Telling all yet revealing nothing: Reality memoir as extension of TV persona
Authors: Englund Lena
Published: December 2024

This article examines personal narratives of reality TV stars and introduces the term reality memoir to describe their unique features and purposes. The reality memoir as discussed here in relation to four texts follows a trajectory different from traditional memoir, being, paradoxically, less about revealing new information than about managing that which is already out there. By doing so, reality memoir effectively becomes an extension of the reality persona. The four memoirs examined are Kris Jenner… and All Things Kardashian (2012) written by Kris Jenner in collaboration with Mark Seal, The Secrets of My Life (2018) by Caitlyn Jenner with Buzz Bissinger, Love Me as I Am (2022) by Garcelle Beauvais together with Nicole E. Smith and Make It Nice (2021) by Dorinda Medley. All four writers are famous for appearing on the reality shows Keeping Up with the Kardashians (2007–21) and the Real Housewives franchise (2006–present). The memoirs indicate that self-promotion remains a central part of the narrative and works to reinforce the image of the persona portrayed on TV. The memoirs also testify to the fact that reality memoir can hardly be defined as a ‘tell-all’, revealing little that is not known to an intended audience familiar with the TV shows.
Motores, caballos y distancia: El transporte como herramienta de trabajo y condición de vida de los asalariados ganaderos de la Provincia de Buenos Aires en el siglo XXI
Authors: Capdevielle Bruno
Published: December 2024

El transporte es central en la vida y el trabajo de los sujetos rurales, en especial de los asalariados de producciones extensivas. Sin embargo, los abordajes sobre la movilidad rural se encuentran focalizados en el estado de los caminos y las condiciones de accesibilidad de la población en general. Sobre esta base, emerge el interrogante sobre la movilidad de los asalariados ganaderos, para quienes la distancia -espacial y temporal- se encuentra presente en el trabajo y la vida cotidiana. El objetivo del artículo es entonces abordar las condiciones en el transporte de los trabajadores ganaderos en el marco de la relación asalariada y los distintos tipos de residencia, haciendo foco en los conflictos y condiciones que se presentan cotidianamente. Para ello nos basaremos en entrevistas que permiten diferenciar tanto la movilidad por trabajo dentro del campo, y entre el campo y el pueblo como el transporte por fuera de las obligaciones laborales.

Published: December 2024

Rainfall modeling and prediction is one of the important things to do. Rainfall has an important relationship and role with various aspects of the environment. One phenomenon that can be associated with rainfall is forest and land fires. Riau is one of the provinces in Indonesia that has a high potential for forest and land fires. This is because Riau has a large area of peatland. One approach that can be used to estimate rainfall is statistical downscaling. The concept of this approach is to form a functional relationship between global and local data. This research uses CMIP6-DCPP output data that will be used to estimate rainfall at 10 observation stations in Riau. The proposed model in this research is Stacking Ensemble with PC Regression and LASSO Regression in the base model and Multiple Linear Regression in the meta model. This research aims to determine the best CMIP6-DCPP model for estimating rainfall in Riau and increasing the accuracy of rainfall estimates using the Stacking Ensemble approach.

Published: December 2024

Generalized Structured Component Analysis (GSCA) is a component-based SEM. One of the developments of GSCA is the GSCA method for multilevel data known as multilevel GSCA. Multilevel data is data that has a nested, grouped, or nested structure. This study aims to apply multilevel GSCA to the data on factors that affect poverty. The data used is on Indonesia's health, education and poverty in 2023.. The result is that all indicators are significant to the latent variables. The structural model shows that the quality of health has a negative and significant effect on poverty, education has a negative and significant effect on poverty, and the quality of health has a positive and significant effect on education. The results of between group show that health quality has a positive and significant effect on education in all regions, health quality has a negative and significant effect on poverty in Bali & Nusa Tenggara, Sulawesi, as well as Maluku and Papua, education has a negative and significant effect on poverty in Sumatra, Java, and Maluku & Papua. The overall goodness of fit value (FIT) is 0.622, meaning the model can explain 62.2% of data variation.
Case study on recent trends in export rejections of spices from India: reasons, responses and regulatory challenges
Authors: Thomas Lijo , Sajesh V K , Sanil P C
Published: December 2024

Spices, integral to culinary traditions worldwide, significantly contribute to global trade and India's agricultural economy. India, the leading producer and exporter of spices, accounts for 7.7% of country’s agricultural export earnings and exports to over 185 countries. Despite impressive growth in production and exports, export rejections remain a critical challenge, with over 200 consignments rejected annually due to factors such as pesticide residues, microbial contamination and poor labelling. These rejections, which vary by export destinations, compromise India’s reputation and economic interests, particularly affecting smallholder farmers who dominate spice production. As a global supplier of spices, India's food safety and spice quality have global ramifications.
This study uses data from the United Nations Industrial Development Organization (UNIDO) Knowledge Hub (2010-2022) to analyses export rejections of Indian spices under HS code 09. It focuses on trends, underlying causes and mitigation strategies. Although aggregate rejection rates have declined by 53 % over the past decade, the number of export rejections is still significant. Mitigation strategies, including adoption of Good Agricultural Practices (GAP), Hazard Analysis and Critical Control Points (HACCP) protocols, traceability systems and capacity building, are crucial. Addressing export rejections requires an integrated approach involving all stakeholders in the spice value chain. Strategic investments in technology, training and research, along with proactive engagement with trade partners, are essential for sustaining India’s dominance in the global spice trade. Further research is necessary to evaluate compliance costs and their implications for both producers and consumers, paving the way for more sustainable trade practices.

Published: December 2024

Gastric cancer is the fifth most notable health concern globally. In recent years, molecular docking, a computational technique, has emerged as tool in drug discovery. The present investigation aimed to identify the major bioactive compounds in the wild-type curry leaves found in the Shevaroy Hills and the local Senkambu variant from Karamadai. Virtual screening of 40 ligands from Curry leaves of wild type and Senkambu type was identified through GC-MS profiling. These compounds were targeted against HER2 Kinase domain which is a potential receptor for Gastric cancer. Information regarding the binding site residues for the receptor was predicted using CASTp server. Molecular docking was performed for HER2 kinase domain with the predicted compounds through GC-MS profiling. The top 3 hits reported with least binding affinity for the target protein were considered for further interaction analysis using Biovia Discovery studio visualizer. Upon analyzing the interacted compounds, the Piperine from Wild type curry leaves was found to have good interaction with HER2 Kinase domain by forming two hydrogen bonds and binding score of -8.3 k cal/mol. The current study might guide the designing of analogues of piperine in the evolution of effective broad spectrum drug development in cancer therapy.

Black pepper, known as the "King of Spices" and "Black gold," is a valuable spice native to India, commonly cultivated in tropical regions. However, it is prone to fungal growth and mycotoxin contamination, particularly during storage when moisture levels rise. Therefore a survey was conducted during July to December 2023, for identifying the mycoflora associated with black pepper in storage. Stored samples of the contaminated whole black pepper collected from pepper growers in 3 locations each from Thiruvananthapuram, Kozhikode, Idukki and Wayanad districts (Agro ecological units (AEU) 14, 15, 16 and 20) of Kerala, India. Twelve samples collected were examined to record the symptoms, then isolate the mycoflora associated with the samples and the prevalent contaminants present in it were characterized. The average moisture content of the samples was determined and found below 10 per cent for all the black pepper samples. Sixty one isolates of different fungi were isolated from the samples collected from different locations in Kerala. 14 isolates from Thiruvananthapuram, 16 from Kozhikode, 16 from Wayanad and 15 from Idukki were isolated from mouldy black pepper berries. Cultural and morphological studies of the 61 isolates were carried out and the isolates includes Aspergillus sp., Penicillium sp., Syncephalastrum sp., Mucor sp., Colletotrichum sp., Helminthosporium sp. Among the contaminants, one of the isolates of Aspergillus sp. observed from most of the samples collected was subjected to cultural, morphological and molecular characterization. Major contaminant associated with black pepper at storage was identified as Aspergillus flavus.

Published: December 2024

The present study aimed to standardize soilless media mixtures for papaya propagation, focusing on stability, sustainability and environmental impact. A trial was conducted in the winter and summer seasons during 2023-2024 at TNAU, Coimbatore, to evaluate the properties of cocopeat mixtures and optimize the cocopeat media mixture for papaya seedling production. The trial employed a factorial randomized complete block design with two factors [cocopeat media mixture (Factor-T) and papaya varieties (CO7 and TNAU Papaya CO8, as factor-V] and with four replicates. Each treatment contains different proportions of cocopeat, inorganic fertilizers, bio-inoculants, biofertilizers and oil cakes. Commercially available cocopeat and potting mixture were used as absolute control and control, respectively. The findings showed that T2 (TNAU Mixture 2) consist of cocopeat (96.86%) + inorganic mixture (0.34%) + bioinoculant mixture (0.70%) + biofertilizer mixture (0.42%) + oil cakes mixture (0.42%) recorded increased seed vigour (96.86%), seedling survival (96.17%), seedling height (46.07 cm), leaf area/plant (28.50 cm²), leaf chlorophyll (26.05 SPAD units) and total nutrient (N-1.89%, P-0.89%, K-3.47%). The treatment T4 (commercially available cocopeat alone) had the highest germination (97.90%) and was on par with T2. Among the variety, V2 outperformed V1. In the treatment (T) and variety (V) interaction, the T2×V2 combination promoted significant seedling growth at the nursery. Cocopeat media mixtures showed good physical properties, like bulk density(g/cc), particle density (g/cc), porosity (%) and water holding capacity (%), promoting better seedling growth. The trial revealed that the treatment T2 is recommended as the best alternative soilless medium for papaya propagation.
Perception and adoption of drip irrigation technology among beneficiaries of the Tamil Nadu Irrigated Agriculture Modernization Project: A Structural Equation Modelling approach
Authors: D Abila Doss , Asokhan M , Balasubramaniam P , Kumaresan P
Published: December 2024

The article examines the beneficiaries’ perceptions of Drip Irrigation Adoption under the Tamil Nadu Irrigated Agriculture Modernization Project using a quantitative research approach and Structural Equation Modelling (SEM). A survey was conducted with 559 respondents from different districts of Tamil Nadu using the Technology Acceptance Model (TAM). Perceived Usefulness (PU), Perceived Ease of Use (PEU), Attitude Toward Use (ATU) and Behavioural Intension (BI) were some of the key constructs in the study. The study utilized a structured questionnaire for data collection, which was then analyzed using percentage analysis and SEM to explore the relationships among the constructs. The results showed that the respondents were predominately older, more experienced farmers with small to marginal landholdings. Educational levels among the respondents were diverse but skewed toward middle and secondary schooling, with (47.39%) having received this level of education. Incomes were predominantly in the lower-middle-class range, with respondents showing moderate interest in scientific practices and a high degree of openness to innovation. The study established that Perceived Usefulness and Perceived Ease of Use were crucial factors influencing farmers' attitudes toward drip irrigation, affecting their behavioural intention to adopt the technology. This study concludes that perceived benefits and ease of use are critical drivers in encouraging the adoption of water-saving technologies such as drip irrigation among farmers. Future research could include longitudinal studies on whether drip irrigation is eventually adopted and impacts farm productivity and water conservation. It may be possible to extend the model to include external variables, such as social influence, economic incentives and policy support, to better understand adoption dynamics.
Survey of Geriatric Competencies and Curricular Models in Entry-Level DPT Programs in the United States
Authors: Mierzwicki Justin T. , Blood Karen M.
Published: December 2024

Background and Purpose:

Nearly 2 decades have elapsed since the last national survey examining entry-level PT geriatric content. Furthermore, no survey has been completed investigating the extent to which the “Essential Competencies in the Care of Older Adults at the Completion of Entry-level Physical Therapist Professional Program of Study” were incorporated into DPT programs. The purpose of this study is to identify the extent to which DPT programs include geriatric topics and the Essential Competencies within curricula and determine geriatric content requiring proficiency for entry-level practice.

Methods:

A survey was developed in Qualtrics™ and distributed via email 4 times over 2 months in 2023 to DPT program chairs and APTA social media platforms. The survey contained sections on geriatric curriculum models, environment of content coverage, incorporation of Essential Competencies, and skills requiring entry-level proficiency. Data analysis was completed using descriptive statistics.

Results and Discussion:

Responses were received from 134/276 programs. Seventy-nine and nine tenths percent of responding programs have a dedicated geriatric course, 93.4% of which require 1 geriatric course, with a mean of 2.6 credits (SD 1.02). In programs without dedicated geriatric courses, a mean of 2.7 credit hours (SD 2.88) of geriatric content was reported. Eighty-nine percent of programs cover age-related changes to major body systems and balance and fall screening, with <60% addressing interventions for cognition and social isolation. Of the surveyed Essential Competencies, 80.4% were incorporated into >70% of programs. A total of 31.6% of the tests and measures were taught, 15.8% were practiced, and 10.5% were identified by >70% of programs as requiring proficiency for entry-level practice.

Conclusions:

There is variation in geriatric content incorporated into entry-level DPT programs and moderately robust uptake of Essential Competencies. Entry-level education may not meet APTA-Geriatrics Best Practice guidelines with relatively few tests, measures, and interventions recommended with consensus to be proficient prior to entry-level practice. Improved knowledge translation and curricular guidance may help reduce practice variation and enhance entry-level education in geriatric physical therapy.
ANALISES DE GRÃOS DE AMIDO E FITÓLITOS NAS TERRAS ALTAS DO SUL DO BRASIL: REPENSANDO A ECONOMIA E MOBILIDADE DOS GRUPOS PROTO-JÊ MERIDIONAIS

Published: December 2024

Resumo: Este artigo apresenta os resultados das analises de grãos de amido e de fitólito de 14 fragmentos cerâmicos recuperados em duas estruturas de cocção domésticas de uma casa semissubterânea dos  proto-Jê Meridionais no sítio Bonin (Urubici, Santa Catarina, sul do Brasil) que datam de 1350 e 1340 cal . yr. AD. A inédita aplicação de técnicas para estudos de plantas microfósseis nesta região revelou, pela primeira vez, o consumo da mandioca (Manihot esculenta), feijão (Phaseolus sp.), e, possivelmente, inhame (Dioscorea cf. sp.) além de milho (Zea mays) e abóbora (Cucurbita sp.). Estes resultados mostram que os proto-Jê meriodionais tiveram uma economia de subsistência baseada em uma ampla gama de alimentos de origem vegetal e praticavam a produção de alimentos mais de um século antes da conquista européia. Ao contrário do que os modelos tradicionais da mobilidade proto-Jê meriodionais, nossos dados sugerem que a produção de alimentos pode ter permitido que estas populações permanecessem o ano interio no planalto sul brasileiro, sem a necessidade de realizar movimentos sazonais para a escarpa e para a costa para adquirir a maior parte dos recursos alimentares. Nossos dados complementam evidências arqueológicas que paontam para o sedentarismo e a emergênica da complexidade social entre grupos proto-Jê do sul, incluindo a construção de grandes e bem planejadas aldeias de casas semissubterrâneas, e a criação de uma paisagem altamente estruturada no entorno de estruturas funerárias.Abstract: This article presents the results of starch grain and phytolith residue analyses from 14 ceramic fragments recovered in two domestic cooking structures from a southern proto-Jê pit house at the Bonin site (Urubici, Santa Catarina state, southern Brazil) dating to 1280 and 1420 cal. yr. AD and 1280 and 1400 cal. yr. AD. The novel application of plant microfossil techniques in this region revealed, for the first time, the consumption of manioc (Manihot esculenta), beans (Phaseolus sp.), and possibly yams (cf. Dioscorea sp.) in addition to maize (Zea mays) and squash (Cucurbita sp.). These findings show that southern proto-Jê people had a subsistence economy based on a broad range of plant foods and practiced food production more than one century before European Conquest. Contrary to traditional models of southern proto-Jê mobility, our data suggest that food production may have allowed populations to settle in the southern Brazilian highland plateau year round without the need to carry out seasonal movements to escarpment and coast to acquire the most part of food resources. Our data complement archaeological evidence for sedentism and social complexity among southern proto-Jê groups, including the construction of large, well-planned pit-house villages, and the creation of a highly structured landscape revolving around funerary structures.

Excitatory synapses and the actin-rich dendritic spines on which they reside are indispensable for information processing and storage in the brain. In the adult hippocampus, excitatory synapses must balance plasticity and stability to support learning and memory. However, the mechanisms governing this balance remain poorly understood. Tiam1 is an actin cytoskeleton regulator prominently expressed in the dentate gyrus (DG) throughout life. Previously, we showed that Tiam1 promotes dentate granule cell synapse and spine stabilization during development, but its role in the adult hippocampus remains unclear. Here, we deleted Tiam1 from adult forebrain excitatory neurons (Tiam1fKO) and assessed the effects on hippocampal-dependent behaviors. Adult male and femaleTiam1fKOmice displayed enhanced contextual fear memory, fear extinction, and spatial discrimination. Investigation into underlying mechanisms revealed that dentate granule cells fromTiam1fKObrain slices exhibited augmented synaptic plasticity and N-methyl-D-aspartate–type glutamate receptor (NMDAR) function. Additionally, Tiam1 loss in primary hippocampal neurons blocked agonist-induced NMDAR internalization, reduced filamentous actin levels, and promoted activity-dependent spine remodeling. Notably, strong NMDAR activation in wild-type hippocampal neurons triggered Tiam1 loss from spines. Our results suggest that Tiam1 normally constrains hippocampal-dependent learning and memory in the adult brain by restricting NMDAR-mediated synaptic plasticity in the DG. We propose that Tiam1 achieves this by limiting NMDAR availability at synaptic membranes and stabilizing spine actin cytoskeleton and that these constraints can be alleviated by activity-dependent degradation of Tiam1. These findings reveal a previously unknown mechanism restricting hippocampal synaptic plasticity and highlight Tiam1 as a therapeutic target for enhancing cognitive function.

Published: December 2024

We describe a chamber system to perform imaging, electrophysiology, and optogenetic stimulation in awake and anesthetized marmosets. We developed this low-profile chamber design to be able to access the underlying tissue when needed or to leave it sealed for long periods. Such accessibility is useful to maintain chamber clarity as well as perform viral or drug injections at different time points. The chamber is flexible as either optical or electrophysiological recording can be performed in the same chamber by exchanging chamber inserts. The design provides an easy approach to day-to-day stable neural recordings that was developed for marmosets and can be extended to other species.

Authors: Mingyue Duan , Chiang Wong Shaw
Published: December 2024

With society rapidly evolving alongside digital technology and pan-entertainment, there is a notable decline in appreciation and understanding of Sichuan Opera among China’s Generation Z (Gen Z). This study aims to develop and evaluate the potential of innovative illustration as a tool to promote the cultural content and emotional elements of Sichuan Opera arts among China’s Gen Z. This qualitative participatory action-based research was guided by an iterative cycle of planning, acting, observing, and reflecting. This study comprised three stages. In the pre-design stage, nine (9) experts were selected through purposive and snowball sampling to explore their views on the cultural content and emotional elements of Sichuan Opera arts. Thematic analysis with NVivo 12 yielded six (6) cultural content, i.e., a form of expression, performance occasions, performance techniques and dance movements, performance repertoire, character roles, costumes and make-up. The emotional elements encompassed the emotions expressed within Sichuan Opera itself (such as the characters’ roles and personalities and traditional morals and philosophies), as well as people’s emotions towards Sichuan Opera (including their yearning for its sentiment and their awareness of the need to protect traditional culture). These content and elements were visually expressed through three (3) innovative illustrations in the design stage. In the post-design stage, a sample of 25 China’s Gen Z from Chengdu was conveniently selected to evaluate the effectiveness of the illustrations. The use of innovative illustrations as a medium to promote the dissemination of the art of Sichuan Opera among China’s Gen Z has successfully merged traditional culture with modern aesthetics.

Under the background of modern scientific and technological art practice, artworks with contemporary characteristics are often created based on conventional culture and art. The important module of this study is Xu Shi, also known as the White Space technique, which is a critical component of composition and aesthetics in Chinese Ink Painting, derived from an aesthetic system in the long tradition of Chinese culture. Despite the existence of numerous scholarly investigations pertaining to the Xu Shi concept within the realm of traditional Chinese Ink Painting, there remains a significant deficiency in research focused on the practical application of Xu Shi principles in the domain of electronic art. Therefore, this study identifies the importance of Xu Shi whereas the main visual criteria for the formation of conventional Chinese Ink Painting and in what manner interpreted the form of electronic art. This research conducted practical applications to determine the viability of using Xu Shi technique to convey electronic art, which presents this adaptation as possible. The study method included formal visual analysis, mathematical calculations, and practice-led research. Through this merger, it is possible to create electronic art that provides a fresh perspective and significance of Chinese ink painting in a new background beyond the traditional context.

In the present study, two series of solid solvent-free polymeric membranes based on diblock copolymers MePEO-b-PAAm (DBC) and triblock copolymers PAAm-b-PEO-b-PAAm (TBC), comprising chemically complementary poly(ethylene oxide) and poly(acryl amide) have been prepared by using casting technique. The dielectric properties of the prepared membranes in the frequency range of 102–105 Hz at room temperature as a function of water content and the length of the PEO block, as well as the peculiarities of water absorption processes under variable humidity, were investigated. It was found out that increasing the length of the PEO block led to an increase in the ionic conductivity of the obtained membranes. Such results confirmed the significant contribution of oxyethylene chains in ensuring the conductivity of lithium and solar cell batteries. The increase of relative humidity from 33% to 98% resulted in the increase of conductivity of DBC and TBC membranes up to 2.77·10-6–8.48·10-4 S·cm-1. According to the obtained results, block copolymers containing the interacting polymer components can be considered as potential solid polymer matrices for proton exchange membranes and they open the way for their application in fuel cells.

The aim of the work is to modify existing paints and varnishes based on alkyd varnish (PF-170) and to create new film formers using functionalized oligomers to improve the properties of materials during their operation. In order to obtain new polymer materials, a method of synthesizing a modifier - an oligomeric amino urethane acrylate compound was developed, the synthesis of which was carried out in several stages with the preparation of aminourethane carbonate of soybean oil with the formation of urethane groups by the non-isocyanate method and the subsequent addition of a methacrylate oligomer. The reaction was monitored by the method of IR spectroscopy by the decrease in the intensity of the absorption band of the cyclocarbonate group (1803 cm–1), the formation of the absorption band of the urethane group (1698 cm-1), the redistribution of hydroxyl and amine groups, and was further evaluated by the disappearance of the absorption band of epoxy groups
(909 cm–1) and the detection of the C=C absorption band (1638 cm–1). By adding the synthesized oligomer to an alkyd varnish, a new film-forming system was obtained for the formation of coatings by oxidative polymerization in air. The optimal concentration of the modifier is (5–7) % of its content. These materials are characterized by high viability, homogeneity, and make it possible to obtain transparent high-quality coatings with high physical and mechanical characteristics. The developed composite materials based on modified varnish can be recommended for practical use in various technologies for the production of coatings, alkyd varnishes, and paints, which are characterized by an appropriate set of physical and mechanical properties.

The composition of thermoplastic starch (TPS) was prepared using glycerol as a plasticizer, lactic acid and its binary mixture with stearic acid. A number of component concentrations and thermo-mechanical technological parameters were varied during starch processing and formation of film-forming compositions. Physical-mechanical tests of TPS film samples were carried out, and the strength and elasticity properties were determined depending on the concentration of plasticizer and structure-forming additives. The effect of UV irradiation on the degradability of TPS compositions and TPS film samples with synthetic polymer - polyethylene was studied. The optimal composition, loss of strength and elasticity in the range of 80–100% after 90 days of aging in a climate chamber were determined. Mass spectrometric study of TPS films before and after UV irradiation confirmed the influence of structure-forming additives of stearic and lactic acids on the degradability of TPS compositions. The obtained results indicate the possibility of forming plastic materials with the ability of rapid degradation under environmental conditions.

The results of this study indicate that legal protection for concurrent creditors has been achieved, which is indicated by the consideration of the judge's decision in granting the application for cancellation of concurrent creditor peace so that Decision Number 25/Pdt.Sus-Cancellation of Peace/2022/PN Niaga.Jkt.Pst is officially canceled and the debtor is bankrupt. The panel of judges in deciding the case certainly considers the rights of concurrent creditors contained in Law Number 37 of 2004 concerning Bankruptcy and PKPU so that by achieving legal certainty, it simultaneously guarantees that Law Number 37 of 2004 also provides legal protection to concurrent creditors
 
Penelitian ini menggunakan metode penelitian normatif dengan jenis penelitian kualitatif karena berfokus pada peraturan perundang-undangan. Penelitian ini menggunakan pendekatan perundang-undangan (statue approach) dan pendekatan kasus (case approach). Hasil penelitian ini menunjukan bahwa perlindungan hukum bagi kreditor konkuren telah tercapai yang ditandai dengan pertimbangan putusan hakim dalam mengabulkan permohonan pembatalan perdamaian kreditor konkuren sehingga Putusan Nomor 25/Pdt.Sus-Pembatalan Perdamaian/2022/PN Niaga.Jkt.Pst resmi dibatalkan dan debitor pailit. Majelis hakim dalam memutuskan perkara tentunya mempertimbangkan hak-hak kreditor konkuren yang terdapat pada Undang-Undang Nomor 37 Tahun 2004 tentang Kepailitan dan PKPU sehingga dengan tercapainya kepastian hukum tersebut maka sekaligus menjamin bahwa Undang-Undang Nomor 37 Tahun 2004 juga memberikan perlindungan hukum terhadap kreditor konkuren.

Типи лісу, встановлені проф. З.Ю. Герушинським для Українських Карпат, лісовпорядними експедиціями використовуються і на сьогодні під час базового лісовпорядкування. Наведено особливості розподілу площ ялинових деревостанів за переважаючими типами лісу і класами бонітету в межах лісового фонду на території Закарпатської, Івано-Франківської, Львівської і Чернівецької областей. Серед типів лісу за площею домінує волога буково-ялицева сусмеречина. Встановлені середні значення класів бонітету для переважаючих типів лісу може бути використано під час аналізу ефективності лісовирощування у регіоні досліджень. Результати групування площ ялинових деревостанів за експозицією схилу і типами лісу в межах чотирьох областей підтвердили приуроченість окремих типів лісу до експозиції схилу, що вказує на локальний характер такої залежності в межах окремих областей і не поширюється на всю територію Українських Карпат. Наведено значення середньої зміни запасів ялинових деревостанів з відносною повнотою 0,7 з їх розподілом за переважаючими типами лісу і класами бонітету в межах лісового фонду досліджуваного регіону. Найвищі значення зміни запасу характерні для деревостанів вологої буково-ялицевої смеречини Id класу бонітету і можуть становити від 10,6 до 12,2 м3∙га-1 за рік. Вища інтенсивність нагромадження запасів деревини в умовах вологих сугрудів властива ялинникам Львівської та Івано-Франківської областей, а в умовах вологих грудів – Закарпатської області. Фактична продуктивність ялинових насаджень різних груп віку у переважаючих типах лісу така: середній запас стиглих ялинових деревостанів у грудових типах лісорослинних умов становить близько 500, сугрудових – 400-450, суборових – 300-400 м3∙га-1. Запаси стовбурової деревини еталонних високоповнотних деревостанів у межах типів лісу та адміністративних областей становлять 800-1000 м3∙га-1.

Представлено результати трирічних досліджень укорінення живців і висоти живцевих однорічних саджанців тополі культиварів 'Dorskamp', 'І-45/51', 'Robusta' і тополі Торопогрицького на чорноземах Правобережного Лісостепу України. Однорічні здерев’янілі живці завдовжки 20, 25 і 30 см висаджували восени (листопад) і рано навесні (початок квітня). За осіннього садіння укоріненість живців тополі різних сортів у 2019 р. становила: у 'Dorskamp' – від 77,4 до 96,7%, у 'І- 45/51' – від 71,0 до 93,4%, у 'Robusta' – від 87,7 до 96,7% та у тополі Торопогрицького – від 61,7 до 88,3%. Подібні результати було також отримано і в 2020 році. У 2021 р. найвищу укоріненість у сортів 'Dorskamp' і Торопогрицького мали живці завдовжки 30 см – 63,3 і 81,7% відповідно. У сортів 'І- 45/51' та 'Robusta' найкраще вкоренилися живці завдовжки 20 см – 65,0 і 73,3% відповідно. За весняного садіння укоріненість різних сортів у 2019 р. становила: у 'Dorskamp' – від 77,4 до 90,3%, у 'І-45/51' – від 64,5 до 93,5%, у 'Robusta' – від 67,7 до 83,9% і в тополі Торопогрицького – від 58,1 до 83,9%. У 2020 р., внаслідок сухої і холодної погоди на початку вегетації, укоріненість живців досліджуваних сортів була низькою (у 'Dorskamp' – від 41,7 до 85,3%, у 'Robusta' – від 12,5 до 20,0%, у 'І-45/51' – від 20,0 до 28,3% і у Торопогрицького – від 35,0 до 48,3%). За осіннього садіння найбільшу висоту мали живцеві саджанці тополі Торопогрицького (у 2019 р. –196,9±6,18 см, у 2020 р. – 183,9±2,82 см, а у 2021 р. – 217,6±3,70 см). За весняного садіння живців сорту 'Dorskamp' отримано такі результати: у 2019 р. – 204,6 см, у 2020 р. – 176,4 см, а у 2021-му – 228,6 см. Рослини сортів 'І-45/51' і 'Robusta' за весняного садіння мали середню висоту відповідно 122,4-128,3 см і 131,9-149,1 см.

Наведено результати системно-структурного аналізу флори ялицево-букових лісів низькогір’я Покутських Карпат. Здійснено таксацію деревостану, інвентаризацію флори і мікобіоти, фітосоціологічні описи рослинності та її синтаксономічний аналіз. Встановлено, що сукупно у складі рослинного вкриття ялицево-букових лісів за 11-річний період спостережень було виявлено 223 види вищих судинних рослин, що належать до 168 родів, 65 родин, 46 порядків, 6 класів, 5 відділів та 31 вид мохоподібних із 30 родів, 24 родин, 10 порядків, 5 класів, 2 відділів. Ценофлора ялицево-букових лісів укладена за схемою, характерною для листяних лісів назагал. Серед життєвих форм рослин в ялицево-букових лісах провідна роль належить полікарпічним травам, участь яких сягає 74,0%. З-поміж багаторічних трав у зімкнених деревостанах домінують довгокореневищні види (22,7%). За зміни фітосередовища ялицево-букових лісів у процесі вибіркових рубок серед трав’янистих рослин з’являються стрижнекореневі (19,3%) і пучкуватокореневі (11,3%), роль яких у природних лісах є незначною. Серед рослин переважають вегетативно-рухомі види (40,0%) з життєвою стратегією стрес-толерант (S) (55%). В ялицево-букових лісах встановлено значну частку гемікриптофітів (46,0%) та криптофітів (30,0%). Спостереження за змінами, які відбувалися у видовому складі фітобіоти у процесі самозаростання пройдених рубками ділянок, базувалися на фіксації кількісних показників видів з п’яти тестових груп: характерних для деревостанів ялиці білої і бука лісового, для зрубів, груп рудеральних бур'янів і лучних видів. Встановлено, що види різних тест-груп демонструють три типи динаміки кількісних показників. Спадаючий тип динаміки відзначено у рудеральних і лучних видів, зростаючий тип властивий для видів на зрубах та узліссях, проміжний тип виявлено у всіх лісових видів.
ДЕСТРУКЦІЯ ТКАНИН ДЕЯКИХ ЯГІД ТА ФРУКТІВ ПРИ НАГРІВАННІ

Ягоди та фрукти є важливим елементом у здоровому харчуванні завдяки високому вмісту біологічно активних речовин. В той же час вони містять у своєму складі до 90% води. Це призводить до того, що в процесі зберігання вони можуть швидко псуватись та втрачати свою природню цінність. Тому для мінімізації втрат урожаю плодово-ягідну сировину піддають термічній переробці. З метою оптимізації теплової обробки сировини методами термічного аналізу були проведенні дослідження процесів деструкції, що відбуваються при нагріванні матеріалу. Проаналізовано 17 видів ягід та фруктів, широко представлених в літній сезон на ринку України. Дослідження подрібнених зразків з їстівної частини свіжих плодів проведено в дериватографі при нагріванні з постійною швидкістю до 250 °С. Результати термічного аналізу свідчать, що першим етапом деструкції є дегідратація матеріалу, яка супроводжується поглинанням теплоти. В результаті аналізу отриманих даних були визначені вологість, характерні температури, швидкість та умовний тепловий ефект зневоднення зразків. Встановлено, що кінетика процесу дегідратації та величина умовного теплового ефекту залежить від вмісту вільної та зв’язаної води в продукті і їх співвідношення. Показано, що вміст зв’язаної води визначається хімічним складом, в якому вуглеводи відіграють головну роль. Встановлено, що після повного видалення води відбувається деструкція органічних речовин, яка протікає з поступовою втратою маси зразків та з наростаючим виділенням теплоти. Виявлено, що досліджені фрукти та ягоди можна умовно поділити на дві групи за характером розкладання термолабільних складових органічних речовин. Визначено термічну стабільність досліджених ягід та фруктів, як граничну температуру, після досягнення якої спостерігається розкладання органічних речовин в продукті. Дана температура є одним з основних режимних параметрів термічної обробки плодово-ягідної сировини, що забезпечує високу якість продуктів переробки. Припущено, що термічна стабільність залежить від вмісту моно- та дисахаридів, що входять до складу.

У світі збільшується попит на функціональне харчування, яке може забезпечувати організм людини макро- та мікронуктієнтами, зменшувати ризик хронічних захворювань, покращувати фізичний стан і психічне благополуччя. Функціональне харчування відіграє важливу роль у підтримці здорового способу життя та зниженні факторів ризику різних захворювань. До функціональних продуктів відносять ті, які містять один або кілька біологічно активних харчових інгредієнтів. У харчовій, косметичній та фармацевтичній промисловості значний потенціал для прогресу продемонстрували каротиноїди, завдяки своїй багатій поживній цінності та функціональними властивостями. Каротиноїди це природні органічні пігменти, що виробляються мікроорганізмами та рослинами. Сьогодні розпізнано близько 600 каротиноїдів. Їх поділяють на два класи: ксантофіли та каротини. Каротиноїди в основному містяться у фруктах, ягодах, овочах, мікроорганізмах і деяких морських організмах. Хурма (Diospyros Kaki L.)  – це солодкий, злегка терпкий фрукт, який є джерелом бета-каротину, вітамінів А і Е, аскорбінової кислоти, багата вуглеводами, дубильними речовинами і фенольними сполуками, є хорошим джерелом клітковини, а також має потужну антиоксидантну дію. Хурма найбільш поширена в країнах Східної Азії. Хурма відноситься до сезонних продуктів, та має обмежені терміни зберігання, для їх збільшення можна використовувати сушіння. Більш розповсюдженими методами сушіння є конвекція, сублімація, сонячне та інфрачервоне. З цих методів конвективне сушіння дає якісний матеріал з меншими енерговитратами. Але при цьому в світі розповсюджується комбіноване сушіння. Тому метою роботи є переробка плодів хурми сушінням та визначення впливу різних режимів. Дослідження кінетики сушіння показало, що найбільш доцільними режимами є ступеневий та комбіновані режими сушіння, які інтенсифікують процес у 1,92 та 1,63 рази порівняно з 65 ºС.
