Abstract: A Gram-positive, yellowish bacterium strain AK-1T was isolated from soil sample collected from peanut (Arachis hypogaea) crop field and studied by using a polyphasic approach. The organism had morphological and chemotaxonomic properties consistent with its classification in the genus Agromyces. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain AK-1T was closely related to Agromyces aurantiacus (98.6%) followed by Agromyces soli (98.3%), Agromyces tropicus (97.6%), Agromyces ulmi (97.3%), Agromyces flavus (97.2%), and Agromyces italicus (97.0%), whereas the sequence similarity values with respect to the other Agromyces species with validly published names were between 95.3 and 96.7?%. However, the DNA-DNA hybridization values obtained between strain AK-1T and other related strains were well below the threshold that is required for the proposal of a novel species. The DNA content of the strain is 71.8?mol%. The above data in combination with the phenotypic distinctiveness of AK-1T clearly indicate that the strain represents a novel species, for which the name Agromyces arachidis sp. nov. is proposed. The type strain is AK-1T (=MTCC 10524T = JCM 19251T). 1. Introduction The genus Agromyces was first proposed by Gledhill and Casida Jr [1] and later on emended by Zgurskaya et al. [2]. At present, the genus Agromyces comprises ??24 species with validly published names (http://www.bacterio.net/a/agromyces.html), and all these species have been isolated from different environmental sources: soils from fertile meadows, rhizosphere, and plants to rock art paintings [1–18]. In the present study, bacterial strain AK-1T, isolated from soil sample, is described and subjected to the polyphasic taxonomy. 16S rRNA gene sequence comparison revealed that the isolate is Agromyces-like organism. The aim of the present study is to determine the exact taxonomic position of the isolate. 2. Materials and Methods Strain AK-1T was isolated from a soil sample collected from peanut (Arachis hypogaea) crop field, Srikakulam, Andhra Pradesh, India (18°14′N latitude 83°58′E longitude), by the dilution-plate technique on tryptic soy agar medium (TSA; HiMedia) and maintained as glycerol stocks at ?70?°C. The reference strains A. aurantiacus (MTCC 11069T), A. soli (MTCC 11074T), A. tropicus (MTCC 11075T), A. ulmi (MTCC 10783T), A. flavus (MTCC 11103T), and A. italicus (MTCC 10784T) were obtained from the Microbial Type Culture Collection and Gene Bank (MTCC), Institute of Microbial Technology, Chandigarh, India. Colony and cell morphologies were studied according to

Abstract: A wireless network is not as secure as compare the wired network because the data is transferred on air so any intruder can use hacking techniques to access that data. Indeed it is difficult to protect the data and provide the user a secure information system for lifetime. An intrusions detection system aim to detect the different attacks against network and system. An intrusion detection system should be capable for detecting the misuse of the network whether it will be by the authenticated user or by an attacker. Cross layer based technique help to make decision based on two layer physical layer where we compute RSS value and on MAC layer where one compute RTS-CTS time taken. This will reduce the positive false rate.They detect attempts and active misuse either by legitimate users of the information systems or by external. The paper has higlighted the advances in intrusion detection in wireless local area network.

Abstract: Spontaneous rupture of abdominal aortic aneurysm into the inferior vena cava is rare and is associated with high mortality and morbidity. The clinical presentation can be variable and thus the diagnosis can be difficult. It can present with symptoms and signs of an abdominal emergency, venous hypertension, or systemic hypoperfusion. The traditional method of repair has been open surgery which is associated with high rate of complications. We report a case of aortocaval fistula (ACF) presenting with acute renal failure and heart failure, which was treated successfully with a novel, endovascular approach. 1. Case Presentation A 63-year-old Caucasian male with no known past medical history, presented with shortness of breath, productive cough, orthopnea, paroxysmal nocturnal dyspnea, and lower extremity edema of one month’s duration. Patient also reported an associated weight gain of 7 pounds and occasional flank pain. Prior to admission, he had received treatment with azithromycin and levofloxacin for presumed community acquired pneumonia without improvement. Patient denied a history of smoking. On admission, the vital signs were as follows: blood pressure 127/61, heart rate 101?beats/min, and regular, respiratory rate 18/min and oxygen saturation 98% on 2?liters/min of supplemental oxygen. Patient exhibited basilar pulmonary rales, a gallop rhythm, peripheral edema and elevated jugular venous pressure, suggestive of acute decompensated heart failure. Additionally, a loud abdominal bruit was heard and no abdominal masses were palpable. Pertinent laboratory data on admission included a creatinine of 1.6?mg/dL and hemoglobin of 11.6?g/dL. Urinalysis did not reveal hematuria or pyuria. He was started on medical management for acute decompensated heart failure. A transthoracic echocardiogram was performed which showed normal left ventricular systolic function, elevated right ventricular systolic pressure ( ?mmHg) along with right ventricular hypertrophy. A diagnostic left and right heart catheterization was performed which showed 80% stenosis of the left anterior descending artery, needing angioplasty. In addition, there were findings of severe pulmonary hypertension, high cardiac output, and a stepup in oxygen saturation in the inferior vena cava (IVC) compared to that of superior vena cava (SVC). These findings are summarized in Tables 1 and 2. Subsequently, the patient developed hypotension necessitating transfer to intensive care unit for vasopressor support. He rapidly developed signs of visceral and peripheral hypoperfusion including acute hepatic

Abstract: The effect of water deficit on stem reserve mobilization and sink activity in wheat (Triticum aestivum L.) cultivars, viz., C306 (drought tolerant) and PBW343 (drought sensitive) was studied. Drought was maintained in pot raised plants by withholding irrigation at 95 days after sowing (DAS), i.e. just five days before the initiation of anthesis. Drought induced a significant reduction in mean biomass of all the internodes of sensitive cultivar as compared to those of tolerant one. Mobilized dry matter and mobilization efficiency were observed to be higher in the internodes of tolerant cultivar, both under control and stress conditions, which resulted in enhanced translocation of stem reserves to the grains. Water soluble carbohydrates (WSC), which mainly occur as fructans, were observed to be higher in the internodes of tolerant cultivar than those of sensitive one. When drought was applied, fructans were mobilized more effectively from the internodes of tolerant cultivar. A significantly higher sucrose synthase activity in the grains of tolerant cultivar, under drought conditions, increased the sink strength by unloading the assimilates in the sink, thereby increasing further mobilization of assimilates to the grains. Grains of sensitive cultivar attained maturity much earlier as compared to the tolerant one, both under control and stress conditions. The longer duration of grain maturation in tolerant cultivar supported enhanced mobilization of stem reserves, thus restricting heavy decrease in grain yield, under stress conditions, as compared to the sensitive cultivar. It may, therefore, be concluded that certain characteristics viz., enhanced capability of fructan storage, higher mobilization efficiency, stronger sink activity and longer duration of grain maturation might help the drought tolerant cultivar in coping the stress conditions

Abstract: Age related changes in body composition are associated with long term dietary intake profiles. Age related increase in body fat is primarily attributed to decline in physical activity and basal metabolic rate as well as dietary intake. The study was designed to assess the body composition, dietary intake and physical activity level of sedentary adult women of different age groups. A cross-sectional study was conducted on 152 sedentary adult women comprised of students and faculty from Punjab Agricultural University, Ludhiana. The relationship of body composition with dietary factors and physical activity level of women in four age groups i.e. 21 - 30, 31 - 40, 41 - 50 and 51 - 60 years was determined. A gradual increase (p ≤ 0.05) in anthropometric and body composition parameters such as weight, waist circumference, hip circumference, body mass index, fat mass and visceral fat rating was observed with the advancement of age. The lean body mass was decreased significantly (p ≤ 0.05) as the age progressed, the values for four age groups being 74.9, 68.9, 62.8 and 60.9%, respectively. Contrary to this fat mass increased with age, the corresponding values for four age groups being 15.7, 21.4, 26.6 and 29.2 kg, respectively. The percent adequacy of protein by four age groups was 69.6, 78.2, 80.0 and 66.3, respectively when compared to RDA while fat intake was much higher i.e. 245.5, 271.8, 288.4 and 250.8%, respectively. The energy intake was inadequate among all age groups, however, a significant (p ≤ 0.05) differ- ence was observed in daily energy consumption between the age groups. The mean physical activity level (PAL) of the subjects ranged between 1.49 - 1.60. The physical activity level values showed that majority of the subjects (87% - 94%) were having sedentary life style. Age is a crucial factor associated with body composition. A high fat mass and low lean body mass of the subjects was observed. Their diets were low in protein but high in fat. Majority of the subjects from different age groups had sedentary life style. A diet with higher protein and lesser fat combined with exercise can help in sustaining optimum body composition.

Abstract: The isolation of high quality RNA is a crucial technique in plant molecular biology. The quality of RNA determines the reliability of downstream process like real time PCR. In this paper, we reported a high quality RNA extraction protocol for a variety of plant species. Our protocol is time effective than traditional RNA extraction methods. The method takes only an hour to complete the procedure. Spectral measurement and electrophoresis were used to demonstrate RNA quality and quantity. The extracted RNA was further used for cDNA synthesis, expression analysis and copy number determination through Real Time PCR. The results indicate that RNA was of good quality and fit for real time PCR. This high throughput plant RNA extraction protocol can be used to isolate high quality RNA from diverse plants for real time PCR and other downstream applications.
A New Approach to Software Development Fusion Process Model  [PDF]
Rupinder Kaur, Jyotsna Sengupta
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.310117
Abstract: There are several software process models that have been proposed and are based on task involved in developing and maintaining software product. The large number of software projects not meeting their expectation in terms of functionality, cost, delivery schedule and effective project management appears to be lacking. In this paper, we present a new software fusion process model, which depicts the essential phases of a software project from initiate stage until the product is retired. Fusion is component based software process model, where each component implements a problem solving model. This approach reduces the risk associated with cost and time, as these risks will be limited to a component only and ensure the overall quality of software system by considering the changing requirements of customer, risk assessment, identification, evaluation and composition of relative concerns at each phase of development process.
