Although fuel spray parameters, such as cone angle and penetration length, are crucial for developing high-efficiency high-performance combustion engines, general models predicting transient characteristics of these parameters have not been suggested. In this study, the cyclopentane at sub- transcritical conditions relevant IC engine rocket injections were experimentally evaluated. A single sim...

Spray deposition and distribution are affected by many factors, one of which is nozzle flow distribution. A two-dimensional automatic measurement system, which consisted of a conveying unit, a system control unit, an ultrasonic sensor, and a deposition collecting dish, was designed and developed. The system could precisely move an ultrasonic sensor above a pesticide deposition collecting dish t...

This research work depends on enhancing the execution of the diesel engine when they utilized bio diesel oil as an optional fuel without real alteration of engine design. It is also required to grow non edible feed stocks in the waste or marginal land of Gujarat. Work goal is to recognize best suitable Bio-Diesel mix by keeping numerous parameters on it. Bio-Diesel mixes will be given credit sc...

INTRODUCTION AND OBJECTIVES Numerous variations of the head-up tilt-table test potentiated with nitrates have been reported. After the administration of nitroglycerin, between 10 and 25 min of continued tilting have been recommended. The aim of this study was to assess the optimal duration of the pharmacological phase of the head-up tilt-table test potentiated with sublingual administration of ...

In this study a new soluble solid curcumin nanoemulsion powder was prepared using spray-drying technology to improve the solubility and bioavailability of curcumin. The liquid nanoemulsion consisted of curcumin, Capryol 90, Transcutol P, and Cremophor RH40. The solid nanoemulsion was prepared by spray-drying the liquid nanoemulsion in laboratory spray dryer, using lactose as solid carrier. The ...

Hand-held spray guns and lances are the most widely used methods of crop protection in greenhouses despite the heavy workload and high risk of operator exposure associated with these techniques (Foqué 2012). These spray application techniques have also proved to be less effective than spray boom equipment under many conditions while the advantages of using vertical boom sprayers compared with u...

Background and study aims It is important to examine the pharynx during upper gastrointestinal endoscopy. Pharyngeal anesthesia using topical lidocaine is generally used as pretreatment. In Japan, lidocaine viscous solution is the anesthetic of choice, but lidocaine spray is applied when the former is considered insufficient. However, the relationship between the extent of pharyngeal anesthesia...

In article number 2002209, Xinyu Tan, Xiaobo Chen, and co-workers demonstrate a fluorine-free superhydrophobic coating that is prepared using various fabrication methods (e.g., dip-coating, doctor-blade painting, spray-brush). It has impressive mechanical (tested by tape peeling, sand impact, sandpaper abrasion), chemical (pH 1.0–14.0), thermal (up to 550 °C for 2 h) stability, durable, long-te...

Spray irrigation is one of the effective techniques in saving water and increasing crop yield. Large-scale linear move spray irrigation systems are widely used in China. However, the traditional go-stop-go driving method causes difficulty in controlling the linear move irrigator. A new control method efficient in operation and the consumption of water, electricity, and labor is needed. Because ...

Three high-pressure liquid injection machines were used to inject isazofos into the root zone of tuff;grass plots to evaluate its potential for control of Hoplolaimus galeatus and Tylenchorhynchus dubius. A Rogers root zone injector delivering isazofos at 2.3 kg a.i./ha through 30 degrees and 60 degrees spray tips at 5,000 psi (3.45 x 10 Pascals) significantly reduced nematode populations at 32...
