Introduction. Milk has a high nutritional value and is a vital component of human diet. Today, the dairy market is one of the largest and actively developing food markets. However, this industry is characterized by such problems as seasonality and poor transportability of raw materials. These problems particularly affect small farms. Deep processing of dairy raw materials to obtain dry powders is the most effective way to solve these problems. The research objective was to develop a low-tonnage dryer for producing milk powder on small farms and to select the optimal drying temperature. Study objects and methods. The research featured whole milk of the ‘Svoya Ferma’ brand, mass fraction of fat = 3.4–4.5%. The research was performed on the premises of Kemerovo State University (Kemerovo, Russia). The milk was dried on a pilot sample of the roller dryer developed by the research team. The dryer consisted of a vessel, heating drums, and a microcontroller, which was connected to the temperature sensor and the control circuit of the power part, which had a powerful rectifier and pulse regulator. Results and discussion. When the drying temperature exceeded 98°C, the characteristics of the milk powder deteriorated, and the milk failed to meet the State Standard. The optimal drying temperature was 92–95°C, since at this temperature all the characteristics, except for the solubility index, corresponded to the State Standard. The sensory and physical properties of the milk powder were improved by reducing the drying time and the distance between the knife and the drum. Conclusion. Further experiments have to be performed to determine the optimal rotation speed of the drums and the distance between the knife and the drum.

Complete utilization of all wastes of fish processing becomes actual in modern conditions of depletion of the fish raw materials because of the commercial catch decreasing in the Volga-Caspian Basin. Abilities of fish oil extraction from fins of catfish are considered. Several technologies of the oil extraction from this waste are tested: thermal, carbamide-thermal, combined carbamide-thermal, and hydromechanical. Organoleptic parameters of the raw materials and produced fatty products are determined in accordance with the state standard № 7631-2008. Water, protein, fat, and mineral substances content in the raw material and physical and chemical properties of the produced fish oil are measured by standard methods given in the state standard № 7636-85, using the thin-layer chromatography. The fat content in the raw material is evaluated as 33.8 %. The fish oil output from the fat-containing raw materials is determined. The carbamide-thermal method is defined as the optimal one for oil extraction from fins of catfish. At the first stage, the raw material is heated to 70 о C during 60 minutes, then it is mixed with 1.5 % of carbamide in 30 % solution and the liquid and dense fractions of the mixture are separated under 3000 rpm in 30 minutes; at the second stage, the dense fraction is heated to 70°C, mixed with 20 % of water, and the mixture is heated to 75 о C during 60 min, then the liquid and dense fractions of the mixture are separated again; finally, the liquid fractions from both stages of treatment are subjected to sedimentation during 10 minutes under ambient temperature and the semi-finished fatty products are separated by 15 min. centrifuging at 4000 rpm. Phospholipids, monoglycerides, sterols, hydrocarbons, sterol esters, and the main fractions of triglycerides and carotenoids are presented in the fish oil produced with this technology, so it could be used in veterinary. This method for fish oil extraction from the fins of catfish is applied to the enterprises Parshikov and Fabrika Vesna and showed its efficiency in industrial conditions.

Bamboo is a lightweight and high-strength raw materials that encouraged researchers to investigate and explore, especially in the field of biocomposite and declared as one of the green-technology on the environment as fully accountable as eco-products. This research was to assess the technical feasibility of making single-layer experimental Medium-Density Particleboard panels from the bamboo waste of a three-year-old (Dendrocalamus asper). Waste materials were performed to produce composite materials using epoxy resin (C21H25C105) from a natural treatment by soaking with an average of pH 7.6 level of sea-water. Three different types of MDP produced, i.e., bamboo waste strip MDP (SMDP), bamboo waste chips MDP (CMDP) and bamboo waste mixed strip-chips MDP (MMDP) by following the same process. The experimental panels tested for their physical-mechanical properties according to the procedures defined by ASTM D1037-12. Conclusively, even the present study shows properties of MDP with higher and comparable to other composite materials; further research must be given better attention as potential substitute to be used as hardwood materials, especially in the production, design, and construction usage.

The pressures encountered by hospitals in the current era of reimbursement declines and stiffened competition are well known. As the “ultimate” payors—primarily employers and government—aggressively continue to seek low cost care, the response of the hospital industry has been to move toward consolidation and efficiency-enhancing mechanisms.Increasingly, nonprofit, tax-exempt hospitals have come to believe that they are at a significant disadvantage vis-á-vis their for-profit brethren in their ability to attract the capital needed to compete in the market. A growing trend among nonprofit hospitals, therefore, is to sell to or enter into a joint venture with a proprietary organization, or alternatively to convert to for-profit status. In 1995, fifty-eight nonprofit hospitals became for-profit; hospital conversions to for-profit status in 1996 are projected to outstrip the pace established the prior year.The conversion trend has not gone unnoticed at the state level. Recently, several states have proposed or enacted laws regulating sales and conversions of nonprofit hospitals, and many more states are contemplating such legislation.

The high cost of development and raw materials have been obstacles to the widespread use of titanium alloys. In the present study, the high-throughput experimental method of diffusion couple combined with CALPHAD calculation was used to design and prepare the low-cost and high-strength Ti-Al-Cr system titanium alloy. The results showed that ultra-fine α phase was obtained in Ti-6Al-10.9Cr alloy designed through the pseudo-spinodal mechanism, and it has a high yield strength of 1437 ± 7 MPa. Furthermore, application of the 3D strength model of Ti-6Al-xCr alloy showed that the strength of the alloy depended on the volume fraction and thickness of the α phase. The large number of α/β interfaces produced by ultra-fine α phase greatly improved the strength of the alloy but limited its ductility. Thus, we have demonstrated that the pseudo-spinodal mechanism combined with high-throughput diffusion couple technology and CALPHAD was an efficient method to design low-cost and high-strength titanium alloys.

Abstract Developing photovoltaic materials with simple chemical structures and easy synthesis still remains a major challenge in the industrialization process of organic solar cells (OSCs). Herein, an ester substituted poly(thiophene vinylene) derivative, PTVT-T, was designed and synthesized in very few steps by adopting commercially available raw materials. The ester groups on the thiophene units enable PTVT-T to have a planar and stable conformation. Moreover, PTVT-T presents a wide absorption band and strong aggregation effect in solution, which are the key characteristics needed to realize high performance in non-fullerene-acceptor (NFA)-based OSCs. We then prepared OSCs by blending PTVT-T with three representative fullerene- and NF-based acceptors, PC71BM, IT-4F and BTP-eC9. It was found that PTVT-T can work well with all the acceptors, showing great potential to match new emerging NFAs. Particularly, a remarkable power conversion efficiency of 16.20% is achieved in a PTVT-T:BTP-eC9-based device, which is the highest value among the counterparts based on PTV derivatives. This work demonstrates that PTVT-T shows great potential for the future commercialization of OSCs.
