Meandering rivers are common on Earth and other planetary surfaces, yet the conditions necessary to maintain meandering channels are unclear. As a consequence, self-maintaining meandering channels with cutoffs have not been reproduced in the laboratory. Such experimental channels are needed to explore mechanisms controlling migration rate, sinuosity, floodplain formation, and planform morphodyn...

CONTEXT Trust is the cornerstone of the patient-physician relationship. Payment methods that place physicians at financial risk have raised concerns about patients' trust in physicians to act in patients' best interests. OBJECTIVE To evaluate the extent to which methods of physician payment are related to patient trust. DESIGN Cross-sectional telephone interview survey done between January ...

BACKGROUND Pesticide consumption is increasing in Bolivia as well as pest resistance, pesticide poisonings and pollution of the environment. This survey evaluates the training of small holder farmers on pesticide handling and ecological alternatives to reduce the negative pesticide effects. METHOD A baseline survey was performed in 2002 and follow-up surveys in 2004 and 2009. Farmers were sel...

To improve the permeability of sinter packed bed for achieving efficient utilization low-grade iron bearing minerals, effect returned fines embedding on productivity, yield, flame front speed (FFS) in vanadium titanium magnetite (VTM) sintering process, tumble index (TI) sinter, and was clarified. Results indicate that speed, process are all increased to a certain extent after different sizes f...

This work focuses on the B2B interaction between a service requester and a service provider in a healthcare environment. The requester is the primary caregiver responsible for managing the health of a population of patients. When a patient requires advanced care outside the requester’s expertise, the requester refers the patient to a provider and pays for the referral services. Treatment may su...

To achieve the most energy-efficient operation, this brief presents a circuit design technique for separating the power supply voltage (VDD) of flip-flops (FFs) from that of combinational circuits, called the higher voltage FF (HVFF). Although VDD scaling can reduce the energy, the minimum operating voltage (VDDmin) of FFs prevents the operation at the optimum supply voltage that minimizes the ...

PURPOSE As an alternative to the existing fee-for-service (FFS) system, a diagnosis-related group (DRG)-based payment system has been suggested. The aim of this study was to investigate the early results of pediatric appendicitis treatment under the DRG system, focusing on health care expenditure and quality of health care services. PATIENTS AND METHODS The medical records of 60 patients, 30 ...

the present study was conducted in the central region of khyber pakhtunkhwa (kpk), pakistan comprising seven districts: peshawar, charsadda, nowshera, mardan, swabi, kohat and hangu, during 2010. the objective was to analyze the perceived effect of farmer field school (ffs) approach on farmers’ capacity in controlling pre- and post- harvest losses. descriptive statistics were used to analyze th...

We propose radiation-hardened flip-flops (FFs) based on the adaptive coupling FF (ACFF) with low dynamic power and short delay overheads in a 65 nm Fully Depleted Silicon On Insulator (FDSOI) process. We designed four FFs composed of the master latch with PMOS pass-transistors to reduce delay time overheads and the slave latch with stacked transistors for high soft-error tolerance. We evaluated...

In this paper, we discuss solving the DLP over GF (36·97) by using the function field sieve (FFS) for breaking paring-based cryptosystems using the ηT pairing over GF (3 ). The extension degree 97 has been intensively used in benchmarking tests for the implementation of the ηT pairing, and the order (923-bit) of GF (3 6·97) is substantially larger than the previous world record (676-bit) of sol...
