The present research article highlights the metal (Cd, Cu, Pb, Zn and Fe)distribution pattern in the RSPM generated in different hot spot sites located at Kochi, theQueen of Arabian Sea. These sampling sites are categorized under three different zonesas estuarine, riverine, and coastal. Two sampling phases are selected in order to check theconsistency in pollution trend after a two year gap and...
Abstract The aim of this paper is to analysis a multi-stored building [G+5] using STAAD Pro by considering different seismic zones. initially for all type loads (Seismic load, Dead Live load and Wind load) possible combinations are performed as per Indian codes. done under zones which Zone-II, Zone-III, Zone-IV, Zone-V also zone factor values considered IS 1893-2002 (Part-1). By each value incl...
Study on formation mechanism of serrated chip of Ti-6Al-4V titanium alloy based on shear slip theory
Titanium alloy is a typical hard-to-machine metal and lot of serrated chips are often formed in the cutting process. The appearance will not only cause fluctuation force, resulting decline accuracy, but also lead to rapid wear tools. In this study, formation mechanism chip Ti-6Al-4V titanium was investigated by two-dimensional simulation model alloy, which established using Johnson–Cook constit...
Fish serum may reflect status of many biochemical processes in the metabolism. Heavy metals may alter serum biochemical parameters in fishes. In this study, the effect of Cr(VI) and Al(III) in fresh water fish I.Punctatus and neutralize these metals by using dead fungal biomass. Activity of serum enzymes AST, ALT, ALP, CPK, LDH and α – amylase in aluminium and chromium exposed fish. The above s...
An adaptive fuzzy control scheme is studied in this paper for the directcurrent (DC) motor systems with dead-zone input. The fuzzy logic systems are used to approximate the unknown functions in DC motor and based on the information of the parameters on the dead-zone, an adaptive fuzzy control approach is developed via backstepping design technique. Compared with the existing works for DC motor,...
A 242 VOLUME 116 | NUMBER 6 | June 2008 • Environmental Health Perspectives The Energy Independence and Security Act of 2007 calls for the production of 36 billion gallons of renewable fuels by 2022, including 15 billion gallons of corn-based ethanol, a tripling of current production that would require a similar increase in corn production. Yet scientists are coming to understand that biofuels,...
This paper proposes a nonlinear H∞ controller to control a single link rotary flexible joint robot which has dead zone problem. Dead zone properties are caused by dry friction and gearbox backlashes. The flexibility in setup robot is performed by means of a solenoid spring, which is connected between actuator shaft-out and joint shaft-input in a bilateral connection form. The effect of dead zon...
This study examined the concentration of heavy metal accumulated in the toenail of welders and compared to the concentration of airborne heavy metal exposure in the breathing zone of the welders. Ten selected welders with adequate toenail growth were asked to clip all ten toenails for analysis. The heavy metal concentration in the welder’s breathing zone was collected by using mixed cellulose e...
