Authors: Demarchi Sánchez Geydi Dahiana , Abadía Sánchez Janeth
Published: August 2023

Este artículo tiene como objetivo conocer la fundamentación epistemológica de las políticas públicas y el impacto en la sociedad. La pregunta central que aborda la investigación es: ¿Cuáles son los enfoques epistemológicos de las políticas públicas y cómo ha sido el impacto de cumplimiento en la sociedad? Como metodología se abordó el paradigma interpretativo comprensivo, tipo de investigación cualitativa y método hermenéutico para la verificación de la información y reconocimiento de similitudes y diferencias de los estudios consultados. Como conclusiones, se afirma que, si bien existen múltiples teorías que aportan al desarrollo conceptual y epistemológico de las políticas públicas, es necesario que se revise en la práctica los impactos sociales, porque las necesidades sociales persisten y se hacen más agudas día a día. Una posibilidad de mejora puede ser plantear políticas públicas a la luz de las necesidades reales de la población. También es vital para las trasformaciones que los colectivos sociales se organicen y participen en la identificación, agenda pública, formulación, puesta en marcha, seguimiento y control a las políticas públicas, participando durante todo el proceso.

Authors: Chen Xi , Zhang Ying , Fretts Amanda M. , Ali Tauqeer , Umans Jason G. , Devereux Richard B. , Lee Elisa T. , Cole Shelley A. , Zhao Yan D.
Published: August 2023

Background: Because of its convenience and robustness, the generalized estimating equations (GEE) method has been commonly used to fit marginal models of continuous outcomes in family studies. However, unbalanced family sizes and complex pedigree structures within each family may challenge the GEE method, which treats families as clusters with the same correlation structure. The appropriateness of using the GEE method to analyze continuous outcomes in family studies remains unclear. In this paper, we performed simulation studies to evaluate the performance of GEE in the analysis of family study data.

Methods: In simulation studies, we generated data from a linear mixed effects model with individual random effects. The random effects covariance matrix is specified as twice that of the pedigree matrix from the Strong Heart Family Study (SHFS) and other hypothetical pedigree structures. A Bayesian approach that utilizes the pedigree matrix was also conducted as a benchmark to compare with GEE methods with either independent or exchangeable correlation structures. Finally, analysis with a real data example was included.

Results: Our simulation results showed that GEE with independent correlation structure worked well for family data with continuous outcomes. Real data analysis revealed that all GEE and Bayesian approaches produced similar results.

Conclusion: GEE model performs well on continuous outcome in family studies, and it yields estimated coefficients similar to a Bayesian model, which takes genetic relationship into account. Overall, GEE is robust to misspecification of genetic relationships among family members.

Authors: Al-Bachir Mahfouz , Ahmad Husam
Published: August 2023

Background: Overweight and obesity has become a serious public health problem in the world. Changes in daily physical activity (PA) levels may help moderate the health risks of sedentary behavior (SB). The aim of the present study was to determine PA and SB by triaxial accelerometer (ActiGraph GTX3 GT3X+, ActiGraph, Pensacola, FL. 32502 USA) in Syrian adults that affected by age, marital, body mass index (BMI), education, and smoking status.Methods: We used cross-sectional baseline data from 97 participants of adults (18-60 years). Subjects wore an accelerometer for 7 consecutive days. Magnitude counts/minute was extracted to determine time in inactivity, in low-intensity, moderate, and vigorous-to-very-vigorous activity.Results: Higher age was associated with more time in all categories of PA (light, moderate vigorous MVPA with bouts, MVPA without bouts, and step per day), while higher BMI was related to less time in PA, overweight/obese subjects, on daily average, spent less, but not significantly, time standing and little more time spent in sitting than the normal weight groups. Participant comparing to non-smoking peoples tended to spent less time in PA; however, this synchronization was not considerable.Conclusion: Finally, our investigation demonstrated a positive synchronization between sedentary time and educational level. In this cohort of adults, most of men and women fulfilled the WHO recommendations. The levels of PA in 18–60-year-old adults are similar to previous data reported in adults.
Nitration and flow chemistry
Authors: Lu Jingyi , He Chennan
Published: August 2023

The paper introduced the principle of nitration reaction and flow chemistry, beginning with background information and the reaction mechanism of nitration. Then the correlation between nitration and flow chemistry is further explored by comparing the nitration reaction in conventional batch mode and under continuous flow. As the dangerous corrosive acids and strong exotherms make the reaction especially difficult to increase production scale, flow chemistry is utilized and proved to be a better alternative to the conventional production method to perform nitration. Using flow chemistry to scale up the exothermic and hazardous nitration reactions offer advantages including better yield, higher production rate, enhanced safety, etc.

Published: August 2023

Global energy demand is currently contributing to a severe problem of rising fuel prices for automobile users. One solution is to reduce the weight of the car body to improve fuel efficiency and reduce fuel costs. The choice of car body material can achieve this purpose. This paper will present the criteria such as stiffness, strength, and density to determine the suitability of substituting traditional materials, such as mild steel and carbon steel, with new materials High Strength Steel (HSS), aluminum alloys, and Long Fiber Thermoplastic (LFT). A literature review of the research is done to showcase the challenges traditional materials experience and how the development of these three new materials can overcome these challenges. Results from the case study show the feasibility of implementing these new materials in an automobile. More future research should be conducted to overcome the challenges and limitations posed by using these new materials, focusing on the low-cost replacement, manufacturing, and co-joining techniques of car body parts.

Published: August 2023

Due to the growing awareness of environmental protection, hybrid electric vehicles (HEV) have an increasing share in the automobile market. In order to offer customers HEV, which have long driven ranges, improvements must be made to enhance fuel efficiency. An energy Recovery System (ERS) is a newly developed technology aimed at fulfilling this target. This paper will compare multiple ERS that use exhaust gases as a source of energy. A clear understanding of each technology can be established by first reviewing and summarizing the advantages and challenges of each ERS. After that, a comparison between different technologies will be conducted to find the optimal ERS for compact HEV. Results show that integrated ETC is a more suitable method of energy recovery for the exhaust system in HEV based on the criterion that the combustion engines those energy recovery technologies apply to are the same.

Neste estudo, buscou-se identificar nas fontes da literatura científica as narrativas indígenas relacionadas ao suicídio. A presente revisão bibliográfica abrange o período de 2012 a 2021, utilizando bases de dados BVS, MEDLINE e SCIELO. Foram selecionados cinco estudos para análise, todos eles publicados em periódicos nacionais. Os resultados apontaram dois eixos principais de discussão sobre o suicídio indígena: o crescente desafio como questão de saúde pública e a abordagem dos aspectos culturais. Dentre as possíveis causas associadas à ideação suicida entre a população indígena brasileira, destacam-se fatores como doença mental prévia, circunstâncias afetivas, sociais, econômicas, bem como aspectos da vida pessoal, social e até ritualística. Conclui-se que o tema do suicídio indígena é complexo, envolvendo diversas abordagens interpretativas, as quais não podem ser simplificadas ou reduzidas. Não existe uma causa única para o aumento de suicídios entre os índios brasileiros, mas sim um conjunto multifatorial de possíveis causas, incluindo aspectos biológicos, psicológicos, políticos, econômicos, sociais, antropológicos e culturais.

Objective: Determine the effects of nursery pig weaning weight (WW) and first week postweaning growth rate (ADG7) on average daily gain (ADG), final weight, removals, and mortality under field conditions. Materials and methods: In this 42-day study, 1602 pigs (mean [SD] weight: 5.42 [0.9] kg) were weaned at 19 to 21 days of age. Four successive batches of weaned pigs were moved into the same nursery room. Within each batch, pigs were allotted by WW to have approximately one-third of each class (LightWW, MediumWW, and HeavyWW) in all pens. On day 7, pigs were individually weighed and designated according to their ADG7 into four classes within their batch: NegativeADG7, LowADG7, MediumADG7, and HighADG7. An equation was developed and validated to quantify the association between WW and ADG7 with ADG. Results: Weaning weight had no effect on ADG7 (P = .42), but increasing WW and ADG7 increased (P < .001) ADG and final weight at 42 days. Pig removal was reduced if pigs had heavy WW or gained weight in the first week after weaning (≤ 3.2%) compared to pigs that lost weight during the first week in the LightWW (20.9%) or MediumWW (10.3%) categories. Overall mortality was 1.1% with no effects of WW, ADG7, or its interaction (P > .54). The equation generated indicated that WW and ADG7 together had moderate accuracy (R² = 0.54; P < .001) to predict ADG. Implication: The WW and ADG7 are not correlated, but they affect and partially predict the overall nursery performance.
Potential to export fresh pork in the event of an African swine fever outbreak in the United States
Authors: Roth James
Published: August 2023

An African swine fever (ASF) outbreak in the United States would result in the loss of fresh pork exports and a decrease in pig price. The World Organisation for Animal Health (OIE) Terrestrial Animal Health Code provides a potential opportunity for packers, working with swine production systems and the US Department of Agriculture (USDA), to maintain a significant portion of exports during an ASF outbreak through a combination of producer biosecurity and surveillance, packers only accepting pigs from production systems that meet specific requirements, and the USDA developing veterinary certificates for export stating the pork shipment meets the OIE requirements.
Relationship between weekly porcine reproductive and respiratory syndrome virus exposure in breeding herds and subsequent viral shedding and mortality in the nursery

Objective: Describe the relationship of weekly breeding herd status based on processing fluid (PF) testing for porcine reproductive and respiratory syndrome virus (PRRSV) RNA by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) on subsequent viral shedding and cumulative mortality during the nursery phase. Materials and methods: Weekly cohorts (n = 121) of newborn piglets were classified into PRRSV exposure groups according to PRRSV detection in PF: low (quantification cycles [Cq] ≤ 27), medium (27 < Cq ≤ 34), high (34 < Cq ≤ 37), and negative (Cq > 37). At 6 weeks of age, oral fluids (OF) were collected from a subset of 41 cohorts, tested by qRT-PCR, and results used to classify the nursery shedding status into the same aforementioned categories. Cumulative nursery mortality was recorded for all 121 cohorts and compared between the different PRRSV exposure groups. Test agreement was assessed between PF and OF results of 41 cohorts. Moreover, the effect of 4:1 OF pooling on the probability of testing qRT-PCR-positive was evaluated. Results: The nursery mortality for low Cq cohorts was 3.40 percentage points (range, 3.28-3.99) higher than other exposure groups. Overall, Cq values were higher in PF than in OF samples, and fair agreement (κ = 0.2398) between PF and OF was encountered. Compared to individual samples, 4:1 OF pooling resulted in 100% specificity and 76.92% sensitivity. Implications: Weekly PF testing for PRRSV allowed for exposure group classification for each pig batch produced, which was a good predictor of subsequent cumulative nursery mortality.
Clinical hyperestrogenism associated with unintentional phytoestrogenic soybean intake
Authors: Timmer Josh , Holden Damian , Scott Peter , McOrist Steven
Published: August 2023

This case study characterizes breeding performance related to unintentional dietary intake of phytoestrogenic compounds. Breeder farms A (affected) and B (unaffected) were under single management and supplied by two unconnected feed mills. Breeding parameters were recorded over 2 years and feed analyzed for mycotoxins and isoflavonoids. Farm B had consistently better breeding performance. Clinical signs of hyperestrogenism (vulval tumefaction, mammary gland dysfunction, and delayed estrus) were evident in 5% to 10% of breeding females on farm A. Mycotoxin concentrations were negligible, but phytoestrogenic isoflavonoid concentrations associated with one source of soybean meal were above 55,000 µg/kg on farm A.

A standardized system for classifying the porcine reproductive and respiratory syndrome virus (PRRSV) status of swine herds is necessary for communication between veterinarians and producers. The 2011 classification system has been widely adopted by producers and veterinarians worldwide. In 2018, a working group met to revisit the system and make recommendations for changes. The most significant modification was to the classification of positive unstable and positive stable breeding herds. Recommended diagnostic protocols for promotion of herds to each status were modified and recommended diagnostic protocols to maintain a status were added. The growing pig classification for PRRSV was also modified.

A standardized system for classifying the Mycoplasma hyopneumoniae status of swine breeding herds was developed by defining a set of diagnostic guidelines to determine the exposure and shedding status of herds. The classification is based on epidemiological and ecological features of M hyopneumoniae and reflects current field control and elimination practices. The classification was developed by a working group composed of representatives from academia, industry, swine practitioners, American Association of Swine Veterinarians (AASV), and the National Pork Board, and approved by the AASV Board of Directors on October 2, 2019. Clear and concise terminology will facilitate communication across all stakeholders.
