Scientific Assessment of Locally and Factory Built 2 KVA Modified Sine Wave Solar Powered Inverters

This paper presents scientific assessment of locally and factory built 2 kvA modified sine wave inverters. A data logger known as DENT ELITE PRO SP which was connected across the two solar inverters to collect relevant data. The captured data were harmonic distortion, voltage and current variation in the outputs of the solar inverters. An integrated circuit (IC) SG3524 was used to generate the necessary pulse needed to drive the MOSFET (3205IRF) to alternate the direct current (DC) supply. The output from the oscillator stage was amplified using power transistor MOSFET. The frequency at which circuit operate is determined with the oscillator stage. There were different points of interception for both current and voltage for both types of inverters over a stipulated period. The assessment summarily showed that the measurements for the factory made inverter range from 226.044V to 230.811V and these values were within the nominal voltage. However, for locally made inverter, the voltage measurements for the period under consideration were within 215.189V and 221.599V and this depicts a slight deviation from the nominal voltage values. The result showed that the factory built inverter is superior to the locally fabricated type and this implies that there should be improvement in the design of oscillating stage and the determination of the drain current of theMOSFET should be accurate.

Optimal Sweep Gas to Blood Flow Ratio (V/Q) for Initiation of Cardiopulmonary Bypass in a Pediatric Patient Population: A Retrospective Analysis.

The optimal setting to achieve a suitable PaCO2 value of 35-45 mmHg upon initiating cardiopulmonary bypass (CPB) in the pediatric population is undefined in the literature. Sweep gas is set upon initiating and modified throughout CPB to reduce potential complications related to compensatory metabolic acidosis or metabolic alkalosis and associated cerebral blood flow fluctuations. This study retrospectively examined 1,077 CPB cases for which PaCO2 values were no less than 30 mmHg and no greater than 50 mmHg on the pre-CPB blood gas result. Through an observation of the results, we attempted to determine the optimal sweep gas setting upon initiating CPB to obtain a physiologic PaCO2 value of 35-45 mmHg. The probability of achieving an optimal PaCO2 value was modeled as a function of the average sweep gas to blood flow ratio during the period before the first blood gas on CPB. The median sweep gas to blood flow ratio (V/Q) was .64 (.51; .76), with a median first PaCO2 value on CPB of 42 mmHg (38.8; 45). A .6 V/Q had an odds ratio (OR) of 1.57 of obtaining a PaCO2 value between 35 and 45 mmHg on the first CPB blood gas when compared with a .4 V/Q (Figure 1Figure 1.Bivariate associations between PaCO2 and the V/Q ratio.

A .9 V/Q had a 1.76 OR when compared with a .4 and a 1.12 OR when compared with .6. Using a .6 V/Q ratio achieved a PaCO2 value within normal physiologic limits with no significant advantage to a higher V/Q ratio overall. However, younger or smaller patients required a higher V/Q to achieve similar probabilities of being within limits and similar PaCO2 values when compared with the older or larger patients.

Custodians of continuity in an era of change : an oral history of the everyday lives of Crown Court clerks between 1972 and 2015

This thesis investigates the life histories of Crown Court clerks between 1972 and 2015, and has uncovered unheard testimonies of the lived world of law. Drawing on 21 oral history interviews, it is posited that the Crown Court clerk was a pivotal player in the legal system during this period and their contribution to the performance of law has been largely neglected. Though they did not enjoy the economic, social and cultural capital of judges and barristers, or play a central role in the construction and determination of legal issues in hearings, they were chiefly responsible for the smooth functioning of the courtroom, and were constantly working to maintain order and facilitate the flow of proceedings. Court clerks can be characterised as stage managers of the courtroom drama in the sense that the onus was upon them to ensure that all the various props and parties were assembled in the courtroom at the right time, and to direct defendants, witnesses and jurors as to where and when to sit, stand, and what to say at the appropriate moment. Moreover, this thesis asserts that alongside judges and barristers, court clerks were active agents in the perpetuation of traditional practices through their use of official and formal codes of dress, speech and behaviour, and can be perceived as custodians of continuity. This finding is particularly interesting in light of scholarly accounts that have identified a period of radical change to the administration of justice following the founding of the new Courts Service in 1972. It is contended that Crown court clerks were not merely complicit in, but strongly supported a highly ritualised performance of justice. In so doing, they contributed towards upholding the authority and legitimacy of the criminal justice system in ways that have been largely unacknowledged.

Twofold pictorial experience, propositional imagining and recognitional concepts: a critique of Walton’s visual make-believe

Kendall Walton has defined pictorial experience as a visual game of make-believe, which consists in imagining our actual seeing the representational prop to be a fictional face to face seeing the represented subject. To maintain a twofold awareness of these two visual aspects while avoiding a phenomenal clash between them, Walton needs to characterise visual make-believe as involving a propositional imagining. Unfortunately, the strategy does not seem to be successful. Whether propositional imagination is taken as a simple descriptive report or as conceptually penetrating our perception, Walton’s account is not able to secure the visual and the twofold character of pictorial recognition.

The sympathetic nervous system mechanism of exendin-4 in respect of modulating T cell- mediated immune response to severe burns in mice

Objective To investigate the potential effect of glucagon-like peptide-1 (GLP-1) analogue exendin-4 (Ex-4) on immune function of T lymphocytes via neuroendocrine modulation mechanism in mice following severe burns. Methods Male BALB/C mice were randomly(ramdam number) divided into thermal injury group (n=50) and sham-thermal group (n=30). The thermal injury model was made by exposing the back skin of 15% total body surface area (TBSA) to 95 ℃ water for 7 seconds, while in sham-thermal model the mice were immersed in 37 ℃ water instead. The expression of GLP-1 receptor (GLP-1R) was determined in sorted CD4+ T cells from normal mice by immunofluorescence method. In ex vivo experiment, the mice were sacrificed at 24 h post-burn, then the mononuclear cells (MNC) from spleen were separated from both groups and cultured in RMPI 1640 with 10%FCS (fetal calf serum) in presence of ConA (concanavalin A, 5 μg/mL). Cells were pretreated with catecholamine receptor antagonist propranolol (prop) for 1 hour, followed by consecutive dose of Ex-4 for another 48 h. In in vivo experiment, prop (30 mg/kg) was i. p. injected 30 minutes before thermal injury, then Ex-4 (2.4 nmol/kg) was injected i. p. immediately after scalding. Mice were sacrificed at 6 h and 24 h after thermal injury, then the serum and the spleens were collected. Results GLP-1R was expressed on splenic CD4+ T cells from normal mice. Ex-4 exerted no marked effect on the functions of T cells in terms of proliferation and IL-2 secretion at all doses examined ex vivo, which was not affected by pretreatment with prop. In vivo, T cell functions were suppressed by Ex-4 in thermal mice (P<0.05), but was restored by pretreatment with prop. Regardless of ex vivo or in vivo, Ex-4 could induce T cells switched to Th2 response (P<0.05). Moreover, the Th2 switch by Ex-4 was greatly potentiated by prop intervention in thermal mice in vivo other than ex vivo. Norepinephrine level was increased and epinephrine was decreased by Ex-4 in thermal mice. Both norepinephrine and epinephrine levels were obviously enhanced by pretreatment with prop. Conclusions Ex-4 can inhibit the proliferation and IL-2 secretion of splenic T lymphocytes through the sympathetic nervous system, however, it might induce Th2 switch from Th cells by acting directly on GLP-1R. Key words: Burn injury; Glucagon-like peptide-1; T lymphocyte; Immune response; Sympathetic nervous system

Rapid diagnosis of nitrogen nutrition status in rice based on static scanning and extraction of leaf and sheath characteristics

Abstract: According to the mechanism of rice growth, if nitrogen deficiency occurs, not only rice leaf but also sheath shows special symptoms: sheaths become short, stems appear light green, older sheath become lemon-yellowish. Nitrogen nutrition status of rice could be identified based on the differences of color and shape of leaf and sheath under different levels of nitrogen nutrition. Machine vision technology can be used to non-destructively and rapidly identify rice nutrition status, but image acquisition via digital camera is susceptible to external conditions, and the images are of poor quality. In this research, static scanning technology was used to collect images of rice leaf and sheath. From those images, 14 color and shape characteristic parameters of leaf and sheath were extracted by R, G, B mean value function and region props function in MATLAB. Based on the relationship between nitrogen content and the characteristics extracted from the images, the leaf R, leaf length, leaf area, leaf tip R, sheath G, and sheath length were chosen to identify nitrogen status of rice by using Support Vector Machine (SVM). The results showed that the overall identification accuracies of different nitrogen nutrition were 94%, 98%, 96% and 100% for the four growth stages, respectively. Different years of data were used for validation, identification accuracies were 88%, 98%, 90% and 100%, respectively. The results showed that additional sheath characteristics can effectively increase the identification accuracy of nitrogen nutrition status and the methodology developed in the study is capable of identifying nitrogen deficiency accurately in the rice.

Conjuring up New Technology - Using Magic Objects in Co-Ideation with Stroke Survivors.

Ideation means to generate ideas, and when involving non-designers in these activities they need to be informed about the scope of the possibilities without limiting their imagination. This is a general challenge, which becomes particularly important when it comes to advanced technology ideation together with participants that may not have in-depth knowledge of technological designs and solutions. In this study, we supported the ideation process by presenting a kit of magic objects (consisting of cards and physical props) to stroke survivors participating in a co-design workshop carried out within the STARR EU project. The kit was seen to generally work well, but improvements are suggested for the introduction, the design of the cards and the number of objects used.

Effects of Adapted Dialogic Reading on Oral Language and Vocabulary Knowledge of Latino Preschoolers at Risk for English Language Delays.

In this single-case design study, we examined the effects of an adapted dialogic reading intervention on the oral language and vocabulary skills of four Latino preschool children who were at risk for English language delays. We used adapted dialogic reading strategies in English and two literacy games that included a rapid naming activity and playing with props to retell the stories in the books. Results indicated improvement in both oral language and vocabulary skill knowledge from baseline to intervention for all children. Children also showed improvement from baseline to intervention in their story retells during generalization probes. Limitations and implications for future research and practice are discussed.
