Social Networks Users: Fear of Missing Out in Preservice Teachers

As mobile computing and smartphones become an integrated part of our lives, the time individuals spend on social networks has significantly increased. Moreover, a link has been established between the uncontrolled use of social networks to the development of undesirable habits and behaviors including addictions. One such behavior, namely, fear of missing out (FOMO) is of particular interest and concern especially because of the widespread use of smartphones and computers, and thereby extensive use of social networks by the younger generation. This study establishes the relationships between FOMO and various social networks in an attempt to identify the problematic use of social media in Turkey and discover variables relevant to FOMO. The main objective of the study is to examine the prevalence of FOMO in preservice teachers. A total number of 363 preservice teachers on various academic courses were employed for the purpose of this study. The design was a survey which utilized a standardized questionnaire on FOMO together with a demographic questionnaire to explore the impact of the usage of smartphones and social networks by preservice teachers. The data were analyzed using descriptive statistics, independent samples t-tests, and analysis of variance (ANOVA). The overall findings of the study showed that the spread of FOMO amongst preservice teachers is at intermediate level. Significant differences were also found between groups based on gender, age, and usage of social networks. Furthermore, data from males were indicative of higher FOMO levels than female preservice teaches and again, under 21s were found to have higher levels of FOMO compared to the other age groups. A significant relationship was reported between being online on social networks throughout the day and active use of social media over seven hours, and FOMO. Furthermore, preservice teachers using Twitter, Instagram, Swarm, or Snapchat have increased levels of FOMO. Implications are discussed within current models. Keywords: FOMO, social networks, smartphones, university students.
Consumption Patterns, Processing and Nutritional Value of Traditional Snack “ Mugdugu ” Consumed in Rural Areas of Burkina Faso

Traditional African snacks are very little known to the people. The objective of this study is to present the importance of consumption, the process and the nutritional value of a snack traditionally consumed in Burkina Faso. Consumption surveys were conducted among 250 adults in rural and urban areas Lebda and Kaya in the north center area of Burkina Faso. Production follow ups were carried out at the producers in Kaya and Lebda. Carbohydrates, lipids and proteins, iron and zinc contents were determined. Mugdugu is well known to the populations, 97% know it and have used it at least once. Nearly 46% and 20% of respondents in Lebda and Kaya consumed it at least once a week. The market is the main place of supply in the two localities. Mugudugu is consumed by all age, 1 year to more than 45 years. Mugdugu is based on millet ( Pennissetum glaucum ) and peanut ( Arachis hypogea ). The process is based on two essentials steps: roasting and grinding. The average contents of carbohydrates, lipids and proteins are respectively 61.78%, 21.67% and 14.45%. Those of iron and zinc are 11.97% and 3.97% respectively. The association of cereal and legume make Mugudugu an interesting snack of good nutritional value that must attract the attention of nutrition actors.
Extracting Facets for Queries from Search Results

: A query facet is a set of items that explains an underlying aspect of a query. To address the issue of finding query facets which are various groups of words or phrases that clarify and summarize the content covered by a query. In order to solve this problem, we propose a systematic solution refer to as QDMiner, which discovers query facets by aggregating frequent lists contained in top search results. We further analyse the issue of list duplication and discover the better query aspects can be mined by displaying fine-grained similarities among records and penalizing the copied records. And also a method for creating web wrappers to extract data records from web pages. In our approach, we depend mainly on the page related content to be independent of the HTML structure. Therefore the generated wrappers are sturdy and easier to maintain and can be adapted to similar websites to collect and integrate information.
Evaluation of nitrous oxide gaseous emissions from a partial nitritation reactor operating under different conditions

In this study, continuous measurements of nitrous oxide gaseous emissions from a lab-scale partial nitritation (PN) chemostat treating ammonium-rich (1500 mgN/L) synthetic wastewater were performed, in order to achieve a deeper knowledge about its potential environmental impact. The reactor was operated at constant hydraulic retention time (HRT, 1 d) and nitrogen loading rate (NLR, 1500 mgN/L·d), with different influent alkalinity/nitrogen molar ratios (alk/N, 1 and 1.3) and dissolved oxygen concentrations (DO, 5.0, 3.0, 2.0, 1.5 and 1.0 mgO2/L). As DO ranged between 5.0 and 1.5 mgO2/L, the partial conversion of ammonium to nitrite was successfully achieved, with a negligible production of nitrate and nitrous oxide. When alk/N was increased from 1 to 1.3 (DO was not limiting, i.e. 2 mgO2/L), the increase in ammonium-nitrogen removal rate (ANRR, from 717±17 to 945±21 mgNH4-N/L·d) and the simultaneous decrease in specific N2O-N production (from 0.33±0.01 to 0.23±0.01% of ANRR) were observed. When DO was set to 1.0 mgO2/L, partial nitritation was irreversibly compromised, and a corresponding increase in specific N2O-N production was observed (from 0.22±0.01 to 0.61±0.03% of ANRR). The results indicate a clear correlation between N2O production and autotrophic ammonium to nitrite oxidation rate.

Carbohydrates plus protein reduces oxidative stress after single bout of aerobic exercise

The aim of this study was to investigate the effect of CPA in muscle damage and oxidative stress induced by aerobic exercise. Participate in the study ten healthy young (24 ± 4 years), eutrophic (23.2 ± 1 kg/m2),VO2max = 44.9 ± 10 ml/kg/min, four women performed three aerobic exercise sessions lasting 50 minutes randomly supplemented with water (WAT), isolated carbohydrate (CHO) or carbohydrate associated with proteins and antioxidants (CPA) every 10 minutes of exercise. Blood samples were taken before, immediately and 24 hours after each exercise session for analysis markers of muscle damage creatine kinase (CK) and oxidative stress malondialdehyde (MDA). Blood glucose was measured before, during and after the exercise. After testing the data for normality and homogeneity through the Shapiro-Wilk and Levine tests, one-way ANOVA or two-way analyses were made to compare the initial and the answers to the experimental procedure respectively, or their corresponding non-parametric. CHO and CPA resulted in maintaining or increasing glucose, respectively, during exercise, whereas WAT resulted in glycemia reduction. CHO or CPA did not affect CK post exercise concentration. MDA values were very similar immediately after exercise between CHO and CPA, however occurred significant reduction from post exercice to 24 hours after exercise in CPA procedure (4.8 ± 1.8 to 2.5 ± 0.8, p <0,05), while CHO (5.1 ± 0.8 to 4.6 ± 0.9) and WAT (4.9 ± 0.9 to 5.1 ± 0.6) did not promotes the same phenomenon. This study revealed that carbohydrates associated with proteins and antioxidants have ergogenic effect by increasing blood glucose during a single bout of aerobic exercise and accelerate the restoration of oxidative stress.

Response of Explants of Calli Rice (Oryza sativa L.) Japonica cv. “Ilmi” to Gene Transformation Using Agrobacterium tumefaciens-Mediated

The AtBI-1 gene encoding the Arabidopsis thaliana Bax inhibitor was introduced into Japonica cultivars of rice (“Ilmi”) by Agrobacterium-mediated transformation, and a large number of transgenic plants were produced. The neomycin phosphotransferase II (NPTII) gene was used as a selectable marker. The activity of neomycin phosphotransferase could be successfully detected in transgenic rice calluses. Introduction of the AtBI-1 gene was also confirmed by PCR using AtBI-1 specific oligonucleotide primers in regenerated plants. Stable integration and expression of the AtbI-1 gene in plants were confirmed by GFP analysis.
Effects of salt stress on germination of some maize ( Zea mays L .) cultivars

This study was conducted to investigate the effects of salt stress on germination of six maize (Zea mays L.) cultivars (ADA-523, Bora, C-955, PR 3394, Progen 1150 and Trebbia). The degrees of salinity tolerance among these cultivars were evaluated at seed germination stage at six different salt concentrations (0, 50, 100, 150, 200 and 250 mM NaCl). The results showed that in all cultivars as the salt concentration increased, both germination percentage and germination index decreased significantly. Responses of cultivars to salt stress indicated differences. For all salt concentrations, C-955 had the highest germination percentage and germination index. Salt concentration decreased shoot and root dry weight. Bora and C-955 had the lowest reduction of shoot and root dry weight, respectively. Progen-1550 had the highest reduction of shoot and root dry weight. On the other hand, C-955 showed better results than the other cultivars in respect of salt tolerance index. The results showed that C-955 is the cultivar to be recommended for saline soils. Progen-1550 was more sensitive to salinity in this study.
The impact of quality of service parameters to the subjective and objective video quality assessment

This paper deals with the delay, delay variation – jitter, packet loss rate and bandwidth as quality of service parameters, in the form of four types of video quality degradations. The impact of defined levels of degradation on subjective impressions (given as mean opinion scores) is analyzed. ReTRiEVED video dataset with publicly available subjective scores is used in the analysis. Three full-reference measures are used for objective assessment of video quality. The degree of consistency of subjective and objective quality scores is shown through scatter plots and quantitative measures (linear correlation coefficient and correlation of the ranks). Based on the interpolation functions, quality of service parameters are mapped to subjective experience. We show that jitter is a much more destructive effect than other degradation types.
Identification of MMP9 as a novel key gene in mantle cell lymphoma based on bioinformatic analysis and design of cyclic peptides as MMP9 inhibitors based on molecular docking

Mantle cell lymphoma (MCL) is an aggressive disease. MCL is associated with poor patient prognosis and limited survival. To identify key genes and explore targeting cyclic peptide inhibitors for the treatment of MCL, we downloaded two gene expression profiles (GSE32018 and GSE9327) from the Gene Expression Omnibus (GEO) database. We screened 84 differentially expressed genes (DEGs). Pathway analysis showed that DEMs were mainly enriched in the ‘Pathway in cancer’, ‘PI3K-Akt signaling pathway’, ‘Cytokine-cytokine receptor interaction’, ‘Rap1 signaling pathway’, ‘NF-κB signaling pathway’ and ‘Leukocyte trans-endothelial migration’. We subsequently constructed a protein-protein interaction (PPI) network of DEGs. In addition, matrix metalloproteinase 9 (MMP9) with a high degree in the PPI network was identified as a hub gene in MCL. Meanwhile in the Molecular Complex Detection (MCODE) analysis, MMP9 was located in the important cluster. Thus, MMP9 can be used as a therapeutic target for MCL and we designed cyclic peptides as MMP9 inhibitors. MMP9 protein structure was gathered from the Protein Data Bank (PDB), with a PDB ID: 1L6J. MMP9 and cyclic peptides were docked using Molecular Operating Environment (MOE) software after structural optimization. It was revealed that cyclic peptide 2 bound deeply in the binding pocket of MMP9 and had interaction with the active-site Zn2+ ion in the catalytic domain. Cyclic peptides 1, 2, 4–6 also displayed potential interaction with active residues of MMP9; thus, these cyclic peptides can serve as potential drug candidates to block MMP9 activity and future studies are warranted to confirm their efficacy.
Investigating Differential Expression of MicroRNAs Related to Recurrence in the Luminal Breast Cancer Subtype

Breast cancer is a heterogeneous disease, and patients with the luminal subtype have a range of outcomes unable to be predicted by current clinical methods. My hypothesis was that microRNA (miRNA) expression profiling might provide a method of discriminating tumours of this subtype into good and poor prognosis groups, and reveal miRNAs involved in recurrence. Expression profiling revealed nine miRNAs significantly differentially expressed in luminal tumours from patients with recurrence compared to patients without recurrence. Four, miR-135a5p, miR-140-5p, miR-218-5p, and miR-200a-3p, selected for technical validation were confirmed as differentially expressed. Functional analysis in an in vitro breast cancer model revealed a reduction in cellular migration when miR-218-5p was ectopically overexpressed in two different assays, suggesting a possible association of miR-218-5p with metastasis, an important factor in recurrence. The expression of these miRNAs may allow improved prognostication in luminal tumours, and provide avenues of further research in breast cancer
A Novel Approach to Detect Jamming Attack by means of Game Theory

---By considering a scenario where a complicated jammer continuously jams the network in a single channel WSN. Generally a jammer can control the possibility of jamming and message transfer range to cause maximum harm to the network termed as despoiled communication links. The jammer action halt when jammer node can be detected by monitoring node in the network, and warning message is transmit out of jamming region. Likewise the network also know the possibility of jammer . We focus the cases of perfect awareness by jammer and the network in order to study the strategy of one another . Also consider the cases where jammer network lack this information. We also consider different energy parameters of jammer and network. Two problem can be take into account as static jamming and dynamic jamming.
The first record of the marbled crayfish adds further threats to fresh waters in Italy

* Corresponding author Received 9 February 2009; accepted in revised form 30 March 2009; published online 24 April 2009 Abstract The red swamp crayfish, Procambarus clarkii, is the most abundant invasive crustacean decapod in Italy. Evidence is however emerging for the presence of other Cambaridae that are erroneously assigned to the P. clarkii taxon. The marbled crayfish, belonging to a still uncertain species of the genus Procambarus, has been found for the first time in Italy in the Canale Maestro della Chiana (Tuscany, Central Italy), where it lives in sympatry with a large P. clarkii population. Although a single specimen was found, this record is particularly relevant due to the parthenogenetic reproductive habit of the marbled crayfish. However, molecular analyses based on COI barcoding did not reveal any differentiation within the P. clarkii population and excluded any form of hybridization between the two species. We will shortly discuss new pathways of invasive species and the threats posed by parthenogenetic species, even though they seem to be still sporadic.
Pixel-wise Hybrid Image Registration on Wood

The detection of differences between images of a printed reference and a reprinted wood decor often requires an initial image registration step. Depending on the digitalization method, the reprint will be displaced and rotated with respect to the reference. The aim of registration is to match the images as precisely as possible. In our approach, images are first matched globally by extracting feature points from both images and finding corresponding point pairs using the RANSAC algorithm. From these correspondences, we compute a global projective transformation between both images. In order to get a pixelwise registration, we train a learning machine on the point correspondences found by RANSAC. The learning algorithm (in our case Gaussian process regression) is used to nonlinearly interpolate between the feature points which results in a high precision mage registration method on wood decors.
Si-core photonic crystal fiber transverse-electric pass polarizer

Photonic crystal fibers (PCFs) have been extensively used in literature for designing polarization handling devices. Further, the Si material has advantages in terms of low loss transmission with a high refractive index. In this paper, a novel design of transverse-electric (TE) pass polarizer based on Si-core photonic crystal fiber (SC-PCF) is reported and studied using full vectorial finite element method. The suggested PCF has a SiO2 cladding background and is selectively filled with gold nanorods. Further, an elliptical Si-core is used to increase the birefringence between the two polarizing modes. Therefore, the surface plasmon modes around the gold nanorods are highly coupled with the quasi-transverse-magnetic (TM) core modes while no coupling occurs with the quasi-TE core mode. Consequently, high and low confinement losses are achieved for the quasi-TM and quasi-TE core modes, respectively. Accordingly, a TE-pass polarizer is realized with an insertion loss of −0.000108 dB. Additionally, a good extinction ratio of −13.18 dB is obtained at a short device length of 29 μm.
A SURVEY OF CONSTRUCTION PROJECT COST AND TIME CONTROL PRACTICES IN THE UK

Control is important for the successful delivery of projects. The way cost and time of construction projects are controlled differ from one organisation to another because there are numerous project control techniques in existence. However, there is limited current research surrounding the usage of these techniques by firms. To address this, a questionnaire survey was conducted in the UK aimed at identifying common project control practices in the country. Data was collected through administration of questionnaires to the top 150 construction companies (contractors) by company turnover and the top 100 construction consultancies (consultants) in the UK by the number of professional staff employed and total fee earnings. In total, 250 questionnaires were distributed with a response rate of 44%. The data was analysed using descriptive statistics and Z-test of significance. From the analysis of results Gantt bar chart was revealed as the main planning technique, project cost value reconciliation was revealed as the most commonly used cost control technique. It was also found that more than 90% of respondents frequently or always apply time and cost controls to their projects. The study found that there is no significant difference in project control practices between contractors and consultants in the UK.
Energy Conservative Opportunistic Routing(ECOR) in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are large collection of sensing nodes with processing and communication capabilities. The major issue in sensor network is limited battery power. Batteries cannot be recharged or replaced once deployed. Research on wireless sensor network has recently received much attention as they offer an advantage of monitoring various kinds of environment by sensing physical phenomenon. Recently Opportunistic Routing has emerged as a novel routing scheme that effectively improves the capacity of a multi hop wireless sensor networks. It takes the advantage of broadcast nature of wireless communication. In contrast to traditional unicast routing, where the next hop forwarder is formed before the transmission of data. Opportunistic Routing chooses its forwarder list dynamically with poor energy management. The performance of Opportunistic Routing is enhanced with energy conservation algorithms and higher throughput and thus network lifetime is increased.
The Perception of Fairness of Performance Appraisals

The perception of fairness in performance appraisals (PA) is one of the most important factors and considered a criterion when reviewing PA effectiveness (Jacobs, Kafry, and Zedeck, 1980). In this particular study, I examined numerous variables in three main categories: interpersonal, procedural, and outcome fairness. Keep in mind that although these are three distinct categories, they are all inter-related. One hundred ninety-two employees, from the research and development section of a large retail company, voluntarily participated. The results were slightly contradictory to what was expected yet they were good results. The interpersonal variable, manager effectiveness, along with the outcome variables, fair pay and rewards, and an employee’s last year’s performance rating are the strongest predictors of the perception of fairness. However, there was not a significant finding in age discrimination.
Chapter 6 Stress Induced Changes in the Raman Spectrum of Carbon Nanostructures and their Composites

Raman spectroscopy of Carbon nanostructures is fundamental in characterising the morphology and the interaction of the nanostructure with the environment. This work provides an outline of the Raman Vibrational modes for graphitic structures starting from graphite fibres, to single-wall carbon nanotubes to multiwall carbon nanotubes and finally to Singleand Multilayer Graphene. Following a brief outline of the dependence of the force constant on applied deformation, the stress induced changes in the Raman spectrum of graphitic structures are subsequently discussed with a view to elucidating the reinforcing ability of the CNTs in a matrix and assess ing the stress transfer at the CNT matrix interface. The possibilities of employing CNTs as stress sensors in composite materials are also presented.
