Starting in the late 1990s, Affymetrix, Inc. produced a commercial system for hybridizing, washing, and scanning microarrays that was designed to be easy to operate and reproducible. The system used arrays packaged in a plastic cassette or chamber in which the prefabricated array was mounted and could be filled with fluid through resealable membrane ports either by hand or by an automated "flui...

A current source converter (CSC) based shunt active power filter (APF) system is designed and implemented to suppress the amplification of low order harmonics at the medium voltage (MV) interface bus between the distribution and transmission systems. Four CSC based APF modules designed at 1.0 Kv are operated in parallel, and connected to the 31.5 kV MV bus via a specially designed coupling tran...

Microbes are the key components of the soil environment, playing important roles during soil development. Soil parent material provides the foundation elements that comprise the basic nutritional environment for the development of microbial community. After 30 years artificial maturation of cultivation, the soil developments of three different parental materials were evaluated and bacterial com...

Introduction: Laryngeal mask airway (LMA) Fastrach was specially designed as a conduit for blind tracheal intubation in anticipated difficult airway and where we do not require neck extension. i-gel is a disposable, cheap supraglottic device with wide bore stem which facilitates direct passage of a conventional polyvinylchloride (PVC) endotracheal tube. Materials and Methods: A total of 80 adul...

Morphological and physiological characteristics of biological soil crusts (BSCs) enhance soil stability and fertility, and influence soil chemistry. However, the effect of BSCs on soil physico-chemical properties may vary depending on taxa (cyanobacteria, lichen, bryophytes) and species, and be susceptible to soil surface disturbance. We examined a wide variety of soil physico-chemical properti...
