Molecular characterization of Iranian black cumin ( Nigella sativa L.) accessions using RAPD marker

Nigella sativa L. (2n = 12) is an annual flowering plant belonging to the family Ranunculaceae known for medicinal properties demonstrating valuable components that are widely used in food and pharmaceutical industries. Nine Random Amplified Polymorphic DNA markers (RAPD) were used in this study, in order to characterize the genetic variation of 16 black cumin varieties collected from Iran’s different regions. The amplification reaction produced 95 bands with sizes ranging from about 100 to 500 bp. The average frequency of bands was 20 while the averages of polymorphism were about 8.11 per primer. The Jaccard similarity coefficient and the Unweighted Pair-Group Method Analysis (UPGMA) clustering algorithm were applied to the RAPD data sets in order to understand the genetic relationships among the tested accessions. The accessions were categorized into three groups using cluster analysis. The results were supported by the Principal Coordinate Analysis (PCoA) cluster analysis. The results showed that the tested black cumin genotypes had a high genetic diversity and could be used in black cumin germplasm conservation programs. Moreover, the RAPD is a versatile approach to the diversity analysis of native accessions of black cumin.
Biochemical and Functional Properties of Yam Flour during the Post-harvest Conservation of Dioscorea alata Cultivar « Azaguié »

Aims: To be follow the biochemical and functional properties of yam flour during the post-harvest conservation of yam « Azaguié » ( Dioscorea alata ) tubers. Study Design: Analysis of variance (ANOVA) was carried out in this work. Place and Duration of the Study: Food Science and Technology Research from December 2014 to February 2016. Methodology: The yam tubers stored after harvest in a warehouse were kept for 6 months. Tubers were randomly taken for the preparation of flour every two months. Flours were obtained after grinding and sieving the pulp pieces and dried at 45°C for 48 h. Thereafter, the biochemical and functional analyses were performed on these different flours. Results: except for the lipid contents, all biochemical properties that were measured vary significantly ( P ≤ 0.05) with post- harvest conservation time of the yam tubers. Dry matter, total sugars and reducing sugars increased. By cons, protein, phenolic compound, ash and minerals (calcium, copper, potassium, magnesium and zinc) decreased with post- harvest conservation time of the yam species tubers. With regard to functional properties studied, water absorption capacity (WAC), oil absorption capacity (OAC) and wettability increased significantly ( P ≤ 0.05) with post-harvest conservation time of the yam tubers. However, the water absorption index (WSI), hydrophilic lipophilic index (HLI), bulk density, foaming capacity and foam stability decreased significantly ( P ≤ 0.05) during post-harvest conservation of yam tubers. Conclusion: This study shows the importance of post-harvest conservation time of the yam tubers in the use of these categories of flours in food technology.
Determination of in vitro antioxidant activity of the leaves extracts of Ehretia pubescens

The foods from plants were known to ensure against degenerative diseases and maturing because of their antioxidant activity credited to their high polyphenolic content. Information on antioxidant activity of Indian medicinal plant is abundant. To the best of our knowledge, biological properties have not been accounted in the literature for this species of Ehretia. As a point, this is the irst results to assess the anti-oxidant activity of the plant Ehretia pubescens Benth which belongs to the family Ehretiaceae. The antioxidant activity of Methanol, Hexane, Ethyl acetate and Aqueous extracts of E. Pubescens was determined using the DPPH free radical scavenging activity, ABTS radical scavenging activity and reducing power assay. The DPPH scavenging activity showed higher activity observed in methanolic extract (63%) of E.pubescens than ethylacetate (54%), hexane (44%) and aqueous (30%). Similarly the ABTS assay showed highest inhibition in methanolic extract (58%) than ethylacetate (43%), hexane (38%) and aqueous (32%) extracts. The reducing power assay of different extracts was increased in methanolic extract (54%) than ethylacetate (40%), hexane (34%) and aqueous (28%) extracts. Overall, the methanolic and ethyl acetate extract had higher antioxidant properties than other extract. However, in this study, Ehretia Pubescens Benth extracts exhibit great potential for antioxidant activity and may be useful for their nutritional and medicinal functions.

Lipofilling in Burn Scars: Our Experience

Introduction: Management of burn scars is a challenging and a complex topic. Various surgical and non-surgical options are present. Recently, a minimally invasive procedure known as autologous fat transfer is being used as an alternative technique to surgical excision for scar management. Although fat grafting may be a promising modality for scar management, there is a limited numbers of studies about their use in burn scars. Methods: We conducted an observational retrospective study for patients referred to our private clinic for the treatment of burn scars and contractures using autologous fat grafts between February 2009 and May 2018. All patients were surgical candidates for burn reconstruction. The end result was the patients’ level of satisfaction and plastic surgeons’ evaluation at 1 year. Results: 20% (n=40) were mildly satisfied with the results, 50% (n=100) were moderately satisfied, and 30% (n=60) were extremely satisfied. Only 40% of the moderately satisfied patients were willing to undergo more procedures for scar improvement. 45% (n=90) of the patients had a clinical improvement greater than 50%. J Surg Res 2020; 3 (3): 177-185 DOI: 10.26502/jsr.10020070 Journal of Surgery and Research 178 Conclusion: Lipofilling can be considered a safe, simple, minimally invasive, and autologous technique for plastic surgeons to benefit from in burn reconstruction before trying more invasive surgical procedures.
Dyckia racinae L. B. Sm. (Bromeliaceae): morphological description emphasizing the reproductive structures

This study presents an analysis of the external morphology and anatomy, especially of the micromorphology of reproductive organs that are important for characterizing Dyckia racinae L.B. Sm. The presence of a parietal U-shaped thickening in the endothecium and in the connective differ from other Dyckia species. Characteristics of pollen grains and ovules, indicated by micromorphology of the sporoderm and structure of the chalazal appendix, respectively, are similar to other species, and useful for characterizing the genus. Preferences for rocky soils, besides leaf characteristics and infl orescence structure, approximate D. racinae to D. cabrerae Smith & Reitz in the main dichotomous keys for the genus. Considering that Dyckia racinae is endemic in Rio Grande do Sul, and that the original description of the species was proposed based on a single cultivated individual, it is clear that the characteristics described in the present study, based on individual species analyzed in their natural environment, are important botanical contributions.
NUMERICAL METHOD FOR CRACK LOCALIZATION IN A CONCRETE MODEL USING ACOUSTIC EMISSION

We developed numerical method to localize crack in a concrete domain. Cracks in a domain Ω cause acoustic waves (as shown in Fig. 1)) which reach to the boundary of Ω [1]. The waves are measured at a finite number of points on ∂Ω (as shown in Fig. 1). Using the measured waves on Domain measured signal source signal Figure 1. Appearance of crack causes wave source represented as red star. We measured the wave signal at some points of the boundary of the domain, represented as blue dots. ∂Ω, the goal is to find position of cracks in Ω. Under the assumption of homogeneous medium, we consider a velocity of wave propagation is constant. With the constant velocity, we can find the position of crack by minimizing the cost function φ(x, y, t) = ∑ φi,j(x, y, t) where φi,j is discrepancy of velocity at iand j-th measurement, (x, y) is position of and t is time when crack occurs. φi,j(x, y, t) = ( (t− tj)((x− xi) + (y − yi))− (t− ti)((x− xj) + (y − yj)) )2 We compared the proposed method with the conventional time reverse modeling (TRM) method [2,3]. In TRM, the measured signals are re-emitted numerically into a domain in a time-reversed manner by solving the linear anisotropic elastic wave equation for the displacement field ui(x, t) ∈ R (d = 2 in this paper) which reads: ρg∂ttui = ∂j(cijkl∂luk) + fi in Ω× [0, T ] where fi represents wave force caused by crack, gravitational density is given by ρg and cijkl denotes the stiffness tensor, which gives the momentum tensor by mij = cijkl∂kuk [4]. To compare and verify performance in various situations, we perform several numerical experiments. Most of cases both methods are capable of localizing AE activity in concrete. However when the measurements are only on one side, TRM fails to localize crack position while suggested method is still able to localizing crack position (Fig. 2). m ea su re m en ts o n al l 4 s id es m ea su re m en ts o n le ft si de o nl y conventional TRM method suggested method source position estimated source position Figure 2. Comparison of ‘conventional TRM method’ and ‘suggested method’. Two different numerical experiments are performed; with measurements on all 4 sides and with measurements only on left side. Blue dots represent position of measurements, red circles are source positions, and green squares denote estimated source positions.

A Model for Early Detection and Avoidance of Congestion in MANET

—In a MANET, no architecture is needed to make nodes to communicate with one another. Its constant changes in network topology, as well as the wireless channel's common existence, present significant difficulties. Mobile ad hoc networks (MANETs) are entirely a mobile community by such active location & network topology structure that can be variation immediately in terms of time and application requirement. The mobile node usability factor not only opens doorfor different applications but also provides reasons for network loss. MANETs have different features that make congestion management more difficult. This paper examines a similar approach to congestion solving situations and minimizing loss of packets in wireless networks. The method of using the concept of trust aware with Queue status for bandwidth aware routingis and we have demonstrated our approach to improves system performance and reduces number of packets deposited on the network.

Ovarian and Uterine Blood Flow Indices in Patients with Unexplained Infertility Undergoing ICSI and their Relation to Clinical Pregnancy Rate

Background: Infertility is defined by the World Health Organisation (WHO) as a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse and is estimated to affect as many as 48.5 million couples worldwide. Unexplained infertility (UI) constitutes an important portion of the infertility reasons (up to 30%) and is diagnosed when the causes of male or female infertility remains unknown.Aim: The aim of the study was to compare ovarian, uterine artery and subendometrial vessels resistance by measuring PI and RI of patients diagnosed as UI undergoing ICSI in the day of embryo transfer and control group diagnosed as fertile by having at least one livebirth in peri-implantation period from day 19 to day 21.Materials and Methods:The current study is a prospective case control study, which was conducted at the Assisted Reproduction Technology unit of Ain Shams University Maternity Hospital during the period from September 2017 to July 2019. The current study included two groups of patients one group is unexplained infertility attending the Assisted Reproduction Unit and the other is control fertile group each group consists of 51 women.Results: There was statistically significant difference between the unexplained infertility group and control fertile group as regard Uterine and subendometrial artery PI, RI and ovarian artery RI in which resistance indexes was significantly higher in the UI group than control group. The cut off values of PI, RI between unexplained infertility and fertile group are ≥1.88, ≥0.8 for Uterine artery, and ≥ 0.87, ≥0.53 for subendometrial arteries, and ≥ 0.59 for ovarian artery RI. Among the unexplained infertility undergoing ICSI patients the pregnancy rate is 23.5%. There was no statistically significant difference between the two groups (pregnant group and non-pregnant group) as regard the age, BMI, duration of infertility or the basal hormonal profile.Conclusion: Doppler parameters are useful tools to assess endometrial receptivity in unexplained infertility patients undergoing ICSI. This study found that Uterine, Ovarian, subendometrial arteries plasticity index (PI) and resistance index RI measured on the day of embryo transfer higher than fertile women and have value in judging endometrial receptivity and predict the final outcome of IVF/ ICSI- ET. Uterine, ovarian and subendometrial blood flow assessed by measuring PI, RI of these arteries was impaired in unexplained infertility patients compared to fertile women. Also, uterine arteries PI, ovarian and subendometrial arteries PI, RI differ in pregnancy outcome in unexplained infertility patients undergoing ICSI.
Analysis and Design of Power Supply Circuits for RF Oscillators

This article presents guidelines for designing the power supply blocks of RF oscillators. To preserve their spectral purity, the requirements on the noise and ripple of the supply voltage are firstly evaluated based on the oscillator supply pushing factor and the oscillator Figure-of-Merit (FOM). Those specifications are then employed to design and estimate the power efficiency of an analog low-dropout regulator (LDO) and a switched-capacitor DC-DC converter. As a proof of concept, a 2:1 or 3:2 switched-capacitor DC-DC converter is implemented and directly connected to our previously published 4.9 – 5.5 GHz LC oscillator. The converter provides a 1V supply voltage with a noise ≤ 0.9nV/ $\sqrt {Hz}$ at 1MHz and does not affect the inherent phase noise of the oscillator. The ripple amplitude of the converter is 30mV while its effect is suppressed by the spur reduction block embedded in the oscillator.
Design of frequency selective surface comprising of dipoles using artificial neural network

This paper depicts the design of Frequency Selective Surface (FSS) comprising of dipoles using Artificial Neural Network (ANN). It has been observed that with the change of the dimensions and periodicity of FSS, the resonating frequency of the FSS changes. This change in resonating frequency has been studied and investigated using simulation software. The simulated data were used to train the proposed ANN models. The trained ANN models are found to predict the FSS characteristics precisely with negligible error. Compared to traditional EM simulation softwares (like ANSOFT Designer), the proposed technique using ANN models is found to significantly reduce the FSS design complexity and computational time. The FSS simulations were made using ANSOFT Designer v2 software and the neural network was designed using MATLAB software.
Automatic Text Summarization: A review

— As we move into the 21st century, with very rapid mobile communication and access to vast stores of information, we seem to be surrounded by more and more information, with less and less time or ability to digest it. The creation of the automatic summarization was really a genius human solution to solve this complicated problem. However, the application of this solution was too complex. In reality, there are many problems that need to be addressed before the promises of automatic text summarization can be fully realized. Basically, it is necessary to understand how humans summarize the text and then build the system based on that. Yet, individuals are so different in their thinking and interpretation that it is hard to create "gold-standard" summary against which output summaries will be evaluated. In this paper, we will discuss the basic concepts of this topic by giving the most relevant definitions, characterizations, types and the two different approaches of automatic text summarization: extraction and abstraction. Special attention is devoted to the extractive approach. It consists of selecting important sentences and paragraphs from the original text and concatenating them into shorter form. Broadly, the importance of sentences is decided based on statistical features of sentences. This approach avoids any efforts on deep text understanding. It is conceptually simple and easy to implement.
