Different nitrogen

By analyzing some soil chemical properties such as: SOC content, macronutrients, ion mobilized Fe, this paper will focus on: (1) description of soil chemical properties at different soil horizons under two forest types; (2) analyzing differences of those soil properties and (3) analyzing the correlation between investigated soil parameters in Kon Ka Kinh National Park, Central Highlands, Vietnam.

Ebook "Halogenated heterocycles: Synthesis, application and environment" structures contain at least two different atoms as members of a saturated, unsaturated or aromatic ring, which forms either a simple monocyclic compound or a part of a larger structure of fused rings. Equally, halogenation is a similarly broad field and both topics are interwoven within these chapters.

In the present study, the effects of different dietary protein levels on salema porgy, Sarpa salpa (Linnaeus, 1758) juveniles were investigated. As a result, S. salpa demonstrated better growth with low protein diets, showing that this marine fish could be a promising candidate for a sustainable and environment friendly aquaculture industry.

The experiment was conducted to study the effect of different air pollution (ozone O3, sulfur dioxide SO2, and nitrogen dioxide NO2 gases) on Eruca sativa Mill. at three locations in Riyadh city, KSA. During the study, we found that the concentrations of gases were increasing gradually at the study sites.

In nitrogen treatment with biological methods, nitrite metabolism is an intermediate process that facilitates other processes involving different bacteria strains. In this study, we isolated two nitriteoxidising bacteria strains from abattoir wastewater and wastewater from biogas tanks of an industrial pig farm in Ha Tinh province.

Imidazoles and their scaffold are an extraordinarily essential class of nitrogen bearing azole heterocyclic compounds. They have different place in wide area of organic synthesis, which can be utilized in a variety of applications in diverse fields including agriculture, medicine, polymer and various industries. Numerous methods for synthesis of imidazole derivatives are reported in last few decades.

Analysis of multiple equilibria of compounds with different coordination sites is extended to the description of adsorption isotherms with focus on the low relative pressure range. The entropy evolution is described using the particle distribution theory which also holds for adsorbents consisting of materials bearing more than one type of sites and applies for the condition that the adsorptive-adsorbent binding strength is larger than the adsorptiveadsorbate binding strength, so that monolayer coverage is favored.

Genomes are composed of long strings of nucleotide monomers (A, C, G and T) that are either scavenged from the organism’s environment or built from metabolic precursors. The biosynthesis of each nucleotide differs in atomic requirements with different nucleotides requiring different quantities of nitrogen atoms.

Soil type is a vital determinant of soil fertility because of its characteristic biological, chemical, and physical properties. However, the soil fertility of upland soil is probably changed by different agricultural management practices regardless of soil type. This study investigated the features of soil fertility (bacterial biomass, total carbon (TC), and total nitrogen (TN)) in upland fields in Japan. One thousand soil samples from different soil types were collected from upland fields located on 36 prefectures in Japan.
