Abstract :

The processes of uranium extraction from uranium-bearing ores using oxidizers and catalysts, uranium sorption from productive solutions on Purolite A500 anionite have been studied. Comparative studies was carried out on leaching of uranium from ores using traditional oxidizing agents: ammonium nitrate, sodium peroxoborate (FGP), iron (III) and using the catalyst "M-1" including manganese, cobalt, nickel, iron in total 0 , 3 g / dm3, a paramagnetic catalyst based on iron - "PM". When using the catalyst "M-1" after 12 hours of the experiment, uranium extraction was 86 mg / dm3. Investigations have been carried out on uranium extraction from the productive leaching solutions in the presence of the M-1 catalyst on the ion exchange anion exchangers Purolite A500 and Ambersep-920 to select the optimum sorbent to maximize the recovery of the useful component from the solution. The possibility of using Purolite A500 and Ambersep-920 anion exchangers for extracting uranium from leach solutions is shown. It has been established that the sorption and capacitance characteristics of Purolite A500 and 2-Ambersep-920 sorbents are approximately equal.

Abstract :

An investigation was conducted to examine the variation trend of some heavy metal and natural radionuclides concentrations in ambient air at cutting and polishing factories in Shack El-Thoban industrial area, Cairo, Egypt. The present work measures the concentration of some heavy metals such as (Nickel (Ni), Copper (Cu), Aluminium (Al), Cobalt (Co) and Sodium (Na)). The heavy metals were chosen based on the types pollution associated with the industry under this investigation.  Natural radionuclides were determined in the dust attached to aerosol particles that collected on filters by a High-Volume Air Sampler after the desired collection period about 1 h.  The activity of deposited dust was measured by γ-spectrometry for total activity and the trace and heavy metal determination on the collected dust filters by ICPMS.  The data were compared to the air quality standards by the World Health Organization Health (WHO), United state environmental protection (USEPA) and Egyptian regulation.  The evaluated concentrations of trace and heavy metals in ambient air had low concentration compared to the standard.  The radioactivity results indicated that most of the measured natural radionuclides fall within the worldwide averages identified by the United Nations Committee on the Effects of Atomic Radiation. The obtained data could be used as reference data for any future use of modelling purposes for the determination of the annual limit on intake (ALI) for long-lived radioisotopes associated with dust.

Abstract :

Neoseiulus californicus (McGregor) is a predatory mite that can control spider mites. The effect of different diets such as, corn pollen, walnut pollen and date pollen along with the two-spotted spider mite (Tetranychus urticae Koch) eggs on life table parameters of the predatory mite was determined on strawberry detached leaves in Petri dishes. The experiments were carried out under laboratory conditions at 27 ± 1°C, 16L: 8D h photo-period and 70 ± 5% RH. Life table parameters were analysed based on age-stage, two-sex life table. There was no significant difference of total longevity among the different diets. The fecundity rate on date pollen (14.21±2.92 eggs) was higher than the other diets tested. The intrinsic rate of increase (r) of the predatory mites fed with date pollen (0.201±0.032 day -1) was higher than the other treatments. Among the three pollens, date pollen was recognized suitable for development and reproduction of N. californicus.

Abstract :

Arsenic (As) contamination in drinking water is a serious environmental and health problem all over the India. Since biosorption is a less consuming, cheap and easy handling technique to remove As from ground water and waste water, so in present work biosorptive behaviour of Syzygium cumini seeds (SCS) biomass in a batch system has been investigated successfully to remove As (III) from ground water and waste water. Maximum percent removal of 69.30 % of As (III) was achieved at pH - 5, adsorbent dose of 0.3 gm, As (III) concentration of 0.2 mg/l, time of 135 minutes, temperature of 40˚Ϲ and agitation speed of 180 rpm. Percent removal after chemical pretreatment was in the order of FeCl3 (75.75) > NaOH (73.70) > HCHO (67.25) > H2SO4 (69.35) > HCl (64.40). Fourier Transmission Infrared Spectroscopy (FTIR) studies of SCS was done before and after biosorption process to establish the functional groups responsible for As (III) adsorption. In case of ground water the % removal by native, FeCl3, and NaOH pretreated biomass was 83.6 %, 88 % and 86 % respectively, while in case of waste water the % removal was 75.26 %, 79.47 %, and 79.47 % respectively. It is concluded that SCS biomass can be effectively used to remove As (III) ion from aqueous solution. Scanning Electron Microscopy (SEM) of SCS biomass before and after biosorption was also done to understand the morphological changes in biomass.

Abstract :

This unbalanced current 3 phase load is a disturbance that can cause damage to the power transformer. The load on each phase difference may result in a decrease in the power quality of the power system (e.g., IEEE and NEMA). Load unbalance on the power traformator causes losses, excess heat on one phase, reduced lifetime and efficiency on the power traformator. This research aims to design and make a prototype monitoring unbalanced 3 phase currents. Arduino microcontroller as the main controller function to read the current value will be displayed on the LCD (Liquid Crystal Display), activates the buzzer and LEDs as an indicator when there is an unbalanced in the current flow  of a predefined value. The experimental results show that the prototype tool when compared to the ampere meter measuring devices can respond to the 3 phase unbalanced with an average error or accuracy of current per phase R = 3.92%, S = 3.44%, and T = the remaining 3.11%.

Abstract :

The present research work has 24 genotypes of cucumber were evaluated to find out their similarities and differences based on numerical traits. The experiment was laid out in Randomized Complete Block Design (RBCD) with two replications. Numerical traits of the genotypes were measured according to the coding criteria specified by European Cooperative Programmed for Plant Genetics Resources (ECPGR) 2008. Data showed great variation for almost all the traits. Maximum germination (67.5%) was observed in genotype Mardan local while minimum germination (17.5%) was recorded in genotype 28295. The genotypes Haripur local and 28293 showed early flowering. Similarly highest yield was observed in USA Poinsett, Dargai local and Mardan local. These genotypes could be chosen for crossing with other genotypes like 28295 and Sialkot selection having low germination rate and low yield to get a better genotype of cucumber with high germination and maximum yield. Correlation analysis represent that yield was positively correlated with fruit length (.523** P≤0.01) and fruit width (.439* P≤0.01). While fruit per plant showed positive significant correlation with vine length. Present findings are applicable in cucumber cultivation in swat and other areas with similar climatic conditions. This will intern help to improve the economic return and revenue generation of the farmers.
