such that three DC voltages are applied to the stator terminals. An active damping approach is used to control stator currents and prevents voltage oscillations. Compared with existing solutions, this technique simplifies the hardware implementation of such a drive system and offers a notable reduction in the switching frequency with minimal values of the magnetic elements. In addition, high frequency torque ripples are significantly reduced. The design procedure of this controller is presented in this paper and the performances are compared with the conventional control technique.
The Concept of Dignity in International Law
Authors: Szymaniec Piotr
Published: February 2025

The first aims of the article is to trace the origins of the notion of human dignity in international law. It is emphasized that the concept of human dignity appeared in international law relatively late, in 1940s. and such concepts as “principle of humanity” or “laws of humanity”, used in the 19th century, are not identical with and do not even have to include human dignity. Moreover, a very different concept of “dignity of sovereign states” existed in international law from Vattel’s time until the 20th century. Nowadays, human dignity appears in international law as a value, legal principle and law. However, the right to dignity is less often explicitly mentioned in international law documents than the principle of human dignity. The minimum content of human dignity appears to include the recognition of the intrinsic value and moral autonomy of every human being.

Authors: Dobiáš Petr
Published: February 2025

Currently, the emphasis in international commercial arbitration is on the speed and efficiency of arbitration proceedings in order for international commercial arbitration to maintain its position in resolving disputes in international trade. The article is based on the hypothesis that the need for permanent arbitral courts to remain competitive with state courts, whose proceedings are expedited at the national and EU level by legislation on summary proceedings, leads them to use instruments guaranteeing efficiency and speed in international arbitration. The subject of the analysis and comparison carried out in the article are recent amendments to the arbitration rules of selected permanent arbitration courts and a critical assessment of their applicability in legal practice. In particular, it compares the regulation of the preparation of the hearing of the dispute, consolidation of arbitration proceedings, on-line arbitration, remote oral hearing, and expedited proceedings.

The purpose of the study. To determine the choice of the method of temporary hemostasis in patients with facial skull injuries resulting from road accidents.

Materials and methods. The work is retrospective, the sample is continuous, based on the analysis of the results of 230 patients with facial skull injuries having both isolated and/or combined injuries sustained in road accidents in the Saratov region from 2010 to 2021. The average age of patients was 29±5 years (M±m). There were 159 men (69,1%) and 71 women (30,9%). Medical histories, outpatient cards, and accompanying sheets of the ambulance team were used as primary documentation. The study included all patients who were delivered by ambulance crews, who had open and closed, isolated, multiple and/or combined injuries to the facial skull resulting from road accidents, starting at the age of 15. Patients with combined injuries of the extremities, cervical spine, pelvis, as well as patients who were not delivered by ambulance crews were excluded. Isolated injuries were detected in 58,6% of the victims, combined and multiple — in 41,7% of people. In the majority of observations — 72,6% — medical care at the prehospital stage was provided by medical teams of emergency medical care, such assistance was provided by paramedic teams only in 27,4% of observations. The time of delivery of the wounded to the medical institution from the moment of injury was on average 27±8 minutes (M±m). At the time of admission, open injuries were registered in 34,4% of people, patients with closed injuries of the facial skull prevailed — 65,6% of the victims.

Results. As a result of the study, it was found that all victims with such injuries can be conditionally divided into three groups, depending on the mechanism of injury: venous bleeding prevailed in the first group — in 6,9%, arterial bleeding was noted in 0,9% of cases, and capillary bleeding — in 3,9%. In the second group, bleeding was distributed as follows: capillary bleeding prevailed — in 13% of cases, arterial bleeding was noted in 2,6% of cases, and venous bleeding — in 4,3%. In the third group, capillary bleeding was detected in all 2.6% of cases. Based on this, the main method of temporary hemostasis was the imposition of a pressure bandage, which was applied in 23,5% of cases, in another 3,5% of cases, an anterior nasal tamponade was used to stop bleeding, in 7,4% of cases, a clamp was applied to stop bleeding. Of the total number of hemostases performed, as can be correctly characterized in 29,6% of cases, which was manifested by stopping bleeding. At the same time, in 4,8% of cases, the method of temporary hemostasis was not chosen correctly, which was manifested by continued bleeding at the time of delivery of the victim to a medical institution.

Monitoring crops ensures global, regional, and national food security. It entails gathering information such as the health and growth of crops and environmental conditions. This aids farmers in making well-informed decisions, enhancing productivity, and reducing environmental impact. This, in turn, leads to improved economic outcomes and long-term agricultural sustainability. In arid and semi-arid lands, effective crop monitoring is particularly critical due to the limiting factor of water availability. This study used Sentinel-2 (S2) image collection in Google Earth Engine (GEE) to mapping crop types in North Darfur State, Sudan during the 2022 growing season (July 1 to September 30, 2022), using support vector machine (SVM) and random forest (RF) classifiers. Eight vegetation indices (VIs), i.e., normalised difference vegetation index (NDVI), enhanced vegetation index (EVI), soil-adjusted vegetation index (SAVI), green-normalised difference vegetation index (GNDVI, weighted Difference vegetation index (WDVI), red edge NDVI (NDVIre), ratio-vegetation index (RVI), and normalised difference infrared index (NDII) were used as additional bands. The results show that the RF models produced an overall accuracy (OA) of 90-97% with a kappa coefficient (κ) of 0.87-0.96. The SVM models reported OA and κ values in the range of 84-95% and 0.81-0.94, respectively. Producer’s (PA) and user’s accuracies (UA) were in the range 83-97% and 81-98%, respectively. Highest F1 scores for both classifiers were 0.98. The findings of this study, along with the derived classification maps, would enable farmers, policymakers, and other stakeholders to make well-informed decisions regarding agricultural production, land use planning, and resource management in North Darfur and arid environments.

Published: February 2025

The Covid-19 pandemic has significantly impacted the tourism sector, leading to a drastic decline in regional revenue derived from this industry. To accelerate the recovery of the tourism sector, reliable forecasting methods are required to estimate tourist arrivals. This paper presents the use of time series SARIMA and Triple Exponential Smoothing (Holt-Winters) methods to predict the number of international tourist arrivals in the post-pandemic period. The analysis reveals that the SARIMA method with ARIMA (2,0,1)(1,0,1)₅ parameters, which accounts for seasonal trends over a five-month period, provides the most accurate predictions. Evaluation is conducted using MAPE, MAE, and RMSE value. The predictions generated by these methods are expected to assist governments and tourism-related industries in developing promotion strategies, infrastructure planning, and optimal resource allocation.

Point of Sale (POS) systems are essential for modern businesses, streamlining transactions, inventory management, and customer interactions. However, traditional POS systems face challenges such as limited real-time data processing, scalability issues, and restricted integration capabilities. This study proposes a RESTful API-based POS system using Supabase and Express.js to overcome these limitations.The system is developed using a hybrid waterfall methodology, combining structured phases with iterative refinement, and employs a relational database normalized to the third normal form (3NF) for data integrity and scalability. Supabase, as a backend-as-a-service platform, simplifies backend operations with its robust features for database management, authentication, and real-time APIs. Meanwhile, Express.js provides a lightweight and efficient framework for developing RESTful APIs, ensuring seamless integration and efficient data handling. Comprehensive testing, including black box testing, confirms the system’s reliability, ensuring its readiness for real-world implementation. The results highlight the system’s ability to enhance operational efficiency and adapt to dynamic business requirements. This study demonstrates how integrating RESTful APIs, Supabase, and Express.js can modernize POS systems, providing scalable, secure, and efficient solutions tailored to the demands of a data-driven marketplace.

We have repurposed the Huisgen rearrangement towards a multicomponent synthesis of 2-amino-1,3,4-thiadiazoles and 2-amino-1,3,4-oxadiazoles. The starting materials – 5-sustituded-1H-tetrazoles, TCDI or CDI, and amines – are readily accessible and allow for modular construction of heterocyclic scaffolds. To demonstrate the enabling aspect of this transformation towards late-stage modification of medicinally relevant molecules, we have prepared a thiadiazole-containing crisaborole derivative.

Published: February 2025

Pyridine derivatives are valuable components of biologically active compounds, materials, and ligands; however, traditional methods for site-selective direct functionalization are often hindered by multistep procedures and harsh conditions. Herein, we report a streamlined approach for the selective C4-alkylation of pyridine derivatives under electroreductive conditions using alkyl bromides. The addition of chlorotrimethylsilane significantly enhanced the yield and regioselectivity, and mechanistic studies revealed that the reaction involves a temporary dearomatization step, yielding a 1,4-difunctionalized intermediate, which then re-aromatizes upon air exposure. This method is scalable, mild, and highly selective, and demonstrates a broad substrate scope and good functional-group tolerance. In addition, C4-alkylated pyridines can undergo a subsequent electroreductive ortho-alkylation under standard conditions. This stepwise strategy allows the sequential incorporation of distinct alkyl groups through the selective use of different alkyl bromides at each stage, providing a versatile strategy for accessing structurally diverse di- and trifunctionalized pyridines.

Published: February 2025

Alkylamines are crucial structural motifs found in 43% of pharmaceuticals, where they interact with biological targets such as receptors and enzymes. Consequently, C–H functionalization of alkylamines serves as a powerful strategy for accelerating drug development. Especially, remote C–H functionalization enables selective modification of the periphery of the active nitrogen site, improving bioactivity and pharmacokinetics properties. While remote functionalization of primary and secondary alkylamines is well-established, analogous transformations of tertiary amines remain highly challenging, despite their prevalence in 60% of alkylamine-containing pharmaceuticals. This study unveils the new reactivity of α-ammonio radicals, a class of distonic radical cations, to achieve g-selective functionalization of tertiary amines. Our approach leverages halomethylammonium salts as precursors to α-ammonio radicals, facilitating precise radical transfer to the g-position. The resulting g-radicals enable a diverse range of gamma-selective functionalizations, including thioetherification, amination, alkylation, (hetero)arylation, and alkenylation. This method offers a broad substrate scope and facilitates late-stage functionalization of complex pharmaceutical molecules, highlighting its potential for drug development. Furthermore, this research expands the synthetic utility of distonic radical cations, broadening the methodological landscape for selective radical transformations and inspiring future advancements in radical chemistry.

Published: February 2025

The discovery of new chemoselectivity with readily accessible chemicals is important to expand the reaction space for modern chemistry. For dienes and dienophiles, most people will naturally use them to carry out the classic Diels-Alder reaction to construct six-membered cyclic compounds. Here, we demonstrated a chemoselective coupling of butadiene with dienophiles through a stereoselective 1,3-cyclotelomerization. By utilizing robust Ni/IPr catalysis, valuable bicyclic products were created with high regio- and chemoselectivities under mild conditions. Asymmetric cyclotelomerization enabled by chiral NHC ligand was also performed, generating enantioenriched bicyclic compounds. Mechanistic studies reveal that the reaction might start with oxidative cyclometallation between two molecules of 1,3-diene and Ni(0) species, which then undergoes [3+2]-cycloaddition via an electron transfer process. The products can undergo a variety of intricate transformations, which emphasizes the potential applications of this strategy. It is hoped that the discovery of this protocol will further inspire people to rethink the classic organic reactions.

As self-driving labs become widely deployed in chemicals and materials research, interest in democratizing access to these platforms is growing. SDLs can be democratized by lowering their costs to increase accessibility and by creating systems that allow researchers to modify, extend, and share SDL tools to meet the needs of their science and contribute to the advancement of the SDL community. In particular, user-developed automation infrastructure is an important component of democratized SDL ecosystems. To advance community adoption of democratized SDL practices, we organized the “Democratizing Self-Driving Labs” workshop held at the 2024 Accelerate conference. As part of this workshop, the authors contributed to a demonstration of their user-developed automation infrastructure. 14 examples of custom built hardware, software, and workflows were shared. This workshop provided an opportunity for researchers to see user-developed infrastructure in action, learn about how they could integrate these projects into their work, and contribute to discussion about what is needed to advance the state of democratized SDLs. In this perspective, ten contributed examples of user-developed hardware and software from the workshop are highlighted. Despite a diverse array of projects, common motivations for pursuing user-developed infrastructure were cost savings and specification requirements that were unmet by commercially available products. Continuing to advance the state of user-developed automation infrastructure will require commitments to completing high-quality documentation for open-source hardware projects, pathways for materials researchers to learn hardware development skills, and more opportunities for researchers to share their infrastructure advancements, in addition to the scientific advancements that they enable.
