With increasing knowledge of the coronavirus disease-2019 (COVID-19), we now understand that COVID-19 presents with various extrapulmonary manifestations multi-organ involvement. Involvement central nervous system (CNS) occurs probably via transsynaptic spread or transfer across blood-brain barrier. Hypoxia, immune-mediated injury, and vascular damage are potential mechanisms for CNS manifestations. Headache, dizziness, chemosensory disturbances, such as loss smell, taste, encephalopathy,...

Abstract In this investigation, Jatropha methyl ester (JME) [JME 20% (volume) + diesel 80% (volume)] was used to adjust the engine’s compression ratio (CR 16, 17, 17.5, and 18) fuel injection (IT) in range of 21–25 deg. crank angle (CA) steps 2 before top dead center (BTDC), identify emission profiles engine, where standard CR IT were 17.5 23 CA BTDC. The results reveal that CO UHC obtained be as low 0.03% vol at 75% load, CR18, IT25, 5 ppm full IT25 respectively. NO x rallied from 47 no...

The saying goes as "Necessity is the mother of invention" reflects on exploration ethno-medicaments for diarrhoea diseases in Orissa against prevalence disease this state since history. paper presents a list traditionally used plants India out which about 48% are recorded from itself. history and culture its present scientific well, supports most prevalent.

Blood carboxyhaemoglobin levels were estimated by double wavelength spectrophotometry in non-smoking women living Chandigarh and its environs related to the cooking fuel they used. Twenty nine used kerosene, 28 biomass fuel, 30 liquified petroleum gas; 27 control subjects had not done any for seven days. The concentrations significantly higher using three types of (mean (SEM) concentration 7.49% [corrected] (0.67%) 15.74% (0.83%) 17.16% (0.62%) gas, compared with 3.52% (0.33%) subjects. It...

Lesions of the cerebellum produce deficits in movement and motor learning. Saccadic dysmetria, for example, is caused by lesions posterior cerebellar vermis. Monkeys patients with such are unable to modify amplitude saccades. Some have suggested that effects on eye movements might reflect a more global cognitive deficit lesion. We tested idea studying vermis attention as well saccadic movements, visual motion perception, luminance change detection. four monkeys known control. Attention...

Lesion studies suggest that the oculomotor vermis (OMV) is critical for initiation of smooth-pursuit eye movements (SPEMs); yet, its specific role has remained elusive. In this study, we tested hypothesis vermal Purkinje cells (PCs) may be needed to fine-tune kinematic description SPEM initiation. Recording from identified PCs monkey OMV, observed SPEM-related were characterized by a formidable diversity response profiles with typically only modest reflection movement kinematics. contrast,...

From the inception of commercialization biodiesel, feedstock scarcity is a major issue to be pondered upon in developing countries. In this study, an attempt has been made use abundantly available underutilized high oil content (67% Nahar seed kernel) derived biodiesel compression ignition engine. The experimental investigation on diesel engine reveals slightly reduced brake thermal efficiency and excellent exhaust emissions up 40% blending with conventional fuel. At full load, compared...

This study attempts to use plentiful available high oil content (67% of Nahar seed kernel) non-edible feedstock as a source for powering diesel engine. Various performance and emission characteristics prepared oil–diesel blends (5%, 10%, 20%, 30%, 40%) are analyzed in single cylinder direct injection engine at different load spectrum, order judge the optimum blend, which can be efficiently used 10% blending with fuel has shown reduction hydrocarbon carbon monoxide by 8.64% 8.34%,...

The exhaustible fossil based fuel and its negative impact on the environment, when used in diesel engine has stimulated to search for an alternative source of energy. In this regard, biofuel seems quite viable solution, as it is renewable environmental benign. From last three decades scientists researchers all over world have contributed methods utilize efficiently bio-origin resources. Experimental investigation use biodiesel prepared from vegetable oil also seemed successful encouraging....

This review reports recent developments in solar greenhouse drying systems conjunction with hybrid technological features and their designs, operations, economic implications as well application agro‐food product processing. Solar energy is one of the most efficient renewable sources to be used an alternative fossil fuels. form finest option for space heating electricity generation among available sources. can directly or indirectly dehydrating agricultural nonagricultural products. However,...

Abstract The researchers attract nanofluids due to their improved thermal and physical properties compared the base fluid. colloidal mixture of nanometre-sized particles with conventional fluid is known as nanofluids. Compared single nanofluids, hybrid show better enhancement in thermophysical properties. Combining nanoparticles into host called a nanofluid. preparation nanofluid needs more importance. However, physiochemical mainly depend on stability article aims provide detailed...

This study investigates the effect of compression ratio (CR: 16, 17, standard 17.5, 18) and injection timing (IT: 21°CA, 23, 25°CA) a single cylinder direct diesel engine having power output 3.5 kW at rated speed 1500 rpm fuelled by an optimal Nahar methyl ester blend (NME40). For NME40/CR18, BTE is improved 1.09% EGT lowered 2.98% compared to NME40 settings, full load. The HC, CO, smoke emission decreased for NME40/CR18 about 15.38%, 21.5%, 0.5% setting, whereas it reduced 25.45%, 23.73%,...

In this study, the performance and emission characteristics of a single cylinder four stroke diesel engine have been studied by using Euglena Sanguinea algal biodiesel its various blends (ES10, ES20, ES30, ES40, ES50, ES100). BSFC EGT increase with in concentration diesel. The average BTE dropped 1.4%, 1.97%, 4.3% for ES40 respectively compared to For parameters, reduction CO, HC, smoke was 21.25%, 29.32%, 7.5% 16.9%, 23.69%, 10.11% Slight rise NOX observed which were 7.3%, 10.1%, 14.41%...

This study explores the combustion characteristics of a single cylinder four stroke variable compression ratio direct injection diesel engine run by Nahar biodiesel (BD) and its six different blends (B5, B10, B20, B30, B40, B50).
