Design, characterisation and validation of a haptic interface based on twisted string actuation.

This paper presents the design and experimental characterisation of a wrist haptic interface based on a twisted string actuator. The interface is designed for controlled actuation of wrist flexion/extension and is capable of rendering torque feedback through a rotary handle driven by the twisted string actuator and spring-loaded cable mechanisms. The interface was characterised to obtain its static and dynamic haptic feedback rendering capabilities. Compliance in the spring and actuation mechanism makes the interface suitable for smooth rendering of haptic feedback of large magnitudes due to the high motion transmission ratio of the twisted strings. Haptic virtual wall rendering capabilities are demonstrated

Influence of probiоtic additive “Evitalia” on growth and blood indices of quails

The results of the studies on the determination of the optimal dose of the probiotic additive “Evitalia” (PAE) for the quails of the Texas breed have been presented in the article. The experiments were conducted on the quails aged 1–35 days. The object of the research was the probiotic additive “Evitalia” that consisted of eight components (the strains of lactic acidmicroorganisms, macro- and microelements). The subject of the investigation was the influence of PAE on the growth, preservation, the morphological composition and biochemical indices of blood. The studies were carried out in the following conditions of microclimate and sanitary regime: the air temperature in the pens-cages was 16–18 ºC in the autumn and winter period that was 5–7 ºC lower than it was provided by the standard; in spring the temperature was 23–15 ºС that was lower than it was provided by the standard (29–35 ºС). The concentration of carbon dioxide ranged within 0.20–0.25 % (2.0–2.5 l/m3), ammonia – 12–13.4 mg/m3, the general contamination of the air by microflora was 50–60 thousand KOE/m3. The experiments were conducted on the four groups of quails, 60 quails in each group. The quails of the control group were fed by water without PAE, the probiotic at the dose of 7 mg/500 ml of water was given to the quails of the experimental group 1 (E-1), 9 mg of probiotic/500 ml water received the birds of the experimental group 2 (E-2) and the quails of the experimental group 3 (E-3) were given the probiotic at the dose of 11 mg/500 ml water. The positive influence of the probiotic additive “Evitalia” on the growth and the body live weight gain of the quails was observedin the experimental groups as compared to the quails of the control group. The trustworthy increase in the growth and live weight gain of the quails was detected on the 7-, 14-, 21-, 35-day of their life (Р < 0.05), especially in the quails that received PAE at the dose of 9 mg (E-2). The quails of the experimental group 2 exceeded the others by the average daily live weight gains. The growth intensity of the quails in the experimental group 2 was 6.43 % higher than that of the control one, higher by 3.47 % and 5.57 % than in the experimental groups 1 and 3, respectively. The preservation of the quails in the control group was lower by 4.8 – 5.1 % as compared to the quails in the experimental groups. By the data on the growth of the body live weight, the composition and biochemical indices of blood of the quails it can be concluded that the optimal dose of the probioticadditive “Evitalia” is 9 mg/500 ml water that activates hematopoesis and stimulates the growth and development of quails

Innovations and support for quality in agriculture : a case study

The aim of the article is to investigate the economic and legal aspects of integrating innovations in agriculture and supporting the quality of agricultural products in the context of modern Russia. Throughout the process of research, the authors analyzed the directions of agricultural sector development, mechanisms of quality and safety support, as well as customer rights protection. As a result the authors have agreed on, the need to integrate cluster models in the agricultural sector, notably in the bee-keeping, seed production (including financing of this activity), as well as legislative stimulus to shift towards «green» biotechnology in the domestic agriculture. Based on the research conducted, the authors have proposed mechanisms to improve the current Russian legislation in the spheres of innovation development and support for quality and safety of agricultural production.peer-reviewe

Cerebellar anaplastic astrocytoma in adult patients: 15 consecutive cases from a single institution and literature review

Adult cerebellar anaplastic astrocytomas (cAA) are rare entities and their clinical and genetic appearances are still ill defined. Previously, malignant gliomas of the cerebellum were combined and reviewed together (cAA and cerebellar glioblastomas (cGB), that could have possibly affected overall survival (OS) and progression-free survival (PFS). We present characteristics of 15 adult patients with cAA and compared them to a series of 45 patients with a supratentorial AA (sAA) in order to elicit the effect of tumor location on OS and PFS. The mean age at cAA diagnosis was 39.3 years (range 19–72). A history of neurofibromatosis type I was noted in 1 patient (6.7%). An IDH-1 mutation was identified in 6/15 cases and a methylated MGMT promoter in 5/15 cases. Patients in study and control groups were matched in age, sex and IDH-1 mutation status. Patients in a study group tended to present with longer overall survival (50 vs. 36.5 months), but the difference did not reach statistical significance. In both cAA and supratentorial AA groups presence of the IDH-1 mutation remains a positive predictor for the prolonged survival. The present study suggests that adult cAA constitute a group of gliomas with relatively higher rate of IDH-1 mutations and prognosis similar to supratentorial AA. The present study is the first to systematically compare cAA and supratentorial AA with respect to their genetic characteristics and suggests that both groups show a similar survival prognosis

The potential of organic waste as a substrate for anaerobic digestion in Ukraine: trend definitions and environmental safety of the practices

This article is devoted to the analysis and prospects of using different types of organic waste to achieve environmental goals. Due to the unique climate and natural resources, Ukraine has significant potential for biomass, the processing of which should solve urgent problems with the disposal of waste, as well as the production of alternative energy sources and biofertilizers. The preferred substrates for anaerobic digestion in Ukraine, considering the technological feasibility, availability, and volume are animal manure (cattle, pigs), bird droppings, plant residues, industrial sludge, common sludges. After analyzing the statistics for 2015-2019, the groups of dominant wastes were identified, and with the help of the built-in function “TREND”, the forecast of the waste potential with an organic component for 2021–2026 was constructed. Examining the obtained indicators for different types of waste, the reasons for the tendency of decrease or increase in their formation in the next five years were revealed. The direction of enhancing the sustainability of bioenergy, achieving environmental goals through the bioprocessing of organic waste associated with the ecological safety of production processes were discussed

ПОЧВЕННО-ЗООЛОГИЧЕСКОЕ ОБСЛЕДОВАНИЕ АЛЛЮВИАЛЬНЫХ ТОРФЯНЫХ ПОЧВ, ЗАГРЯЗНЁННЫХ НЕФТЕПРОДУКТАМИ

The paper explores alluvial peat soil polluted by oil products and estimates the criteria of biological and agrochemical properties of peat soil. The paper reveals their being changed under the influence of oil products. The authors found out that oil products increased the toxicity of peat soils and reduced total exchange base and concentration of labile soil nutrients. This influenced negatively the number of the main groups of microorganisms. The cellulose-fermenting microorganisms were less resistant to soil pollution caused by oil products, their number was reduced in 6.1 times at weak form (from 78.7·104 to 13.0·104 ), strong formin 17.1 times (up to 4.6·104 ). The research found out that microscopic fungi appeared to be the most resistant to oil products; at weak form of pollution their number was reduced in 2.6 times (from 33.6·103 to 13.0·103 ); at strong form of pollution their number was reduced in 3.7 times (up to 9.0·103 ). The authors observed 655 soil organisms that belong to 17 species, 14 bloodlines and 6 orders. The springtails and Tenuipalpidae are mostly wide-spread in the investigated areas. Their high number was observed at the safe plots and the polluted ones. This certifies about their high plasticity and low resistance to soil pollution by oil products.На основании почвенно-зоологического обследования аллювиальных торфяных почв, загрязнённых нефтепродуктами, и оценки параметров биологических и агрохимических свойств выявлено их изменение под действием этого поллютанта. Установлено, что нефтепродукты значительно повысили степень токсичности торфяных почв, снизили в них показатель суммы обменных оснований и содержания подвижных форм элементов минерального питания. Всё это оказало неблагоприятное воздействие на численность основных групп микроорганизмов. Наиболее чувствительными к загрязнению почвы нефтепродуктами являлись целюллозоразлагающие микроорганизмы, они снизили свою численность при слабой её степени в 6,1 раза (с 78,7·104 до 13,0·104 ), при сильной степени – в 17,1 раза (до 4,6·104 ). Наименее чувствительными к нефтепродуктам оказались микроскопические грибы, они при слабой степени загрязнения снизили свою численность только в 2,6 раза (с 33,6·103 до 13,0·103 ), а при сильной степени – в 3,7 раза (до 9,0·103 ). Среди почвенных организмов в торфяных почвах было выявлено 655 особей, принадлежащих к 17 видам, 14 семействам и 6 отрядам. Наиболее широко распространенными на исследованных территориях (встречались на всех участках) оказались представители ногохвосток и плоские клещи. Их высокая численность не только на чистых участках, но и на подвергнувшихся загрязнению нефтепродуктами, свидетельствует об их высокой пластичности и малой чувствительности к загрязнению почвы этим поллютантом
