Clay soil results in higher crop yield and quality than sandy soil. However, irrigation causes clay to slump easily, increasing compactness decreasing oxygen content. This study investigated the effects of dry seeding wet emergence on microenvironment cotton growth promotion Xinjiang silt loam fields. The experimental design included three aerated non-aerated treatments. showed that decreased d...

The ongoing COVID-19 pandemic currently involves millions of people worldwide. Radiology plays an important role in the diagnosis and management patients, chest computed tomography (CT) is most widely used imaging modality. An automatic method to characterize lungs patients based on individually optimized Hounsfield unit (HU) thresholds was developed implemented. Lungs were considered as compos...

A microbioreactor with a volume of microliters is fabricated out of poly(dimethylsiloxane) (PDMS) and glass. Aeration of microbial cultures is through a gas-permeable PDMS membrane. Sensors are integrated for on-line measurement of optical density (OD), dissolved oxygen (DO), and pH. All three parameter measurements are based on optical methods. Optical density is monitored via transmittance me...

In engineering application, a two-stage biological aerated filter (BAF) has been deployed to achieve the steady nitrogen removal of wastewater from mining area ionic rare earth with low carbon (C/N) ratio. However, cost-efficiency medium and source casts shadow over further development. this study, influences four media (i.e., volcanic, zeolite, quartz, ceramisite) three soluble sources acetate...

an air filter is a significant element of any mechanical ventilation system. however, the importance and performance evaluation of air filters have not been well publicized and related scientific reports are scarce. in this study, a transportable, off-line, air filter-testing unit (the unit) was designed and utilized to simulate the filter housing of a mechanical ventilation system. the unit wa...

In vivo lung micro-computed tomography (micro-CT) is being increasingly embraced in pulmonary research because it provides longitudinal information on dynamic disease processes in a field in which ex vivo assessment of experimental disease models is still the gold standard. To optimize the quantitative monitoring of progression and therapy of lung diseases, we evaluated longitudinal changes in ...
