The so-called vegetable milks are in the spotlight thanks to their lactose-free, animal protein-free and cholesterol-free features which fit well with the current demand for healthy food products. Nevertheless, and with the exception of soya, little information is available about these types of milks and their derivatives. The aims of this review, therefore, are to: highlight the main nutritional benefits of the nut and cereal vegetable milks available on the market, fermented or not; describe the basic processing steps involved in their manufacturing process; and analyze the major problems affecting their overall quality, together with the current feasible solutions. On the basis of the information gathered, vegetable milks and their derivatives have excellent nutritional properties which provide them a high potential and positive market expectation. Nevertheless, optimal processing conditions for each raw material or the application of new technologies have to be researched in order to improve the quality of the products. Hence, further studies need to be developed to ensure the physical stability of the products throughout their whole shelf-life. These studies would also allow for a reduction in the amount of additives (hydrocolloids and/or emulsifiers) and thus reduce the cost of the products. In the particular case of fermented products, the use of starters which are able to both improve the quality (by synthesizing enhanced flavors and providing optimal textures) and exert health benefits for consumers (i.e. probiotics) is the main challenge to be faced in future studies.

Research on the rectangle packing problems has mainly focused on rectangular raw material sheets without defects, while natural slate has irregular and defective characteristics, and the existing packing method adopts manual packing, which wastes material and is inefficient. In this work, we propose an effective packing optimization method for nature slate; to the best of our knowledge, this is the first attempt to solve the guillotine packing problem of rectangular items in a single irregular and defective slate. This method is modeled by the permutation model, uses the horizontal level (HL) heuristic proposed in this paper to obtain feasible solutions, and then applies the genetic algorithm to optimize the quality of solutions further. The HL heuristic is constructed on the basis of computational geometry and level packing. This heuristic aims to divide the irregular plate into multiple subplates horizontally, calculates the movable positions of the rectangle in the subplates, determines whether or not the rectangle can be packed in the movable positions through computational geometry, and fills the scraps appropriately. Theoretical analysis confirms that the rectangles obtained through the HL heuristic are inside the plate and do not overlap with the defects. In addition, the packed rectangles do not overlap each other and satisfy the guillotine constraint. Accordingly, the packing problem can be solved. Experiments on irregular slates with defects show that the slate utilization through our method is between 89% and 95%. This result is better than manual packing and can satisfy actual production requirements.

Bluecoke is a new type carbon product that prepared by low temperature carbonization process, which take lignite, long flame coal, not sticky and weak glue coal as raw material. At the same time tar and coke oven gas as by-products can be obtained. Two new technologies of Bluecoke production were introduced based on summary of way of producing Bluecoke by low metamorphic coal, namely the rich oxygen carbonization and the microwave carbonization. Both ways have their advantages and disadvantages. By contrast, the quality of coke and the content of valid gas are better using microwave carbonization, which to follow-up industry chains development significantly.

Genital infection by herpes simplex virus (HSV) produces a variety of clinical manifestations, patient presentations and management problems which differ in their severity and complexity. In the UK the currently available data for the incidence of genital HSV have been provided predominantly by the KC60 returns from diagnoses made in genitourinary (GU) medicine clinics. The increasing availability and recent publication of the first results, using HSV type-specific antibody tests within GU and non-GU patient populations, provide a tool to monitor trends in the epidemiology of HSV. It is, however, important to understand that the sexual behaviour which leads to this infection is variable and not necessarily general. The clinical availability of type-specific HSV antibody tests also gives rise to the possibility of screening individuals and informing those who test positive of their, previously undiagnosed, condition. The practicalities and problems of this approach need to be fully assessed. The possibility of uncovering previously undiagnosed cases through general practitioners is being considered, first, in terms of surveys of the general practitioners' management of genital HSV and, secondly, because the funding of health care in the UK has put the cost-effectiveness in GU medicine clinics under the spotlight. This paper will explore the new developments in the management of genital HSV and suggests adherence to the clear principles of diagnosis and treatment that is in the patient's best interest. This has the clear aim of improving the patient's quality of life, a factor which must remain paramount as new technologies, healthcare strategies and therapies become available.

The prospect of light-conducting concrete in railway construction is associated with an increase in recent years in interest in creating a barrier-free environment, including at railway stations, platforms, pedestrian crossings, in pedestrian tunnels, and so on. The material makes it possible to duplicate marking elements in hazardous areas of passenger movement at night without breaking the material environment, which will facilitate care for it in the winter. When creating innovative pedestrian crossings (equipped with interactive lanes that duplicate the traffic light for pedestrians), the use of light-conducting concrete will increase the antivandistance of the engineering arrangement. Unlike polymeric materials, the litracon material considered in the article does not change its properties under the influence of high temperatures, is not susceptible to instantaneous violation of the integrity and loss of surface properties under mechanical stresses. The high cost of the material does not yet allow its widespread use in the construction of railway infrastructure facilities on an industrial scale, however, with an increase in the production of optical fiber (the most expensive component of light-conducting concrete) and the search for new technologies that reduce the cost of its production, a drop in prices for this type of raw material is naturally expected. One of the areas of application of light-conducting concrete can be transport construction and landscaping of on-site territories (sidewalks, stairs, platforms) in terms of increasing their interactivity in the dark. The article proposes a composition (No. 1) corresponding to the compressive strength and tensile strength when bending, the requirements for products used in railway construction, for which light-conductive concrete can be used. The problem of light-transmitting concrete in the maintenance of railway infrastructure in the Republic of Belarus is being raised for the first time

Power And Energy

Centrifugal and vibrational technological effects are among the main approaches to intensify the process of plant raw materials hydrolysis for pectin extraction. With the impulse intensification of such a process, it is possible not only to increase its efficiency, but also to achieve the compactness of the equipment, reduce the cost of electricity and improve the quality of the product of hydrolysis. The hypothesis is confirmed, according to which the vibro-centrifugal intensification of hydrolysis increases the driving force of the process by not only activating the material flows of raw materials and reagents, but also by reducing the resistance in the technological environment. Graphical and analytical dependencies of the power and energy parameters of the oscillatory system were obtained, which proved the overcoming of the flow resistance of the liquid medium in the entire speed range of the drive shaft with the potential to intensify the process at a power consumption of 2.0 – 3.0 kW and or by the force of 2.3 – 2.5 kN using the Lagrange and Cauchy methods for composing and solving the equations of motion of the moving components of the tested hydrolyser with vibrating activators, and the methods of mathematical analysis and their processing in the MathCAD. The analysis of the presented parameters of the studied process of mixing the pectin-containing mass in the hydrolyser allowed us to determine the rational mode parameters of processing, which correspond to the angular velocity of the drive shaft  rad/s at the power consumption of 500 – 600 watts.

The Cost

The degree of purity of materials recovered from municipal solid waste (MSW) depends mainly on the objective: the intended use of the recovered material and the cost to recover this material in its pure form, determined by the intensity of the effort and the technology involved. The Bio-waste to Bio-plastic (B2B) Project aims to develop an integrated separation process at the bio-waste source, focusing on Hospitality Units. The quality of the collected bio-waste will be upgraded by removing foreign bodies or even specific categories of food waste, or by adding bio-waste from other, more specialized, sources (e.g. bakery residues) to produce compostable bio-plastics through an optimal synthesis process. Compostable bio-plastics are high added value products, which justify an increase in the cost of the preceding processes. After examining the possibility of further source separation and its results, B2B will study the optimal collection and transport system which decisively affects many qualitative elements, testing and evaluating a relatively high-cost but highly effective solution, that of hand-sorting in order to optimize materials recovery. B2B will identify all the parameters of the production process of PLA monomers and (poly) lactic acid in relation to the quality characteristics of the raw material (bio-waste) collected from Hospitality Units. Quantitative and qualitative analysis of food waste (bio-waste) produced in Hospitality Units will then take place. All the above will be tested on a bench-scale unit that will allow their further study and their substantial improvement, as well as the extraction of realistic results. Finally, the effect of the end-product bio-plastic on the composting and anaerobic digestion of bio-waste will be examined. The expected results from the B2B implementation are an optimized source separation scheme for Hospitality Units, the identification of the appropriate method of upgrading the quality of residues collected for the purpose of bio-plastic production, and eventually an integrated process of converting bio-waste into a high added value product.

DAST (4-dimethylamino-N-methyl-4-stilbazolium tosylate) crystal material was synthesized and purified by a relatively simple method. The synthesis process was easy to operate experimentally and the cost of raw materials can be cut down. The purification process was much easier than the previously published method. Fourier transform infrared spectrum (FTIR) was used to analyze the functional group of raw material and no extra functional groups were found. Nuclear magnetic resonance (NMR) study was performed to identify the different modes presented in the compound. The results showed that the quality of the prepared crystal raw material could meet the requirements on crystal growth. DAST crystals were grown from the synthesized raw material by slowly cooling method. The crystal structure was characterized by X-ray diffraction (XRD) study and the results showed that the crystal grown from the synthesized raw material was the same as that grown from pure DAST crystal raw material.

Abstract Osteoporosis has recently "walked in“ like an epidemic. It is a disorder that, due to industrialization and the application of new technologies, is today present in younger people lives. Modern devices used in everyday life have replaced the physical activity of man, and along with the sedentary lifestyle, had an impact on an increasing number of people affected by this disease. The effects of osteoporosis are significant because they represent a medical and social problem, and the cost of treating fractures requires significant economic expenditures [1,2]. Falls and injuries caused by them (e.g. fractures) are a growing problem for people in the third age group. Injuries and fractures cause pain plus functional disability, which consequently diminish the quality of life. The consequences increase costs of health care and cause mortality [3].

Organic cheeses are value added products that provide small dairy farmers with a viable source of income and has the potential to revitalize farms, provide new jobs, and develop new cheese varieties with unique flavours for consumers to experience. Production of hard organic cheese must comply with organic standards and regulations of organic production. Whole organic milk that does not contain residues of pesticides, hormones and antibiotics represents a quality raw material for hard organic cheese with added value. Together with the existing, producers develop and create new technologies and new branded products which are more original and recognizable. The goal of any technology is obtaining technologically reproducible protocol and constant uniform quality of the cheese with desired properties. In this paper some variables which influence quality of organic hard cheese were investigated. Tested samples of hard organic cheese from different production time showed consistent quality and obtained parameters followed the standards of full-fat hard cheeses.
