Caregiving strategies, parental practices, and the use of Facebook groups among Israeli mothers of adolescents

Facebook offers a “village” for mothers to come together and seek and share parenting information, but while there has been substantial research examining both positive and negative aspects of parents’ Facebook use, there is no research on use of Facebook by mothers of adolescents and its association with parent-adolescent relationships. Given the intense challenges of raising adolescents and the dearth of research into potential benefits and drawbacks of mothers of adolescents seeking support from Facebook, we sought to fill this gap by focusing on the caregiving and parenting practices of mothers of adolescents who were members of mothers’ groups on Facebook. The sample included 74 Israeli dyads of mothers (Mage = 43.73, SD = 4.41), who participated in Facebook groups for mothers and their adolescent children (Mage = 12.26, SD = 3.11) during 2019. Mothers reported on their Facebook use and caregiving strategies. The adolescents answered a parenting practices questionnaire. It was found that higher permissiveness and greater psychological intrusiveness were related to higher use of Facebook by the mothers. Among mothers who were high on hyperactivation, greater permissiveness and psychological intrusiveness were related to higher Facebook use to a greater extent than among mothers who were low on hyperactivation. Alongside Facebook’s benefits as a community for mothers come serious risks for some mothers. As research in this area grows, an examination of the characteristics of Facebook use by mothers of adolescent children involved in Facebook mothers’ groups is meaningful.
Antimicrobial potential of kombucha against foodborne pathogens

The survival of foodborne pathogens under stressful food processing conditions and in host’s gastrointestinal tract has been widely reported to cause the outbreak of human diseases. Generally, antibiotics have been used to elimi-nate the microbial flora of foodborne pathogens. However, the overuse of antibiotics has contributed to the emergence and spread of multi-drug-resistant foodborne pathogens. Kombucha is a beverage prepared by fermenting sugared tea or other substrates with a symbiotic culture of yeasts and bacteria, and has been proved to fight food-borne pathogens and affect gastrointestinal microbial flora to prevent foodborne illnesses. In this context, this review primarily focused on microbiological and chemical compositions of kombucha obtained by fermenting different substrates. It further discussed the antimicrobial activity of kombucha, as well as potential antimicrobial agents found in kombucha, and the limitations of kombucha in the food industry. In addition, the need for developing antimicrobial agents from kombucha has been discussed for potential applications. The information provided in this review indicates that kombucha could serve as an alternative approach to control pathogens in place of using antibiotics.
SEMANTIC SEGMENTATION METHOD ACCELERATED QUANTITATIVE ANALYSIS OF THE SPATIAL CHARACTERISTICS OF TRADITIONAL VILLAGES

Abstract. Rapid investigation and quantitative analysis are crucial for heritage conservation and renewal design. As an important category of architectural heritage - traditional settlements - with their large number and complex spatial characteristics, their spatial character patterns are an important support to assist settlement conservation and renewal design. However, the current means of analysis often requires manual data collection, secondary mapping of the collected data, extraction of individual elemental patterns and village boundaries. Then settlement boundary form, settlement density will be calculated by mathematical methods. The above methods are inefficient and prone to manual mapping errors, making it difficult to quantify and analyze a large number of traditional villages in a short period of time. Semantic segmentation is a computer vision technique for quickly segmenting different objects. Based on the collected remote sensing data of traditional villages, this paper established a dataset of semantic segmentation of spatial features of traditional settlements, segmenting village buildings, water systems, roads and plants. Using Transfer learning, data augmentation and other methods, a model was trained that can automatically segment elements of the villages. From the national traditional villages that have been announced so far, 60 traditional villages from different regions in the north and south were selected for analysis. The experiments show that the model established in this paper has an accuracy rate of above 86% in segmenting elements of villages, can effectively identify the location of different elements in remote sensing images, effectively improves the quantification rate of spatial features of settlements and saves the cost of mapping and data transcription. The results of the spatial characteristics of the 60 villages studied in this paper can also provide some theoretical basis and inspiration for the study, conservation, design and transformation of traditional villages.
Effects of post-veraison irrigation on the phenolic composition of Vitis vinifera L. cv. ‘Xinomavro’ grapes

‘Xinomavro’ (the second planted red Greek variety behind ‘Agiorgitiko’) generally produces wines that are light in colour but with increased astringency, possibly related to grape flavonoid amount and composition; although irrigation is accepted as an effective means to enhance grape phenolic maturity, its role has not yet been sufficiently studied in the case of Xinomavro. This study aimed to determine the effect of post-veraison irrigation on berry anthocyanin and proanthocyanidin amount and composition, of field-grown Xinomavro vines (Vitis vinifera L.), under the typical summer conditions of Northern Greece. In a 10-year-old Xinomavro vineyard, two post-veraison watering regimes were applied—irrigation starting 20 days after veraison (mid-ripening irrigation, MRI) and irrigation starting immediately after veraison was completed (after veraison irrigation, AVI)—alongside non irrigated vines (NI), and vines irrigated continuously from berry set through harvest (continuous irrigation, CI). Proanthocyanidin composition was determined in both skins and seeds by employing phloroglucinolysis followed by HPLC-UV and MS detection (high-performance liquid chromatographic with tandem mass spectrometric and ultraviolet absorbance detection), and the anthocyanin profile was identified only in the skin extracts by HPLC-UV (high-performance liquid chromatographic with ultraviolet absorbance detection). Post-veraison irrigation increased yield parameters and reduced anthocyanin levels and the proportion of their stable forms (acylated vs. non-acylated, tri-oxygenated and methoxylated on the B-ring vs. di-oxygenated and hydroxylated), compared to NI vines; however, these effects were more pronounced in the case of early post-veraison irrigation (AVI) than late-season irrigation (MRI). Irrigation also increased the mean Degree of Polymerization (mDP) and prodelphinidin percentage of skin tannins and decreased mDP of seed tannins. In the light of the necessity to control the accelerated ripening under the increasingly hotter and drier climatic conditions, late irrigation (MRI) might provide a solution to avoid excessive sugar levels and allow a slightly higher yield without significant reductions in berry phenolic content. The results suggest that the optimisation of the timing of irrigation could provide an effective adaptation strategy to climate change in Mediterranean viticultural areas.
Simulated Gastrointestinal System Study of Centella asiatica Extract-loaded Gelatin Nanoparticles on Antioxidant and Antimicrobial Activities

The aim of this study is to improve antibacterial activity and antioxidant activity of Centella asiatica in simulated gastrointestinal system. Gelatin one-step and two-step desolvation nanoparticle methods were used to prepare C. asiatica-loaded gelatin nanoparticles (CGNP) on three different ratio of 95% ethanolic C. asiatica crude extracts:Gelatin (1:2, 1:3, and 1:4). One-step CGNP (OSCGNP) was tested on antibacterial activity by using well agar diffusion method with different concentrations (100, 200, and 300 μg/ml) against seven foodborne pathogens and antioxidant activity by using DPPH method. The inhibition zones of OSCGNP showed highly significant effective at concentration of 300 μg/ml in oesophagus-stomach section against E. coli ATCC25822 and B. subtilis respectively. In addition, S. aureus, S. enterica Enteritidis (human), and S. enterica 4,5,12:i:(human) US clone were strongly inhibited by OSCGNP at concentration of 100 μg/ml. The highest inhibition zone of OSCGNP was 1.00±0.17 cm at pH 2.0 using gelatin one-step desolvation method. The highest antioxidant activity was 22.70±4.69 μg GAE/ml per 10 mg of OSCGNP with ratio of 1:2 occurred in stomach at pH 2.0. Moreover, antioxidant activity of CGNPs (One-step and two-step gelatin nanoparticles) were dropped when they reached duodenum section. The results indicated that CGNPs gave lower antioxidant activity than crude extract.
Neuropsychiatric Genetics of Psychosis in the Mexican Population: A Genome-Wide Association Study Protocol for Schizophrenia, Schizoaffective, and Bipolar Disorder Patients and Controls

No large-scale genome-wide association studies (GWASs) of psychosis have been conducted in Mexico or Latin America to date. Schizophrenia and bipolar disorder in particular have been found to be highly heritable and genetically influenced. However, understanding of the biological basis of psychosis in Latin American populations is limited as previous genomic studies have almost exclusively relied on participants of Northern European ancestry. With the goal of expanding knowledge on the genomic basis of psychotic disorders within the Mexican population, the National Institute of Psychiatry Ramón de la Fuente Muñiz (INPRFM), the Harvard T.H. Chan School of Public Health, and the Broad Institute’s Stanley Center for Psychiatric Research launched the Neuropsychiatric Genetics Research of Psychosis in Mexican Populations (NeuroMex) project to collect and analyze case-control psychosis samples from 5 states across Mexico. This article describes the planned sample collection and GWAS protocol for the NeuroMex study. The 4-year study will span from April 2018 to 2022 and aims to recruit 9,208 participants: 4,604 cases and 4,604 controls. Study sites across Mexico were selected to ensure collected samples capture the genomic diversity within the Mexican population. Blood samples and phenotypic data will be collected during the participant interview process and will contribute to the development of a local biobank in Mexico. DNA extraction will be done locally and genetic analysis will take place at the Broad Institute in Cambridge, MA. We will collect extensive phenotypic information using several clinical scales. All study materials including phenotypic instruments utilized are openly available in Spanish and English. The described study represents a long-term collaboration of a number of institutions from across Mexico and the Boston area, including clinical psychiatrists, clinical researchers, computational biologists, and managers at the 3 collaborating institutions. The development of relevant data management, quality assurance, and analysis plans are the primary considerations in this protocol article. Extensive management and analysis processes were developed for both the phenotypic and genetic data collected. Capacity building, partnerships, and training between and among the collaborating institutions are intrinsic components to this study and its long-term success.

Study of Microwave Technique in Hot Pepper Seed by Different Solvents with an Assessing Antioxidant and Antibacterial Properties

Chili pepper seed (CPS) is rich in nutrients and phytochemical particularly oil which could possess antimicrobial and antioxidant properties. Using novel techniques such as microwave assisted extraction (MAE) with solvents could be useful to extract these materials. The objectives of this study are to develop and evaluate antioxidants (and antibacterial activities of the hot seed pepper oil extracts using both water and ethanol solvents with MAE as novel techniques in relation to its ability to extract antioxidant and antibacterial compounds. Chili pepper seed (CPS) was obtained from the Kahramanmaraş, Turkey. CPS was extracted with water and ethanol and assessed for anti-oxidants activity via assessing total tannin, total phenol, total flavonoid and total anthocyanin and antimicrobial properties via assessing inhibition zone and minimum inhibitory concentration. Both yield extraction and total anthocyanin values extracted with water were 38.4 and 40.075% respectively and are higher significantly (p<0.01) higher than ethanolic extraction. On the other hand, total tannin, total phenol and total flavonoid values were 0.0575, 1.80700 and 0.26350 μM respectively which were significantly (p<0.01) higher with ethanol extraction. Ethanol had the greater free radical scavenging activity (IC 50 µg/ml) and more close standard butylated hydroxytoluene. Antimicrobial results indicated that water extracts was more effective against Staphylococcus aureus Pseudomonas aeruginosa, Enterococcus faecalis, Enterobacter aerogenes up to 24mm inhibition zone but, it is dose dependent. CPS oil extracts could be used as source of antimicrobial and antioxidants compounds with the aid of MAE. Ethanol has better yield and anthocyanin extraction and Free radical, whereas water extraction has effective antimicrobial activity.
Pharmacognostic, phytochemical and pharmacological aspects of Rosa x damascena Herrm. Georgian cultivar

Rosa x damascena Herrm. represents one of the most popular and important plants of the Rosaceae family. For ages, rose oil, rose water and extracts from its flowers were used in perfumery, cosmetics, aromatherapy, and medicine due to diverse pharmacological efficacy. Nowadays, special attention is paid to the valorization of wastes from the rose oil industry in order to fully recover potent biologically active compounds. The present study describes in detail the microstructural features of the flower petals and provides data on chemical composition and biological potency of the aqueous extract of rose oil waste from the R. damascena Georgian cultivar. Up to 25 constituents were detected by HPLC-MS in the extract, and the content of total flavonoids in the extract reaches 2.29%. Amongst them hyperoside is dominating, which content is not less than 1%. Pharmacological evaluation of the extract on "Hot plate" and carrageenan-induced oedema models in mice revealed analgesic (42%) and anti-inflammatory (67%) effects of the extract. As well, the extract revealed antiplasmodial activity against Plasmodium falciparum (3D7) strain (IC50 =20.31 µg/mL)
Bayesian Multilevel Models for Count Data

The traditional Poisson regression model for fitting count data is considered inadequate to fit over-or under-dispersed count data and new models have been developed to make up for such inadequacies inherent in the model. In this study, Bayesian Multi-level model was proposed using the No-U-Turn Sampler (NUTS) sampler to sample from the posterior distribution. A simulation was carried out for both over-and under-dispersed data from discrete Weibull distribution. Pareto k diagnostics was implemented, and the result showed that under-dispersed and over-dispersed simulated data has all its k value to be less than 0.5, which indicate that all the observations are good. Also all WAIC were the same as LOO-IC except for Poisson in the over-dispersed simulated data. Real-life data set from National Health Insurance Scheme (NHIS) was used for further analysis. Seven multi-level models were f itted and the Geometric model outperformed other model.
Non-governmental organization’s contribution to women small-scale farmers: A case study of Tchenzema ward, Morogoro, Tanzania

Tanzanian women play a vital role in the country’s development and industrialization. Tanzania’s agriculture is considered the country’s backbone, but women are the driving force behind small-scale farming. This study aims to identify the types of NGOs that support women, small-scale farmers, to investigate the effects of NGOs, and the challenges that small-scale farmers face in Tchenzema ward. The transition and growth model development theory, and patriarchy theory, were used in the study. The study revealed that poor transportation, crop illnesses and insects, lack of pesticides, price fluctuation, lack of energy, and high agricultural equipment prices are some of the issues faced by women small-scale farmers in Tchenzema ward. This study concludes that the lack of collaboration between the Tanzanian government and farmers causes farmers to only rely on NGOs. The government and non-governmental organizations need to support women small-scale farmers so as to solve the challenges, and raising the output, hence let the agriculture sector achieves its national aim of economic growth.
Α PATTERN-BASED AUGMENTED REALITY APPLICATION FOR THE DISSEMINATION OF CULTURAL HERITAGE

Abstract. Augmented Reality (AR) is more than an added value for Cultural Heritage (CH); it is vital for its sustainability, promotion and dissemination, increasing accessibility in CH even during difficult periods of time, like the Covid-19 pandemic. In order to be meaningful and engaging, an AR application should have the following characteristics: easiness of use, high-quality representations and compatibility. This paper presents a marker-less mobile AR application for the display and inspection of high-resolution 3D cultural assets, overlayed on a particular location in the real-world scene. Instead of predefined markers, an image captured by the user is exploited as a pattern for real-time feature matching, pose estimation and scene augmentation. Our approach is based on pure computer vision and photogrammetric techniques, implemented using native C++ and Java code for Android mobile platforms. It is built with the use of the OpenCV library and the OpenGL ES graphics API without any dependencies of AR Software Development Kits (SDKs). Therefore, it supports cross-vendor portability regarding mobile model devices and hardware specifications. The evaluation of the developed application examines the performance of various matching techniques and the overall responsiveness of processing and 3D rendering on mid-range and low-end smartphones. The results showcase the reliability and responsiveness of the pattern recognition as well as the potential of the 3D graphics engine to render and overlay complex 3D models balancing between visual quality and time. The proposed methodology is applied to the Ciborium of the church of St. Charalabos, located at St. Stephen’s Monastery in Meteora, Greece.
Utilization of Transfer Learning Model in Detecting COVID-19 Cases From Chest X-Ray Images
