В данной работе методом молекулярной динамики с использованием потенциала сильной связи исследовались биметаллические наночастицы Au - Co трёх стехиометрических составов различного размера. Установлены закономерности структурообразования, описаны их характерные особенности. В частности, в составах с 50ат.% и 75ат.% содержанием Au образуются множественные малые ядра локальной икосаэдрической симметрии. Только в составе Co -25ат.% Au с увеличением размера частиц преобладают кристаллические фазы. Выявлены составы, в которых внутренняя симметрия наночастицы определена наличием одного икосаэдра, либо сверхструктуры из нескольких икосаэдров. Рассчитаны концентрационные зависимости энергии смешения биметаллической наночастицы Au - Co. Показано, что в определённом диапазоне размеров существуют концентрационные составы, при которых биметаллический наносплав может проявлять нестабильность. С использованием калорических кривых потенциальной части внутренней энергии определены температуры кристаллизации. Установлено, что температура кристаллизации демонстрирует умеренный, либо существенный, в зависимости от состава, рост с увеличением размера биметаллических наночастиц Au - Co.
This work studied bimetallic Au - Co nanoparticles of three stoichiometric compositions of various sizes by the molecular dynamics method using the tight-binding potential. The regularities of structure formation are established, their characteristic features are described. In particular, in compositions with 50at% and 75at% Au content, multiple small nuclei of local icosahedral symmetry are formed. Crystalline phases prevail only in the Co - 25 at% Au composition with an increase in the particle size. Compositions are revealed in which the internal symmetry of a nanoparticle is determined by the presence of one icosahedron or a superstructure of several icosahedrons. The concentration dependences of the mixing energy of a bimetallic Au - Co nanoparticle are calculated. It is shown that there are concentrations of compositions at which bimetallic nanoalloys can exhibit instability in a certain size range. Crystallization temperatures were determined using the caloric curves of the potential part of the internal energy. It was found that the crystallization temperature demonstrates a moderate or significant, depending on the composition as well as growth with an increase in the size of bimetallic Au - Co nanoparticles.

Порошки наноразмерных гидроксиапатита и фторапатита синтезированы методом осаждения из растворов. В качестве связующего вещества использован пищевой желатин. Такая композиция имеет высокую адгезию на материалах различной природы и пористости. Получены также пористые пленки и гранулы с развитой удельной поверхностью. Рассмотрены их микроструктуры. Изучена возможность использования коллоидной суспензии и водной суспензии кристаллического апатита в сочетании с раствором желатина в качестве биоактивного материала, как для создания покрытий, так и получения гранул. Установлено, что использование порошка апатита совместно с желатином позволяет существенно сократить сроки формирования биоактивного покрытия и значительно повысить его адгезионную прочность. Сопоставлены получаемые гранулы апатита по размерам в зависимости от концентрации желатина в водном растворе. На разработанные биоактивные покрытия и гранулированный материал на основе наноразмерного апатита со связующим агентом поданы заявки на патент.
Nanoscale hydroxyapatite and fluorapatite powders were synthesized by precipitation from solutions. Food gelatin is used as a binder. This composition has a high adhesion on materials of different nature and porosity. Porous films and granules with a developed specific surface area were also obtained. Their microstructures are considered. The possibility of using a colloidal suspension and an aqueous suspension of crystalline apatite in combination with a gelatin solution as a bioactive material, both for creating coatings and obtaining granules, has been studied. It is established that the use of apatite powder together with gelatin can significantly reduce the time of formation of a bioactive coating and significantly increase its adhesive strength. The obtained apatite granules are compared in size depending on the concentration of gelatin in an aqueous solution. Patent applications have been filed for the developed bioactive coatings and granular material based on nanoscale apatite with a binding agent.

Аморфные, нанокристаллические мембранные сплавы на основе элементов V группы с уникальными механическими и функциональными свойствами и с матричной дуплексной микроструктурой активно способствуют развитию водородной энергетики. Имеются еще не вполне разрешенные проблемы для этих новых сплавов -их низкая термическая стабильность, недосточная механическая прочность (пластичность, твердость), а также охрупчивание интерметаллидное и гидридное. Для эффективного применения разрабатываются сплавы с тройным составом - в которые помимо элементов V группы входят и легирующие металлы никель и титан. Получают не только аморфные и нанокристаллические сплавы, применимые в электронике и электроэнергетике, а также мембранные сплавы с дуплексной матричной структурой, объединяющей аморфные, так нано- и квазикристаллические дендритно упрочняющие фазы, как упрочняющие аморфную матрицу. В специализируемых мембранных тройных сплавах формируются соединения NiTi и NiTi, стабилизирующие и предохраняющие нано- и кристаллические мембраны от хрупкого разрушения. Установлено, что интенсивное образование гидридов в этих альтернативных мембранных сплавах столь же не желательно, как и для традиционных сплавов на основе палладия. Рассматриваемые сплавы действительно позволяют получить газообразный водород высокой чистоты с применением новых составов взамен дорогостоящих мембран на основе сплавов Pd - Au / Ag / Cu.
With unique mechanical and functional properties, amorphous, nanocrystalline and matrix duplex microstructure membrane alloys based on group V elements actively contribute to the development of hydrogen energy. There are still not completely resolved problems for these new alloys - their low thermal stability, insufficient mechanical strength (plasticity, hardness), and intermetallic and hydride embrittlement. For effective use, alloys with a triple composition are being developed - which, in addition to the elements of group V, also include nickel and titanium as alloying metals. Not only amorphous and nanocrystalline alloys are obtained that are applicable in electronics and power engineering, as well as membrane alloys with a duplex matrix structure that combines amorphous, nano-and quasicrystalline dendritic-hardening phases strengthening the amorphous matrix. In specialized membrane ternary alloys, NiTi and NiTi compounds are formed, which stabilize and protect nano-and crystalline membranes from brittle destruction. It has been found that the intense formation of hydrides in these alternative membrane alloys is as undesirable as for palladium-based compounds. The alloys under consideration actually make it possible to obtain high-purity gaseous hydrogen using new compositions instead of expensive membranes based on Pd - Au / Ag / Cu alloys.
O poder judiciário como ator político na transição brasileira: um objeto de pesquisa a ser explorado
Authors: Gomes de Lima Camila 
Published: December 2021

O poder judiciário é um verdadeiro protagonista da vida pública brasileira. A questão que se coloca é: qual o papel que o poder judiciário tem cumprido no Brasil? Há um déficit de informação a respeito do poder judiciário. Produzir informações sobre essa instituição, seu passado e seu presente, é um caminho importante para compreender a complexidade de um sistema de justiça que afirma direitos e ao mesmo tempo promove sua violação. Assim como ocorreu com a ditadura e os processos por crimes políticos, há um vasto registro documental sobre a atuação do poder judiciário na democracia pronunciando-se a respeito do passado autoritário e seu legado de violações, para além das suas negativas de dar prosseguimento Ã s ações penais. Trata-se das referidas demandas por reparação, que compõem um vasto acervo documental que registra a atuação do poder judiciário como ator político na transição brasileira, para além de seus silêncios e negativa de levar adiante os processos criminais. Ao menos dois caminhos parecem interessantes para estudar a judicialização da reparação: pesquisa quantitativa, através do mapeamento das experiências de judicialização da anistia política e estudos de casos emblemáticos da judicialização da reparação, sendo esta última dotada de grandes potencialidades.

Abolicionismo penal? Mas qual abolicionismo, "cara pálida"?
Authors: Góes Luciano 
Published: December 2021

Os discursos abolicionistas que brotam em nossa margem, de modo geral, ignoram o racismo como ideologia, fazendo eco ao abolicionismo escravocrata que manteve a Casa Grande intacta ao modular toda sua arquitetônica racista dentro da democracia monocromática. Assim, mantêm os privilégios recebidos como herança de um mundo projetado e construído branco por mãos negras, perpetuando o racismo na exata medida de seu silenciamento. Um abolicionismo penal brasileiro deve retomar o projeto de emancipação racial oitocentista, fincado em base afroespistêmica para romper as profundas barreiras do nosso apartheid, sob pena de transformar-se em um novo instrumento do sistema de controle racial/social, remodelando, novamente, a exemplo das prisões, as Senzalas, e aniquilando os Quilombos.

Authors: Javier Yearson Diego , Melendez Ignacio , Anain Federico , Siniscalchi Santiago , Drago Juan 
Published: December 2021

Introducción: el hallux valgus es la deformidad musculoesquelética más frecuente. La laxitud y la hipermovilidad tarso metatarsiana favorecen su desarrollo. El objetivo de este trabajo es plantear una patología tridimensional, y elaborar un algoritmo quirúrgico para cada patrón de deformidad, incorporando el componente rotacional del metatarsiano.
Materiales y métodos: evaluamos prospectivamente una serie de 89 casos entre febrero de 2020 y febrero 2021, 80 mujeres y 9 hombres. Nivel de evidencia IV. La edad promedio fue 39 años y el seguimiento 11.3 meses. Utilizamos la clasificación de Hardy-Clapham y separamos 2 grupos, los hallux sin componente rotacional (tipo 1 a 3), y aquellos con componente rotacional (tipo 4 a 7).
Resultados: el 59% entraron en el primer grupo, a los cuales se realizó osteotomía distal en chevron acorde a la deformidad en el plano frontal. El 41 % restante tuvo componente rotacional, y se realizó una osteotomía distal en chevron rotacional, crecientica en la base, o artrodesis de Lapidus modificada, según la deformidad en plano frontal o inestabilidad asociada. Consolidaron todos pacientes. AOFAS 94.5%, VAS 0.71 y 100% de satisfacción.
Discusión: el componente rotacional es fundamental en la interpretación del hallux valgus, pero no es el único para tener en cuenta. El mismo puede no estar presente o no ser trascendente, y se alcanzan excelentes resultados como los publicados por décadas. Es fundamental diferenciar los pacientes con componente rotacional para realizar el tratamiento adecuado.
Conclusión: considerando el hallux valgus una patología tridimensional, proponemos un protocolo de tratamiento acorde para cada paciente.
Knowledge pattern assessment of potential safety threats of compact fluorescent lamps in Kuwait
Authors: Alsanad Abdullah , Almutairi Azel , Alhelailah Heba 
Published: December 2021

Globally, compact fluorescent lamps (CFLs) are increasing consistently, and Kuwait is not an exception. However, these lamps contain mercury, which is highly injurious to human health and the environment. This study assessed Kuwaiti respondents' awareness using a large-scale national survey conducted on a random sample of 6210 individuals (response rate 84.3%). The questionnaire was comprised of four sections and utilized skip logic branching. The modes were paper-based, face-to-face interviews, and electronic structured questionnaires. Data were also analyzed through the Pearson chi-square test to know the significant differences in lamp type preferences and the reasons for the preferences. Almost half of the participants (51.4%) knew the difference between incandescent and fluorescent lamps. Only 11.1% were using incandescent lamps solely in their houses. The remaining 88.9% used fluorescent lamps (38.4%) or both types (50.5%). The results showed that 48.3% think fluorescent lamps save energy, whereas 81.3% of people were unaware of their mercury content. The knowledge patterns towards breakage showed that respondents who chose the proper response were 31.9% for evacuation, 14.6% for aeration, and 7.3% for turning off the AC. The awareness of populations to take appropriate actions towards proper disposal was very poor in case of fluorescent lamp accidental breakage or when it completes its life cycle because most of them did not know about the proper evacuation, aeration, and cleanup measures. These findings are beneficial for the government and policymakers to take essential steps to create relevant awareness channels among the country's communities for safety from expected health hazards.

Nitrogen and boron are necessary for the metabolic activities of rice for its growth. With this perspective, a field experiment was conducted in farmer’s field during 2020 at Kuttalam, Mayladuthurai district, Tamilnadu in sandy clay loam(Padugai Series – TypicUstifluvents) to predict the response of rice (Oryza sativa) to different levels of nitrogen(N) and boron (B) application. The treatments consisted of Factor A- Nitrogen levels, 0, 75, 150, 225 kg ha-1 and Factor B- Boron levels 0, 1.5, 3.0 kg ha-1. Fifteen treatments were conducted in a Factorial randomised block (FRBD) design with three replications. The test crop was rice with a variety ADT 46. Concerning nitrogen alone, the highest grain (5344 kg ha-1) and straw yield was recorded in N3(225 kg ha-1). Among the boron levels tested, the highest grain (4695 kg ha-1) and straw yield (6509 kg ha-1) was registered in B1 (1.5 kg ha-1) in rice. The highest total nutrient uptake viz., N(88.2 kg ha-1), P(30.5 kg ha-1), K(105.0 kg ha-1) and B(172mg kg-1) were recorded in N3B1. Among the N alone, the highest total nutrient uptake viz., N(78.1kg ha-1, P(26.3kg ha-1), K (95.8 kg ha-1) and B(156.6 mg kg-1) in N3. Concerning B alone, the highest nutrient uptake viz., N(60.5, kg ha-1) , P(17.8kg ha-1) K(74.9 kg ha-1) and B(112.1mg kg-1) were registered in B1 over other B levels. The highest grain (5631 kg ha-1) was recorded in N3B1 (225 kg N ha-1 and 1.5kg B ha-1) than other interactions. The study concluded that applying nitrogen and boron is required to achieve the maximum yield of rice in sandy clay loam soil.
A pragmatic approach for analysis of long-term climate trends for apple growing regions of Himachal Pradesh, India
Authors: Arundhati  , Bhagat R. M. 
Published: December 2021

The study assessed the long-term climate as well as the area and production trends for four representative decades (1985-2020) in three apple growing districts of Himachal Pradesh, India with the objective of understanding the impact of climate change on apple crop. A long term database was prepared for minimum temperature (Tmin), maximum temperature (Tmax) and rainfall, besides area and production for four decades for three districts of Himachal Pradesh, India. Trend analysis indicated that the temperature in apple growing regions of generally showed an increasing trend, whereas, decreasing trend was observed in the precipitation. The minimum temperature in apple growing regions of Kullu, Shimla and Kinnaur districts has shown an increase of 0.82º C, 1.09 º C and 0.03 ºC, respectively and the precipitation (rainfall) in the Kullu, Shimla and Kinnaur districts has shown a decrease by 5.3 mm, 3.3 mm and 0.9 mm, respectively. Increased warming in the mountain regions is elevating temperatures resulting in the reduction of chilling hours, pre-requisite for apple fruiting. However, in the higher elevation of Shimla, Kullu and Kinnaur districts, in spite of the increase in temperature, the areas are still suitable for apple farming. The study indicated that the area and production of all three districts of study are increasing because growers are slowly shifting to low chilling varieties (Varieties having chilling hours requirement less than 1000 hours). Also, the present ecosystem at lower elevations will not support high chilling requirement varieties and apple growers will have to shift to either low chilling varieties or alternate crops.

Metabolically associated fatty liver disease is a widespread disease (MAFLD).The main treatment strategy for MAFLD is the correction of metabolic factors, changes in lifestyle, normalization of body weight, which is achieved by the use of diet therapy and physical activity.The purpose of this review is to present the characteristics of diets that have been studied in the treatment of patients with MAFLD.Results. The greatest evidence base on the effectiveness of treatment of MAFLD and the safety profile is the use of the Mediterranean diet and the diet with a low glycemic index. Patients should be advised to reduce their sugar intake, reduce their intake of saturated fatty acids and trans fats, and increase their intake of dietary fiber. Eating a balanced, calorie-restricted diet can help to provide healthy lifestyle and healthy eating habits, which are essential for the prevention and treatment of MAFLD. Hereditary factors, the composition of the intestinal microbiota, comorbid pathology can affect the results of diet therapy, which emphasizes the urgent need for an individualized approach in the treatment of this disease.
