短神经肽F(sNPF)肽家族是参与调控昆虫体内各种生理过程的多功能神经激素。它们广泛分布于生物体中，但前体分子中的异构体数量因物种而异，从一个到四个不等。sNPF受体（sNPFR）属于G蛋白偶联受体家族，在多种昆虫目中已有表征，并被证明是哺乳动物泌乳素释放肽受体（PrPR）的同源物。sNPF信号通路通过与其他神经激素（例如类胰岛素肽、SIFamide和色素分散因子（PDFs））的相互作用以调控多种生理过程。其主要生理功能涉及摄食的调节，但观察到的效应因物种而异。sNPF还与觅食行为和嗅觉系统的调节相关。其对摄食及能量代谢的影响还可能间接影响其他重要过程，例如繁殖和发育。此外，这些神经激素还参与昆虫的运动活动和昼夜节律的调节。本文回顾并总结了昆虫中sNPF系统的现阶段研究进展。

This short review is to list pros and cons which are based on the literature and personal experience in cell culture studies related to possible commercial production of artificial meat as functional food. The general view of muscle composition and determinants of meat quality are shortly described. Principles of muscle cell propagation in culture and mutual relationships between different cell types present in this organ are briefly discussed. Additionally, the effects of some cytokines and growth factors for muscle cell growth and muscle tissue development are indicated. Finally, conclusion remarks related to detrimental consequences of meat production to natural environment as well as personal opinion of author on the prospects of artificial meat production are declared.

This work presented the characteristics of two gear teeth finishing methods, due to the properties of gear teeth surface layer obtained at the tooth working depth. These methods are: 1) the teeth carburization, hardening to a hardness of HRC 60-62 and then grinding, 2) the soft gear shaving as the final mechanical treatment and then carburizing and hardening to the hardness of HRC60-62. This work included the test results of the contact fatigue strength carried out on the circulating power system. The Wohler curves were plotted due to the obtained results, as the basis for the practical evaluation of the considered gear finishing methods. The parameters like volume distribution of the voids, content of the retained austenite, compressive residual stress value, but also the results of contact fatigue strength tests, are more favorable for the teeth shaving method than for the teeth grinding method.

The paper concerns numerical analysis of pressure distribution of an oil film on the valve plate in the variable height gap of an axial piston pump. The analysis employs the finite element method. For determination of oil pressure variations in the gap, the Reynolds equation, commonly applied in the theory of lubrication, is applied. The equation is solved numerically with the use of self-developed program based on the finite element method. In order to obtain high accuracy of the results, an adaptive mesh refinement based on residual estimations of solution errors is applied. The calculation results are represented as dependent on the geometric and working parameters of the pump.

Noise, an obvious effect of urbanization, has a negative impact on animal vocalizations and the hunting efficiency of acoustic predators. However, the influence of noise pollution on the spatial distribution of populations remains understudied. The aim was to assess the factors shaping the distribution pattern of an acoustic predator （long-eared owl Asio otus） in an urban-farmland matrix. We hypothesized that the probability of an acoustic predator occurring decreases with growing nocturnal noise emission. This owl survey was conducted in Krak6w （S Poland） on 79 ran- domly selected sample plots （1 km x 1 km）. Six habitat variables （area of parks, woodlands, grass- land, arable land, habitat diversity index, and noise pollution） were identified and correlated with the probability of the species＇ occurrence. Proximity to pedestrian routes and roads, habitat frag- mentation, and noise intensity was also defined at nest sites and random sites. Long-eared owls occurred on 37% of the sample plots. Occupied plots had a greater area of grassland and arable land as well as a lower level of noise pollution than the unoccupied ones. A multivariate model revealed that area of grassland and nocturnal noise emission was significantly correlated with the probability of long-eared owls occurring and that the high probability of occurrence recorded on plots with large areas of grassland was reduced by noise pollution. The noise intensity recorded at nest sites was also significantly lower than at random sites. This study suggests that apart from habitat factors, the distribution of acoustic predators in an urban matrix is driven by noise pollu- tion. This highlights the importance of proper landscape management, that is, maintaining large grassland areas and preventing noise from increasing within them.
