Recently, the increase in demand for rice has led to the numerous availabilities of rice husks (RH) in Malaysia. RH is being utilized as industrial fuel to generate electricity through incineration process in the boiler. During the incineration process, rice husk ash (RHA) is being produced as the by-product and caused environmental pollution. RHA has the potential of being utilized as organic fertilizer through a composting process to control environmental pollution. Thus, this study investigated the effect of different compositions on the duration of the composting process and physicochemical properties of compost. The raw materials and finished compost were analyzed in terms of elemental composition, pH, water holding capacity, and moisture content. The obtained results showed that addition of 7.5 wt.% of RHA can improve composting process due to the presence of silica which can maintain the moisture content within 50–60% and water holding capacity of compost at the range of 61-73%. The results of this study have clearly shown the potential of the compositing process in treating RHA. However, further studies are required to provide a deeper understanding of the mechanisms involved in facilitating the development of an optimum treatment system applicable to the industry.

Tilapia can be commercialised to produce sausages. However, the use of minced tilapia or tilapia surimi as the raw material and different mixing durations of the ingredients using the bowl cutter during the sausage production could affect the quality of the products. This study determined the effects of different mixing durations (10, 15 or 20 min) on the physicochemical, microstructural and sensorial properties of sausages made from minced tilapia and tilapia surimi. The washing of the minced tilapia during the surimi production significantly increased the tilapia surimi moisture content and pH, while reducing the protein, fat and ash contents. Subsequently, the addition of other ingredients to produce the sausages influenced the moisture, fat, ash and carbohydrate contents of both types of sausages. The type of raw material and mixing duration showed significant interactions in terms of linear expansion, water holding capacity and colour properties of the sausages. Individually, the tilapia surimi sausage had a better linear expansion, cohesiveness, colour and sensory acceptability than the minced tilapia sausage. The mixing times of 15 and 20 min produced better results for the physicochemical and sensory properties of both types of sausages. However, the gel strengths of both types of sausages were better when mixed for 15 min and the microstructure images supported this. Based on the results obtained, this study concluded that tilapia surimi as the raw material with 15 min of mixing duration is recommended to produce a better-quality sausage.

Применение протравливателей семян способствует повышению их полевой всхожести, снижению головневых заболеваний и корневых гнилей. Опыт эксплуатации протравливателей в зерносеющих хозяйствах показал, что в Российской Федерации наибольшее распространение получили самоходные протравливатели камерного типа ПС-20АМ01, Mobitox Super, ПСК-15. Недостатки этих машин выражаются в невозможности проведения качественного протравливания на площадках с углом наклона более 7 градусов и при работе машины при производительности в диапазоне от 60 до 100 от базовой. Кроме того, повышенные влажность семян после протравливания (по агротехническим требованиям АТТ не более 1 ) и дробление семян несколько снижают эффективность применения камерных протравливателей. Целью исследований являлось повышение качества протравливания семян за счет применения двухдискового распределяющего и двухуровневого отражающего устройств. Для чего сравнительные исследования протравливателя Mobitox Super, оснащенного двухдисковым распределяющим устройством и двухуровневым отражающим устройством семян, проводили с базовым вариантом Mobitox Super в ООО Русское поле Сердобского района Пензенской области на обработке семян озимой пшеницы Бирюза комбинированным инсектофунгицидным протравителем семян Селект Макс с нормой расхода препарата 1,7 л/т. Установлено, что в диапазоне от 30 до 150 мм открытия заслонки лепесткового дозатора разработанного камерного самоходного протравливателя качество протравливания семян значительно увеличивается в сравнении с серийно-выпускаемым Mobitox Super и увеличивается его производительность до 2,1 т/ч.The use of seed dressers improves their field germination, reduces smut diseases and root rot. The experience of the use of dressing agents in grain-sowing farms showed that the self-propelled seed dressers PS-20AM01, Mobitox Super, PSK-15 are most widely used in the Russian Federation.The disadvantages of these machines are expressed in the impossibility of conducting high-quality dressing on sites with an inclination angle of more than 7 degrees and when the machine is operating at a capacity in the range from 60 to 100 of the base. In addition, the increased moisture content of the seeds after dressing (according to the agrotechnical requirements of perfectly rigid body (PRB) - no more than 1 ) and the crushing of seeds somewhat reduce the effectiveness of using chamber dressers. The aim of the research was to improve the quality of seed dressing through the use of a two-disk distributing and a two-level reflecting devices. We conducted comparative studies of the Mobitox Super seed dresser, equipped with a two-disk distributor and a two-level seed reflector, with the basic version of Mobitox Super. The studies were carried out in the OOO Russkoye Polye of Serdobsky district of the Penza region on the treatment of winter wheat Biryuza seeds with a combined insectofungic seed dresser Select Max with a consumption rate of 1.7 l/t. It was established that in the range from 30 to 150 mm of opening the spade-type dispenser flap of the developed chamber self-propelled seed dresser, the quality of seed dressing significantly increased and its productivity increased to 2.1 t/h in comparison with the commercially available Mobitox Super.

The use of various types of neutralising materials in the cultivation of standard planting material of high-quality forest wood species has a significant effect on substrate acidity. Therefore, the study sets a goal to select peat substrates with different dosages of the neutralising component and determine their effect on the reaction of the peat substrate medium. The paper presents the results of the influence of neutralising materials of dolomitic meal and chalk of various doses with the use of mineral fertilisers. Dolomitic meal was used as a neutralising component, the pH of the peat substrate was 6.6 and chalk was 7.5. It was found that when neutralising a peat substrate created based on high-moor milled peat (pH 2.5) with the introduction of dolomitic meal in doses of 2-4 kg/m3 (European spruce), 3-4. 5 kg/m3 (Scots pine), optimal acidity can be achieved in a month. An increase in the concentration of lime material was recorded, which leads to an increase in the neutralisation of the substrate at a dose of 2.5 g and 3.0 g per 125 g of peat. The best indicators were demonstrated by options of doses of 1.5-2.5 g per 125 g of peat for 7-8 days of use and a dose of 3.0 g per 125 g of peat for 5-6 days compared with the control. An increase in the concentration of chalk in the neutralising material from 30% to 70% leads to a faster deoxidation of the substrate (pH 3.2), and an increase in the dosage of chalk increases substrate neutralisation. The electrical conductivity of the substrate at a dosage of 6-8 kg/m3 when applying chalk and dolomitic meal increases by 1.6-2.0 and 1.2-1.4 times, respectively. At the rate of application of 6-10 kg/m3, it has a lesser effect on the change in the electrical conductivity of the high-moor peat, and the introduction of dolomitic meal 2-4.5 kg/m3 into the milled peat during neutralisation does not lead to a change in the electrical conductivity of the peat. This data allows choosing neutralising materials of a certain concentration that will enable the cultivation of standard planting material of European quality and thereby ensure the proper quality of future stands

Abstract: Seeds with high quality are one of the important factors to consider in the crops establishment on field. Therefore, the physical and physiological quality of wheat seeds treated with mixes of micronutrients including zinc and protective products were aimed. The wheat seeds were analyzed in a factorial scheme 5x3x4, with five storage time: 0, 60, 120, 180 and 240 days; three micronutrients: micronutrients 1 (1% Mn; 0.1% Mo; 10% Zn); micronutrients 2 (0.3% B; 0.3% Co; 3% Zn) and no micronutrients, and four protective products: untreated seeds, polymer (Colorseed He), fungicide carboxin + thiram (Vitavax® Thiram 200 SC) + insecticide thiamethoxam (Cruiser® 350 FS) and polymer + fungicide + insecticide. After treatment, the seeds were stored under uncontrolled conditions for 240 days and at intervals of 60 days, the germination, accelerated aging and moisture content were determined. Wheat seeds untreated and treated with polymer have the best physiological performance during storage, regardless micronutrients treatments. The wheat seeds treated with carboxin + thiram + thiamethoxam and polymer + carboxin + thiram + thiamethoxam can be storage up to 120 days, under uncontrolled conditions, regardless micronutrients treatments. The seed treatment does not alter the moisture content of wheat seeds.

An experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during April 2013 to June 2013 to study the effect of three storage containers (tin container, polythene bag and cloth bag); and five storage periods (0, 15, 30, 45, and 60 days) on the seed quality of soybean. The experiment was laid out in Completely Randomized Design (CRD) with four replications. The soybean seeds stored in tin container showed maximum germination capacity with high germination index, highest seedling growth, seedling dry weight per plant and vigour index. The seeds stored in cloth bag had the lowest seed quality during the testing period. The highest 1000-seed weight, moisture content, electrical conductivity, abnormal seedlings and number of dead seeds were recorded in cloth bag; where the equivalent lowest values were recorded in tin container. The moisture content, 1000-seed weight, electrical conductivity, number of abnormal seedlings and dead seeds were increased with the longer period of storage. In addition, germination index, seedling growth, dry weight per plant of soybean seedling, and vigor index decreased with the increase in storage period. Among the three containers, tin container was the best and the cloth bag was the worst storage container for soybean seed storage for long period.

The main goal of this work was the increasing electrical conductivity of carbon-epoxy composites due to implementation of thermoplastic nonwoven veils doped with carbon nanotubes into the composite structure. Nonwovens which differ in areal weight were produced by extrusion of fibers and their thermal pressing. Laminates were fabricated using an out-of-autoclave method and nonwovens were incorporated between each layer of carbon-epoxy unidirectional prepreg. The applied conductive nonwovens improved surface and volume electrical conductivity of carbon fibre reinforced polymer in all directions. Microstructure observations proved a very high quality of the fabricated composites. The implementation of nonwovens affected the crack propagation under loading.
