Composite Four-Terminal Floating Nullor with Variable Voltage and Current Gains

A design technique for the practical implementation of a variable four-terminal floating nullor (FTFN) is presented, which contains three operational mirrored amplifiers (OMAs) and four grounded resistors. The proposed FTFN provides tunable both voltage-gain and current-gain with constant bandwidth property by varying the value of a single grounded resistor. PSPICE simulation results that agree with the theoretical analysis are obtained by modeling a variable-gain FTFN using commercial AD844 ICs. The aim of this paper is to propose a circuit technique for the practical implementation of the FTFN with variable voltage and current gains. The circuit realization uses only three operational mirrored amplifiers (OMAs) and four grounded resistors. The proposed tunable FTFN offers independently variable dc voltage and current gains while remaining a constant bandwidth. Moreover, it is interesting to show that the dc gains of the circuit can be tuned by adjusting grounded resistors without effecting the useful bandwidth. The performances of the proposed variable-gain FTFN using a commercial AD844 ICs are given with the simulation results, which will show that the characteristics of the resulting circuit become tunable.
Study on footstep power generation using piezoelectric tile

Electrical energy is important and had been demand increasingly. A lot of energy resources have been wasted and exhausted. An alternative way to generate electricity by using a population of human had been discovered When walking, the vibration that generates between the surface and the footstep is wasted. By utilizing this wasted energy, the electrical energy can be generated and fulfill the demand. The transducer that use to detect the vibration is a piezoelectric transducer. This transducer converts the mechanical energy into electrical energy. When the pressure from the footstep is applied to the piezoelectric transducer, it will convert the pressure or the force into the electrical energy. The piezoelectric transducer is connected in series-parallel coonection. Then, it is placed on the tile that been made from wood as a model for footstep tile to give pressure to the piezoelectric transducers. This tile can be placed in the crowded area, walking pavement or exercise instruments. The electric energy that generates from this piezoelectric tile can be power up low power appliances.
Vanadium rutin complex sensitizes breast cancer cells via modulation of p53/Bax/Bcl2/VEGF correlated with apoptotic events

In pursuit of a novel approach in breast cancer therapy, we explored the ability of vanadium-rutin complex to eradicate cancer by efficiently targeting various apoptotic pathways on human breast cancer cell lines. We provide direct proof of the chemotherapeutic potential of the vanadium-rutin complex by activating p-53 dependent intrinsic apoptosis and modulating the VEGF pathways. The complex was also capable of binding and cleaving CT-DNA at different concentrations. The complex was able to inhibit cell viability at 100 and 150 μM doses in both MCF7 and MDA-MB-231 cells. Furthermore, the complex successfully initiated apoptosis in both cell lines by activating the p53 dependent intrinsic apoptotic pathway. In vitro studies also established that the complex modulated p53, Bax, Bcl2 and VEGF expressions and induced DNA fragmentation in both the cell lines.

Presepsin as a New Marker for Early Detection Neonatal Sepsis in Al-Quwayiyah General Hospital Riyadh, KSA

Background: Early detection and start of antibiotic therapy neonatal sepsis (N.S) dramatically improves outcomes, so it is important to perform fast, reliable and specific early laboratory biomarkers. Aim: This study aimed to detect the prevelance, the risk factors, hematology profile, microbial profile of neonatal sepsis patients and also investigate the value of PCT and CRP, in comparison to presepsin in establishing the early diagnosis of neonatal sepsis. Methods: A cross sectional study was performed from March to September 2019 in Al Quwayiyah General hospital involving 120 neonates who were classified into 3 groups. The patients groups were: Proved N.S, suspected N.S and control healthy neonates, classified depending on Tollner score. Haematology profile and blood culture for each neonate were done. CRP, PCT and presepsin values were analyzed, compared, and their effectiveness as diagnostic markers was determined. Sensitivity, specificity, positive, and negative predictive values of the markers were calculated. Results: The prevelance of neonatal sepsis was 20.8%. 75 neonates were males and 45 neonates were females. 74 neonates were preterm, while 46 were full term. Gestational age in weeks was 31.1±5.9w for neonates with proved sepsis, 32.4±6.7w for neonates with suspected sepsis and 36.4±4.4w for control group. The mean birth weight was 1740±105.3 g for neonates with proved sepsis, 32.4±6.7 g for neonates with suspected sepsis, 2.650±205.2 g for control group. 36 babies suffered from respiratory distress syndrome, 10 had jaundice, 8 had cough, 28 had fever and 8 complained of other symptoms. Blood cultures were positive for all patients of proved sepsis. The identified bacteria included Gram positive bacteria 22(55%) which were Coagulase negative staph. 13(32.5%) followed by Staphylococcus aureus 4(10%) while Gram negative bacteria 15(37.5%) which were E. coli 5(12.5%) followed by Klebsiella peumoniae and also fungal infection (Candida species) detected in 3(7.5%) cases. There was significant difference between the mean and standared deviation of CRP, PCT and presepsin levels in proved and suspected N.S. groups when compared with healthy controls (P< 0.05). CRP sensitivity and specificity (72%, 61% respectively) which were less useful in diagnosis of neonatal sepsis compared to presepsin which has the highest sensitivity and specificity (95%, 81% respectively) followed by procalcitonin with sensitivity and specificity (90%, 69% respectively). Conclusion: The prevalence of neonatal sepsis among all admitted neonates in Al-Quwayiyah general hospital was 20.8%. Our results also detected higher sensitivity, specificity and positive and negative predictive values for presepsin more than and PCT CRP in the diagnosis of NS.
PSYCHOGRAPHICS STUDY ON THE VOTING BEHAVIOR OF THE CEBUANO ELECTORATE

This study identified the attributes of a presidentiable/vice presidentiable that the Cebuano electorates preferred and prioritized as follows: 1) has a heart for the poor and the needy; 2) can provide occupation; 3) has a good personality/character; 4) has good platforms; and 5) has no issue of corruption. It was done through face-to-face interview with Cebuano registered voters randomly chosen using a stratified sampling technique. Canonical Correlation Analysis revealed that there was a significant difference as to the respondents’ preferences on the characteristic traits of the presidential and vice presidential candidates across respondents with respect to age, gender, educational attainment, and economic status. The strength of the relationships were identified to be good in age and educational attainment, moderate in gender and weak in economic status with respect to the characteristics of the presidentiable. Also, there was a good relationship in age bracket, moderate relationship in gender and educational attainment, and weak relationship in economic status with respect to the characteristics of a vice presidentiable. The strength of the said relationships were validated by the established predictive models. Moreover, perceptual mapping of the multivariate correspondence analysis determined the groupings of preferred characteristic traits of the presidential and vice presidential candidates across age, gender, educational attainment and economic status. A focus group discussion was conducted and it validated the survey results. It enumerated more characteristics that explained further the voting behavior of the Cebuano electorates.
OVERVIEW OF KUBERNETES CNI PLUGINS PERFORMANCE

Containerisation and microservices architecture are getting momentum in nowadays ICT field. Containers are deployed in both public and private cloud environments and usually for flexibility purposes are deployed in VM (Virtual Machines) environment. Microservices have a demand on a high number of containers which requires orchestration and Kubernetes is one of the most popular choice. However, Kubernetes does not offer networking solution and it is provided by CNI (Container Networking Interface) and its’ plugins. In order to choose best plugin their performance needs to be evaluated. In this paper nine most popular CNI plugins TCP and HTTP protocols performance is evaluated in virtualised VMware ESXi and physical data centre environment. The results help to choose which CNI plugins to use either in virtualised or physical data centre environment.
COMMUNICATION-COMPUTING-CONTROL (3C) SYSTEM FOR PROMOTING DEMAND SIDE MANAGEMENT (DSM)

: Today, the demand side management (DSM) is an integral part of resource planning or least cost planning. The resources are developed in such a way as to minimize present and future costs. DSM techniques have been implemented in many developed countries successfully. However, the implementation of DSM has been limited due to lack of Information, Poor Power Quality, Reliability, Tariff, Small Scale Sector and Unavailability of Efficient Equipment in developing countries etc. The implementation of pricing and billing schemes is one of the objectives of smart grid. In this paper, we focus on various techniques for promoting DSM with integrated of Communication-Computing-Control (3C) system under the area of ICT (Information and Communication Technology) to consumers at electricity market and increasing energy efficiency in Smart Grid / Modern Grid.
Productivity and Sustainability Effects of Conservation Agriculture

The broad idea of conservation agriculture (CA) implies the use of more crop residues, less tillage, soil degradation, etc. It has been known for many years but CA practice still developing and improving. Early development was concerned almost exclusively with residue, tillage and the maintenance of yields. More recently, there has been much work on controlled traffic and bed farming systems to address issues such as soil compaction, and allow further improvements in yield without additional inputs. The greater productivity and sustainability of controlled traffic farming (CTF) zero tillage systems is discussed in this paper, which also shows why these systems will reduce the greenhouse gas and other environmental issues of crop production. By avoiding the contradictions of earlier systems, they become closed to justifying the title "conservation agriculture".
Incorporating Cannibalization into Pricing Optimization Using Choice Data: An Application to the Pricing of Mobile Broadband Services

Price differentiation may not be as effective in increasing profitability due to imperfect segmentation, arbitrage, and, cannibalization. Cannibalization takes place when customer with higher willingness-to-pay buys lower-priced product. This research proposes an approach to incorporating cannibalization into pricing optimization using choice data. From choice data, individual level utilities are estimated using hierarchical Bayes and individual choice is predicted using randomized first choice simulation. Individual choices are then aggregated to obtain the demand function. The novelty of this research is in the way cannibalization is incorporated into the pricing optimization. Instead of integrating cannibalization into the demand function or representing it as a separate component in the optimization formulation, in this research, cannibalizing products are incorporated into the simulation scenario as competing products, based on which the demand functions used in the optimization are derived. This approach is more direct and realistic than those in the previous research. The approach was implemented in a case study of mobile broadband services in Indonesian price-sensitive market. The result shows that two-fare-class price differentiation incoporated with product differentiation increases total contribution of about 60% compared to single-fare-class policy. Furthermore, it is also shown from our case study that starting from a three-fare-class policy, through iterations, our approach suggests that policy with two-fare-class results in a not significantly different total contribution.

The experimental group gain was 0.6247, while the control group gain was 0.2803. Thus, the TPSR model is needed in increasing the student’s responsibility.
Compactlike Kink Solutions in Reaction Diffusion Systems

We introduce and demonstrate theoretically the existence of discrete compact-like kink solutions in a class of discrete reaction-diffusion systems with a nonlinear coupling. Numerical simulations show that the extent of such solutions is related only to the coupling parameter, and that propagation failure mechanism occurs for non zero critical coupling value Dc like for discrete reactiondiffusion system with linear coupling. We quantify this critical coupling value and propose an electrical device allowing to verify experimentally our theoretical predications.
Prevalence of Failed Inferior Alveolar Nerve Block (IANB) in Achieving Pulpal Anaesthesia in Mandibular Molars with Symptomatic Irreversible Pulpitis

Introduction: Patient comfort during root canal treatment is immense for patient cooperation and endodontist efficiency. Establishing the high prevalence of failure of IANB injections in providing pulpal anaesthesia, will most likely support the investigation of supplemental techniques to ensure patient comfort. Objectives: The study aimed to evaluate the prevalence of failed Inferior Alveolar Nerve Block (IANB) injections in achieving pulpal anaesthesia in mandibular molars diagnosed with symptomatic irreversible pulpitis when administered alone. Methods: This study involved fifty patients, diagnosed with symptomatic irreversible pulpitis in their mandibular first and second molars. IANB injection using 2% lidocaine with 1:100,000 epinephrine was administered to anesthetize the acutely inflamed teeth before commencing root canal treatment. Lip and tongue numbness was checked subjectively after injection to ensure successful IANB injection. Objectively, cold test was performed after 15 minutes and pain level was recorded using Visual Analogue Scale (VAS). Success was defined as no pain response by (VAS) during cavity preparation, endodontic access, or initial instrumentation. Results: Although, majority of patient (96%) expressed surrounding soft tissue numbness, only 73% did not feel any pain during initiating root canal treatment. Conclusions: IANB injection alone is not enough to provide profound pulpal anaesthesia in acutely inflamed mandibular molars; therefore, supplemental injections are required to achieve patients comfort during treatment.
Desire for Sexual Variety in the Greek Cultural Context

Human beings exhibit considerable variation in their approach towards the number of sexual partners they wish to have. One consistent predictor of this variation has been sex—men desire more sexual partners than women. The current study aims to examine whether this effect is present in the Greek cultural context. In particular, a sample of 1414 Greek and Greek-Cypriot participants were asked about their desired number of sexual partners at different stages in their lives. It was found that men preferred significantly more partners than women. It was further found that men were divided in their preferences, with about half preferring several, and about half preferring a few lifetime sexual partners. On the other hand, about three-thirds of women preferred a few lifetime sexual partners with about one-third preferring several lifetime partners.
Endonasal dacryocystorhinostomy: evaluation of the anatomical and functional results

Background: Dacryocystorhinostomy is a novel surgical technique for NLD obstruction performed by external and endonasal approach. Both procedures have variable success rates and advantages or disadvantages. The objectives were to study functional and anatomic outcomes of endoscopic DCR and to assess degree of ostium shrinkage in postoperative period. Methods: Prospective study comprising 68 patients of NLD obstruction with 70 procedures performed during the period of October 2014 to October 2016. Various dimensions of bony neo-ostium were recorded intraoperatively and during 1st and 3rd month follow up. Mitomycin C was applied in 37 cases. Degree of ostium shrinkage and its correlation with surgical success was studied. Outcome of study was measured as functional and anatomical success. Results: 68 patients in age range of 7 to 71 years. Mean intraoperative height and width were 12.0±2.08 mm and 5.17±0.82 mm respectively and intraoperative surface area of ostium was 62.77±17.27mm 2 . The study showed strong positive correlation between initial and final ostium size. The final ostium irrespective of its size, if patent does not result in recurrence of symptoms and can be considered as success. In the present study, functional and anatomical success was 97.14% and failure rate was 2.86%. Conclusions: Both functional and anatomical success require creation of patent neo-ostium, although the intraoperative size of ostium is not the deciding factor for final outcome. Complete exposure of lacrimal sac, adequate mucosal preservation, good marsupialization and mucosal apposition are the some of the crucial factors responsible for stable ostium patency and hence the surgical success.
Chronic radiation-induced brain changes after irradiation of endocranium

Introduction: Irradiation is an essential part of therapy for brain malignant tumors that can prolong life for terminally ill patients. However, it causes radiation-induced complications, divided into acute, early delayed and late complications, that all vary on the applied radiation dose. Aim: The aim of this research was to determine the type and frequence of radiation-induced brain changes after irradiation of endocranium, and to determine correlations between the type of the changes, the irradiation dose and the time passed. Material and methods: This retrospective study included 41 patients of both sexes. The study was performed in the Center for Imaging Diagnostics of Oncology Institute of Vojvodina, using the BIRPIS database. Magnetic Resonance Imaging (MRI) scans consisted of: T2 axial, FLAIR axial, T1 pre-contrast axial, SWI, and T1 axial 3D MP-RAGE post-contrast tomograms. Evaluated changes were: cavernoma, angioma, gliosis, aneurysm, hemorrhage, hydrocephalus and other. Methods of descriptive statistics were used for the analysis. Results: The most common change in this study was gliosis (92.68%), followed by cavernoma (53.65%), hydrocephalus (26.83%) and angioma (21.95%). Hemorrhage and aneurysm were not found. Dilated perivascular spaces were found in 80% of the patients; this finding has not yet been described in this group of patients. Conclusion: Dilated perivascular spaces represent frequent post-irradiation sequelae in the white matter of the brain in treated patients, just after gliotic changes, that are the most frequent complication. Further studies are needed to explain the pathophysiologic mechanism of these changes.
Perception of Virtual Facial Expressions: Response Times and Accuracy

Communication has come a long way extending from human-human interaction to human-computer interaction. Some communicational skills translate well in this extensions while others do not. This is a comparative study comparing the recognition of facial expressions in real life faces and realistic virtual faces measuring the time it takes to recognize said expression as well as the accuracy at which we do so. This is done through within-subject user testing on the seven universal facial expressions. The conclusion is that there are multiple similarities in the way we perceive facial expression of virtual characters and real life ones. Such as the misclassiﬁcations we make and how the complexity of the expression impacts the response time. However further research is needed to make deﬁnitive statement on the difference in our ability to recognize facial expression of virtual characters compared to real life ones.
