The within-field spatial distribution of beneficial arthropods was assessed using two-dimensional grids of pitfall traps and suction sampling across two winter wheat fields of 4 and 16 ha, before and after an application of dimethoate. An unsprayed 6 m wide buffer zone was left around half the edge of the larger field. Arthropod numbers fluctuated to varying extents prior to spraying. Two speci...

chromocolonoscopy using indigo carmine increases the detection of colorectal polyps remains controversial. Additional indigo carmine spraying during cap-assisted colonoscopy is expected to improve the detection rate of colon polyps, especially adenomatous polyps. Therefore, this study aimed to evaluate the usefulness of cap-assisted chromocolonoscopy in the proximal colon for routine colonoscop...

While weeds in sugar beet farming reduce crop yield and quality, they also lead to higher labor and material losses. In recent years, in order to eliminate or reduce the damage caused by weeds in sugar beet farming, weed control has gained importance. To this end, various studies have been conducted on robotic weed control by detecting weeds using image processing algorithms and hoeing or spray...

Materials are precious resources. Different methods are employed to protect the material from degradation. Thermal spraying is one of the most effective method to protect the material from wear, high temperature corrosion, stresses and erosion, thus increasing the life of material in use. Detonation gun spraying is one of the thermal spraying techniques known for providing hard, wear resistant ...

The thermal spraying surface engineering industry relies on manual spraying and standard pre-programmed robotic systems. This research presents the completed geometric forward and inverse kinematics solution for a non standard articulated robotic manipulator which includes continuous 360 axis rotation for waist, shoulder and elbow joints with a commercially available joint for tilt and pitch. T...

Variable spraying technology is an important content and developing direction in current plant protection machinery, which can effectively save pesticide and lighten burden of ecological environment in agriculture according to characteristic of spraying targets and speed of aircraft crew. Paper established mathematic model and delivery function of variable spraying system based on designed hard...

In the face of widespread DEP and ASLR deployment, JIT spraying brings together the best of code injection and code reuse attacks to defeat both defenses. However, to date, JIT spraying has been an x86-only attack thanks to its reliance on variable-length, unaligned instructions. In this paper, we finally extend JIT spraying to a RISC architecture by introducing a novel technique called gadget ...

As a vector control program to control Chagas disease in Guatemala, residual spraying of Rhodnius prolixus and Triatoma dimidiata was performed, and its impact was measured in the department of Zacapa. In order to identify infested villages and determine the degree of infestation, a baseline entomological survey to identify municipalities infested with vectors followed by an additional vector s...

BACKGROUND Potential exposure of ground troops in Vietnam to Agent Orange and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) remains controversial despite the passage of 30 years since the Vietnam War. Because of uncertainty over the serum dioxin levels in ground troops at the end of their service in Vietnam, attempts have been made to develop a methodology for characterizing exposure of ground tro...

Inorganic phosphate is determined by a molybdenummethodby using atomic absorption spectrophotometry, on the basis of the observations of Berenblum & Chain (1938) and Zaugg & Knox (1966, 1967). The method permits analysis for calcium in the same sample and can detect 0.1 ,ug of P. The procedure given below is designed for automatic diluters and dispensers and uses 0.2ml of plasma. It is suitable...
