In the present work, the in-flight kaon interaction on the deuteron target at incident momentum of is investigated in the channel by a phenomenological potential model. By considering the effect of resonance in the invariant mass spectra comes fromreaction, and a comparison between theoretical spectra and Braun’ s data, we found the best theoretical spectrum fitted to the experimental data. The energy and width of resonance state are respectively extracted and from the fitting process.

The aim of the present work is to introduce the concept of $\lambda _{r}$-almost convergence of sequences. We define the spaces $f\left( \lambda _{r}\right) $ and $f_{0}\left( \lambda _{r}\right) $ of $ \lambda _{r}$-almost convergent and $\lambda _{r}$-almost null sequences. We investigate some inclusion relations concerning those spaces with examples and we determine the $\beta $- and $\gamma $-duals of the space $f\left( \lambda _{r}\right) $. Finally, we give the characterization of some matrix classes.

The study of classical Littlewood-Paley operators has an intrinsic interest for their essential role in harmonic analysis due to their applications in PDEs and other fields. One of the Littlewood-Paley operators is g λ *  operator which its p,p  strong boundedness depends on the parameter λ . For example, Fefferman showed strong boundedness of classical g λ *  for 1max 1, 2 p .  In this work, We consider the Laplace-Bessel differential operator and correspondingly we define the relevant Littlewood-Paley operator g B,λ *  to investigate both L p,ν - boundedness of g B,λ *  for 2≤P<∞  and λ>1+ 2v n and its unboundedness for 0

Optimized structural architect of an Unmanned Lambda Wing Aerial Vehicle (ULWAV) during conceptual design has proven to be a significant challenge due to its unconventional configuration and no historical data for the structural architect. This paper aims to develop a new approach for structural design layout of new generation unconventional aircraft especially for ULWAV. The first step in this approach is to investigate the affecting parameters on structural architecture of these aircrafts then using of modal analysis to identification the behavior of these unconventional geometries for a general methodology development. The result of this modal analysis is apportion aircraft geometry to conventional substructures with already well-established defined architect. ULWAV structure architecture has been done by combining the structural architecture of sub-sections and with respect to requirements for systems installation, stealth design objective and packaging requirements. Here the CATIA software is used to optimize general architect with parametric model. To validate the results, the maximum static stress and maximum displacement of the structure were calculated using MSC / Patran software and compared with the values obtained from the optimization process. Dynamic analysis and buckling stability of structural composite shells are also controlled below. The architect methodology was applied to a case study of an ULWAV. The weight of the optimized structure has also been confirmed by typical case study researches.

Sunn pest, Eurygaster integriceps Puton is a key pest of wheat and barley fields that lead to use chemical control against the overwintered adults in wheat fields. Hence, to control this pest, two commercial insecticides, Deltamethrin EC 2. 5% and Fenitrothion EC 50%, were used relatively for a long time. In this research, the efficiencies of lambda cyhalothrin SC 5% (Hef-Lambda ® ), as a new insecticide, were compared with two mentioned insecticides against overwintered adults in wheat fields of three provinces, Isfahan, Lorestan and Kermanshah. Comparison were done in a randomized complete block design with three concentration of Hef-Lambda (200, 150 and 100 ml/ha), along with concentrations commonly used for Fenitrothion, Deltamethrin (1000 ml/ha and 300 ml/ha respectively) and control with four replications. The results showed that the efficiencies of Hef-Lambda (in two concentrations 200 and 150 ml/ha) and Fenitrothion and Deltamethrin on the 10th day after treatment were higher than 90% and there was no significant difference between them. So that average mortality for those treatments in overwintered adults were 91. 79, 97. 64, 96. 72 and 91. 75% respectively. In contrast, Hef-Lambda 100 ml /ha, with the 74. 07% efficiency, was in the next group. According to the results, Hef-Lambda has a good efficiency against this pest in field conditions and can be used as an alternative insecticide compare with the two mentioned insecticides, in order to reduce the possibility of resistance in Sun pest against insecticides. As the final result recommended concentration of Hef-Lambda for control of Sun pest is 150 ml/ha, in order to getting an acceptable efficiency and a low risk of contamination for environment.

In the present study, a new type of an encapsulate pesticide was prepared by Coacervation method. Lambda-Cyhalothrin was encapsulated due to interaction between two oppositely charged materials, gelatin and gum Arabic as shell in a complex Coacevation process at the presence of 10 mol etoxylated nonyl phenol (NPE) which is a kind of a non-ionic emulsifier to enhance the homogenization of the product and size control. Spherical shape of capsules were scanned by Scanning Electron Microscopy (SEM) and optical microscope. The encapsulation efficiency was achieved 96% and analyzed by Gas chromatography equipped with FID detector (GC-FID). From the results of release study, 49, 63, 89% of encapsulated materials were released from their shell after 15, 30, 180 min respectively. The present study, applies a convenient and inexpensive method to introduce a pesticide, which can be exploited in public health field.

In this paper, we aim to  state well-known Ostrowski inequality via fractional Montgomery identity for the class of $\phi-\lambda-$ convex functions. This generalized class of convex function contains other well-known convex functions from literature, allowing us to derive Ostrowski-type inequalities as specific instances. Moreover, we present Ostrowski-type inequalities for which certain powers of absolute derivatives are $\phi-\lambda-$ convex using various techniques, including Hölder's inequality and the power mean inequality. Consequently, various established results would be captured as special cases. Moreover, we provide applications in terms of special means, allowing us to derive many numerical inequalities related to special means from Ostrowski-type inequalities.
