Abstract :

The aim of the present study was to detect the relation between oxidant/antioxidant status and postpartum anestrous (PPA) conditions in dairy cows.The postpartum period is a very critical time that influenced mainly in cattle reproduction. A little information is obtainable in literature concerning antioxidant defense mechanisms during anestrus.The purpose of the following study is detection of the relation between oxidant/antioxidant status and postpartum anestrous (PPA) condition in dairy cows. Seventy five postpartum anestrous (PPA) and twenty five normal cyclic Holstein Friesian pluriparous dairy cows were selected on the basis of their reproductive history gained from farm records. Depend on the rectal findings and ultrasonography in addition to progesterone profile; the studied animals were classified into three groups (each 25 animals) as inactive ovaries group, persistent corpus luteum group and silent heat group. Blood samples from anestrous and normal cyclic animals were gathered at day 0, day 10, day 21. These samples were utilized for detection of MDA, Vitamin C, Nitric Oxide and Total antioxidant capacity. Results of the present study revealed that MDA and Nitric Oxide were be significantly (p<0.05) higher in the groups of PPA than the normal cyclic group. Vitamin C (Ascorbic acid)  levels were seen to be significantly (p<0.05) lower in normal cyclic animals in comparison to inactive ovaries group and persistent C.L group ,while there is no significant difference with the silent heat group .

No statistically significant difference was detected in the total antioxidant capacity between the group of silent heat and the normal cyclic group, while the groups of persistent C.L and inactive ovaries were found to have statistically significant difference (p<0.05) with the normal cyclic group. It is concluded that supplementing diets with optimal levels of micronutrients with antioxidant capabilities is a good advice to farmers to avoid post-partum anestrum. Moreover, early approaches to conflict the progression of stress and to promote the antioxidant defense mechanisms of dairy cattle during times of increased metabolic demands appears to be Pertinent.

Abstract :

Different chemical compounds were tested as buffers for the bovine milk acid phosphatase catalyzed reactions to elucidate the presence of an additional optimum pH value. Imidazole, histidine, alanine, glycine, malate, oxalate, succinate, citrate and acetate were studied as buffers, using p-nitrophenylphosphate or inorganic pyrophosphate as substrates. An optimum pH range between 4.5 and 6 was obtained for all the buffers studied. However, with glycine, and alanine, an additional pH optimum around 3 was observed. The specificity constant value (Vmax/Km), at pH 3, for glycine, was about twice the value obtained at pH 5 with acetate. The additional activity at pH 3 was also observed for other acid phosphatases. Our results suggest the existence of an inverse ratio between the negative character of the buffer and the reaction velocity.

Abstract :

The purpose of the present study was the evaluation of the effects of Greek traditional dancing programs on middle-aged people’s life. Seventy one subjects (60 women and 11 men) 51.92+4.99 years old, members of different dance clubs, participated in the research. All the subjects participated in a group dancing program for learning and performing Greek traditional dances once a week. The effects and changes in life due to participation in the Greek traditional dancing program were measured through questions by Chewing, Yu και Johnson (http://www.krapu4.com/taichi/research/Chewing Yu Johnson B. htm#emotions). For data analysis were used the descriptive analysis and Pearson chi-square test of the SPSS version 17 for windows. From the results, it was proved that almost 90% of the subjects supposed that their participation in the Greek traditional dancing program had an effect on their lives. The bigger percentage declared that the participation in Greek traditional dances offered them joy, well-being and calmness (33.30%), as well as many effects on their bodies (33.30%), while a smaller percentage claimed that their participation in the program offered them sociability-participation in a group (16.70%) and activity increase (16.70%). In addition, more than 4/5 (86.50%) believe that their participation in the Greek traditional dancing program has changed their confidence concerning their mobility or possible falls. About three-quarters of the subjects (73.70%) consider that their participation in the program of Greek traditional dances influenced in any way their everyday activities. The majority (78.90%) believe that their physical activity has changed as a result of their participation in the program of Greek traditional dances. Finally, all people think they have been benefited from their participation in the Greek traditional dancing program, which is very important. In addition, the Pearson chi-square test showed a significant effect (x2=8.15, p<0.05) of the years that the subjects participated in Greek traditional dancing programs on the feeling of people's confidence in their mobility or possible falls. Thus, as the years of participation in Greek traditional dances are increasing, the feeling of people's confidence in their mobility or even the potential falls is increasing. From the results, it was shown that all the middle-aged people suppose that they have been benefited from their participation in the Greek traditional dancing program. The benefits concern their better emotional state expressed in joy, well-being, calmness and sociability-participation in a group, but also their better physical condition, confidence in their mobility and possible falls, increase in their physical activities and the effects on everyday activities. The importance of participation in Greek traditional dances is also worth mentioning. Thus, it could be said that the participation in Greek traditional dancing programs brings about effects and changes on life. Consequently, Greek traditional dances as a regular physical activity may be extremely useful for the quality of life of middle-aged people offering many benefits.

Abstract :

The HEC-RAS one dimensional, free-surface numerical model was used to simulate bed formation in alluvial channels. Based on the hydraulic equations all the hydrodynamic parameters were firstly simulated and then a sediment transport simulation was performed. The model can compute the sediment transport using a hydrodynamic simplification, the quasi-unsteady flow assumption, which approximates a continuous hydrograph with a series of discrete steady flow profiles. The current research work aims to investigate scour depth variation in the region of vertical wall abutments. Numerical computations of scour depth variation around a vertical wall abutment are verified by comparing them with available measurements. Moreover the study reports experimental results of scour depth variation along the center flow line of a channel in the vicinity of a vertical wall abutment. The experimental measurements of bed variation for six different inflow discharges and three different abutment widths, after a specified flow duration, are graphically presented and can be used by other researchers in order to validate their simulations. Comparison between computed results and available measurements of scour depths is satisfactory along the center flow line as the numerical simulation is one dimensional. The one dimensional model gives an accurate estimation of the maximum scour depth near the obstruction and it is applicable for a safe design criteria for the assessment of bridge vulnerability which is very important in river engineering works.

Abstract :

The synthesis of MIPs for two types of templates (herbicides, and flavonoids) and their application in analytical chemistry are discussed. Particular attention has been paid the issue of bonding the template and selection of appropriate monomer in different types of compounds. This short review aims at presenting the molecular imprinting technology (MIT) which is considered as an attractive method to produce impressive receptors for application in analytical chemistry. The challenge of designing and synthesizing a molecularly imprinted polymer (MIP) can be a daunting prospect to the uninitiated practitioner, simply because of the number of experimental variables involved, e.g. the nature and levels of template, functional monomers, cross-linkers, solvents, initiators and even the method of initiation and the duration of polymerization. Indubitably, the most important place of the polymer is its "heart" or the cavity corresponding to the template and the way

Abstract :

Knee osteoarthritis is a common disease leading to pain and disability in an increasing number of people. Since osteoarthritis is a progressive and degenerative skeletal disease, any therapy aimed to deal with it has to face from one side with the management of pain and recovery from disability; and from the other side with the slowing of osteoarthritis progression itself. Biophysical therapies have been shown to be efficacious in the treatment of pain in comparison to a common non-steroidal anti inflammation drug as ibuprofen, and to placebo. Moreover, biophysical therapy showed its effectiveness in the management of low back pain and disability, even at different degrees of intensity. Biophysical therapies exert, very likely, their effects though a resonance phenomenon. The aim of this study was to assess the possible efficacy of a biophysical protocol for knee osteoarthritis. Fifty consecutive patients (age 52.7±13.8), with different levels of pain and disability participate into this study employing an electro medical device (Med Select) to perform the electromagnetic information transfer through aqueous system (Nomabit Base) protocol according to previous reports. Assessment was done at baseline, and after 3 months, by the Oxford knee pain and disability questionnaire. Patients were classified as having a severe (score 0-19), moderate (score 20-29), mild (score 30-39), or satisfactory (score 40-48) knee condition. A global reduction in the knee pain and disability score was observed after 3 months of a single biophysical intervention, in fact mean start level was 2.1±0.71, while mean end level was 0.24±0.52 (p<0.0001). We hope that biophysical treatments are considered for larger and longer trials in order to meet the requirements to be widespread as a possible integrative support to the number of people with knee osteoarthritis in order to both manage pain and disability, as well as slowing the gonarthrotic progression.

Title : Multiperspective Qualitative Research Methodology for Researching Work Stress

Authors : Roland Ferenc Szilas

Download Certificate
Abstract :

Research on work stress is on the rise as evidence is mounting about the negative health consequences and economic losses associated with the phenomenon. Mainstream work stress research utilizes large samples and quantitative, positivist research methodologies. An important alternative research approach complementing these efforts is provided by case-study based and qualitative research methodologies. In this paper, the author proposes a multiperspective qualitative research methodology, bringing together the critical research perspective with an emphasis on deep social structures and the postmodern perspective with an emphasis on the role of language and discourse. The arguments for a multiperspective, qualitative approach for researching work stress are supported by the results of an exemplary case-study based research carried out in a Hungarian manufacturing plant.

Abstract :

The purpose of the present study was to examine the incidence of the injuries in dancers. A hundred and sixty eight dancers (135 women and 33 men) 23.17+6.43 years old, members of different dancing clubs, participated in the research. All the subjects participated only in dancing programs for learning, performing and practicing in any kind of dance and no other form of physical activity, and filled the instrument of measurements concerning general questions as well as questions about injury incidence. For data analysis, descriptive analysis and Pearson chi-square test of the SPSS version 17 for windows, were used. From the results it was shown that the biggest percentage of dancers take hip-hop (25.1%) and Latin American lessons (18.6%). Moreover, the dancers are involved in European dances, classic ballet, modern dance, oriental dances and Greek dances. The subjects participated in dance programs for 4.44 + 4.45 years, 3.16+1.63 days a week, for 2.29+1.30 hours a day. According to the dancers’ statements, 44.62% of them have suffered an injury. The most usual kinds of injuries are muscle strains (22.9%), muscular spasms-cramps (20.15%), callus (13.18%), sprains (12.53%), blisters (11.80%) and abrasions (11.10%). Also, in smaller percentages follow the fractures (3.48%), hematomas (3.48%) and dislocations (1.38%). The most significant causes of the injuries are poor warming-up (21.92%), fatigue (16.64%), clumsiness (15.68%), bad technique (10.48%), and concentration (10%), and  in smaller percentages performance pressure (7.12%), shoes (5.2%), partner and floor (4.8% both), hour of the day (1.44%), as well as competition and space tightness (7.96% both). Most of the dancers of the present sample (34%), who had an injury, overcame it with medication, 25% needed further medical examinations and 20% overcame the injury with rehabilitation. 16% of the dancers needed rest, while fortunately, only 5% overcame the injury with a surgery. Finally, most of the dancers of the present sample (63.76%) consider that dance teachers, as well as dancing clubs, are concerned very much with injuries prevention (63.76%). Consequently, recognizing, resolving, but above all, preventing the causes of injuries is very important concerning injuries’ avoidance, good physical condition of dancers, reduction of training time loss, continuation of professional career, and continuation of dancing activity of those who have finished their career or are not professionally engaged in dancing.
