Preparation to teach agricultural mechanics: a qualitative case study of expert agricultural science and technology teachers in Texas

Preparation to Teach Agricultural Mechanics: A Qualitative Case Study of Expert Agricultural Science and Technology Teachers in Texas. (December 2005) Richard Kirby Ford, B.S., Texas A&M University, M.S., Texas A&I University Co-Chairs of Advisory Committee: Dr. Glen C. Shinn Dr. David E. Lawver Since federal legislation in 1917 and the widespread program growth in the 1930s, agricultural mechanics has been a major part of the high school agricultural science and technology curriculum. Local programs integrated individual problem -solving, practical applications of mathematics and technical science skills in to the curriculum. However, recent financial constraints and a perceived lack of interest have led to reductions in course offerings in agricultural mechanics in some universities that are responsible for the maintenance and future of the disciplinary area. These curricular issues gave rise to a research problem examining the perspectives of successful agricultural science and technology teachers of agricultural mechanics and the education and experiences that were associated with their success. This study used qualitative measures to identify factors that enabled certain agricultural science and technology teachers who were more noted in teaching of agricultural mechanics to be more successful than their peers. It examined factors that motivated teachers to excel and examined the influences that determined what portions of the curriculum were included or deleted. Finally, this study focused on the
Acoustic Wave Propagation in Low Mach Flow Pipe

Flow induced vibrations and resulting sound are observed in many situations, with applications ranging from music and human sciences to process and aerospace industry. In the case of flow through corrugated pipes extremely strong acoustic field can be produced, which in extreme cases can result in structural and component damage. In the present paper we analyze the physical phenomena resulting in sound production in corrugated pipes. The flow over single cavities is computed and it is shown that a given corrugation geometry can cause self sustained pressure oscillations caused by interactions between vortices shed from neighboring corrugation cavities. In a larger computation the flow and resulting acoustics in a corrugated, 0.614 m long, pipe is analyzed. Now, a large scale acoustic field is captured, leading to formation of standing sound waves in the pipe. The simulations of the singing frequencies compared well to measured frequencies versus flow velocities. Based on the mechanisms revealed through this analyzes a general feedback loop mechanism for flow induced sound in corrugated pipes is proposed.
ENHANCING AN ATL TRANSFORMATION WITH TRACEABILITY

Model transformation is widely recognized as a key issue in model engineering approaches. In previous work, we have developed an ATL transformation that implements a strategy to obtain a set of Raise Specification Language (RSL) modules from Feature Models (FM). In this paper, we present an improvement to this strategy by defining another complementary and independent model, allowing the incorporation of traceability information to the original transformation. The proposed mechanism allows capturing and representing the relationships created by the application of the transformation rules.
Prevalence of Premenstrual Dysphoric Disorder among Female Students of a Medical College in Nepal: A Descriptive Cross-sectional Study

ABSTRACT Introduction: Premenstrual dysphoric disorder is a severe form of premenstrual syndrome that impairs quality of life and carries an increased risk of suicidal attempts. Hormonal changes may underlie these symptoms. The present study was conducted to find out the prevalence of premenstrual dysphoric disorder among female students of a medical college in Nepal. Methods: This descriptive cross-sectional study was conducted among 266 healthy young females in a medical college of Nepal from 21st June 2021 to 31st August 2021 with approval from the Institutional Review Committee 51/2021. Convenience sampling was done. Self-rated questionnaire of premenstrual symptoms screening tool was used to evaluate premenstrual dysphoric disorder. The Premenstrual Symptoms Screening Tool reflects and 'translates' categorical Diagnostic and Statistical Manual of Mental Disorders-IV criteria into a rating scale with degrees of severity. Data were analyzed using the Statistical Package for Social Sciences version 16. Point estimate at 95% confidence interval was calculated along with frequency and proportion for the binary data. Results: Out of 266 female students, we found that the prevalence of premenstrual dysphoric disorder was 10 (3.8%) (1.50-6.10 at 95% Confidence Interval). Conclusions: The prevalence of premenstrual dysphoric disorder in our study was found to be higher when compared to other similar studies.
Analysis of Online Social Behavior of Whatsapp Users

Whatsapp is the most popular social media platform that allows users to interact with each other by sending texts, emoji, images, voice notes, videos etc. Whatsapp users spend hours chatting with each other exchanging information and also sharing intimate feelings that are often touted as deep meaningful conversations. This paper focuses on the study of online social behavior of Whatsapp users which are primarily students in the age group of 18-25 years. 300Whatsapp chats from 30 university students have been collected and scrutinized to determine their online behavior in terms of being expressive on Whatsapp or not and also identifying their general mood on Whatsapp based on their emotional manifestation in the chats. This analysis can be of compelling interest to various psychological researchers, social media influencers and counselors.
Context-aware knowledge selection and reliable model recommendation with ACCORDION

New discoveries and knowledge are summarized in thousands of published papers per year per scientific domain, making it incomprehensible for scientists to account for all available knowledge relevant for their studies. In this paper, we present ACCORDION (ACCelerating and Optimizing model RecommenDatIONs), a novel methodology and an expert system that retrieves and selects relevant knowledge from literature and databases to recommend models with correct structure and accurate behavior, enabling mechanistic explanations and predictions, and advancing understanding. ACCORDION introduces an approach that integrates knowledge retrieval, graph algorithms, clustering, simulation, and formal analysis. Here, we focus on biological systems, although the proposed methodology is applicable in other domains. We used ACCORDION in nine benchmark case studies and compared its performance with other previously published tools. We show that ACCORDION is: comprehensive, retrieving relevant knowledge from a range of literature sources; very effective, reducing the error of the initial baseline model by more than 80%, recommending models that closely recapitulate desired behavior, and outperforming previously published tools; selective, recommending only the most relevant, context-specific, and useful subset (15-20%) of candidate knowledge in literature; diverse, accounting for several distinct criteria to recommend more than one solution, thus enabling alternative explanations or intervention directions.
Diagnostic accuracy of point‐of‐care ultrasound compared to standard‐of‐care methods for endotracheal tube placement in neonates

Point‐of‐care ultrasound (POCUS) is a valuable tool to determine endotracheal tube (ETT) placement; however, few studies have compared it with standard confirmation methods. We evaluated the diagnostic accuracy of POCUS and time‐to‐interpretation for correct identification of tracheal versus esophageal intubations compared to a composite of standard‐of‐care methods in neonates.

The results of statistical analysis indicate that ISO 9000 implementation significantly improves various quality management practices and quality performance. This study contributes to the quality management literature by highlighting the significant impact of ISO 9000 on the performance of the Vietnamese companies. In addition, the results of this study provide meaningful and practical insight into quality management practices in the companies.
Quantitative genetic aspects of carcass composition, assessed by X-ray computer tomography, and meat quality traits in sheep

The overall aim of this thesis is to explore quantitative genetic aspects of carcass and meat quality traits in sheep and consider the utilization of such information in breeding programmes. The focus is to breed for improved lamb meat quality, as there is a downward trend in lamb consumption over the past years and selection objectives in sheep breeding are changing, as consumers require leaner meat, less fat and consistent quality. Therefore, traits determining product quality are carcass composition and meat quality. A number of selection experiments have reported rapid changes in carcass composition by selecting on live animal estimates. On the other hand, meat quality traits pose particular problems for improvement, as direct measurements require the destruction of the animal. Muscle quality is considered to be difficult, if not impossible, to measure in the live animal and is very expensive to measure completely in samples from the carcass. Hence, this thesis investigated the use of in vivo composition traits to predict meat quality. Additionally, it investigated potential opportunities for genetically improving meat and carcass quality by using in vivo predictor traits and quantitative trait loci (QTL). Data for carcass composition and meat quality was collected over four years from a Blackface population. Within this population, a double backcrossed design created nine half-sib families, for QTL detection. Carcass composition was measured using in vivo computed tomography (CT) on equal number of males and females per year. Cross-sectional scans were taken at the ischium (ISC), the 5th lumbar vertebrae (LV5) and the 8th thoracic vertebrae (TV8), and from each scan image the areas and image densities were obtained for the fat, muscle and bone components of the carcass. Meat quality measurements taken on male lambs, that had previously been CT scanned, included (i) initial and final pH of the meat, (ii) toughness, (iii) colour, (iv) intramuscular fatty acid composition, (v) water, marbling fat and protein content of the meat, and (vi) taste panel assessment of the cooked meat.
Seismic Fragility Functions for Sewerage Pipelines

Fragility functions (or fragility curves when presented graphically) are a well established tool to assess seismic risk to infrastructures. Given a sustained level of ground motion intensity, seismic fragility functions of sewerage pipelines are used for predicting earthquake-induced physical damage to sewer pipes. However, existing fragility functions of sewerage pipelines refer to a limited number of pipe types and material categories. Therefore practitioners often draw upon fragility functions specifically defined for potable-water pressure pipelines available in the international literature, for foreseeing earthquake-induced failures on sewerage gravity and pressure pipelines. The discrepancies between existing fragility curves and the observed physical damage data collected after the Canterbury (NZ) Earthquake sequence in 2010-2011, evidence that the fragility functions defined for potable-water pipelines tend to underestimate the physical damage to sewerage gravity pipelines. This paper proposes fragility functions for sewer gravity and pressure pipelines, categorized by pipe materials and liquefaction zones. The proposed fragility functions are developed using maximum likelihood estimation by correlating peak ground velocity with damage ratio (defined as number of faults per km) for sewer gravity pipes and with repair rate, defined as number of repairs per km for sewerage pressurized pipelines.
Assessing Some Potential Environmental Impacts from Agricultural Anticoagulant Uses

This study was designed to give us a better understanding of the relationship between agricultural anticoagulant ro denticide uses and related occurrence of these materials in raptor tissues. The project utilized data from raptor carcasses collected, both in urban San Diego County and in largely agricultural Fresno, Kern, and Madera Counties, as part of the public health surveillance programs of the County Veterinarian(s) and/or Departments of Environmental Health. Most raptors contained detectible levels of secondgeneration anticoagulants, which are registered only for commensal rodent control in and around structures; very few contained firstgeneration anticoagulants, which are the only anticoagulants registered for use in agricultural production in California. This suggests that secondary hazards to raptors and other wildlife from anticoagulants stems primarily from retail sale of commensal rodent baits, particularly in residential areas, and not from anticoagulant rodenticide uses in agricultural regions.
Research on several indicators in the twelfth five-year program for work safety

Occupational injury indicators play important roles in work safety administration and macro decision-making.To further improve the system of statistical indicators of occupational injury,the scientific and practicability as well as problems about several occupational indicators in the Twelfth Five-year program for work safety were studied.Based on preliminary calculation,theoretical analysis and comparison of main occupational injury indicators at home and abroad,we gave a few suggestions,namely adjusting or deleting the indicator fatal rate per one hundred million GDP,increasing non-fatal accident statistic indicators to better representative of the total occupational injuries,applying indicators of major accidents appropriately and increasing accuracy of the indicator fatal numbers per 100000 workers.We advised that we should strengthen research on occupational injury indicators so as to consistent with international standards of occupational injury statistical indicators soon as possible,and to make occupational injury data of China return in the Yearbook of International Labor Statistics.

The role of rice SOG1 and SOG1-like in DNA damage response

Higher plants are constantly exposed to environmental stresses, and therefore complicated defense systems, including DNA damage response (DDR) and DNA repair systems, have developed to protect plant cells. In Arabidopsis, the transcription factor SUPPRESSOR OF GAMMA RESPONSE 1 (SOG1) has been reported to play a key role in DDR. Here, we focus on DDR in rice—thought to be a simpler system compared with Arabidopsis due to lack of induction of endocycle even under DNA damage stress. Rice SOG1 (OsSOG1) and SOG1-like (OsSGL) were identified as putative AtSOG1 orthologs with complete or partial conservation of the serine-glutamine (SQ) motifs involved in activation via phosphorylation. In addition to OsSOG1- or OsSGL-knockout mutants, OsSOG1 non-phosphorylatable mutants (OsSOG1-7A) were generated by homologous recombination-mediated gene targeting. Based on DNA damage susceptibility and transcriptome analysis using these mutants, we demonstrated that OsSOG1, but not OsSGL, plays a central role in the DDR and DNA repair. OsSOG1 regulated target genes via CTT (N)7 AAG motifs reported previously as AtSOG1 recognition sites. The loss of transcription activities and DNA damage tolerance of OsSOG1-7A was not complete compared with OsSOG1-knockout mutants, raising the possibility that another phosphorylation site might be involved in the activation of OsSOG1. Furthermore, our findings have highlighted differences in SOG1-mediated DDR between rice and Arabidopsis, especially regarding induction of cell-cycle arrest and endocycle arrest, revealing rice-specific DDR mechanisms. One sentence summary Rice transcription factor SUPPRESSOR OF GAMMA RESPONSE 1 controls DNA damage response and DNA repair through activation via phosphorylation and the direct regulation of expression of numerous genes.
Emergency Control Based on the Sensitivity Analysis of Transient Kinetic Energy of Dynamic Saddle Point

It is one of the difficulties of power system analysis and control to determine the emergency control strategy of the AC/DC transmission systems with the generator tripping,load shedding and DC power lifting,taken into account.An emergency control method based on the sensitivity analysis of transient kinetic energy of the dynamic saddle point(DSP)is proposed.The searching direction is to be selected by the improvements of DSP transient kinetic energy with the control measures and all units’ weighted participation factor indices,so as to track the unstable mode and participation factor variations,and search for the coordinative emergency control strategy.The analysis results of the Central China-North ChinaEast China interconnected power grid and the South China power grid show that the proposed approach is practical and effective.
Constructing an Adapted Cascade of Diabetes Care Using Inpatient Admissions Data: Cross-sectional Study

Background The diabetes mellitus cascade of care has been constructed to evaluate diabetes care at a population level by determining the percentage of individuals diagnosed and linked to care as well as their reported glycemic control. Objective We sought to adapt the cascade of care to an inpatient-only setting using the electronic health record (EHR) data of 81,633 patients with type 2 diabetes. Methods In this adaptation, linkage to care was defined as prescription of diabetes medications within 3 months of discharge, and control was defined as hemoglobin A1c (HbA1c) below individual target levels, as these are the most reliably captured items in the inpatient setting. We applied the cascade model to assess differences in demographics and percent loss at each stage of the cascade; we then conducted two-sample chi-square equality of proportions tests for each demographic. Based on findings in the previous literature, we hypothesized that women, Black patients, younger patients (<45 years old), uninsured patients, and patients living in an economically deprived area called the Promise Zone would be disproportionately unlinked and uncontrolled. We also predicted that patients who received inpatient glycemic care would be more likely to reach glycemic control. Results We found that out of 81,633 patients, 28,716 (35.2%) were linked to care via medication prescription. Women and younger patients were slightly less likely to be linked to care than their male and older counterparts, while Black patients (n=19,141, 23.4% of diagnosed population vs n=6741, 23.5% of the linked population) were as proportionately part of the linked population as White patients (n=58,291, 71.4% of diagnosed population vs n=20,402, 71.0% of the linked population). Those living in underserved communities (ie, the Promise Zone) and uninsured patients were slightly overrepresented (n=6789, 8.3% of diagnosed population vs n=2773, 9.7% of the linked population) in the linked population as compared to patients living in wealthier zip codes and those who were insured. Similar patterns were observed among those more likely to reach glycemic control via HbA1c. However, conclusions are limited by the relatively large amount of missing glycemic data. Conclusions We conclude that inpatient EHR data do not adequately capture the care cascade as defined in the outpatient setting. In particular, missing data in this setting may preclude assessment of glycemic control. Future work should integrate inpatient and outpatient data sources to complete the picture of diabetes care.
Secondary Immunodeficiency Frequency in Patients with Chronic Lymphocytic Leukemia: The Relationship with Stage and Treatment

Background: Chronic lymphocytic leukemia (CLL) is one of the most common hematological malignancies. In patients with CLL, serum immunoglobulin levels decrease over time due to both the disease itself and the chemo-immunotherapeutic agents used. It was aimed to reveal the relationship between hypogammaglobulinemia and disease stage, and chemo-immunotherapies. Materials and Methods: Data were obtained by retrospectively examining 74 patients who were followed-up between 2008-2019. The relationship between all parameters (demographic characteristics, RAI stages or therapy subtypes) and serum IgG levels was analyzed. Results: Thirty-two of 74 patients received a therapy. Twenty-two patients were on combined therapy with rituximab or only rituximab and 10 were treated with chemotherapeutic agents only. The frequency of hypogammaglobulinemia was 5.4% at the diagnosis, this rate was 55% in patients receiving a therapy. Hypogammaglobulinemia was higher in advanced stages. In patients with rituximab, higher levels of IgG decrease were observed. Conclusion: Serum IgG level was significantly lower in patients with advanced-stage, received chemotherapy, especially rituximab. In addition to basal IgG, immunoglobulin levels should be checked during treatment, and follow-up period. Early replacement intravenous immunoglobulins will be important to reduce severe infection attacks due to secondary immunodeficiency.
