Učinak hranidbe usitnjenim sjemenkama uzgojene crnjike Nigella sativa L. na proizvodnju jaja i njihovu neškodljivost za ljudsku upotrebu.

The effect of Kalongi (Nigella sativa, L.) seeds was studied on the performance of layers and cholesterol contents of their egg-yolks. A total of 96 White-Leghorn birds of 40 weeks of age and at the egg laying stage were randomly divided into 12 experimental units, eight birds in each unit. These units were randomly allotted to four treatments in such a way that each treatment received 3 experimental units. Four test rations were prepared by supplementing a commercial layer-ration with powdered Kalongi seeds at the rates of 0.0, 0.5, 1.0 and 1.5%. Effects of feeding these rations on feed intake, egg production, egg mass, egg shell thickness, Haugh unit, yolk index, blood spots, meat spots and total cholesterol in eggs were determined after a period of 12 weeks. Blood samples of the two birds selected at random from each replicate were taken at 0, 6 and 12 weeks. The serum obtained from these samples was analyzed for total cholesterol, low-density lipoproteins, high-density lipoproteins and triglycerides. Data on feed intake, feed refused and egg production were used to calculate the feed conversion ratio. Results showed that Nigella sativa seeds significantly (P0.05) change in yolk index, blood and meat spots. The Nigella sativa seeds also significantly (P0,05) u odnosu na indeks žumanjka te prisutnost krvnih i mesnih mrlja. U jaja nesilica hranjenih usitnjenim sjemenkama crnjike zabilježena je značajno manja količina (P<0,05) kolesterola. Ustanovljene su i niže razine serumskih triglicerida, lipoproteina niske gustoće i ukupnog kolesterola, dok je razina loipoproteina visoke gustoće bila povišena dodavanjem komercijalne hrane sa sjemenkama crnjike

Effective Utilization of Municipal Solid Waste as Substitute for Natural Resources in Cement Industry

The aim of this study was to evaluate the municipal solid waste (MSW) composition of Peshawar city and its affective utilization for energy purpose in the cement industry. A total 14 days consecutive testing of MSW samples was conducted for winter and summer periods for the purpose of evaluation of the waste composition followed by calculating its heating values. Compliance level of MSW at source was determined which was based upon the questionnaire distribution followed by the financial analysis and feasibility evaluation of the project. The results revealed that the average waste composition of the samples consists of organic waste contents (20.72%), combustible items (37.86%), readily saleable items (20.95%) and other miscellaneous waste items (20.46%). Moreover, the samples were then tested for the evaluation of calorific value and it was found that the heating value of MSW is recorded up to 35513 KJ/Kg whereas; the value for coal is around 38000 KJ/Kg. These findings revealed that the replacement of coal by MSW may be more efficient and might be effectively utilized in the production of cement as the energy production of MSW and coal is nearly same. In addition, the utilization of MSW as a replacement of coal has a great potential of enhancing the service life of the landfills. Besides, NPV analysis of this study revealed that the project is worthwhile to be implemented as it shows high returns regarding financial aspects

BIM Roles and Responsibilities in Developing Countries: A Dedicated Matrix for Design-Bid-Build Projects

Building information modeling (BIM) through data-rich digital representation has revolutionized the architecture, engineering, and construction (AEC) industry. BIM implementation in the AEC industry has noticeably increased over the last decade. Various BIM roles have been discussed in the literature to ease the process of BIM implementation, but the BIM roles related to project delivery methods have not been standardized. Stimulated by this need, this study develops a BIM roles and responsibilities matrix (BIM-R&R) in the context of the design−bid−build (DBB) projects for developing countries. A comprehensive literature review has been conducted, followed by a questionnaire survey comprising 105 responses. The results were analyzed to formulate a BIM-R&R matrix, on which the expert opinion was obtained from the BIM experts. The proposed BIM-R&R matrix describes all the roles and their corresponding responsibilities required along the project life cycle phases of DBB projects. The incorporation of BIM roles in the DBB procurement process will aid in the efficient management of all information and data that may be lost due to the fragmented nature of DBB. BIM roles with enhanced communication and coordination will also help in reducing time and cost overruns while maintaining a high-quality product. This study helps the associated construction industry in its efforts to implement BIM on their projects by providing a method by which to assess which BIM roles are necessary. Moreover, it will provide project and construction managers with a clear understanding of the BIM roles in DBB projects

BIMp-chart — a global decision support system for measuring BIM implementation level in construction organizations

Building Information Modeling (BIM) is recognized as one of the most significant technological breakthroughs in the Architecture, Engineering, and Construction (AEC) industry. The pace of implementation of BIM in AEC has increased during the past decade with an enhanced focus on sustainable construction. However, BIM implementation lags its potential because of several factors such as readiness issues, lack of previous experience in BIM, and lack of market demand for BIM. To evaluate and solve these issues, understanding the current BIM implementation in construction organizations is required. Motivated by this need, the main objective of this study is to propose a tool for the measurement of BIM implementation levels within an organization. Various sets of indexes are developed based on their pertinent Critical Success Factors (CSFs). A detailed literature review followed by a questionnaire survey involving 99 respondents is conducted, and results are analyzed to formulate a BIMp-Chart to calculate and visualize the BIM implementation level of an organization. Subsequently, the applicability of the BIMp-Chart is assessed by comparing and analyzing datasets of four organizations from different regions, including Qatar, Portugal, and Egypt, and a multinational organization to develop a global measurement tool. Through measuring and comparing BIM implementation levels, the BIMp-Chart can help the practitioners identify the implementation areas in an organization for proper BIM implementation. This study helps understand the fundamental elements of BIM implementation and provides a decision support system for construction organizations to devise proper strategies for the effectual management of the BIM implementation process

Integrating BIM in Construction Dispute Resolution: Development of a Contractual Framework

Building information modeling (BIM), through its data-rich digital representation of building elements, has revolutionized the architecture, engineering, and construction (AEC) industry. Facilitating the process of its implementation, several legal aspects of BIM have been discussed and standardized in the published contract systems, but legal provisions for dispute resolution through BIM are yet to be established. With more enhanced use of BIM, there is a need for a dedicated protocol for utilizing BIM in construction dispute resolution. This study aims to identify, analyze, and classify the potential legal aspects for integrating BIM into the construction dispute resolution process and thereby determine the corresponding provisions required in BIM-enabled contracts. Potential legal aspects were extracted through an analysis of published literature, including research papers, FIDIC contracts, and standard BIM contract documents. A questionnaire survey involving 140 respondents was conducted from which the 24 identified legal aspects were validated to be incorporated in BIM contracts as contract provisions. The proposed BIM-DRes framework maps the legal aspects and finalized contractual provisions with the phases of a construction project and highlights the main stakeholders associated with or affected by these aspects. The developed framework was further validated by three experts from the construction industry. This research explores this overlooked area and expands the body of knowledge on BIM-based dispute resolution, setting the ground for the extension of BIM-enabled contracts
