RESUMO: A silagem é uma importante tecnologia utilizada pelos produtores rurais e indispensável dentro dos sistemas de produção intensivos ou não. A silagem resulta da ação de microrganismos que fermentam o material orgânico, resultando em um alimento rico e nutritivo para o gado leiteiro. Entretanto, estudos demonstrando a viabilidade do processo em pequenas propriedades são escassos. Neste sentido o trabalho objetivou avaliar a viabilidade da cultura de milho utilizada para a produção de silagem em uma propriedade leiteira familiar, bem como, identificar método para maximizar o retorno financeiro à propriedade. Os resultados demonstraram que um melhor planejamento na aquisição dos insumos e a utilização de plantio de cobertura, podem reduzir os custos e a quantidade dos insumos utilizados. Frente ao custo gerado pela produção do milho ensilado, se o produtor vender o grão quando o valor da saca for superior a R$ 75,50 e, comprar o alimento de terceiros, seu lucro líquido será maximizado em 5%.

ECONOMIC FEASIBILITY OF THE CORN CROP TO SILAGE IN A DAIRY CATTLE PROPERTY

ABSTRACT: Silage is an important technology used by rural producers and indispensable in production systems intensive or not. The silage results from the action microorganisms that fermented organic matter, resulting in a rich and nutritious food for dairy cattle. However, studies demonstrating the viability of this process on small properties are scarce. In this sense, this work aimed to evaluate the viability of corn crops used for the production of silage on a family dairy farm, as well to identify a method to maximize financial return to the property. The results showed that good planning in the acquisition of inputs and use of cover crops can reduce the costs and quantity of inputs used. In view of the cost generated by the production of corn silage, if the producer sells the production when the value of the bag exceeds R$ 75.50 and buy the silage from third parties, his net profit will be maximized by 5%.

Published: March 2022

: To study the cytomorphological presentation of post covid mucormycosis. A retrospective observational study was conducted at a tertiary care center in Northern India for a period of six months, in patients with post covid mucormycosis. The study included 50 cases with post covid mucormycosis. Males with 28 cases (56.0%) were more commonly affected than females. Nose comprising of 36 cases (72.0%) was the most commonly affected area, with nasal cavity showing 24 cases (48.0%) being most common site within the nose. 36 cases (72.0%) were positive exclusively for Mucormycosis. 10.0% cases of mucor showed superadded bacterial infection. Candida was seen in 03 cases (6.0%) and aspergillosis in 02 cases (4.0%). There were 6.0% cases of mucormycosis with associated chronic osteomyelitis. All the patients had a history of steroid use throughout their coronavirus treatment. A rare but fatal fungal infection (mucormycosis) has a strong association with covid-19 infection, in active as well as recovered patients, particularly in those with co-morbid medical conditions and treated with high doses of corticosteroids.
Program Evaluation of Career Development Services in Five Turkish Schools: A Preliminary Study
Authors: Ozdemir Nurten Karacan , Nassar Sylvia C. , Karabay Ersoy , Ayaz Ahmet 
Published: March 2022

School counselors in Turkey, like in many other countries, are tasked with providing career development services within the broader school curriculum. Yet, both globally as well as in Turkey, the unemployment rate among youth continues to rise. In addition, Turkey is home to thousands of Syrian refugees largely concentrated in four cities, creating another layer of challenge for school counselors as career development providers. Effective programs are essential more than ever before, yet very few rigorous efforts at evaluating such programs are in place. In Turkey there are some recent policies governing both career practices and their evaluation, which represents a promising beginning for evaluating these programs locally and nationally. This preliminary qualitative study aims to provide such an example of program evaluation by measuring six key components as identified by the Career Builders Toolkit, an empirically based tool designed to develop and evaluate career and workforce development programs. Five school counseling programs in the city of Gaziantep, Turkey (which is among the cities with a very high Syrian refugee populations), were purposefully selected. Their program materials were content analyzed and, encoded around the Career Builders Toolkit six key components, were rated as being Sufficient, Existing, or Absent, thus providing information about the growth areas still needed in these school-based career development curricula. Among the largest growth areas identified were trainer curriculum and evaluation. Implications for policy, research, and practice are provided based on a Tripartite Model of Program Evaluation.

Attracting high quality candidates with relevant and pertinent experience to any profession is often a challenge. A UK based research project is presented that employs a protean lens to examine the motivations and expectations of career changers who have recently moved into the field of career guidance and counselling. The research comprised of a mixed methods design, utilising an online self-completed survey and interviews aimed at practitioners who have transitioned into the careers field over the last five years. The data reflects practitioners working in a range of settings including, schools, further education colleges and higher education. The initial findings present several important issues for the careers field in the UK which may have wider applicability. Respondents transitioned from a diverse range of professional backgrounds including HR, education management consultancy and research. A common motivation focused on supporting and influencing a social justice agenda. The research identifies that the field is successful in recruiting highly qualified and experienced candidates, the challenge is about diversity and attracting a workforce that better reflects the populace.
Career Transition of Non-European Graduates from European High Education Institutions: Implications for Career Practice
Authors: Zeltner Erik 
Published: March 2022

Based on several case studies of career services for international students and the transitional experience of non-European graduates from study to work, I provide an integrated analysis of transcripts of semi-structured interviews conducted with career representatives and non-European graduates from German, UK and Dutch universities. I discuss the implications for career practice in light of individual perspectives of non-European graduates, higher education career services and other related institutions. The article reveals factors for career planning and development considering cultural gaps ranging from language issues to differences in the higher education system or recruitment procedures as well as a lack of career provision for international students. It illustrates how career services have reacted to these issues by creating new strategies, including the job role of a career specialist for international students, and suggests new directions for further research and the career development of non-European graduates with regard to participating universities and from a broader institutional perspective.
Microdialysis-directed Intra-tumor Pharmacokinetic Modeling of Methotrexate in Mice and Humans
Authors: Alsulimani Helal H. , Kim Jonghan , Sani Shabnam N. 
Published: March 2022

Purpose. To develop a quantitative pharmacokinetic model to characterize the disposition of methotrexate (MTX) at tumor site in tumor-bearing mice and to predict MTX concentrations in the human tumor. Methods. The plasma profiles of MTX were obtained from normal mice, while microdialysis technique was employed to characterize the time course of MTX in tumor from breast tumor-bearing mice. Disposition profiles of plasma and tumor were analyzed by a hybrid physiologically-based pharmacokinetic (hPBPK) model that incorporates physiologically-relevant parameters such as tumor blood flow and volume, while plasma concentrations were used as a forcing input into the vascular-interstitial spaces of the tumor. The plasma profiles were initially described by a biexponential decay model to obtain a forcing function that enters into the vascular-interstitial spaces in the tumor. Using a defined forcing function, the tumor free concentrations were fitted to the hPBPK model. Based on the model developed, sensitivity analysis was conducted with a perturbation of PK parameters to predict different scenarios of intratumoral MTX transport. The relevant physiological PK parameters from the mouse model were then scaled-up and utilized to simulate human tumor concentrations. Results. The mouse hPBPK model adequately characterized the concentration-time profiles of MTX in both plasma and tumor and produced various transfer rate constants between plasma and tumor. Our model was also able to reasonably predict MTX concentrations in the human tumor when human physiological data were utilized. Conclusions. The hPBPK model was able to quantitatively characterize the atypical transport of MTX in the tumor, supporting the idea that microdialysis is a valuable tool to study tumor biodistribution of drugs and to predict tumor concentrations in humans based on the pre-clinical data. This information can ultimately aid in the development of anticancer drugs with improved PK profiles. This article is open to POST-PUBLICATION REVIEW.
