IN VITRO CONSERVATION OF THE UNIQUE DILLENIA INDICA GROWN IN EGYPT UNDER MINIMAL-GROWTH CONDITIONS

Dillnia indica is a very important medicinal unique tree grown in Egypt (a good source of betulenic acid). An experiment has been conducted to establish a safe protocol for minimal growth conservation using osmosis and growth retardants. Data revealed that abscisic acid (as retardant) (ABA) at 1, 2 or 3 mg/L can be able to save plant life at percentages of 66.67, 83.33 and 50, respectively up to nine months without subculturing. On the other hand, sorbitol (an osmotic substance) has a bad effect especially at high concentrations (6 and 9%) which is lead to 100% death after six months. The results show that the survived shootlets exhibited regeneration ability significantly differed after subculturing into fresh medium. At the end of conservation period (9 months), the regeneration ability of explants derived from shootlets conserved on medium augmented with 1.0 or 2.0 mg/L ABA recorded 100%. When the dendogram was constructed based on the obtained band patterns, results revealed that both the negative (mother plant) and positive controls ( in vitro propagated plants) were grouped in separate cluster. Whenever, samples treated with abscisic acid at 1.0 and 3.0 mg/l are grouped in one cluster, which indicated that they are much closed to each other and ABA is genetically safe.
Social presence of an affiliate marketer in an online product photo, consumer’s clickthroughs and sales

Summary: The goal of this article is to answer the question: what actions in the area of communicating online social presence increase the consumer’s clickthroughs and online sales of the promoted offer in the affiliate marketing context. Six cases that concern visual communication of social presence, consumer’s clickthroughs and sales have been analysed in the study. A replicable relationship between visually communicating social presence on a Facebook fan page and on the affiliate’s blog, consumers’ clickthroughs and sales value have been identified. Managerial implications of the research results are that affiliates should communicate: 1) product in use, 2) photo made by the affiliate, and expect a positive impact on both clickthroughs in the tracking link and sales. New knowledge from this study is the identified impact of social presence in visual communication on sales, while the authors of earlier studies checked the impact of social presence only on trust, purchase intent or likes, comments and conversion online.
A Genetic Algorithm for Economic Order Quantity with a Short Product Life Cycle

Considering a finite time horizon crossing over multiple stages of a product life cycle, this study presents a genetic algorithm to deal with an economic order quantity model with multiple demand rates under a non-periodic policy. In real, the demand of the product life cycle is a non-linear function but we assumes it as four-segment linear or constant approximations in this work. In addition, a multiple-segment to be combined with linear or constant functions can be approximated a nonlinear function. This study does not focus on this, but it provides a genetic algorithm to deal with this proposed inventory problems. The particular of this research is that we develop a proposed replenishment scheme by the differentiating equation of the total cost with respect to replenishment time. Then, calculate the total cost of the proposed scheme as the fitness function to evaluate the populations. In this paper, an explicit procedure to obtain an approximating solution is provided and numerical examples to illustrate the proposed model are shown as well.
H∞ Filtering for two-dimensional discrete switched systems in the second Fornasini and Marchesini model

This paper is concerned with the H∞ filtering problem for two-dimensional (2-D) discrete switched systems described by the second Fornasini and Marchesini (FM) model. The main purpose is to design a switched filter such that the resulting filtering error system under the arbitrary switching signal is asymptotically stable with a guaranteed H∞ performance level. By using the switched Lyapunov functions, a new sufficient condition is obtained to guarantee the asymptotic stability with a H∞ performance index for the filtering error system. Based on this condition, the full- and reduced-order H∞ filter design conditions are derived and formulated in terms of linear matrix inequalities (LMIs). Two illustrative examples are utilized to show the effectiveness and less conservativeness of the proposed method.
Population Distributions of Age Groups and Their Influencing Factors Based on Mobile Phone Location Data: A Case Study of Beijing, China

The fine-grained population distributions of different age groups are crucial for urban planning applications. With the development of information and communication technology (ICT), detailed population data retrieved from various big data sources, especially on a fine scale, have been extensively used for urban planning. However, studies estimating the detailed population distributions of different age groups are still lacking. This study constructs a framework to generate fine-grained population data for different age groups and explores the influence of various factors on the distributions of different age groups. The population is divided into the following four age groups: (1) early adulthood people: 18 ≤ age ≤ 24, (2) young people: 25 ≤ age ≤ 39, (3) middle-aged people: 40 ≤ age ≤ 59, and (4) elderly people: 60 ≤ age. The results indicate that education and accommodation factors have a major influence on the distributions of early adulthood and elderly people, respectively. Business, restaurant, and accommodation factors are the main factors influencing the population distributions of young and middle-aged people. The accommodation factor plays a major controlling role at night, and its explanatory power gradually decreases during the day, while the explanatory powers of the business and restaurant factors increase and become leading factors during the day. Specifically, the hospital factor has a greater effect on the distribution of elderly people. The entertainment factor has very little explanatory power for the population distributions of the different age groups.
Laying claims on the city: young Mapuche ethnic identity and the use of urban space in Santiago, Chile

ABSTRACT This article explores indigenous young people’s use of different types of space within Santiago’s unequally distributed opportunity structure to express cultural belonging and sense of place. Drawing on qualitative work informed by environmental psychology and critical geography, the article discusses how young Mapuche residents in Santiago elaborate practices and relations with their neighborhood, public areas and institutional space to establish ethnic identity. Although existing literature has demonstrated that non-essentialized indigenous identities and connections to land-territory are prevalent in urban spaces, attention has not been given to how these senses of belonging are situationally defined and negotiated across the city. We argue that place attachment and place identity are developed differentially and ambivalently within these contexts. That is, Mapuche indigenous youth and their households must navigate tensions between state-led action and personal agency, between politicized and quotidian identities, between “there” and “here,” and between past and present, so as to produce meaningful connections, activities, and affective relations according to distinct spatial dynamics and power relations.
Entrepreneurial Behavior and Intentions among Bumiputera's Students

Objective - Unemployment and marketability among graduates are the country's current issues. This became clear when the unemployment percentage among graduates continued to increase yearly. Therefore, entrepreneurship education has been chosen as an alternative solution. However, currently, student involvement in entrepreneurship is still low. As low involvement occurs among students, especially those in private colleges, students may lack entrepreneurial behavior and intentions. Therefore, this study aims to identify the level of the entrepreneurial behavior and intentions among Bumiputra's students studying in Kuala Lumpur's private colleges.Methodology/Technique - A total of 387 students participated in a quantitative survey. Using a questionnaire as the study's research instrument, the data were analyzed using SPSS version 22.0. Finding - The findings showed that the entrepreneurial behavior and intentions among students are at a moderate level. Pearson correlation coefficients indicated a significantly positive, although moderate, relationship between entrepreneurial behavior and entrepreneurial intentions. The result suggests that to increase the number of entrepreneurs among students in Malaysia, all stakeholders should be involved in inculcating an entrepreneurial culture.Novelty - An innovative and practical-based entrepreneurship curriculum should be developed to encourage students to choose entrepreneurship as a career option upon graduation.Type of Paper - Empirical.
Context guided retrieval of math formulae from scientific documents

Abstract With increasing popularity of math formula search, a number of Math Information Retrieval (MIR) systems have come into being. Characterized by either conventional text-based techniques or newly evolved formula–centric indexing and search techniques, majority of such MIR systems exhibit applaudable performance. Nonetheless, it is common to observe certain limitations of existing MIR systems. For example, context guided retrieval of math formula, whereby formula can be retrieved given its context, is less researched. To this end, this paper discusses implementation of an MIR system, which employs pattern– based discovery to extract context–formula pairs, creates a Knowledge Base (KB) of such pairs, creates an inverted index for the contexts inside KB, and eventually coordinates with index and KB to retrieve relevant formula search results for a text query. Obtained search results and values of evaluation parameters reflect promising performance and competence of the approach.
Effect of Renal Artery Stenting on Blood Pressure, Glomerular Filtration Rate and Left Ventricular Mass in Hypertensive Patients with Severe Atherosclerotic Renal Artery Stenosis

Background: Many small trials showed a significant improvement in blood pressure following renal artery stenting in patients with severe atherosclerotic renal artery stenosis, but data on renal function improvement is more conflicting. Recently, few trials have been conducted to evaluate the effect of this procedure on Left Ventricular Mass (LVM) and Left Ventricular Mass Index (LVMI). Objectives: The aim of this study is to determine the effect of renal artery stenting on Blood Pressure, estimated Glomerular Filtration Rate (eGFR), Left Ventricular Mass (LVM), and Left Ventricular Mass Index (LVMI) in patients with severe atherosclerotic renal artery stenosis. Methods: This is a prospective interventional study performed on forty patients with ischemic heart disease and medication resistant hypertension, who had severe (≥ 70%) atherosclerotic renal artery stenosis and underwent renal artery stenting. Blood pressure, LVM, LVMI and eFGR before renal artery stenting and after six months were assessed in these patients. Results: There were significant reduction in systolic blood pressure (from 175.50± 17.28 mmHg to 137.30± 13.21 mmHg) (P < 0.001), and diastolic blood pressure (from 103.45 ± 8.91 mmHg to 84.30 ± 7.33 mmHg) (P < 0.001). Also, there were significant decrease in LVM (from 307.73 ± 108.13 g to 259.34 ± 92.17 g) (P = 0.004) and LVMI (from 174.70 ± 58.26 to 148.01 ± 49.77) (P = 0.004). LVM reduction was independent of SBP and DBP reduction (P = 0.376 and P = 0.196, respectively). Conclusions: Renal artery stenting reduces Blood pressure and leads to regression of LVM independent of blood pressure reduction. Regardless of baseline eGFR, our study failed to find a significant increase in glomerular filtration rate.
BTF3-Promoter Based Screening of Anti- Human Breast Cancer Compounds

Basic Transcription Factor 3 (BTF3) is a Transcription factor known to differentially express in different forms of cancer; where in gastric cancer, silencing of BTF3 induced apoptosis. Previously, we reported Human β casein fragment 54-59 (NS) down modulates BTF3 expression in Human THP-1 cells. In the present study, we developed an in vitro model targeting BTF3 Promoter for screening of compounds down regulating BTF3 and to study the impact of BTF3 down regulation on apoptosis in MCF-7 cell line. We further confirmed the efficacy of NS to down regulate BTF3 in MCF-7 cells through western blotting. NS and its analogs AN1, AN2 and AN3 were screened on BTF3 promoterreporter construct during transient transfection in MCF-7 cell line, where the expression of reporter was found to be down regulated upon treatment. This study was further confirmed by immunoblotting which produced similar results in MCF-7 cells. To determine the biological function on suppressing BTF3 expression by NS and analogs, cell viability assay and Annexin-V-FITC staining were performed, the results clearly demonstrated an increase in apoptosis on BTF3 down regulation in MCF-7 cells. In conclusion, BTF3 expression is a crucial biomarker in breast cancer therapy and our model can be an asset for fast screening of compounds modulating BTF3 expression in different cancer forms, where it is found to be overexpressed.
Joint OAM Multiplexing and OFDM in Sparse Multipath Environments

The emerging orbital angular momentum (OAM) based wireless communication is expected to be a high spectrum-efficiency communication paradigm to solve the growing transmission data rate and limited bandwidth problem. Academic researchers mainly concentrate on the OAM-based line-of-sight (LoS) communications. However, there exist some surroundings around the transceiver in most practical wireless communication scenarios, thus forming multipath transmission. In this paper, a hybrid orthogonal division multiplexing (HODM) scheme by using OAM multiplexing and orthogonal frequency division multiplexing (OFDM) in conjunction is proposed to achieve high-capacity wireless communications in sparse multipath environments, where the scatterers are sparse. We first build the OAM-based wireless channel in a LoS path and several reflection paths combined sparse multipath environments. We concentrate on less than or equal to three-time reflection paths because of the severe energy attenuation. The phase difference among the channel amplitude gains of the LoS and reflection paths, which is caused by the reflection paths, makes it difficult to decompose the OAM signals. We propose the phase difference compensation to handle this problem and then calculate the corresponding capacity in radio vortex wireless communications. Numerical results illustrate that the capacity of wireless communications by using our proposed HODM scheme can be drastically increased in sparse multipath environments.
Efficacious Effect of Cannabis Sativa (Indian Hemp) on Cutaneous Wound Healing and its Haemostatic and Chemical Profile in Adult Male Albino Wistar Rat

Plants and plant extracts have been found very useful for purposes of treatment of disease among other benefits. Cannabis sativa is one of such plants whose effect on wound healing, haemostatic and biochemical profile was studied using albino wistar rats. Canabis sativa is an illicit drug with proven anti-inflammatory, analgesic and anti-diarrhea activities. This present study is aimed at ascertaining the impact of prolonged administration of cannabis sativa on haemostatic mechanism, cutaneous wound healing and biochemical profile of albino wistar rats. Forty (40) albino wistar rats weighing 180-200g were acclimatized in the animal house for 7 days. After this, they were divided into five groups respectively. Group A was the control male rats (6), Group B was the female control rats (6), Group C (10) was the male test rats and Group D (10) was the femaletest rats and Group E (8) for incision. Group C and D male rats were fed for 30 days with aqueous extract of Canabis sativa before 5.0ml of blood sample was collected from the animals for cardiac puncture and placed in haemogram bottles (EDTA and sodium citrate) for haemostatic analysis and in plain bottles for liver function tests while Group E rats were those with incision made in their skin that received topical treatment of aqueous extract of cannabis sativa and injection for 5days. Results from the study showed that the extract significantly increased the total and conjugated bilirubin, (P<0.05), liver enzymes; Alkaline Phosphatase (ALP), Aspartate Transaminase (AST) and Alanine Transaminase (ALT), Haemoglobin concentrations, Packed cell volume, platelet count and white blood cell count. The bleeding and clotting times,ProthrombintimeandPartialthromboplastin times were shortened compared to their corresponding controls. The incised wounds haled within shorter days than those in control rats. The alterations in the results are manifestation of mild hepatorenal toxicity and anti-hypercholestrolemic effect. These liver enzymes are highly affected by cannabis sativa in females than in males.
“My Teacher Doesn’t Like Me”: Perceptions of Teacher Discrimination and School Discipline among African-American and Caribbean Black Adolescent Girls

This study examined the impact of perceived teacher discrimination on the school discipline of African-American and Caribbean Black adolescent girls. The findings are drawn from a nationally representative sample of (n = 410) African-American and (n = 193) Caribbean Black adolescent girls age 13 to 17 (Mage = 15). Results indicate that perceiving discrimination from teachers was associated with higher school discipline (e.g., suspension, expulsion, and spending time in a jail, detention center) for African-American girls. For Caribbean Black girls, higher household income and school bonding was associated with lower school discipline. Older Caribbean Black girls were also more likely to receive higher school discipline. However, perceiving discrimination from teachers was not associated with school discipline for Caribbean Black girls. The developmental significance and implications for future research are discussed.
Dating the origin and diversification of Pan-Chelidae (Testudines, Pleurodira) under multiple molecular clock approaches

Pan-Chelidae (Testudines, Pleurodira) is a group of side-necked turtles with a currently disjointed distribution in South America and Australasia and characterized by two morphotypes: the long-necked and the short-necked chelids. Both geographic groups include both morphotypes, but different phylogenetic signals are obtained from morphological and molecular data, suggesting the monophyly of the long-necked chelids or the independent evolution of this trait in both groups. In this paper, we addressed this conflict by compiling and editing available molecular and morphological data for Pan-Chelidae, and performing phylogenetic and dating analyses over the individual and the combined datasets. Our total-evidence phylogenetic analysis recovered the clade Chelidae as monophyletic and as sister group of a clade of South American extinct chelids; furthermore Chelidae retained inside the classical molecular structure with the addition of extinct taxa in both the Australasian and the South American clades. Our dating results suggest a Middle Jurassic origin for the total clade Pan-Chelidae, an Early Cretaceous origin for Chelidae, a Late Cretaceous basal diversification of both geographic clades with the emergence of long-necked lineages, and an Eocene diversification at genera level, with the emergence of some species before the final breakup of Southern Gondwana and the remaining species after this event.
Early development of the centipede Geophilus serbicus (Chilopoda: Geophilomorpha: Geophilidae) from the Balkan Peninsula

ABSTRACT The first detailed description of early development of the recently described European geophilid Geophilus serbicus is presented. Based on specimens from a natural population from the Balkan Peninsula, new insight was gained into the reproductive and developmental biology of the group. Changes in the morphology of brooded specimens allow 15 early developmental stages obligatorily dependent on prolonged maternal care, arranged in three phases (embryonic, embryoid, and adolescent) to be distinguished. The embryonic phase includes eight stages, followed by an intermediate stage of hatching, followed in turn by five embryoid stages and one adolescens stage. Detailed morphological descriptions of all stages are provided. Adolescens I is recognized as the first stage at which species and sex identification are possible. Besides the description of the earliest stages, we provide notes on reproductive behaviour and ecological features of the species.
Perceptual Functions of Auditory Neural Oscillation Entrainment

Humans must process fleeting auditory information in real time, such as speech and music. The amplitude modulation of the acoustic waveforms of speech and music is rhythmically organized in time, following, for example, the beats of music or the syllables of speech, and this property enables temporal prediction and proactive perceptual optimization. At the neural level, external rhythmic sensory input entrains internal neural oscillatory activities, including low-frequency (e.g., delta, 1-4 Hz) phase, high-frequency (e.g., beta, 15-25 Hz) power, and their phase-amplitude coupling. These neural entrainment activities represent internal temporal prediction and proactive perceptual optimization. The present thesis investigated two critical but previously unsolved questions. First, do these multiple entrainment mechanisms for tracking auditory rhythm have distinct but coordinated perceptual functions? Second, does regularity in the temporal (when) domain associate with prediction and perception in the orthogonal spectral (what) domain of audition? This thesis addressed these topics by combining electroencephalography (EEG), psychophysics, and statistical modeling approaches. Chapter II shows that beta power entrainment reflects both rhythmic temporal prediction (when events are expected) and violation of spectral information prediction (what events are expected). Chapter III further demonstrates that degree of beta power entrainment prior to a pitch change reflects how well an upcoming pitch change will be predicted. Chapter IV reveals that rhythmic organization of sensory input proactively facilitates pitch perception. Trial-by-trial behavioural-neural associations suggested that delta phase entrainment reflects temporal expectation, beta power entrainment reflects temporal attention, and their phaseamplitude coupling reflects the alignment of these two perceptual mechanisms and is associated with auditory-motor communication. Together, this thesis advanced our understanding of how neural entrainment mechanisms relate to perceptual functions for tracking auditory events in time, which are essential for perceiving speech and music.
