A Critical Review of Hydraulic Fracture Propagation in Shale Gas Reservoirs
Abstract: The successful exploration and development of unconventional shale gas reservoirs was possible with advances in hydraulic fracturing and horizontal drilling. Hydraulic fracture treatments open these natural fractures and create a fracture network in gas shales. However, the fracture propagation is not fully understood as of now. A critical review of hydraulic fracture propagation in shale gas formations is presented in this paper. Effects of pertinent factors on hydraulic fracture propagation …

Utilization of Agricultural Waste for Defluoridation of Water: A Review
Abstract: Fluoride is an essential micronutrient for human health which can be obtained from food items. Excess fluoride is one of the anionic, inorganic contaminants, found predominantly in ground water due to weathering of rocks, geochemical reactions or anthropogenic activity such as disposal of industrial wastewaters, because of which removal of excess fluoride is mandatory. Among various methods used for defluoridation of water, adsorption is widely used. It is more remarkable …

Analysis of Three Types of Quartzite as Coarse Aggregate Material and their Impact on Compressive Strength on Concrete
Abstract: Aggregates are the most important constituents of concrete. They give body to the concrete, reduce shrinkage, enhance strength and effect economy. The quartzite rock available in Delhi is a prominent geological material available in the entire Aravali range. Most of the manufacturing of concrete is going on using quartzite as aggregate material. However, three different categories of quartzite have been classified on the basis of its colour composition namely greyish …

Comparative Study of Soft Soils Characteristics with Cement Waste Dust, Lime Powder and Boiled Rice Water
Abstract: Improvement of soft soil properties and effective pavement system performance of soft soils can be done only by stabilization process. It is an effective method. Jointly or individually, Chemical and/or Mechanical stabilization is done for various soils depending on the nature of that soil. As far as soft soils are concern, they are having reactive nature and so chemical stabilization is the best choice to improve such soil. Mainly, in …

Design and Implementation of PID Controller for Self Balancing Robot
Abstract: AbstractFor control engineers to study, apply and verify different control methods, inverted pendulum is a very good platform. Nearly 90% of the industries use the concept of inverted pendulum like ship balancing against of sea tide and control of rockets, space ships and landing of aero planes. The simple pendulum is stable while hanging downwards, but the inverted pendulum is a genetically unstable system. To make the inverted pendulum a …

Decision–making Model for Road Projects Retendering in Nigeria
Abstract: The failure in securing basic information about project can rock mega investment in road construction. Most road construction projects suffered due to reasons attributed to delays or terminations which prompt project owners to consider retendering option. Effective and efficient decision-making is prerequisite in the retendering of projects and is perceived lacking in most road projects. In order to overcome these challenges confronting road construction project, this paper aims to build …

Acetylcholinesterase and Butyrylcholinesterase Activities in Brain and Plasma of Several Species of Birds in India
Abstract: Since timely acquisition of concurrent controls is not always feasible, development of a reference data of normal cholinesterase (ChE) activities for various wildlife species particularly for birds is necessary to diagnose anticholinesterase exposure. In the present study, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) activities in brain and plasma of several species of birds collected from Ahmedabad, India, during 2005–2007, were determined. Brain AChE activity ranged from 1.24 µmole/min/g in Indian white-backed …
