14C-labelled proteins from E. coli 30S ribosomal subunits were isolated by HPLC, and selected groups of these proteins were reconstituted with 32P-labelled 16S RNA. The isolated reconstituted particles were partially digested with ribonuclease A, and the RNA fragments protected by the proteins were separated by gel electrophoresis and subjected to sequence analysis. Protein S7 alone gave no pro...
The Siemens S7 protocol is commonly used in SCADA systems for communications between a Human Machine Interface (HMI) and the Programmable Logic Controllers (PLCs). This paper presents a model-based Intrusion Detection Systems (IDS) designed for S7 networks. The approach is based on the key observation that S7 traffic to and from a specific PLC is highly periodic; as a result, each HMI-PLC chann...

The massive production and improper disposal of organohalides resulted in worldwide contamination in soil and water. However, their environmental survey based on chromatographic methods was hindered by challenges in testing the extremely wide variety of organohalides. Dehalococcoides as obligate organohalide-respiring bacteria exclusively use organohalides as electron acceptors to support their...
To evaluate the efficacy of passive restoration on soil seed bank and vegetation recovery, we measured the species composition and density of the soil seed bank, as well as the species composition, density, coverage, and height of the extant vegetation in sites passively restored for 0, 4, 7, and 12 years (S0, S4, S7, and S12) in a degraded grassland in desert land. Compared with S0, three more...
The N-glycans of membrane glycoproteins are mainly exposed to the extracellular space. Human tyrosinase is a transmembrane glycoprotein with six or seven bulky N-glycans exposed towards the lumen of subcellular organelles. The central active site region of human tyrosinase is modeled here within less than 2.5 Å accuracy starting from Streptomyces castaneoglobisporus tyrosinase. The model accoun...
BACKGROUND Pediatric fixed-dose combinations (FDCs) are needed to facilitate antiretroviral therapy in children. We evaluated the relative bioavailability, safety, and therapeutic adequacy of a novel chewable pediatric FDC tablet of stavudine (7 mg), lamivudine (30 mg), and nevirapine (50 mg), referred to as GPO-VIR S7, and compared it with the individual original brand-name liquid formulations...
Secondary and tertiary structural models of sodium channel transmembrane segments were developed from its recently determined primary sequence in Electrophorus electricus. The model has four homologous domains, and each domain has eight homologous transmembrane segments, S1 through S8. Each domain contains three relatively apolar segments (S1, S2 and S3) and two very apolar segments (S5 and S8)...
پس از پیروزی انقلاب اسلامی در ایران در برخی از نهادهای جوشیده از متن انقلاب از جمله جهاد سازندگی و البته درمدیریت جنگ تحمیلی و الگوهای پیاده شده در دوران دفاع مقدس مکانیزم ها و رهیافت های جدیدی خلق شد و به مورد اجرا درآمد که با نظام سنتی سازمان ها تفاوت فاحشی داشت. بدین معنی که دیگر از آن نظام سنتی تمرکزگرا خبری نبود بلکه ساختار و نظام مدیریت مشارکتی نوینی براساس رهنمودها و برداشت هایی از نظام ...
Omnidirectional reflectivity is theoretically investigated in four Thue-Morse (T-M) structures S4, S5, S6 and S7. It is observed that the width of omnidirectional reflection region increases with the order of T-M multilayer i.e. from S4 to S7 generation and multiple photonic band gaps exist for both TE and TM modes due to self-similarity of T-M multilayers. It can also be found that multiple om...
