Palaeobiogeography, palaeoecology, and sequence stratigraphy of the Upper Jurassic carbonate succession of the Lar Formation, central Alborz Zone, Iran
Authors: Saleh Zahra , Reháková Daniela
Published: December 2023

Foraminifera, ammonites, and calcareous dinoflagellates were used for stratigraphy and, together with microfacies, for the assessment of the palaeoenvironmental conditions of the Upper Jurassic deposits in the central Alborz Zone of northern Iran. The Lar Formation (Lar Fm.) in the Polur section is of latest Oxfordian to early Kimmeridgian age. The ammonite Subnebrodites planula and the calcareous dinoflagellate Colomisphaera nagyi have been introduced as new biomarkers of the lower Kimmeridgian in the central Neo-Tethys. The distribution of calcareous dinoflagellates reflects possible dispersal routes along a narrow seaway between the western Neo-Tethys and the Alborz Zone in the central Neo-Tethys. The Terebella-Crescentiella associations of the Lar Fm. represent a low-energy setting under dysoxic conditions in the Central Neo-Tethys Ocean. The benthic foraminiferal assemblages in this formation show a high dominance of infaunal taxa and r-selected strategists. This assemblage is reminiscent of eutrophic conditions and low oxygen levels in the lower part of the Lar Fm. Good preservation of the hexactinellid sponges in the upper part of the Lar Fm. also indicates an oxygen-minimum zone. Three third-order depositional sequences can be distinguished in the study area based on six microfacies. Depositional sequence 1 (DS1) is composed mainly of argillaceous limestone and medium- to thick-bedded limestone, corresponding to an outer ramp-to-middle ramp environment. Depositional sequence 2 (DS2) comprises breccia limestone and thick-bedded limestone facies in its lower part and thin-bedded limestone to massive limestone in its upper part. The breccia limestone facies may be associated with subaerial exposure and reworking of previously deposited sediment during a relative sea level fall. The thin-bedded limestone to massive limestone of DS2 consists mainly of bioclastic mudstone to wackestone (outer ramp). These represent an deep-water outer homoclinal ramp facies. Depositional sequence 3 (DS3) consists mainly of massive limestone to thick-bedded limestone with a bioclastic peloidal microbial Crescentiella packstone (middle ramp). The relative stratigraphic positions of DSs1–3 and sequence boundaries in the uppermost Oxfordian to lower Kimmeridgian of the Polur area show a fair match to the upper Oxfordian to lower Kimmeridgian sequences (JOx7, JOx8, JKi1 and JKi2) on the global sea level curve.
Record of Late Neogene seismites in turbidite deposits of the Tafna Basin (NW Algeria)

Published: December 2023

The wide variety of soft-sediment deformation structures (SSDS) developed within deposits of the same age may hinder the interpretation of their origin. Some types of SSDS may appear similar though have different trigger mechanisms, while others may result from a specific mechanism. Furthermore, the development of particular SSDS may be influenced by several synchronous or semi-synchronous factors. This study deals with the recognition of SSDS trigger mechanisms with respect to lithological and deformational features of the deposits concerned. Turbidite deposits of late Neogene age in the Hadjret El Gat area (Tafna Basin) contain different types of SSDS associated with (1) slope processes (e.g., slump folds) and induced overburden pressure, coupled with broken beds and overloading structures, and (2) liquefaction and fluidisation phenomena, leading to the development of load structures, ball-and-pillow structures, water-escape structures and syndepositional faults. These two mechanisms of SSDS formation in the study area are thought to result from seismically-induced triggers. Recognition of a vertically-repeated, sandwich-like arrangement of deformed and undeformed layers along with the SSDS features ("trapped" within beds) suggests that these internally-deformed beds are seismites, the first recognized in the Tafna Basin of NW Algeria. Large earthquakes may trigger seismic waves energetic enough to deform strata and induce the development of SSDS. This hypothesis is supported here by tectonic evidence, given deposition of the Tafna Basin strata in the convergence zone between Africa and Eurasia, active since the late Neogene.

Thrombectomy procedures following intra-aneurysmatic lesions are extremely rare, and few cases have been reported. This article describes a microsurgical intra-aneurysmatic thrombectomy (MIaT) for a distal anterior cerebral artery (DACA) aneurysm. We present the case of a 48-year-old female that was admitted to the emergency room, showing neurologic deterioration with focal deficits. A computed tomography angiography (CTA) scan revealed an aneurysm located in the distal segment of the left anterior cerebral artery. During the surgical procedure, after clipping, a wellformed clot was visualized through the aneurysm’s wall obstructing the left DACA flow. We proceeded to open the aneurysm’s dome to remove the thrombus and clip the aneurysm neck, re-establishing the flow of the left DACA.Intra-aneurysmatic thrombosis can occur as a complication during clipping, obstructing the distal flow of vital arteries and causing fatal results in the patient’s postoperative status. MIaT is a good technique for restoring the flow of the affected vessel and allows a secure aneurysm clipping after thrombus removal.
IS200/IS605 Family-Associated TnpB Increases Transposon Activity and Retention
Authors: Kaur Davneet , Kuhlman Thomas E.
Published: December 2023

The IS200/IS605 family of insertion sequences are abundant mobile elements associated with one of the most numerous genes found in nature,
tnpB
1–3
. Previous studies suggest that TnpB protein may be an evolutionary precursor to CRISPR Cas enzymes, and TnpB has received renewed interest having itself been shown to function as a Cas-like RNA-guided DNA endonuclease
3,4
. However, interpretation of the fundamental role of TnpB in transposition and how it contributes to genome dynamics
5
remains controversial without direct, real-time measurement in live cells. Here, using a suite of fluorescent reporters coupled to transposition in live
Escherichia coli
, we show that IS608-TnpB causes increased transposon activity, and assists in preventing transposon loss from host genomes. Analyzing our results through a mathematical model of transposon dynamics, we discuss the multifaceted roles it may play in transposon regulation. The mutually beneficial transposon-TnpB interaction may explain the prevalence of
tnpB
, creating conditions for the appropriation of TnpB’s RNA-guided endonuclease activity for adaptive immunity.Phylogenetic evidence suggests that
tnpB
, one of the most numerous genes found in nature, is the ancestral form of CRISPR-Cas enzymes and played a critical role in the evolution of adaptive immunity. However, the role TnpB plays in transposition that has contributed to its wide distribution remains unclear. Here, we use a unique approach that couples fluorescent reporters to transposition to non-perturbatively quantify transpositional dynamics in live cells. In contrast to previous indirect methods suggesting that TnpB suppresses transposition, our results instead clearly demonstrate that TnpB significantly increases transposition rates and enhances transposon retention within the host genome, resulting in a mutually beneficial interaction between transposons and TnpB that can account for its wide distribution.
Inversions Can Accumulate Balanced Sexual Antagonism: Evidence from Simulations and Drosophila Experiments
Authors: McAllester Christopher S. , Pool John E.
Published: December 2023

Chromosomal inversion polymorphisms can be common, but the causes of their persistence are often unclear. We propose a model for the maintenance of inversion polymorphism, which requires that some variants contribute antagonistically to two phenotypes, one of which has negative frequency-dependent fitness. These conditions yield a form of frequency-dependent disruptive selection, favoring two predominant haplotypes segregating alleles that favor opposing antagonistic phenotypes. An inversion associated with one haplotype can reduce the fitness load incurred by generating recombinant offspring, reinforcing its linkage to the haplotype and enabling both haplotypes to accumulate more antagonistic variants than expected otherwise. We develop and apply a forward simulator to examine these dynamics under a tradeoff between survival and male display. These simulations indeed generate inversion-associated haplotypes with opposing sex-specific fitness effects. Antagonism strengthens with time, and can ultimately yield karyotypes at surprisingly predictable frequencies, with striking genotype frequency differences between sexes and between developmental stages. To test whether this model may contribute to well-studied yet enigmatic inversion polymorphisms in
Drosophila melanogaster
, we track inversion frequencies in laboratory crosses to test whether they influence male reproductive success or survival. We find that two of the four tested inversions show significant evidence for the tradeoff examined, with
In(3R)K
favoring survival and
In(3L)Ok
favoring male reproduction. Additionally, all inversions show survival differences between sexes, and paternal success depends on maternal genotype. Based on this work, we expect that balancing selection on antagonistically pleiotropic traits may provide a significant and underappreciated contribution to the maintenance of natural inversion polymorphism.

Published: December 2023

O mapeamento da rede de produção acadêmica é importante para representar a atividade científica em uma área do conhecimento. O objetivo desse estudo foi mapear as redes de colaboração científicas relativas ao disclosure contábil e as teorias subjacentes. Utilizou-se o método bibliométrico de caráter exploratório com o uso das técnicas de análise de rede de autoria em documentos extraídos da base Scopus da Elsevier no período de 1968 a 2019. A amostra foi composta por 486 documentos, sendo a análise auxiliada pelo software Vosviewer. Os resultados indicam que os grupos com vinculações mais significativas nas redes de autoria foram representados pelos autores Qingliang Tang (Western Sydney University), Lúcia Lima Rodrigues (Universidade do Minho) e Dennis M. Patten (Illinois State University) além de seus respectivos coautores. As teorias mais referendadas foram: a Teoria da Legitimidade, a Institucional, da Agência e a dos Stakeholders. Na análise de proximidade entre campos de investigação foram identificados três clusters, um relativo à governança corporativa e a responsabilidade social, outro vinculado a divulgação do carbono e as mudanças climáticas e um terceiro que constiuí um elo de discussão entre o disclosure obrigatório e voluntário. As evidencias apontam para a existência de grupos internancionais  de pesquisa com uma certa coesão de lações entre países e pesquisadores no norte global. As implicações dos resultados apontam para a necessidade de fortalecimento dos laços dos pesquisadores e instituições dentro e fora do país nesse campo de investigação, especialmente ao considerar o pais como estratégico no tange aos desafios da crise climática e ambiental.

Published: December 2023

Existem muitos trabalhos sobre os fatores críticos de sucesso para a implementação do gerenciamento de projetos nas organizações, por ser um tema importante e recorrente nos projetos de TI. Entre esses fatores, o gerenciamento do escopo é destacado como fundamental para o sucesso do projeto, por ser um aspecto relacionado diretamente as competências de projetos, eficiência, eficácia e aspectos de maturidade organizacional. A pretotyping pode ser considerada como alternativa no tratamento desse fator, pois permite simular a criação ou a usabilidade de um protótipo ou produto final de forma rápida, barata e simples. Por ser um termo “novo”, encontramos poucas informações sobre o assunto. Este artigo tem com objetivo identificar os principais problemas que ocorrem no gerenciamento do escopo dos projetos de TI e apresentar um modelo de atendimento adequado para tratamento e prevenção desses problemas. Para esse trabalho foi feita a análise do processo de gerenciamento do escopo indicado pelo PMI (Project Management Institute), juntamente com os principais problemas destacados por autores em outros estudos versus as soluções que são aplicadas nesses projetos. Através dessa análise, foi possível elaborar e apresentar uma proposta contendo melhorias nesse processo aplicando o conceito de pretotyping.
Frequency of Preneoplastic and Neoplastic Lesions in Cholecystectomy Specimen from a Tertiary Care Hospital in Uttar Pradesh, India: A Cross-sectional Study
Authors: . Umika , Fatima Afreen , Garg Kanchan , Singh Vijai
Published: December 2023

Introduction: Cholelithiasis is known to cause a spectrum of changes, including inflammation in the gallbladder wall, cholesterolosis, atrophy, metaplasia, dysplasia, polyps, and eventually cancer. Gallbladder Carcinoma (GBC) is a rare and highly fatal malignancy. Aim: To determine the frequency of preneoplastic and neoplastic lesions, along with demographic and clinical aspects of different gallbladder lesions. Materials and Methods: This cross-sectional study was performed on 788 patients who underwent elective cholecystectomy for gallbladder disease at Hind Medical College, Sitapur, Uttar Pradesh, India, from August 2017 to October 2021. All patients underwent a history and physical examination, followed by routine laboratory tests and other investigations, including full abdominal ultrasound. Histopathologic evaluation of the gallbladder specimen was also performed after surgical resection. Categorical variables were presented as numbers and percentages (%), while continuous variables were presented as mean ± Standard Deviation (SD). Results: A total of 788 cholecystectomy specimens were analysed. The mean age of the patients was 42.49±1.39 years with female predominance 640 (82.05%). The majority of cases were between 40-49 269 (34.13%) and 60-69 399 (50.63) years of age. Preneoplastic changes were found in 764 (96.96%) cases, while neoplastic pathology was evident in 24 (3.04%) cholecystectomy specimens. The most commonly observed preneoplastic change was chronic cholecystitis in 532 (67.54%) cases. Other lesions associated with chronic cholecystitis were cholesterolosis in 76 cases (9.64%), xanthogranulomatous cholecystitis in 34 cases (4.31%), follicular cholecystitis in 30 cases (3.80%), and GBC in 24 cases (3.04%). Conclusion: This study observed that chronic cholecystitis and cholesterolosis, followed by xanthogranulomatous cholecystitis, were associated with metaplastic changes in gallbladder pathologies. It is believed that metaplasia-dysplasia could be linked to GBC. Therefore, routine microscopic examination is required for all cholecystectomies. However, further studies on gallbladder carcinogenesis are needed.
ПИСЬМЕННЫЕ ИСТОЧНИКИ HISTORIA NORMANNORUM ДУДОНА СЕН-КАНТЕНСКОГО (ПОСТАНОВКА ВОПРОСА), "Средние века"
Authors: Ярославцева А.Ю.
Published: December 2023

В статье предпринята попытка идентифицировать письменные источники хроники франкского монаха Дудона Сен-Кантенского, созданной в начале XI в. и озаглавленной им «De moribus et actis primorum Normaniae ducum». Она известна также как «Historia Normannorum» и является первым по времени сочинением, посвященным истории Нормандии. Хронист опирался прежде всего на устные сообщения, полученные им от герцогов Нормандии и их окружения, что привлекало многих исследователей. Вопрос о письменных источниках Дудона изучен, напротив, очень мало, что, в частности, мешает понять причины ряда лакун в его тексте и несоответствия некоторых из сообщаемых им сведений данным, содержащимся в других источниках этого времени. Это обстоятельство на долгие десятилетия дискредитировало сочинение Дудона в глазах исследователей. Изучая круг письменных источников, которые Дудон мог использовать при написании «Истории норманнов», автор статьи уточняет замысел хрониста и особенности его работы с имевшимся у него материалом, что помогает по достоинству оценить оригинальность его работы и надежность сведений, содержащихся в его сочинении.
ГИДРОХИМИЧЕСКИЙ СОСТАВ ПОДЗЕМНЫХ ВОД И ИХ ПРИМЕНЕНИЕ В РЫБОВОДЧЕСКИХ ХОЗЯЙСТВАХ, "Наука юга России"

Published: December 2023

В последние несколько лет в рыбоводческую деятельность вовлекается все большее количество малых и средних фермерских хозяйств. При этом в качестве источника воды как одного из самых важных критериев успешности хозяйств все чаще используются грунтовые, подземные воды и водоемы карьерного типа, гидрохимический состав которых заметно отличается от стандартных, рекомендованных для использования в аквакультуре в общем и в рыбоводстве в частности. Для определения химического состава вод в Ростовской области, в бассейне р. Дон, отобраны пробы 17 и 19 мая 2023 г. В районах рыборазведения набраны образцы воды с целью определения содержания солей, негативно сказывающихся на развитии рыбы. В число исследуемых водоемов вошли Соленое озеро рыбохозяйственного комплекса «Дон-Батюшка» (г. Батайск), обводненный карьер общества с ограниченной ответственностью «ОФИ» (с. Кулешовка), пруды в с. Отрадовка, а также подземные воды из скважины в с. Орловка (Азовский район). Проведено сравнение используемых в хозяйстве вод с образцами, ранее отобранными в скважинах с. Кагальник и с. Займо-Обрыв. Образцы вод отобраны из подземных источников острова Свиного, а также из природных водоемов – рек и прудов (р. Ея). Проведено сравнение химического состава вод рыбохозяйственного назначения и вод подземных источников, а также рек Дон и Кагальник при разной гидрометеорологической обстановке. При проведении исследований гидрохимического состава воды обнаружено превышение требований по показателям качества воды при разведении и выращивании осетровых практически по всем основным показателям. Содержание некоторых соединений, например таких, как сульфат-ион (SO4), в грунтовых водах может достигать более 62,5 % (14 62,9 %) от общей минерализации воды, в ряде случаев количество сульфат-ионов более чем в 70 раз превышает рекомендуемую норму. Добавление в технологическую схему систем с оборотным водоснабжением станций обратного осмоса помогает снизить негативный эффект от избыточной минерализации вод.
НОВОЕ МЕСТО ЗИМОВКИ СЕРОГО ГУСЯ ANSER ANSER (ANSERIFORMES) НА ЮГЕ ЕВРОПЕЙСКОЙ РОССИИ, "Наука юга России"
Authors: Лебедева Н.В.
Published: December 2023

Приведены данные о новом месте зимовки серого гуся Anser anser (Linnaeus, 1758), гнездящегося на Западном Маныче (Весёловское водохранилище, 47°06 с.ш., 40°54 в.д.), зарегистрированном в Крыму в 2023 г. Регистрация положения гусей во время зимовки за пределами района размножения была подтверждена мечением гусей металлическими кольцами, цветными ошейниками (желтый, номера RXXX) и GPS-GSM трансмиттерами (ECOTONE). С 2015 по 2022 г. серые гуси зимовали только на водоемах Предкавказья: на Краснодарском, Варнавинском, Крюковском водохранилищах, в кубанских и приморско-ахтарских плавнях в 240 300 км от района размножения. Впервые зимовка весёловской группировки серых гусей зарегистрирована на внутренних водоемах Керченского полуострова (Крым) в 475 км от места рождения на основании локализации гуся, помеченного трансмиттером, в 2022/2023 гг. Выдвинута гипотеза о том, что появление новой зимовки связано с повышением охотничьего пресса на серого гуся в Предкавказье. В 2021 г. серый гусь был внесен в Красную книгу РФ (29 административных районов, в том числе Республика Крым). Исключение составил юг Европейской России, включая Краснодарский край, где зимует серый гусь из группировки с Западного Маныча. Охота на серого гуся сместилась из других регионов на юг Европейской России. Практически одновременно с внесением серого гуся в Красную книгу РФ сроки осенней охоты, завершавшейся в прежние годы 31 декабря, были продлены до 20 января, что усилило пресс на зимующую группировку. Около трети помеченных серых гусей, возвраты от которых были получены, были добыты в Краснодарском крае в январе. Таким образом, перемещение части зимующей группировки серого гуся на Керченский полуостров, в зону покоя, позволит ей сохраниться в условиях усиливающегося охотничьего пресса. Вероятно, создание заповедной территории в Восточном Приазовье позволит сохранить серого гуся в России.
Social Media as a Potent Factor in Promoting Awareness about Swachh Bharat Abhiyaan: A Critical Analysis
Authors: Gupta Juhi , Bakshi Ritu
Published: December 2023

Social media, as a new form of digital communication, has changed the way people think about education, health, banking, the environment, and other topics. The social media act as a catalyst in enlightening the masses on issues related to the environment like climate change, global warming, the green peace movement, depletion of the ozone layer, greenhouse gases effect, acid rain, and so on. It has been playing a very important role in spreading the Swachh Bharat Mission to the nook and corner of the country and changing the behavior of the public towards cleanliness. This study explores the significant role of social media in promoting awareness and driving engagement for social initiatives, focusing on the Swachh Bharat Abhiyaan in India.  The Swachh Bharat Abhiyaan (Clean India Mission) is a government-led initiative aimed at achieving a clean and open-defecation-free India. Social media platforms have emerged as powerful tools for communication and information dissemination, making them valuable for promoting social causes. In the present study, the investigator conducts a meta-analysis of a research paper related to Swachh Bharat Abhiyan, mass media, and social media and seeks to explore mass media and social media contribution to Swachh Bharat Abhiyan. Findings of the study revealed that social media is a beneficial instrument for the Clean India Campaign and Television is viewed as an efficient medium of communication among the masses. In addition to it, the media has the power to propagate and build public understanding about cleanliness and its benefits, and to provide the proper conditions for behaviour changes.

Published: December 2023

An experiment was conducted to evaluate the cold tolerance ability of ten boro rice genotypes in the laboratory conditions for suitability of growing under low temperature stress. The experiment was laid out in Factorial CRD and the low temperature regimes was provided under controlled environment (Walk-in cold chamber by Saveer Biotech Limited) for germination studies that could maintain the specific low temperature. The experiment was conducted in the Department of Crop Physiology and Agricultural Biotechnology, Assam Agricultural University, Jorhat, Assam, India. The germination tests were conducted under four different temperature regimes where seed germination under ambient (T4=28 ± 0.2oC) was considered as control. Low-temperature treatments were provided by the growth chamber at three different levels of low temperature viz. (T3=10-12°C), (T2=7-9oC) and (T1=5-6°C). Per cent germination, germination index, shoot length, length of longest root and seed vigour index were considered for the study. The germination percent, germination index, shoot length, length of longest root and seed vigour index was recorded highest under ambient condition (T4) irrespective of all the genotypes. Seeds grown under T3 showed considerable germination values only after 28 days of germination studies, whereas T1 and T2 showed no germination. The study revealed that amongst all the ten genotypes, Kanaklata and Sona Mahsuri revealed superior performance in germination percentage, germination index, shoot length, length of the longest root and seed vigour index. In the correlation studies, germination % was significantly correlated with germination index, shoot length, length of the longest and SVI at 5% probability level. GI was also positively and significantly correlated with Shoot length (SL), Length of longest root (LLR) and Seed Vigour Index (SVI). The present study revealed that Sona Mahsuri and Kanaklata was found to be the ideal genotypes for germination under low temperature (10-12oC). Therefore, Farmers growing boro rice under low temperature regimes could take the opportunity of selecting the varieties viz. Kanaklata and Sona Mahsuri for higher yield.

Published: December 2023

Deterioration of soil health, expensive and unnecessary inputs, water-intensive/water-pollutive, lethal and ecologically harmful farming practices in chemical farming do no good to agricultural advancement, and to public health. To reduce ill effects of chemical farming, a long term experiment is conducting to study the effect of organic manures and chemical fertilizers on yield, quality and soil health in finger millet since kharif 2013 at Agricultural Research Station, Perumallapalle, ANGRAU, Andhra Pradesh, India with a test variety Vakula. The experiment consists of two treatments viz., organic farming and chemical farming. Recommended dose of manures and fertilizers were applied to organic and inorganic plots, respectively in each season. The data on yield parameters, yield, quality and soil properties was collected and statistically analyzed with paired t test by using SPSS 2.0. The results revealed that during kharif 2022, significantly the highest grain yield (31.62 q ha-1), straw yield (84.06 q ha-1), number of tillers/plant (1.9), were recorded with chemical farming. The highest N, P and K uptake by plant at flowering was also recorded with chemical farming during both Kharif and Rabi seasons. Regarding quality, high protein, total phenol and tannin content had been recorded with organic farming. Build up of organic carbon, available nitrogen and phosphorus were noticed in post harvest soil when compared initial values (kharif 2013.). Soil enzymatic activity and microbial population was also higher with application of organic manures and biofertilizers than chemical fertilizers. The grain yield of organic farming plot was comparable with chemical farming after nine years of experimentation.

Published: December 2023

The dominant agricultural system in India is the rice-wheat system, and the problems posed by climate change and declining soil health are endangering the system's sustainability. High yields from the irrigated rice-wheat system have resulted in a substantial amount of wasted food. In northwest India, burning rice straw is a frequent practice that results in significant air pollution that is harmful to human health and nutritional losses. Crop residue management improvements should help achieve sustainable productivity, enable farmers to minimize nutrient and water inputs, and lower the risk associated with climate change-all of which will help prevent straw burning. The rice-wheat system's nutrition management will benefit from the prudent application of crop residues, which contain substantial amounts of plant nutrients. Long-term research on residue recycling has shown improvements in the soil's chemical, biological, and physical health. Another viable approach to managing crop residues is to use some of the excess residues to make biochar, which can be added to the soil to enhance its health, maximize its ability to use nutrients, and reduce air pollution. Mushroom cultivation may convert non-edible crop leftovers into a nutritious food source, surface mulch can suppress weed growth and retain soil moisture, and compost and biofuel can all be made from these materials. The decomposition of residues considerably boosts the soil's organic carbon and nitrogen levels. This review looks at the residues that can form in a rice-wheat farming system and how those residues can be effectively managed.

Two bacterial isolates from the mangrove’s soil were isolated and screened for xylanase production. Screened isolates designated as AS1 and AS2 were identified by sequencing and found to be Bacillus altitudinis and Bacillus licheniformis. The highest xylanase activity recorded from Bacillus altitudinis is 82.664 units per ml and from Bacillus licheniformis is 153.59 unitsper ml at pH 4.0. Purification of the crude enzyme was done by molecular sieve chromatography and molecular weight was estimated by the SDS PAGE method. The molecular weight of xylanase was noted as 43 and 40 kDa respectively. Temperature 40°C and pH 4.0 was found to be optimum for purified xylanase enzyme. Purified xylanase was active in broad pH and temperature range. Purified xylanase activity was repressed upon incubation with FeSO4 solution. Application of purified xylanase was done in clarifying different fruit juices.The results of fruit juice clarification indicate the escalation in the sugar concentration and transparency in the juices. Percent transmittance of fruit juices showed 25.11%, 75.82%, 52.40%, 40.09%, and 30.21% for apple, orange, mousambi, pineapple, and kiwi respectively, with Bacillus altitudinis xylanase. while 44.31%, 80.12%, 72.11%, 33.00%, and 21.42 for apple, orange, mousambi, pineapple, and kiwi respectively, with Bacillus licheniformis Xylanase.

This study aimed to evaluate the effect of 1-methylcyclopropene (1-MCP) applied as pre-cutting, post-cutting, and double application (before and after cutting) on the changes in the firmness and quality parameters of fresh-cut ripe ‘Maradol’ papaya. Four treatments (T1 T4) were used. T1 (Control treatment): Fresh-cut ‘Maradol’ papaya slices (Control treatment or T1) dipped in 1% CaCl2 for 2 min, then sprayed with 0.1% iso-ascorbic acid and 0.05% sorbic acid. One part of the T1 slices were treated with 1000 nL/L of 1-MCP for 12 h at 10 °C (T2). T3: Fresh-cut papaya slices treated with the same additives from the whole papaya treated 1000 nL/L of 1-MCP for 12 h at 20°C. T4: Fresh-cut papaya with additives treated with 1-MCP before and after cutting. All slices were packed in polypropylene trays with a perforated cover and stored at 4 ºC. T3 and T4 slices exhibited lower firmness loss and decreased activity of pectin methylesterase, polygalacturonase, and beta-galactosidase compared to T1 and T2 slices. Moreover, T3 and T4 slices had low translucency and microbial load, complying with the European Union limit (3 log CFU/g). No significant variations in acidity, pH, and total soluble solids were noted between treatments, but higher color values were obtained in T3 and T4 slices. To the best of our knowledge, this is the first study where the combining effects of additives and 1-MCP application before and after cutting extended the shelf-life of fresh-cut ‘Maradol’ papaya for up to 13 days at 4 °C, twice the duration reported by others.

Olives and its oil are considered an imperative element of diet due to their excellent nutritional quality. Geographical factors (i.e., geology, slope, elevation and temperature) and genetic variability in different olive cultivars influence plant growth, yield, oil and profiling of fatty acids. The prime objective of this investigation was to demonstrate the prodigious consequences of high temperature on the growth, production, and fatty acid composition of four olive cultivars (Coratina, Frantoio, Ottobratica and Leccino) at three different geographical locations (BARI, IOF, HRS) with the range of 460-751 m altitude during the year 2017 and 2018. The study has been carried out to investigate different parameters such as climatic conditions (rainfall and temperature), phenological attribute and yield traits (fruit set, fruit weight, yield, and oil content), and oil quality and profiling of fatty acids (free fatty acid contents, peroxide, palmitic acid, palmitoleic acid, oleic acid, linoleic acid, and linolenic acid). The results indicated a positive correlation of yield with rainfall and negative with the temperature was observed among olive cultivars. The results showed higher rainfall (1189 mm) and temperature (37.51 °C) at location-1 and lower rainfall (525 mm) and temperature (36.05 °C) at location-3. Coratina and Frantoio depicted significantly higher fruit set and yield in warmer climatic regions (Location-1 and Location-2) while Leccino and Ottobratica showed better results in the cooler region. Higher oil content was found in Frantoio and Coratina at location-3 among other locations and other cultivars. Overall, the lowest free fatty acid value was exhibited in Coratina and the highest in Ottobratica at all locations in both seasons. The contents of peroxide were observed higher in Leccino and lower in Coratina at all locations. The results revealed less variation among fatty acid composition in cultivars and seasons, however, palmitic acid, palmitoleic acid and oleic acid contents were found higher at location-2, linoleic acid at location-3, and linolenic acid at location-2 in all four olive cultivars. Custer analysis revealed two main groups and group-I contained two subgroups (A and B) while group-II contained three subgroups (C, D and E). In principal component analysis (PCA), PC1 axis had Leccino-L3, Leccino-L1, Frantoio-L1, Ottobratica-L1, Coratina-L1, and Leccino-L3 and explained 91.99% of the total variation. Therefore, geographic location influence growth, yield and olive oil quality attributes.

Packaging is the main source of polluting plastic waste. Out of the total volume of plastic waste worldwide, the majority corresponds to food packaging. Biodegradable films have been used in a large number of applications across industrial sectors due to their property  versatility and environmental factors. There is a growing interest in the search for packaging materials from renewable sources that prove to be functional for food preservation. Among the polymers used, starch has garnered the most attention due to its abundance in nature and biodegradable quality; it is also renewable and low-cost. A methodology was established to increase the shelf life of perishable fruits (blackberry) from 7 to 14 days by adding starch, chitosan, and roselle extract. These biopolymers synergistically contribute by providing support, antibacterial, and antioxidant properties, respectively. The use of chitosan and roselle extract were key to the achievement of this work’s goals, as proven by FT-IR, TGA, SEM, contact angle, and microbiological analyses. The present work focuses on the use of three elements that have not been studied together in biofilm design to preserve fruits.

The varieties creole are traditionally grown plant, adapted in places where the crops are developed and present in seeds banks of many famers. Thus the objective of this study was to investigate the performance of the germination process and possible toxic effects. Were used seeds of creole cultivars of beans (Phaseolus vulgaris L.), using different concentrations of aluminum. We used a randomized completely design with four repetitions of 25 seeds and the treatments were distributed in 4 x 5 factorial scheme, consisting of four bean cultivars (Carioca, Butter, Black, Red) and five concentrations (0.0, 2.5, 5.0, 7.5, and 10.0 mg L-1) of aluminum sulfate. The characteristics analyzed were percentage of germination, percentage of abnormal seedlings, germination speed index, root length, length of the base of the seedling to the hypocotyl, hypocotyl length of seedlings to the epicotyl, root dry mass and shoot dry mass.  The variables germination percentage and germination speed index were not affected by the toxic effect of aluminum. The variables percentage of abnormal seedlings, root length and shoot showed a significant reduction with the increase in aluminum sulfate concentrations, thus showing a greater correlation between them.
