The data analyzed are the results of interviews, observations, and document review at the Regional Cooperation Bureau, the Secretariat of DKI Jakarta Province. The results of the study show that from this multi-stakeholder partnership relationship produces various benefits for each party. However, on the partner factor indicator, there are still several obstacles, such as the change of officials in policy-making agencies who do not receive transfer of knowledge from previous officials, so that the partnership process becomes hampered.

Geo-environmental analysis of the groundwater quality in the vicinity of textile industrial zone

The increase in inhabitants and development of advantageous economic behavior undoubtedly leads to escalating water demand for different uses. Improper planning, mismanagement, inappropriate standards and procedure for discharging the industrial effluents are prime causes for deterioration of groundwater quality in industrial zone. The study vicinity is exaggerated by subsurface water quality problem. To evaluate the water quality of aquifer, sixty two samples were collected, analyzed and the results of the data are evaluated according to the standards. Hydro-chemical facies, rock-water process, factor analysis, correlation matrix studies were carried out for assessing the associated hydro-chemical process operating in the progress of salinity concentration. The analysis reveals that water belongs to highly brackish type. In this study zone, groundwater is influenced by water-rock interaction and evaporation process. Factor analysis shows that the groundwater is greatly deteriorated by anthropogenic activities. Based on hyrochemical study, the subsurface water is not fit for domestic purposes.

ICT Use and Its Influence in Family Functioning With Reference to Process and Structure of Families

ICT use in family functioning is an important area to study as the impact changes when technology grows over years. This research analyzed the role of ICT use in process & structure of families using the factors present in Hertlein multitheoretical model. The additional factor ‘family communication pattern’ was introduced and tested along with the process factor to know its importance. The study has taken 756 samples (both parents & children) in Chennai and tested two hypothesis. Structural Equation Model (SEM) was used to analyze the data. The result shows that ICT has influenced the process changes of the families. The structural changes in families are slowly started occurring and that is not as significant as process changes. The added new factor has loaded positively with existing factors shows that family communication is important for family process and thus contributed for theoretical development.

Case Study of Building Information Modeling Implementation in Infrastructure Projects

Building information modeling (BIM) has been advocated as a potential solution to many challenges of asset management, such as missing data, incompatible software, and unclear business process. However, its current implementation in infrastructure projects has only accounted for technology application and digital information delivery without considering system compatibility or information need. More significantly, BIM implementation requires compatible development of various aspects of a business, a gap in which can lead to different implementation levels or even project failure. Limited research is available on the key factors and challenges of BIM implementation in infrastructure projects. Therefore, this study aims to present a case study with particular emphasis on interviews with key stakeholders to explore the main challenges and solutions of BIM implementation. It starts with the development of interview questionnaires based on literature review and feedback from a research team composed of key stakeholders. Interviews were conducted with 37 professionals from stakeholders of the owner, designers, contractors, and software vendors. Four main factors and challenges, along with potential solutions, were identified from content analysis of the interviews: (i) isolation of project phases (process factor), (ii) incompatibility of project technologies and interfaces (technology factor), (iii) unclear definition of requirements and responsibilities of project stakeholders (people factor), and (iv) imperfect information collection and sharing (information factor). The four factors dictate “when,”“how,” and “what” information should be collected and communicated by “whom,” which are mutually interdependent, and focusing on limited factors instead of all four can compromise the successful implementation of BIM.

Copperas as Iron-Based Coagulant for Water and Wastewater Treatment: A Review

Ferrous sulfate, known as copperas, is generated from the titanium dioxide manufacturing industries. This by-product has been used in cement processing, agriculture, animal feed sector, printing industries, and water treatment. The coagulation/flocculation process is one of the treatment processes that can be used in this type of chemical coagulant in treating the water or wastewater sample. Considering the coagulation/flocculation process factor, copperas may be a coagulant that gives high removal efficiency. The main objective of the review is to identify the performance of copperas or a combination of copperas with other treatment or chemicals to unlocking its potential in the coagulation/flocculation process.

Multi-Objective Optimization of Resistance Welding Process of GF/PP Composites

Thermoplastic composites (TPCs) are promising materials for aerospace, transportation, shipbuilding, and civil use owing to their lightweight, rapid prototyping, reprocessing, and environmental recycling advantages. The connection assemblies of TPCs components are crucial to their application; compared with traditional mechanical joints and adhesive connections, fusion connections are more promising, particularly resistance welding. This study aims to investigate the effects of process control parameters, including welding current, time, and pressure, for optimization of resistance welding based on glass fiber-reinforced polypropylene (GF/PP) TPCs and a stainless-steel mesh heating element. A self-designed resistance-welding equipment suitable for the resistance welding process of GF/PP TPCs was manufactured. GF/PP laminates are fabricated using a hot press, and their mechanical properties were evaluated. The resistance distribution of the heating elements was assessed to conform with a normal distribution. Tensile shear experiments were designed and conducted using the Taguchi method to evaluate and predict process factor effects on the lap shear strength (LSS) of GF/PP based on signal-to-noise ratio (S/N) and analysis of variance. The results show that current is the main factor affecting resistance welding quality. The optimal process parameters are a current of 12.5 A, pressure of 2.5 MPa, and time of 540 s. The experimental LSS under the optimized parameters is 12.186 MPa, which has a 6.76% error compared with the result predicted based on the S/N.

The Evolution of the Chernozems in the Central Part of Russia and their Complex Analysis in Modern Conditions

An increasing anthropogenic impact on soils leads to qualitative and quantitative changes in chernozems, the richest soils on Earth. In this regard, the understanding of modern soil-forming processes is undoubtedly relevant because it will allow predicting the future state of not only soils, but also nature as a whole. The methodology for studying the evolution of chernozems is based on a process-factor analysis of genetically conjugated and agrogenic series of chernozems of different taxonomic levels. The objects of the study were system complexes of soil series, including subtypes of virgin, arable, and irrigated chernozems in the central regions of Russia. The data obtained made it possible to identify patterns of variation in the composition and properties of virgin chernozems in a genetically conjugated series at a subtype level and in the series virgin land – arable land – irrigated arable land; we also detected the processes and factors that determine the nature and direction of changes in the composition and properties of chernozems in the studied series and determined the direction of anthropogenic evolution of chernozems. The main provisions of the work conceptually develop the theory of the chernozem-forming process and serve as a theoretical basis for the development of models for the formation of the chernozem profile. Established quantitative and qualitative indicators of humus profiles of chernozems are important diagnostic features in the classification of these soils. The nature and direction of the chernozem evolution disclosed in the work can serve as the basis for long-term forecasting of the state of these soils and the development of a set of measures for their rational use and protection.’’
