The purpose of this research is to determine The Legal Certainty of Waarmerking in Notarized Sale and Purchase Agreements: A Case Analysis of Civil Proceedings (Case research: District Court Decision No. 354/Pdt.G/2019/PN.Sda). The research employed in this research is normative research, drawing from literature studies. Data collection techniques involve an extensive literature review. The outcomes indicate that a waarmerking agreement possesses robust legal evidentiary authority in civil cases, contingent upon the parties acknowledging the signatures within the agreement. This is attributed to the fact that the function of waarmerking deeds under the hand primarily ensures the accuracy of the date in the registration of deeds under the hand in a dedicated book within the notary office. In the Sidoarjo court decision, the waarmerking of the binding agreement of sale and purchase, once waarmerked, is deemed valid and binding for both parties by the judge. However, it is noteworthy that the binding agreement of sale and purchase, serving as the foundation for the lawsuit, fails to meet the essential criteria for a valid agreement concerning the specification of "a certain thing." The subject matter pledged in the agreement has undergone a transfer of ownership to a different entity. Consequently, the binding agreement of sale and purchase in the Sidoarjo Court's civil cases lacks legal evidentiary force, as it is deemed to fall short of meeting the essential requisites of the agreement. This situation introduces legal uncertainty for other parties currently exercising control over the land and building.
Legal Validity Of Power Of Attorney To Sell Which Is Preceded By A Sale And Purchase Binding Agreement On The Transfer Of Land Rights (Sales And Purchases)

Published: May 2024

This research aims to examine and analyze the legal validity of the Power of Attorney to Sell, which is preceded by a Sale and Purchase Binding Agreement, in the implementation of the Deed of Sale and Purchase if the person giving the power of attorney dies. This research uses normative research methods, is perspective-based, uses a statue approach and a conceptual approach conceptual approach, and the types and sources of data used are primary legal materials, secondary legal materials, and tertiary legal materials. Data collection techniques are carried out through literature studies and interviews, and qualitative data analysis techniques are used. The results of this research show that the legal validity of the Power of Attorney to Sell, which is preceded by a Sale and Purchase Binding Agreement, in the implementation of the Sale and Purchase Deed if the person giving the power of attorney dies is still valid and legal, so that the buyer has legal certainty to carry out the Transfer of Land Rights with reference to the Deed of Sale and Purchase Agreement and Power of Sale. The power of attorney to sell given by the seller to the buyer is a power of attorney that cannot be withdrawn or terminated for any reason. So if all the requirements have been fulfilled, then the process of making a sale and purchase deed can be continued before the PPAT, and transferring the name of the certificate at the land office should proceed as it should even if the person giving the power of attorney (the seller) dies.
Prediction of Density in Standing Trees of Various Wood Species in Natural Forests Using Near-infrared Spectroscopy
Authors: Sofianto Imran Arra'd
Published: May 2024

Density plays an important role as basic information for applying wood as construction materials. Recent years, the application of near-infrared spectroscopy as non-destructive testing (NDT) has been promising. Density prediction for standing trees in huge variation trees and species of natural forest needs to be investigated using NDT as of eco-green harvesting. The combination of density information and near-infrared spectroscopy is enabled to build a prediction model. This research applied increment cores sampling for density prediction analysis using near-infrared spectroscopy method. The research combined increment cores samples from multiple wood species to be analyzed in one chemometrics analysis of cross-validation partial least squares regression (CV-PLSR) to build a prediction model of density.  The research resulted coefficient of determination for cross-validation (R2CV) of 0.76 with number of latent variable (LV) 10 from the 1st derivative with 13 smoothing-point spectra and wavelength of 1200 – 1800 nm as the best prediction model. The result seemed sufficient enough with those number of LV for this small tube wood sampling of increment cores from multiple wood species. This research proved that building a prediction model for multiple wood species is possible to be done.
Dizibilidades e visibilidades da colonização dirigida às margens da Transamazônica – Brasil, década de 1970
Authors: Menezes Soares Filipe
Published: May 2024

O artigo faz parte de uma pesquisa que procurou problematizar o que chamei de “Amazônia da Ditadura”. Nesse intento, defi ni a chamada política de colonização dirigida (assentamento de trabalhadores às margens da rodovia Transamazônica) como a política-síntese da ditadura na Amazônia. A seguir, apresento parte da história dessa colonização. Para tanto, dividi o miolo do artigo em dois tópicos: deslocamento e assistência. Cada tópico versa sobre uma ação da política de colonização. Ora, para ser executada foi necessário o deslocamento de trabalhadores para a região amazônica, sobretudo os advindos do Nordeste. De outro modo, para instalar esses trabalhadores foi preciso que o governo da época montasse um programa assistencialista naquelas localidades. Aqui, destacarei, em meio ao que chamo de assistência, os esforços relativos à educação formal dos colonos, seus fi lhos, crianças que chegavam à Amazônia em meio ao projeto desenvolvimentista do governo militar na década de 1970.
A tiktokização das narrativas orais: discutindo práticas caseiras de produção de memória em plataformas digitais
Authors: Santos Neto Valdemir Soares dos , Bressan Júnior Mário Abel
Published: May 2024

Neste estudo, buscou-se refl etir de que maneira os relatos orais podem ser compreendidos nas práticas caseiras de produção de memória, sobretudo, nos modos de produção e circulação desses registros no âmbito da cultura da convergência midiática. Tomamos, como delimitação do nosso objeto de análise, a plataforma de vídeos, TikTok. Notamos que a plataforma tem se tornado um subterfúgio para diversos usuários, funcionando como um local de memória. Para nortear essa discussão, adotou-se um tom ensaístico, utilizando um encadeamento de fatos empíricos que possibilitasse tecer determinadas provocações, de modo a pensar na democratização de processos e práticas de produção e circulação da memória em espaços convergentes. Neste trabalho chamamos atenção para um tipo particular de produção de memória: o relato de pessoas idosas sobre suas vivências. As balizas teóricas deste estudo se respaldam em um aporte teórico transdisciplinar, convergindo com os estudos sobre memória e convergência midiática. Com base na discussão articulada com os objetos apresentados, os autores acreditam ser necessário problematizar com mais densidade a questão das práticas caseiras de produção e circulação da memória, bem como os modos como o indivíduo produz e consome memória e compartilha suas lembranças, no âmbito das redes sociais.

As metodologias ativas rompem com o sistema antigo de ensino e aprendizagem. Retiram do professor o papel de único detentor do conhecimento e passam maior autonomia em um papel mais ativo para os alunos. As metodologias ativas permitem que o aluno possa construir o aprendizado de forma mais próxima de sua própria personalidade. Existem diversas formas de metodologia ativas, porém a escolhida nesta pesquisa é a Aprendizagem Baseada em Problemas. Esta metodologia ativa conta com uma situação-problema que irá permear o conhecimento, senso crítico e capacidade de reflexão ao aluno, ressaltando assim o papel ativo em seu processo de aprendizagem. Objetivou-se com esta pesquisa identificar na literatura acadêmica a utilização da Aprendizagem Baseada em Problemas e também objetivou-se compreender quais podem ser seus benefícios e desafios. A justificativa se deu pela relevância das metodologias ativas e pela possibilidade de problematização de uma forma de aprendizado baseada justamente em problemas. A metodologia adotada se deu pela revisão de literatura sistemática a qual foi adotado critérios de inclusão, exclusão e palavras-chave a serem utilizadas para o recolhimento do material. Os resultados apontaram para a identificação do uso da Aprendizagem Baseada em Problemas na área da saúde com cursos como medicina, enfermagem e psicologia, e também da área jurídica, sendo identificado um desafio quanto ao ressentimento dos alunos diante de situações-problemas, sendo este um desafio, todavia que pode ser sanado pela utilização das Tecnologias da Informação e Comunicação.

A integração das Tecnologias de Informação e Comunicação (TIC) no contexto educacional, destacou a presença crescente de dispositivos tecnológicos nas mãos dos alunos. Isso resultou em uma expansão das TICs além de limitações temporais e espaciais, tornando-se uma parte fundamental da vida diária dos alunos, educadores, pais e da sociedade em geral. A cultura digital promovida pelas TICs é ressaltada por potencializar novas formas de interação, mas também introduzir novos riscos, como o cyberbullying, roubo de dados e uso indevido de informações. A falta de conhecimento dos usuários das redes é apontada como um fator chave nesse contexto, ou seja, as TICs também apresentam riscos aos seus usuários, seja no âmbito pessoal e também no âmbito educacional. A pesquisa busca evidenciar riscos e desafios das TICs no contexto educacional apontados na literatura, principalmente em relação à segurança digital. A metodologia adotada envolve uma revisão sistemática da literatura, com critérios de inclusão e exclusão para selecionar artigos relevantes, resultando em uma compreensão mais profunda dos comportamentos de risco e desafios para os docentes. Justificado pelo fator que a identificação dos riscos e dos desafios permitem a elaboração de estratégias para superar os desafios e dirimir os riscos envolvidos. Os resultados apontam para o desafio, a insegurança dos docentes no manuseio das TICs e para os riscos envolvendo exposição de dados e imagem dos discentes.

Published: May 2024

Garantir acesso à educação de qualidade é um tema importante para toda comunidade universidade e também para a sociedade brasileira. Desafio diário de educadores em todo o país. Os alunos são diferentes e têm necessidades individuais, vivendo, portanto, uma realidade particular.  Nesse sentido, questiona-se: Qual a importância da família para o processo de aprendizagem escolar? A metodologia do estudo está centrada na pesquisa bibliográfica e exploratória com base nos pressupostos teóricos de autores que tratam sobre os problemas de aprendizagem e sua inter-relação no processo ensino-aprendizagem. Os resultados elencados demonstraram que é possível criar uma cultura de participação ativa, através de estratégias que possam ter como foco sensibilizar os pais dos alunos para tomarem parte direta das relações educativas mais participativas, estabelecendo os compromissos sociais tanto da escola como da família, para eliminar a crise de culpas e predominar entre uma articulação que possa ser benéfica ao desenvolvimento da escola e ao crescimento pessoal do educando. O objetivo central é discutir a importância da integração entre escola, família e sociedade no contexto do processo de desenvolvimento e aprendizagem da criança. Partindo do pressuposto de que este processo se relaciona, sobretudo com aquilo que a criança vivencia e estabelece dentro e fora da escola, o estudo propõe uma análise sobre o papel que o psicopedagogo tem de articular essas ações contribuindo para um maior envolvimento entre os educadores e os familiares. Para tanto, utiliza-se uma metodologia de pesquisa bibliográfica, baseada principalmente na revisão dos temas, a fim de demonstrar que a relação escola X família é imprescindível para a construção da identidade de um indivíduo, em especial para o desenvolvimento integral da criança.

Entrevistador: Olá, Dr. Paulo Freire. É um prazer tê-lo conosco hoje. Para começar, poderia nos contar um pouco sobre sua jornada e o que o inspirou a se tornar um educador? Paulo Freire: Olá, é um prazer estar aqui. Minha jornada como educador começou em minha infância no Brasil, onde pude testemunhar as desigualdades sociais e a falta de acesso à educação para muitos. Essas experiências despertaram em mim um profundo senso de justiça social e um desejo de promover a mudança através da educação. Foi essa inspiração que me levou a desenvolver meus métodos educacionais centrados na conscientização e na libertação. Entrevistador: Seus métodos educacionais são amplamente conhecidos e influentes em todo o mundo. Como você descreveria o cerne da sua abordagem? Paulo Freire: O cerne da minha abordagem educacional é a conscientização, ou "conscientização crítica", como costumo chamá-la. Acredito que a educação deve ir além da simples transmissão de conhecimento; ela deve capacitar os alunos a entender criticamente o mundo ao seu redor, questionar as estruturas de poder e trabalhar para transformar a realidade em que vivem. Isso envolve um diálogo horizontal entre educador e educando, onde ambos aprendem e se transformam mutuamente. Entrevistador: Seus conceitos de "educação como prática da liberdade" e "educação para a conscientização" têm sido fundamentais para muitos movimentos sociais e programas de desenvolvimento ao redor do mundo.

Published: May 2024

Abstract. The cloud condensation nuclei (CCN) activity of black carbon (BC) particles importantly determines their impacts on cloud microphysics and atmospheric lifetime. This process is crucially influenced by the number of hygroscopic coating materials that BC acquire during the ageing process. It remains a challenge for ambient measurements to capture this process and link this with CCN activity of BC. Here, we directly measured the droplet activation diameter (D50) and activation fraction of BC-containing (BCc) particles (Fact,BC) in suburban Beijing using coupled measurements of size-resolved number concentrations of CCN at configured water supersaturation (SS) and BCc particles. The number concentration of BCc particles was found to peak at diameter 180–210 nm after acquiring coatings, larger than that for all particles (50–150 nm). Consequently, the initially smaller BC particles become enlarged and more hygroscopic, thereby exhibiting CCN activities than other particles. The Fact,BC increased from 42 % to 69 % in number and from 67 % to 85 % in mass as SS increased from 0.1 % to 0.2 % but tended to reach a plateau when SS > 0.2 %. Notably, Fact,BC and D50 linearly correlated with equivalent photochemical age, at a rate of +2 % h−1 and −3 nm h−1, respectively. The results suggest BCc particles from anthropogenic sources can readily serve as CCN at a relatively low SS, and more than half of the BC population can be activated within a few hours, indicating that the surface-sourced BC can efficiently incorporate into clouds and potentially exert important indirect radiative impacts.

Abstract. During the mid-Pliocene warm period (mPWP; 3.264–3.025 Ma), atmospheric CO2 concentrations were approximately 400 ppm, and the Antarctic Ice Sheet was substantially reduced compared to today. Antarctica is surrounded by the Southern Ocean, which plays a crucial role in the global oceanic circulation and climate regulation. Using results from the Pliocene Model Intercomparison Project (PlioMIP2), we investigate Southern Ocean conditions during the mPWP with respect to the pre-industrial period. We find that the mean sea surface temperature (SST) warming in the Southern Ocean is 2.8 °C, while global mean SST warming is 2.4 °C. The enhanced warming is strongly tied to a dramatic decrease in sea ice cover over the mPWP Southern Ocean. We also see a freshening of the ocean (sub)surface, driven by an increase in precipitation over the Southern Ocean and Antarctica. The warmer and fresher surface leads to a highly stratified Southern Ocean that can be related to weakening of the deep abyssal overturning circulation. Sensitivity simulations show that the decrease in sea ice cover and enhanced warming is largely a consequence of the reduction in the Antarctic Ice Sheet. In addition, the mPWP geographic boundary conditions are responsible for approximately half of the increase in mPWP SST warming, sea ice loss, precipitation, and stratification increase over the Southern Ocean. From these results, we conclude that a strongly reduced Antarctic Ice Sheet during the mPWP has a substantial influence on the state of the Southern Ocean and exacerbates the changes that are induced by a higher CO2 concentration alone. This is relevant for the long-term future of the Southern Ocean, as we expect melting of the western Antarctic Ice Sheet in the future, an effect that is not currently taken into account in future projections by Coupled Model Intercomparison Project (CMIP) ensembles.
HGS-PDAF (version 1.0): a modular data assimilation framework for an integrated surface and subsurface hydrological model
Authors: Tang Qi , Delottier Hugo , Kurtz Wolfgang , Nerger Lars , Schilling Oliver S. , Brunner Philip
Published: May 2024

Abstract. This article describes a modular ensemble-based data assimilation (DA) system which is developed for an integrated surface–subsurface hydrological model. The software environment for DA is the Parallel Data Assimilation Framework (PDAF), which provides various assimilation algorithms like the ensemble Kalman filters, non-linear filters, 3D-Var and combinations among them. The integrated surface–subsurface hydrological model is HydroGeoSphere (HGS), a physically based modelling software for the simulation of surface and variably saturated subsurface flow, as well as heat and mass transport. The coupling and capabilities of the modular DA system are described and demonstrated using an idealised model of a geologically heterogeneous alluvial river–aquifer system with drinking water production via riverbank filtration. To demonstrate its modularity and adaptability, both single and multivariate assimilations of hydraulic head and soil moisture observations are demonstrated in combination with individual and joint updating of multiple simulated states (i.e. hydraulic heads and water saturation) and model parameters (i.e. hydraulic conductivity). With the integrated model and this modular DA framework, we have essentially developed the hydrologically and DA-wise robust toolbox for developing the basic model for operational management of coupled surface water–groundwater resources.

Abstract. Three seasonally resolved ice core records covering the 20th century were extracted in 1994, 2004, and 2012 at a nearly identical location from the Col du Dôme (4250 m above sea level, m a.s.l.; Mont Blanc, French Alps) drill site. Here, we complete and combine chemical records of major ions and radiometric measurements of 3H and 210Pb obtained from these three cores with a 3D ice flow model of the Col du Dôme glacier to investigate in detail the origin of discontinuities observed in the depth–age relation of the ice cores drilled in 2004 and 2012. Taking advantage of the granitic bedrock at Col du Dôme, which makes the ice core 210Pb records sensitive to the presence of upstream crevasses, and the fact that the depth–age disturbances are observed at depths for which absolute time markers are available, we draw an overall picture of a dynamic crevasse formation. This can explain the non-disturbed depth–age relation of the ice core drilled in 1994 and the perturbations observed in those drilled in 2004 and 2012. Since crevasses are common at high-Alpine glacier sites, our study points to the important need for rigorous investigations of the depth–age scale and glaciological conditions upstream of drill sites before interpreting high-alpine ice core records in terms of atmospheric changes.

Increasing the productivity of animals and birds, resistance to non-infectious and infectious diseases remains a priority in agricultural production. Currently, the problem of obtaining environmentally friendly animal feed and food of animal origin is acute. The main natural and anthropogenic pollutants of feed and food raw materials are mycotoxins, toxic elements and pesticides. It is important to highlight the role of the influence of combinations of natural and anthropogenic pollutants on a living organism. Mycotoxins, toxic elements and pesticides, in addition to their polytoxic effect on animals, significantly reduce product quality indicators. This article examines the organoleptic, physicochemical and microbiological parameters of broiler chicken meat during the experimental introduction of natural (T-2 toxin and deoxynivalenol) and anthropogenic (cadmium and diquat) ecotoxicants against the background of the use of modified bentonite. Experiments were conducted on 40 broiler chickens divided into 4 groups: group 1 - biological control, received the basic diet, group 2 – toxic control (broiler chickens received food contaminated with mycotoxins, cadmium and diquat); group 3 – broiler chickens received toxic feed with a modified sorbent; group 4 – control due to the harmlessness, broiler chickens with a basic diet received a modified sorbent. The duration of the experiment was 21 days. When assessing the organoleptic parameters, it was revealed that the meat samples of broiler chickens of groups 1, 3 and 4 correspond to the characteristic features of fresh meat, groups 2 – of questionable freshness. When evaluating the physico-chemical parameters of chicken meat of the second group, a significantly increased value of the pH level of muscle tissue, an increase in amino-ammonia nitrogen by 34.9%, the amount of volatile fatty acids, acid and peroxide numbers by 1.9, 3.4 and 5.0 times, respectively, was recorded relative to other experimental groups. The qualitative reaction to peroxidase in testing 1, 3 and 4 samples of chicken meat was positive, in 2 – negative. The contamination with cocci and sticks of smears-prints of the surface layers of the muscles of broiler chickens of the second group was recorded. The organoleptic, physico-chemical and microbiological parameters of broiler chicken meat against the background of the use of a modified sorbent did not differ significantly from those of the biological control group and corresponded to the characteristic features of fresh meat.
Arterial highways of the foot of the American raccoon (Procyon lotor)

Published: May 2024

The vascular system is one of the integrating systems of the human and animal body. The course and branching of the vessels of various areas of the body follows general patterns. However, the variability of the vascular bed is quite high even within a single species of animal. The lack of data on both the topography and the peculiarities of arterial branching makes it difficult to carry out diagnostic and therapeutic manipulations. In addition, the data obtained during the study significantly enrich the available information on the comparative anatomy of the vascular bed. The purpose of the study is to study the main arterial arteries of the American raccoon foot area, to give them a morphometric characteristic. The research was carried out on 4 corpses of an American raccoon, delivered to the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine from veterinary clinics. Classical methods were chosen as research methods: fine anatomical dissection, morphometry, photographing and vasorentgenography. During the study, it was found that two arterial highways are distinguished on the foot of the American raccoon. The dorsal trunk is represented by the dorsal artery of the foot, the plantar trunk is represented by the middle plantar artery. The dorsal artery of the foot passes into the arc artery – the first anastomosis that unites the vessels of the two highways. The middle plantar artery gives rise to the second and third plantar metatarsal arteries and participates in the formation of a deep plantar arch, which is the second major anastomosis of the foot area. Axial and non-axial finger arteries also form collateral blood flow. Analyzing the obtained morphometric data of arterial highways, it follows to conclude that the plantar surface highways have the largest diameter. Thus, the diameter of the middle plantar artery is 1.72 times higher than the same parameter of the dorsal artery of the foot. The largest total diameter is characteristic of the arteries located in the metatarsal region, the smallest in the area of the metatarsal.

Published: May 2024

The purpose of the studies was to substantiate the use of reduced concentrations of follicle-stimulating hormone to induce superovulation in highly productive cows and heifers. The research was carried out in one of the farms in the Leningrad region. After analyzing breeding cards and based on ultrasound visualization of the reproductive organs, promising animal embryo donors were selected - cows after the first calving and heifers that had reached physiological maturity, Holstein breed. According to the principle of analogues, groups of experimental animals Ⅰ and Ⅱ were formed, which included cows, and groups Ⅲ and Ⅳ, which included heifers, eight and six animals each, respectively. To induce multiple ovulation, hormonal treatment regimens were used, presented in Table 1. Hormonal treatment regimens were compiled in accordance with methodological recommendations on the procedure and conditions for applying the method of cattle embryo transplantation, as well as in accordance with the results of previously conducted studies and analysis of literary sources. As a result of the studies, it was established that all experimental animals responded equally to the hormonal regimen recommended by the manufacturer of exogenous gonadotropins and the experimental regimen, with a reduced concentration of the latter. It was revealed that there were no significant differences in the number of corpora lutea in the groups of cows and heifers when using a standard scheme for stimulating polyovulation and with a reduced content of follicle-stimulating hormone. There was also no difference between the experimental groups of cows and heifers in the number of embryos obtained. Analyzing the data obtained, we can conclude that it is advisable to use reduced concentrations of pituitary gonadotropins to stimulate multiple ovulation in highly productive cows and heifers.

Lymphoma (lymphosarcoma) is a malignant lesion of the lymphatic system. At the moment, cases of lymphoma among small pets have become more frequent. In this regard, literature data were studied and a chemotherapy protocol for dogs with lymphoma was developed. The study involved 20 companion dogs who were treated from September 2021 to September 2022. To make an accurate diagnosis, a history of life and anamnesis of animal disease was collected, computed tomography was performed to assess the extent of the lesion and the metastatic potential of lymphoma, and a biopsy was taken for histological examination. After receiving data confirming lymphoma, 10 companion dogs were prescribed a course of chemotherapy using the drugs etoposide, doxorubicin, vincristine, prednisolone (newly developed HOPE protocol), which were administered once a week for 19 weeks. In parallel, studies were carried out on 10 companion dogs during the same period of time, which were treated according to the well-known CHOP protocol, using cyclophosphamide, doxorubicin, vincristine, prednisolone, which is the standard treatment for lymphoma. According to the results of the study, we found that the median survival of dogs with lymphoma treated with the HOPE protocol was 302 days, and the life expectancy under the CHOP protocol was 235 days, while the animals experienced the occurrence of cystitis, polyuria and polydipsia, which was not manifested during treatment the HOPE protocol.

The report presents the results of acaricides using from the macrocyclic lactones group and complex drug administration which includes deltamethrin, diflubenzuron and piperonyl butoxide by psoroptic scab of cattle. There was research at the beefproducing farm (Aberdeen Angus breed). It was four groups (n=10 by each). Animals of the 1st experimental group have received «Meradoc» drug (doramectin 1%, subcutaneous introduction, the neck area), 2d experimental group – «Ivermec» drug (ivermectin 1%, 1 ml per 50 kg, subcutaneous introduction, the neck area), 3d experimental group – «Deltsid 7.5» by single dose (15 ml per 100 kg) by the application on skin vertebral from the head to the tail. The 4th group was control without acaricidal treatment. It was found the single using of macrocyclic lactones groups’ drugs were destroyed only the larval, nymphal and imaginal phases of acarian Psoroptes without ticks’ eggs extermination. The scraping was included ticks’ eggs on 7th day after «Deltsid 7.5» drug using, but it wasn’t detected any larval, imaginal phases and ticks’ eggs on the 14th, 21st and 28th days after beginning of animal’s treatment. Moreover, to the 28th days there were registered the hair restoration and the skin in affected areas without compaction and folding. The using of complex drug «Deltsid 7.5» is more effective treatment of psoroptic scab of cattle. This drug has the acaricidal effect on the preimaginal phases Acariformes. There were blocked the enzymes activity which destroy the drug’s effect. To take on the Acariformes resistibility by acaricides it should be control the quality of anti-acaricidal treatments by microscopy of skin scrapings. The recommendation in the case of the positive result’s getting is the treatment alternation.
Exploring the role of the facets of metacognition in the learning process of undergraduate students

Metacognition is the human capacity to monitor and control our own psychological activity. This capacity is fundamental for several processes that involve the individual being aware of this activity, e.g., learning. Building on a substantial body of theory, metacognition is recognized as one of the main components of learning and a key predictor of academic performance. Despite its acknowledged significance, the literature in the area has yet to explore the specific aspects of metacognition that explain all these relationships. Metacognition is not a unidimensional construct but rather a construct with three facets: knowledge about our own cognitive processes (metacognitive knowledge, MK), real-time monitoring and reflection on these processes (metacognitive experiences, ME), and the regulatory strategies we use to control them (metacognitive skills, MS). In light of empirical evidence highlighting the differences between these facets and their differential role over other processes, the relevance of investigating the individual and collective roles of the facets of metacognition in the learning process becomes apparent. To address this gap, we conducted two original studies. Our first study explores how MK, ME, and MS influence associative learning and academic performance in a sample of undergraduate students. The results show that, while academic performance is related to all facets, associative learning only depends on the quality of the individual's ME. A mediated effect of MK on learning through ME and a moderating effect of the use of MS on the relationship between ME and learning are also observed. Our second study investigates the impact of MK and ME on problem-solving skills within a collaborative context. While the results did not corroborate the main objective of the study, valuable insights were gained regarding the influence of ME on the use of collaborative strategies in the classroom. In summary, our studies affirm the idea that the facets of metacognition play different roles in the learning process and offer valuable information into their relationships within educational contexts.

Relevance: This article reviews a study that evaluates the effect of using anatomical region templates at the delineation stage on the quality of exposure plans. We compare two groups of plans: with and without the use of anatomical region templates. The study aims to optimize planning processes and compliance with standards. It is hypothesized that the use of anatomical region templates at the delineation stage may influence the efficiency and accuracy of radiation therapy planning.
Conclusions: the use of anatomical region templates greatly simplifies and speeds up the treatment planning process, allowing for increased productivity and more patients to be treated without sacrificing quality of care, as well as reducing the likelihood of missing structures, thereby ensuring safe treatment. The creation of anatomical region templates allows standardized procedures and dosage parameters to be established, thereby improving the quality and uniformity of radiation therapy. However, anatomical region templates can limit individualized treatment because they are based on standardized templates and may not take into account the unique characteristics of patients.
These results highlight the significant advantages of using anatomical region templates in radiotherapy planning, but also highlight the limitations of this method in individualizing treatment.

Purpose: The paper is devoted to the comparison of simultaneous (SIB) and sequential (SEQ) radiation therapy of primary-multiple tumors with different absorbed total doses based on the modeling of integral radiobiological criteria.
The research is aimed at optimization of treatment of rare primary-multiple tumors, development of optimal approaches based on the analysis of the effectiveness of different irradiation options.
Material and methods: This research considers a system of primary-multiple targets, using a gynecologic tumor including vagina (adenosquamous carcinoma), endometrium (moderately differentiated adenocarcinoma with foci of squamous metaplasia), and lymph nodes as an example, to which certain equivalent total doses of irradiation must be delivered (EQD2>=74.8 Gy for vagina, EQD2>=85 Gy for endometrium). Different scenarios of two-stage and one-stage irradiation, including different combinations and doses for each target, are studied in the simulation.
Results: Comparison of treatment plans for the triple target system shows that, performing sequential radiotherapy SEQ is characterized by higher levels of equivalent total dose delivered to the target volumes taking into account the total irradiation time and, consequently, to the critical organ volumes, especially in the rectum and sigmoid colon. In case of simultaneous irradiation SIB, the duration of treatment is five weeks instead of seven weeks, which reduces the value of the equivalent total dose to the target by 7-10 Gy. The value of the absorbed single dose delivered to the target volume is up to 3 Gy, which can be attributed to moderate hypofractionation. Levels of radiation exposure for critical organs in this case are much lower than when two-stage irradiation is used.
Conclusion: Simultaneous integrated boost radiation therapy allows a significant reduction in radiation exposure to critical organs compared to sequential radiation therapy (reduction to single systems).

Model Prediction and Optimization of Belt Drive System Vibration Suppression Based on Industrial Robot Joints
Authors: Bo Xu
Published: May 2024

Addressing the vibration issues caused by torsional angle changes in the belt transmission systems of industrial robots during practical applications, this paper introduces a control strategy that integrates a Model Predictive Control (MPC) compensation mechanism. By applying the Lagrangian method, a dynamic mathematical model correlating torsional angle and torque was established, and an algorithm design combining MPC with its compensatory controller was developed. This strategy was validated in a MATLAB simulation environment. Simulation results demonstrate that, compared to traditional sliding mode control, the newly proposed controller significantly improved response speed in tracking the torsional angle's position and angular velocity, achieving enhancements of approximately 2 seconds and 1 second, respectively. This led to higher tracking accuracy and faster convergence speed, effectively enhancing the vibration suppression performance of industrial robot joint belt transmission systems.
