Concerns regarding the safety and toxicity of medicinal plants - An overview.

All over the world, especially in developing countries herbal drugs are playing an important role in health care programmes.This is because they are being cheap and locally available. There is a general belief amongst the consumers globally that herbal drugs are always safe because they are "natural". However evidences suggests otherwise. The mere fact that a product is "natural" may not signify that the product is safe. Although limited evidence suggests that adverse effects associated with the use of herbal drugs are less likely to occur than with conventional drugs, theydo occur though usually mild and only affecting a small number of people. Recent evidence suggests that some of the herbs considered to be safe over the last many decades have proven to be associated with health hazards. Herbal remedies can act either as agonists or antagonists that potentiate some drug therapies. Therefore , an understanding of conventional drugs is an essential prerequisite for effective herbal therapeutics.The advancement of technology has enabled the scientists to detect minute amounts of carcinogenic and toxic chemicals in these herbs and recognize or evaluate potentially hazardous effects of some of the herbs which had been used in traditional medicine since centuries.
A Nipple Splint Using a Textile-Like Thermoplastic Cast

The demand for nipple reconstruction has been increasing with the proliferation of breast reconstruction. After reconstructing a nipple, it is crucial to apply a splint because one of the limitations of nipple reconstruction is loss of nipple projection over time [1]. Long-term projection of the reconstructed nipple is influenced by two factors: 1) contraction of the flap, which begins once the flap is raised; and 2) retraction of surrounding and underlying tissues [2]. External forces such as those from trauma can also distort the reconstructed nipple, leading to loss of projection. Therefore, a protective splint is necessary to ensure a successful outcome of this delicate reconstructive procedure. Currently, several different kinds of splint materials are available, each with its own benefits and drawbacks. We have devised a nipple splint using textile-like thermoplastic tape.
Community structure and population status of Drosera burmanii Vahl. with new distributional record in Tripura, India

Quantitative data of community structure and the current status of ecologically and economically important Drosera burmanii Vahl. Populations were gathered at Tripura, India, from two different stands, Suryamaninagar (Site i) and Ishanchandranagar (Site ii). The area of occupancy of Drosera in both sites was measured. A total of 31 species (26 genera of 18 families) were recorded to be associated with Drosera. Species richness index, dominance index, diversity index and evenness index from both sites were analyzed. The relative importance value (RIV) was calculated for all the species found in the study sites and was highest for Drosera. Individuals of Drosera were also categorized into mature, juvenile and seedlings based on the presence and absence of reproductive organ. This is the first report of the species from the Tripura region. Local ethno-medicinal use of the Tripuri tribe is also documented.

METHODS. Experimental RVO was induced in the right eyes of 40 rabbits using laser photothrombosis; the US experiment took place 48 hours later. Rabbits were randomly divided into four equal groups: USþCLP group, USþsaline group, CLPþsham US group, and no treatment group. The latter three groups acted as controls. Fundus fluorescein angiography and Doppler US were used to evaluate retinal blood flow.
A simulation model for the control of electric vehicles charging networks

This paper presents the details of software development and implementation of a simulation model to be used for performance analysis of the control applied for management of a plug-in electric vehicles charging network. The model is designed to provide an evaluation of the tested control algorithms in terms of efficiency and stability operation. Apart from the control algorithm evaluation the model can be used for assessment of required control modification. The model has been built using Java language under paradigms of object-oriented programming and test driven development.
That is how we do it around here: Levels of identification, masculine honor, and social activism against organized crime in the south of Italy

Masculine honor is an important cultural code in the south of Italy. Italian criminal organizations (COs) manipulate and exploit this code to maintain legitimacy among local populations and exert social control in the territory where they operate. This research tested the hypothesis that different levels of identification—the region and the nation—would have opposite associations with male honor-related values and, indirectly, with intentions to oppose COs collectively. Results from a sample of young southern Italians (N = 170) showed that regional identification positively predicted endorsement of male honor-related values, which in turn were associated with lowered intentions to oppose COs. In contrast, national identification negatively predicted male honor-related values, associated in turn with stronger intentions to oppose COs. These results also held when perceived risk and social dominance orientation were taken into account. Directions for future research are discussed. Copyright © 2015 John Wiley & Sons, Ltd.
Real-time translational control of a MEMS comb resonator

Closed-loop control has been successfully applied to a microelectromechanical systems (MEMS) lateral comb resonator device in real-time to perform impulse disturbance damping and sinusoidal position control, enabled by the use of a through-wafer optical microprobe to obtain position feedback. This result leverages the application of lifetime, in-situ control of MEMS in order to provide quality assurance of microsystems in safety critical applications. A position feedback signal produced by a through-wafer optical microprobe has been used for comb resonator system model identification by two independent methods to accurately determine the effective mass, damping, and spring constant values of the device. After accurate determination of system parameters, closed-loop impulse disturbance damping and proportional-integral-differential (PID) translational control were applied. Closed-loop control results presented indicate controllability of such microstructures and response times on the order of the natural frequency of the device.
Mode symmetry assessment of structurally non-uniform asymmetric coupled lines meandered for CMOS passive component design

This paper presents an accurate modeling of structurally non-uniform and asymmetric coupled lines meandered in RF CMOS integrated circuit, leading to the effective quantitative assessment of equivalent mode symmetry of even/odd mode that are often applied for designing microwave passive component. The four-port scattering parameter of the structurally asymmetric coupled CMOS lines was converted to the ABCD matrix, derived from a uniform pair of coupled lines. Thus the equivalent c-mode and π-mode representation of the structurally asymmetric coupled CMOS lines was obtained. The proposed extraction procedure was applied to two design examples of highly structural asymmetry, loosely and closely coupled CMOS lines, confirming that the electrical mode symmetry property was properly maintained for both case studies. The even mode and odd mode propagation characteristics of the two case studies were validated theoretically and experimentally, showing excellent mode symmetry was achieved for the structurally asymmetric coupled CMOS lines.
Dielectric fortification for wide-beamwidth patch arrays

This paper describes a general methodology for the design of wide beamwidth dual-polarized radiating patches. The half power beamwidth (HPBW) of a patch can be broadened by use of metallic boundaries surrounding the near-field of the patch. However, the use of metallic boundaries also reduces the overall frequency bandwidth of the radiator. This paper proposes dielectric fortification as an alternative approach for the beamwidth broadening of a dual-polarized patch antenna. It is demonstrated that significant broadening of pattern beamwidth is possible by incorporating a relatively thin layer of dielectric walls surrounding the radiator. A desirable broad beamwidth can be handily achieved by use of appropriate thicknesses of the dielectric walls. The effect can be further enhanced by incorporating metallic backing at the outside surfaces of the walls. This technique allows beam broadening without significant degradation in either the cross-polarized radiation pattern, or frequency bandwidth.
Tag Return Models Allowing for Harvest and Catch and Release: Evidence of Environmental and Management Impacts on Striped Bass Fishing and Natural Mortality Rates

Abstract Catch-and-release fisheries have become very important in the management of overexploited recreational fish stocks. Tag return studies, where the tag is removed regardless of fish disposition, have been used to assess the effectiveness of restoration efforts for these fisheries. We extend the instantaneous rate formulation of tag return models to allow for catch and release as well as harvest. The key point of our methods is that, given an estimate of the tag reporting rate, the fishing mortality rate (F) is separated into two components: the mortality on harvested fish and the “mortality” on tags (because the tags are removed) of fish released alive. The total fishing mortality rate for untagged fish is the sum of the Fs due to harvest and hooking mortality suffered by fish released alive. Natural mortality rates can also be estimated. Both age-independent models and age-dependent models are constructed, and the age-dependent models are illustrated by application to data from a study of striped .
NT-proBNP for heart failure diagnosis in primary care January 2013

The accurate diagnosis of heart failure (HF) presenting in primary care is difficult. Clinical assessment of symptoms and signs has limited sensitivity and specificity. Patients are often elderly with comorbidity, symptoms may be mild, and echocardiography may not be universally available [1, 2, 3]. Overdiagnosis of HF in the community is a well-documented phenomenon, with only a quarter to a third of patients with suspected HF, by general practitioners [4].
Iterative channel estimation for short preamble based OFDM/OQAM system

The existed preamble structure for orthogonal frequency division multiplex/offset QAM (OFDM/OQAM) system requires two zero-value guard symbols to guarantee ISI and ICI avoidance (equivalent to 3/2 complex value symbols in OFDM with cyclic prefix system), which leads to OFDM/OQAM system with low spectrum efficiency. In this paper, we shorten the preamble with 1 zero-value guard symbol to improve the spectrum efficiency. Unfortunately, the residual inter symbol interference (ISI) from neighbor symbols degrade the channel estimation performance. Therefore, we propose an iterative channel estimation method for OFDM/OQAM system to remove the residual ISI. Simulation results demonstrate that short preamble with iterative channel estimation is an effective method for OFDM/OQAM system. Furthermore, as the number of iterative time increasing, BER performance of short preamble with iterative channel estimation is approximately close to perfect channel estimation.
Model and algorithms for the real time management of residential electricity demand

Household Demand Side Management (DSM) systems play a key role in improving the efficiency of the entire electrical system. An efficient management of the energy resources can indeed allow spreading domestic energy loads in a smart way in order to reduce the peak power of the overall demand. To achieve this goal, home appliances and energy storage systems have to be controlled through the definition of energy plans for future periods (offline) and the real time control of energy resources (online). In this paper, we propose an optimization model and a set of heuristics for the online demand side management, to properly react in real time to events which were unexpected in a previous offline stage of the home management system, such as wrong weather forecasts or user's misbehaviours. The final goal is to reschedule the energy consumption and production coherently with the energy plan defined in the offline phase, taking into account the real production of renewable energy sources and the capacity of storage devices. Along with the heuristics, we show the numerical results obtained by applying them on realistic instances of the problem.
A novel approach to enhance performance of Linux-TCP Westwood on wireless link

Now a day's use of wireless networks for access the Internet is increasing. It shows that use of the main transport layer protocol TCP will be increase in near future. The traditional TCP suffer from packet losses and throughput degradation over wireless link. To improve performance of the TCP, so many variants of the TCP have been proposed like TCP Reno, New Reno, Tahoe, and Westwood etc. But no one has been deploying successfully except TCP Westwood. TCP Westwood shows improvement in throughput over Reno and SACK in wireless network. But TCP Westwood does not differentiate issue of packet loss due to congestion or bit error. So it always decrease cwnd (congestion window) in all issues of packet loss and degrade the performance. This paper proposes a novel approach to improve the performance of TCPW by differentiate issue of packet loss through either congestion or bit error. Modified TCPW uses the flag indication of TCP header for distinguish issue of congestion loss from bit error loss. This paper shows the better performance results of Modified-TCPW after comparing Modified-TCPW and traditional TCPW using network simulator NS-2.35.
Estimates near plane portions of the boundary for discrete elliptic boundary problems

We consider an elliptic difference operator together with certain boundary difference operators near a plane portion of the boundary parallel to some coordinate direction. We prove discrete analogues of known estimates in Lp and Schauder norms for elliptic boundary problems. The discrete estimates are then used to prove results about convergence near plane portions of the boundary of difference quotients of solutions uh of a discrete elliptic problem to the derivatives of the solution u of the corresponding continuous problem, when it is known that uh converges to u in the maximum norm or in a discrete L norm as h tends to zero. 0.

Organic chemical and nutrient dynamics in decomposing beech leaf litter in relation to fungal ingrowth and succession during 3-year decomposition processes in a cool temperate deciduous forest in Japan

Decomposition processes of beech leaf litter were studied over a 3-year period in a cool temperate deciduous forest in Japan. Organic chemical and nutrient dynamics, fungal biomass and succession were followed on upper (Moder) and lower (Mull) of a forest slope. Litter decomposition rates were similar between the sites. Nutrient dynamics of the decomposing litter was categorized into two types: weight changes in nitrogen and phosphorus showed two phases, the immobilization (0–21 months) and the mobilization phase (21–35 months), while those in potassium, calcium and magnesium showed only the mobilization phase. The rate of loss of organic chemical constituents was lignin < holocellulose < soluble carbohydrate < polyphenol in order. The changes in lignocellulose index (LCI), the ratio of holocellulose in lignin and holocellulose, were significantly correlated to the changes in nitrogen and phosphorus concentrations during the decomposition. During the immobilization phase, increase in total fungal biomass contributed to the immobilization of nitrogen and phosphorus. The percentage of clamp-bearing fungal biomass (biomass of the Basidiomycota) to total fungal biomass increased as the decomposition proceeded and was significantly correlated to LCI. Two species in the xylariaceous Ascomycota were dominantly isolated by the surface sterilization method from decomposing litter collected in the 11th month. The organic chemical, nitrogen and phosphorus dynamics during the decomposition were suggested to be related to the ingrowth, substrate utilization and succession of the Xylariaceae and the Basidiomycota. Twenty-one species in the other Ascomycota and the Zygomycota isolated by the washing method were classified into three groups based on their occurrence patterns: primary saprophytes, litter inhabitants and secondary sugar fungi. These species showed different responses to LCI and soluble carbohydrate concentration of the litter between the groups.
The Role of Personality Characteristics and Psychological Harassment Behaviors Which Employees Are Exposed on Work Alienation

The main purpose of the research is to address the role of psychological harassment behaviors (mobbing) to which employees are exposed and personality characteristics over work alienation. Research population was composed of the employees of Provincial Special Administration. A survey with four sections was created to measure variables and reach out the basic goals of the research. Correlation and step-wise regression analyses were performed to investigate the separate and overall effects of subdimensions of psychological harassment behaviors and personality characteristic on work alienation of employees. Correlation analysis revealed significant but weak relationships between work alienation and psychological harassment and personality characteristics. Stepwise regression analysis revealed also significant relationships between work alienation variable and assault to personality, direct negative behaviors (sub dimensions of mobbing) and openness (subdimension of personality characteristics). Each variable was introduced into the model step by step to investigate the effects of significant variables in explaining the variations in work alienation. While the explanation ratio of the first model was 13%, the last model including three variables had an explanation ratio of 24%. Keywords—Alienation, Five-Factor Personality Characteristics, Mobbing, Psychological Harassment, Work Alienation.
An Ideal Base Station Sequence for Pattern Recognition Based Handoff in Cellular Networks

The significance of having a correct criterion for evaluating handoff methods is that telecommunication providers can choose the right handoff algorithm in a cost effective way. In cellular or micro cellular environments in cities, users often move on predetermined paths. As the built environment is not changed often, this regularity can be exploited in a pattern recognition based handoff method. The most suitable sequence of assigned base stations or the Best Handoff Sequence (BHS) can provide the basis for pattern recognition based handoff methods. This paper describes in detail a computationally simple method to estimate BHS which can also be used as a benchmark for comparing different handoff algorithms. Further, it uses the recent work in Call Quality Signal Level (CQSL) evaluation to compare various well known handoff methods.
A Theoretical Investigation of Dimethyl Carbonate Synthesis on Cu-Y Zeolite

A theoretical analysis of the mechanism of dimethyl carbonate (DMC) synthesis via oxidative carbonylation of methanol on Cu-exchanged Y zeolite, Cu−Y, was explored using density functional theory. These calculations show that methanol adsorbs in the presence of oxygen to form coadsorbed methoxide and hydroxide species and dimethoxide species on extraframework Cu+ cations. DMC can form by CO addition to the former species to produce monomethyl carbonate species, which then react with additional methanol or by CO addition to dimethoxide species to form DMC directly. The turnover frequency for DMC synthesis is estimated to be 1.2 × 10-5 s-1 for the reaction conditions used in the experimental work of Zhang and Bell (J. Catal., in press). This value compares very closely with that observed, 5 × 10-5 s-1. The calculated value of the apparent activation energy is 15.0 kcal/mol, in good agreement with that measured experimentally, 14.8 kcal/mol. The effects of methanol and oxygen on the adsorption of CO have als.
Comparison between two original methods including scattering in 3D channel simulations

Two original methods to characterize the channel behavior in indoor environments composed of rough surfaces are presented and compared between themselves. They are based on algorithms developed for the image rendering field using Monte-Carlo methods to simulate the scattering phenomenon from rough surfaces. A previous study has shown which statistical parameters of real rough surfaces such as wall roughcasts have to be considered in order to have the more realistic scattering simulation as possible. Firstly, this paper presents in details the two studied methods. Secondly, we compare their performance and accuracy by simulating the radio channel for different rough indoor environments at 60 GHz
