Rehabilitation of Low rise RCC Structure along 9m High Retaining wall

Mumbai is the financial, commercial and entertainment capital of India, facing bigger challenges in accommodating its over growing population day by day. The Mumbai City has population of 18.4 million over its 634 km2 area, ie. Almost 350 ft2/person. This enormous rise in population density has restricted the development to expand vertically. This also, results in growth of major slums, which is almost 62% of the population dwelling in slums. Subsequently, the authorities is in need of a large scaled Slum Sanitation Program, which utilize the scarcely available land for construction of Community Toilet Blocks with involvement of NGO’s and social experts like Tata Institute of Social Sciences. In this paper an attempt has been made to rehabilitate a G+2 public Toilet Block constructed in very densely populated slum along the hill side of Eastern Mumbai Suburb. The structure is recently constructed on the top of 9 m high retaining wall which has faced an incident of failure of old rubble retaining wall, during course of heavy rains at a rate 100mm in an hour. It caused the soil below the foundation to slip off partially. It was indeed a challenging job to retrofit and stabilize the Structure with best possible technology in the critical site as well as climatic conditions. The short-term as well as long term solution was recommended with the limitation of time and the availability of space. The paper presents, the approach to achieve, durable, sustainable - Structural and Geotechnical Solutions, for Rehabilitating the said (G+2) Structure and the 9m high retaining wall

Ethyl 2-{3-[(6-chloro­pyridin-3-yl)meth­yl]-2-(nitro­imino)­imidazolidin-1-yl}acetate

In the title compound, C13H16ClN5O4, the imidazole ring is in a slight envelope conformation. The dihedral angle between the pyridine ring and the four essentially planar atoms [maximum deviation 0.015 (2) Å] of the imidazole ring is 80.8 (1)°. In, the crystal, weak C—H⋯O and C—H⋯N hydrogen bonds are present. In addition, there are weak π–π stacking inter­actions between symmetry-related pyridine rings with a centroid–centroid distance of 3.807 (1) Å

Design And Analysis of Aircraft Wing

This research develops and analyses a general aviation plane. A preliminary representation of the eventual product is used to start the design process for an airplane. Based on a drawing, a design mission profile is utilized to determine the weight. A more advanced approach is used to estimate weight, which employs calculated performance criteria to produce a more exact weight estimate. The wing design has been demonstrated to be a feasible alternative for a similar general aviation aircraft. When traveling through air or other fluids, a wing is a type of fin that provides lift. Airfoils may be observed on the wings, which have a streamlined cross-section, as a result of this. The lift created by a wing is compared to the drag generated by it to determine its aerodynamic efficiency

GenomeTrafac: a whole genome resource for the detection of transcription factor binding site clusters associated with conventional and microRNA encoding genes conserved between mouse and human gene orthologs

Transcriptional cis-regulatory control regions frequently are found within non-coding DNA segments conserved across multi-species gene orthologs. Adopting a systematic gene-centric pipeline approach, we report here the development of a web-accessible database resource—GenomeTraFac ()—that allows genome-wide detection and characterization of compositionally similar cis-clusters that occur in gene orthologs between any two genomes for both microRNA genes as well as conventional RNA-encoding genes. Each ortholog gene pair can be scanned to visualize overall conserved sequence regions, and within these, the relative density of conserved cis-element motif clusters form graph peak structures. The results of these analyses can be mined en masse to identify most frequently represented cis-motifs in a list of genes. The system also provides a method for rapid evaluation and visualization of gene model-consistency between orthologs, and facilitates consideration of the potential impact of sequence variation in conserved non-coding regions to impact complex cis-element structures. Using the mouse and human genomes via the NCBI Reference Sequence database and the Sanger Institute miRBase, the system demonstrated the ability to identify validated transcription factor targets within promoter and distal genomic regulatory regions of both conventional and microRNA genes

Ethyl 3-[(6-chloro­pyridin-3-yl)meth­yl]-2-oxoimidazolidine-1-carboxyl­ate

In the title compound, C12H14ClN3O3, the imidazole ring adopts a half-chair conformation. The dihedral angle between the pyridine and imidazole rings is 70.0 (1)°. In the crystal, the molecules are linked by C—H⋯O inter­actions, forming chains parallel to the c axis

1-[(6-Chloro­pyridin-3-yl)meth­yl]imidazolidin-2-iminium chloride

The title compound, C9H12ClN4 +·Cl−, is a natural metabolic product of imidacloprid [systematic name: (E)-1-(6-chloro-3-pyridyl­meth­yl)-N-nitro­imidazolidin-2-yl­idene­amine] and was obtained by the reduction of the latter using Fe in HCl. The dihedral angle between the pyridine and imidazole rings is 62.09 (12)°. The crystal structure is stabilized by N—H⋯Cl and C—H⋯Cl inter­actions involving the chloride anion. The pyridine N and the chloride atoms are not involved in inter­molecular inter­actions
