During the distillation of the fermented fruit mash or juice, ethanol and water are the carriers of a huge number of the other volatile aroma compounds. Unique and distinctive flavour of the final spirits depends on their quantity and quality. Fruit spirits have higher concentration of almost all types of volatile compounds with comparing to other types of distilled spirits. The art of distillation run is to obtain the best balance between congeners present. Two different types of distillation equipment are used for the production of fruit spirits: copper Charentais alembic and batch distillation columns. Although both distillation methods are based on the same theoretical principles, a different quantity of the flavour compounds of the final spirits is produced by using different distillation equipment. The main difference was shown in different distributions of the methanol, n-propanol, higher alcohols and fatty acid esters. Distillation methods need to be adjusted for each fruit spirits regardless to distillation equipment employed because fermented mash of different fruit varieties has a different requirement for distilling. Alembic stills yield better aroma and more characteristic fruit distillates but are slow and require more labour. Column still cleans the distillate giving a decent aroma and higher concentration of alcohol.

The waste is a product of everyday human activities, and we are faced with large amounts of waste daily. Inadequate method of waste treatment effects are numerous: pollution of the environment and hazards to human health, the loss of useful components from waste, or the exploitation and consumption of natural resources. In the XXI century the sustainable management of municipal waste will become essential in all stages, from planning to construction, handling, recycling and final decomposition. Range of new and existing technologies for waste treatment and waste management strategies require the maintenance of environmental quality at the moment, but also the fulfillment of sustainability in the future. Integrated waste management should meet certain priorities in line with the waste hierarchy, such as requirements for recycling waste, to increase the use of renewable energy in order to looking for more socially acceptable options, and to preserve biodiversity and natural ecosystems simultaneously. Achieving these goals is possible only if all technical and non-technical aspects of solid waste management system are analyzed as a whole, because they are interrelated, and development in one area often influences the practice or activity in another area. Various analytical tools and methods are used to help in decision making in waste management systems. Analytical methods used in the waste management system can be classified into two groups: engineering models and models of assessment system.

Abstract Introduction. Bone disease is a chronic complication of chronic kidney disease and major clinical problem in hemodialysis (HD) patients. The aim of our study was to assess the influence of treatment longevity on biochemical parameters of mineral and bone metabolism in HD patients, and to identify the most important parameters. Methods. The research was observational and retrospective, involved 70 patients, mean age 58.69±12.54, divided into groups in respect to the duration of dialysis treatment (Group I-5 years, Group II-5-10 years and Group III-over 10 years). Results. Serum phosphorus was increased, but the values tend to increase along with dialysis duration - (Group I: 1.93±0.45; Group II: 1.97±0.50; Group III: 2.01±0.37; p>0,05). Calcium values were also not significantly increased based on the duration of treatment [Group I: 2.3 (2.2-2.41); Group II: 2.46 (2.15-2.6), Group III: 2.35 (2.10-2.52)]. Dialysis and PTH correlated positively in the first group of patients (Rho=0.470, p=0.013). The values of calcium and alkaline phosphatase correlated positively in all patients (Rho=0.351, p=0.003). PTH was significantly higher in the second and third compared to the first group (p=0.009 and p=0.038, respectively), and there was no significant difference between the second and the third group. Interestingly, parathyroidectomized patients had higher PTH values compared to those without parathyroidectomy (557 vs. 359 pg/ml). Conclusion. The most reliable marker for clinical monitoring of bone disease in dialysis patients is PTH. The values of calcium and phosphorus are highly variable and not reliable parameters for bone disease follow-up.

IntroductionThe addiction to heroin is a severe disorder and its treatment represents a complicated, long-lasting process, which includes a series of various interventions which have to be constantly adjusted to patients' present state and his abilities to accept the therapy. The addiction is very resistant to treatment and if the program is not at the same time, enough influential and persistent, but also acceptable to the addict to stick to it for months or even years, the expected results will not be achieved. Retention to the program, abstinence from the illicit drugs, reduction of illegal activities and improving the aspects of socially acceptable behaviour are the best indicators of therapeutic efforts [1-5].Already thirty years ago, the most of western-European countries and USA, Canada and Australia have accepted the use of methadone as a recognized method for treatment of opiate addicts and a useful tool in the frame of 'harm-reduction' approach for helping the not-motivated or incurable heroin addicts. Methadone enables those patients to stop or significantly reduce taking heroin. Although methadone does not create the feeling of euphoria similar to the effect of heroin, it replaces the biological lack of endorphins at the opioid receptors in brain and, with its help, the patient can achieve a psychophysical balance and control the pathological addict's craving. The use of methadone is the best way to attract the addicts from the street to the process of treatment and, if it is well organized and spread, can ultimately direct many addicts towards the programs that would help them in stabilizing the permanent abstinence [1-5].In the evaluation study carried out by the American National Institute for Drugs (NIDA) it has been found that the substitution therapy reduces users' heroin intake for 70%, and their criminal activity by 57 %. [6]. It has also been reported that the countries which use methadone attract up to 75% of opiate addicts to their programs, while those that do not use it, achieve less than 20 %, making the mortality of addicts due to overdose very high. A large number of addicts included in substitution programs function better socially, i.e. better fulfill their duties at the workplace and in families and display significantly less dealings with criminal activities, particularly with selling drugs, thus reducing the risk of initial drug abuse among the healthy population. Application of methadone improves the physical and mental health of the addict, his life gets longer and the risk for early sudden death is reduced. By using methadone, physical and mental health of addicts is improved, their lifespan prolonged i.e. the risk of sudden death is reduced. The addicts in substitution programs are less dangerous concerning the spread of HIV infection, hepatitis and encouraging others to take drugs. The use of methadone in pregnancy is absolutely indicated: it reduces the risk of unwanted pregnancy termination and the risk of damaging the fetus. [1]."Drug free" residential treatment of addictions in the frame of therapeutic communities (TZ) started in early sixties as groups of self and mutual help, as an alternative to the existing conventional programs. The mean duration of stay differs from TZ to TZ (18-60 months). The staff consists mostly of former addicts, while the rest of the staff consists of medical professionals from the field of mental health, psychologists, defectologists, and pedagogues and similar. The aim of staying in TZ is a global change of lifestyle, including abstinence from the illegal substances, elimination of anti-social activities, gathering skills for job-finding and the development of pro-social efforts and values. In TZ, detoxification is the condition to enter the treatment and not the goal of it. Most of the patients who enter TZ already have histories of multiple drug abuse, significantly disturbed psychosocial functioning and consequently, significantly lower quality of life. …

In this paper, we present a study of intrinsic bipolar resistance switching in metal-oxide-metal silicon oxide ReRAM devices. Devices exhibit low electroforming voltages (typically − 2.6 V), low switching voltages (± 1 V for setting and resetting), excellent endurance of > 107 switching cycles, good state retention (at room temperature and after 1 h at 260 °C), and narrow distributions of switching voltages and resistance states. We analyse the microstructure of amorphous silicon oxide films and postulate that columnar growth, which results from sputter-deposition of the oxide on rough surfaces, enhances resistance switching behavior.
