Structural Equation Modelling (SEM) Approach On Inappropriate Construction Equipment Delay Factors

The advancement of construction equipment is a trend in the construction industry, with numerous benefits. However, using inappropriate construction equipment causes delays in construction projects, affecting the firm's reputation. A number of research studies on overall delay have been conducted globally. Even so, there is a lack of research on construction delays caused by inappropriate construction equipment. The aim of this paper is to investigate the inappropriate construction equipment delay factors and their effects on the firm's reputation. Based on the issues identified in the focus group interviews and the literature survey, a questionnaire survey was conducted to assess the impact of these factors on the progress of Indian construction projects. The primary constraint was that all 300 responses were collected in person from construction professionals to avoid lethargic responses that could skew the results. Pearson correlation coefficients were used to determine the positive strength of each factor's relationship. A t-test was used to see if there was a significant difference between the respondents' firm categories. Structural Equation Modeling (SEM) was used to validate the effective relationship between the causes of delays due to inappropriate construction equipment and its impact on company's reputation. All of the factors examined by the SEM analysis evidenced that the inappropriate construction equipment factors are correlated among themselves and combined to impact the reputation of the company. Recommendations are made to overcome the inappropriate equipment delay factors. Doi: 10.28991/cej-2021-03091717 Full Text: PD

Surveillance and Securing the Mobile information on Context based approach

Abstract:-Context based Mobile Information Catalog Surveillance is a mobile phone based communication application.The Short Message Service (SMS) allows text-based messages to be send from mobile telephones on a GSM network. .Many applications need the ability to do real-time notification when events occur. Often the people who need to be kept aware of events are in a remote location. Here the same is to giving the notification to the user when ever they want to communicate with their mobile virtually.To find the contact log from the Android mobile devices whenever we required the contact and change the profile mode of the device for our convenient. This application proved to get the recent call logs details when you sent a message to the device. Then you may want to see contact list those which are think from your mind alphabetical contacts you can get from your mobile. And you change the profile mode for your mobile and if you want Switch off your mobile you can. It is used on Business point of view surveillance and Security. Real time example if the user forgot his mobile at his home and context is very important to access the last moment data received by his mobile. Here context is nothing but the surrounding situation. If you need business point of view you need to access the last moment message otherwise to access the recent call logs which may be important or you need to access the contacts in alphabetical order. In that situation you need to give a privacy to your mobile device you can change your mobile to change the profile mode or to lock the screen. If suppose in your mobile is in silent mode you need anybody to want to access your mobile in your mobile surroundings you can change the mobile device into the normal mode.

PHYSICAL AND PHYTO-CHEMICAL EVALUATION OF GLYCYRRHIZA GLABRA LINN (YASHTIMADHU)

Glycyrrhiza glabra Linn (Yashtimadhu) is a perennial herb commonly known as liquorice. The drug is used in many Ayurvedic formulations like Dasamoolarishtam, Aswagandharishtam, Phalasarpighrita, Khadiragulika, Madhuyastyaditaila etc. Ascertaining the identity, genuineness and purity of herbal drugs has an important role in the maintenance of the quality of the drug and its formulations. The present study was undertaken to assess the preliminary Phyto-chemical constituents of the drug. The preliminary phyto-chemical analysis including quantitative data, qualitative chemical analysis, Thin Layer Chromatography, High Performance Thin Layer Chromatography and Atomic Absorption Spectroscopy were determined. The preliminary Phyto-chemical characteristics observed in the herb may help in standardization, identification and in carrying out further research in Glycyrrhiza glabra Linn

Hydrogen peroxide is a diffusible paracrine signal for the induction of epithelial cell death by activated myofibroblasts

Cell‐cell signaling roles for reactive oxygen species (ROS) generated in response to growth factors/cytokines in nonphagocytic cells are not well defined. In this study, we show that fibroblasts isolated from lungs of patients with idiopathic pulmonary fibrosis (IPF) generate extracellular hydrogen peroxide (H2O2) in response to the multifunctional cytokine, transforming growth factor‐β1 (TGF‐β1). In contrast, TGF‐β1 stimulation of small airway epithelial cells (SAECs) does not result in detectable levels of extracellular H2O2. IPF fibroblasts independently stimulated with TGF‐β1 induce loss of viability and death of overlying SAECs when cocultured in a compartmentalized Transwell system. These effects on SAECs are inhibited by the addition of catalase to the coculture system or by the selective enzymatic blockade of H2O2 production by IPF fibroblasts. IPF fibroblasts heterogeneously express α‐smooth muscle actin stress fibers, a marker of myofibroblast differentiation. Cellular localization of H2O2 by a fluorescent‐labeling strategy demonstrated that extracellular secretion of H2O2 is specific to the myofibroblast phenotype. Thus, myofibroblast secretion of H2O2 functions as a diffusible death signal for lung epithelial cells. This novel mechanism for intercellular ROS signaling may be important in physiological/pathophysiological processes characterized by regenerating epithelial cells and activated myofibroblasts.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154383/1/fsb2fj042882fje.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154383/2/fsb2fj042882fje-sup-0001.pd

Removal of PCR Error Products and Unincorporated Primers by Metal-Chelate Affinity Chromatography

Immobilized Metal Affinity Chromatography (IMAC) has been used for decades to purify proteins on the basis of amino acid content, especially surface-exposed histidines and “histidine tags” genetically added to recombinant proteins. We and others have extended the use of IMAC to purification of nucleic acids via interactions with the nucleotide bases, especially purines, of single-stranded RNA and DNA. We also have demonstrated the purification of plasmid DNA from contaminating genomic DNA by IMAC capture of selectively-denatured genomic DNA. Here we describe an efficient method of purifying PCR products by specifically removing error products, excess primers, and unincorporated dNTPs from PCR product mixtures using flow-through metal-chelate affinity adsorption. By flowing a PCR product mixture through a Cu2+-iminodiacetic acid (IDA) agarose spin column, 94–99% of the dNTPs and nearly all the primers can be removed. Many of the error products commonly formed by Taq polymerase also are removed. Sequencing of the IMAC-processed PCR product gave base-calling accuracy comparable to that obtained with a commercial PCR product purification method. The results show that IMAC matrices (specifically Cu2+-IDA agarose) can be used for the purification of PCR products. Due to the generality of the base-specific mechanism of adsorption, IMAC matrices may also be used in the purification of oligonucleotides, cDNA, mRNA and micro RNAs

MAS Simulator: A Laboratory Set Up

Detailed procedure for laboratory set up of Miniature Aerial System (MAS) simulator. MAS have three parts viz., Miniature (unmanned) air vehicle (MAV), wireless communication link and ground control station (GCS). For testing, flying MAV every time is more expensive and not viable. To overcome this problem, a laboratory based Miniature Aerial Vehicle Flight Simulator (MAVFS) has been developed by replicating MAV with hardware and software. Hardware and software used in GCS is similar for both real time application and simulation. It provides three main functions of mission planning/tracking, observing and piloting. GCS controls the MAVFS through a Wireless Communication Link (WCL)
