In this research we tried to get an understanding of plastic consumption behavior in a relatively remote area, Pangandaran district Indonesia, especially on teens and young adults to evaluate their environmental awareness. Volunteers were asked to note down their plastic consumption for over 31 days and differentiate it in three different types of plastic waste that are plastic bottles, plastic bags, and plastic packaging. Results showed that plastic consumption in teens and young adults of the Pangandaran District is still inevitable although they are already exposed to the knowledge of plastic waste impacts. The usage accounted for up to 5 plastics per day. A fluctuating pattern of plastic used was found predominantly for three types of plastic waste with the plastic packaging topping the consumption, followed by the plastic bottle and plastic bag. We hypothesized that the idea of plastic detrimental effects is already known in the group, however the plastic consumption still an unavoidable option since there is no choice and straight law enforcement in the district. This putting the teens and young adults of Pangandaran District at the conscious incompetence category, according to the psychological theory of competence.

Public service delivery is an effort to provide the much-expected value for customers or clients by a government-funded organization through the activities, relationship, or interaction between its employees and the people. Public service organizations in Lagos State cannot deliver effective and efficient services without adequate Human Capital Development. This study seeks to examine the relationship between human capital development and public service delivery in Lagos with emphasis on training, performance appraisal, and job enrichment programs; through the lens of human relations theory as popularised by Elton Mayo. The survey research design was used in this study, and data were analyzed using Pearson Moment Coefficient Correlation (through SPSS) at 0.05 level of significance. Findings in this study reveal that efficient service delivery in Lagos State public service organizations, which is supposed to be a function of proper human capital development, has been on a dwindling mode and for more than three decades now, the Lagos State public service organizations have not overcome the challenge of rendering epileptic services to the public. This study concludes that more attention should be paid to the development of human capital in Lagos State public sector for efficient and effective service delivery. It recommends regular training and performance appraisal for the employees in Lagos PSO.

Over the years, the role and appearance of the kitchen have changed. The story of the simplistic kitchen begins before the advent of modern man and continues until the early 20th century, when the concept took on a new meaning, becoming a welcoming room with the introduction of running water, electricity, and gas. Nowadays, we witness a mixture of world cuisines, trying to imitate the specifics of the kitchen even at home. The era is also characterized by a tendency to reduce the time needed to prepare food, a phenomenon that is partly explained by the requirements of professional life, and technical and scientific progress. Due to the progress of the technical sciences, both the design and the arrangement and optimization of the kitchen (as a living space) have become, as expected, in terms of computer technologies, elements that can be accessible to anyone, without thorough specialized knowledge. In this context, this paper aimed to present the transition from realistic housing design - in the form of models and plans - which was the merit of specialists, to the design of the dream home - through computerized assistance - which today is considered a real opportunity for development, which can also be applied to greenhouses. Starting from the kitchen space and going, in turn, through the stages of design, arrangement, and optimization, the aim was to show that the policies and strategies of good practice that are suitable to be adopted can make the kitchen become one with low impact on the environment. This desideratum can be met by an efficient design of the space, by common sense and meticulous arrangement, respectively by optimizing the storage space, the route of the activities carried out and, the energy consumption. Based on the most frequently consulted literature and good practice guides, it was concluded that the kitchen is by far the space with the most significant impact on the environment, and as such a new approach is needed for it to fit within acceptable limits relative to energy consumption, pollution and waste generation.

Soil provides nutrients, water, and growing space for plants, and thus is the basis for life on earth. Soil nutrient availability impacts productivity of terrestrial ecosystems i.e. forest. However, support for this phenomenon in the tropics remains elusive. In this study, the effects of soil properties including texture, organic matter and nutrients on production of Acacia hybrid and A. mangium plantations in Northeast Vietnam were studied. Thirtythree sample plots of 500 m2 (20 m × 25 m) each were established in plantations of 1–14 years old for measuring stem diameter at breast height and height for all Acacia trees. In each plot, a 0–30 cm depth soil sample was taken for analyzing soil texture, organic matter, and nutrients. While allometry was used to estimate standing volume (production) of all measured stems. The results indicated that both species had rapid growth until 8th year after planting, then growth speed decreases as age increasing. The ratio of loam particles in soil controls production of both species, as higher loam ratios lead to lower production in terms of the standing volume. While higher phosphorous availability in the soil will lead to higher production of A. mangium but not A. hybrid. There weren’t any relationships between production and soil nitrogen and potassium for both species. It is concluded that A. hybrid and A. mangium should be logged at the age earlier than 8 years old for pulpwood to maximize production, rapid reinvestment, and benefit return. Fertilizing phosphorus to acacia plantations should be conducted to increase production, while potassium and nitrogen should not be applied.

Chattogram is the second most populated city in Bangladesh. This port city faces a serious threat mainly due to the lack of safe drinking water. This study was conducted for determining drinking water quality of groundwater sources in Chattogram city. The study was performed in the BCSIR laboratory, Chattogram. It was carried out for a period of six months from 1st July, 2018 to 31th December, 2018. Total six water samples were collected from three different locations (Baluchora, C&B colony and Khulshi area). Each sampling location consists of two separate sampling points. Physicochemical parameters of the collected samples like Temperature, pH, Electrical Conductivity (EC), Total dissolved solid (TDS), Hardness, Turbidity and concentration of Cl, As, Mn, Fe, Pb, Cr and Cd were examined. Microbial parameters like Total Coliform (TC) were also measured. All the analyzed parameters compared with BSTI and WHO drinking water quality standards to understand the overall ground water quality status of the study area. The results reveal that water samples in almost all locations were contaminated with microbial contamination and that the range of physico-chemical parameters was not adequate for consumption. Preliminary treatments like boiling, filtering etc are required before using groundwater for drinking and the necessary measures must be taken for a safe alternative source of drinking water.
