Chacha stream cipher implementation for network security in wireless sensor network

In the 4.0 industrial revolution, technologies are designed to be able to connect to the internet. These technologies should be able to exchange data between them using sensors and others. One of the ways to send it is by the wireless sensor network. However, involving the internet in exchanging data needs security guarantees. Three things must meet in network security, that is confidentiality, integrity, and availability. Cryptography use for the confidentiality of the information that will be sent by the user. In this research will be using the symmetric cryptography for network security on wireless sensor networks. In addition to network security, symmetric cryptography method will be used also consider energy efficiency on a wireless sensor network. Chacha stream cipher as symmetric cryptography will be used as a method of messages encryption. Experiments in this research used NS-3 as a network simulator. Results of the tests show that the purpose method has a computation time of 0.2385 ms and the second-fastest after the rabbit cryptographic process. Chacha LR WPAN simulation process has a computation time of 17.6199 ms.
Microbiological Analyses of Kunu Drinks Locally Produced and Sold in Calabar, Southern Nigeria

Kunu is a non-alcoholic Nigerian beverage produced locally from cereals. The method of preparation, as well as the key ingredients and spices added as flavoring agents are always not standardized. This study was carried out to investigate the microbial quality of kunu drinks locally produced and sold in Calabar and to determine the antimicrobial susceptibility profile of the isolates. A total of 9 kunu samples were collected and analyzed by standard microbiological methods. The pH of the samples, microbial colony counts and antimicrobial susceptibility profile were determined by standard methods. The pH values of the samples ranged from 3.80-4.20. The total viable counts for mesophilic bacteria, coliform and fungi ranged from 3.0-5.7x10 3 cfu/ml, 1.0-2-2x10 3 cfu/ml and 5.1-8.6x10cfu/ml respectively. The microorganisms isolated include bacteria; Staphylococcus aureus 4(10%), Lactobacillus sp. 9(22.5%), Proteus sp. 3(7.5%), Pseudomonas aeruginosa Original Research Article Etang et al.; JAMB, 5(2): 1-8, 2017; Article no.JAMB. 36169 2 3(7.5%), Streptococcus sp. 4(10%), Salmonella sp. 5(12.5%), Bacillus sp. 6(15%) and Escherichia coli 6(15%), and fungi; Saccharomyces sp. 6(28.5%), Fusarium sp. 2(9.5%), Aspergillus sp. 4(19%), Penicillium sp. 4(19%) and Rhizopus sp. 5(24%). The results of antimicrobial susceptibility test showed 100% resistance of the bacterial isolates to Clindamycin, Erythromycin and Cefuroxime and 100% sensitivity to Imipenem, Ofloxacin and Amoxicillin. The fungal isolates, Aspergillus sp. and Saccharomyces sp. showed 100% sensitivity to Griseofulvin, Ketoconazole and Fluconazole at varying concentrations while the rest were resistant. The results of this study revealed contamination of kunu drinks from many sources, most commonly microorganisms which could present a significant health risk to the consuming population. Therefore, it is recommended that good hygiene and sanitation practices should be enforced at all levels during preparation and processing of kunu drinks to mitigate microbial contamination of the finished product and curtail the incidence of food-borne illnesses.

Effect Of Inflammatory Pain On Alcohol-Induced Dopamine Release In The Nucleus Accumbens: Behavioural Implications In Rat Models

Recent studies have drawn the attention to the link between Alcohol Use Disorder (AUD) and the presence of pain. Indeed, the correct management of pain in patients with a previous history of AUD has been reported to decrease the risk of relapse in alcohol drinking, suggesting that in this prone population, pain may increase the vulnerability to relapse. Previous data in male rats revealed that inflammatory pain desensitizes mu opioid receptors (MORs) in the ventral tegmental area (VTA) and increases intake of high doses of heroine. Due to the relevant role of MORs in alcohol effects, we hypothesize that pain may also alter alcohol reinforcing properties and therefore affect alcohol relapse in male rats. Our microdialysis studies show that the presence of inflammatory pain blunted the increase of extracellular dopamine levels in the Nucleus Accumbens induced by 1.5g/kg of ethanol (s.c.). Moreover, we also revealed that the administration of 52 nmol of ethanol into the VTA failed to induce place preference only in inflammatory pain-suffering animals, and a higher dose (70nmol) was necessary to reverse this effect. Finally, we evaluated the effect of inflammatory pain on the alcohol deprivation effect (ADE) in long-term ethanol-experienced male rats. After four cycles of free ethanol intake and abstinence periods, inflammatory pain induced ADE without affecting its magnitude. These intriguing data reveals the impact of pain on neurochemical and behavioral effects following alcohol administration but also underscore the necessity of finding an appropriate paradigm to determine the long-term behavioral consequences.
Predicting long-term multicategory cause of death in patients with prostate cancer: random forest versus multinomial model

Patients with prostate cancer more likely die of non-cancer cause of death (COD) than prostate cancer. It is thus important to accurately predict multi-category COD in these patients. Random forest (RF), a popular machine learning model, has been shown useful for predicting binary cancer-specific deaths. However, its accuracy for predicting multi-category COD in cancer patients is unclear. We included patients in Surveillance, Epidemiology, and End Results-18 cancer registry-program with prostate cancer diagnosed in 2004 (followed-up through 2016). They were randomly divided into training and testing sets with equal sizes. We evaluated prediction accuracies of RF and conventional-statistical/multinomial models for 6-category COD by data-encoding types using the 2-fold cross-validation approach. Among 49,864 prostate cancer patients, 29,611 (59.4%) were alive at the end of follow-up, and 5,448 (10.9%) died of cardiovascular disease, 4,607 (9.2%) of prostate cancer, 3,681 (7.4%) of Non-Prostate cancer, 717 (1.4%) of infection, and 5,800 (11.6%) of other causes. We predicted 6-category COD among these patients with a mean accuracy of 59.1% (n=240, 95% CI, 58.7%-59.4%) in RF models with one-hot encoding, and 50.4% (95% CI, 49.7%-51.0%) in multinomial models. Tumor characteristics, prostate-specific antigen level, and diagnosis confirmation-method were important in RF and multinomial models. In RF models, no statistical differences were found between the accuracies of development versus cross validation phases, and those of categorical versus one-hot encoding. We here report a RF model that has an accuracy of 59.1% in predicting long-term 6-category COD among prostate cancer patients. It outperforms multinomial logistic models (absolute prediction-accuracy difference, 8.7%).
Estudio piloto sobre la percepción de la brecha de género en estudios de ingeniería informática

The gender gap is one of the main problems present in today's society. The equality, not only of women but of different gender identities, is part of the priorities of the European Union, as well as of a large part of the developed countries. In particular, in the areas of science, technology, engineering, and mathematics (STEM), the gender gap is visible in both the academic and professional fields. In higher education, according to a worldwide study, only 35% of all students enrolled in STEM studies are women. There are a large number of initiatives that work to reduce the gender gap in various contexts, from early childhood and primary education to the business sector. The present work presents a pilot study that allows validating the GENCE questionnaire defined in previous works. Specifically, it has been applied in the Degree in Computer Engineering of the University of Salamanca in order to know the perception of its students about the gender gap after applying a set of actions to promote diversity in the field of engineering.
Obtaining Mn-Co Alloys in AISI 430 Steel from Lithium-Ion Battery Recycling: Application in SOFC Interconnectors

The recycling of exhausted lithium-ion batteries from mobile phones originate five solutions with different Co and Mn proportions that were used as electrolytic solutions to obtain Mn-Co spinel coatings on the surface of AISI430 stainless steel. The coatings are intended to contain chromium volatility in the working conditions of Solid Oxide Fuel Cells (SOFC) metallic interconnectors. Potentiostatic electrodeposition was the technique used to obtain Mn-Co coatings from low concentration electrolytes at pH = 3.0 and potential applied −1.3 V. Charge efficiency data were used for sample optimization. Three optimized samples were subjected to oxidation heat treatment at 800 °C for 300 h and then characterized by XRD, SEM and EDS. The results showed that the addition of manganese ions instead of cobalt ions in the electrolytic bath produces more stable and well-distributed deposits as the ratio of the two ions becomes equal in the electrolytic bath. Thin, homogeneous and stable spinel coatings (Mn, Co)3O4 2.8 μm and 3.9 μm thick were able to block chromium volatility when exposed to SOFC operating temperature.
TERAPI SULIH HORMON ALAMI UNTUK MENOPAUSE

Ada perbedaan sikap terhadap masalah menopause. perempuan perkotaan lebih bersikap positif.makin cepat menopause makin baik, karena ibadahnya tidak terganggu lagi. Sebaliknya, perempuan pedesaan bersifat negatif karena kehidupan mereka sangat bergantung kepada suami baik dalam hal fisik, ekonomi, maupun sosial. Bagi mereka yang mengangap menopause sebagai proses menuju ketuaan, menopause identik dengan hilangnya daya tarik (Martaadisoebrata, 2005). Terapi sulih hormon merupakan pilihan untuk mengurangi keluhan pada wanita dengan keluhan sindroma menopause. Terapi sulih hormon juga dapat mencegah berbagai keluhan yang muncul akibat menopause, vagina kering, dan gangguan pada saluran kandung kemih. Penggunaan terapi sulih hormon juga dapat mencegah perkembangan penyakit akibat dari penurunan hormon estrogen seperti osteoporosis dan jantung koroner. Dengan demikian pemberian terapi sulih hormon, kualitas hidup dapat ditingkatkan sehingga memberikan kesempatan untuk hidup nyaman secara fisiologis maupun psikologis (Mulyani, 2013). Contoh makanan mengandung fitoestrogen tertinggi adalah biji minyak dan kacang- kacangan, kedelai, benih lenan seperti lignan, benih dan kacang : biji wijen, biji bunga matahari, chestnut, walnut, kacang pistachio. kacang tanah, almond, pistachio, hazelnut kacang Brasil dan kacang mede, minyak zaitun, bawang putih, kacang merah, buncis, kacang, bawang, brokoli, kubis, kering plum, tauge kacang hijau, stroberi, raspberry, kacang hijau dan mete, berbagai jenis sereal. Di Indonesia, yang umum dijumpai adalah beras merah, beras putih, jagung, gandum, dan sorgum. Kata kunci : terapi, sulih hormone, menopouse
Care-criminalisation: The involvement of children in out-of-home care in the New South Wales criminal justice system

This article discusses the involvement in the New South Wales criminal justice system of a cohort of children in out-of-home care. The paper reports the findings of a four-year research project that investigated the relationship between the child welfare and justice systems as experienced by a cohort of children in the New South Wales Children’s Court criminal jurisdiction. Analysis of 160 case files identified that children in out-of-home care appeared before the Children’s Court on criminal charges at disproportionate rates compared to children who were not in out-of-home care. The out-of-home care cohort had a different and negative experience of the justice system, entering it at a significantly younger age and being more likely to experience custodial remand, than children who had not been in out-of-home care. While both cohorts shared many of the risk factors common to young offenders appearing before the Children’s Court, the out-of-home care cohort experienced significant additional disadvantage within the care environment (‘care-criminalisation’), such that living arrangements designed to protect them from harm instead created the environment for offending. The paper concludes by arguing that a paucity of research exists regarding the drivers and dynamics of care-criminalisation and that more research is needed to explore the criminogenic impacts of a childhood spent in out-of-home care.
The commissioner’s perspective: the lived realities of commissioning children’s preventative services in England and the role of discretion

Commissioning remains the dominant process by which England’s state and third sector financial relationships are managed, attracting much criticism and debate. In response, the Civil Society Strategy (HM Government 2018) has called for a renewed focus on collaborative commissioning arrangements. However, the absence of much comment on commissioners suggests we have not paid enough attention to the role of the individuals who manage these processes. Semi-structured interviews with 15 commissioners, responsible for children’s preventative services, provide new empirical evidence exploring commissioners’ lived experiences. Drawing on the notion of vertical discretion, which is an individual’s freedom from external control, versus horizontal discretion, which is an individual’s freedom for decision making, this article explores the space for commissioners’ individual discretion within the commissioning process. Findings highlight that greater consideration of the role discretion has in commissioning processes can add some insight into how more collaborative commissioning arrangements may be achieved at a local level.

Methods: A Medline (PubMed) search was conducted and articles from 2002 and onwards was chosen. Conclusion: The current understanding of the predisposing factors and developmental phases of osteomyelitis of the jaw is insufficient. A widely diagnostic consensus is needed if reported data are to be used in meta-analyses.
Global risk factors affecting performance of construction firms in Abuja, Nigeria

The study assessed the Global Risk Factors (GRFs) affecting performance of Nigerian construction firms, with a view to identifying the most severe and appropriate risk response techniques. In order to achieve this aim, the severity of GRF across different categories of firms, and the risk response techniques most suitable for each GRF were examined. A total of 105 questionnaires were administered out of which a total of 49 were fully completed and returned. Descriptive statistics was used to analyse the data collected using Likert scales, while Analysis of variance was used to evaluate the similarities/differences in the views of different categories of construction firms. The findings show that most construction firms consider payment delays (mean = 2.65), poor project scope (mean = 2.40) and inadequate design information (mean = 2.39) as the most severe GRF affecting the performance of Nigeria construction firms. It was also discovered that, despite the high likelihood and impact of GRF such as; payment delays, design changes, and inflation/bank Interest rates amongst others, most firms still opted to “accept” them. On the other hand, poor project scopes, strikes, failure to meet clients need and all factors related to unethical practices were “avoided”, while all legal related risk factors were “mitigated”. It is hoped that these findings will help construction firms in developing countries such as Nigeria to be more aware of the effect of GRF in order to be able to assess them effectively before embarking on construction projects. Keywords: Global Risk Factors, Probabiity-Impact Metrix, Negative Risk, Risk Management, Semi-Quantitative Technique
Macrofaunal communities in the Gioia Canyon (Southern Tyrrhenian Sea, Italy)

Abstract Submarine canyons play pivotal roles in the physical, biological and ecological processes of coastal areas, especially in closed or semi-closed basins as the Mediterranean Sea, influencing the biodiversity and the abundance of the benthic fauna. On February 2013, during the Tyrrhenian Gravity Flows (TyGraF) campaign, samples have been collected along the Gioia Canyon Basin (Italy) with the aim to describe the taxonomical composition and the abundances of the macrobenthic assemblages, filling the gap of knowledge in this area. A total of 93 taxa were identified, and the Annelida was the phylum with the highest number of specimens and most diversified (46 taxa). The polychaetes Sternaspis scutata, Prionospio cirrifera and Monticellina sp. , the bivalves Thyasira sp.1 and Saccella commutata and the amphipods belonging to the genera Ampelisca and Harpinia showed the highest densities in the studied area; however, results suggest low values of the abundances of the macrobenthos if compared with those generally reported for other canyons, both inside and outside the Mediterranean Sea. The marine biotic index (AMBI) highlights that the canyon system and the surrounded area were slightly disturbed and characterized by a high percentage of tolerant taxa. This study is the first baseline for future analyses of the macrobenthic communities of this area.
Birincil Membranöz Nefropatide C4d Varlığı ve Yoğunluğunun Böbrek Hasarlanma Derecesi ile Birlikteliği

OBJECTIvE: The aim of this study was to evaluate the correlation between glomerular C4d staining and the demographic, clinical and histopathological findings in patients with primary membranous nephropathy (MN). MATErIAl and METhOdS: A total of 20 patients who underwent kidney biopsy and diagnosed as MN between 2005 and 2014 were included in this study. Patients were divided into two groups based on to C4d staining degrees and patterns. Those two groups were compared according to their demographical features, clinical follow-up, laboratory follow-up and histopathological findings. rESulTS: The percentage of segmental sclerosis (p=0.017), deposition of immunoglobulin A (p=0.044), and kappa and lambda proteins (p=0.029, p=0.049 respectively) were associated significantly with the negative-mild degree C4d staining group. Staining in a global pattern was statistically associated with intermediate-severe degree of C4d staining (p=0.001). The C4d staining patterns of the patients were then scored (segmental pattern one point, global pattern two point) and multiplied by the degree of C4d staining. The score of segmental/global pattern of staining factor was significantly higher within the intermediate-severe degree of C4d staining group (p<0.01). CONCluSION: Association of the global pattern and intermediate-severe degree of C4d staining suggests that immune deposition is more prevalent within the global pattern in primary MN. kEY wOrdS: C4d, Membranous nephropathy, Kidney injury
Reduction of polymerization shrinkage in adhesive restaurations

Composite materials used for the restoration of lost dental tissues fulfill almost all functional and aesthetic requirements. However, polymerization shrinkage still remains the main problem of light-curing composite resins. The consequences of this phenomenon are microfractures and microleakage in the marginal areas of the composite restoration. The aim of this paper is to present the most important methods for reducing polymerization shrinkage of adhesive restorations, based on the contemporary literature available. These methods include changes in the chemical composition of the composite, correct application technique of the adhesive-composite system and selection of the appropriate light curing protocol. In the last few years, composite materials have experienced significant changes in the chemical composition in order to compensate for their major shortcomings. By introducing pre-polymerized filler particles, alternative matrices based on silorane and ormocer, and new germanium-based photoinitiators, the degree of polymerization shrinkage has been significantly reduced. Optimal adhesive bond between the filling and the tooth can compensate volumetric shrinkage of material which occurs during polymerization. Numerous studies have shown that total-etch adhesive systems, in comparison with self-etch, form a better adhesive bond to hard dental tissues. Polymerization shrinkage can also be reduced and marginal adaptation improved by applying a stress-absorbing layer and preheated composite. With the use of modified light-curing protocols, such as soft start with reduced initial light intensity, and pulse-delayed with relaxation period, the negative effects of polymerization shrinkage and stress development can be further reduced, and the risk of microfracture formation minimized.
Effect of Perioperative Intravenous Infusion of Lignocaine on Haemodynamic Responses to Intubation, Extubation and Post-Operative Analgesia

Background: Intravenous bolus dose of lignocaine is generally used to reduce haemodynamic changes associated with intubation and extubation. Whereas lignocaine intravenous infusion has been used for post‐ operative analgesia. Aims and Objectives: To evaluate the effect of peri-operative intravenous infusion of lignocaine on hemodynamic responses to intubation, extubation and post-operative analgesia. Materials and Methods:80 patients undergoing elective laparoscopic cholecystectomy were included in our study and they were randomly divided into two groups, Group A and B of 40 each. Group A patients received 6 ml normal saline as bolus over 10 minutes followed by 6 ml/hour infusion, whereas in Group B, patients received preservative free 2% lignocaine 1.5 mg/kg IV bolus (made to a volume of 6 ml with normal saline) administered over a period of 10 minutes and thereafter an infusion at a rate of 1.5 mg/kg/hour (pre‐ diluted in normal saline made to a volume of 6 ml/hour. P < 0.05 was considered as significant. Results: Group B patients showed significantly longer mean pain‐ free post‐ operative period and also a less rise in pulse rate and mean arterial pressure compared to the Group A (P < 0.05) during intubation and extubation. Conclusion: Lignocaine infusion can successfully avert the change of haemodynamics resulting from intubation and extubation.
