The pulsed ionizing radiation effect of monolithic operational amplifiers is investigated using a flash X-ray facility. The experimental results show that the pulsed ionizing radiation causes voltage surges in the devices and the output voltage recovers linearly after transient disturbance exhibited by a negative peak and a positive peak. The recovery time depends on the amplitude of the positi...

Results from tests characterizing the performance and radiation hardness of the HS9008RH flash analog to digital convertor (FADC) are presented. These tests were performed primarily to evaluate the suitability of this device for use 1n the GEM Central Tracker at the SSC experiment . Basic performance characteristics and susceptibility of these characteristics to radiation were examined . Perfor...

Samples of food crops (peanut, peeled pistachio, unpeeled pistachio, rice, and corn) and feed (barley, bran, corn) were autoclave-sterilized, and inoculated with 10(6) of spore suspension of an isolate of Aspergillus flavus fungus known to produce aflatoxin B1 (AFB1) . Following a 10-day period of incubation at 27 C to allow for fungal growth, food and feed samples were irradiated with gamma ra...

One of the challenges of designing motors and alternators for use in nuclear powered space missions is accounting for the effects of radiation. Terrestrial reactor power plants use distance and shielding to minimize radiation damage but space missions must economize volume and mass. Past studies have shown that sufficiently high radiation levels can affect the magnetic response of hard and soft...

background: there are many varieties of compounds in chemical and petrochemical wastewater. one of the important members of the chlorophenols (cps) family is ρ-chlorophenol. this pollutant is introduced into the environment through various human activities such as waste incineration, uncontrolled use of wood preservatives, pesticides, fungicides and herbicides, as well as via bleaching the pulp...

An accelerated wear-out of ultra-thin gate oxides used in contemporary deep-submicron CMOS technologies is one of the effects observed in MOSFETs submitted to irradiation with high LET particles [1-5]. The damage introduced in the gate oxide by an impinging ion may in fact act as a seed for further degradation produced by electrons and holes injected at high fields during a subsequent electrica...

Survivin is overexpressed in most human cancers, including pancreatic adenocarcinoma. Expression of survivin is regulated by specificity protein (Sp) proteins and related to resistance to radiation therapy. Tolfenamic acid induces Sp protein degradation in several cancer cell lines. The purpose of this study is to investigate whether tolfenamic acid inhibits survivin expression and sensitizes p...

Cefoperazone belongs to the third generation of cephalosporin antibiotics. It is accumulated in water due its overuse and causes bacterial, environmental, health issues. In this work, efficiency photocatalytic degradation cefoperazone was studied using different types radiation (simulated solar, UV, LED) presence nanomaterials (ZnO TiO2). First, photolytic examined, where UV showed as most effe...
