ABSTRACTPeanut shell (PS) infusion has been shown to be antithrombocytopenia, but there has been no research on safety standards. This study aims to identify the symptoms of toxic effects, the potency of toxicity and histopathology of liver male Balb/C mice after a single dose of PS infusion. This research uses randomized matched posttest only control group design. Twenty five mice were divided into 5 orally dosage groups, ie, PS infusion with a dose of 0,026; 0.052; 0.104; 0.208 g/20gBW; and negative control of CMC Na 0.5%. The observation period is for 14 days. The results showed that single dose of PS infusion had a pseudo LD50 value ie > 0.208g/20gBW which was practically non toxic. Symptoms to watch out for the BW infusion were passive behavior, bradycnea, hair color change, hair loss, and weight loss at doses of 3 and 4. It is unclear whether liver damage ie inflammation, necrosis, and albuminous degeneration caused by PS infusion or other causes.keywords: acute toxicity, infusion, peanut shell

The current study aimed to investigate whether peripheral modulators of serotoninergic function and neurohumoral factors’ changes in athletic horses during an official jumping competition, and to evaluate their relationship with the physical performance of competing horses. From 7 Italian Saddle mares (6–9 years; mean body weight 440 ± 15 kg), performing the same standardized warm-up and jumping course during an official class, heart rate (HR) was monitored throughout the competition. Rectal temperature (RT) measurement, blood lactate and glucose concentration, serum tryptophan, leucine, valine, the tryptophan/branched-chain amino-acids ratio (Try/BCAAs), dopamine, prolactin, and non-esterified fatty acids (NEFAs) were assessed before the exercise event (T0), at the end of the competition stage (5 min ± 10 s following the cessation of the exercise, TPOST5), and 30 min after the end of competition (TPOST30). Highest HR values were recorded during the course and at the outbound (p < 0.0001); blood lactate concentration and RT increased after exercise with respect to the rest condition (p < 0.0001). Lower leucine and valine levels (p < 0.01), and higher tryptophan, Try/BCAAs ratio, and NEFAs values were found at TPOST5 and TPOST30 with respect to T0 (p < 0.0001). A higher prolactin concentration was found at TPOST5 and TPOST30 compared to T0 (p < 0.0001), whereas dopamine showed decreased values after exercise compared to rest (p < 0.0001). Statistically significant correlations among the peripheral indices of serotoninergic function, neurohumoral factors, and athletic performance parameters were found throughout the monitoring period. The findings provide indirect evidence that the serotoninergic system may be involved in fatigue during jumper exercise under a stressful situation, such as competition, in which, in addition to physical effort, athletic horses exhibit more passive behavior.

Passive Behavior

The effect of dry grinding on 304L stainless steel’s passive behavior is compared to two other surface finishing (mechanical polishing down to 2400 with SiC emery paper and 1 µm with diamond paste, respectively). The characterization of the surface state was performed using scanning electron microscopy, transmission electron microscopy, 3D optical profilometer, and X-ray diffraction. Results indicate that each surface treatment leads to different surface states. The ground specimens present an ultrafine grain layer and a strong plastic deformation underneath the surface, while an ultrafine grain layer characterizes the subsurface of the polished specimens. Grinding induces high residual compressive stresses and high roughness compared to polishing. The characterization of the passive films was performed by electrochemical impedance spectroscopy and Mott–Schottky analysis. The study shows that the semiconductor properties and the thickness of the passive films are dependent on the surface state of the 304L stainless steel.

Feminist Attitudes

The present study examined the effects of two subject variables (sex of subject and feminist attitudes) and two strategy variables (strategy aggressiveness and locus of responsibility for change) on the perceived effectiveness and desirability of four rape reduction strategies. Fifty-three females and 36 males served as subjects in a 24 factorial design. Although women rated all strategies as more effective and desirable than did men, attitude toward sex roles was a more pervasive determinants of patterns of perceived effectiveness and desirability than was subject sex. Generally, aggressive strategies were rated as more effective than nonaggressive strategies, and strategies placing the locus of responsibility for change on women were considered more effective than strategies requiring men and society to take action. Strategies that were consistent with sex-role stereotypes (women avoiding rape by passive behavior and men and society fighting rape by aggressive treatment of rapists) were seen as more effective than nonstereotypic strategies. Profeminists found the nonstereotypic strategies to be more desirable, however, and they also rated as relatively more desirable those strategies that placed responsibility for change on men and society. The results are discussed in terms of the importance of sex-role attitudes rather than subject sex differences in reducing rape.

Article presents the results of testing managers’ behavior and response towards business environment. The study develops ideas how to extend current management theory with behavioral approach. Research method is based on in-depth empirical qualitative analysis, results are subject of quantitative verification using statistical methods which allows reaching better results. Research proceeds inductively, it means that new knowledge is generated as outcome and matched to theories. Decisions are examined as responses towards business environment components, correlations and significances between active or passive managers’ behavior are demonstrated. Proactive managerial approach is characterized by frequent change and diversification in suppliers, customers, human resources and product portfolio. As a conclusion, managerial response can be interpreted as a product of managers’ activity, personal preferences and abilities. The re-orientation towards recognition of active or passive behavior is developed and matched towards current theories. It can be assumed, that the current scientific discussion is potentially relevant in seeking to explain the role of individual manager. In summary, the analysis and the outcomes have proved managers’ exceptional flexibility in counteracting actively the shortcomings of external context.
