Published: January 2020

Oil palm empty fruit bunches (OPEFB) are the waste of palm oil processing and lignocellulosic biomass that can be used as raw material for xylitol production. In this research, bioconversion of xylitol using the Simultaneous Saccharification and Fermentation (SSF) process in one reactor with a short time and could save the cost. Pretreatment requires to degrade the lignin compound with thermal pretreatment. Hydrolysis of OPEFB performs enzymatically by commercial xylanase enzyme that is Cellic Htec2 and continued with fermentation by yeast Debaryomyces hansenii. The research used experimental and descriptive analysis that covers of variation of OPEFB substrate concentration (7.5%, 10%, 15%, 20%) on specific growth rate (µ), the yield of xylitol and substrate utilization. The results showed that an increase of OPEFB substrate concentration affected by the increase of specific growth rates  (μ) are 0.091/h, 0.094/h, 0.095/h and 0.126/h. It also affected to the decreasing of xylitol yield on 42 hours fermentation are 0.201 g/g; 0.189 g/g; 0.170 g/g; and 0.104 g/g.

Published: January 2020

Today, the fuel and energy complex (FEC) is the basis of Russian economy. It includes the most dynamically developing industries, such as petrochemical, oil refining, etc., associated with the production, transportation and processing of various fuels, as well as industries engaged in the production and distribution of electricity: thermal engineering, hydropower engineering and nuclear power engineering. The nomenclature of FEC centrifugal pumps includes a wide list of names: singleand multistage centrifugal pumps of low, medium and high pressure for clean water, water with impurities and various aggressive media [1, 2], pumps for oil production and transportation (trunk, booster, electric centrifugal production pumps, pumps for pumping leaks, etc.) and special pumps used in oil refining (cracking, cantilever chemical, etc.) [3]. The development of technical solutions aimed at improving energy efficiency as well as reliability and durability is one of the trends in the development of centrifugal pumps FEC that are most widely covered in engineering literature [4.9]. Along with this, reducing the complexity and cost of production of these pumps due to the automation of the design process remain just as important. In the given article, questions of development of a method of automated profiling of components of flow passage of centrifugal pumps for needs of FEC are considered. The description of the proposed method and the results of its approbation on the example of profiling of the flow passage of the impeller of the centrifugal cantilever chemical pump AH 12.5/50 are presented. Comparison with other known methods is carried out. The estimation of time costs for design works is carried out. It has been found that the automated profiling of the flow passage of the impeller according to the presented method took 720 times less time than manual profiling using conventional methods.

Published: January 2020

A survey has been held of a BG-2600 natural draft cooling tower of thermal power plants, in the reduced hydraulic load mode. The technical condition of the reinforced concrete tower, the skeleton frame, the irrigation device, the water distribution system and the air duct windows has been inspected. Defects of the cooling tower structural elements have been identified. These include: horizontal sagging of the irrigation device, considerable gaps between its blocks and their partial destruction, problems with nozzles and structures of air duct windows. The identified defects are attributed to the causes of irregular water and air flows. The degree of irregularity of irrigation density and air flow in the tower has been estimated. Over the cross-section of the tower, a significant standard deviation from the average value or irregularity of irrigation density (30%) and irregularity of air flow (23.5%) has been established. The temperature and cooling curves of the cooling tower have been plotted taking into account irregularities of irrigation density and air flow rate. Normal and defective sections of the cooling tower have been identified based on working characteristics. Standard characteristics of the BG-2600 cooling tower have been plotted based on a nomogram. A comparative analysis of the working and standard characteristics has been held. The degree of influence produced by irregularities in water and air flows on the cooling process has been established. It has been found that the established irregularities in water and air flows result in a decrease in the temperature difference on average by 2°C and a decrease of cooling capacity by 7.3 Mcal/m2∙hr with a hydraulic load of 8840 m3/h. The results indicate a significant impact produced by irregularities of flows on cooling effect. The tasks to eliminate irregularities in distribution of flows as well as to increase the tower cooling efficiency have been formulated.
Improving the efficiency and reliability of electric power generation at incineration plants
Authors: Martynov A. V. , Kutko N. E.
Published: January 2020

The article deals with the problem of waste disposal and, accordingly, landfills in the Moscow Region, which have now become the number 1 problem for the environment in Moscow and the Moscow Region. To solve this problem, incineration plants (IP) will be established in the near future. 4 plants will be located in the Moscow Region that will be able to eliminate 2800 thousand tons of waste per year. Burning of waste results in formation of slag making 25% of its volume, which has a very high temperature (1300.1500°C). An arrangement is considered, in which slag is sent to a water bath and heats the water to 50.90°C. This temperature is sufficient to evaporate any low-temperature substance (freons, limiting hydrocarbons, etc.), whereupon the steam of the low-temperature working medium is sent to a turbine, which produces additional electricity. The creation of a low-temperature thermal power plant (TPP) increases the reliability of electricity generation at the IP. The operation of low-temperature TPPs due to the heat of slag is very efficient, their efficiency factor being as high as 40.60%. In addition to the efficiency of TPPs, capital costs for the creation of additional devices at the IP are of great importance. Thermal power plants operating on slag are just such additional devices, so it is necessary to minimize the capital costs of their creation. In addition to equipment for the operation of TPPs, it is necessary to have a working medium in an amount determined by calculations. From the wide variety of working media, which are considered in the article, it is necessary to choose the substance with the lowest cost.

Published: January 2020

Fires and accidents at nuclear power facilities that occurred in the past resulted in considerable property damage, both direct and indirect one. The emerging threats had a negative impact on the fire-fighting process that had to be interrupted, which contributed to spreading of fire. One way of solving the problem is to develop and use robotics, and in order to achieve the effectiveness of robotics equipment, this must be designed taking into account the specifics of the facility, where it is planned to be used, and operate throughout the plant premises, while being of the light class. Having analyzed the peculiarities of origination and development of fires at NPPs, as well as taking into account the specifics of the facility, technical requirements for the design of the robotic equipment were developed, which formed the basis for the creation of a prototype implemented in a mobile robotic fire-fighting unit (MRUP). In order to check the stated tactical and technical characteristics, MRUP was subjected to tests for its running performance, operability of its components and assemblies, and fire-extinguishing properties. The test of running performance was carried out on dedicated stands with a variety of inclined surfaces, climbing angles and heights. For MRUP firefighting efficiency to be tested, a model hotspot was extinguished, the range of delivery and the consumption of fire-extinguishing agents were measured.

Three endemic Aphaenogaster from the Siculo-Maltese archipelago and the Italian Peninsula: part of a hitherto unrecognized species group from the Maghreb? (Hymenoptera: Formicidae: Myrmicinae)
Authors: Alicata Antonio , Schifani Enrico
Published: January 2020

More than 100 years ago, the Italian myrmecologist Carlo Emery described two endemic Sicilian ants: Aphaenogaster sicula Emery, 1908, which he originally considered a subspecies of A. crocea André, 1881, and A. fiorii Emery, 1915 stat. nov., which he believed was a subspecies of A. gibbosa (Latreille, 1798). Males of the two species and the queen of A. fiorii were never described. The scarcity of information contained in the original description led to several misunderstandings by subsequent authors: for example, A. sicula was later elevated to species-rank on the basis of misidentified material of A. fiorii stat. nov. We redescribe the two species, adding the descriptions of their missing castes and designating their lectotypes. We also describe a third related species of the genus: A. trinacriae sp. nov. from Sicily. The ecology and distribution of the three are illustrated. Their relationship with the other congeneric species of the Mediterranean basin is discussed considering the morphology of all three castes, with attention to the often-overlooked males. Despite the fact that A. fiorii and A. sicula were lately believed to be close relatives of A. subterranea (Latreille, 1798), the morphological elements available suggest that they probably belong to a separate, hitherto unrecognized clade from the Maghreb (North-Western Africa), together with A. trinacriae sp. nov.

Authors: Yasunaga Tomohide , Tamada Yui , Hinami Haruka , Miyazaki Ayana , Duwal Ram Keshari , Nagashima Tetsuya
Published: January 2020

Asian genera and species of the plant bug tribe Hallodapini are reviewed. The present classification system is based particularly on detailed morphology and function of the stridulatory device and concealed habitat preference. Our recent efforts successfully demonstrated that the stridulatory devices of the forewing edge and dorsal metafemur are doubtlessly used for intraspecific communication (at least for courtship behavior). Based on the stridulatory structures and additional characters, Cleotomiris Schuh, 1995, Cleotomiroides Schuh, 1984, Hallodapus Fieber, 1858 and Wygomiris Schuh, 1984, are re-diagnosed and discussed; Alloeomimella Yasunaga & Duwal gen. nov. is proposed to accommodate Alloeomimus muiri Schuh, 1984 and a new combination, Alloeomimella muiri (Schuh) comb. nov., is accordingly established. Six new species are further described: Cleotomiroides ishikawachui Yasunaga & Duwal sp. nov. (Indonesia: Java); Hallodapus jingfui Yasunaga & Duwal sp. nov. (Taiwan); H. spinosus Yasunaga & Duwal sp. nov. (Thailand); H. susurratus Yasunaga & Duwal sp. nov. (Thailand); Wygomiris paveli sp. nov. (Taiwan); and W. phormictes sp. nov. (Taiwan). The male of Wygomiris nanae Yasunaga, 2012 is reported for the first time. A teratological form found on the antennae in two Wygomiris species is also documented.

Three new species of Diptera (Sphaeroceridae: Limosininae) from the Madeira Island (Portugal), viz. Spelobia polymorpha sp. nov., Pullimosina (Pullimosina) kesoni sp. nov., and P. (P.) dorae sp. nov. are described (both sexes), illustrated and their relationships, biology and distribution discussed. All these species are terricolous inhabitants of the leaf-litter stratum of the original Madeiran laurel forests (Laurisilva) and because of their poor flying ability they are considered endemic to Madeira. None of these species have relatives among endemic species of Sphaeroceridae known from other Macaronesian archipelagos inasmuch as the endemic species of Canary Islands and Azores belong to different genera of Limosininae.

The harlequin ladybird, Harmonia axyridis (Pallas, 1773), is native to Asia but has been introduced to many countries, both intentionally and unintentionally. In the Middle East region, H. axyridis was so far only known from Iran and Turkey. This study reports H. axyridis for the first time from a country with a hot desert climate, Saudi Arabia. The single specimen that was found is most likely the result of unintentional release. Successful spreading of H. axyridis in Saudi Arabia will be limited because of high temperatures during summer and scarcity of prey (aphids). New records from Iran and Turkey suggest fast spreading of H. axyridis in these parts of the Middle East. In addition, we also present new records from Iran and Turkey for H. quadripunctata (Pontoppidan, 1763), the other species in the genus that occurs in the Middle East region. A key and illustrations are provided for both species.

Discovery of the genus Airaphilus (Coleoptera: Silvanidae) in Japan, with a description of a potentially endangered new species
Authors: Yoshida Takahiro , Halstead David G. H. , Hirowatari Toshiya
Published: January 2020

The genus Airaphilus Redtenbacher, 1858 (Coleoptera: Silvanidae: Silvaninae) is recorded from Japan for the first time. The record is based on the discovery of a new apterous species, Airaphilus abei sp. nov., described and illustrated herein. The new species is similar to Airaphilus filiformis (Rosenhauer, 1856), however it can be distinguished by long antennae reaching about body midlength; anterior margin of pronotum about as wide as head; elytra without a humeral tooth, rounded to base and more to apices; and long metaventrite. Only five specimens have been found and these were collected in 1992 at Kokeyachi bog in the far north of Honshu. This bog and the adjacent wetlands have begun to dry out and are undergoing a transition to grassland. These factors, together with the apparently very limited distribution and the possibly restricted mobility due to lack of hind wings, suggest that at least in this locality the new species may be endangered.

Taxonomic notes on the rare ant genus Chrysapace with description of a new species from Brunei (Hymenoptera: Formicidae: Dorylinae)
Authors: Yamada Aiki , Lin Chung-Chi , Eguchi Katsuyuki
Published: January 2020

The genus Chrysapace Crawley, 1924 is one of the rarest and poorly known lineages in the ant subfamily Dorylinae, currently composed of only three extant valid species from the Oriental Realm. There is some taxonomic obscurity concerning the distinction between two of the three valid species, C. sauteri (Forel, 1913) and C. costatus (Bharti & Wachkoo, 2013), resulting from previous unavailability of C. sauteri type material and inconsistency in descriptions provided in previous literature. In the present study, we examined the C. sauteri syntype and the C. costatus holotype as well as newly collected material and vouchers used in previous literature. Although both of the species agreed well with each other in most morphological characters of the worker, we tentatively retain the separation of these species based on differences in the head sculpture, eye and ocelli sizes. The worker, queen, and male of C. sauteri, and the worker of C. costatus are here redescribed with the first provision of COI DNA barcode data. In addition, C. merimbunensis Yamada & Eguchi sp. nov. is described from Brunei based on workers and males from a single colony. A key to valid Chrysapace species is also provided.

(Afroblepharida Biondi & D’Alessandro, 2017), and places the new species within Afroblepharida, even though with a moderate support.
A new subterranean Crematogaster with one ommatidium from Cambodia, based on morphology and DNA (Hymenoptera: Formicidae)
Authors: Hosoishi Shingo
Published: January 2020

A subterranean myrmicine ant Crematogaster monocula sp. nov. is described based on two worker specimens from Cambodia. This species belongs to the C. biroi group of the subgenus Orthocrema Santschi, 1918, which is characterized by developed subpetiolar process, developed subpostpetiolar process and sculptured mesosoma. The new species is easily distinguished from other species of Crematogaster Lund, 1831 by having only one ommatidium. DNA sequences comprising a 761 bp fragment of the 3’ region of the mitochondrial COI gene were amplified and analyzed for C. monocula sp. nov. and other closely related species from the same group. The interspecific COI divergence is 17.8% for C. monocula sp. nov. and C. reticulata Hosoishi, 2009. This species is unique in having the smallest eye in the genus Crematogaster.
