Authors: Matysiak Wiktor P.
Published: September 2020

Kodeks spółek handlowych nie zawiera żadnej regulacji dotyczącej zaskarżenia uchwał wspólników spółek osobowych. Takie uchwały mogą być jednak sprzeczne z prawem, godzić w interesy spółki lub mieć na celu pokrzywdzenie wspólnika. Mogą być one uznane za dotknięte nieważnością w rozumieniu art. 58 kodeksu cywilnego Tego rodzaju uchwały mogą być przedmiotem kontroli sądowej w drodze powództwa o ustalenie nieważności uchwały. Celem niniejszego artykułu jest udzielenie odpowiedzi na pytanie o dopuszczalność takiego powództwa i jego przesłanki.

Published: September 2020

Ouvir uma voz é sempre uma experiência intensa e plena de sentidos que vão muito além das palavras cantadas ou faladas. O campo sonoro de uma voz, em que predomine a entoação ou o canto, tem opoder de transportar o ouvinte para um lugar de recepção emotiva que torna possível a cada um, mesmo através de uma experiência coletiva, como um grande show de rock, percorrer um caminho em direção ao mais profundo de sua individualidade e aí fazer emergir um denso conteúdo emocional. Há alguns autores como Barthes1, Cavarero2, El Haouli3 e Zumthor4, que nos falam sobre essa potência simbólica das vozes no contexto que vai muito além das palavras.

Aim: Wine quality is influenced by the nitrogen nutrition of grapevines in the vineyard. A deficiency of this nutrient will affect grape quality, decrease yeast available nitrogen (YAN) and influence alcoholic fermentation. Chasselas wines from nitrogen-deficient grapes (YAN < 140 mg N/L) are systematically more astringent and bitter and less fruity than those from grapes with higher YAN content (Spring et al., 2014). The aim of this study was to identify chemical markers in wine linked to nitrogen deficiencies in the vineyard.Methods and results: Wine samples produced from grapes growing in nitrogen-deficient vineyards with nitrogen treatment (HN) and without it (LN) were used over four consecutive years (2006–2009). They were all analysed at the same time (2012) with electronic-nose, GC-MS and UHPLC-TOFMS techniques. A metabolomics approach was used for a comprehensive survey of volatile and nonvolatile compounds in order to identify markers related to nitrogen nutrition. Volatile markers with alcohol and ester functions and nitrogen-containing compounds were found and tentatively identified by GC-MS. Additionally, 16 nonvolatile markers were putatively identified by UHPLC-TOFMS, including compounds from diverse chemical classes, namely, amino acids, vitamins, hormones, organic acids, phenolic compounds and polysaccharides.Conclusion: The nitrogen nutrition of grapevines has a clear but complex effect on the chemical composition of wine. Several markers were tentatively identified and their role in wine composition discussed according to the actual knowledge reported in the literature.Significance of the study: This study is an important starting point for selecting the most relevant chemical markers in wine, and for determining whether organoleptic problems are related to nitrogen nutrition deficiency in the vineyard and changes in vineyard management are needed.

Tumbuhan bunga liar yang termasuk dalam tumbuhan bawah merupakan komunitas tumbuhan yang menyusun stratifikasi bawah dekat permukaan tanah. Efek dari batas hutan dapat terlihat dari perubahan gradual mikroklimat serta pola vegetasi dari tepi hutan hingga ke dalam hutan. Dampak dari bertemunya dua kondisi lingkungan yang berbeda tersebut terhadap tumbuhan dan hewan disebut efek tepi (edge effect). Batas hutan berdampak pula terhadap perubahan faktor lingkungan yang meliputi suhu, kelembapan, intensitas cahaya, pH tanah dan tutupan kanopi. Faktor-faktor tersebut diduga berpengaruh terhadap keanekaragaman tumbuhan bunga liar. Hasil penelitian diperoleh jenis tumbuhan bunga liar di Cagar Alam Bantarbolang sebanyak 43 jenis dengan total individu sebanyak 978 individu yang terdiri dari 22 famili. Jenis yang paling banyak ditemukan yaitu Piper caducibrachteum sebanyak 183 individu. Efek tepi berpengaruh terhadap keanekaragaman tumbuhan bunga liar dibuktikan dengan semakin ke dalam hutan jumlah jenis yang didapatkan cenderung semakin sedikit. Jenis tumbuhan bunga liar yang memiliki indeks nilai penting tertinggi adalah Piper betle (66,55%), Piper caducibrachteum (52,44%) dan Ageratum conyzoides (46,17%). Faktor lingkungan yang paling berpengaruh terhadap keanekaragaman tumbuhan bunga liar yaitu intensitas cahaya. Intensitas cahaya semakin ke dalam hutan semakin rendah karena cahaya matahari yang masuk ke dalam hutan terhalang oleh kanopi-kanopi pohon.

Peanut (Arachis hypogea) is a typical plant species of tropical regions that has high economic value. The plantation is widely spread over many areas and the production is being pushed to meet the increasing demand. Peanut breeding program is aimed to improve genetic quality, mainly with resepct of production and thus information on genetic diversity is necessary as a basis for consideration in breeding, management and sustainable utilization. One approach to analyse genetic diversity of peanut is by using molecular markers. Random Amplified Polymorphic DNA (RAPD) is a widely used molecular marker for genetic diversity analysis. Therefore, the aim of this study was to assess genetic diversity of peanut cultivars, i.e. Jerapah, Kancil, and Hypoma 2, based on RAPD markers. The study was conducted in a survey method, in which three individuals of each cultivar were analyzed using PCR-RAPD technique employing twelve primers, i.e. OPA-1, OPA-2, OPA-9, OPA-13, OPB-2, OPB-3, OPB-4, OPB-5, OPB-7, OPB-11, OPB-12 and OPJ-07. Data analysis based on morphological data is also included. Molecular analysis revealed that only 7.55% polymorphic band was obtained, while most of the bands were monomorphic, indicating very low variation among the cultivars. The phenogram that constructed based on literature showed that Kancil was closer to Jerapah cultivar, while RAPD-based dendogram showed that Hypoma 2 was closer to Kancil cultivar.

This paper presents the modeling of the amount of sugar and molasses production in Pabrik Gula Candi Baru Sidoarjo (PGCBS), East Java, by using multivariate mixedlinear models. Estimation of parameters will be done by using maximum likelihood coupled with restricted maximum likelihood methods. The amount of sugar and molasses products which have strong linear correlation, will be set as responses and are supposed to be affected by seven fixed effect variables and four random effect variables. This paper demonstrates that the seven fixed effect variables and only one random effect variable have significant influence on a single response. In the multivariate response modeling, however, all of variables fail to explain the variability of these two responses simultaneously. It is due to the factors matrix has no full rank. As a result, the model response of molasses can be explained by using a model of the amount of sugar obtained.

Poverty is one of the problems that becomes concern in all countries. In Indonesia, one of the provinces that has high poverty rates is Jambi (9.12% in 2015).Result of coordination meeting of all Camat in Jambi Province, reported that the Tabir Barat is the poorest sub-district. The condition is caused mostly by inadequate household infrastructure. Therefore it is necessary for grouping households based on the household infrastructure condition to find the household groups which should be prioritized in the development of poverty alleviation. To describe the poverty variable based on household infrastructure, Bappeda uses 9 indicators, that are residential building status, the widest type of floor, the widest type of wall, the widest type of roof, drinking water source, defecation facility, stool drainage, main lighting and cooking fuel. Because of the folowing reasons: the poverty is an unmeasurable latent variable, and indicators of poverty are categorial variables, the Latent Class Cluster analysis were used in this research as a grouping method. The result shows that there are 5 clusters / latent classeswith their respective characteristics of the household in the Tabir Barat.

On Spacetime Duality and the Astromechanics of a Dual Universe
Authors: Al-Fadhli Mohammed B.
Published: September 2020

Recent astronomical measurements of the fine structure constant revealed it varies slightly through specific directions, which could indicate a directional/anisotropic universe. A curvature in complex spacetime can be interpreted as spatial warping evolution along with its travel through the imaginary time dimension. Complex spacetime worldlines of the universe spatial factor evolution through the imaginary time are utilised to construct a potential cosmic topology. The worldlines of a positively curved universe governed by gravity alone revealed two solutions, which imply that the matter and antimatter could be evolving in opposite directions as distinct universe sides; potentially corroborating the axis of the cosmic microwave background and the directional universe. The model indicates a phase of decelerating spatial expansion during the first 9 Gyr, which is followed by a second phase of accelerating expansion; theoretically resolving the tension in the Hubble parameter measurements, with predicted density at the phase transition of 1.12>1. Additionally, it predicts a final time-reversal phase of spatial contraction leading to a Big Crunch, signalling a cyclic universe. On the spacetime duality, simulations of the spacetime continuum flux along with its predicted worldlines demonstrated the fast-orbital speed of stars due to an external momentum exerted on galaxies via curvature through the imaginary time dimension. These findings indicate the antimatter can exist as a distinct side, which influences the evolution of the universe.

Published: September 2020

Osteopetrosis is a group of rare inheritable disorders of the skeleton characterized by increased bone density. The disease is remarkably heterogeneous in clinical presentation and often misdiagnosed. Therefore, genetic testing and molecular pathogenicity analysis are essential for precise diagnosis and new targets for preventive pharmacotherapy. Mutations in the CLCN7 gene give rise to the complete spectrum of osteopetrosis phenotypes and are responsible for about 75% of cases of autosomal dominant osteopetrosis. In this study, we report the identification of a novel variant in the CLCN7 gene in a patient diagnosed with osteopetrosis and provide evidence for its significance (likely deleterious) based on extensive comparative genomics, protein sequence and structure analysis. A set of automated bioinformatics tools used to predict consequences of this variant identified it as deleterious or pathogenic. Structure analysis revealed that the variant is located at the same “hot spot” as the most common CLCN7 mutations causing osteopetrosis. Deep phylogenetic reconstruction showed that not only Leu614Arg, but any non-aliphatic substitutions in this position are evolutionarily intolerant, further supporting the deleterious nature of the variant. The present study provides further evidence that reconstructing a precise evolutionary history of a gene helps predicting phenotypical consequences of variants of uncertain significance.

Published: September 2020

Usage of antimicrobials in veterinary practices has always been under scrutiny due to the perceived risk of resulting in antimicrobial-resistant pathogens. This creates the necessity for understanding the role of the prescriber group. Hence, we conducted a cross-sectional survey among veterinary practitioners from August to November 2019 in the Chattogram district of Bangladesh, aiming to assess the practitioner’s perceptions regarding antimicrobial prescribing and antimicrobial resistance (AMR) issue. We collected responses from 100 veterinarians engaged in the treatment of the large animal, poultry, and pet animal through a self-administrated questionnaire. Proportions were calculated for categorical variables and the results are presented using visual aids. Our study revealed two key barriers - scarcity of enough information on antimicrobial used, and the lack of training in the proper prescription of antimicrobials. Participants recognized that prescribing too many varieties of antimicrobials and the use of an incomplete course of drugs as two very important causes for the development of antimicrobial resistance. In addition, prescription of inappropriate doses and incentives from pharmaceutical companies were dubbed as important causes. We also found that along with clinical features and types of organisms, the availability of drugs in the local market and the economic conditions of farmers have potential impacts on the antimicrobials prescribing decision of the veterinarians. However, all participants recognized the emerging threats of AMR. Results suggested that capacity building of veterinarians and the maintenance of strong coordination are crucial in ensuring the proper engagement of veterinarians as the front-line fighters for tackling the AMR issue.

The disruption of conventional manufacturing, supply, and distribution channels for medical supplies during the COVID-19 pandemic has caused widespread shortages and catalyzed local efforts to use nontraditional, rapid manufacturing to meet urgent healthcare needs. Here we present a crisis-responsive design framework designed to assist with product development under pandemic conditions. The framework utilizes extensive stakeholder engagement, comprehensive and dynamic needs assessment, local manufacturing, and product testing for the accelerated development of healthcare products. We contrast this framework with traditional medical device manufacturing and discuss relevant regulatory policies. We highlight the applicability of the crisis-responsive framework to a successful local program that designed and supplied face shields for a large US academic hospital. Finally, we make recommendations aimed at improving future resilience to healthcare emergencies. These include continued development of open source designs suitable for rapid manufacturing and changes in regulatory policy that strike a balance between rigidity and uncontrolled innovation.
An Experimental Investigation on the Behavior of Strain Hardening Cement-Based Composites (SHCC) under Impact Compression and Shear Loading

The ductile behavior of strain hardening cement-based composites (SHCC) under direct tensile load makes them promising solutions for applications where high energy dissipation is needed, such as earthquake, impact by a projectile, or blast. However, the superior tensile ductility of SHCC due to multiple cracking does not necessarily entail compressive and shear ductility. As an effort to characterize the behavior of SHCC under impact compressive and shear loading, relevant to the mentioned high-speed loading scenarios, the paper at hand studies the performance of a SHCC and its constituent cement-based matrices using the split-Hopkinson bar method. For compression experiments, cylindrical specimens with a length-to-diameter ratio (l/d) of 1.6 were used. The selected length of the sample led to similar failure modes under the quasi-static and impact loading conditions, which was necessary for a reliable comparison of the obtained compressive strengths. The impact experiments were performed in a split-Hopkinson pressure bar (SHPB) at a strain rate that reached 110 s-1 at the moment of failure. For shear experiments, a special adapter was developed for a split-Hopkinson tension bar (SHTB). The adapter enabled performing impact shear experiments on planar specimens using the tensile wave generated in the SHTB. Results showed a dynamic increase factor (DIF) of 2.3 and 2.0 for compressive and shear strength of SHCC, respectively. As compared to the non-reinforced constituent matrix, the absolute value of the compressive strength was lower for the SHCC. Contrarily, under shear loading, the SHCC yielded the higher shear strength than the non-reinforced matrix.

The determination of crack propagation velocities can provide valuable information for a better understanding of damage processes of concrete. The spatio-temporal analysis of crack patterns developing at a speed of several hundred meters per second is a rather challenging task. In the paper, a photogrammetric procedure for the determination of crack propagation velocities in concrete specimens using high-speed camera image sequences is presented. A cascaded image sequence processing which starts with the computation of displacement vector fields for a dense pattern of points on the specimen’s surface between consecutive time steps of the image sequence chain has been developed. These surface points are triangulated into a mesh, and as representations of cracks, discontinuities in the displacement vector fields are found by a deformation analysis applied to all triangles of the mesh. Connected components of the deformed triangles are computed using region-growing techniques. Then, the crack tips are determined using principal component analysis. The tips are tracked in the image sequence and the velocities between the time stamps of the images are derived. A major advantage of this method as compared to established techniques is in the fact of its allowing for spatio-temporally resolved, full-field measurements rather than point-wise measurements and that information on crack width can be obtained simultaneously. To validate the experimentation, the authors processed image sequences of tests on four compact-tension specimens performed on a split-Hopkinson tension bar. The images were taken by a high-speed camera at a frame rate of 160,000 images per second. By applying to these datasets the image sequence processing procedure as developed, crack propagation velocities of about 800 m/s were determined with a precision in the order of 50 m/s.

This cross-sectional study aimed to assess HIV-related knowledge and attitudes of PHMs, the frontline community health workers in Sri Lanka. Two-hundred and ninety-one PHMs were recruited. PHMs’ knowledge level was good (79.9% of answers were correct) but could be improved. Those more knowledgeable about HIV and with higher education demonstrated a more positive attitude toward PLWH. A more negative attitude, less training and older age were associated with having a stronger intention to engage in extra precautionary behaviors. PHMs need further HIV training to improve their knowledge to better educate the community. By reducing PHMs misperceptions about HIV, they may develop a more positive attitude and thus help reduce the general public’s stigma associated with PLWH.
