ABSTRACT Brazilian market of potato processing has presented expressive development in recent years. However, its expansion is constrained by raw material supply suitable for industrial processing. Selection of adequate cultivars contributes to final product cost reduction as well as its yield and quality improvement. The research aimed to study tuber yield and evaluate its frying potential for shoestrings and chips, of potato cultivars recently introduced in Brazil. Nine potato cultivars (Arizona, Caruso, Destiny, Excelence, Saviola, Agata, Almera, Fontane and Markies) were assessed in an experiment carried out between January and May, 2013, in South-West region of Minas Gerais State, Brazil. 'Arizona' and 'Caruso' cultivars exhibited superior productive potential and along with 'Markies' the highest production of marketable tubers. 'Caruso' and 'Destiny' produced more than 20% of dry matter and the lowest reducing sugar levels. 'Caruso' exhibited the highest frying yield in both processing shapes and absorbed less fat as shoestring. 'Destiny' absorbed less fat when processed as chips. 'Excelence' presented intermediary performance for every evaluated attribute. 'Caruso', 'Destiny', and 'Excelence' produced chips with appropriate color for market. Among the assessed cultivars, 'Caruso', 'Destiny', and 'Excelence' were the most promising. These cultivars demonstrated appropriate processing ability in the shape of shoestrings. 'Destiny' could also be indicated to be processed as chips.

Brazil is the world's largest producer of sugarcane, the main raw material used for the production of alcohol and sugar. The crop to achieve good levels of productivity demands high amounts of nutrients, which are usually supplied by the use of mineral fertilizers. An alternative for efficient fertilization is through the use of organomineral fertilizers. Such fertilizers consist of the mixture of organic fertilizers of animal or vegetable origin, and mineral fertilizers that undergo industrial processing. The industrial advance associated with the population increase has generated a large amount of solid waste and wastewater. One way to reduce the effects of environmental pollution from the presence of these solid wastes is through their treatment, giving rise to a pasty material, known as sewage sludge. Sewage sludge presents the potential to be used in the mineral nutrition of plants, both as fertilizer and as a soil conditioner. Biostimulants are natural or synthetic substances that can be applied directly to plants to increase yield and quality of crops of economic interest. Thus, the present review aims to report the study on the use of organomineral fertilizers from sewage sludge and biostimulant in sugarcane cultivation.

A brief review of the state of collection, disposal and processing of used oils shows the availability of their resource in the country and the main trends in the organization of qualified collection, disposal and processing according to the lubricating oil version. The relevant technologies are given for individual stages and in general for enterprises, the choice of which depends on the quality and characteristics of raw materials. The advantage of the technological scheme, including coagulation purification at the stage of raw material preparation and vacuum distillation with the selection of distillate fractions and the residue, followed by additional purification of the residue, is shown. The use of this technology makes it possible to increase the yield and quality of the target product, which is practically impossible for the raw materials currently available in the Russian Federation using other technologies.

Based on the late medieval leather artefacts from Puck, Gniew, Lębork and Chojnice, an attempt was made to assess the level of shoemaking production at that time. Microscopic analyses of leather goods and production waste proved that in the field of tanning the activities related to the mechanical treatment of leather were carefully performed, although with insufficient professional knowledge concerning the process. The results of the identification of the animal origin of the leather confirmed the purposeful selection of raw material with different properties for individual footwear elements and the ability to properly cut it. The quality of the shoemaking products was highly rated in terms of technology and style. However, in the analysed collections a clearly perceptible difference in craftsmanship and assortment of products from Gniew and the other three towns was noticed.

The aim of this study was to determine the effect of differentiated air relative humidity during the drying process on selected quality features of TSG (traditional specialties guaranteed) pork and poultry-pork kabanosy. After heat treatment and 24-hour cooling at 4–6°C, the products were placed in three chambers at 15°C with differentiated air relative humidity: 60, 70, and 80%, respectively. The drying process was carried out until all variants of kabanosy achieved the required final yield of the product (<68%). Color components, water activity and shear force, water, protein, fat, and salt content, and the TBARS indicator values were determined. The drying process might be shortened (~50%) by a reduction of humidity in the drying chamber from 80 to 60%. The changes in the content of chemical components in pork kabanosy compared to poultry-pork ones demonstrated the different dynamics of the drying of the two types of kabanosy and the need for the selection of optimum drying conditions relative to raw material composition.

Productivity of use of technique for statistical estimation of virusfree clonal lines at improvement of potato varieties was overviewed. It was shown, that application of the given technique can considerably improve the quality of initial material at sanitation of potato cultivars by biotechnological methods at the expense of selection of highly productive virus-free lines without deviations from the initial phenotype.

Yield and quality of seed- and vegetatively-propagated rhubarb [Rheum rhabarbarum L.) for annual production were evaluated for 4 seasons. Field planting of transplants or crown divisions in late October or early November resulted in harvests beginning in early to late January and continuing until late April. Selection of `Victoria' seedlings based on petiole color was not effective in increasing the proportion of red mature petioles. Yields from seed-propagated annual `Victoria' rhubarb were always higher than yields from `McDonald' single-bud crown divisions and higher than yields from `McDonald' crown-divisions in one of two years. The four-year average yield for `Victoria' seed-propagated rhubarb was 20.4 Mg·ha-1 whereas `McDonald' crown-division-propagated rhubarb had a two-year average yield of 15.8 Mg·ha-1. On the other hand, petiole color of vegetatively-propagated rhubarb was always superior to that of seed-propagated rhubarb. GA applications increased early yield from `McDonald' single-bud divisions, but reduced early and total harvest petiole weight.

In Bosnia and Herzegovina, Montenegro, as well as in most Balkan countries, wool is a major environmental problem. After sheep shearing, farmers usually leave the wool at the shear sites, providing poorly degradable organic waste. The purchase price of such untreated wool is as low as its quality. By this research, we have tried to draw attention, from another aspect, to the quality of wool fibers of certain parts of the body, which is ultimately very important in the textile industry and in the selection of wool for further processing. The cuticle is made from cornfied cells, flakes, located on the surface of wool fibers. One of the significant roles of the cuticle is the protective. Namely, the cuticle protects the wool fibers from various external factors, whether mechanical or physic-chemical (such as ammonia evaporation in poorly maintained facilities, etc.), which can damage the fleece and thus make it less quality. We have found some differences in the flakes position and shape in the wool fibers we investigated, depending on part of the body from which they were sampled. However, by microscopic analyses of samples taken from the root of the tail, we have found that the flakes were much smaller and finer in structure than the arrangement and appearance of the cornified flakes from the rump. In this study, we have compared the appearance and arrangement of flakes of cuticle, which is very important in assessing the quality of wool and its further use as a raw material.
