This study aimed to introduce a new method based on Hollow Fiber in order to determination of acetic anhydride (AA) in the air. Hydroxylamine hydrochloride and sodium hydroxide (1:1), were used as extraction solvent. This method was studied in the laboratory under various conditions. In order to make different concentrations of AA in the air, a standard glass chamber was used. The optimization ...

Tomato leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) is one of the most destructive pests of tomato in many parts of the world including Iran. The toxicity of emamectin benzoate alone and combined with acetamiprid, eforia (thiamethoxam + lambda-cyhalotrin) and hexaflumuron was evaluated against 2nd instar larvae of Tuta absoluta (Meyrick) under 25 ± 1 °C, the relative humidity of ...

The aim of this study is introduction on microbials as an effective agent in the human body. Microbial (symbiotic microorganisms) means the general and universal ecosystem of riches, all genes and masses of micronutrients, regardless of their genera and species, are referred to in a particular section. The symbiotic microbials have a symbiotic relationship with host creatures. This means that t...

Histamine is synthesized via histidine decarboxylase (HDC) in wide types of immune cells and is involved in abundant physiologic and pathologic processes. Histamine is a mediator released during inflammatory reactions, such as food allergy. Food allergy is immunological reactions to 'fight off' specific allergens within food in susceptible individuals. The aim of this study is investigation of ...

The experiment was conducted using Randomized Complete Block Design with Row Column arrangement and three replications. Grain yield, phenological and other traits were recorded. The Residual Maximum Likelihood (REML) combined analysis of variance across locations showed very highly significant (P

The present paper deals with the effects of Ohmic dissipative Casson fluid flow over a stretching sheet in the presence of aligned magnetic field. The present phenomenon also includes the interaction of thermal radiation and velocity slip. The governing boundary layer equations are transformed into a set of ordinary differential equations using the similarity transformations. The dimensionless ...

The performance of corrugated baffles inserted in a rectangular channel heat exchanger is investigated. The fluid flows and thermal distribution are determined via numerical simulations. The working fluid has a shear thinning behavior. The influence of the baffle design is explored, we interest to the “wavy” shape. The corrugation angle of baffle (α) is changed from 0° (i.e. a straight...

In this paper, the efficient multi-step differential transform method (EMsDTM) is applied to get the accurate approximate solutions for strongly nonlinear duffing oscillator. The main improvement of EMsDTM which is to reduce the number of arithmetic operations, is thoroughly investigated and compared with the classic multi-step differential transform method (MsDTM). To illustrate the applicabil...

In the present work, the numerical solution of two-dimensional variable-order fractional cable (VOFC) equation using meshless collocation methods with thin plate spline radial basis functions is considered. In the proposed methods, we first use two schemes of order O(τ2) for the time derivatives and then meshless approach is applied to the space component. Numerical results obtained ...
