Automatic Car Parking System

In the light of number of vehicles consistently rising and parking space is becoming a major issue in urban and semi urban cities so there is a need to design a parking system which will reduce manual work as well reduce the problem of cars parking on streets. The problems associated with parking are common to most of us, we always face difficulty while searching for a safe parking space. This paper attempts to review globally implemented parking management strategies using different technologies. Further by examining a variety of parking management solution from around the world this paper aims to examine the shift in focus of modern parking management strategies. The motivation for this research paper is to identify the positive points of the innovative approaches, which will aid in designing an automatic car parking system.Keywords:Radio Frequency Identification(RFID), (Infrared)IR sensors, microcontrolle

Effect of dietary canola oil level on the growth performance and fatty acid composition of fingerlings of rainbow trout (Oncorhynchus mykiss)

This study evaluated the suitability of canola oil as a source of supplemental dietary lipid for rainbow trout. Triplicate groups of the 30 fingerlings held under identical culture conditions were fed twice daily by iso-nitrogenous, iso-calorific and iso-lipidic diets for eight weeks. Experimental diets consisted of 30.3% protein, 18.7 kJg^-1 energy and 16.7% lipid from fish oil (FO), canola oil (CO) and 1:1 blend of the two oils (FCO). Moisture, ash, protein, lipid, final body weight, condition factor, feed conversion ratio, survival and hepatosomatic indices were not affected by treatments. Specific growth rate and weight gain of fish reared on fish oil diet (FOD) and canola oil diet (COD) were significantly higher than those fed with the fish and canola oils diet (FCOD). Protein efficiency ratio was highest in fish fed with the COD. Whole body fatty acid compositions mirrored those of diet treatments. The highest amounts of HUFAs were detected in fish fed with FOD, which was significantly different from other treatments. In all treatments PUFAs/SFAs and n-6/n-3 ratios were higher than 0.45 and lower than 4, respectively. Our results indicate the fingerlings can be reared on diets in which FO has been replaced with CO, with no significant effects on fish growth performance

Left ventricular geometric patterns and adaptations to hemodynamics are similar in elderly men and women

<p>Abstract</p> <p>Background</p> <p>Common conditions such as obesity and hypertension result in hemodynamic alterations that will induce remodeling of the left ventricle (LV). However, differences between the genders in the relationship of hemodynamics to LV geometry are not well known.</p> <p>The present study aims to investigate differences between the genders in this respect, in a sample of elderly persons.</p> <p>Methods</p> <p>Echocardiography and Doppler was performed in a population-based sample aged 70 - The Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study (n = 922).</p> <p>Hemodynamic patterns obtained by echocardiography and Doppler were evaluated in relation to four LV geometric groups (normal, concentric remodeling, eccentric hypertrophy and concentric hypertrophy).</p> <p>Results</p> <p>No significant difference between the genders was observed regarding the prevalence of the LV geometric groups.</p> <p>Mean values of most evaluated echocardiography and Doppler variables differed between men and women, such as LA, IVS, LVEDD and IVRT, but the relationship of hemodynamic variables to LV geometric groups did not differ between the genders.</p> <p>Conclusions</p> <p>Although mean values of many echocardiographic variables differed between men and women, the LV geometric adaptations to a given hemodynamic load appear similar in both genders.</p

The effect of simultaneous application of nitrogen and copper on yield and steroidal sapogenin production in Trigonella foenum graecum L.

Diosgenin (a steroidal saponin of fenugreek) has long been used as a raw substance for the manufacturing of steroid drugs. In order to evaluate the nutritional effect of different nitrogen (0, 50, 100, 150 and 200 kg ha-1) and copper (0, 10, 20 and 30 kg ha-1) doses on the diosgenin content, growth and yield of fenugreek (var. Ardestan), an experiment was carried out in a factorial arrangement based on complete randomized block design. The diosgenin content in the plant was monitored by a high performance liquid chromatography. Lower doses of copper increased yield, yield component and diosgenin content, but its higher level (30 kg ha-1) had negative effects on the plant yield. The simultaneous application of nitrogen and copper ameliorate the diosgenin production, yield and yield component. The result obtained from correlation and stepwise regression analysis showed that traits such as leaf area index, pods number per plant, and dry weight have significantly direct relation to diosgenin production levels in plants, while dry weight has the highest effect on diosgenin production compared to other traits. According the results, we also can conclude that nitrogen application can decrease copper toxicity in fenugreek in the contaminated soils
