BACKGROUND Heat therapy is one of the most popular non-pharmacological treatments for osteoarthritis of the hand. OBJECTIVES To investigate the therapeutic and chemical effects of Hévíz mud on patients with hand osteoarthritis. METHODS We randomly assigned 47 patients with mild-to-moderate hand osteoarthritis to two groups. Patients in group 1 (n=23) received Hévíz mud applied directly to b...

The problem of constructing an adaptive multiuser detector (MUD) is considered for direct sequence code division multiple access (DS-CDMA) signals transmitted through multipath channels. The emerging learning technique, called support vector machines (SVM), is proposed as a method of obtaining a nonlinear MUD from a relatively small training data block. Computer simulation is used to study this...

One of the most effective parameters in economics of open-pit mines is the pit slope angle, so that the slope angle more than the optimum value increases the probability of a large failure in the pit wall and the slope angle less than the optimum value leads to increasing stripping ratio and reducing net present value of mine. Therefore, in this paper, considering the limit equilibrium methods ...

For complex drilling operations with narrow geo-pressure windows, it is not uncommon to have problems with formation fracturing, due to erroneous mud pump management. To assist the driller in managing the circulation, it is possible to limit both the acceleration of the mud pumps whilst changing the flow-rate as well as the actual flow-rate, to avoid generating downhole pressure above the fract...

In uplink block-fading multiple access channel (BFMAC), the advantage of multiuser diversity (MUD) can be taken to achieve higher system throughput. In this letter, with rate constraints for all users and only channel state information available at the receiver assumed, we demonstrate that nonorthogonal multiple access (NOMA) outperforms the counterpart of orthogonal multiple access (OMA) via e...

Earth is one among five elements having an immense impact on human body. It has been adopted as a treatment modality, i.e. mud therapy in naturopathy. It is a simple, cost effective and efficacious treatment used in the treatment of various disorders. Mud is used as a medicine since long as various references are found available in ancient texts indicating its therapeutic uses. Mud has various ...

The air-seeding hypothesis predicts that xylem embolism resistance is linked directly to bordered pit functioning. We tested this prediction in trunks, roots, and branches at different vertical and radial locations in young and old trees of Pseudotsuga menziesii. Dimensions of bordered pits were measured from light and scanning electron micrographs, and physiological data were from published va...

Kick occurrence is a possible event during a drilling process. It is required to be handled immediately using a well control method to avoid blowout, financial losses and damages to the drilling crew. Several methods including driller, wait and weight, and concurrent are applicable in the drilling industry to control a well during a kick incident. In this study, typical well control methods wer...

Multi carrier modulation (MCM) technique is essential for next generation wireless mobile communication system, which achieves high data rate with high spectral efficiency and high flexibility. Orthogonal Frequency Division multiplexing (OFDM) introduces multicarrier concept in Code Division Multiple Access (CDMA) to give rise to novel concept of MC-CDMA system. The OFDM mitigates multiple acce...
