Published: October 2024

In digital All Access is easy to do activities.Combining relations between parties in an international context is not an easy affair. It involves differing systems,views, and judgments that act as standards that must be adhered to by parties in different countries. Transacting in the context of international business at this time is not a difficult thing,because various technological advances have opened up huge opportunities for the international community to relate to each other. However, this ease can also cause various problems between them.International business is a convict state, where convicts grant broad freedom to the parties concerned to make, negotiate, and enforce the clauses they agree to. However, it is important to recognize that in order to carry out such business activities, the parties must carefully understand the rules of law in force in the opposing country. This will have a significant impact on the implementation of the agreement. Therefore, it is very important for researchers to clarify legal protections in international business transactions in the era of Free Trade. In payment by Telegraphic Transfer there are facilities and shortcomings, which deficiencies will be very bad both exporters and importers. There is another solution from the payment system other than Telegraphic Transfer, namely there is a Letter of Credit explained that the payment of this Letter of Credit equally guarantees its security to both parties, namely exporters and importers.

Published: October 2024

This study aims to analyze the factors influencing customer decisions in choosing Sharia Home Ownership Loans (KPR) at BTN Syariah KCPS Meulaboh, West Aceh. Using a quantitative approach and descriptive analysis method, this research involved 100 respondents selected through purposive sampling. Data was collected through structured questionnaires and analyzed using multiple linear regression with SPSS version 23.00. The results indicate that competitive margins and efficient application procedures have a positive effect on customer decisions. However, payment flexibility has a negative impact. Classical assumption tests show that residuals are normally distributed according to the Kolmogorov-Smirnov test, there is no multicollinearity, but there is an indication of potential heteroscedasticity in the payment flexibility variable. The resulting regression model can explain about 39.0% of the variability in customer decisions. This study provides valuable insights for BTN Syariah KCPS Meulaboh to improve their Sharia KPR services and products, focusing on competitive margins, streamlined application procedures, and a better understanding of customer preferences regarding payment flexibility.

Authors: Ramanda Dika , Achmad Fauzi  , Pakpahan Victor Maruli
Published: October 2024

Technological advances have given rise to the need for data protection, especially digital images, which are vulnerable to misuse. This research proposes a super encryption method that combines two cryptographic algorithms, namely Rabin Cryptosystem and Paillier Cryptosystem, to increase digital image security. Rabin's algorithm does not have homomorphism, so it is vulnerable to factorization attacks if the prime numbers used are too small. Meanwhile, the Paillier algorithm has homomorphism properties which allow arithmetic operations to be carried out directly on the ciphertext without decryption. By combining these two algorithms, this research aims to create a stronger and more efficient encryption method, and analyze its performance in terms of computational efficiency and complexity. It is hoped that the research results can improve the security and privacy of digital data, especially in the context of digital images.

The practice of coal mining has been demonstrated to exert a detrimental impact on the surrounding environment, particularly through the formation of acid mine drainage (AMD) ponds, which have the potential to pollute water sources. The reclamation of AMD is necessary to treat wastewater to ensure its safety for discharge into the environment and subsequent use as clean water. This study aims to treat AMD by comparing ultrafiltration (UF) and pervaporation (PV) processes utilizing silica-pectin multichannel membranes. The membranes were fabricated by coating silica-pectin sol on an inner surface of multichannel tubular support. The UF process was conducted under various pressures (1-3 bar), while the PV process was tested at various feed temperatures. Both permeate were collected and analyzed using several parameters (pH, Mn, and conductivity). The results showed that the UF process is more effective in collecting permeate flux over 136.6 L.h-1.m-2 at 3 bar pressure. Meanwhile, PV performs high permeate quality with Mn and conductivity rejection of 99.9 and 96.5%, respectively. Both UF and PV processes exhibit slightly increasing permeate pH with a range of 4.5-5.6. It concluded that multichannel silica-pectin membranes successfully reclamation AMD to enhance water quality. In addition, the UF process is more affordable for recycling AMD with high permeate flux, pretty good Mn, and conductivity rejection of over 95%.

Rickets, one of the leading causes of bony deformities and short stature, can be calciopenic (inciting event is defective intestinal calcium absorption) or phosphopenic (inciting event is phosphaturia). Early diagnosis and timely treatment of rickets are crucial for correction of the limb deformities. Guidelines exist for nutritional rickets, but the diagnosis and management of the relatively uncommon forms of rickets are complex. This consensus aims to formulate a simplified diagnostic approach for rickets, especially in resource-limited settings. The consensus statement has been formulated by a 29-member committee from the Endocrine Society of Bengal. The process included forming a working group, conducting a literature review, identifying controversies, drafting, and discussion at a consensus meeting. Participants rated their agreement with the clinical practice points, and a 70% consensus was required. Input integration and further review led to the final consensus statements. Children with suspected rickets should initially be examined for distinctive skeletal deformities. The diagnosis of rickets should be confirmed with characteristic radiographic abnormalities. It is advisable to order tests for serum calcium, inorganic phosphorus (Pi), liver function, 25-hydroxyvitamin D (25OHD), parathyroid hormone, creatinine, and potassium in all patients with rickets. In cases of refractory rickets, it is also recommended that assessments be conducted for spot urine calcium, Pi, creatinine, and, blood gas analysis. In children with rickets and metabolic acidosis, tests for glycosuria, uricosuria, aminoaciduria, low molecular weight proteinuria, and albuminuria should be conducted. In children with resistant calciopenic rickets and sufficient serum 25OHD levels, serum 1,25(OH)2D concentration should be tested. 1,25(OH)2 D and fibroblast growth factor 23 estimation is useful for certain forms of phosphopenic rickets.
Deciphering the mystery of CHNG3
Authors: Narumi Satoshi
Published: October 2024

Congenital hypothyroidism (CH), characterized by insufficient thyroid hormone production due to abnormalities in the hypothalamic-pituitary-thyroid axis, is the most common congenital endocrine disorder. We previously conducted comprehensive genetic screening of 102 patients with permanent CH born in Kanagawa Prefecture, Japan and identified mutations in several genes in 19 CH patients, including defects in genes encoding dual oxidase 2, thyroglobulin, thyrotropin receptor, thyroid peroxidase, and paired-box 8. Despite these findings, approximately 80% of cases remain unexplained. CH pedigrees unexplained by known genetic forms of CH have been reported in the literature and registered as congenital hypothyroidism, nongoitrous, 3 (CHNG3; %609893) in Online Mendelian Inheritance in Man. We also identified a Japanese pedigree of CH that was compatible with CHNG3. However, the exact genetic cause of CHNG3 was not revealed by standard analysis methods such as exome sequencing and array comparative genomic hybridization. We therefore took a combined approach and analyzed a total of 11 undiagnosed CH pedigrees by whole genome sequencing to analyze a 3-Mb linkage region, and found a disease-causing variant affecting a TTTG microsatellite in a noncoding region on chromosome 15. Further analysis revealed that 13.9% of 989 Japanese CH patients had abnormalities involving the TTTG microsatellite, with a substantial proportion (41.5%) of familial CH cases carrying these mutations. Identification of the genetic cause of CHNG3 provides new insights into the pathogenesis of CH, and highlights the need for continued exploration of noncoding genomic regions in Mendelian disorders of unknown etiology.

O atual momento do mundo é de mudança na faixa etária de sua população. A quantidade de idosos vem crescendo exponencialmente, ligada a esse fator, o número de enfermidades relacionadas diretamente à idade também apresenta-se elevado. O Parkinson é uma das doenças que frequentemente acometem os idosos no Brasil e no mundo. De acordo com os dados do Instituto Brasileiro de Geografia e Estatística , a expectativa de vida em 2017 é de 76 anos e com projeções que até 2040 a população de idosos seja aproximadamente de 17,41%.Na DP a principal manifestação clínica é a síndrome parkinsoniana, decorrente do comprometimento da via dopaminérgica nigroestriatal. A DP é a causa mais frequente de «parkinsonismo». Esta designação é fenomenológica e sindrómica, podendo surgir em várias patologias. O parkinsonismo caracteriza-se por: Tremor em Repouso, Um tremor rítmico que geralmente começa em uma das mãos quando está em repouso.O parkinsonismo ou síndrome parkinsoniana é um dos mais frequentes tipos de distúrbio do movimento e apresenta-se com 4 componentes básicos: acinesia, rigidez, tremor e instabilidade postural. Pelo menos dois desses componentes são necessários para a caracterização da síndrome. Na literatura Nacional pesquisada, não foram encontrados artigos que apresentassem resultados de estudos epidemiológicos de modo válido da doença de Parkinson. Os dados obtidos foram por meio dos portais de dados epidemiológicos do Governo brasileiro, os quais registram que no Brasil, não existem estimativas oficiais, mas o Brasil passa por uma transição demográfica com envelhecimento populacional. Isso leva à prevalência de patologias comuns da terceira idade. Segundo o IBGE , o número de homens e mulheres com mais de 60 anos aumentou 18% nos últimos cinco anos e, em 2017, somavam mais de 30 milhões. A DP possui origem desconhecida, entretanto alguns estudos indicam que ela pode ser ocasionada por um conjunto de fatores. Dentre eles, pode-se citar o, resultado de uma combinação da predisposição genética com a exposição a fatores tóxicos ambientais. Antes de se iniciar o tratamento para doença de Parkinson , é necessário que se tenha segurança quanto ao diagnóstico. O tratamento com drogas não pode abolir todos os sintomas, e Fisioterapia é então recomendada.

Tanto a produção quanto o consumo de leite e de produtos derivados de caprinos e ovinos têm apresentado crescimento no Brasil, embora, ainda, constituam pequenas quantidades em relação ao leite bovino. O leite dessas espécies tem um alto valor nutricional e é a opção para muitos consumidores que possuem intolerância a lactose do leite de vaca, além de apresentar uma boa digestão. O principal destino para o leite ovino e caprino é para produção de derivados, como queijo e iogurtes, que tem apresentado uma grande aceitabilidade por parte dos consumidores. A produção de leite caprino é a mais avançada, tem maior concentração no Nordeste onde se beneficia das regiões semiáridas, aproveitando a adaptabilidade dos caprinos. Enquanto a produção de leite ovino ainda é menor e é realizada por pequenas propriedades. Esta revisão teve como objetivo entender a cadeia produtiva da ovinocaprinocultura leiteira, focando no seu potencial, mercado e o consumo no Brasil.
The positive impact of corporate mergers on consumer welfare: from the perspective of corporate R and D investment
Authors: Li Muzi
Published: October 2024

Enterprise mergers are essential for the development and growth of enterprises, and they are also an important mechanism for the market economy to improve the overall efficiency of the market through the survival of the fittest. Compared to gradually growing a company through internal accumulation, merging with other companies can achieve various goals such as scale expansion, business expansion, and financial optimization faster in a short period. Although business mergers are spontaneous actions of enterprises, the merger of enterprises, especially large enterprises, affects their performance and consumer welfare. To better study the potential impact of corporate mergers, this article combines traditional and modern merger theories to investigate the positive effects of corporate mergers on product prices, corporate innovation, and overall consumer welfare. The impact channels of Chinese-listed company mergers on their R&D expenses are evaluated empirically. Through empirical and theoretical analysis, this article proves that business mergers can improve efficiency, innovation, and consumer benefits by increasing research and development expenditures.
Connectomics Investigation of Role of Parabrachial Nucleus Aversion using Optogenetics: A Experiment Proposal
Authors: Huang Lingyue , Li Yuxi , Liu Kechen , Zheng Yule
Published: October 2024

In recent decades, there has been a notable increase in research activity focused on the aversive and reward circuits of the brain. The evidence indicates that the parabrachial nucleus (PBn) is a crucial element in the generation of aversion responses in mice. Following successful stimulation of the PBn, mice display increased aversive and stress-related ehaviours. The study employs Fos TRAP2-ChR2 mice, opioids such as oxycodone, and a range of imaging technologies to monitor and manipulate neural pathways. Behavioral tests and optogenetic manipulation are used to assess real-time behavioral responses in mice, with the aim of uncovering the neural pathways and mechanisms involved in PBn-mediated aversion. Nevertheless, the underlying mechanisms of these behaviours remain unclear. The objective of this study is to investigate the connectomics of the parabrachial nucleus (PBn) in order to determine its association with regions involved in motivation, such as the nucleus ambiguus or the amygdala. It is hypothesised that this association may lead to aversion by affecting these regions. An alternative hypothesis is that if the parabrachial nucleus is connected to areas that are not directly related to it, it may be considered a motivational area in its own right. The identification of these connections will elucidate the underlying mechanisms of aversion mediated by PBn, thereby providing a deeper understanding of the neural basis of aversive behaviour and its regulation.

This work presents the findings of a study investigating the propagation of spin waves in a multiferroic structure comprising two periods, which is subjected to elastic deformations. Radiophysical measurements were employed to obtain data on the transmission and dispersion characteristics of spin waves at varying configurations of the external electric field applied to the piezoelectric layer. It was demonstrated that the formation of forbidden zones in the spectrum of spin waves and alterations in the transmission coefficient of spin waves are contingent upon the configuration of the electric field. The findings of this study can be utilized to develop a logic element of the NAND/NXOR type.
