This research is based on the background of many banana slicing machines needed by home industries. Therefore, to increase production capacity, simplify work and shorten work time with optimum results new innovations are needed. The purpose of this study was to make a prototype of a banana slicing machine with variations in pulley diameter to the rotational speed and thickness of the slices and to know the capacity of the banana slicing machine. The prototype of a banana slicing machine made using a 1400 rpm electric motor is assembled with a 40 mm pulley, to reduce the v-belt rotational speed to pulley with a diameter of 125 mm pulley, 150 mm, 175 mm. The capacity of the first pulley slices at a speed of 448 rpm, the pulley diameter of 125 mm is 7.66 grams / second and the slice thickness is 2 mm. The sliced capacity of the second pulley uses a 150 mm pulley diameter of 6.42 grams / second and a slice thickness of 1-2 mm. The capacity of the third pulley slice uses a 175 mm pulley diameter of 5.51 kg / hour and a slice thickness of 1 mm and not a rule.

This study examines the feasibility of using high-porosity and conductive bamboo charcoal in electrophoretic deposition (EPD)-assisted polishing of silicon wafers and explored the influence of various parameters on surface roughness. EPD-assisted polishing with bamboo charcoal offers an alternative to the lapping process prior to CMP. According to the results, the best parameter combination obtained under the current experimental setting is machining time, 12 min; rotational speed of platen, 75 rpm; and voltage, 6V. EPD indeed contributes to more effective and efficient polishing, with better surface quality attained within a shorter machining time.

The article examines the state of production capacity of Russian industry. It is shown that in spite of certain positive shifts, the rate of technological modernization in recent years has been insufficient for marked progressive changes in the capacity structure and quality. In contrast to the industrial growth after the crisis of 1998 that took place in the presence of significant reserves of capacity, the current level of idle capacity is much lower. The lack of mass input of modern and high-tech industries objectively limits the possibilities of import substitution and economic growth.

Cellulose Composite

When pulp and minerals are co-processed in aqueous suspension, the mineral acts as a grinding aid, facilitating the cost-effective production of fibrils. Furthermore, this processing allows the utilization of robust industrial milling equipment. There are 40000 dry metric tons of mineral/microfbrillated (MFC) cellulose composite production capacity in operation across three continents. These mineral/MFC products have been cleared by the FDA for use as a dry and wet strength agent in coated and uncoated food contact paper and paperboard applications. We have previously reported that use of these mineral/MFC composite materials in fiber-based applications allows generally improved wet and dry mechanical properties with concomitant opportunities for cost savings, property improvements, or grade developments and that the materials can be prepared using a range of fibers and minerals. Here, we: (1) report the development of new products that offer improved performance, (2) compare the performance of these new materials with that of a range of other nanocellulosic material types, (3) illustrate the performance of these new materials in reinforcement (paper and board) and viscosification applications, and (4) discuss product form requirements for different applications.

Multiple Recycling

Paper for recycling is an important fiber source for the production of corrugated base paper. The change in production capacity toward more and more packaging papers affects the composition of paper for recycling and influences the paper quality. This research project investigated the influence of the multiple recycling of five different corrugated base papers (kraftliner, neutral sulfite semichemical [NSSC] fluting, corrugating medium, testliner 2, and testliner 3) on suspension and strength properties under laboratory conditions. The corrugated board base papers were repulped in a low consistency pulper and processed into Rapid-Köthen laboratory sheets. The sheets were then recycled up to 15 times in the same process. In each cycle, the suspension and the paper properties were recorded. In particular, the focus was on corrugated board-specific parameters, such as short-span compression test, ring crush test, corrugating medium test, and burst. The study results indicate how multiple recycling under laboratory conditions affects fiber and paper properties.

Good Agricultural Practice

Heterodera schachtii Schmidt, 1871 is one of the most economically important pests of sugar beet (Beta vulgaris L.) worldwide. It is also widespread in most sugar beet growing regions in Ukraine causing serious yield reduction and decreasing sugar content of sugar beet in infested fi elds. An advanced parasitic strategy of H. schachtii is employed to support nematode growth, reproduction and harmfulness. In intensive agriculture systems the nematode control measures heavily rely on nematicides and good agricultural practice (crop rota- tion in the fi rst place). But alternative strategies based on nematode resistant sugar beet cultivars and hybrids are required as none of nematicides approved for the open fi eld application are registered in Ukraine. Here we review the achievements and problems of breeding process for H. schachtii resistance and provide the results of national traditional breeding program. Since the beginning of 1980s fi ve sugar beet cultivars (Verchnyatskyi 103, Yaltuschkivska 30, Bilotcerkivska 45, BTs-40 and Yuvileynyi) and seventeen lines partly resistant or toler- ant to H. schachtii have been obtained throughout targeted crossing and progenies assessment in the infested fi elds. The further directions for better utilization of genetic sources for nematode resistance presented in na- tional gene bank collection are emphasized. There is a need for more accurate identifi cation of resistance genes, broader application of reliable molecular markers (suitable for marker-assisted selection of nematode resistant plants in the breeding process) and methods for genetic transformation of plants. Crop cash value and national production capacity should drive the cooperation in this fi eld. Knowledge as well as germplasm exchange are thereby welcomed that can benefi t breeding progress at national and international level.
