Optimization of Gating System and Risering System for Casting of Valve Body using ADSTEFAN Simulation Software

More than 90% of all manufactured goods & capital equipment use casting for their manufacture. In spite of conventional knowledge of gating system design & suggestions by experience foundry engineers there will be a presence of various casting defects. Producing defect free casting is a challenge in manufacturing environment. Any improper designing of gating system and risering system results in various casting defects. Therefore adequate care is necessary in designing gating and risering system for impro ve yield of defect free casting. This paper aims to reduce/eliminate the casting defects in valve body by design optimizat ion of gating and rise ring system by replacing existing trial and error casting method with the help of CAD modeling and simulation software. In this paper modeling of valve body was done in NX V9 (UG) and ADSTEFAN used as simulation software.

Design of hardened by design charge pump PLL

The PLL is a feedback system used to generate clock signal in microprocessors, and frequency multiplication (FM) etc., The PLL consists of several components such as Phase frequency detector (PFD), Charge pump (CP), low pass filter (LPF), voltage controlled oscillator (VCO) and frequency divider (FD) circuits. The struck at single-event-effects (SEEs) such as latch-up, single-event-transient and multiple bit upsets which affect the PLL performance. PFD and FD which are free from dead zone due to there digital characteristics but the CP are affected by SEEs which causes the CP output to be degraded and which affect the VCO input hence PLL will lose lock. The PLL and its components are implemented in cadence virtuoso tool using 180nm technology.
TPM as a Middleware for Enterprise Data Security

— Cloud Computing is one of the emerging technologies in Computer Science. Cloud provides various types of services to us. In the Private Cloud Computing the major concern is to securing data/files and also providing privacy. Storage as a Service is generally seen as a good alternative for a small or mid-sized business that lacks the capital budget and/or technical personnel to implement and maintain their own storage. Currently, the service providers that provides cloud storage, like Dropbox provides security by server-side data encryption. Since all the encryption keys are managed by software, so such method is not secure enough. But the main issue is to maintain CIA (Confidentiality, Integrity and Authentication) to the data stored in the cloud. To achieve these we use Public Key Cryptography. For securing data we use Asymmetric key Encryption Technique. Key rings are provided by the TPM. We describe an architecture which protects enterprise data in cloud and also having authentication based on the signature. We use asymmetric keys for encrypting data. We will use the keys generated by Trusted Platform Module (TPM) for providing better security. Use of TPM is a more secure way to encrypt and decrypt data. So we have implemented a TPM as a middleware which applies the specification of Trusted Computing Group (TCG). TCG is a global industry standard, supportive of a hardware-based root of trust, for interoperable trusted computing platforms. We use TPM to encrypt data before storing it to the cloud. And we use have to use any basic Authentication Service to avoid masquerading, replay attack and eavesdropping to the client side.
Hypothyroidism and Thyroid Antibodies in Egyptian Patients with Rheumatoid Arthritis and it’s Relation to Disease Activity

Introduction: Autoimmune thyroid disease (AITD) is the most common organ specific autoimmune condition, affecting approximately 2% of the female population and 0.2 % of the male population. Thyroid dysfunction and autoantibodies have been frequently associated with rheumatoid arthritis (RA). Objective: To determine the association between hypothyroidism, thyroid autoantibodies with rheumatoid arthritis, and to evaluate any deviation of RA course with presence of thyroid antibodies. Methods: This study included 100 subjects, 70 of them were patients with rheumatoid arthritis diagnosed according to the EULAR/ARC 2010 revised criteria and 30 healthy controls. RA patients were subjected to a full assessment of medical and rheumatological history, and examination as well as routine laboratory tests. Patients and controls underwent thyroid function testing including thyroid antibodies. Patients disease activity was determined using the Modified Disease Activity Score and their functional status was assessed using the Modified Health Assessment Questionnaire. Results: Nineteen (27.1%) RA patients were found to have thyroid dysfunction. The most common thyroid dysfunction was hypothyroidism which was found in 15 (21.4%) RA patients; followed by subclinical hypothyroidism in 3 (4.3%) patients, whereas subclinical hyperthyroidism was present in one (1.4%) patient. Whereas among the control group one (3.33%) showed clinical hypothyroidism and one (3.33%) showed subclinical hypothyroidism. As regard thyroid autoantibodies; this study demonstrated that 25 (35.7%) of RA patients were positive for anti-TPO and 16 (22.9%) were positive for anti-TG. Three patients (10%) of the control group were positive for anti-TPO and two (6.66%) were positive for anti-TG. Conclusion: Thyroid dysfunctions are common in RA patients, with hypothyroidism being the most prevalent one. TSH has shown an evident positive correlation with RA disease activity as well as clinical and laboratory disease parameters. [Gamal Ali Badr, Esam Mohammed Ghamry, Arafat A.

Twelve species of twenty-four accessions miscellaneous legumes obtained from Germplasm Unit of the International Institute of Tropical Agriculture (IITA) Ibadan were accessed for their phenotypic,genetic and phylogenetic relatedness.The accessions were planted into plots of 5 ridges of 5m long,spaced 1m apart and replicated three times at Obafemi Awolowo University Teaching and Research Farm.Diversity of the accessions was accessed through vegetative comparative morphology.Differences in the mean values between two accessions were evaluated by descriptive statistics.Principal Component Analysis(PCA) was used to identify discriminatory vegetative morphological traits and similarities among the taxa were accessed through Cluster Analysis(CA). The first three principal component ax axes explained 71% of the total variation for the vegetative character.Rachis length,internode length,stipule length and stipule width were the traits which contributed most of the variations in the legume accessions.Cluster analysis grouped the 24 accessions into 5 clusters based on vegetative morphological descriptors at 0.25 level of similarity.The study revealed intraspecific similarities and inter-specific morphological and genetic diversity among the 24 miscellaneous legume accessions.
Mid-infrared spectroscopy and chemometric tools applied to quantification of adulteration in Arabica coffee by addition of roasted barley

Attenuated Total Reflectance-Fourier Transform Mid Infrared Spectroscopy (ATR-FTMIR), combined with chemometric methods, has been used to quantify the roasted barley content in a binary mixture with Arabica coffee samples, as a means for controlling and avoiding coffee adulteration, which is a very important issue taking into account the great variability of the final sale price depending on coffee varietal origin. Blends of Arabica coffee with different percentages of roasted barley were measured using ATR-FTIR spectroscopy. Spectral and reference data were firstly analyzed by principal component analysis (PCA). Partial least square regression (PLSR) was used to establish calibration model. Excellent correlation between ATR-FTIR analysis and studied coffee blends was obtained R = 0.99; with Root Mean Square Errors of Prediction < 0.34, Limit of Detection 1.012%, and Relative Prediction Errors as low as 2.054. This result demonstrated the feasibility of ATR-FTIR spectroscopy combined with chemometrics to quantify successfully binary mixtures of Arabica coffee in the 0–45 % weight ratio range of roasted barley with a reliable, rapid and inexpensive tool without the need for sample preparation. IndexTerms—Adulteration, Arabica coffee, chemometrics, infrared spectroscopy
Advancement in Single Node Data Transfer Energy Protocol Using Gateways in Wireless Sensor Network

we know in wireless sensor network energy consumption is major issue to enhance the life time of WSNs. In wireless sensor network there are different types of nodes which have different and same energy levels of nodes. The heterogeneous and homogeneous shows the energy level of nodes. As we know in homogenous there are same energy levels of nodes and heterogeneous have different 2 energy level of nodes. In this paper we proposed a new data forwarding approach to be improved the lifetime of wireless sensor network using gateways. Gateways reduce the distance between the cluster head and base station in WSNs. So we know if distance decrease between the cluster head and base station it means node life time increases and WSNs lifetime also increase. This will consume less energy in long distance communication. Simulation results show the protocol offer a batter performance.

Antioxidant and Antibacterial Activities of Two Endemic Allium L . Taxa from Turkey

In this study, antioxidant and antibacterial activities of various solvent extracts (methanol, ethanol, acetone and petroleum benzine) obtained from bulbs and leaves of Allium deciduum subsp. deciduum and subsp. retrorsum were investigated. Antioxidant activity of the extracts was determined by DPPH radical scavenging and β-carotene/linoleic acid assays. In addition, total phenolic contents in all the extracts were determined as gallic acid equivalents (GAEs). A.deciduum subsp. deciduum methanol bulbs extract showed the highest phenolic content (68.36 mg/g GAEs.). Bulbs extracts of two endemic taxa exhibited higher antioxidant activity than leaf extracts with all the types of solvent used. A positive correlation was observed between antioxidant activity and amount of phenolic contents of the extracts. Antibacterial activity of methanol and ethanol extracts was examined against two bacteria Staphylococcus aureus and Eschericha coli by agar well diffusion method and bulb methanolic extracts of A.deciduum subsp. deciduum showed more antibacterial activity against S. aureus than E.coli. Keywords— Allium deciduum, antibacterial activity, DPPH, βcaroten-linoleic acid assay.
PERFORMANCE EVALUATION OF MULTIPATH ROUTING PROTOCOL IN MOBILE AD-HOC NETWORK

— A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any existing infrastructure. Due to the dynamic nature of the network topology congestion and load balancing are the major problem in Mobile Ad-hoc Networks routing. Most of the existing protocols provide solutions to load balancing or congestion or fault tolerance individually. In this paper a load balancing algorithms (Balanced Multipath Source Routing) is implemented and analyzed. BMSR protocol distributes the traffic load over multipath route according to its minimum weight. The BMSR is implemented in NS2 and evaluate the performance based on metrics like throughput packet delivery ratio delay. The performance are measured and compared with existing DSR protocol. In this paper, the simulation results show that the BMSR algorithm solves the problem of congestion through load balancing in different scenarios through which BMSR outperforms DSR significantly.
Fungal cardiomyopathy: A review and pooled analysis of pathophysiology, diagnosis and clinical management

The incidence of invasive fungal disease has dramatically increased over the past few decades corresponding to the rising number of immunocompromised patients – mostly those with Human Immunodeficiency Virus (HIV)/Acquired Immunodeficiency syndrome (AIDS) and cancer. The major risk factors for severe cardiac fungal disease are prolonged administration of antibiotics, corticosteroids and cytotoxic agents, invasive medical procedures, and transplant recipients. Invasive fungal infection often affects multiple organs and cardiac involvement frequently occurs in disseminated disease. Ante mortem diagnosis of fungal cardiomyopathy (FCM) is difficult because clinical findings of myocardial involvement are often absent or ambiguous and blood cultures are often negative. Although an uncommon cause of infectious cardiomyopathy (CM), FCM is potentially fatal and thus early diagnosis of the primary infecting fungal pathogen, organs involved and the status of the host immune system is important to guide clinical management. Thus, this paper reviews the major fungal pathogens responsible for CM, clinical setting in which they occur, pathophysiology, diagnosis and management as well as highlights the burden of cardiac fungal infection and the need for additional research to refine current strategies or develop more effective diagnostic and therapeutic strategies. *Correspondence to: Aref Albakri, St-Marien hospital Bonn Venusberg, Department of Internal Medicine, Bonn, Germany, E-mail: arefalbakri@yahoo. com
A REVIEW OF DISTRIBUTED QUERY SYSTEMS IN CLOUD COMPUTING

: The size of the databases has grown beyond what can be managed efficiently by a single server. So, data distribution is the only viable option concerning performance and efficiency. Scalability is an important factors needed especially in distributed environment like grid or cloud computing. These paradigms expect almost infinite scalability which means at least thousands of sites. So we need systems which not only provide scalability but its automatic adaption as well, as scalability increases or decreases. This review paper presents the querying systems used to provide scalability, aggregation and fault tolerance.
Understanding Nursing Activities with Long-term Mobile Activity Recognition with Big Dataset

In this paper, we introduce a real nursing sensor dataset which includes labeled dataset for supervised machine learning and the big data combined with patient medical records and sensors attempted for 2 years, and also describe a method for recognizing activities for a whole day utilizing prior knowledge about the activity segments in a day and utilizing importance sampling and Bayesian estimation, based on our paper at UbiComp2015 [13]. Moreover, we demonstrate data mining by applying our method to the bigger data with additional hospital data. Our method of recognizing a whole day activities outperformed the traditional method without using the prior knowledge. Moreover, the method signiﬁcantly reduces the duration errors of activity segments. We also demonstrate a data mining applying our method to bigger data in a hospital, and show several results about the correlations with nurse proﬁles and patients status using Random Forest regression.
Induction of Oxidative Stress and Osmolyte Accumulation In Response to Sodium Arsenate Toxicity in Mungbean Seedlings and Its Amelioration

Effect of sodium arsenate (Na2HAsO4.7H2O) on the growth and activity of few oxidizing enzymes of mungbean seedlings was investigated and it was found to have drastic effects on the growth and biochemical metabolism of germinating mungbean (Vigna radiata (L.) Wilczek cv. B-105) seedlings. With the increase in concentration of sodium arsenate (5μM, 10μM and 20μM) significant decrease in seedling length and fresh weight and dry weight of mungbean seedlings was observed. Different growth promoters were used for amelioration. Reduction in growth inhibition was achieved by pretreating the seeds with phytohormones (GA3, IAA, Kinetin), macronutrients (KH2PO4, NaH2PO4.2H2O, K2SO4, CaCl2.2H2O, MgSO4.7H2O); best results were shown by GA3, KH2PO4, NaH2PO4 and pyruvate. Under arsenate induced oxidative stress levels of proline, H2O2 and phenol content was found to be elevated. An appreciable stimulation in the activity of some antioxidant enzymes, viz., catalase, catechol peroxidase, ascorbate peroxidase, polyphenol oxidase and ascorbic acid oxidase was noticed in seedlings growing in presence of sodium arsenate indicating oxidative stress. Pretreatment of mungbean seedlings with GA3, KH2PO4, and NaH2PO4.2H2O helped in reduction of oxidative stress (to some extent) as observed by increased seedling growth and lower activities of antioxidant enzymes and lesser accumulation of osmolyte Proline. It is assumed that pretreatment with GA3, KH2PO4, and NaH2PO4.2H2O provided resistance to the mungbean seedlings against As-toxicity and hence has an ameliorating effect against As-induced stress.
Review on Different Sources for the Production of Biodiesel

Biodiesel is generally produced from various seed oils such as soybeans, rapeseed and corn. Such a diesel can be used in cars, trucks, busses, construction equipment, in jet engines and in heating and electricity generating systems, but only through blends with maximum blend up to 25% (v/v) Biofuels burn cleaner than fossil fuels. They don't produce sulphur or aromatics. Main benefit of using biodiesel is that, it reduces nitrogen oxide emissions compared to fossil fuel. This article reviews different sources for the production of biodiesel. Biodiesel is environmentally safer than petro-diesel. It is nontoxic, produces less skin irritation, it degrades four times as fast as petro-diesel, has a flash point significantly higher than that of petro diesel, thus making it safer to store and handle.

When visitors use outbound tours, tour guides will become an important bridge between service providers and tourists, tourist and destination. This research was constructed to investigate the impacts of tour guide‟s performance on tourist‟s trusts, their satisfaction through that affect the word of mouth intention of them. By collecting data from 203 respondents who used to travel by outbound tour in Ho Chi Minh City and using Smart-PLS software to testing the proposed model, the study‟s results confirmed that tour guide‟s performance has significant influence on tourist‟s satisfaction and their perceived trusts (benevolence trust and credibility trust) and then impacts positively on tourist word of mouth intention. Therefore, this study can provide some recommendation for tour agents and their managers to improve tour guide‟s performance for achieving tourist‟s satisfaction.
Anti-oxidized LDL antibodies as atherosclerosis development markers in HIV patients undergoing antiretroviral therapy : a longitudinal cohort study

Antiretroviral therapy (ART) drastically improved the life expectancy and quality of Human Immunodeficiency Virus (HIV)-infected patients, but ART causes adverse effects that include metabolic alterations considered risk factors for atherosclerosis that need monitoring. Anti-oxidized LDL (oxLDL) antibodies with known role in atherosclerosis may be used as a marker to monitor its development. A longitudinal cohort study for 12 months involved Naïve patients (n=20) with no ART, and ART patients (n=51) that initiated ART during the study period. CD4 T cell counts, viral load, lipid profile, antioxLDL and anti-apolipoprotein B-derived peptide D antibodies and carotid intima-media thickness (IMT) were evaluated. The ART group significantly recovered the CD4 T cell count (P<0.001) and lowered the viral load (P<0.001) while the Naïve group maintained their levels throughout. Anti-oxLDL and antiapoB-D antibody levels were correlated (r=0.657, P<0.001), and were similar between groups at time zero. They progressively decreased in the ART group in the 12-month period but there was no change in the Naïve group. At 12 months, a carotid IMT was evaluated in 18 patients undergoing ART, and it was found above or close to the upper normal value in all. We found an inverse correlation between carotid IMT and anti-apoB-D (r=-0.410, P=0.045) and anti-oxLDL (r=-0.392, P=0.054) antibody levels. Antiretroviral therapy improved the parameters of HIV infection, but it may have induced increased carotid IMT. Its inverse correlation mainly with anti-apoB-D antibody level strengthens this antibody level trend as a marker of atherosclerosis development in HIV patients under antiretroviral therapy.
