viral hepatitis is one of five infectional factors cause early death in all over the world. every day at least one million people die because of viral hepatitis. six hepatitis viruses have been known until now. they are a, b, c, d, e, g, and it is probable that at least two other kinds i.e. f, and h, will be known soon. only hepatitis b is a dna virus, and the others are rna viruses. all viruse...

this paper mainly focused on implementation of aes encryption and decryption standard aes-128. all the transformations of both encryption and decryption are simulated using an iterativedesign approach in order to minimize the hardware consumption. this method can make it avery low-complex architecture, especially in saving the hardware resource in implementing theaes inversesub bytes module and...

In this study, the branch, leaves, flowers, roots and mixed all parts of different nine Euphorbia species were analyzed for their trace element contents by using ICP-MS. The samples were digested by concentrated nitric acid and hydrogen peroxide in a microwave by ICP-MS before the analysis. The accuracy and precision of the method was evaluated by CRM 1573a Tomato Leaves. Trace element contents...

ntimicrobianas empíricas en infecciones producidas por este atógeno. No podemos obviar la posibilidad de colonización de reserorios, pero tampoco podemos descartar la implicación de este icroorganismo en bacteriemias descritas5, dado que algunos atógenos desencadenantes de sepsis, pueden colonizar reservoios cutáneos (port-a-cath) y generar biofilms. Concluimos, que la secuenciación para la ide...

S e presentan dos métodos que se pueden utilizar como alternativas al GWAS para localizar QTLs en ganado. El primero se centra en el análisis de secuencias de homocigosis (runs of homozygosity, ROH) en grupos de animales (p.ej. casos y controles); el segundo es un método de remuestreo basado en la frecuencia de inclusión de los SNP en modelos predictivos. Las ROH se aplicaron a la identificació...

Plants have need for about 18 essential nutrients. Of these essential nutrients, several are classified as trace metals, namely: zinc, iron, manganese, copper, boron, molybdenum, cobalt, and nickel. In addition, other trace metals commonly exist in soil that can be taken up, such as arsenic, chromium, iodine, selenium, and others. Some of these elements are more or less inert in the plant and o...

A recent article suggests that the concept of “capital” cannot be routinely applied to the intangible items usually referred to as intellectual, social or human capital. The authors question whether ideas can be capital. We believe that this inquiry (which may reflect more general doubts) fails to capture the essential nature of capital. A reexamination of the nature of capital leads us to ask ...

Oxidation of sulfide-containing ores is the main cause of Acid Mine Drainage (AMD), which is an environmental problem associated with both the abandoned and active mines. Iron-bearing sulfide minerals can be oxidized and form mine waters with high sulfate content, low pH, high electrical conductivity, high redox potential, and high concentrations of iron, aluminum, and other heavy metals. In th...
