ABSTRACT We embed linear and non-linear parametrizations of beyond standard cosmological physics in the halo model reaction framework, providing a model-independent prescription for matter power spectrum. As an application, we focus on Horndeski theories, using Effective Field Theory Dark Energy (EFTofDE) to parametrize quasi-non-linear perturbations. In regime, investigate both parametrized po...
This contribution presents a derivation of the steady-state distribution of velocities and distances of driven particles on a onedimensional periodic ring. We will compare two different situations: (i) symmetrical interaction forces fulfilling Newton’s law of “actio = reactio” and (ii) asymmetric, forwardly directed interactions as, for example in vehicular traffic. Surprisingly, the steady-sta...
به منظور شناسایی و ارزیابی لاینهای بومی عدس زراعی استان آذربایجان غربی و همچنین بررسی شاخصهای تحمل به خشکی در گیاه عدس، در سال 1379 تعداد 51 لاین از نقاط مختلف اکولوژیکی استان جمع آوری گردیده است. این لاینها در سال بعد بصورت طرح مقدماتی (در قالب طرح بلوک های کامل تصادفی ) به همراه 6 شاهد در دو شرایط دیم و آبی در ایستگاه تحقیقات کشاورزی دکتر نخجوانی ارومیه مورد ارزیابی قرار گرفته است.نتایج نشان ...
Scanning Electro n Mic roscopy (SEM) and X· ray Mic ro· analys is (EOS) have been used to investigate product conwinc r interaction problems in plai n tinplate metal food containers and to examine glass and glass-like particles that we re found in canned food . Through the usc o f SEMEDS. it wa~ detemlined that: sulfa te contain ing panicles from the cannery cooling water reacted with exposed i...
The fi rst az.ide-contain ing sugar, a glycosyl azide. was reponed in 1930 by Bertho. j Since that lime various methods have been developed for the introduction of azides at d ifferent positions of sugars. A survey of available methods is given in Section 16.2. Unlillhc lale I 970s, azidcs contai ned in carbohydrate deri vatives were simply used as accessible syn-thons [or amities because of th...
زمینه و هدف: استافیلوکوکوس اورئوس، کوکسی گرم مثبتی است که در شرایط خاص توانایی ایجاد بیماری های مختلف را دارد. این باکتری با ترشح سموم مختلف از جمله انتروتوکسین شرایط تهاجم به میزبان را فراهم می آورد. در میان این سموم، انتروتوکسین a و b بیشترین نقش را در بیماری زایی ایفا می کنند. این تحقیق جهت ردیابی ژن های انتروتوکسین a و b در نمونه های بالینی صورت گرفته است. مواد و روش ها: این مطالعه توصیفی...
Mechanisms for detecting neutrons in matter are based on indirect methods. Neutrons, as their name suggests, are neutral. Also, they do not interact directly with the electrons in matter, as gamma ray$ do. The process of neutron detection begins when neutrons, interacting with various nuclei, initiate the release of one or more charged particles. The electrical signrdsproduced by the charged pa...
1. The proportion of active (dephosphorylated) pyruvate dehydrogenase in perfused rat heart was decreased by alloxan-diabetes or by perfusion with media containing acetate, n-octanoate or palmitate. The total activity, of the dehydrogenase was unchanged. 2. Pyruvate (5 or 25mm) or dichloroacetate (1m) increased the proption of active (dephosphorylated) pyruvate debydrogenase in perfused rat hea...

We investigate an atomic three-level Λ-system which is exposed to two counterpropagating laser fields (inducing Raman transitions) and which is closed by a magnetic hyperfine field tuned to be in resonance with the transition between the two ground states. The influence of a homogeneous gravitational field is included in a full quantum treatment of the internal and external dynamics of the atom...
