Abstract: This paper is on the study of escape chute system. In this paper we describe the types, benefits, limitations of chute assembly. The motto of this paper is rapid evacuation of people from high rise building and many other structures like automobile etc at the time of emergency using these chute escape systems around 400 lives' can be saved within 15-20 minutes. For the convenience and safety of people this system is specially made device offers a fire-proof, high temperature-proof and multi entrance passage for collective escapes at the same time. Nowadays the chute devices for escaping in high rise building become important for collective escape, which is easy to use and runs......

Abstract: Under this study, the combine compressive strength of concrete mortar containing a locally prepared pozzolana of Metakaolin and an adhesive agent to partially replaced Ordinary Portland Cement (OPC) was checked. The material was found to have many properties of the OPC and can pertly replace the cement for some certain required strength. Several specimens were prepared in the proposed research work to study the behavior of fly ash and metakaolin-based geopolymer concrete. Activating agents include sodium hydroxide and sodium silicate. Ordinary Portland cement will thus take the place of native industrial by-products (such as fly ash) and metakaolin. The specimens' mechanical and durability properties were investigated. Microimaging analysis techniques was also used to evaluate the proposed concrete's microstructural properties. Furthermore, a critical review of literature on the behavior of geopolymer........

Abstract: The problem of the Maluku Islands Province are sea and ferry transportation facilities and infrastructure, the city of Ambon as the centre of government, the growth of various aspects of life in Maluku Province is the distribution artery to and from other regencies and cities so that safe, comfortable facilities and infrastructure are needed. Hunimua Port is one of the oldest ports in Ambon City which serves the Hunimua – Waipirit to round-trip route to Seram Island. This study analyses the operational performance of services, utilities and priorities for the development of Hunimua port infrastructure using the Analytics Hierarchy Process method which is reviewed based on the Passenger Service Standards. The results show that the priority of infrastructure development can be carried out on the level of comfort by improving passenger terminal facilities and maximizing the stacking field or waiting area for motorized vehicles before boarding the ship and taking into account the effective time of loading and unloading vehicles on the number of vehicles at the Hunimua port.

Abstract: Over years, considerable attention has been paid to seismic behavior of structures with vibration control systems. Passive, active, semi-active and hybrid control systems have been used in buildings that might be subjected to high seismic activity. Among those devices, Base Isolation (BI) is a passive vibration control system that partially absorbs input seismic energy before it is transmitted to the superstructure. Seismic behavior of structures is influenced by many factors. Among these factors, ground motion characteristics and structural irregularity have dominant effects on the seismic performance. In addition, vertical irregularity of R.C. building may pose high challenge on its behavior and may increase its seismic vulnerability. In present research, four models will be investigated; these models represent regular and vertical irregular R.C buildings with fixed base or base isolation devices.......

Abstract: Flood management system is not effective to contain flood waters in many parts of the country. Many parts of India are prone to flooding. North Bihar is one such part. Yearly floods in Kosi, Gandak, Baghmati, and Mahananda river systems affects millions of people. Silt coming with flood waters in large areas of north Bihar creates the problem of waterlogging to a large extent.
Rising riverbed levels, poor maintenance ofearthen embankments and their unlined canal systems are responsible for waterlogging of vast areas that severely affect the production of agricultural produce. Properly planned and implemented drainage systems are destroyed year after year by devastating floods to further deteriorate the situation. However, restoration and upgrading of drainage networks to improve drainage from these waterlogged regions will improve this alarming situation........

Abstract: In this study, the potential use of a local kaolin in the manufacturing of blended cements was investigated, the material was characterized for its chemical, physical, mineralogical, and thermal properties using various techniques such as X-Ray Fluorescence (XRF), First derivate of Thermogravimetry (DTG), Differential Scanning Calorimetry (DSC), and X-Ray Diffraction (XRD). Then the produced Metakalin (MK) was used to prepare blended cement for subsequent testing, different substitution levels of 10, 20, 30, and 40% of metakaolin were used with an Ordinary Portland cement OPC. The chemical, physical, and mineralogical analysis of sample showed its congruent with other kaolin found, and in use as supplementary cementitious materials, around the world.......

Abstract: Nowadays many water resources are polluted by human activities including household and agricultural wastes and industrial processes. About 90% of the water we use on our daily basis is contaminated in one way or the other and this has a detrimental effect on human and aquatic lives. Here, we aim at the best possible ways of treating this wastewater using five different coagulants and also determining the efficiencies of the coagulants by varying their concentration. This practical was conducted using a conventional jar test apparatus. The sample was collected from an abattoir area very close to a shallowly dug well at Abakpa. 5ml of the coagulant was added to 20ml of the wastewater........

Abstract: In this study, effluent discharged from brewery was collected to assess its impact on the water quality of Niger River, Onitsha. The values of the effluent discharge from brewery were compared with values recorded for its receiving river. Parameters investigated include total suspended solid (TSS), Biological Oxygen Demand (BODs), Chemical Oxygen Demand (COD), pH, Temperature, conductivity and Dissolved Oxygen (Do). ANOVA test was used for the analyses of these parameters, with the exception of the pH, all the parameters measured from the brewery effluent site as well as in the river indicated higher levels than those permitted by the Nigerian industrial standard and WHO........
