For the polynomial planar vector fields with a hyperbolic or nilpotent critical point at the origin, the monodromy problem has been solved, but for the strongly degenerate critical points this problem is still open. When the critical point is monodromic, the stability problem or the center- focus problem is an open problem too. In this paper we will consider the polynomial planar vector fields ...

In the current cross-sectional study, we aimed to investigate the presence and severity of "male" depressive symptoms and suicidal behaviors in psychiatric patients with and without a history of child abuse and neglect, as measured by the Childhood Trauma Questionnaire (CTQ), as well as to explore the associations among childhood maltreatment, "male depression" and suicide risk. The sample cons...

This paper first enlists the generic problems of alloy wheel machining and subsequently details on the process improvement of the identified critical-to-quality machining characteristic of A356 aluminum alloy wheel machining process. The causal factors are traced using the Ishikawa diagram and prioritization of corrective actions is done through process failure modes and effects analysis. Proce...

in order to study the effect of grapeguard on quality, quantity and control of storage diseases of grape in cold storage a completely randomized design with 3 replicate was conducted on two cultivators of kolahdari and kajanguri in khorasan agricultural research center. the fruits after harvesting were transferred to the sheltered place. before keeping in cold storage, the temperature of fruits...

One of the most promising concepts being considered for use by the Objective Force of the U.S. Army is an automated Sensor-to-Shooter (STS) network. An STS network is a closed-loop, internal feedback system that links various suites of sensors deployed throughout a 3D battle space to a network of weapons platforms (shooters) using optimized communications pathways. The system decision to fire o...
