IMPACT OF ORGANIC AND MINERAL FERTILIZER ON SOME PHYSICAL AND MECHANICAL CHARACTERISTICS OF POTATO TUBERS DURING STORAGE PERIOD

: This study was concerned with potato tubers in the experimental farm of Faculty of Agriculture, Menoufia University during the season 2020. The main objective of this work is to study the effect of with organic fertilizers comparing with using mineral fertilizers on some physical and mechanical properties of potato tubers during storage period. The experiments were conducted on two varieties of potatoes, (Diamond and Arizona). Two types of fertilizers were used in the cultivation of potato tubers, which were organic fertilizers and mineral fertilizers. The experimental treatments were divided into five treatments as follows: Control (without fertilizers) (T1) - 100% mineral fertilizer (T2) - 50% mineral fertilizer and 50% organic fertilizer (T3) - 25% mineral fertilizer and 75% organic fertilizer (T4) - 100% organic fertilizer (T5). The potato tubers stored at 4°C for 45 days. The reported results showed that, the best physical characteristics of potato tuber were found with fertilization treatment of (50% organic 50% mineral). Significantly found best among all treatments successive growth stages in term of maximum average weight (114 g), Shape index (331.30 %) and coefficient of friction with wood after 45 days of storage (.561). Where, the highest average value potato tubers firmness treatment (75% organic 25% mineral) is (114N).
Impacts of Diet on Reproductive Performance of Captive American Alligators (Alligator mississippiensis)

Simple Summary A significant issue in American alligator (Alligator mississippiensis) farming is the high rate of early embryonic deaths among captive eggs. Differences in fatty acid composition between wild and captive eggs have been noted, potentially due to maternal diets. A study was conducted at Golden Ranch using captive breeding alligators fed a specialized diet, supplemented with crawfish waste products. Results showed successful reproductive performance. The breeding females consistently achieved high hatch rates, and the resulting hatchlings exhibited comparable strength and size to their wild counterparts. This suggests that A. mississippiensis can be farmed effectively using captive breeders raised from artificially incubated wild eggs. Abstract Historically, there has been little success with the captive breeding of American alligators (Alligator mississippiensis) for both commercial and conservative purposes. This study, conducted at Golden Ranch in Gheens, LA, between 2016 and 2022, utilized a newly formulated commercial feed and practical dietary supplementation (crawfish waste products) to enhance egg production, fertility, and hatch rates. The primary focus of this study was to compare the outcome of this captive breeding program at Golden Ranch with a program conducted at Rockefeller Refuge (RR) between 1979 and 1984. Notable success was achieved in terms of reproductive performance in comparison to the captive breeding program conducted at Rockefeller Refuge. In this study, 16.1 hatchlings were produced per nest on Golden Ranch from captive breeders. Additionally, when wild nests from Golden Ranch were incubated in the same controlled environmental chambers, they produced an average of 16.3 hatchlings per nest. This comparison emphasizes the similarity in egg production between captive-bred A. mississippiensis and their wild counterparts. The findings of this study suggest that a closed farming system for A. mississippiensis can be established by employing captive breeders derived from artificially incubated wild eggs. Furthermore, American alligators raised in controlled environmental chambers during their initial three years of life demonstrated adaptability to captive conditions and tolerated stocking rates associated with farming conditions and served as breeding stock.
Effects of yeast and dried kratom leaves (Mitragyna speciosa [Korth] Havil.) supplementation on digestibility, rumen fermentation, blood metabolites and nitrogen balance in goats

Objective The objective of the experiment was to study yeast supplementation (yeast, Y) and dried kratom leaves (DKTL) on the digestibility, ruminal fermentation, blood metabolites and nitrogen balance in goats. Methods Four of 7 to 8 months old male crossbred (50% Thai Native-Anglo Nubian) goats with average liveweight 20±0.13 kg were randomly assigned according to a 2×2 factorial arrangement in a 4×4 Latin square design to receive four diets ad libitum basis. The study investigated the effects of two levels of yeast (Y) supplementation (Y, 0 and 0.5g/kg dry matter [DM]) along with two levels of DKTL supplementation (DKTL, 0 and 4.44g/kg DM). The experimental groups were as follows: T1 = control group with 0Y+0DKTL, T2 = 0Y+4.44 DKTL, T3 = 0.5Y+0DKTL, and T4 = 0.5Y+4.44 DKTL. Results The results showed that there were no interactions between Y levels and DKTL levels with respect to total DM intake, but there were significant effects (p<0.05) by levels of Y; goats receiving 0.05 g/kg DM Y had higher than goats fed 0.0 g/kg DM on average (kg/d). A percentage of body weight (% BW) and grams per kilogram of metallic weight (g/kg w0.75) had no influence on yeast levels and DKTL, but there was a difference (p<0.05) by yeast level Y at 0.5 g/kg DM, being higher compared to the non-supplemented group. Apparent digestibility coefficient of nutrition in the form of (DM, organic matter, crude protein, neutral detergent fiber, and acid detergent fiber) was an increased trend in the Y-level complementary group at 0.5 g/kg DM and DKTL at 4.44 g/kg DM, respectively. Protozoa populations decreased in the group receiving Y levels at 0.5 g/kg DM and DKTL levels at 4.44 g/kg DM when compared to group T1. The acetic acid concentration and methane gas generation decreased (p<0.05) in the group receiving Y levels of 0.5 g/kg DM and DKTL levels of 4.44 g/kg DM, while the amount of propionic acid increased (p<0.05). Conclusion Effects of feeding combinations of Y and DKTL supplementation on feed showed no interaction effect (Y×DKTL) on feed intake, rumen fermentation, bacterial and fungi population. The effect on protozoal populations was lower in the group that was supplemented with DKTL at 4.44 g/kg DM related to synthetic CH4 was reduced.
Assessment of Entrepreneurial Potential in the Training of a New Generation of Change Agents in Spain

The development of entrepreneurial potential in the training of school-age pupils is relevant for carrying out projects of an innovative and transformative nature. Entrepreneurial training is enacted through Spanish educational regulations, in relation to the development of the key entrepreneurial competence. Thus, a training programme in entrepreneurial potential for school-age students, who are considered as agents of change, was evaluated under the approach of “enterprise education pedagogy”. For this purpose, an experimental research study, pre-test and post-test, with a control and experimental group, was designed. The sample consisted of 1036 participants from eight autonomous communities in Spain. The data analysis was carried out by means of a t-test to compare the mean before and after the application of the programme on the total number of participants, as well as on the subgroups with and without entrepreneurial intentions. The results show that the PEIEO programme had a positive effect on entrepreneurial potential. The experimental group, compared to the control group, significantly increased their total score in the t-test, as well as for each dimension of entrepreneurial potential. Similarly, the participants considered to have entrepreneurial intentions further increased their entrepreneurial potential compared to the group considered to have no entrepreneurial intentions. Consequently, the results indicate that entrepreneurship education, in a holistic sense, has a relevant impact on entrepreneurial potential in a programme aimed at training agents of change.
Prevalence, and Risk Indicators of Coronal and Root Caries in Mexican Older Adults in Nursing Homes

Background Several factors are associated with coronal and root caries in older persons. The purpose of this study was to determine the experience, prevalence, and risk indicators (socioeconomic, sociodemographic, and dental variables) of coronal and root caries in older persons residing in nursing homes in Mexico. Methods A cross-sectional study was carried out in 227 dentate participants with natural teeth. Convenience sample, where all dentate residents were invited to participate. The dependent variables were coronal caries and root caries, which were determined through an oral clinical examination. The independent variables were sociodemographic factors, location, type of center, surfaces free of dental biofilm and calculus, surfaces with recession, retainers in contact with surfaces with recession, xerostomia, smoking, and the previous use of dental services. The binary logistic regression model was used in the analysis. Results The mean age of the participants in this study was 77.7±8.8 years, and 69.2% were women. Moreover, 71.8% live in long-term care facilities, and 48.0% live in Mexico City. The prevalence of coronal and root caries was found to be 67.8% and 50.7%, respectively. Being male and living in Mexico City were risk indicators for coronal caries, and with a 1% increase in surfaces with no biofilm, the risk decreased by 2%. Being widowed, having government or no social security, denture retainers, and coronal caries were risk indicators for root caries, while the utilization of dental services indicated lower risk. Conclusion Several variables that differ in nature were found to be risk indicators for coronal and root caries. Coronal caries increases the risk of root caries. Prevention should be aimed at identifying persons at higher risk, and dental care should be improved for persons living in long-term care institutions.
Exposure to Bisphenol A and Other Phenols in Neonatal Intensive Care Unit Premature Infants

Objective We previously demonstrated that exposure to polyvinyl chloride plastic medical devices containing di(2-ethylhexyl) phthalate (DEHP) was associated with higher urinary concentrations of several DEHP metabolites in 54 premature infants in two neonatal intensive care units than in the general population. For 42 of these infants, we evaluated urinary concentrations of several phenols, including bisphenol A (BPA), in association with the use of the same medical devices. Measurements We measured the urinary concentrations of free and total (free plus conjugated) species of BPA, triclosan, benzophenone-3, methyl paraben, and propyl paraben. Results The percentage of BPA present as its conjugated species was > 90% in more than three-quarters of the premature infants. Intensity of use of products containing DEHP was strongly associated with BPA total concentrations but not with any other phenol. Adjusting for institution and sex, BPA total concentrations among infants in the group of high use of DEHP-containing products were 8.75 times as high as among infants in the low use group (p < 0.0001). Similarly, after adjusting for sex and DEHP-containing product use category, BPA total concentrations among infants in Institution A were 16.6 times as high as those among infants in Institution B (p < 0.0001). Conclusion BPA geometric mean urinary concentration (30.3 μg/L) among premature infants undergoing intensive therapeutic medical interventions was one order of magnitude higher than that among the general population. Conjugated species were the primary urinary metabolites of BPA, suggesting that premature infants have some capacity to metabolize BPA. The differences in exposure to BPA by intensity of use of DEHP-containing medical products highlight the need for further studies to determine the specific source(s) of exposure to BPA.
Dispersed Relativistic Electron Precipitation Patterns Between the Ion and Electron Isotropy Boundaries

Relativistic electron precipitation to the Earth's atmosphere is an important loss mechanism of inner magnetosphere electrons, contributing significantly to the dynamics of the radiation belts. Such precipitation may be driven by electron resonant scattering by middle‐latitude whistler‐mode waves at dawn to noon; by electromagnetic ion cyclotron (EMIC) waves at dusk; or by curvature scattering at the isotropy boundary (at the inner edge of the electron plasma sheet anywhere on the nightside, from dusk to dawn). Using low‐altitude ELFIN and near‐equatorial THEMIS measurements, we report on a new type of relativistic electron precipitation that shares some properties with the traditional curvature scattering mechanism (occurring on the nightside and often having a clear energy/L‐shell dispersion). However, it is less common than the typical electron isotropy boundary and it is observed most often during substorms. It is seen equatorward of (and well separated from) the electron isotropy boundary and around or poleward of the ion isotropy boundary (the inner edge of the ion plasma sheet). It may be due to one or more of the following mechanisms: EMIC waves in the presence of a specific radial profile of the cold plasma density; a regional suppression of the magnetic field enhancing curvature scattering locally; and/or electron resonant scattering by kinetic Alfvén waves.

Fit indices compare the Estimated Model with the Saturated Model, affirming the model's accuracy in capturing observed data. Noteworthy results highlight the significance of education and workforce skills in mitigating high unemployment. The research contributes to the existing literature by providing empirical insights into the multifaceted factors influencing unemployment in the specific context of West Java.
INCREASED STOCKING DENSITY OF GIANT FRESHWATER PRAWN (Macrobrachium rosenbergii, de Man 1879) POSTLARVAE IN HAPA NETS WITH DIFFERENT SUBSTRATE POSITIONS

Decapod crustaceans is vulnerable to different environmental fluctuations. Thus, a variety of farming systems have been made by shrimp growers to solve these problems. This study assessed the survival, growth rate and interaction effect of stocking density and substrate positions of giant freshwater prawn ( Macrobrachium rosenbergii , de Man 1879) postlarvae when cultured in experimental framed hapa net installed in pond for 90 days. Three stocking densities were used in different substrate positions in 3 replicates stocked in 27 framed hapa nets. Results revealed lowest stocking density apparently showed better growth and bigger prawns compared to higher stocking density. Further, the mean growth of the commodity, size class distribution were significantly influenced by the stocking density. Survival rate, on the other hand, favored lower stocking density. No interaction effect among treatments was observed. Feed Conservation Ratio (FCR) improved with low stocking density. Moreover, densities of 20 pieces/m3 favored the better growth and survival rate of M. rosenbergii even with or without substrates. Shorter culture period affected the production yield.
Effectiveness of Xenograft and Porcine-Derived Resorbable Membrane in Augmentation of Posterior Extraction Sockets with a Severe Wall Defect. A Radiographic/Tomographic Evaluation

ABSTRACT Objectives The aim of the present prospective study was to evaluate, by means of intraoral periapical radiographs and cone-beam computed tomography, hard tissue changes after ridge augmentation procedures in posterior extraction sockets with severe wall defects. Material and Methods Twenty patients, with a non-restorable premolar/molar tooth and severe wall defect, were enrolled in the present study, and underwent single-tooth extraction. Extraction sites were grafted with porcine-derived bone covered by porcine-derived collagen membrane. Intraoral periapical radiographs and cone-beam computed tomography scans, obtained at enrolment, and 6 months after ridge augmentation procedures were analysed and compared. Results In the intraoral periapical radiographs, mean vertical bone gains detected at the distal, central and mesial aspects of the extraction sockets were 3.5 (SD 1.1) mm, 8.2 (SD 2.1) mm, and 3.9 (SD 1.7) mm, respectively. In the cone-beam computed tomography scans, the mean vertical bone gains detected at the more vestibular and more palatal aspects were 4.4 (SD 1.9) mm, and 3.3 (SD 2.8) mm, respectively. The mean horizontal bone gain was 3.5 (SD 1.6) mm. In all examined defects, mean vertical and horizontal bone levels showed a statistically significant increase (P < 0.05) at 6 months after extraction. Conclusions Within the limits of this study, the results suggest that porcine-derived bone graft covered by a collagen membrane can support significant vertical and horizontal bone gain at posterior post-extraction sockets with severe wall defects.
Assessment of Quality of Antenatal Care in Pregnant Women Delivered in Ain Shams University Hospitals

Background: Quality is the most important issue and the main predictor variable in developing as well as developed countries to achieve the Sustainable Development Goals (SDGs) and antenatal care. Objective: Determination of the quality of antenatal care service and associated factors at Ain Shams University Hospital, using longitudinal study design and questionnaire form. Methods: A total of 520 pregnant women were enrolled, after consenting each of them. Women were asked to fill the online questionnaire form give a clear answer to each item. This questionnaire defined three interconnected components of quality: structure, process, and outcomes. Deliveries outcomes were compared after the end of study. Primary outcome was assessment of the overall level quality of antenatal care service provision at Ain Shams University in comparison with other hospitals, private/public clinics and health offices. Secondary outcome was identification of the determinant factors for quality of antenatal care. Results: No differences between study groups regarding the three components of quality of ANC. However, our study revealed that other governmental and private healthcare settings were better than Ain Shams University Maternity Hospital regarding frequency of maternal weight and blood pressure measuring during ANC, fetal assessment using ultrasound, counseling about iron and calcium intake. Conclusion: Educational level (secondary and above) and attending regular ANC during pregnancy were significant factors associated with higher total ANC score. Caesarean section rate was higher among cases delivered at Ain Shams University Maternity Hospital that could be explained by Ain Shams Maternity University Hospital is a tertiary hospital and almost all cases delivered at it were complicated cases required urgent interventions.
Influence of Phenotypes on the Metabolic Syndrome of Women with Polycystic Ovary Syndrome over a Six-Year Follow-Up in Brazil

Background: We followed polycystic ovary syndrome (PCOS) women with metabolic syndrome (MS) over a six-year treatment period and evaluated the influence of PCOS phenotypes on MS and on the risk for type 2 diabetes mellitus (T2DM). Methods: This was an observational study of 457 PCOS women, whose demographic, clinical, hormonal, and metabolic data underwent analysis. The PCOS women were divided into four groups per NIH recommendations. Results: After a follow-up of a mean of six years (1–20 years), 310 patients were selected to assess the development of T2DM and MS. The clinical and biochemical parameters, along with the Rotterdam phenotypes, were evaluated. Data were analyzed using Student’s t- and the Pearson chi-square tests for data variation and group proportions, respectively. Additionally, multivariate analysis was applied to evaluate the effect of PCOS phenotypes on the risk for MS and T2DM. Patients of the four PCOS phenotypes did not differ in age, body mass index, total testosterone, insulin resistance, and dyslipidemia, but phenotype A patients showed the highest risk for T2DM. A decrease in androgen levels was not followed by an improved metabolic profile; instead, there was a significant increase in the number of T2DM cases. Conclusion: Phenotype A women are at the highest risk for type 2 diabetes mellitus.
A novel technique for torque ripple suppression in BLDC motor drive using switched capacitor based SEPIC converter

This article reports a strategy for suppressing commutation torque ripple has been proposed by modifying a SEPIC converter using switched capacitor. The torque ripple generated during the commutation period is one of the main disadvantages of a brushless DC (BLDC) motor. The cause for the torque ripple in brushless DC motor has been mathematically analyzed in this work. Henceforth, a modified switched-capacitor based DC-DC converter has been proposed for integration with BLDC drive. Moreover, a theoretical analysis of the relationship has been established between the duty ratio of the DC-DC converter with commutation time and torque ripple. A low cost and simple method to control the dc link voltage of BLDC drive has been proposed and a comparative analysis of the proposed converter with previously existing similar converters has been shown. This work aims at reducing ripple in electromagnetic torque of BLDC motor from the view point of duty ratio of the DC-DC converter and commutation time of the drive. The feasibility of the drive has been evaluated experimentally and through simulation. It has been observed that the integration of the proposed converter with BLDC drive help in torque ripple suppression to 16.5% as compared to BLDC drive without any DC-DC converter.
Influence of stormwater control measures on watershed hydrology and biogeochemical cycling

Bell, Colin D. Ph.D, Purdue University, August 2016. Influence of Stormwater Control Measures on Watershed Hydrology and Biogeochemical Cycling. Major Professor: Sara McMillan. Urban development replaces vegetation with impervious surfaces and natural drainage channels with pipe networks that quicken flow paths and alter hydrologic regimes. Additionally, the import of food, application of fertilizer to lawns and gardens, and heightened atmospheric deposition increases nutrient availability in urban landscapes. These excess nutrients are ultimately routed to streams through the pipe networks before it can be processed by the vegetation and microorganisms of the landscape. This combination of physical and chemical disturbances impacts stream ecosystems and degrades their ability to perform valuable services such as removal of nutrients, degradation of pollutants, and provision of recreational and aesthetic value. Stormwater control measures (SCMs) are a management strategy that can mitigate these impacts urbanization, ultimately preserving those valuable stream ecosystems. While the effects of urban development and individual SCMs on water quantity and quality have been well documented independently, studies examining the cumulative influence of SCMs on water quantity and nitrogen cycling throughout entire developed watersheds are lacking. First, this work addresses this gap in knowledge by
