The amount of dust is an important indicator in evaluating the quality of down and feather. However, there has been little published research on dust in down and feather and no report of the generation of dust and its reduction. We extracted dust from down and feather and divided it into water-soluble dust and floating dust based on solubility and then calculated the proportion of the two types of dust. The morphology of floating dust was characterized and a formation mechanism proposed for fine dust. A machine was designed to reduce the dust from down and feather during washing. Floating dust was a major component of down and feather dust, accounting for up to 71.5% (m/m). The main component of floating dust was organic material. The fibrillation and pulverization of down fibers is proposed as the main cause of fine organic dust. An overflow de-dusting and centrifuging integrated device was constructed to replace the traditional centrifugal dehydration machine in the washing of down and feather. The dust level was reduced significantly when using the new machine, especially floating dust. Therefore the dust problem will be better resolved by using this technology in the down-washing process, alleviating the health concerns of workers and helping the industry to become more sustainable.

Studies have been carried out to improve the quality of conversion calcium carbonate. The process of extraction of insoluble iron-containing impurities at the stage of obtaining calcium carbonate from calcium nitrate melt was studied. It has been determined that the preliminary removal of the acid-insoluble residue from the melt of Ca (NO3)2by filtration or settling allows the Fe2O3content to be reduced by more than 50 % in the form of magnetically susceptible impurities and further increases the whiteness of the final product. The effect of grinding and heat treatment of conversion calcium carbonate on the evolution of nitrogen-containing impurities is studied. It has been established that the amount of water-soluble substances in the sample increases exponentially with increasing shredding time of the material. Heat treatment can significantly reduce (in almost 3 times) the total content of water-soluble substances in the crushed product. Simultaneously with the removal of the "bound" nitrogen, the content of the main component increases by 1.5–2 %. A positive effect of heat treatment is also an increase in the rate of refinement of conversion calcium carbonate, which makes the dispersed composition of the product more homogeneous. A technological scheme for processing conversion calcium carbonate into a disperse filler with specified properties has been developed.

In recent years, breast cancer (BC) is the most common cancer pathology and the most common cause of disability among women in developed countries. Finding the most effective ways of interaction between the patient and the doctor creates the preconditions for the necessary analysis of the treatment process from an objective and subjective point of view. Therefore, an important indicator to be taken into account is the quality of life of a patient. To compare the indicators of a comprehensive assessment of the quality of life of patients to the adverse locally advanced forms (LA) of breast cancer before and after systemic intravenous polychemotherapy (SPCTx) and selective endolymphatic polychemotherapy (ELPCTx) in neoadjuvant mode. The study was conducted on the basis of a random analysis of outpatient cards from 112 patients with LA BC T4A-DN0-3M0 who received a comprehensive antitumor treatment on the basis of the Donetsk regional antitumor center and the University Clinic of the Odessa National Medical University from 2000 to 2017, which was proposed a questionnaire at various stages of preoperative treatment. The first (control) group consisted of 65 patients (58 %) with inoperable forms of LA BC, which was performed in neoadjuvant mode by SPCTx. The second (study group) included 47 patients (42 %) with inoperable forms of LA BC, which was performed as a neoadjuvant course ELPCTx. According to the integral indicators of quality of life and quality of health between patients in the control and study groups, there was no statistically significant difference. In a detailed analysis of the indicators of symptomatic scales, the difference between the groups did not exceed the critical. Based on the results of a study conducted among patients receiving endolymphatic chemotherapy in a neoadjuvant mode, the subjective evaluations of treatment in absolute numbers have better reference values without statistical superiority. The study of the integrative indicator of quality of life and its discrete elements is an ergonomic and economical means of heuristic assessment of the health of patients in order to further develop more rational and convenient ways of solving urgent issues of modern oncology by increasing compliance and finding a compromise between the physician and the patient.

Nutrients released from sediments have a significant influence on the water quality in eutrophic lakes and reservoirs. To clarify the internal nutrient load and provide reference for eutrophication control in Yuqiao Reservoir, a drinking water source reservoir in China, pore water profiles and sediment core incubation experiments were conducted. The nutrients in the water (soluble reactive P (SRP), nitrate-N (NO3−-N), nitrite-N (NO2−-N), and ammonium-N (NH4+-N)) and in the sediments (total N (TN), total P (TP) and total organic carbon (TOC)) were quantified. The results show that NH4+-N was the main component of inorganic N in the pore water. NH4+-N and SRP were higher in the pore water than in the overlying water, and the concentration gradient indicated a diffusion potential from the sediment to the overlying water. The NH4+-N, NO3−-N, and SRP fluxes showed significant differences amongst the seasons. The NH4+-N and SRP fluxes were significantly higher in the summer than in other seasons, while NO3−-N was higher in the autumn. The sediment generally acted as a source of NH4+-N and SRP and as a sink for NO3−-N and NO2−-N. The sediments release 1133.15 and 92.46 tons of N and P, respectively, to the overlying water each year.

The enhancement of human well-being is one of the ultimate goals of resource management; however, it is not explicitly considered by forest policy indicators. Our previous studies examined how Japanese citizens in the Yasu River watershed of the Shiga Prefecture perceived subjective well-being related to forests (forest SWB). We found a negative correlation between forest SWB and forest ownership, suggesting dissatisfaction with the low profitability of forest ownership. Based on this result, in this paper, we argue that forest SWB can be an important indicator for policymaking in the context of urbanization and forest restoration and can complement existing forest indicators focusing mainly on physical and objective properties. First, we propose that a direct measurement of well-being (e.g., forest SWB) is preferable over an indirect measurement (e.g., GDP), for policymaking processes related to forests. Second, forest SWB can reflect the quality of our interactions with forests, which is important in urbanized societies which tend to have reduced experiences with nature. Third, forest SWB could identify inequalities between the users of forest ecosystem services and forest managers. Overall, forest SWB can be a holistic indicator to capture a variety of perspectives held by citizens.

Background: Attachment to parents during adolescence has been identified as an important indicator of psychosocial adaptation. However, the relative importance of the adolescents’ behavior problems and the larger relational context likely to influence the quality of these relationships remains relatively underexplored. The present study aims to identify the factors associated with the quality of parent–adolescent attachment relationships and to establish their relative contributions. This study also tested, as a complementary objective, the invariance of the models according to sex. Method: 706 (46.9% girls) early adolescents participated in the study at time 1 and then again, two years later. The individual (e.g., behavior problems or temperament) and contextual (e.g., parents’ behaviors, history of abuse or environment stability) associated factors were measured at time 1, while the quality of the parent–adolescent attachment relationship was measured at time 2. Results: The results showed that a history of emotional abuse, inconsistent discipline, externalized behavior problems and the adolescent’s age were negatively associated with the global attachment security score, while internalized behavior problems and peer attachment were positively associated. These variables explained 15.7% of variance. The results also demonstrated that these variables were also associated with the specific dimensions of attachment (trust, communication, alienation). Discussion: The study demonstrates the importance of several relational variables in the development of the parent–adolescent attachment relationship.

Abstract Background Nutrient Profiling Systems (NPSs), including the UK Food Standards Agency NPS and its variants are used to classify foods according to their nutritional composition for nutrition policies. The prospective validity of these NPSs requires however further investigation. The study investigates the associations of the original Food Standards Agency (FSA)-NPS and three variants - the Food Standards Australia New Zealand Nutrient Profiling Scoring Criterion (NPSC), the Health Star Rating (HSR) system NPS and the French NPS (HCSP-NPS) -, which are used as a basis for nutrition policies, with weight status. Methods Dietary indices based on each of the four investigated NPSs applied at the food level were computed at the individual level to characterize the diet quality of 71,178 French individuals from the NutriNet-Santé cohort. Associations of these Dietary Indices (DIs) (as tertiles) with weight gain were assessed using multivariable mixed models, and with overweight and obesity risks using multivariable Cox models. Results For the four NPSs, participants with a lower diet nutritional quality were more likely to have an increase in body mass index over time (median follow-up of 3.14 ± 2.76 years, beta coefficients positive, all p ≤ 0.0001), and an increased risk of overweight (HRT3vs.T1=1.27 [1.17-1.37] for the HCSP-DI, followed by the original FSA-DI with HRT3vs.T1=1.18 [1.09-1.28], the NPSC-DI with HRT3vs.T1=1.14 [1.06-1.24] and the HSR-DI, HRT3vs.T1=1.12 [1.04-1.21]). Whilst differences were small, the HCSP-DI appeared to show significantly greater association with risk of overweight compared to other NPS. Conclusions Less healthy diets defined using the Food Standards Agency-NPS and related systems were all associated with weight gain and overweight risk. Demonstrating this association with health outcomes is an important indicator of one validity dimension of NPSs and supports their use in public policies for the prevention of diet-related chronic diseases. Key messages Nutrient profile models of foods and beverages allow capturing the nutritional quality of diets and are prospectively associated with weight gain and obesity. The French NPS which underpins the front-of-pack Nutri-Score appeared to have a small but significant higher performance.

Cr3C2-NiCr has high quality of wear resistant properties and is widely used in abrasive environment. In this paper, Cr3C2-NiCr coating was prepared on 45 steel by laser cladding technology. Analysis and research of the coatings were achieved by SEM and XRD to determine the main component and the different region on coatings. The hardness and the element component were investigated by micro-hardness tester and EDS. Abrasion tests were performed to contrast the wear resistance of two materials. The results indicate that the hardness of the coatings is nearly 3 times as the substrate. The coatings are well combined with the substrate and the phase of Cr3C2 has a large proportion in the coatings. Abrasion tests show that the average of wear rate on substrate is 5.2 times as the coatings.
