On leaf-beetles of the genus Palpoxena Baly, 1861 (Coleoptera: Chrysomelidae) from Malaysia and Indonesia

Four new species of the genus Palpoxena Baly, 1861 are described from Malaysia and Indonesia. Palpoxena achehensis sp. n. belongs to the P. bipartita (Jacoby, 1879) species group from Sumatra. This species has red elytra with the basal part black, the maxillary palpomere III is swollen, not flattened, eyes large, the antennomere III is strongly modified hook-shaped; the space between antennal sockets is flattened; the clypeus is with deep and wide excavation almost reaching eyes, the narrow space between them with the tubercle bearing the tuft of bristles on each side; antennae are slender, extended beyond apex of elytra; antennomere III is slightly flattened, antennomeres IV–V are cylindrical. Palpoxena sp. and Palpoxena klimenkoi sp. n. belong to the P. laeta Baly, 1861 species group from Peninsular Malaysia, Sumatra and Borneo. Palpoxena sp. from Sumatra, having the strongly enlarged and swollen protarsomere I, is most similar to Palpoxena shayakhmetovai Kizub, 2016 from Peninsular Malaysia and is possibly a Sumatran subspecies of the latter taxon. Although there are slight differences between them in the body colouration, the shape of the aedeagus and in the length/width ratio of the protarsomere I; it is not described as a new to sciences in this paper. Palpoxena klimenkoi sp. n. differs from other members of the species group by the following combination of characters: elytra dark bluish with narrow basal area; epipleura have very narrow sutural margin and wide apical area brown; antennomeres III–VIII are thickened, about 1.4–1.5 times wider than antennomere II, covered with not dense, short and adpressed setae on the ventral surface; the maxillary palpomere III is half-ellipsoid, with the slightly elongated and sharpened apical margin. Palpoxena parasabahensis sp. n. belongs to the P. variabilis (Jacoby, 1886) species group from Borneo. This new species differs from other members of the group by elytra green with reddish brown apex and entirely brown legs. In addition, only this species has the apex of the antennomere I with the protruding outer corner and the labrum with two long structures on inner side. Palpoxena trusmadiensis sp. n. has elytra green-blue or blue and tibiae darkened. This species differs from all congeners by the shape of the maxillary palpomere III which is slightly enlarged and flattened, but just a little wider than the palpomere II. Figures of the general view and the aedeagus are given for mentioned above and related species. A new key for males of the genus Palpoxena from Malaysia and Indonesia is proposed

A new species of the genus Mimastra Baly, 1865 (Coleoptera: Chrysomelidae: Galerucinae) with cross-like elytral pattern from Vietnam

One new species, Mimastra levmedvedevi sp. n. from the group of species with crosslike elytral pattern, is described from Vietnam. Mimastra levmedvedevi sp.  n. is most similar to M. arcuata from which differs by details of coloration and by the apex of aedeagus with rather narrow, not emarginate tip on the apex. The figures of general view and aedeagus are given for the new and close specie

To the knowledge of the leaf-beetles of the genus Taumacera Thunberg, 1814 (Coleoptera: Chrysomelidae) from Malaysia, Indonesia, and Thailand

Ten new species of the genus Taumacera Thunberg, 1814 are described from Malaysia, Indonesia, and Thailand: T. alexklimenkoi sp. n. from the viridis species-group; T. lamellicornis sp. n. from the insignis speciesgroup; T. pseudoantennata sp. n. from the antennata species-group; T. pseudonigricornis sp. n. from the nigricornis species-group; T. sinabungensis sp. n. and T. trizonalis sp. n. from the deusta species-group. Taumacera bezdeki sp. n. and T. moseykoi sp. n., having long antennae covered long, erected setae and metatibiae with apical process, as well as T. carinatipennis sp. n. and T. unicoloripennis sp. n., having not modified antenna and metatibiae with apical process, are unassigned to any species-group. The figures of general views and aedeagi are given for them and the majority of related species. The new identification keys for males of the antennata and the nigricornis species-groups, as well as for the Sumatran representatives of the deusta species-group with the angulate pronotum are proposed. A new colour form of T. monstrosa (Jacoby, 1899) with darkened elytra is described from Sumatra. Taumacera javanensis (Jacoby, 1895) has antennomeres VII and VIII dilated with distinct spine directed backwards on the latter and is assigned to the antennata species-group. The lectotype of T. javanensis is designated. The following new synonymy is proposed: Taumacera antennata (Mohamedsaid, 1997) = T. musaamani (Mohamedsaid, 2010), syn. n

To the knowledge of the leaf-beetle fauna (Coleoptera: Chrysomelidae) of the Russian Far East

Cryptocephalus (Burlinius) flavolimbatus Pic, 1920 is recorded from Russia for the first time. This species has the aedeagus with the long and thin apical process and belongs to the group of yellow species with a black pattern on the elytra and the distinctly punctured pronotum. New records of Lema concinnipennis Baly, 1865, Chaetocnema kimotoi Gruev, 1980, Neocrepidodera ohkawai Takizawa, 2002, Phyllotreta rectilineata Chen, 1939 in Russia are provided. Photographs of spermathecae and a new identification key for females externally similar species Tricholochmaea ussuriensis Romantsov, 2021, T. semifulva (Jacoby, 1885) and Pyrrhalta flavescens (Weise, 1887) are given for the first time; the general view of T. ussuriensis is imaged for the first time. The material on the rare and little-known species Cryptocephalus gussakovskii Lopatin, 1952 was studied and the lectotype (female) of this species is designated; the paralectotype (male) was probably lost. The original description and futher interpretations of this species incompletely correspond to the lectotype. In the majority of keys this species differs from other representatives of the subgenus Burlinius Lopatin, 1965 only in the anterior margin of the prothorax tooth-like bent downwards, and the images of the aedeagus and the description of male protibiae are absent. According to the original description the male has the protibia curved at the base, and there is no mention of the tooth-like anterior margin of the prothorax. In further works, I.K. Lopatin used only the tooth-like anterior margin of the prothorax (a very rare character within the subgenus Burlinius) to distinguish this species from other representatives of the subgenus. However, he didn’t mention curved male protibia anymore. The description and images of males of C. gussakovskii are given for the first time. All males have strongly curved protibiae with the angularly widened inward distal part. This feature allows to attribute this species to the C. populi species-group. Both males and females of C. gussakovskii have tooth on the prothorax, which distinguishes them from C. populi Suffrian, 1848 and from other yellow representatives of the subgenus. Differences between C. gussakovskii and C. sagamensis Tomov, 1982 from Korea are given; the first species has the smooth, almost impunctate pronotum, the pronotal punctation of latter species is distinct and deep. Two taxa, C. pseudopopuli Schöller, 2011 from South Korea and C. gussakovskii are probably conspecific. Figures of the general view and aedeagi are given for Cryptocephalus flavolimbatus, C. gussakovskii, Chaetocnema kimotoi, Neocrepidodera ohkawai and Phyllotreta rectilineata

Monitoring Of Air Quality Parameters For Construction Of Fire Risk Detection Systems

The analysis of fire developmental process is given, which showed that there are seven stages of fire development, a set of phenomena (factors, signs) of fire risk condition, characterized by a set of defined parameters, corresponds to each stage. Observed that the registration of high staging factors (high ambient temperature, content of CO[2], etc.) means the registration of actual low staging fire (thermal destruction of materials gases, fumes, etc.) - fire risk situation. It is shown that the decrease of registered factor staging leads to construction of fire preventive and diagnostic systems as the lower is registered stage, the more uncertain is connection between the fact of its detection and a fire. It is indicated that with development of electronic equipment the staging of fire situations factors used for detection is reducing in whole, and also it is noted that for each control object it is necessary to choose (identify) the optimal factor, in particular, in many ways the optimal factor for aircrafts are smokes and their TV image

The purposes of the article are: analysis of the reasons of innovations’ low demand from the domestic companies; a search of counteraction measures to existing shortcomings of innovative sphere and companies’ interaction; a research of changes of both internal, and external characteristics of the innovative environment and its approach to the EU countries’ standards in the beginning of the 21st century.Methodology. Methods of the economic and statistical analysis. Theoretical base of the article comprise the national and foreign researchers’ works in the field of innovation management, technological management, and that of the companies’ and economical general development.Results. Poorly positive dynamics of patents growth in comparison with a volume of R&D costs is established in this researching. Almost similar dependence between dynamics of innovative goods and services sales growth in comparison with technological innovations costs was discovered in analysis. The received total integrated estimates of dynamic level of the RF innovative economic development during the period from 1998 to 2015 proved the existence of poorly positive tendency of such dynamics growth.

The Assessment of the Level of Pollution of Slime Pits with Heavy Metals

In drilling and running oil and gas wells the great amount of toxic waste is formed and in the surface of the lithosphere and hydrosphere the great amount of different chemical elements and compounds access, they are needed to be isolated from the environment. The most useful way of isolation is their utilization in the slime pits on the wells territory. Heavy metals are dangerous waste in the drilling slime; they accumulate in soil and under some conditions they in form water-soluble parts and migrate in to the soil. The aim of this paper is to organize the chemical and analytical research of the amount of heavy metals in the drilling slime, and research the mechanism of their spreading on different depth and square in the slime pits typical for the oil site placed in KHANTY-Ugra

Расширение частотной характеристики измерителя импульсного магнитного поля на основе RL-интегратора

Introduction. Measurements of the amplitude-time characteristics of pulsed magnetic fields are required in various research and technology areas. Such measurements are carried out during pulsed magnetic field immunity testing, with the magnetic field pulse rise time being hundreds of ns, and the pulse duration to its half initial value (halfdroop) being hundreds of µs.Aim. To develop a meter of magnetic field strength with a linear conversion characteristic for measuring the pulse rise time, the pulse duration to its half-droop, and the peak value of the pulsed magnetic field strength.Materials and methods. Among several available methods for measuring pulsed magnetic field parameters, the induction method was selected. To obtain a signal proportional to the pulsed magnetic field strength, a signal from the induction transducer is integrated using a self-integrating induction transducer (RL integration) or by using an external RC integrator. The former method shows good results when measuring signals with a duration of hundreds of ns; however, this method is inefficient when measuring the parameters of longer-duration pulses. The latter method is used to determine the parameters of signals with a duration of hundreds of µs and ms; however, this method gives a large error when measuring the parameters of signals with a duration of hundreds of ns and less. The consecutive use of the two integration methods leads to an additional error in the measurement of the pulse duration to its half-drop.Results. A setup for determining the required magnetic field pulse parameters using a pulse magnetic field meter based on an RL integrator was developed. The relative measurement errors comprised 10, 10, and 9 %, respectively. The developed setup eliminates the error caused by losses in the active resistance of an induction transducer, thus enabling the pulse duration to its half-droop to be measured without additional errors under the pulse rise time of hundreds of ns and the pulse droop time of hundreds of µs.Conclusion. The development of a functional converter made it possible to extend the frequency response of a pulsed magnetic field meter based on an RL integrator to the low-frequency region.Введение. В некоторых областях современной науки и техники необходимо проводить измерения амплитудно-временных характеристик импульсного магнитного поля. Такие измерения проводят при испытаниях на стойкость к импульсному магнитному полю, при этом длительность фронта импульса магнитного поля составляет сотни наносекунд, а длительность импульса до полуспада – сотни микросекунд.Цель работы. Разработка измерителя напряженности магнитного поля, обладающего линейной характеристикой преобразования, позволяющего проводить измерения длительности фронта, длительности импульса до полуспада и пикового значения напряженности импульсного магнитного поля.Материалы и методы. Для измерения параметров импульсного магнитного поля существует несколько методов, в данной статье выбран индукционный метод. Для получения сигнала, пропорционального напряженности импульсного магнитного поля, сигнал с индукционного преобразователя интегрируют с использованием самоинтегрирующего индукционного преобразователя (RL-интегрирование) или при помощи внешнего RC-интегратора. Первый способ показывает хорошие результаты при измерении сигналов длительностью сотни наносекунд, однако дает плохой результат при измерении параметров более длинных импульсов. Второй способ применяют для определения параметров сигналов длительностью сотни микро- и миллисекунд, данный способ дает большую погрешность при измерении параметров сигналов длительностью сотни наносекунд и меньше. Последовательное использование двух способов интегрирования приводит к возникновению дополнительной погрешности измерения длительности импульса до полуспада.Результаты. Разработано устройство, которое позволило при помощи измерителя импульсного магнитного поля на основе RL-интегратора определять требуемые параметры импульса магнитного поля с относительными погрешностями 10, 10 и 9 % соответственно. Данное устройство устраняет ошибку, вызванную потерями в активном сопротивлении индукционного преобразователя, что позволяет провести измерение длительности импульса до полуспада без дополнительных погрешностей в условиях, когда длительность фронта импульса составляет сотни наносекунд, а длительность спада импульса – сотни микросекунд.Заключение. Разработка функционального преобразователя позволила расширить частотную характеристику измерителя импульсного магнитного поля на основе RL-интегратора в область низких частот
