A smart voltage and current monitoring system for three phase inverters using an android smartphone application

In this paper, a new smart voltage and current monitoring system (SVCMS) technique is proposed. It monitors a three phase electrical system using an Arduino platform as a microcontroller to read the voltage and current from sensors and then wirelessly send the measured data to monitor the results using a new Android application. The integrated SVCMS design uses an Arduino Nano V3.0 as the microcontroller to measure the results from three voltage and three current sensors and then send this data, after calculation, to the Android smartphone device of an end user using Bluetooth HC-05. The Arduino Nano V3.0 controller and Bluetooth HC-05 are a cheap microcontroller and wireless device, respectively. The new Android smartphone application that monitors the voltage and current measurements uses the open source MIT App Inventor 2 software. It allows for monitoring some elementary fundamental voltage power quality properties. An effort has been made to investigate what is possible using available off-the-shelf components and open source software

Extracellular free water and glutathione in first-episode psychosis-a multimodal investigation of an inflammatory model for psychosis.

Evidence has been accumulating for an immune-based component to the etiology of psychotic disorders. Advancements in diffusion magnetic resonance imaging (MRI) have enabled estimation of extracellular free water (FW), a putative biomarker of neuroinflammation. Furthermore, inflammatory processes may be associated with altered brain levels of metabolites, such as glutathione (GSH). Consequently, we sought to test the hypotheses that FW is increased and associated with decreased GSH in patients with first-episode schizophrenia (SZ) compared with healthy controls (HC). SZ (n = 36) and HC (n = 40) subjects underwent a multi-shell diffusion MRI scan on a Siemens 3T scanner. 1H-MR spectroscopy data were acquired using a GSH-optimized MEGA-PRESS editing sequence and GSH/creatine ratios were calculated for DLPFC (SZ: n = 33, HC: n = 37) and visual cortex (SZ: n = 29, HC: n = 35) voxels. Symptoms and functioning were measured using the SANS, SAPS, BPRS, and GSF/GRF. SZ demonstrated significantly elevated FW in whole-brain gray (p = .001) but not white matter (p = .060). There was no significant difference between groups in GSH in either voxel. However, there was a significant negative correlation between DLPFC GSH and both whole-brain and DLPFC-specific gray matter FW in SZ (r = -.48 and -.47, respectively; both p < .05), while this relationship was nonsignificant in HC and in both groups in the visual cortex. These data illustrate an important relationship between a metabolite known to be important for immune function-GSH-and the diffusion extracellular FW measure, which provides additional support for these measures as neuroinflammatory biomarkers that could potentially provide tractable treatment targets to guide pharmacological intervention

Dietary electrolytes are related to mood

Dietary therapies are routinely recommended to reduce disease risk; however, there is concern they may adversely affect mood. We compared the effect on mood of a low-sodium, high-potassium diet (LNAHK) and a high-calcium diet (HC) with a moderate-sodium, high-potassium, high-calcium Dietary Approaches to Stop Hypertension (DASH)-type diet (OD). We also assessed the relationship between dietary electrolytes and cortisol, a stress hormone and marker of hypothalamic&ndash;pituitary&ndash;adrenal (HPA) axis activity. In a crossover design, subjects were randomized to two diets for 4 weeks, the OD and either LNAHK or HC, each preceded by a 2-week control diet (CD). Dietary compliance was assessed by 24 h urine collections. Mood was measured weekly by the Profile of Mood States (POMS). Saliva samples were collected to measure cortisol. The change in mood between the preceding CD and the test diet (LNAHK or HC) was compared with the change between the CD and OD. Of the thirty-eight women and fifty-six men (mean age 56&middot;3 (sem 9&middot;8) years) that completed the OD, forty-three completed the LNAHK and forty-eight the HC. There was a greater improvement in depression, tension, vigour and the POMS global score for the LNAHK diet compared to OD (P &lt; 0&middot;05). Higher cortisol levels were weakly associated with greater vigour, lower fatigue, and higher levels of urinary potassium and magnesium (r 0&middot;1&ndash;0&middot;2, P &lt; 0&middot;05 for all). In conclusion, a LNAHK diet appeared to have a positive effect on overall mood.<br /

FARELO DO MESOCARPO DE BABAÇU NA TERMINAÇÃO DE TOURINHOS: CARACTERÍSTICAS DA CARCAÇA E CORTES SECUNDÁRIOS DO TRASEIRO ESPECIAL

We evaluated carcass characteristics, weight and percentage of prepared commercial cuts of the primal pistol cut (PC) of 30 young crossbred bulls fed diets which included replacement levels (0, 25, 50, 70 and 100% of the dry matter, DM) of corn by babassu mesocarp bran (BMB). The experiment was a completely randomized design with six replicates. Slaughter weight was not affected by treatments. Hot and cold carcass weights decreased linearly (P<.05) at 230 g and 250 g, respectively, for each 1 kg of replacement, and hot carcass yield (HC) decreased by 3.2 g/kg of HC for each 1 kg of DM of BMB in the diet (P<0.05). Subcutaneous fat thickness presented a quadratic (P<.05) response with maximum point estimated by the regression equation of 4.29 mm with 33.3% substitution. The proportion of PC of the carcass increased linearly as levels of BMB in the diet increased (P<.05). The percentage of side cut showed a quadratic response (P<.05), with maximum point estimated with 33.3% substitution. The weight of the prepared commercial cuts of the PC, striploin, knuckle and eye round, and the percentage of tenderloin, topside and shank, were influenced by the diet (P<0.05). There was no change in prepared meat cuts yields of PC (73.22%) (P<.05). The use of babassu mesocarp bran to replace corn in cattle finishing diets does not affect the weight and meat yield of the pistol cut, but decreases linearly hot carcass weight, and subcutaneous fat thickness at replacement levels above 33.3%
