Implementing Transimpedance Amplifier in 0.35 µm CMOS Technology

The following will be the design mechanism of the transimpedance amplifier and the RF resistor feedback, as well as how it is performed using the 0.35μm CMOS technique. The NMOS transistor has been placed from the conventional transimpedance amplifier as an active feedback contractor. We apply 3.3V voltage and 0.5μA photocurrent works in a circuit. The transimpedance amplifier is proposed after noise reduction, thus quantitating the larger dynamic range and in same time large gain. The simulation work of the transimpedance gain results in both of the single-phase and three-phase transimpedance amplifiers at the voltage gate which is 4.43 cubic meters and 4.39 cubic meters. Then the one-phase power dissipation and three-phase transimpedance amplifier is 602.04 μW and 1.781mW in the voltage gate of 2.0V [1,2]

Material effects in Angus bull and heifer calves fed at different post-weaning nutritional levels

Data were obtained at weaning from 1521 Angus calves sired by 145 bulls during a period of ten years (1969 to 1978). Yearling data were obtained from 1388 Angus calves sired by 135 bulls during a period of nine years (1970 to 1978). The calves supplying these data were raised at the University of Tennessee Plateau Experiment Station, Crossville, Tennessee. The traits recorded on each animal at weaning (average age, 230 days) and at post-weaning (average age, 385 days) were Average Daily Gain, Body Weight, Body Length, Hip Height, Hip Width, Fat Thickness, Hide Thickness, Heart Girth, Condition Score and Type Score. Post-weaning feeding was on a relatively high forage, low concentration ration. Heifers were fed at a restricted level, as compared to bulls to produce an average daily gain of approximately one pound per day, with limited fat production. All records were adjusted by using constants obtained by least-squares procedures to remove variation due to differences in age of calf, sex of calf and age of dam. Nested within-year analyses were performed. One model was used to obtain estimates of components of variance due to sire differences, and another model was used to obtain estimates of components of variance due to dam differences. Analyses by the second model were performed after adjusting the data to remove variation due to sire and year differences. The estimate of the component of variance due to differences in maternal influence was calculated as the difference between the estimate of the component of variance due to total variation between dams and the estimate of the component of variance due to sire differences. Results showed maternal influence on average daily gain (ADG) to weaning in bulls to be greater than that on ADG of heifers. Sire differences in all but two traits, average daily gain and hide thickness, were significant (P\u3c0.01) at post-weaning, but at weaning, sire differences were significant (P\u3c0.01) in only four traits: average daily gain, heart girth, condition score and type score. Differences between sires were responsible for a significant portion of the variance in body weight of both bull (P\u3c0.01) and heifer calves (P\u3c0.01), and bull calves were significantly (P\u3c0.01) heavier than heifer calves. The male data were responsible for the increases in maternal variance percentages from weaning to post-weaning with respect to all but two traits in males, average daily gain and fat thickness which showed the expected decrease. These two traits are obviously directly affected by nutrient supply. The differences between males and females with respect to changes in relative importance of maternal influence from weaning to post-weaning indicate that females, during the post-weaning period, tend to reflect differences in their individual potential for growth more than do males which, apparently, reflect persisting maternal effects during the post-weaning period. In general, maternal variance percentages are greater in females at weaning and greater in males at post-weaning. Maternal variance is of considerable magnitude in several traits both at weaning and post-weaning. However, specific recommendations as to adjustments to remove maternal variance are not justified at this time

Postharvest quality of papaya fruit (carica papaya)associated with applications of calcium and chitosan

A study was conducted to evaluate calcium and chitosan effects on storage life, anthracnose disease incidence, quality, physiological changes and enzymes activities of papaya. Mature green papaya fruits of colour index 2 were used for conducting the experiments. In the first experiment, papaya fruits were treated with different concentrations of chitosan, 0, 0.5, 0.75 and 1%, and stored at 13±1°C for 28 days. Chitosan concentrations 0.75 and 1% showed the best effect on extending storage life by 26 and 28 days, respectively while maintaining the quality compared with 0.5% and control. However, there was no significant difference between 0.75 and 1% treatments. In the second experiment, calcium at different concentrations 1.5, 2.5 or 3.5% were applied as a postharvest treatment for papaya fruits using vacuum infiltration and dip application techniques. Calcium infiltration at 2.5% significantly extended the storage life up to 26 days and retained the quality better than other treatments. Since, chitosan with its coating ability to retard weight loss of fruits and antifungal property while alcium provides better fruit firmness, a study was conducted using calcium at different concentrations 1.5, 2.5 or 3.5% and chitosan at 0.75% or their combination. From the in vitro experiment, calcium at different concentrations had slight inhibition effects on C. gloeosporioides spore germination but did not show any significant effects on mycelial growth. Chitosan treatment significantly inhibited spore germination and mycelia growth compared to calcium treatments and their control. Calcium at 2.5 in combination with chitosan (0.75%) had significantly better effects on inhibition of spore germination and mycelial growth of C. gloeosporioides compared to calcium individual treatments. Anthracnose disease incidence (%) on papaya fruits was significantly controlled (5.6%) using calcium at 2.5% and chitosan compared with the other treatments. This combined treatment of 2.5% calcium with chitosan 0.75% extended the storage life up to 33 days while retaining the quality of fruits compared with the other treatments. To look at the effect of this combined treatment over different storage intervals, experiment has been conducted. The effectiveness of the treatments was assessed by evaluating their impacts on the quality characteristics during 35 days of storage period. Calcium 2.5% in combination with chitosan 0.75% treatment had better retention of fruits firmness, weight loss, retarding changes in color and preserving chemical characteristics during storage compared to the other treatments. Furthermore, experiment on the physiological and ultrastructures changes and enzyme activities during storage was conducted. The combined treatment of calcium 2.5% and chitosan 0.75% markedly reduced the respiration rate, ethylene production and maintaining the integrity of the waxy cuticle and epidermal cells. Polygalacutronase (PG) degrading enzyme activity was retarded and the induction of defense response of fruits against anthracnose disease was enhanced by eliciting peroxidase enzyme activities (POD)

Elements of myth in the modern theatre, with special reference to current theatre in Oman

This study focuses on the relationship between myth in its classical and modern definition and the theatre, and how the developing Omani theatre can Benefit from western and Arabian experiences in this field. The study shows how myths, around the world, were the first attempt by human beings to think, explain, justify and produce concepts and images. They were the basis on which the first drama was established, and have continued to be a major source of inspiration. The study then explores various modern explanations of myth from the mid nineteenth century, in which myths were classified into various categories and attempts made to study each in isolation. It then illustrates how myths were subsequently studied by anthropologists and psychologists, as manifestations of the individual or collective conscious or unconscious realm, which confirms that myths, despite their outwardly illogical element, carry not fact itself but the essence of the fact. The author clarifies the definition and concept of myth in Islamic and Arabic culture, the meaning of the word in the Holy Quran and the attitude of Islamic and Arab scholars towards it. Consideration is also given to the explanations by modern Arab scholars for the ancient Arabs' lack of concern with myths, in contrast to the cultures of their neighbours.The study sheds light on how the modem mythological, sociological, anthropological, theological and psychological explanations of myth are employed in contemporary theatre and how they have influenced performance and critical theories such as those of Artaud and Archetypal Criticism. It is noted that such theories played an essential role in a number of modern theatrical movements, and consequently concluded that those theories might usefully be applied in developing countries like Oman. Particular attention is given to the theatre in Oman, asserting the importance of its interaction with international theatre at both theoretical and practical levels, especially with those countries, which have strong theatrical traditions. Nevertheless, alongside this is emphasised the importance of employing indigenous sources of heritage and knowledge, such as myths.The study elucidates the role of myths in Oman's culture, in light of historical and geographical factors. It describes how mythology became an integral part of people's lives as a way of thinking about, imagining and explaining different events or phenomena in their lives.It is concluded that theatre should be aware of this fact, and deal with it. This does not mean uncritically accepting superstitions and regressive thinking, which could be harmful, but saving the popular heritage and employing it in such a way that people recognize its advantages and disadvantages, as modern mythological studies suggest, in order to build a close relationship between the theatre and its audience, and to provide the society with new and wider intellectual and aesthetic understanding of their existing myths, for the Benefit of both theatre and society

The Potential Ability of Plaster to Cause Breast Cancer as Indicated by CA15-3 and CEA Antigens in Women Working in Gypsum Factory

Plaster is an important form of gypsum that mainly used in building construction. Breast cancer was investigated among women exposure to the dust of such material. The levels of CA15-3 and carcinoembryonic antigens (CEA) as indicators for breast cancer were measured in the serum of 120 women working in a plaster factory. All of involved women showed a normal level of CEA, while 12.5% of them had moderately elevated levels of CA15-3. In conclusion; plaster dust has no significant effect to cause breast cancer in working women. Moderately high levels of CA15-3 in some of exposed women may relate to liver diseases
