In the present paper the influence of season on the peak production, the duration of the ascending phase, the persistency of lactation, the 12 month production, and the live weight of the cows in the Ayrshire herd of the University of Helsinki experimental farm Viik are investigated. The material consists of cows calving during the period 1950—1965. During this time the indoor feeding was very intensive, satisfying all the nutritional requirements of the cows. At the same time the pastures were intensively cultivated. The size of the herd varied between 60 and 70 cows. The cows were divided into three groups: 1) spring calving cows, 2) cows calving during the pasre season, and 3) autumn calving cows. During the pasture season the peak production of cows in first lactation is c. 2 kg and of cows in later lactations c. 3.5 kg lower than during the indoor feeding period. The peak production of spring and autumn calving cows is on an average approximately the same. The duration of the ascending phase of cows calving during the pasture season is 6—10 days shorter than during the indoor feeding period. The length of the ascending phase is approximately the same for spring and autumn calving cows. The influence of season on the yield increase tangent, which is a measure of the rapidity of yield increase, is negligible. Cows calving during the pasture season and in the autumn are considerably more persistent in their lactations (P2:1-values higher) than cows freshening in the spring. The persistency values of cows calving during the pasture season and in the autumn are on an average approximately equally high. The 12 month lactation yields of autumn calving cows in the different age groups are 400—600 kg, i.e.c. 10 % higher than the corresponding values for cows freshening in spring and during the pasture season. The lactation yields of cows calving in spring and during the pasture season are on an average approximately equally high. The superiority in lactation yield of cows calving in the autumn compared to cows calving in the spring is due to the better persistency of lactation of the autumn calving cows. On the other hand the superiority in lactation yield of autumn calving cows compared to cows calving during the pasture season is due to the higher peak production of the autumn calving cows. The lactation yields of cows calving in spring or during the pasture season are approximately equally high. During the pasture season the average live weight of the cows is 20—30 kg less than during the indoor feeding period, which is due to the smaller contents of the digestive tract of the cow during the pasture season.

Beta Glucosidase

The domination of microorganisms characterized by excessive activity of the so-called fecal enzymes may be one of the reasons of the large intestine cancers. These enzymes are mainly those that belong to the hydrolase and reductase classes and their excessive activity may lead to disorders in the functioning of the digestive tract. The aim of tise research was to determine the activity of beta-glucuronidase and beta-glucosidase of Lactobacillus and Enterococcus strains isolated from the feces of healthy children, aged 1 and 8, and adults, aged 30 and 80. The analysis included 10 strains isolated from the feces of individuals in each of the age groups. beta-glucuronidase activity in the case of the isolates from children, depending on the strain, equaled from about 0.15 mM/h/mg of protein to 0.26 mM/h/mg of protein and was lower, respectively, by 52.35% and 57.81%, than the beta-glucosidase activity. Simultaneously, the activity of the Lactobacillus enzymes from children was 2.4 times higher, and in case of the isolates obtained from adults they were 4.6 and 2.7 times higher than the activity of the Entercoccus enzymes. The highest beta-glucuronidase activity was observed in Lactobacillus isolates coming from an 80-year-old subject. The differences between the activity of Enterococcus beta-glucuronidase isolated from the feces of 1 and 8 year old children were statistically insignificant. On the other hand, in the case of the subjects aged 30 and 8 the isolates were characterized by activity lower by, respectively. 48% and 37% than the isolates coming from children. The highest beta-glucosidase activity was discovered in the case of Lactobacillus and Enterococcus coming from children, which was higher by 32% than the activity of the isolates from adult persons. Therefore, it was determined that the activity of beta-glucuronidase of Lactobacillus strains isolated from feces from people aged 80 was the highest, and the isolates of the examined microorganisms coming from children were characterized by the highest beta-glucosidase activity.

The Difference

The purpose of this study was to investigate the prevalence of playing-related musculoskeletal disorders (PRMDs) among Japanese female classical pianists of different age groups. The causal factors for PRMDs also were examined. A group of 203 senior pianists, including piano teachers and students with piano majors at high schools and colleges, were surveyed using questionnaires. Results showed that 77% of these pianists suffered from PRMDs in at least one of their body portions. This value was larger than those reported in Western countries. Forty-four percent of these were serious enough to warrant medical treatment, which was a lower rate than reported in Western countries. The difference in these numbers may reflect the current state of understanding of PRMDs among Japanese pianists and their educators. The prevalence of PRMDs was found to be age-dependent. In the student groups, the finger/hand had the highest rate of PRMDs, followed by the forearm and shoulder. The senior group, on the other hand, had the highest PRMD incidence at the neck/trunk, followed by the forearm and hand/finger. Care may need to be exercised for these differences. The results also indicated that prolonged daily practice (>4 hours), playing chords forcefully, eagerness about practice, and nervous traits were found to contribute to the development of PRMDs in these pianists. Hand size was, on the other hand, not a significant risk factor of PRMDs.

Covid-19 are one of the viruses that were widely spreaded in 2019 and are still separate until nowadays. Thailand is one of the countries that are highly infected. The majority of people who are infected with this virus tend to have mild to severe respiratory symptoms. Furthermore, anyone can get sick, and it can lead to death. However, the most common symptoms of this virus are fever, cough, tiredness, and loss of taste or smell, on the other hand, characteristics in a minority of people, such as diarrhea and headaches. Due to the impact of the Covid-19 virus, people have to change their lifestyle to the online form. These changes have impacted mostly on economics and education in particular countries, so this problem also affects anxiety among high school students; who must prepare to apply to the university during the COVID-19 outbreak. In addition, we have collected 151 answers from high school students by surveying in order to know the feelings for entrance to the university during the pandemic situation. We found out that 81.3% of the students are highly affected by covid, and only 0.7% of students are slightly affected. We also found out that 55% of the students are worried about university entrance, and only 2.6% of the students were not worried at all. According to the result, most of the students in Thailand are facing the problem about their education and their entrance for the university which are caused by Covid-19. This may lead to illnesses like depression and anxiety. Keywords: Students, Learning, COVID-19, Thailand, University.

Request Strategies

This research aims to analyze the request strategies used in an American TV Series entitled Full House season 7 episodes 1-12. The main characters are family members from three different age groups (adult, teenager, and children). This research attempts to see if there is any difference on the choice of request strategies used by the three age groups. Blum-Kulka and Olshtain’s (1984) theory on request directness level is used to classify the requests. Relative power and social distance are also studied to see how they influence the characters in making their requests. The results show that mood derivable is the most frequent strategy used by all age groups. Specifically, direct request is highly used by the adult age groups. On the other hand, indirect request is mostly used by the younger age groups. The results also show that all age groups tend to use direct strategy when the social distance is negative. However, when the social distance is positive, the choice of strategy depends on the authority of the speaker.

This work undertakes a systematic reconstruction of the debates that took place over the course of several decades up to the beginning of the 21st century between Derrida on the one hand and Searle and Habermas on the other. It shows that the linguistic theories and the theories of communicative understanding developed by Searle and Habermas are based on inferences from the contingent individual case to the general. Searle draws ontological, Habermas anthropo-political conclusions, both with essentially naturalistic signatures. Derrida, on the other hand, raises epistemological objections and consequently develops a metaphysics of free subjects for whom conversation cannot necessarlily be presumed. The explicit dedication to ethics in Derrida's late work is due to his insight that the possibility of language and understanding is due to silence. Derrida's lasting merit lies in enriching the philosophy of language with a secretology.

The relationships between actuarial and pure mathematics are curious. Actuaries have contributed to the development of mathematical theory: it is sufficient to mention, as examples, Fredholm of an earlier, and Cramér of a more recent generation. Scandinavian mathematicians, in particular, have been concerned with a very special type of stochastic process, reflected in the collective theory of risk, and the work of Philipson, Ammeter and others in this field is well known to readers of this Bulletin. However, the main stream of the theory of stochastic processes has little contact with actuarial applications.On the other hand, many actuaries have studied and assimilated pure mathematics and have thrown light on actuarial matters by describing their own preoccupations in the terminology of modern, often abstract, mathematics. E. Franckx is one of their number.The Instituto di Matematica Finanziaria of the University of Trieste (Faculty of Economics and Commerce) has published a booklet entitledEssai d'une théorie opérationnelle des risques Markoviens which contains three lectures delivered by Professor Franckx in Trieste and a contribution which he presented to the 17th Congress of Actuaries, held in London in 1964.

Contemporary higher education in Ghana and many parts of Africa has European colonial antecedents. In spite of the many goals that it aspired to achieve, a preoccupation was to nurture an elite group. Though widely used, the concept of elite and elitism is vague and hardly conceptualized. It hoovers from status—occupants of the apex or top echelons of an organization/society, to consumption—people with immense wealth. Influence, on the other hand, seems to be a common denominator in both cases. But, does this capture the scope of the phenomenon? This article engages people who have worked in different capacities in Ghana’s higher education space to examine the deeper meanings that could be embedded in elitism, elicits conceptualizations of elitism, and further finds out how elitist higher education is in Ghana. Ultimately, the article intends to initiate a conversation on whether indeed there are elites being produced from the university system. This study was done with reference to an empirical study on decolonizing higher education in Ghana.

Fieldwork placement is a complicated and involved task. On the one hand, it requires insightful, professional judgement, but on the other hand, it includes numerous routine administrative and clerical tasks. To deal with fieldwork placement more efficiently and effectively it was decided to computerize the fieldwork placement system at the University of Western Ontario, London, Ontario. This paper describes the system developed and the resultant data base. The potential applications of the data base and the implications for students, facilities, educational programs, professional governing bodies and research are discussed.

1. The structure of the cattle population (4 June returns), as well as of cattle sales to the Ministry of Food, have been illustrated.2. The trends in cattle production show the definite changes from that of the traditional storestock rearing to that of milk selling.3. A considerable part (38·2%) of the total graded animals slaughtered for beef are the ‘wastage’ animals from the breeding and dairying herds.4. Reference has also been made to the high proportion of ungraded cows (36·7% of the total cows) purchased by the Ministry. The ungraded cattle, however, are only 17% of the total sales. On the other hand, the ungraded ‘wastage’ cattle contribute 90% of the total ungraded cattle.5. More heifers than steers were sold for slaughter, and it has been shown that the average live weight of the graded steers is nearly 224 lb. heavier than that of the heifers.

Integrating dependability in self-optimizing systems is a challenging task. Self-optimizing systems incorporate on the one hand the opportunity to apply novel solutions to complex mechatronic systems, but on the other hand constitute a possible risk because of non-determined behavior. The dependability concept in this paper covers both aspects: Increasing safety with self-optimization and minimizing the risk of self-optimization. This dependability concept is combined with the self-optimization process of the active guidance module which is currently under development at the Collaborative Research Center 614 at the University of Paderborn.
