The agrochemical composition of chernozems typical of the agrobiological laboratory of Ternopil Volodymyr Hnatiuk National Pedagogical University has been studied and the economic expediency of using complex mineral fertilizer Plantafol 10.54.10 during cultivation of soybeans, to eliminate the shortage of some elements of mineral nutrition and increase crop productivity was analyzed. It was found that chernozems is characterized by a close to neutral exchange (pH 5.6) and hydrolytic (2.16 mg-eq. / 100 g) reaction, an increased amount of absorbed bases (19.0 mg-eq. / 100 g) and increased rate of saturation of bases (89.8 %), which is typical of agricultural lands with high carbonate content. Сhernozem soil has a low amount of easily hydrolyzed Nitrogen (102.0 mg / kg), an average supply of humus (2.63 %) and mobile Phosphorus (71.0 mg / kg) and a very high level of metabolic Potassium (189.0 mg / kg). Based on the specified agrochemical composition of the soil, taking into account the peculiarities of mineral nutrition of soybean plants, the importance for the formation of generative organs of Phosphorus and its ability to highly effective symbiotic nitrogen fixation in the study area, it is suggested to eliminate possible shortages of soil nutrients, in the first of Phosphorus, foliar fertilization with Plantafol 10.54.10. Complex mineral fertilizer Plantafol 10.54.10 contains Nitrogen – 10 %, Phosphorus – 54 %, Potassium – 10 %, as well as trace elements in chelated form EDTA – Boron 0.02 %, Iron – 0, 07 %, Manganese – 0.03 %, Zinc – 0.01 %, Copper – 0.005 %. It was found that double foliar fertilization with Plantafol 10.54.10 fertilizer at a dose of 3 kg / ha increases the yield of soybean grain cultivar Annushka, which is grown on chernozems typical of agrobiolaboratory, by 0.34 t / ha or 15.5 %. Yield growth was mainly due to a 16.8 % higher biological yield of aboveground mass and an increase in the number of beans on plants – by 15.3 %, seed weight – 16.0 %, total number of seeds – 11.4 %, as well as less pronounced increase in the height of attachment of the lower beans, the density and height of plants in the crop and the weight of 1000 seeds. The length of the fruits and their glazing did not change as affected by fertilizer. The obtained data allow to offer foliar fertilization with complex fertilizer Plantafol 10.54.10, as one of the elements of the system of soybean fertilization on chernozems with close to neutral reaction, increased amount of absorbed bases, low amount of easily hydrolyzed Nitrogen, average supply of humus and mobile Potassium and a very high level of exchangeable Potassium, which reduces the negative impact of deficiencies in the root nutrition of plants, increases crop productivity and provides additional income of 4078 UAH / ha.

The results of the research have revealed integrated effect of the mineral fertilizer application and protective measures influence on weed infestation and potato yield. This effect was developed on the second half of the vegetation and expressed in more stronger inhibition of plant development (from 36,6 to 20,4 and 11,1 g/m2 on low, medium and high levels of mineral nutrition, respectively), in the reduction of species diversity (from 12 to 10 and 10 species/m2) and number of weeds (from 69 to 42 and 32 species/m2). The highest biological (biomass reduction – 95,3%, the number of weeds – 79%) and economic (yield increase – 228 с/ha or 107%) effect was achieved by the high rates of mineral fertilizer application and combined protective measures of potato crops from weeds. This variant was characterized by the greatest profitability (125,3%), whereas chemical protection providing double treatment of potato plantings with herbicides, even at the middle and high level of mineral nutrition, was less effective (102,6 and 109%) in economic terms.

Climate change and global warming have a negative impact on coastal, especially small islands. Abration and floods can be very danger and need response to minimize the disaster risks. A simple and practical method is needed to inform the location and type of coastal vulnerability and its risks along coastal segments. Smartline is a coastal management method that represents the geomorphology of coastal, hinterland and shoreline. The North Pagai is a small island, a part of the Mentawai Islands that located at the west offshore of Sumatra Island and one of the under developed areas in Indonesia. The island is surrounded by the Hindia Ocean and located on a subduction path of tectonic plate that prone to earthquakes and Tsunami. High rainfall, strong winds, the complexity of coastal morphology and also the majority of coastal residents and limited infrastructure make the problems more complicated. Tsunami in 2010 (7.7 Mw) caused the change of shoreline getting worst on The East Coast of The North Pagai Island. This study aims to identify the coastal vulnerability using Smartline method. The research was conducted on April and September 2016. The result concludes that physical aspect shows Saumangaya and Matobe Village at high and also very high level of vulnerability hence Sikakap Village at very high level. The socio-economic aspect shows that The Sikakap Village is more advanced but contrary more vulnerable to disaster in terms of population density and complex activities. The North Pagai Island is a vulnerable island from physical and socio-economic aspects.

At present the laundry business is one of the promising businesses with targeted consumers from the upper middle class who do not have much time to wash clothes at home. Like other industries, laundry also produces wastewater that can have a negative impact on the environment if it is not managed properly. This study characterizes laundry wastewater and looks at its effect on the quality to the groundwater/wells close to the laundry business. Water samples include TSS, TDS, Turbidity, pH , COD, BOD, Phosphate, and Detergent parameters analyzed according to SNI and/or the HACH method (DR3900). Characterization of the laundry wastewater samples show a high level of detergent and phosphate parameters ranging from 27,7-39,4 mg/L and 6,1-27,1 mg/L, respectively with the highest levels corresponds to Laundry wastewater samples at Jalan Baru. The detergent and phosphate contents in all well water samples are still below the required quality standard. Although the concentrations of parameters analysed in the laundry wastewater  are very high and above the guidance, it is obvious from the well water samples results that there is no effect of laundry waste waters to the quality of ground waters.

The Impact

The research results of the foliar fertilization influence with different levels of mineral nutrition on the maize grain yield were presented, and the economic efficiency of growing of grain products was clarified. It was found that when increasing the mineral fertilizer dose from N30P30K30 to N45P45K45 and N60P60K60, the height of plants increased by 3 and 7 cm, the leaf surface area of one plant – by 4.8 and 10.9 %, respectively. Due to foliar fertilization, the height of plants increased by 2–5 cm, and the leaf area changed insignificantly. Depending on the background of mineral nutrition, it was accounted 98–99 ears per 100 maize plants, and in the case of foliar fertilization – 98–100 ears. The maize grain yield on the background of N30P30K30 was 7.56 t/ha, on the background of N45P45K45 and N60P60K60 – 8.65 and 8.68 t/ha, respectively. In the control variant (without spraying) the yield was 7.77 t/ha, and when plants fertilizing with urea (15 kg/ha) – 8.09 t/ha. The grain yield in the variants with maize plant fertilizing with a mixture of urea and micronutrients reached to 8.30–8.78 t/ha. The prime cost of 1 ton of maize grain when growing on the background of N30P30K30 was 1808 UAH, with increasing the fertilizer dose to N45P45K45 and N60P60K60 – 1781 and 1903 UAH, respectively. In the control variant, it was equal to 1828 UAH, in the variants under maize fertilization with urea (15 kg/ha) or a mixture of urea and micronutrients – 1827–1836 UAH. The conditional profit on the background of N30P30K30 was 21878 UAH/ha, it enlarged to 24264–25265 UAH/ha in the case of fertilizer dose increasing. In the control variant (without spraying) the conditional profit was equal to 22310 UAH/ha, when plants were fertilized with urea (15 kg/ha) – 23257 UAH/ha, with a mixture of urea and micronutrients – 23823–25155 UAH/ha. The highest level of profitability (163.9 %) was on the background of N45P45K45; the impact of foliar fertilization on this indicator was insignificant.

Studies at the South Ural Research Institute of Horticulture and Potato in 2015-2019 have been completed. Information on the nutritional value of soil mixture of various compositions has been obtained. The features of the mineral nitrogen nutrition of seedlings depending on the composition of the soil mixture have been identified. It has been established that the maximum profitability of production is achieved by using fertilizers of controlled release in the composition of the soil mixture on the basis of soil and peat. An increase in the content of macronutrients in the soil mixture has a significant effect on the survival rate of seedlings of fruit crops. Basacote fertilizer has a significant impact on the survival rate, growth and development of apricot, cherry, pear and plum seedlings when grown in small containers. The introduction of the Basacote norm of 2.5 g/l of the substrate into the soil mixture did not lead to a reduction in the survival rate of seedlings of the studied crops compared to the control. Higher Basacote fertilizer rates led to a significant reduction in survival rate. The minimum survival rate of seedlings was noted in the variant with the Basacote fertilizer norm of 7.5 g/l of the substrate and varied from 23.3 % for apricot and plum to 55 % for pear (a very high level of soil nutrition). The maximum yield of marketable seedlings was obtained in the variant with a high level of mineral nutrition: 57.7 % for pears, 50 % for plums, 30 % for cherries and 45.4 % for apricots. The maximum estimated profitability was obtained on the pear and amounted to 120 %.

An anaerobic inverse turbulent bed, in which the biogas only ensures fluidisation of floating carrier particles, was investigated for carbon removal kinetics and for biofilm growth and detachment. The range of operation of the reactor was kept within 5 and 30 kgCOD· m−3· d−1, with Hydraulic Retention Times between 0.28 and 1 day. The carbon removal efficiency remained between 70 and 85%. Biofilm size were rather low (between 5 and 30 μm) while biofilm density reached very high values (over 80 kgVS· m−3). The biofilm size and density varied with increasing carbon removal rates with opposite trends; as biofilm size increases, its density decreases. On the one hand, biomass activity within the reactor was kept at a high level, (between 0.23 and 0.75 kgTOC· kgVS· d−1, i.e. between 0.6 and 1.85 kgCOD·kgVS · d−1).This result indicates that high turbulence and shear may favour growth of thin, dense and active biofilms. It is thus an interesting tool for biomass control. On the other hand, volatile solid detachment increases quasi linearly with carbon removal rate and the total amount of solid in the reactor levels off at high OLR. This means that detachment could be a limit of the process at higher organic loading rates.

In theory, and under some very strong assumptions, there exists a tight quantitative relationship among the following four fundamental economic concepts: (1) ‘wealth’; (2) ‘income’; (3) ‘sustainability’; (4) ‘accounting’. These four basic concepts are placed in quotation marks here because a necessary first step will be to carefully and rigorously define what exactly is meant by each. This chapter reviews what is known about this important fourfold quantitative relationship in an ultra-simplified setting. It identifies some basic applications of this simplified economic theory of wealth and income (and sustainability and accounting). While the contents of this chapter are expressed at a very high level of abstraction and require many restrictive assumptions, the fundamental fourfold relationship it sharply highlights should be useful for conceptualizing, at least in principle, what is ‘wealth’ and what is its theoretical relationship to ‘income’, ‘sustainability’, and ‘accounting’.

AbstractSchizophrenia is a chronic mental condition presenting a wide range of symptoms. Although it has a low prevalence compared to other mental conditions, it has a negative impact on social and occupational functions. This study aimed to assess the appropriateness of antipsychotic medications administered to schizophrenic patients and describe current treatment patterns for schizophrenia. A retrospective cohort study was conducted in all patients over the age of 15 with an active diagnosis of schizophrenia and treated with antipsychotics between 2008 and 2013 in the Valencia region. A total of 19,718 patients were eligible for inclusion. The main outcome assessed was inappropriateness of the pharmacotherapeutic management, including polypharmacy use. Altogether, 30.4% of patients received antipsychotic polypharmacy, and 6.8% were prescribed three or more antipsychotics. Overdosage affected 318 individuals (1.6%), and 21.5% used concomitant psychotropics without an associated psychiatric diagnosis. Women and people with a comorbid condition like anxiety or depression were less likely to receive antipsychotic polypharmacy. In contrast, increased polypharmacy was associated with concomitant treatment with other psychoactive drugs, and only in user on maintenance therapy, with more visits to the mental health hospital. Overall, we observed a high level of inappropriateness in antipsychotic prescriptions. Greater adherence to guidelines could maximize the benefits of antipsychotic medications while minimizing risk of adverse effects.
