The synthesis, characterization and X-ray crystal structure of 2-(4-chloro-phenyl)-7-methylpyrrolo[1,2-b]pyridazine are reported. The compound crystallizes in the space group P2(1)/c (No.14) with a =3.8568(1), b = 11.0690(3), c = 26.4243(7) A, beta =92.777(1) degrees and Z = 4. Accurate molecular parameters for the novel heterocyclic system were obtained from intensity data collected at 113K. T...
Five weeks old guinea fowls were inoculated intraocularly with a 20% bursal suspension containing a local Nigerian isolate of infectious burfa! disease virus (IBDV) which had a bursal lesion titre of 10· per 0.5 mI. No clinical signs were observed. Gross lesions were absent and microscopic lesions were not found in the bursa, spleen and kidney on days 3 and 5 post infection (PI). IBDV antigen w...
General methods were developed and applied to the biosynthesis and purification of products of activated lymphocytes available in minute quantities. The activity studied here was the migration inhibitory factor (MIF) produced by purified protein derivative (PPD)- or concanavalin A (Con A)-stimulated lymphocytes obtained from one guinea pig or less. The methods selected yielded results in terms ...
OBJECTIVES Lactoferrin (LF) is an iron binding protein and stored in the specific granules of granulocytes. It is released by degranulation following granulocyte activation. A positive correlation was previously reported between periodontitis and LF titers of gingival crevicular fluid (GCF) and blood. The purpose of this study was to examine alterations of GCF and blood levels of LF (LF-GCF and...
Let G be a 2-connected graph of order n with x, y ∈ V (G). For u, v ∈ V (G), let Pi[u, v] denote the path with i vertices which connects u and v. In this paper, we prove that if n ≥ 5 and |NG(u)∪NG(v)|+dG(w) ≥ n+1 for every triple of independent vertices u, v, w of G, then there exists a Pi[x, y] in G for 5 ≤ i ≤ n, or G belongs to one of three exceptional classes. This implies a positive answe...
موضوع پایداری در میکروشبکه ها همچون سیستم های قدرت سنّتی، مولفه مهمی برای مدیریت انرژی و برنامه ریزی می باشد. پایداری ولتاژ و فرکانس از مهمترین مواردی است که اخیراً در زمینه میکروشبکه ها مطالعه شده است. هدف از انجام این پایان نامه، طراحی و مدلسازی عناصر و کنترلرها و ارائه روش های جدیدی برای کنترل ولتاژ در یک میکروشبکه هیبرید ac/dc و در شرایط وقوع اغتشاشات مختلف می باشد. همچنین توانایی این روش ها ...
Eight-week-old BALB/c mice were either sham inoculated (control mice) or were inoculated intraperitoneally (IP) and intranasally (IN) with a single (sPCV mice) or multiple (mPCV mice) doses of porcine circovirus 2 (PCV2). Four control mice and 4 sPCV mice were sacrificed 7, 14, 28, and 42 days postinoculation (PI). All 4 mPCV mice were sacrificed 42 days PI. In addition, 7-day and 14-day pregna...
The present study was designed to assess the dynamic patterns of pro-inflammatory cytokines, including IFN-γ, TNF-α, IL-4, IL-6, acute phase protein (α1-acid-glycoprotein, AGP), and an inflammation associated factor (adenosine deaminase; ADA) following experimental caprine coccidiosis. Ten kids aging from 2 to 4 months were infected orally with 5×104 sporulated oocysts and 10 animals served as ...
Using psi(2S)-->pi;{+}pi;{-}J/psi, J/psi-->gammaeta;{'} events acquired with the CLEO-c detector at the CESR e;{+}e;{-} collider, we make the first observations of the decays eta;{'}-->pi;{+}pi;{-}pi;{0} and eta;{'}-->pi;{+}pi;{-}e;{+}e;{-}, measuring absolute branching fractions (37_{-9};{+11}+/-4)x10;{-4} and (25_{-9};{+12}+/-5)x10;{-4}, respectively. For eta;{'}-->pi;{+}pi;{-}pi;{0}, this re...
The most precise value for the pion mass was determined from a precision measurement at PSI of muon momentum in decay rest, \pi^+ \rightarrow \mu^+ + \nu_{\mu} π+→μ++<mm...
