Performance and carcass characteristics of grower pigs fed enzyme-supplemented dried cassava peel – maize cob composite meal
No full textA 90-day trial was carried out to evaluate the performance and carcass characteristics of grower pigs fed enzyme-supplemented dried cassava peel-maize cob composite meal (CP-MC). A total of 36 crossbreed male grower pigs (Large white) of about 16 weeks old with an initial body weight of 20.31 ± 0.61 kg-1 were randomly allotted into four groups of nine animals per treatment. Each treatment was further divided into three replicates consisting of three pigs in a completely randomized design. Pigs in treatment 1 were fed 0% CP-MC while CP-MC was used to replace maize at 40% (T2), 50% (T3), and 60% (T4). Diet was adequate in all nutrients, and clean water and feed were offered ad libitum. Results on growth performance showed that average daily weight gain was higher in T4 (0.34 kg) and T3 (0.33 kg), intermediate in T2 (0.26 kg), and lower in T1 (0.23 kg) (p < 0.05). Similarly, the best feed conversion ratio was found among pigs in T4 followed by T3, T2, and T1 (p < 0.05). Conversely, average daily feed intake was not influenced by the treatments (p > 0.05). Dressing percentages varied from 61.60-71.94% were significantly (p < 0.05) different among the treatments. Weights of the head, belly, limbs, back fat thickness, kidney liver, lungs, and spleen were significantly (p < 0.05) different among the treatments. In conclusion, the replacement of maize with CP-MC at 60% improved the weight of pigs without compromising the performance of animals
Fossil hailstone imprints in Mesoproterozoic (1.7 Gyr) quartzite of the Tombador Formation (Chapada Diamantina Group), Brazil
Get PDFFossil pockmarks, 2.5-4 cm in diameter, 3-8 mm deep, with raised, asymmetrical borders are preserved in Mesoproterozoic quartzite representing fluvial and eolic lithofacies of the Tombador Formation (Chapada Diamantina Group) deposited 1.7 billion years ago in what is now northeastern Brazil. Indentations created by projecting 2-4 cm diameter ice pellets into moist beach sand were of the same type - with raised, asymmetrical borders and equivalent diameters and depths – strongly supporting the hypothesis that the fossil features represent impressions of paleohailstone impacts. These well-defined and well-preserved paleohailstone impressions represent the oldest known features of their type in the world, and the first records from South America

Interfaces das estomias intestinais nos ciclos de vida
Get PDFThe term Quality of Life, despite not having a consensual definition, is based on the individual perception of a complete physical, mental and social well-being that permeates a dynamic, broad, subjective and polysemic concept. The individual with a stoma needs post-operative care and help with day-to-day tasks, in addition to self-care and social interactions to remain psychologically and physically healthy, as there are numerous changes in habits and routine of life. From this perspective, the following question arises for the study: What are the impacts of the ostomy in the different life cycles? The objective of this research is to analyze the repercussion of making an intestinal stoma in patients at different stages of life, contributing to the updating of knowledge in multiple assertions. This is a descriptive, qualitative study of the reflective analysis type, based on a literature review on the “interfaces of intestinal ostomies in life cycles”. For that, a narrative review was carried out. Narrative review studies are publications with the purpose of describing and discussing the state of the art of a given subject. The results obtained through the literature review allow us to say that the quality of life of people with a stoma is a fundamental aspect for their physical, emotional and social health. In each life cycle, people with a stoma face specific challenges that affect their routine and their way of relating in society. Finally, it is important to highlight that the quality of life of people with ostomies is not just a matter of choosing the ideal device, but also access to adequate health care and public policies that guarantee access to quality devices and materials. It is important that these individuals are always monitored by a multidisciplinary team, along with a family support network providing self-care and maintenance of their self-image.O termo Qualidade de Vida apesar de não possuir uma definição consensual, se baseia na percepção individual de um completo bem-estar físico, mental e social que permeia um conceito dinâmico, amplo, subjetivo e polissêmico. O indivíduo estomizado necessita de cuidados pós-operatórios e ajuda nas tarefas do dia a dia, além do autocuidado e interações sociais para se manter psicologicamente e fisicamente saudável já que são inúmeras mudanças nos hábitos e rotina de vida. A partir dessa perspectiva, surge o seguinte questionamento para o estudo: Quais os impactos da estomia nos diferentes ciclos de vida? O objetivo dessa pesquisa foi analisar a repercussão da confecção de um estoma intestinal de pacientes em diferentes estágios da vida, colaborando para a atualização do conhecimento em múltiplas asserções.

Analysis of Multi-Threading and Cache Memory Latency Masking on Processor Performance Using Thread Synchronization Technique
Get PDFMultithreading is a process in which a single processor executes multiple threads concurrently. This enables the processor to divide tasks into separate threads and run them simultaneously, thereby increasing the utilization of available system resources and enhancing performance. When multiple threads share an object and one or more of them modify it, unpredictable outcomes may occur. Threads that exhibit poor locality of memory reference, such as database applications, often experience delays while waiting for a response from the memory hierarchy. This observation suggests how to better manage pipeline contention. To assess the impact of memory latency on processor performance, a dual-core MT machine with four thread contexts per core is utilized. These specific benchmarks are chosen to allow the workload to include programs with both favorable and unfavorable cache locality. To eliminate the issue of wasting the wake-up signals, this work proposes an approach that involves storing all the wake-up calls. It asserts the wake-up calls to the consumer and the producer can store the wake-up call in a variable. An assigned value in working system (or kernel) storage that each process can check is a semaphore. Semaphore is a variable that reads, and update operations automatically in bit mode. It cannot be actualized in client mode since a race condition may persistently develop when two or more processors endeavor to induce to the variable at the same time.
This study includes code to measure the time taken to execute both functions and plot the graph. It should be noted that sending multiple requests to a website simultaneously could trigger a flag, ultimately blocking access to the data. This necessitates some computation on the collected statistics. The execution time is reduced to one third when using threads compared to executing the functions sequentially. This exemplifies the power of multithreading
Biochemical interaction of twenty steroid derivatives with ribosomal protein kinase 4 S6 (RSK-4) surface using a theoretical model
Get PDFSeveral genetic expressions have been involved in the development of cancer such as the expression of a ribosomal kinase S6 P90 (RSK-4). It is important to mention that some compounds such as LJH685, 2073047-06-8, and SL0101 can act as RSK-4 inhibitors; however, its interaction with the surface of RSK-4 is very confusing. The aim of this research was to evaluate the interaction of twenty-nine steroid derivatives (1 to 29) with of RSK-4 surface using 6rv2 protein, LJH685, 2073047-06-8 and SL0101 as theoretical tools in the Dockingserver program. The results showed differences in the aminoacid residues involved in the interaction of steroid derivatives with 6rv2 protein surface compared with LJH685, 2073047-06-8 and SL0101. Besides, the inhibition constant for steroid derivatives 1, 12, 14, 19 and 22 was lower compared to 2073047-06-8 drug. In conclusion, the steroid derivatives 1, 12, 14, 19 and 22 could be a good alternative as RSK-4 inhibitors to decrease cancer cells growth
Entrepreneurial psychosocial profile of university women in the State of Mexico, Mexico
Get PDFThe present empirical research is a descriptive and correlational study from the psychosocial perspective, the objective is to analyze the relationship between the intention to undertake and variables such as family with businesses, work intention, initial motivations, personality traits, individualistic, collectivist and mixed values, support for self-employment in the educational center, difficulty to create a company and pereception of the entrepreneur, to integrate an entrepreneurial psychosocial profile of university women from Higher Education Schools in the State of Mexico, Mexico. The sample under study was obtained with the participation of 297 women. Among the main findings is the existence of weak positive relationships in most of the variables studied about entrepreneurship. The risk-taking personality trait is less commonly observed. The most important human values observed are individualistic self-direction, collectivist benevolence, and universalism as mixed value, in this sense, entrepreneurship in commercial businesses and social entrepreneurship are alternatives for the intention of entrepreneurship in university women. Regarding the support from the Educational Center, the correlation was little or non-existent, however, recovering the importance of promoting visits to companies to receive advice or seminars, university women also state that self-employment is stimulated, but the knowledge offered has a low average trend. Another finding is perceived difficulties, which are external such as funding, grants, bureaucracy and advice. Finally, the perception of the entrepreneur is positive
Fatores socioeconômicos e culturais da pessoa com estomia intestinal
No full textStoma also known as “ostomy”, consists of an artificial opening surgically created to divert the flow of effluents to the external environment. This condition affects the life of the affected individuals and requires care when resuming activities to avoid complications related to the surgery. The rate of intestinal stoma has a higher recurrence rate in men and is often associated with urban violence, car accidents, associated with the use of licit and illicit drugs, lower demand and use of Primary Health Care services for preventive measures, seeking medical care only when there is worsening of diseases. This is a descriptive, qualitative study of the reflective analysis type, a narrative review. Thus, we selected and analyzed articles published in the last five years, in Portuguese and that approached the theme, in order to acquire more depth and approximation with the object of study to subsidize the reflections. Seven categories were elaborated, being them, respectively: Everyday life of the person with intestinal stoma; Family income of the person with intestinal stoma; Nutritional interfaces for people with intestinal stomas; Hydric ingestion of the person with intestinal stoma; Smoking, stylism and use of illicit drugs related to the person with intestinal stoma; Leisure and social life of the person with intestinal stoma, and Execution of physical activities by the person with intestinal stoma. thus, the objective of the study is the socioeconomic and cultural factors of the person with intestinal stomy.A estomia, também conhecida como “ostomia”, consiste em uma abertura artificial criada cirurgicamente para desviar o fluxo de efluentes para o meio externo. Essa condição afeta a vida dos indivíduos acometidos e requer cuidados na retomada das atividades para evitar complicações relacionadas à cirurgia. O índice de estoma intestinal tem maior taxa de recorrência em homens e está frequentemente associado à violência urbana, acidentes automobilísticos, associados ao uso de drogas lícitas e ilícitas, menor procura e utilização dos serviços de Atenção Primária à Saúde para as medidas preventivas, buscando atendimento médico somente quando ocorre agravamento das doenças. Trata-se de um estudo descritivo, qualitativo do tipo análise reflexiva, uma revisão narrativa. Desta forma, foram selecionados e analisados artigos publicados nos últimos cincos anos, nos idiomas português e que abordassem o tema, no intuito de adquirir maior aprofundamento e aproximação com o objeto de estudo para subsidiar as reflexões. Foram elaboradas 7 categorias, sendo elas, respectivamente: Cotidiano da pessoa com estomia intestinal; Renda familiar de pessoas com estomia intestinal; Interfaces nutricionais para pessoas com estomias intestinais; Ingesta hídrica da pessoa com estomia intestinal; Tabagismo, estilismo e uso de drogas ilícitas relacionados a pessoa com estomia intestinal; Lazer e vida social da pessoa com estomia intestinal; e Execução de atividades físicas pela pessoa com estomia intestinal.

Effect of plant spacing on pigeonpea grain yield in Northern Uganda
No full textThe aim of crop production is to achieve the highest possible yield per unit area. One way of increasing productivity per unit area is through plant spacing optimization. The effect of plant spacing (90 cm x 60 cm, 150 cm x 120 cm and 150 cm x 180 cm) on yield of three pigeonpea genotypes (KAT 60/8, ICEAP 00540 and ICEAP 00554) was investigated on-station in a small-plot field experiments in 2018. Significant differences were recorded in grain yield of all the three genotypes. The highest yield for all the three genotypes was recorded for row spacing of 90 cm and inter plant spacing of 60 cm, and the lowest for row spacing of 150 cm and inter plant spacing of 180 cm. Plant spacing effect on other yield parameters (number of pods per plant and 100 seed weight) were not significant. Similar effects were recorded for plant growth parameters (plant height and number of primary branches). Thus, it can be concluded that row spacing of 90 cm and interplant spacing of 60cm is appropriate for pigeonpea grain production in Uganda
