The apparently new hadron-like particle ("cygnet") indicated by cosmic ray observations on certain neutron stars is predicted to be a spin 1/2 fermion of magnetic moment and charge 0 and lifetime infinity. This derives from the natural identification of the cygnet with the one hitherto unobserved fundamental fermion of chronometric particle theory, the x or "exon", which plays the role of a qui...

BACKGROUND Her-2/nue positive breast cancer is an aggressive disease with a higher potential of invasion and metastasis. It constitutes around 20% of all the breast cancer cases and even a higher incidence has been reported in Egypt. Agents targeting Her-2 have been shown to be associated with improvement in response rate, disease free and overall survival. DIAGNOSIS Different biomarkers have...

Synthetic nitrogen fertilizer has been a double-edged sword, greatly improving human nutrition during the 20th century but also posing major human health and environmental challenges for the 21st century. In August 2013, about 160 agronomists, scientists, extension agents, crop advisors, economists, social scientists, farmers, representatives of regulatory agencies and nongovernmental organizat...

Despite growing interest in controlled-release N fertilizers (CRNFs) because of their potential for enhancing nitrogen use efficiency (NUE) and economic returns, comprehensive impact on machine-transplanted rice remains to be understudied. To address this gap, here, we present a two-year field experiment that assessed the CRNF using mechanical deep placement fertilization (DPF) cultivation. The...

Enhanced nitrogen use efficiency (NUE) in turfgrass systems comprises several factors, including more efficient uptake and assimilation of applied (N), as well reduced N losses to the environment. The objectives current research were evaluate inter- intraspecific variation parameters two Agrostis species, creeping bentgrass (Agrostis stolonifera L.) velvet canina L.), under field controlled env...

UV-B radiation effects on nutrient concentrations in above-ground organs of maize were investigated at silking and maturity at different levels of applied nitrogen under field conditions. The experiment simulated a 20% stratospheric ozone depletion over Portugal. At silking, UV-B increased N, K, Ca, and Zn concentrations, whereas at maturity Ca, Mg, Zn, and Cu increased and N, P and Mn decrease...

The importance of organic nitrogen (N) for plant nutrition and productivity is increasingly being recognized. Here we show that it is not only the availability in the soil that matters, but also the effects on plant growth. The chemical form of N taken up, whether inorganic (such as nitrate) or organic (such as amino acids), may significantly influence plant shoot and root growth, and nitrogen ...

Ratoon rice (RR) has been regarded as a labor-saving and beneficial production system. Nitrogen (N) surplus reactive N losses (Nr losses) are effective environmental indicators used to evaluate the performance of management. Few studies have assessed Nr for Chinese RR. In this study, RR planting areas were divided into South China (SC), southern part East (SEC), Central (CC), northern (NEC), So...

Chloride (Cl−) is applied in coffee at rates as a “macronutrient” the form of muriate potash (MOP). Potassium (K+) one most demanded nutrients by plant, and MOP used fertilizers production. No scientific evidence shows how Cl− with influences growth, nutrient uptake, nitrogen use efficiency (NUE). In order to address these questions, greenhouse trial over two years field four were conducted. Th...
