Hintergrund: Pflegende werden zunehmend von der Industrie umworben. Ziel: Erfassung der Einstellungen und des Verhaltens von pflegerischen Wundexpert(inn)en gegenüber der Industrie. Methode: Auf Basis bestehender Instrumente wurde ein standardisierter Fragebogen (39 Items; 5-stufige Likert-Skala) entwickelt, der elektronisch und postalisch an alle pflegerischen Mitglieder der Österreichischen Gesellschaft für vaskuläre Pflege (ÖGvP), der Deutschen Gesellschaft für Wundheilung und Wundbehandlung e. V. (DGfW e. V.) und der Swiss Association for Wound Care (SAfW) versandt wurde. Ergebnisse: Die Stichprobe umfasste 178 Pflegende (75 % Frauen; Alter 27 – 70 Jahre [Median 45]; 0 – 40 Jahre [Median 9] tätig im Wundbereich). Nur etwa jeder vierte der Befragten (23,0 %) hat im vergangenen Jahr nicht am Pharmamarketing teilgenommen. Allgemein wurden kleine Geschenke häufiger angenommen als teure Geschenke. Mehrheitlich werden preiswerte Geschenke, Geschenke zu Ausbildungszwecken und solche, die den Patienten nutzen können, als positiv bewertet. Die Befragten betrachten sich, im Vergleich zu Ärzt(inn)en, mehrheitlich als eher weniger beeinflussbar in ihrem Entscheidungsvermögen. Schlussfolgerungen: Das Verhalten und die Einstellung der Pflegenden sind ambivalent. Das Auftreten von Interessenkonflikten wird teilweise mit dem Wohl der Patient(inn)en begründet. Mangelhafte Kenntnisse über diese Thematik und soziale Erwünschtheit könnten die Ursache für eine unkritische Haltung sein. Für einen kritischeren Umgang mit der Industrie sind Bildungsmaßnahmen und berufsethische Standards notwendig.

Walnut trees are grown worldwide for their edible fruits, which have high nutritional value. To address climate change, researchers have studied walnut phenology to create cultivars adapted to warmer climates. The objective of this study is to propose a scale for phenological Persian walnut observations using the Biologische Bundesanstalt, Bundessortenamt, und CHemische Industrie (BBCH) codification and alignment with historical alphameric scales. Here, the principal growth stages (PGSs) of Persian walnut (Juglans regia L.) are described using stages from a previously available alphanumeric scale. This standardised phenological scale describes Persian walnut growth from the dormant vegetative state through reproductive budding and senescence. This phenological scale is expected to increase the efficiency of walnut phenological monitoring. Fifty-seven stages are used to describe the life cycle of Persian walnut in this BBCH scale. Of these 57 stages, 3 stages are dedicated to seed germination (PGS-0), 4 stages are dedicated to bud development (PGS-0), 7 stages are dedicated to leaf development (PGS-1), 4 stages are dedicated to stem elongation (PGS-3), 8 stages are dedicated to inflorescence emergence (PGS-5), 5 stages are dedicated to male flowering (PGS-6), 5 stages are dedicated to female flowering (PGS-6), 5 stages are dedicated to fruit development (PGS-7), 12 stages are dedicated to fruit ripening (PGS-8), and 4 stages are dedicated to leaf senescence (PGS-9).

Alpine plant species are perennial but have a shorter growing period according to prevailing habitat conditions that remain snow-covered during winter. In these areas, many of the species are important sources of valuable drugs. Phenological observations on Meconopsis aculeata were recorded at a weekly interval in Tungnath region of western Himalaya. Phenological studies in alpine plants are minimal, especially in Indian Himalayas thus, the present study was carried out to describe detailed phenological stages of M. aculeata in Tungnath region of the Indian Himalaya. The BBCH (Biologische Bundesantalt, Bundessortenamt, and Chemische Industrie) scale was used to characterize seven primary growth stages from seed germination to senescence, as well as secondary growth stages. These stages include stage 0 (germination phase), stage 1 (leaf development), stage 5 (Inflorescence emergence), stage 6 (flowering), stage 7 (fruit development), stage 8 (Fruit ripening) and stage 9 (Senescence). Due to the high market demand of medicinal plants in local and international markets, work on the various aspects of domestication and crop improvement is a dire need, therefore the detailed phenological growth stages of M. aculeata could be helpful and complimentary for local growers, breeders and researchers.

Portulaca oleracea L., known as purslane, is an unconventional food plant rich in nutrients and medicinal properties, with potential for consumption and commercialization. The objective was to describe phenological stages of purslane based on BBCH (Biologische Bundesantalt, Bundessortenamt and Chemische Industrie) scale and thermal sum at different times. Evaluations were made from two genotypes, the Golden variety and an access. Plants were observed during six consecutive periods, interspersed every two months. Thermal sum and base temperature were obtained considering the average temperature from seedling emergence to flowering and dispersion of the first capsule in 50% of the plants. The phenological cycle of Purslane based on the BBCH scale shows seven main stages, subdivided into secondary stages: germination (0); leaf development on the main branch (1); development of lateral branches (2); development of flower buds (5); flowering (6); seed dispersal (8); and senescence (9). The lower base temperatures (Tb) determined to flowering were 10 to 15 ºC for the variety Golden and access, respectively, since for seed dispersal, Tb was 9 and 13 ºC, respectively. Thermal requirements for Golden variety are 421.3 GD for flowering and 644.2 GD for seed dispersal, while for access they are 239.7 and 407.0 GD, respectively. Purslane as a food plant can be produced throughout the year in tropical region and may be best used if harvested until the plants reach 12 or 10 leaves.

In order to improve the adhesion between cement and zirconia, aluminum oxide sandblasting (JAT) and Rocatec, sandblasting with silica coated aluminum oxide (ROC), also the primer Signum Zirconia Bond (SZB) were used. The objective of the study was to verify the influence of the surface treatment and the presence of SZB primer in relation to the bond strength between cement and zirconia, using 60 zirconia specimens measuring 7 mm in length, 7 mm in width and 3 mm in length. thickness. Three surface treatments were evaluated: sandblasting with pre-sintering aluminum oxide (OPre), Rocatec Soft before (RPre) and zirconia final sintering (RPos), and also, regarding the presence or not of SZB. All specimens were cemented with Panavia F. The bond strength (RU) was evaluated through a shear test with a standardization device from SDI (Southern Dental Industrie) on a universal testing machine (Kratos), with a speed of 0 , 5 mm / min. The data were evaluated using Kruskal-Wallis / Mann-Whitney (α = 0.05). Average (SD) of UK without the use of SZB: OPre: 5.5 (0.9) Ba; RPre: 4.0 (1.4) Bb; RPos: 5.0 (0.5) Bab. Average (SD) of UK using SZB: OPre: 7.9 (1.5) Aab; RPre: 6.7 (2.3) Ab; RPos: 9.0 (1.2) Aa. The use of primer increased the cement / zirconia bond strength regardless of the surface treatment performed, in addition, the Rocatec group after sintering with primer, obtained higher bond strength values compared to the other study groups.

The soursop is a species of tropical fruit well accepted by consumers due to its creamy white pulp and excellent flavor. Currently, Mexico is the largest producer and consumer; however, the agronomic practices in use were established without a systematic knowledge of A. muricata L. phenology. The objective of this work then, was to conduct such a study in two of the main producing regions of Mexico: Tepic and Compostela (both in the state of Nayarit). For this, a total of 20 ungrafted trees were selected and their growth stages described using the extended BBCH-scale (Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie). Overall, eight main phenological stages were identified over the course of a year. These were: the development of buds (stage 0), leaves (stage 1),and shoots (stage 3), the emergence of flowers (stage 5), flowering (stage 6), fruit development and maturity (stages 7-8), and senescence of branches (stage 9). In addition, 37 secondary growth stages were also described and quantified. The highest number of vegetative shoots occurred from March-July, 2017 and the biggest increase in floral structures from July–September, 2017. Fruit setting to physiological maturity took an average of 114 days in both Tepic and Compostela, with the most intense defoliation occurring in October, 2017 in the former (Tepic) and in December, 2016 in the latter (Compostela). Hopefully, improved agronomic practices will be established using this information, as well as suitable protocols for future physiological studies.

ABSTRACT Arid region is characterised by extreme climatic condition, poor soil health and over-exploitation of natural resources. Under prevailing conditions of arid India, Ficus carica is an emerging fruit crop with high commercial value and nutritional significance. Phenological study plays an important role in ensuring efficient crop management practices, but such studies in fig have not yet been conducted in India. The present study was conducted with an aim to define and describe phenological stages of common fig cultivar ‘Diana’ in arid regions according to the Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH)-scale using two-digit numerical system. The BBCH scale markedly explains various developmental stages of crops. Seven principal growth stages, viz. bud development (0), leaf development (1), shoot development (3), inflorescence development (5), flower development (6), syconium (fig receptacle) development (7) and fruit maturation (8), and 25 secondary growth stages of fig have been described. The sequential progression of principal growth stages of fig indicated temporal variation in growth pattern as well as overlapping of secondary growth stages. Phenological description will act as a pragmatic approach to define growth stages in order to facilitate timely agronomic practices such as canopy management, nutrient management and irrigation scheduling, pest and disease management. Since fig is considered one of the important minor fruits of India, a detailed phenological description will be instrumental in enhancing its potential in arid and semi-arid regions.

This paper attempts to evaluate the transformation and upgrading (T&U) levels of the three industries in 11 prefectures of Zhejiang Province, China, since 2016. Taking the provincial T&U levels of the three industries as the benchmark, the three industries in each prefecture were analyzed by shift-share method (SSM). The main results are as follows: In terms of primary industry, none of the 11 prefectures had structural advantage (structural shifts < 0), but 3 had regional competitiveness (competitiveness shifts > 0); in terms of secondary industry, none of the 11 prefectures had structural advantage (structural shifts < 0), but 5 had regional competitiveness (competitiveness shifts > 0); in terms of tertiary industry, all of the 11 prefectures had structural advantage (structural shifts > 0), and 6 had regional competitiveness (competitiveness shifts > 0); Shaoxing was competitive in all three industries, ranking the first in the competitiveness of every industry; Huzhou, Quzhou, and Jinhua were not competitive in tertiary industry. The research provides a new yardstick of industrial T&U level and lays the decision-making basis for local governments in Zhejiang to formulate industrial T&U policies.

Cutleaf groundcherry (Physalis angulata L.) is a plant that belongs to the Solanaceae family. In Indonesia, this plant grows spread in various regions and has different names in each region. However, this plant is rarely cultivated and is generally considered a weed by farmers. Recently many studies have shown that cutleaf groundcherry contains many substances that are beneficial for the health sector, so it has the potential to be developed as a cultivation plant for exotic fruit sources that function as nutraceuticals. Plant breeding programs can be a solution in responding to these problems. As the first step in developing cutleaf groundcherry through a breeding program, the Plant Breeding Laboratory, Faculty of Agriculture, Brawijaya University, collected accessions of cutleaf groundcherry from various regions in Indonesia. The phonological stage of its growth is one piece of information that is useful in better understanding the cutleaf groundcherry life cycle and, as a result, simplifying cutleaf groundcherry cultivation management. This research aims to provide practical knowledge on the cutleaf groundcherry life cycle to develop a more efficient plant management approach for cultivation, including plant breeding initiatives. The BBCH scale was used to make observations (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie). The descriptive statistics obtained from observations and presented in descriptive narrative form using the BBCH scale with 3-digit coding numbers and documentation images were used in the data analysis. The results showed that the BBCH scale was used to define and describe cutleaf groundcherry phenology, which included germination (stage 0), leaf development (stage 1), side shoot formation (stage 2), the emergence of inflorescence (stage 5), flowering (stage 6), fruit development (stage 7), fruit and seed ripening (stage 8) and senescence (stage 9)

The main objective of the present study is to assess the level of contamination, source identification, and health risk assessment of heavy metals in the industrial soils of Aurangabad. A total of 15 Soil samples were collected with a sampling density of 3–5 composite soil samples from 0–10 cm surface soil, analyzed heavy metals (Ni, Pb, Cd, Zn, Cr, Mn, Fe, and Cu) using atomic absorption spectroscopy. The geographical information system (GIS) technology like Kriging and inverse distance weighted interpolation (IDW) was used for the preparation of spatial distribution maps. A significant spatial relationship was found for Ni, Cd, Zn, Pb, and Cu in the soils using a GIS-based analysis, suggesting that these metal contaminants in the industrial area had common sources. Assess the risks of contamination for heavy metals in the soil were assessed based on a geo-accumulation index (Igeo) and contamination factor (CF). According to the Igeo and CF, most of the samples vary between 0 to 1, unpolluted to moderately polluted except Cd values. Most of the measured heavy metals showed the highest availability in top soils collected from around the steel and metal industries of the Waluj MIDC area. Also, based on the outcomes of the health risk assessment, particular attention should be paid to Ni, Pb, Cd, Zn, Cr and Cu in the industrial soils of Aurangabad. This study is socially beneficial for prevailing human health hazards in such industrially populated regions.

One factor contributing to the environment's waste is industrial activity both large and small scale. During this time, the waste collection is done by dumping it into a ditch and flowing it into the river, thus worsening environmental sanitation. This study aims to analyze the character of edible films of corn starch with protein isolates from the extraction of tofu processing industry wastewater. Samples were analyzed to determine the tensile strength and elongation of the resulting film by varying the amount of protein isolates, 0%, 3%, 5%, 7% and 9%. The protein extraction process was carried out by centrifugation, while the water vapor transmission test was by the saucer method, while the identification of functional groups was through FTIR analysis. The results showed that the highest mechanical properties were obtained in the variation of 5% protein isolates with a value of 52.16 MPa and elongation of 38.4%. For water vapor transmission rate (WVTR), film comparisons were made with 5% variation of protein isolates and 0% protein isolates. Films with 5% protein isolates have a smaller water absorption of 0.56%, than films with 0% of 0.66%. The value of water vapor transmission rate shows a very significant ratio, at 5% protein isolate of water vapor transmission at 0.00176 g/m2/day, much smaller than 0% protein isolate at 0.00864 g/m2/day. IR spectra showed the presence of amide groups I and II on the results of the analysis of protein isolates. While the globular structure of proteins is shown by the absorption of wave numbers 1667 and 1650 cm-1.

The article presents a comparative analysis of maturity level in Industry 4.0, of Brazilian companies with German Industry, seeking to identify learning opportunities to increase competitiveness. It was used the maturity model in Industry 4.0 developed by VDMA (German Mechanical Engineering Industry Association), applied to German companies, serving as benchmark. The same model was applied to Brazilian companies, from the State of Espírito Santo, located in the most developed region of the country, but with lower industrial density, and which has great challenges to increase its participation in the national and international markets. A field research was carried out with 46 industries, which participated in workshops to understand the fundamentals and to evaluate the maturity level in Industry 4.0. The individual results were processed by the platform of VDMA, indicating the levels in six dimensions of the model and the general result on a scale of 0 to 5. The results of all companies were tabulated, allowing the comparison with the research carried out with German companies. The study showed that, on average, Brazilian companies have the same level of maturity of German companies in readiness for Industry 4.0, with grade 0.9 in a scale of 0 to 5. But, there are significant differences in compared dimensions. 5.6% of German companies are at the advanced level in Industry 4.0, especially the technology developers, while Brazilian companies studied are still at the most basic levels. Both Industries are skeptical about investments in Industry 4.0 and the level of evaluation on Strategy dimension is still low. The comparison of expectations and difficulties allowed identify essential points to support these companies to follow the way to Industry 4.0.

Industrial activities have various effects on biodiversity, posing significant threats to forest ecosystems. The current study describes the species composition, taxonomic diversity, and stand structure at Bhawal Sal forest, Gazipur, Bangladesh, as they are affected by industrialization. To achieve the goal, 30 different categorized industries within the forest were considered sampling points and three distance gradient sites viz. Site-1 = Adjacent to industries (0 m), Site-2 = 160 m distance and Site-3 = 320 m distance from industries were designated as treatments. A total of 90 quadrate plots (10 m × 10 m) were taken randomly, of which 30 plots were from each site. Through forest inventory, 46 species (24 trees, 8 shrubs, 5 climbers, and 9 saplings) were recorded from three sites. The study revealed that the stand density and basal area of mature trees (257 stems ha−1 and 8.06 ± 0.60 m2·ha−1) at Site-1 were significantly lower due to diverse industrial operations than other sites. Statistically, all the biodiversity indices of mature trees; Shannon–Wiener’s index (1.72), Simpsons index (0.82), Margalef’s index (1.38), Pielou’s evenness Index (0.39) was found to be lower at proximity to industries. The lowest species richness (12) of all plants was recorded from Site-1. However, the diameter and height distributions of Site-1 comprised young (10–20 cm·dbh) to medium-sized (20.1–30 cm·dbh) trees, while the medium to large sized (>30 cm·dbh) trees was contained at Site-3 in this study. The population structure of tree species at Site-1 also showed a fluctuating curve. Overall, this study highlights that plant ecosystems and tree population structure have declined tremendously due to industrialization. Hence, the current research could be significant for developing the management framework for the disturbed deciduous forest.

The results of the project have a wide practical application in various industries, such as medical institutions and healthcare facilities, large industrial enterprises, in the automotive industry, food, agricultural and livestock industries, as well as in industrial technology, the metallurgical industry; oil and gas industry. In phase interferometric sensors (PID) based on arrays, the optical element itself acts as a sensitive element, which leads to a significant reduction in cost. The OB segment between two gratings is a Fabry-Perot interferometer. Under the influence of deformation and acoustic vibrations, the phase difference of signals from two adjacent Bragg gratings changes. Interferometric sensors are most sensitive to changes in the length of a fiber segment under the influence of external factors. The principle of operation of distributed fiber-optic measuring complexes based on PID in the simplest case (in the case of one PID) is shown in Figure 3.6 and is as follows [4]. Each of the Bragg gratings RB1 and RB2 of the sensor reflects the pulse coming to it from the pulsed laser at the same Bragg wavelength. In this case, the time delay between the reflected pulses is equal to twice the propagation time of light in the sensitive element of the sensor – a fiber enclosed between the gratings. The reflected pulses enter the compensating interferometer (CI), which, in turn, also bifurcates each of them. The delay introduced into the propagation of pulses by the arm 2 of the CI with respect to arm 1 ensures the overlap in time of the pulse reflected from the grating RB1 at the output of arm 2 and the pulse reflected from the grating RB2 at the output of arm 1 and their phase shift by ϕ 0 =π/2.

The article describes the organizational regional structure of industrial waste management in modern Ukraine, which will improve the efficiency of industrial waste management systems and industrial energy facilities in Ukraine. The structure of industrial waste management at different system levels, from the national to the level of an industrial enterprise, is described. The data on the recommendations of the World Health Organization on the emissions of toxicants into the air and the data of the State Statistics Service of Ukraine on the content of the main pollutant gases in air emissions from stationary sources of Ukraine from 1990 to 2018 are presented. The scheme of the negative impact on the environment of emissions of pollutants from stationary sources – production facilities of coal mining and coal processing is characterized. Comparative data on the indicators of the volumes of toxic waste generation at the enterprises of European countries and the heavy industry of Ukraine are given. It is shown that the main sources of the impact of coal processing enterprises and coal processing industries on all spheres of the environment are organized and unorganized dust and gas emissions, discharges of process wastewater and effluents from the surface and from the volumes of dumps and sludge collectors of coal processing plants. As a result of comprehensive research by the authors, a number of coal dumps of concentrating factories in Eastern Ukraine have been studied, migration routes and concentration of rare and heavy metal compounds in the soil near coal dumps have been investigated. Rather stringent standards for the content of hazardous substances in industrial waste require special methods for neutralizing coal sludge before final disposal and / or disposal.of the raw materials used to obtain humic acids. The corresponding equations are given. Keywords: coal sludge, coal preparation plants, coal dumps, sludge collectors, surface runoff, environmental pollution, emissions into the atmosphere, gaseous, liquid and solid toxicants.

Abstract Various materials and technologies are being employed to address the concern of increased wastewater generation. In this work, the synthesis of ZSM-5 (Zeolite Socony Mobil-5) and graphene (GR) composite, their characterisation, and application for the removal of dyes are presented. Two composites of ZSM-5 and GR composites were prepared via the hydrothermal method by varying the loading amount of GR, i.e. 1% and 5%, and labelled as GZ1 and GZ5. The parent and composite materials were characterised using field emission scanning electron microscope (FE-SEM), x-ray diffraction (XRD), diffuse reflectance spectroscopy (DRS), x-ray photoelectrons spectroscopy (XPS), Raman, and Fourier transform infrared (FTIR). The materials were then employed for the photodegradation of methyl orange (MO) dye. The adsorption efficiencies for ZSM-5, GR, GZ1, and GZ5 were found as 0%, 17.8%, 0%, and 16% respectively. According to photodegradation results, the GZ1 composite exhibits the maximum degradation efficiency of 75.3% for 20 ppm of MO, within 180 min of light exposure. The scavenger studies were performed to evaluate the role of active oxygen species (AOS) in the photocatalysis mechanism. All studies were performed with the catalyst dosage of 0.5 mg ml−1. The degradation efficiencies for GR, GZ5, and Z5 were reported as 34.2%, 20.8%, and 17.5%, respectively. On increasing the irradiation time to 240 min, the degradation efficiency of GZ1 reached 92%. The removal efficiencies for MO (7 ppm) and methyl blue (5 ppm) in a 12-ppm dye mixture were observed to be 98% and 97.2% respectively within 180 min of light exposure with GZ1 composite.

Developing cost-effective soft magnetic alloys with excellent mechanical properties is very important to energy-saving industries. This study investigated the magnetic and mechanical properties of a series of (Fe0.3Co0.5Ni0.2)100−x(Al1/3Si2/3)x high-entropy alloys (HEAs) (x = 0, 5, 10, 15, and 25) at room temperature. The Fe0.3Co0.5Ni0.2 base alloy composition was chosen since it has very the smallest saturation magnetostriction coefficient. It was found that the (Fe0.3Co0.5Ni0.2)95(Al1/3Si2/3)5 alloy maintains a simple face-centered cubic (FCC) solid solution structure in the states of as-cast, cold-rolled, and after annealing at 1000 °C. The alloy after annealing exhibits a tensile yield strength of 235 MPa, ultimate tensile strength of 572 MPa, an elongation of 38%, a saturation magnetization (Ms) of 1.49 T, and a coercivity of 96 A/m. The alloy not only demonstrates an optimal combination of soft magnetic and mechanical properties, it also shows advantages of easy fabrication and processing and high thermal stability over silicon steel and amorphous soft magnetic materials. Therefore, the alloy of (Fe0.3Co0.5Ni0.2)95(Al1/3Si2/3)5 holds good potential as next-generation soft magnets for wide-range industrial applications.

Domestic waste contains good organic matter for plant growth. One of the domestic wastes owned by each house is rice washing water. In addition, the tofu industry is also widely found in Indonesia, one of which is Cilacap City. The content of organic matter possessed by the two wastes is a source of plants. To reduce the environment, this waste can be used as raw material for making liquid organic fertilizer (POC). In addition to being environmentally friendly, the raw materials used are also easy to find. This study aims to analyze pH, temperature and levels of C-Organic in liquid organic fertilizer from tofu industrial waste and rice washing water. The manufacture of liquid fertilizer is carried out using the anaerobic method, which utilizes bacteria that are active without oxygen through a fermentation process for 14 days. To determine the effect of adding EM4 and molasses, compositional variations were carried out on samples of liquid fertilizer, namely KO, P1, P2, and P3 with molasses volume sequentially 0 grams, 5 grams, 5 grams, 10 grams. Meanwhile, the volume of EM4 added sequentially is 0%, 5%, 10% and 5%. Measurements of pH and temperature were carried out every 4 days, but measurements of C-Organic were carried out at the beginning and end of the mini-research. The final pH of POC was in accordance with quality standards with KO = 4.5 and P1, P2 and P3 = 4. The final temperature of KO samples was 29.5ᵒC, P1 29ᵒC, P2 and P3 28.5ᵒC. The highest organic-C content was owned by the knockout sample, which was 0.00297. All samples in this mini research are not included in liquid organic fertilizer (POC) but can be classified as nutrients for soil improvement.

These days manufacturing and automobile industries need structures and materials that are good in strength, higher in toughness, low in weight as well as, are more sustainable in comparison to the presently used materials. Innovative materials like hybrid composite materials are gaining a lot of attention in industrial sector. Recent research work depicts that fiber-reinforced hybrid composite can be utilized in several application areas due to their good mechanical and physical characteristics like, high strength, low weight, and higher opposition to corrosion. In this paper, the combined effect of kenaf fibers and coconut shell nanoparticles on coir fibre reinforced epoxy composites has been investigated. Three different combinations of samples with varying content of coconut shell particles as 0, 3, 5 wt% respectively and kenaf fibres as 5, 4, 0 wt% respectively, along with coconut fibers and epoxy matrix, have been used in the research. Results have been calculated for the three samples using six different analytical models. The results are analyzed using Representative Volume Element (RVE) analysis. The mechanical characteristics like Poisson’s ratio, transverse modulus, longitudinal modulus, are evaluated. The outcomes of analytical modelling are in harmony with the results obtained from the RVE analysis. The outcomes of the research show that the hybridization of various fibres in the composite is among the most potent ways to augment the attributes of composite laminates. The incorporation of coconut shell nanoparticles has also seen to increase the elastic properties of the coir kenaf epoxy hybrid nanocomposite.

Abstract Objectives Job exposure matrices (JEMs) are important tools for estimating occupational exposures in study populations where only information on industry and occupation (I&O) are available. JEMs The objective of this work was to create JEMs for solar and artificial ultraviolet radiation (UVR) using a US standardized coding scheme. Methods Using U.S. Census Bureau industry and occupation codes, separate lists of I&O pairs were developed for solar and artificial UVR by a panel of Certified Industrial Hygienists who assigned exposure ratings to I&O pairs with potential exposure. Parameters for exposure included prevalence (P) and frequency (F) for solar UVR and P, F, and intensity (I) for artificial UVR. Prevalence, or percent of all workers employed in an I&O pair who were exposed, was categorically rated: 0 to <1, 1 to <20; 20 to <80, and ≥80. Frequency of exposure, defined by the number of hours per week workers were exposed, was categorically rated: 0 to <5, 5 to <20, 20 to <35, and ≥35 h per week. For artificial UVR only, intensity of exposure was assigned three ratings: low, low with rare excursions, and >low under normal conditions. Discrepant ratings were resolved via consensus. Results After excluding I&O pairs assigned P and F ratings of 0 (solar UVR) and P, F, and I ratings of 0 (artificial UVR) from the JEM, 9206 I&O pairs were rated for solar UVR and 2010 I&O pairs for artificial UVR. For solar UVR, 723 (7.9% of all rated pairs) had ratings in the highest category for P and F; this group included 45 occupations in varied industries. Construction and extraction occupations represented most of the occupations (n = 20; 44%), followed by farming, fishing, and forestry occupations (n = 6; 13%). For artificial UVR, 87 I&O pairs (4.3% of all rated pairs) had maximum ratings for P, F, and I; these comprised a single occupation (welding, soldering, and brazing workers) in diverse industries. Conclusions JEMs for solar and artificial UVR were developed for a broad range of I&O pairs in the US population and are available for use by researchers conducting occupational epidemiological studies.

AbstractStreet food is popular in Eastern Europe, but its diversity and nutritional value are unknown. This study aimed to characterise the street food environment in Chişinău, Moldova, including the vending sites and vendors, food availability and nutritional composition of foods and beverages. All street food vending sites (single point of sale) located in a 1-km buffer centred on the main public market were systematically selected (n 439; n 328 participants). Data on vending sites’ characteristics (mobility, type of physical set-up and access to electricity), operating periods and food availability were collected. Samples of the most commonly available foods of unknown composition were collected (twenty-eight home-made and twenty-four industrial). Macronutrients, Na and K were quantified through chemical analysis. Fruits, beverages and food other than fruits were available in 2·5, 74·3 and 80·8 % of the vending sites, respectively. Among the latter, 66·4 % sold only industrial foods (e.g. pretzels, biscuits, wafers, chocolate and ice cream), 21·5 % only home-made (e.g. savoury and sweet pastries) and 12·1 % both. Home-made foods presented larger serving sizes and energy/serving (median kJ/serving: 1312·5 v. 670·3, P = 0·022); industrial foods were more energy-dense (median kJ/100 g: 1797·0 v. 1269·8, P = 0·002). High SFA, trans-fat and Na contents were found, reaching 10·9 g/serving, 1·4 g/serving and 773·7 mg/serving, respectively. Soft drinks and alcoholic beverages were available in 80·7 and 42·0 % of the vending sites selling beverages, respectively. Concluding, industrial snacks and home-made pastries high in Na and unhealthy fat were frequent in Chişinău. Prevention of diet-related diseases in Moldova may benefit from the improvement of the nutritional profile of street food.

Tujuan dari penelitian ini adalah untuk mempelajari kombinasi proses pendadihan dan sentrifugasi, untuk meningkatkan kecepatan pendadihan dengan menggunakan mesin sentrifugasi kecepatan rendah. Lateks pekat adalah salah satu jenis produk komersial dari industri karet dan masih diproduksi oleh pabrik besar, umumnya dibuat dari mesin sentrifugasi yang biaya investasinya mahal. Hal inilah yang menjadi hambatan bagi industri kecil untuk terjun dalam industri lateks pekat. Untuk memproduksi lateks pekat dari lateks kebun dapat dilakukan dengan proses sentrifugasi putaran tinggi (9000-15000 rpm) dan pendadihan. Lateks dadih adalah lateks pekat, dibuat dengan menggunakan bahan pendadih misalnya CMC dan alginat dalam tangki secara batch selama 1-2 minggu dan proses pendadihan ini kecepatan pemisahannya sangat lambat, sehingga membutuhkan waktu yang lama, akibatnya lateks pekat yang diproduksi dengan teknik pendadihan tidak populer di industri. Dalam penelitian ini sebuah mesin sentrifugasi didisain sederhana dan diharapkan layak digunakan oleh industri kecil menengah, digerakkan dengan motor 5 HP dengan kecepatan maksimum 5000 rpm dan mempunyai kapasitas sekitar 5-6 liter lateks kebun. Untuk memproduksi lateks dadih sekitar 5 liter lateks kebun per jam, bahan pendadih CMC ditambahkan ke lateks kebun dengan dosis 0 sampai 0,2%. Waktu sentrifugasi divariasikan selama 0 sampai 60 menit pada kecepatan 5000 rpm. Hasil penelitian menunjukkan, kondisi optimum untuk memperoleh Kadar Karet Kering di atas 60% diperoleh pada dosis CMC hanya 0,1% dengan waktu sentrifugasi selama 45 menit.

In this research, the epoxy resin was reinforced by (16 layers) of E-glass fiber woven mat (0^°/90^°) with 50% weight fraction and total thickness (3mm). Using 16 layers was due to the absence of any previous study that used this number of layers at this thickness. It is considered a modern study of this style because of the rapid development in modern engineering industries that required lightweight composite materials with high strength and small thickness, which are used in the aerospace industry aviation and other precision engineering industries. The composite material was cut into angles (0^°,5^°,15^°,30^°,45^°) by using CNC water jet culling machine. The tensile test was used to determine the strength of a material ratio to the fiber's direction and by using Vickers hardness to determine the hardness of composite and pure epoxy. The result of pure epoxy (matrix) has the lowest value in tensile strength (σ_UTS), Yong's modulus (E), 0.2% proof yield stress (σ_(0.2%)), modulus of toughness and toughness when compared with a composite material with adding 16 layers of "E-glass fibers". The direction of the fibers with (5^°) of composite has the highest strength, Young's modulus, and 0.2% proof yield stress when compared with (0^°,15^°,30^°,45^°) and pure epoxy. The improvement strength (10.8, 11.8, 9.8, 8.5, 8.3 times) at (0^°,5^°,15^°,30^°,45^°) respectively when compared with pure epoxy. The hardness of composite material improved (220%) relative to pure epoxy. The results show that the best improvement of composite material with fiber's angle (5^°) has the highest results compared with pure epoxy.

In recent years, Russian agriculture has been demonstrating steady positive dynamics, ensuring the growth of its export potential, especially for grain and oilseeds. Their export is of great economic and political importance, since leads to the improvement of the economic and social situation in the agro-industrial complex and in related industries. In this context, Central and South America are considered promising regions, with stable population growth, respectively, the import of agricultural products. While Argentina, Brazil, Uruguay and Chile are among the top ten exporters of food products, at the same time, not all countries in the region fully meet their food needs. Peru, with a population of over 32 million, is one such country. Establishing direct grain deliveries from Russia to this country will, on the one hand, provide an additional grain market, as well as consolidate political interests in the region.

Abstract: Red mud is an industrial waste material generated during production of alumina from bauxite by Bayer process Nowadays, the wastes are not having any industrial applications, so it can be innovatively using these wastes as a raw material in the civil engineering field. Availability of raw material required for manufacturing of cement and production of concrete are limited in nature. So as to overcome this problem it is very much essential to utilize the industrial waste materials and byproducts generated in manufacturing of cement and in concrete construction. Experiments Investigation have been conducted under laboratory condition to assess the strength characteristics of the aluminium red mud.

<p>Since the discovery of 1D nano-object, they are constantly revealing significant physical properties. In this regard, carbon nanotube (CNT) is considered as a promising candidate for application in future nanoelectronics devices like carbon nanotube field effect transistor (CNTFET). In this work, the impact of chirality and gate oxide thikness on the electrical characteristics of a CNTFET are studied. The chiralities used are (5, 0), (10, 0), (19, 0), (26, 0), and the gate oxide thikness varied from 1 to 5 nm.This work is based on a numerical simulation program based on surface potential model. CNTFET Modeling is useful for semiconductor industries for nano scale devices manufacturing. From our results we have observed that the output current increases with chirality increasing.We have also highlight the importance of the gate oxide thickness on the drain current that increases when gate oxide is thin.</p>

The aim of this research is to determine the performance of effective microorganisms (EM) in the composting of mixed food and yard wastes on an industrial scale. Composting parameters such as temperature, moisture content, pH, and the carbon to nitrogen ratio (C:N), as well as the maturity of nitrogen, phosphorus and potassium (NPK), were determined. For this purpose, the type of EM used to accelerate the composting process is Indigenous Microorganism (IMO). The study, which was conducted using the best EM, accelerated the composting process, wherein it only takes approximately 13 weeks for the decomposition process to occur in each heap. The results show that the final temperature for each heap is between 25.57 and 28.03 ͦ C, the percentage of moisture content is between 45.55 and 60.49%, the pH is between 6.81 and 7:41, the ratio of carbon to nitrogen is between 17:1 and 23:1, the NPK value for nitrogen ammonia is between 0 mg/L and 0.56 mg/L, the potassium content is between 2.25 and 3.25 ppm, and the value of phosphorus is between 0.56 and 0.76 ppm. Based on these results, it can be concluded that the quality of the compost produced for all piles is high. Due to the slight differences in parameters between all piles, the effectiveness of EM IMO was not conclusive for either open or closed aerated piles, and further research needs to be done.

Concrete decomposing the organic compounds on because of natural or anthropogenic contaminating sources with photocatalysis existing in its structure is called self-cleaning concrete. In this study, the self-cleaning concrete with industrial waste has been searched from the point of mechanical and physical characteristics. Fly ash, blast furnace slag and sepiolite materials has been used as industrial waste in concrete. Titanium dioxide (TiO2) has been used as photocatalysis material. Specimens with the dimensions 15×15×15 cm were produced using 0 %, 10 %, 20 % and 30 % industrial wastes and 0 %, 1 %, 3 %, 5 % TiO2 by weight instead of cement. Compressive strength, unit weight, and ultrasonic pulse velocity tests were performed on the specimens after 28 days standard cure. Rhodamine-B test in Italian UNI 11259 standard and additional Phenantroquinone test have been performed as self-cleaning test. XRF test also has been made on some of the samples for the chemical analysis. The best photocatalysis performance has showed in the concrete including 5 % TiO2. Test results show that 10 % use of industrial wastes in self-cleaning concrete production is recommended from the point of economic and environmental benefits

In many areas of China, the transformation of the built environment under reform is claiming traditional buildings to create new space for industrial development. The rapidity of growth, urged by the state, characteristically imposes new order on the landscape and reorders the places built by people motivated by different chronological logics, of seasonality, ritual, and the human lifepath. As if just in time to testify on behalf of endangered traditional landscapes, Ronald Knapp has produced China's Old Dwellings, which provides unprecedented coverage of the design and distinctive structural characteristics of regional housing forms.

SUMMARYAnalysis of retentates of milk or whey, ultrafiltered and diafiltered by a pilot batch process with DDS Lab module equipment or (whey only) ultrafiltered by an industrial continuous process showed that nitrogen and ionic contents could not be described mathematically by the use of any value of the retention coefficient K. Analytical data suggested a new concept called segregation for nitrogen and ions in which each of these components consists of a completely permeable fraction and a totally retained fraction that do not exchange. A segregation coefficient Y is then defined as the ratio of the totally retained fraction to the total concentration of the species in the product fed to the equipment. However, this concept does not apply to lactose, where the classic retention concept (K) is retained. The two models are equivalent when K = Y = 0 or K = Y = 1. A first mathematical expression of this model was elaborated for batch ultrafiltration and/or constant volume diafiltration. Another set of equations was established for industrial conditions. These empirical models predict the retentate and permeate composition at any time during processing as well as after drying. The fit of analytical data with computed values was generally fair, with K being 0·1–0·4 in the pilot plant, and 0·1 in the factory. The nitrogen Y value was ∼ 0·95 for milk, and 0·85 for whey. In whey, the calcium Y value varied greatly from 0·06–0·71 depending on the pH, citrate content and heat treatment; in milk it was fairly constant at 0·5 at pH 6·7–5·8.

This work evaluates the incorporation of solid industrial waste such as rice husk ash, bottom ash from mineral coal and ash coming from the washing of sheep wool in Red Ceramic Mass (MRC) composed of clay. These raw materials were collected from industries in the municipality of Bagé-RS, Brazil. Percentages of 0, 5, 10, 20 and 30% of these wastes were added to (MRC) in order to reduce the environmental impacts, both by the clay extraction as well as for waste disposal. The physical tests (Atterberg limits) made with the clay, follow a normative standard. However, the tests made in the formulations served to compare the formulations’ behavior in relation to the clay. In order to verify if the tests proposed in (MRC) and if the formulations have changed significantly the investigated indexes, an Analysis of Variance (ANOVA) was performed. The results generally indicate that there are statistically significant differences, mainly regarding the Plasticity Index (PI) and the Liquidity Limit (LL), as ash was added in the formulations.

Kieserite (MgSO4·H2O) which has great application in recent years, was prepared according to the binary system MgSO4H2O at 80°C and the ternary system MgCl2MgSO4H2O at 25°C, 50°C and 75°C phase diagrams in this research. We reveal that the pure MgSO4·H2O is acquired in the ternary system MgCl2MgSO4H2O at 75°C with MgCl2 (23.966%~37.93%) for the equilibrium time 5~7days. The higher hydrated magnesium sulfate can be obtained in the ternary system with MgCl2 (0~34.52%) at 25°C, (0~35.684%) at 50°C, and (0~23.966%) at 75°C for 5~7days. These results are beneficial for the industrial production by converting MgSO4·7H2O and MgCl2·6H2O which are not fully exploited in salt pans into the useful MgSO4·H2O.
