General Aspects

Heavy payload forging manipulators are mainly characterized by large load output and large capacitive load input. The relationships between outputs and inputs have greatly influence about the control and the reliability. Forging manipulators have become more prevalent in the industry today. They are used to manipulate objects to be forged. The most common forging manipulators are moving on a railway to have a greater precision and stability. They have been called the railbound forging manipulators. In this paper one presents the general aspects of a railbound forging manipulator, like geometry, structure, general kinematics and forces of the main mechanism from such manipulator. Kinematic scheme shows a typical forging manipulator, with the basic motions in operation process: walking, motion of the tong and buffering. The lifting mechanism consists of several parts including linkages, hydraulic drives and motion pairs. An idea of establishing the incidence relationship between output characteristics and actuator inputs is proposed.

The Mean

SummaryThe plasminogen content was determined by a casein method in plasma and serum from 20 normal volunteers. The mean plasminogen content was found to be 10.1 ACU (the arbitrary caseinolytic unit defined in such a way that using a 3% casein solution and a digestion time of 20 min. at 37°C, 10 ACU gave an extinction of 0.300). No difference between serum and plasma regarding the plasminogen content was found.Plasminogen was determined in drained and drained plus washed clots prepared from 2 ml plasma. The highest values found in the drained clots were 0.9 ACU/clot and 0.2 ACU/clot in the drained plus washed clots.Plasminogen was also determined in drained and drained plus washed clots prepared from plasma with added purified plasminogen. The plasminogen was recovered in the washing fluid. According to these tests, then, purified added plasminogen is washed out of the clots.The plasminogen content of 20 thrombi obtained post mortem was also determined. The mean value was found to be 0.7 ACU/cm thrombus. Judging from our results, the “intrinsic clot lysis theory” is not the main mechanism of clot dissolution.

Progesterone-containing contraceptives do not have a significant impact on metabolic processes and can be prescribed to patients with systemic (diabetes mellitus, obesity) and other diseases. Desogestrel is a part of oral preparations in a dose of 75 mcg. The main mechanism of its contraceptive action is Suppression of ovulation (in 97% of cases). The frequency of pregnancy is 0.17 for 100 women-years. Progesterone-containing contraceptives should not be considered, as preparations of the second choice when deciding on the issue of family planning. According to the recommendations of the Center for Disease Control and Prevention organization of health, desogestrel is an acceptable contraceptive option for women with somatic diseases, defined tumor pathology and thrombotic states in the anamnesis.

Background: Achalasia and other esophageal dysmotility disorders mimicking achalasia can be associated with cancer. This study aimed to review the main mechanisms for which cancer may develop in esophageal dysmotility disorder patients. Methods: A narrative review was performed. Results: The mechanism for developing squamous cell carcinoma and adenocarcinoma are discussed. Besides, achalasia-like syndromes related to familial KIT-gene mutation and pseudoachalasia are discussed. Conclusions: Knowing the main mechanism for which achalasia can be related to cancer is essential for clinicians to conduct the proper investigation, surveillance, and treatment.

Underlying Mechanisms

Abstract Background Work-related stress shows steadily increasing prevalence rates and has tangible consequences for individual workers, their organizations, and society as a whole. One mechanism that may help offset the negative outcomes of work-related stress on employees’ well-being is recovery. Recovery refers to the experience of unwinding from one's job when not at work. However, employees who experience high levels of work-related stress and are thus particularly in need of recovery tend to struggle to switch-off. Due to the detrimental effects of this prolonged and sustained mental representation of job stressors, interventions promoting recovery may contribute to improvements in employees' mental health. Methods In this randomized, waitlist controlled trial, we will investigate the effectiveness of two 6-week online training programs (cognitive behavioral and mindfulness-based). The sample will include employees working at least part-time during regular work hours. Besides the pre-post-follow-up assessments, the trial will include measurement bursts with the goal of examining the underlying mechanisms. We expect that both interventions will reduce work-related perseverative thinking (PT) compared with the waitlist control groups (primary outcome). Also, we expect that both interventions will result in similar improvements, but the underlying mechanisms will differ (process outcomes). In the cognitive-behavioral intervention group, we expect that the main mechanism responsible for lower PT levels will be an increase in recovery experiences across time. In the mindfulness-based group, we expect that the main mechanism responsible for lower PT levels will be an increase in facets of mindfulness across time. Discussion In the present study, we will investigate mechanisms underlying assumed changes in work-related PT in great detail. Besides evaluating the overall effectiveness of the two interventions in terms of pre-post-follow-up changes, we will look at the underlying processes at different levels—that is, within days, within weeks, across weeks, and between individuals. Accordingly, our study will offer a fine-grained approach to investigating potential determinants, mediators, and moderators of the processes that may, in the end, be responsible for work-related strain. From a public health perspective, if effective, the online training programs may offer valuable, low-threshold, and low-intensity interventions for a broad range of occupations.

AbstractBased on longitudinal data from Germany, we analyze how perceptions of discrimination change once migrants’ integration evolves. Individuals who identify more strongly with the host country, speak the language, have native friends, and are adequately employed report less discrimination overall. However, group-specific analyses reveal that German-born Turks feel more rather than less discriminated against after their language skills and their identification increase. For this group, we find evidence for the “integration paradox”, i.e., the finding that better educated migrants have more rather than less negative attitudes about the host society. Results suggest that attributional processes rather than rising exposure to discrimination might be the main mechanism linking integration to higher levels of perceived discrimination. Obviously, discrimination does not disappear for groups facing salient ethnic boundaries and is met with growing awareness and sensitivity among individuals that have become more similar to the majority of members. This, in turn, by no means implies that perceived discrimination is detached from reality.

In the presented article the problems of interaction between the various branches of Russian law on the basis of legal principles are considered. The author, examining such concepts as “interaction” and “interrelation” states the fact that the issue of interaction of branches of law is considered by almost all researchers only from the position of listing those branches with which their branch of law interacts. At the same time, the construction of branch norms without taking into account the principles of the branch, where and the branch, from which the legal institute is implemented, leads to conflicts. Separate attention in the work is paid to the views of V.A. Riazanovskii and other scholars on the concept of “unity of process” in the context of interaction between the principles of various branches of law. The author examines the interaction of such branches of law as civil procedural law with civil, family law, arbitration and administrative process. The article draws attention to the cases of free treatment of the legislator with the category of “principles of law”, which, in the author’s opinion, leads to significant distortions of the entire branch of law, where principles not inherent in this branch are wrongly implanted. Studying institutes of law as the main mechanism of inter-branch interaction, the author comes to the conclusion about the need for legal regulation of interaction precisely through the principles of a branch of law.
