this study assessed the optimum water need of pepper (capsicum annuum l. cv. california wonder) and the critical irrigation level to be applied in order to achieve a reasonable economic yield in water shortage conditions. in a controlled field experiment involving five different treatments, seasonal evapotranspiration for pepper fluctuated from 89 mm in the severe stress treatment (i0.00) to 1,...

In radiation processes such as a transition radiation, diffraction radiation, etc. based on relativistic electrons passing through or near an opaque screen, the electron self-field is partly shadowed after the screen over a distance of the order of the formation length γλ. This effect has been investigated on coherent diffraction radiation (DR) by electron bunches. Absorbing and conductive half...

The observation that radiation treatment to a local area of the body results in an antitumor effect for tumors distant to the radiation site has been termed the "abscopal effect." To understand the mechanism of this unusual phenomenon, we examined whether the effect was mediated through p53, a protein complex up-regulated in irradiated cells. Non-tumor-bearing legs of C57BL/6 (wild-type p53) an...

electromagnetic radiation emitted by cell-phones is a new health hazard, especially when they are used inside closed metal bodies such as cars, elevators etc. the modern wireless devices like bluetooth further enhance the effect of this radiation. the present studies were taken to get quantitative information about the actual power density levels to which a human brain is exposed inside a vehic...

Plasma outflows from gamma-ray bursts (GRB), pulsar winds, and relativistic jets radiate high energy emission. However, the radiation damping effect is ignored in conventional simulations. In this letter, we study the radiation damping effect on particle acceleration via Poynting fluxes in two-andhalf-dimensional particle-in-cell (PIC) plasma simulation with magnetized electron-positron plasmas...

[1] The interest in solar ultraviolet (UV) radiation from the scientific community and the general population has risen significantly in recent years because of the link between increased UV levels at the Earth’s surface and depletion of ozone in the stratosphere. As a consequence of recent research, UV radiation climatologies have been developed, and effects of some atmospheric constituents (s...

  Today, nuclear medicine has rapidly been developed so that in some cases, plays a unique role in diagnosis but unfortunalty in spite of diagnostic and therapeutic advantages, the term “NUCLEAR” can induce worries in patients and society. In this article, base on new documents, we intend to show that this worries has no scientific basis. To produce a realistic view, ...

Ionizing radiation has been proved a major stress that can induce carcinogenesis. Nuclear DNA is the main target of ionizing radiation, exposure of which is followed by many types of DNA damages. DNA double-strand breaks (DSBs) induced by ionizing radiation are considered the most relevant lesion for mutations and carcinogenesis, and unrepaired or misrepaired DSBs are a serious threat to genomi...
