A New Chaos Based Image Encryption and Decryption Using a Hash Function

- Chaos-based image encryption/decryption techniques have recently been extensively studied due to their superior properties in efficiency and speed. However, many of the proposed schemes suffer from known plain-text attacks. This paper suggests a new, fast chaos-based image encryption and decryption with a plain-text related permutation. Permutation and diffusion is used for encryption process. To shuffle the position of image pixels and generate the diffusion key stream the Arnold’s cat-map and Lorenz system is used, respectively. A hash function is used to generate permutation/diffusion key, in this murmur3 hash algorithm is employed to generate hash value. Hash functions are having the unique property that it will produce completely different shuffled images even if there is a tiny difference between images and it helps accelerate the diffusion process. As a result, the proposed scheme reduces the number of cipher cycles to achieve acceptable and good diffusion properties.

Abstract: The Orang Asli community is among the indigenous people of Peninsular Malaysia who majority of them

1541 Published By: Blue Eyes Intelligence Engineering & Sciences Publication Retrieval Number:F12730476S519/19©BEIESP Abstract: The Orang Asli community is among the indigenous people of Peninsular Malaysia who majority of them reside in the remote areas and is still behind the flow of national development. Although various development programs have been implemented, the community's well-being level is still low compared to other communities in Malaysia. Based on this issue, two objectives have been developed in this study; to identify the level and factors of the Orang Asli community’s participation in social development programs. This study was conducted in two Orang Asli villages namely Kampung Sungai Pergam, Kemaman and Kampung Sungai Berua, Hulu Terengganu by using qualitative method. Data was collected using participating observation techniques and interviews. The findings show that the status of Orang Asli’s participation in social development programs is at a low level as most of them are only participating in programs implemented on certain factors. This is because the cultural and environmental factors of this community have influenced the status of their participation in the social development program implemented. These factors are attitudes or behaviours, norms, family factors, cognitive factors, nutritional factors and technological factors. The results of this study can benefit the management of the agency in the implementation of development programs that can improve the status of the livelihood of the Orang Asli community in Terengganu. The important thing to be aware of in order to enhance the effectiveness of the programs and the participation of the Orang Asli communities in development programs is to get members of the Orang Asli involved at the planning stage to ensure that programs are being implemented according to the needs of the community[7].
Non-testosterone management of male hypogonadism: an examination of the existing literature

Testosterone deficiency is defined as a total testosterone level <300 ng/dL confirmed on two early morning lab draws. Testosterone therapy has historically been offered to men with symptomatic testosterone deficiency in the form of injections, gels, or pellets. However, these treatments are invasive or have undesirable effects including the risk of drug transference. Additionally, testosterone therapy has been associated with increases in hematocrit and controversy remains regarding the risk of cardiovascular and thromboembolic events while on testosterone therapy. As such, much interest has recently been focused on alternative treatment options for testosterone deficiency in the form of orally-administered medications with more favorable side effect profiles. Lifestyle modifications and varicocelectomy have been shown to raise endogenous testosterone production. Similarly, SERMs and aromatase inhibitors (AIs) have been shown to raise testosterone levels safely and effectively. Human chorionic gonadotropin (hCG) remains the only FDA-approved non-testosterone treatment option for testosterone deficiency in men. However, this medication is expensive and requires patient-administered injections. Over the counter herbal supplements and designer steroids remain available though they are poorly studied and are associated with the potential for abuse as well as increased hepatic and cardiovascular risks. This review aims to discuss the existing treatment alternatives to traditional testosterone therapy, including efficacy, safety, and side effects of these options. The authors suggest that the SERM clomiphene citrate (CC) holds the greatest promise as a non-testosterone treatment option for testosterone deficiency.
IDENTIFYING THE SELECTED IMAGE FROM MULTI LAYERED PATCHES USING IMAGE PROCESSING

— We propose an image processing model recognize image in multi layered patches. We extract all patches with overlaps, refer to these as coordinates in high-dimensional space, and order them. The generative models can be learned one layer at a time and when learning is complete they have a very fast inference procedure for computing a good approximation to the posterior distribution in all of the hidden layers This enables us to obtain good identity of the selected image by applying relatively simple identifier (1D) operations to the reordered set of pixels. We explore the use of the proposed approach to image denoising and inpainting, and show promising results of natural images.
Extension communication channels’ usage and preference by farmers in Benue State, Nigeria

The study assessed farmers’ use and preference of extension communication channels in Benue State, Nigeria. A sample of 316 farmers was selected through a stratified random sampling technique and interview schedule was used in eliciting information from them. Descriptive and inferential statistics were used for data analyses. Interpersonal communication channels were generally found to be more available, accessible and used by the farmers than the mass media to obtain information on improved farm technologies. Relatives/friends/neighbours constituted the most regularly available, accessible and used interpersonal channels although extension agents and television were mentioned by the farmers as the most preferred interpersonal channel and mass medium, respectively. Chi-square analysis shows that there is significant relationship between frequency of communication channels use by farmers and their educational level, sex, farm size and farming experience. It is recommended that rural radio booster stations and community rural television stations are established to feature special programmes targeted at rural farmers. To ensure regular availability and accessibility of extension agents (the farmers most preferred channel), efforts should be made to employ more extension agents.

We conclude this is, to the best of our knowledge, the first case repot of necrotizing pneumonia due to C. indologenes, a rare disease agent with low pathogenicity but capable of causing severe illness especially in immunocompromised patients.
Implementation of SAODV and TAODV Adhoc Secure Routing Protocols

— Mobile Ad-hoc Networks (MANETs) allow wireless nodes to form a network without requiring a fixed infrastructure. Early routing protocols for MANETs failed to take security issues into account. Subsequent proposals used strong cryptographic methods to secure the routing information. In the process, however, these protocols created new avenues for denial of service (DoS). Consequently, the trade-off between security strength and DoS vulnerability has emerged as an area requiring further investigation. It is believed that different trust methods can be used to develop protocols at various levels in this trade-off. To gain a handle on this exchange, real world testing that evaluates the cost of existing proposals is necessary. Without this, future protocol design is mere speculation. In this paper, we give the first comparison of SAODV and TAODV, two MANET routing protocols, which address routing security through cryptographic and trust-based means respectively. We provide performance comparisons on actual resource-limited hardware. Finally, we discuss design decisions for future routing protocols.
Evaluation of the influence of smear layer removal on the apical leakage: in vitro study

Aim: The aim of this study was to evaluate the influence of different irrigant agents (sodium hypochlorite only, sodium hypochlorite + EDTA and sodium hypochlorite + BioPure MTAD) for smear layer removal, on apical leakage. Materials and Methods: Three groups of premolars (n=49) were instrumented to size 45/. 04 ProFile, according to the irrigant agent and filled with gutta-percha and AH Plus sealer. Four premolars formed the control group. Leakage was measured, and was determined as μL/min-1.10 psi, by means of the fluid filtration method after the specimens had been stored at 37°C and 100 % humidity for 2 weeks. The data were submited to Tukey HSD test. Results: BioPure MTAD showed the highest leakage means, differing statistically from the other groups. The sodium hypochlorite group showed the lowest leakage values. Conclusion: Considering the experimental conditions and results observed, it was concluded that the removal of the smear layer did not contribute to a reduction in apical leakage. Clinical significance: The work confirms that sodium hypochlorite remains the irrigating substance of choice in endodontics. We can speculate that the use of solutions to remove the smear layer without sonic or ultrasonic physical agitation is insufficient.
Influence of Engineered Nanoparticles on Growth Parameters and Photosynthetic Pigments of Wheat (Triticum Durum L.) Under Salt Stress Levels

Salinity stress is a major limitation to global crop production. Wheat is one of the world’s crops has salt sensitive characteristics than other crops. Meanwhile, rapid advancement of nanotechnology is introducing more and more engineered nanoparticles (ENPs) in agricultural soil. While some negative effects of ENPs on plant health at very high concentrations have been reported, more beneficial effects at low levels are increasingly noticed. Calcium phosphate nanoparticles (CPNPs) are one of the most widely used nanoparticles to interact with ecosystem and of great interest in agricultural sciences. The current study evaluates the effect of Calcium phosphate nanoparticles on germination percentage and early growth rate of wheat germinated under sodium chloride stress. As compared to the control, the results clearly showed that germination percentage not affected after NPs treatments whereas growth, fresh mass and dry mass of seedlings were highly increased at low levels of CPNPs. As salt concentration increased, chlorophyll a, b and carotenoids contents decreased. The results revealed that CPNPs interacted with salt stressed seedlings caused an increasing in photosynthetic pigments as compared to the control.
Prevalence of anemia and its associated risk factors among urban school children of Chennai/ Tamilnadu

Introduction: Anemia is one of the major public health problems among adolescence age group. In modern society intake of locally available of junk foods is common among different age groups which can lead up to other non communicable disorders in adults. On the other hand there is lot of low socioeconomic population living in urban area and their children are studying in urban schools that are exposed to commonly available neighboring foods around the school premises. These children when they don’t have better performance in their academic career they become school dropouts and hunt for daily jobs for their survival. This study was done to find out the prevalence of clinical manifestation of anemia and associated factors among urban school children. Materials and Methods: a cross sectional study design done on urban school children in saligramam south Chennai from 20152017. Results: Prevalence of anemia was found to be 53.4% (95% CI 48.4-58.3). Males students were found to more 62.8% compared to female students 37.2%. In terms of grading of anemia mild 130(33.3%) moderate 64(16.4%) and severe 14(3.6%) respectively and remaining were found to be normal. In this study all student in the government schools were from low socio economic background. a higher prevalence of anemia among the students who had open air defecation, not wearing regular foot wares and not maintaining regular hand washing and who have a habit of taking regular food from the locally available shops and overweight individuals. On clinical examination of the study participants of 390 individuals 204(52.3) revealed pallor of conjunctiva, tongue and nail bed. Most of the children had 254 (65.1) individuals had either of the clinical manifestation of anemia.

Evaluates the Efficiency of Interferon-Alpha Therapy for Different Time Intervals on the Levels of Iron in Serum Samples of Chronic Hepatitis C Patients

It was investigated that the Interferon-α (IFN-α) therapy to patients with hepatitis C are correlated with iron levels in serum. The aim and objective of this study was to test whether the iron levels in blood serum samples were decreased after IFN-α therapy for different time intervals. In present follow-up study, iron levels in serum samples of chronic Hepatitis C (HCV) patients before and after IFN-α therapy at different time interval (24-48 weeks) were evaluated. 160 females HCV patients were selected for follow-up study. Blood samples were collected from patients before and after treatment of IFN-α therapy. For comparative purpose, blood samples from healthy female subjects of the same age group were also collected. The serum iron was determined by electro thermal atomic absorption spectrometry, after microwave assisted acid digestion method. After INF-α therapy, HCV RNA level was undetectable in 32% and 58% patients, for 24-48 weeks, respectively. The level of Fe in serum samples were significantly reduced after longer period of treatment with INF-α (48 weeks).
Adhesively bonded joints in synthetic and natural fiber based composite materials : An overview

The use of adhesive bonding in structures made from composite materials has increased in recent years due to their various advantages such as uniform load distribution, ease of fabrication, lightweight design, good strength etc. In this paper, a review on research work that have been carried out on adhesively bonded joints of synthetic and natural fiber-reinforced polymer composite materials is presented. The influence of joint configuration, adhesive properties, overlap length and adherent thickness on joint behavior has been discussed. Additionally, failure analysis of the adhesively bonded joints under uniaxial quasi-static loading conditions is described. It is observed that joint strength is mainly affected by adhesive strength and overlap length. It is also seen that cohesive failure is predominant over adhesive failure in bondline area.
Ultrastructure of the Thyroid Gland in Bakerwali Goat (Capra hircus)

The present study was conducted on the 36 samples of thyroid gland divided into three groups based on the age of animals and irrespective of sex viz.Prepubertal (below 1 year), Pubertal (2-3 years) and Senile (above 5 years of age) containing 12 animals in each group. The study was conducted to understand the ultrastructural morphology and some of the changes in the components of the thyroid gland in goat with age. Follicular cells were cuboidal in prepubertal group but were flattened senile group. These cells remarkably showed highly dilated cisternae of rough endoplasmic reticulum which decreased in frequency with the age. Microvilli were short and sparse on the follicular cells and the number decreased in the older goats. Different sizes of apical vesicles of varying electron density were encountered that included colloid droplets, secretory vesicles and lysosomelike bodies and the appearance of these vesicles changed with age. Para follicular cells were encountered in the basal position between follicular cells in all age groups. Numerous dense cytoplasmic granules were observed and they were not apparently different and hence the general ultrastructural features of the thyroid of adult Bakerwali goat was similar to that of domestic animals.
Cytokines as Biomarkers in the Diagnosis of MDR TB Cases

Background: Cytokines play important roles in many physiological responses and are involved in the pathophysiology of a wide range of diseases. Because of their regulatory nature, their potential as therapeutic agents has been explored. Cytokines have pleiotropic and regulatory effects and participate in the host’s defense and in inflammatory and tissue reparation processes. Material and Methods: The study was conducted at the Department Of Microbiology, J.N. M.C, Aligarh, India.Different cytokines levels were measured in 65 samples of TB patients of whom 30 (46.1%) were new TB cases and 35 (53.8%) were suspected multi drug resistant (MDR) TB cases along with 15 BCG vaccinated healthy controls by ELISA (Diaclone France). Results: The serum concentration of TNF-α, IFN-γ, IL-1β, IL-6, IL10 & IL-12p70 in patients with active TB & MDR TB was elevated than in treatment patients (P < 0.001) and in controls (P < 0.001). Conclusions: These cytokines can be used as a biomarker for the diagnosis of MDR TB cases and for the prediction of differential treatment responses in new and under-treatment TB cases.
Effects of Ketamine and Midazolam on Emergence Agitation after Sevoflurane Anaesthesia in Children Receiving Caudal Block: A Randomized Trial

Introduction: Emergence agitation is a common post anaesthetic complication in children after sevoflurane anaesthesia. We aimed to compare the effects of ketamine and midazolam administered intravenously, before the end of surgery, for prevention of emergence agitation in children who received caudal block for pain relief under sevoflurane anaesthesia. Material and Methods: 100 American Society of Anaesthesiologists status I children aged 4-11 years scheduled for inguinal hernia repair, circumcision or orchidopexy were enrolled to the study. Anaesthesia was induced with sevoflurane 8% in a mixture of 50% oxygen and nitrous oxide. After adequate depth of anaesthesia, a laryngeal mask was placed and caudal block was performed with 0.5 mL kg−1, 0.125% bupivacaine. At the end of the surgery, ketamine 0.25 mg kg−1 or midazolam 0.03 mg kg− were given to their respective groups. Agitation was assessed using Paediatric Anaesthesia Emergence Delirium scale and postoperative pain was evaluated with modified Children's Hospital of Eastern Ontario Pain Scale. Results and conclusion: modified Children's Hospital of Eastern Ontario Pain Scale scores were found higher in midazolam group as compared to ketamine group at 0 minutes and 5 minutes while after 10 minutes, the scores became insignificant. Paediatric Anaesthesia Emergence Delirium scores were found to be higher in midazolam group at 0, 5 and 10 minutes as compared to ketamine group, but at 30 minutes, the delirium scores became comparable. Thus, ketamine was able to prevent Emergence Delirium as well as decrease pain scores better than midazolam following sevoflurane anaesthesia in children with caudal block.
OncOgenic high-risk human papillOmavirus detectiOn and evaluatiOn Of risk factOrs in the cervical intraepithelial neOplasia i Detecção Do papilomavírus humano De alto risco oncogênico e avaliação Dos seus fatores De risco nas neoplasias intraepiteliais cervicais grau i

Introduction: The cervical intraepithelial neoplasia grade I (CIN I) shows an important percentual of spontaneous regression (80%) and there is no universal consensus if these lesions should be treated or only monitored. Lesions at risk for progression are precisely those associated with high-risk HPV. Knowing which CIN I are related to these viruses may be one of the determining factors for the decision to treat or not. Objective: To determine the prevalence of high-risk HPV in women with CIN I and to evaluate if there is an association between the presence of the virus and some risk factors. Methods: Cross-sectional descriptive study. We evaluated 55 women with histological diagnosis of CIN I. All of them were previously submitted to HPV-DNA testing. Results: 25 out of 55 (45.5%) women analyzed were positive for high-risk HPV. The virus infection was related with higher level of education, smoking and history of sexually transmitted diseases. Other risk factors like age, number of sexual partners, age at first sexual intercourse, use of hormonal contraceptives, and immunosuppression condition did not show a relation to the high-risk HPV infection. Conclusions: The prevalence of high-risk HPV in women with histological diagnosis of CIN I was 45.5%. HPV-DNA detection was associated with smoking, history of sexually transmitted diseases, and higher level of education.
A copper P-type ATPase in Methylococcus capsulatus ( Bath ) has a role in copper homeostasis

Methylococcus capsulatus (Bath) is a Gram-negative, spherical-shaped bacterium that utilizes methane, a potent greenhouse gas, as its carbon and energy sources thus alleviating global warming. Copper is an essential trace element for the physiology this bacterium, however, it is highly toxic at elevated levels. Therefore, copper homeostasis must be tightly regulated. Out of different proteins involved in copper homeostasis, CopA, a coppertranslocating P-type ATPase (CopA), which is involved in copper transport across membranes of various organisms. Little work has been done on copper homeostasis in methanotrophs and in particular on Methylococcus capsulatus. The current study addressed the disruption of a CopA2 homologue (MCA0805; copA2) in M. capsulatus by insertional inactivation. The results showed that the phenotype of the resulting mutant, M. capsulatus ΔcopA2, was copper sensitive; its growth was reduced at a copper concentration of 30 μM, and accumulated three-fold more copper intracellularly compared to the wild-type strain. No observed phenotypic difference between the mutant strain and wild-type related to growth at different silver concentrations. These findings indicate that M. capsulatus CopA2 has a pivotal role in copper homeostasis and confers intrinsic copper resistance. Keywords— CopA; Copper homeostasis; P-type ATPases; Methylococcus capsulatus.
