The greenhouse’s energy consumption is a major limiting factor for output and development. To address this, it necessary to adopt green low-carbon heating technologies replace traditional fuels. This will not only help conserve but also reduce emissions, thereby improving the thermal environmental conditions agriculture. paper aims research develop vertical heat exchange tube array device speci...

Oxygen, carbon, and strontium isotope variations in vein-filling calcite and quartz cements and their host rocks are used to elucidate the origin, spatial and temporal evolution, and migration pathways of fluids in the detachment Nuncios fold complex, northeastern Mexico. The folded Mesozoic sedimentary sequence contains two regional paleohydrostratigraphic units separated by a unit of low perm...

BACKGROUND A noninvasive system for determining left ventricular (LV) filling pressure may help to improve personalized fluid removal goals in hemodialysis patients. We previously showed that the change in photoplethysmography (PPG) pulse amplitude measured by finger PPG during a Valsalva maneuver correlates with invasively measured left ventricular end-diastolic pressure (LVEDP). This key PPG ...

Ozone is a powerful oxidizing agent which is responsible for more damage to vegetation than any other air pollutant. In this study, leaf growth, photosynthesis, and carbohydrate content were analysed during the seed-filling growth stage of field-grown soybeans exposed to ambient air and 1.2 times ambient ozone concentration using a Free Air Concentration Enrichment (FACE) facility. By contrast ...

A 63-year-old man with a 38 pack-year smoking history presented with four weeks of worsening cough and shortness of breath. He was initially treated for multifocal pneumonia and chronic obstructive pulmonary disease exacerbation. During the hospital stay, the patient became acutely hypotensive. Physical exam revealed a temperature of 97.8 degrees Fahrenheit, heart rate of 92 beats per minute, b...

The mixing dynamics of granular materials immersed in a liquid was experimentally studied in a quasi-2D rotating drum. A DV (SONY DCR-TRV900 NTSC) motion corder analyzer was used to record the motions of granular materials. The effects of interstitial fluid viscosity and filling degree on the mixing index, mixing rate constant, and dynamic repose angle in the rotating drum were investigated and...

INTRODUCTION Spontaneous pneumocephalus without any pathological condition is very rare. We described a patient with spontaneous pneumocephalus probably arising from the relatively enlarged air-filling sphenoid sinus. CASE PRESENTATION A 51-year-old woman admitted Imam Reza Hospital, Mashhad, Iran with a sudden onset of severe headache and nausea without any neurological deficit. Brain comput...
