Validation of the Italian version of the Internet Behaviors Scale

Problematic Internet Use (PIU) is a dysfunctional behavior associated with prolonged Internet use, which results of negative impact on different aspects of life. Several studies confirmed these negative effects, unlike others that highlighted the benefits of the Internet on psychosocial well-being. The use of standard, valid and reliable tools for PIU assessment could resolve these disputes and also have relevant clinical implications. This study aims to validate the Italian version of the Internet Behaviors Scale and verify its psychometric properties on our sample. The tool is composed of 38 items grouped three factors: Social aspects, Negative impact and Competence and convenience aspect. The study involved 397 subjects, 257 females (64.7%), 138 males (34.8%) and 2 of other geneder (0.5%, not declared), aged 18 to 31 years old (mean = 20.42; SD = 2,72). Factor analyses consisting of Varimax rotation method, Kaiser normalization, Bartlett’s test of sphericity and internal consistency were performed. The results confirmed the good psychometric properties of the Internet Behaviors Scale - Italian Version. Factor analysis showed the validity of the three factors and satisfactorily explained the total variance. Cronbach’s alpha coefficients indicated high internal consistency for each factor. The use of this tool could be useful in the clinical setting, in order to understand the use of the Internet by users and its impact on psychosocial well-being.
Associations Between Anthropometric Measures and Body Fat Percentage in Iranian Adolescents: a Quantile Regression Analysis

Background: The puerpose of this study was to assess the association between anthropometric measures and skinfold thickness as well as parental obesity and physical activity with body fat percentage (BFP) percentiles using a quantile regression (QR) model within a representative sample of Iranian adolescents. Methods: In this cross-sectional study, 2873 school children (1472 girls) aged 14-20 years old were selected by multi-stage random sampling approach from different areas of two cities of Fars Province in southern Iran. Demographic characteristics, parental history of obesity, physical activity were collected by using a self-reported questionnaire. Height, weight, waist (WC), hip (HC), arm (AC) circumferences, triceps (TST), abdominal (AST), clavicle muscle (CMST) skinfold thicknesses, and BFP were measured. A QR analysis was used to evaluate the association between the obesity measures with BFP at different quantiles.Results: The results of QR models showed that circumference measures and skinfold thicknesses were statistically significant positive associations with BFP across all quantiles (P< 0.05). Among boys, having a history of obesity in mothers associated with higher BFP at the 15th to 95th percentiles (the parameter estimates ranged from 1.9 to 4.9, P<0.05). However, there were statistically significant positive associations between parental obesity with BFP in girls at the 25th to 95th and all percentiles for maternal and paternal obesity, respectively (the prameter estimates ranged 1.6-2.6 and 2.7- 5.6 with P<0.05). Moreover, physical activity negatively associated with the lower BFP at 50th to 95th only in grils (prameter estimates ranged -2.5 to -1.7 with P<0.05). Conclusions: This study revealed that anthropometric measures and SF measures associated with higher BFP at all quantiles in Iranian adolescents. The findings of the study also showed that having a history of parental obesity as well as a high physical activity associated with higher and lower BFP, respectively.
Determination of the heat transfer coefficient distribution

In this paper determination of convective heat transfer coefficient distribution method is presented. The method is based on infrared thermography measurements. Investigations were done in the low speed wind tunnel for the air speed range 1-4 m/s. In order to determine convective heat transfer coefficient, PCB (printed circuit board) with the linear heat source has been used (Fig. 1). It has occurred that simple analytical model is sufficient for determination of heat transfer coefficient distribution.
How the Principles of Green Chemistry Changed the Way Organic Chemistry Labs Are Taught at the University of Detroit Mercy

Abstract Many logistic and instructional changes followed the incorporation of the 12 principles of green chemistry into organic chemistry laboratory courses at the University of Detroit Mercy. Over the last decade, institutional limitations have been turned into green chemical strengths in many areas, including integration of atom economy metrics into learning outcomes, replacing overly toxic equipment and reagents, and modifying matters of reaction scale and type.
MOLECULE PAGE GLUCAGON

In 1907, Michael Lane described his anatomical observations of the pancreatic islets of Langerhans as cells with distinctive anatomical properties versus the earlier theory as those of “exhausted acini”(58). In his characterization of stained hamster pancreatic sections, Lane described the existence of two distinct types of cells within the islet, which he referred to as the large α and smaller β cells (58). Four decades later, Sutherland and de Duve established that the α-cells of the pancreatic islet are the primary source of glucagon (95,96). Initially labeled as a contaminant, the physiological role of glucagon was first described in 1921, when Banting and Best conducted their classical experiments of insulin’s actions. Banting and Best tested their first pancreatic extracts in depancreatized dogs and observed an initial transient rise in blood glucose followed by the insulin-induced hypoglycemia (36). Several years later, Murlin and his colleagues credited this transient rise in blood glucose to a hormone they named “Glucagon” or “Hyperglycemic-Glycogenolytic Factor” (28,36,71). Insights into the regulation of glucagon release came from elegant crosscirculation experiments performed by Foa and his colleagues in the 1950s, showing that hypoglycemia triggered by the injection of insulin in a donor dog induces the release of glucagon, which secreted through the donor blood via a pancreatic-femoral anastomosis causes a hyperglycemic response in a recipient dog (28). Bensley and Woerner added to these observations with their suggestion that glucagon induces liver glycogenolysis and thereby promotes a rise in blood glucose levels (4).
Surface functionalization of polyvinyl chloride by plasma immersion techniques

Abstract In this work we discuss the wettability, chemical composition, surface morphology and optical transmittance of polyvinyl chloride (PVC) samples treated by Plasma Immersion and by Plasma Immersion Ion Implantation. The total pressure of N2 or SF6 was 6.66 Pa, for treatments of 900 s, applied rf power of 25 and 100 W, and the substrate temperature was about 298 K. In PIII, high voltage pulses of -2400 V at a cycle time of 30 µs and a frequency of 300 Hz were used. The wettability of the samples was assessed via contact angle measurements, which indicated either hydrophilicity or hydrophobicity, depending on the plasma composition. X-ray Photoelectron Spectroscopic analysis confirmed strong fluorine attachment to the surface after treatments using SF6 plasmas, and the presence of oxygen after treatments using nitrogen plasmas. Atomic Force Microscopy images showed that the roughness Rrms, depends on the plasma conditions. Optical transmittance in the visible region, T (λ), was increased by plasma immersion. The greatest contact angle observed was 142o (PI cathode), while the highest roughness was 213.2 nm. The highest optical transmittance in the visible region was around to 90% (PI anode).

Assessment of Water Balance at Mayang Watershed, East Java

Mayang Watersheds frequently hit by floods during the rainy season and drought during the dry season. This study aims to assess the water balance by calculating water resource availability and water demand in the Mayang watershed. The Water Evaluation and Planning (WEAP) model was used as the primary tool for the analysis. The supply of water comes only from precipitation. Demand was calculated based on the water demand for irrigation, domestic, urban, industrial, and livestock uses. The unit of time to calculate the water balance is ten days. It means that each month is divided into three-time steps. Analysis of the WEAP is based on the water demand from 2002 to 2019. The results showed that from 3rd December to 1st May, the Mayang river and its tributaries could supply all demand sites up to 100%. However, unmet demand occurs from 2nd May to 2nd December. The highest first unmet demand occurred in October, with 0.67 million m3. The management of water resources, especially in terms of distribution during the rainy season and dry season, must be considered.

Treatment of Marigold Flower Processing Wastewater Using a Sequential Biological- Electrochemical Process

Agriculture is the mainstay of the Indian economy. The agro-based industries produce high volumes of highstrength wastewaters that need to be treated and reused to prevent environmental pollution and water wastage. This study evaluated the performances of a sequential biological-electrochemical process for treating an anaerobically digested effluent of a Marigold flower processing agro-industry. The uniqueness of this wastewater possess a major challenge to its treatment since not many studies have been conducted on this wastewater. The biological treatment was carried out in a Sequential Batch Reactor (SBR). The treated water was further polished in a Continuous Bipolar-mode Electrochemical Reactor (ECR) to remove the residual organics. The anaerobically digested effluent Chemical Oxygen Demand (COD), Dissolved Organic Carbon (DOC), Total Nitrogen (TN), Total Phosphorus (TP) and Total Suspended Solids (TSS) were 5750 ± 991 mg/L, 980 ± 120 mg/L, 692 ± 60 mg/L, 9.7 ± 1.1 mg/L, and 1144 ± 166 mg/L, respectively. A significant level of treatment was achieved in the SBR. The combined system was able to remove 79% of COD, 85% of DOC, 53% of TN, and almost 100% of TP, TSS, and Volatile Suspended Solids (VSS). Several organic compounds belonging to the category of natural plants compound, pesticide, fungicide, etc. were detected in the raw wastewater. Most of the compounds were almost completely removed by the treatment system. The final effluent was almost colorless and free from suspended solids. However, for reuse, the water needs to be further treated in an advanced oxidation process.
Impact of urban mobility on carbon footprint in healthcare centers in Extremadura (Spain)

Abstract Users’ journeys to healthcare centers generate high greenhouse gases (GHG) emissions into the atmosphere. The aim of this work is to calculate the carbon footprint generated by these trips, considering different means of transport and average distances traveled. For this purpose, data corresponding to six rural healthcare centers in Extremadura (Spain), which provide health services to less than 15,000 inhabitants, were collected. Buildings that have been considered had a built-up area between 1,328 and 3,192 m2 and staff’s size ranged from 14 to 38. An average of 400 people was surveyed daily at each healthcare center for 25 random days over one year. Average results are 12.93 kg CO2eq/inhabitant, 50.52 kg CO2eq/m2, 2.97 kg CO2eq/user and 1.08 tCO2eq/worker. Equations for estimating GHG emissions in terms of functional parameters of the healthcare centers were also defined. The transportation-to-healthcare-centers breakdown entails travel by foot (33.5%), by single car (40.4%), by shared car (25.1%) and alternative vehicles (less than 1%). Moreover, it was found that sharing vehicles reduce average annual emissions by 20.5%. Finally, savings obtained in different scenarios increasing pedestrian were analyzed. This study allows to identify opportunities to reduce these GHG emissions, which lead to a lower environmental impact of health activity and is useful to calculate carbon footprint due to the operation of a healthcare center.
The Amazon Tall Tower Observatory (ATTO) in the remote Amazon Basin: overview of first results from ecosystem ecology, meteorology, trace gas, and aerosol measurements

The Amazon Basin plays key roles in the carbon and water cycles, climate change, atmospheric chemistry, and biodiversity. It already has been changed significantly by human activities, and more pervasive change is expected to occur in the next decades. It is therefore essential to establish long-term measurement sites that provide a baseline record of present-day climatic, biogeochemical, and atmospheric conditions and that will be operated over coming decades to monitor change in the Amazon region as human perturbations increase in the future. The Amazon Tall Tower Observatory (ATTO) has been set up in a pristine rain forest region in the central Amazon Basin, about 150 km northeast of the city of Manaus. An ecological survey including a biodiversity assessment has been conducted in the forest region surrounding the site. Two 80 m towers have been operated at the site since 2012, and a 325 m tower is nearing completion in mid-2015. Measurements of micrometeorological and atmospheric chemical variables were initiated in 2012, and their range has continued to broaden over the last few years. The meteorological and micrometeorological measurements include temperature and wind profiles, precipitation, water and energy fluxes, turbulence components, soil temperature profiles and soil heat fluxes, radiation fluxes, and visibility. A tree has been instrumented to measure stem profiles of temperature, light intensity, and water content in cryptogamic covers. The trace gas measurements comprise continuous monitoring of carbon dioxide, carbon monoxide, methane, and ozone at 5 to 8 different heights, complemented by a variety of additional species measured during intensive campaigns (e.g., VOC, NO, NO2, and OH reactivity). Aerosol optical, microphysical, and chemical measurements are made above the canopy as well as in the canopy space. They include light scattering and absorption, aerosol fluorescence, number and volume size distributions, chemical composition, cloud condensation nuclei (CCN) concentrations, and hygroscopicity. Initial results from ecological, meteorological, and chemical studies at the ATTO site are presented in this paper.
The Relationship between Green Marketing and Firm Reputation: Evidence from Content Analysis

The purpose of this study is to identify the relationship between firm’s green marketing approach and firm’s reputation improvement among customers. To investigate the object of the current study and provides adequate material to fill a gap in the literature, the current author collected abundant textual data from numerous extant literature. Because the author needed to augment about reliability and validity, textual data from trusted peer-reviewed sources was obtained from numerous databases. Based on a large body of literature, this study suggests that companies have to declare their stand based on their positioning to safeguard their reputation as an entity and that of its products and services. The five components of a company adopting a recognized environmental marketing strategy include product strategy, demand strategy, pricing strategy, distribution strategy, and labeling strategy Thus, firms’ environmental marketing strategies have to be designed with the complete intent of transformation as a solution to enhance their reputation. The current study concludes that the comparison of environmental marketing strategies does not correctly help in ranking the concern in an effective way, and describe the exact details needed in each of the five categories for a company to carry its operations in a sustainable fashion.
