Currently, 86% of the energy originates from fossil fuelsforelectricity. These are expected to run out, causing severe environmental damage threatening future generations. The total impact of Small and Medium Enterprises （SMEs） on the economy is significant. Solar cells harness the sun＇s energy to generate electricity in an environmentally friendly manner. This study compares silicon solar cells to flexible Organic Photovoltaic solar cells （OPV） for electricity energy for a micro-business in the UK and Iraq. It shows that it is feasible to replace existing fossil fuel sources with solar cells in Iraq due to a greater amount of solar radiation striking the earth＇s surface. Flexible solar cells can replace a proportion of the energy requirements in the UK and a larger proportion in Iraq. Using existing 20% efficient solar cells, 28% and 83% of the energy requirements of the microbusiness can be replaced in UK and Iraq respectively. Assuming 20% efficiency for solar cells placed on windows, 74% and 220% of the energy requirements of UK and Kurdistan can be replaced respectively and the surplus stored.

The secondary flow downstream of a triple elbow layout was studied experimentally and numerically to visualize the flow behavior under swirling inlet flow conditions. The inlet swirling condition was generated by a swirl generator, consisting of a rotary pipe and honeycomb assembly. The experiments were carried out in turbulent water flow condition at Reynolds number Re = 1 × 104 and inlet swirl intensity S = 1. Ultrasonic measurements were taken at four locations downstream of the third elbow. The two-dimensional velocity field of the flow field was measured using the phased array ultrasonic velocity profiler technique to evaluate the flow field with separation. Furthermore, a numerical simulation was performed and its results were compared with the experimental data. The numerical result was obtained by solving three-dimensional, Reynolds-averaged Navier-Stokes equations with the renormalization group k-ε turbulence model. The experimental results confirmed that the swirling flow condition modified the size of the separation region downstream of the third elbow. A qualitative comparison between the experimental and CFD simulation results of the averaged velocity field downstream of the third elbow showed similar tendency on reverse flow.

Dehydroepiandrosterone (DHEA), the most abundant adrenal androgen in primates, is also synthesized from cholesterol in the brain. Like testosterone, DHEA induces spine synapse formation in the hippocampus. In female rats, this response is blocked by co-administration of an inhibitor of aromatase, the enzyme responsible for estrogen biosynthesis. In males, by contrast, the hippocampal synaptic response to DHEA is unaffected by treatment with an aromatase inhibitor. We hypothesized that this sex difference might reflect differential dependence of the hippocampal responses on subcortical afferents from the basal forebrain. To test this hypothesis, we examined the effects of unilateral fimbria/ fornix transection (FFX) on DHEA-induced synapse formation in the cornu ammonis 1 (CA1) hippocampal subfield of gonadectomized female and male rats. In ovariectomized females, CA1 spine synapse density after DHEA treatment was reduced by more than 60% ipsilateral to FFX. In males, however, unilateral FFX transection had no effect on spine synapse density after DHEA treatment. These results suggest that sex differences in the dependence on local estrogen biosynthesis of the CA1 synaptic response to androgen may at least in part be the result of sex differences in the relative contributions of afferents to the hippocampus from the basal forebrain.

The present work measured the bulk etch rate (VB?) of solid state nuclear track detector by taking the diameter time measurement of alpha particle in CR-39 detector. The values of the track diameter have been found by using TRACK-TEST program from Yu et al. function and Brun et al. function with different energies of alpha particles. The results showed that the time-diameter (t-d) method gave good results of the bulk etch rate (VB?) and these values were (1.705 and 1.72) μm·hr-1. They showed good agreement with the values measured by using the other methods, and it was a simple method because it required getting diameters of the tracks in the detector with the etching time.

The Dye Sensitized Solar Cell (DSSC) plays an important role because of low material cost, ease of production and high conversion efficiency as compared to other thin-film solar cell technologies. The main objective is to create and find the best configuration of the solar cell based on materials that are inexpensive and highly efficient in solar energy conversion and subsequently test the efficiency of dye sensitized titanium dioxide solar cell. We begin the process with two glass plates coated with Fluorine tin oxide (FTO). Titanium dioxide is applied to the conductive side of one plate and the other plate is coated with graphite. A dye is adsorbed on to the TiO2 layer and then the plates are sandwiched together. A drop of iodide electrolyte is then added between the plates. The tests carried out indoors under a lamp emitting all wavelengths in the visible spectrum were not found to provide consistent data due to substantial heating of the cell. The outdoor tests carried out in natural sunlight exhibited steady voltage at much higher level. Future research will involve the incorporation of quantum dots instead of the organic dye as a sensitizer. Quantum dots have the advantages of providing tunable band gaps and the ability to absorb specific wavelength.
