The present paper studies the use of genetic algorithm to optimize the tuning of the Proportional, Integral and Derivative (PID) controller. Two control criteria were considered, the integral of the time multiplied by the absolute error (ITAE), and the integral of the time multiplied by the absolute output (ITAY). The time variant plant tested is a first-order plant with time delay. We aim at a real time implementation inside a digital board, so, the previous continuous approach was discretized and tested;the corresponding control algorithm is presented in this paper. The genetic algorithms and the PID controller are executed using the soft processor nIOS II in the Field Programmable gate Array (FPgA). The computational results show the robustness and versatility of this technology.

We analyzed the average value of hepatic uptake SUV lean average (SUVlave), acquisition time, age, reason from the study, focal, multifocal and diffuse prostate uptake, analysis of the location of metastases, level of prostate specific antigen (PSA), we describe uptakes of non-prostate origin and focal uptakes in ribs without anatomical representation. ng>RESULTS:ng> The average hepatic SUVlave was 9.7, the acquisition times were variable (52 - 183 minutes) without alterations in the white-background relationship, the most frequent indication for the study was staging, the uptake in ribs without anatomical representation were considered benign with certain characteristics, PET/CT has the ability to detect neoplastic activity with low PSA levels in lymph nodes nd bone metastatic status. ng>COnCLUSIOn:ng> PET/CT with 18F-PSMA has advantages over bone scan and computed tomography of the abdomen and pelvis for the staging of prostate cancer.

Agave americana *** were exposed to different concentrations of ethyl methanesulphonate(EMS)0,15,30,45 and 60 mM and to different times of exposure(2 and 4 h).The viability and capacity of shoot formation were shown to be affected when the callus were exposed to high concentrations(30–60 mM).Only the callus exposed to 15 mM EMS presented shoot formation;the exposure time of two hours produced the largest quantity of shoots regenerated per callus(21 shoots/callus).In order to generate somaclonal variants resistant to Fusarium oxysporum,a selection pressure was applied through of a culture filtrate(CF)of 100 ppm of the *** was made in callus obtained in the treatment with 15 mM EMS during 2 h of *** CF caused oxidation and necrosis in 71.25%of the callus;however,they were capable of generating shoots(3.5 shoots/callus).Molecular markers type RAPD,ISSR and DAMD were used to evaluate the genetic variation arising from the mutations caused by EMS on control plants and 16-month-old somaclonal *** polymorphic information content(PIC)for each one of the initiating groups was:0.28(DAMD),0.09(ISSR)and 0.14(RAPD).DAMD revealed a greater percentage of polymorphism than RAPD and *** bands were detected in the somaclonal *** indicated that the EMS caused genetic variation in the regenerated plants conferring resistance to them against Fusarium oxysporum.

A way to extend operators in spaces of continuous functions to spaces of continuous set_valued functions is proposed. This extension is developed through the Steiner selections of the set_valued functions. Their properties and characteristics of the convergence of sequences of operators of this class are studied. In Part Ⅱ of this series some applications to approximation theory will be shown.

Three green leafy vegetable samples of pumpkin leaves, spinach leaves, and sorrel leaves were collected from three different locations in a farm in Akwanga and were tested for the presence of organophosphorus (OP) compounds. The concentrations of all the pesticide residues in the vegetable samples were determined using gas chromatography with mass spectrometry (gC-MS). The organophosphorus pesticides detected include carbaryl (0.052 mg/kg) in pumpkin, this is below European maximum residues limit (EU MRL) of 0.1 mg/kg, Dimethoate was found in pumpkin (0.165 mg/kg), spinach (0.103 mg/kg) and sorrel (0.250 mg/kg) all above the EU MRL of 0.05 mg/kg. Dichlofenthion was detected in pumpkin (0.308 mg/kg), pirimiphos methyl was detected in pumpkin and spinach (0.428 mg/kg and 0.149 mg/kg respectively), all these were below the EU MRL of 0.5 mg/kg. Chlorpyrifos was found in spinach (0.230 mg/kg) and sorrel (0.192 mg/kg) only spinach was above the EU MRL of 0.2 mg/kg. The pesticide residue Bromophosethyl was detected in all vegetables, pumpkin leaves (0.501 mg/kg), sorrel (1.571 mg/kg) and spinach (7.981 mg/kg) all above the EU MRL of 0.5 mg/kg. The remaining pesticides detected were all below their EU MRL value;these are Ethion found in spinach (0.167 mg/kg), Methyl Parathion in spinach (0.103 mg/kg) and sorrel (0.335 mg/kg). The levels of some of the organophosphorus pesticide residues found in vegetables were above the maximum residue limits (MRLs) set by the European Union. This calls for laws to regulate the use and circulation of such chemicals. Based on the observation made in these studies, it is proposed that more extensive monitoring investigation covering all vegetables part in Akwanga nasarawa state be carried out to find the exact position of pesticide residues.

The first Dense Z-Pinch(DZP)conference,in 1984,marked an attempt to use then-modern pulsed power with a Z-pinch to work toward thermonuclear fusion *** 11thDZP conference inChina is a good time to look back,tocomment on progress since,and to project *** follows is a personal perspective:scattered comments froma sympathetic outsider and one-time *** these 35 years,Z-pinch theory has evolved from little more than cartoons to fully 3D MHD computer simulations,measurements have gone from mostly time-and spatially integrated diagnostics tomonochromatic imaging,highly resolved x-ray spectroscopy,and active laser *** pulsed power generators now drive x-ray-producing Z-pinches that are powerful enough for many applications;thermonuclear fusion may work single-shot in the future.
