Abstract Bacillus and Paenibacillus spp. are sporeforming bacteria with the ability to survive the pasteurization process due to their spore structure. These bacteria can produce different enzymes that negatively affect the quality of dairy products, reducing the shelf-life of fluid milk and limiting the market for powdered milk. Therefore, the control of sporeformers is crucial to improve the quality of fluid products and to reach specific international powder markets thus benefiting the US dairy industry. In this presentation an overview of sporeformers associated with the supply chain (fluid, condensed milk and dry powder) will be presented along with potential interventions that may be applied at the farm level to control these microorganisms. It has been previously reported that effective cleaning of teats, changes in bedding material, and CIP procedures could be potential interventions to decrease sporeformers in milk. Additionally, the type of sanitizers (i.e. iodine or chlorine based) used in the parlor could have an effect in this microbial population. These potential interventions have been the subject of research at the University of Nebraska – Lincoln, with some of the interventions showing to be successful in improving the quality of raw milk. This presentation will provide a brief overview of spore research done at UNL in the last five years, along with results obtained so far from interventions at farm level to reduce sporeforming bacteria in raw fluid milk.

The study was undertakento detect the type of adulterants and preservatives added to the incoming fluid milk from rural areas to the Barisal city of Bangladesh. Total fifty milk samples were collected from five different entry points of Karapure, Dabdopia, Shaestabad, Goriarpar and Khanpura of Barisal district where ten samples were taken from each entry point. The results indicated that, 100% of the milk samples were adulterated with water irrespective of collection points and months. Cane sugar, powdered milk and starch were detected as 26.0, 14.0 and 12.0% in the milk samples, respectively. Two types of preservatives namely formalin and sodium bicarbonate were detected in the fluid milk from the study areas. Out of all samples, 10.0% was adulterated with formalin and 20.0% with sodium bicarbonate. However, none of the samples contained either hydrogen peroxide or borax. There was a positive relationship between day temperature and intensity of adding preservatives to the fluid milk. As the day temperature increased, the number of preservative positive samples also increased in a linear fashion and vice versa. It could therefore be inferred that, the consumers need to be more cautious regarding the quality of raw milk specially in summer season.DOI: http://dx.doi.org/10.3329/bjas.v41i2.14126Bang. J. Anim.

Somatic cells are the most essential factors naturally present in milk, and somatic cell count (SCC) is used as an indicator of monitoring mastitis incidence in the herd and also to assess the quality of milk. In addition, SCC is frequently used to determine quality payments to dairy producers. The SCC is directly related to get maximum milk production from individual cow and a lower SCC indicates better animal health, as somatic cells originate only from inside the animal's udder. SCC monitoring is important because as the number of somatic cells increases, milk yield is likely to fall, primarily due to the damage to milk-producing tissue in the udder caused by mastitis pathogens and the toxins they produce, particularly when epithelial cells are lost. Keeping low SSC will allow good quality more raw milk and provide a better product to milk processors whether used as fluid milk or converted to milk based products. Somatic cells containing lipolytic and proteolytic enzymes lead to degrade major nutrients fats and proteins, respectively. Elevated SCC is related to udder inflammation, which leads to alter the normal microbial count and physicochemical parameters of milk, as well as the quality of heat treated fluid milk and milk based product. The objective of this review is to discuss on the SSC and endogenous enzymes released from somatic cells in raw milk as well as effect of somatic cells count and their endogenous enzymes in processed milk and milk based products.Asian J.

This chapter introduces the description of wiki appropriation. It considers the tool inclusion in an online educational innovation, supported in student and group-centered learning approach, to improve the quality of the blended learning offered. It states that the university course of educational technology, through wiki application as an appropriated methodology, beyond its consideration as a Web 2.0 tool, gives the opportunity to enhance the student protagonism into the deepening of the conceptual field of the subject by a collaborative knowledge construction. The evidence shows that the application worth to develop the learning strategies towards the student comprehension and its social skills in universities contexts. The results shows that the transformation of reactive attitudes into creative ones is a long process of change mediated by emotions and metacognitive work. Both facilitate a change of the students’ focus, perspectives, and mentalities, understandable by the help of collective learning, among diverse variables.

The Quality Control Committee laboratory is a unique organization which was started approximately 32 years ago by Dr. Harold Macy of the University of Minnesota. The dairy industry operates a laboratory which does most of the official testing for the health agencies in the Minneapolis-St. Paul market. With higher costs of operations many health agencies are trying to find ways of saving money, and still have a satisfactory laboratory program to protect the public's health. Some health agencies are using industry laboratories, and the cost is passed on to the customer rather than the taxpayer. The laboratory functions are to evaluate the quality of the raw milk supply from 4238 Grade A producers, and the finished products from 17 processing plants. The laboratory also does the official butterfat testing for the Federal Milk Market Administrator for Order 68. This organization is supervised by a Steering Committee of nine individuals who represent the University of Minnesota; the producer cooperatives, who supply the raw milk; and the Grade A fluid milk processors from the Minneapolis-St. Paul market. All of the routine results from the laboratory are provided to the health agencies. The health agencies and laboratory manager have a close working relationship to coordinate the program. In order for an organization like this to work, it takes cooperation from all parties involved.

An important factor along with the availability of food is its quality. It depends, among other things, on the type of plant protection products used and the method of their application. This manuscript presents research on the possibility of using a shielded band sprayer in field onion cultivation. The shielded band spraying technology presented in this article is the subject of a patent application (application number P.428494-The prototype of the machine was produced in Poland in cooperation with the University of Life Sciences in Poznań). The research consisted in comparing the quantity and quality of the obtained crop, based on various methods of reducing the weed population. The research results indicate that the proposed shielded band spraying technology may affect the food quality (the active substance is not sprayed on onion plants) and profitability of farms (less use of plant protection products).

The article deals with the issue of improving the quality of learning a foreign language, namely the ways to eliminate the problems that occur during teaching the subject in distance learning mode. By means of the Ishikawa diagram the basic groups of factors that affect the quality of learning a foreign language specifically in distance learning mode are figured out. After that the factors that cannot be affected directly by a teacher are excluded from consideration. The remaining factors are carefully considered in order to find which one of them is the best in terms of neutralizing the stated problem. A number of modern methods of teaching foreign languages is analyzed; as the result, a range of indicative tasks for qualitative control of learning a foreign language is proposed, with basic features of distance learning taken into account. In conclusion it is pointed out that the proposed tasks can be used by the university tutors to enhance the quality of control of learning a foreign language in distance learning mode.

Abstract This article examines how written feedback is used to support the production of texts for purposes of reuse. The case study refers to an entrepreneur training program at the University of Texas at Austin. In the program, Korean startups are trained in understanding the US market, and developing pitches that convince US investors. They are supported by Quicklook® reports. A Quicklook report delivers snapshots of the market receptivity for the startup’s product. Market analysts write the reports. In the final stage of drafting, program staff members supervise the report author. This study investigates how supervisors use commenting and how the goal of creating a highly reusable text source guides the feedback process. The database was examined quantitatively (frequency of drafting and commenting) and qualitatively (functional comment types). The results offer valuable insights into actual writing processes in business settings and how professionals interact to ensure a reusable product. The findings indicate a broad range of comment functions. Overall, we distinguish two main categories: feedback activities focusing on Quicklook reports as reusable resource, and feedback activities focusing on collaboration and workflow. Each category includes functional comment types. Further research is needed to learn more about professional strategies of reflecting on text quality, the quality of assessments, or the ratio between detected and real deficiencies of a document.

PURPOSE The purpose of this manuscript is to present the comorbidity between epilepsy and mental disorders. Epilepsy is a widespread, socially significant disease that has been the subject of medical literature and practice since ancient times. METHODS We have used a contingent of 100 epileptics, which were treated at the Neurological Clinic of the University of Medicine and Pharmacy "Prof. Dr. Stoyan Kirkovich" in Stara Zagora. RESULTS We found that in percentage ratio, out of the epileptic patients eighteen had mental illness. Out of these eighteen, depressive patients were 27.8%, which fell within the range indicated in the world literature. CONCLUSIONS As a conclusion, we suggest that the clinical assessment of the quality of life in epilepsy provides some opportunities for its improvement and should take its place in the bio-psycho-social approach to the disease.

Sound level data and occupancy data has been logged in five restaurants by the research team at the University of Nebraska - Lincoln. Sound levels and Occupancy at 10 second intervals were documented over time periods of two to four hours during active business hours. Noise levels were logged with dosimeters distributed throughout each restaurant, and occupancy was obtained from images recorded by infrared cameras. Previous analyses of this data have focused on average sound levels and statistical metrics, such as L10 and L90 values. This presentation focuses on each restaurant's Acoustical Capacity and Quality of Verbal Communication, as introduced by Rindel (2012). Acoustical Capacity is a metric describing the maximum number of persons for reasonable communication in a space, calculated from the unoccupied reverberation time and the volume of the space. Quality of Verbal Communication is a metric describing the ease with which persons in the space can communicate at a singular point in time, depending on the reverberation time, the volume of the space, and the number of occupants in the space.
