Participation in Physical Activity and Social Media Addiction in Students

The purpose of this research was to examine participation in physical activity and social media addiction among university students. A total of 462 university students from 3 different universities voluntarily participated in the study. In the study, the “Motivation Scale for Participation in Physical Activity” and “Facebook addiction scale” were used as data collection tools. In the study, the independent sample t-test and One-way ANOVA test were applied for normally distributed data depending on the number of variables. Also, correlation analysis and regression analysis were used. According to the simple linear regression analysis conducted to determine the effect of motivation on participation in physical activity on social media addiction, it was determined that the model established was statistically significant (F=70.305; p<0.05) and the ratio of explanation of the dependent variable by the independent variable was R2=0.182. It was determined that the most important factor that motivates students to participate in physical activity is individualistic reasons. Individualistic reasons were followed by environmental and causality factors, respectively. The results of the study show that students' participation in physical activity and social media addiction was not significantly differ in terms of their gender.
INFLUENCE OF DRIFTING ON AMINO ACID PROFILES, MINERALS, PHENOLIC CONTENTS AND ANTIOXIDANT ACTIVITY OF THREE MARINE BROWN ALGAE

Effect of drifting on amino acids profile and mineral content in attached and drift marine algae: Dictyota dichotoma, Sargassum vulgare and Cystoseira spinosa (phaeophyta) was investigated as well as, their antioxidant activity in relation to their total phenolic content. All algae tested displayed similar amino acid patterns, with predominance of aspartic and glutamic acids in their tissues. Total phenolic contents varied from a minimum of 0.22 mg g -1 dw in drift Cystoseira samples, to a maximum of 0.93 mg g -1 dw in attached Dictyota samples. The results revealed that drifting negatively affect the phenol content of studied species. The extract of attached and drift D. dichotoma found to have the most potent antioxidant activity (45.38 and 33.61%), respectively. Cu and Na were presented in low values, especially in Dictyota dichotoma, while Fe and K were the most abundant elements in all algae analyzed. All micro and macro elements values were negatively affected by drifting, except those values of K, Ca and Mg in Cystoseira samples.
PROJECT BASED LEARNING TO ENHANCE CREATIVE THINKING SKILLS OF THE NON-SCIENCE STUDENTS

This study was aimed to describe students' creative thinking skills in integrated science learning on the theme of water pollution using project-based learning. The method used in this study was a descriptive method. The population and sample in this study were non-science students at a university in Bogor. The instruments used in this study were tests of creative thinking skills, peer assessment and product creativity assessment rubrics. The results showed that the average test score of students' creative thinking skills was 89% (very good category). The achievement of peer assessment indicators is 87%, while the achievement of product creativity indicators is 88%. Thus, it can be concluded that project-based integrated science learning can be used to improve the creative thinking skills of non-science students
Responses of in vitro cultured kiwifruit shoots to treatments with green amaranth aqueous extracts

Summary Because of environmental hazards related to the use of synthetic Fe-chelates in Fe-chlorosis control of plants, and with the purpose of using plant extract treatments as an alternative strategy, the effect of Amaranthus retroflexus L extracts on Actinidia deliciosa Liang et Ferguson shoot cultures was investigated, and the possibility of using in vitro cultures for rapid evaluation of the effect of such extracts on growth and Fe-chlorosis control in fruit plants is discussed. The extract was obtained by macerating for a week 100 g plant fresh weight in 1 litre of distilled water, filter-sterilizing and adjusting the pH to 5.65; the extract was added at 0 (control), 20, 2, 0.2 and 0.02 ml to 100 ml of previously autoclavesterilized modified Murashige and Skoog, MS, medium (PM), and salt-deficient PM/3 (third MS salt strength) and rooting RM (lacking growth regulators, half MS salt strength) media. The addition of 20 ml water extract to 100 ml PM/3 strongly reduced shoot and basal callus development, while 0.02 ml per 100 ml increased both with respect to the control. Rooting was hastened with 0.02 ml extract per 100 ml RM with respect to other concentrations. Moreover, roots produced with 0.02 and 0.2 ml extract per 100 ml RM were longer than with other treatments and in the control. The addition of 0.02 ml extract per 100 ml PM/3 medium, and of 0.02 to 2 ml extract per 100 ml RM improved the photosynthetic activity of cultures after five and four weeks in the proliferation and rooting phases, respectively.

The Students’ Perception on Teachers' Teaching Style at SMAN 03 Banda Aceh

The study was conducted to investigate senior high school students’ perceptions of their teachers’ teaching styles and impact of teacher teaching style on students’ motivation to learn English. This research was conducted at SMAN 03 Banda Aceh. The participants of this study were six students at second grade of SMAN 03 Banda Aceh. For collecting the data I used interview. To analyze the result of the interview, I used descriptive analysis. The findings from this study led to the following conclusions: (1) facilitator teaching style is preferred by students in SMAN 03, Banda Aceh because the teachers often give supports and ideas in decision-making and encourage the students to develop suitable criteria’s in teaching and learning process. (2) there is a strong impact between teachers’ teaching style with students’ motivation in learning English.
Multiantenna GPR data acquisition design

Detailed characterization of shallow sediments requires the use of very high frequency signals able to resolve fine changes in rock properties. For this reason Ground Penetrating Radar (GPR) has been chosen by the Matter-wave laser Interferometric Gravitation Antenna (MIGA) project to provide the information needed to apply near-surface corrections. Given the similitude of the physics of electromagnetic waves and seismic waves we used seismic modelling software to simulate GPR signals. The goal was to study two acquisition setups designed for the data acquisition. The original setup consisted of eight GPR transceivers, five of them spaced at 0.2m and the rest at 1m, for a maximum offset of 3.8m. This setup, despite providing a regular offset sampling was not able to provide the data needed for accurate velocity picking. For the second design the separation between the first and second group of transceivers was increased from 1m to 4m to provide a maximum offset of 6.8m. This setup provided better data for velocity picking, especially for deep events. However, under this configuration not all offsets could be sampled. The time images obtained confirm that a depth migration is needed to properly map the dip of the interfaces, especially in areas with significant lateral velocity changes. Performance of depth migration and inversion algorithms on the modelled GPR data remains to be explored.
Novel Roles for Acyl-Synthetases and Acyl-Thioesterases in Plant Lipid Metabolism

Acyl lipids are a diverse and important class of biomolecules. In plants, acyl lipids include ubiquitous compounds such as phospholipids, galactolipids, and triacylglycerols, as well as more specialized compounds including cutin and suberin monomers, cuticular waxes, and oxylipins. All acyl lipids are derived from fatty acids, which generally require activation for metabolism to either a CoenzymeA (CoA) or an acyl carrier protein (ACP) thioester. Acyl-synthetases and acyl-thioesterases, enzymes that activate and deactivate fatty acids, respectively, provide important checkpoints in lipid metabolism. Historically, the activation/deactivation paradigm of acyl-synthetases and acyl-thioesterases has been quite simple. However, various more sophisticated roles of these enzymes classes have been suggested, which is in line with the fact that a typical plant genome encodes many more of these enzymes than a simple activation/deactivation model would require. In this thesis I explore some of these more specialized roles of fatty acyl-synthetases and fatty acyl-thioesterases using the model plant Arabidopsis thaliana. First, I present evidence that Arabidopsis long-chain acyl-CoA synthetases LACS1, LACS2, and LACS3 are involved in trans-membrane movement of fatty acids, possibly playing a role in directing flux of fatty acids into particular biosynthetic pathways. This finding has implications in our understanding of the trafficking of ubiquitous fatty acyl-CoA substrates in plant cells, the conclusions of which can be extrapolated to other LACS proteins. Second, I characterize a novel family of Arabidopsis acyl-ACP thioesterases called ALT1, ALT2, ALT3, and ALT4. These genes were found to be expressed in various tissues throughout the plant, each with a unique expression pattern. When expressed heterologously in E. coli, each ALT protein generated a unique set of medium-chain fatty acids and/or medium-chain β-ketofatty acids. The occurrence of medium-chain fatty acids and β-ketofatty acids in various tissues of Arabidopsis plants provides clues regarding the biological roles of ALT1-4. Potential ALT homologues are found in nearly all plant genomes, and the encoded proteins are likely involved in specialized metabolism. This research opens many doors for future research, both in terms of basic research of plant lipid metabolism as well as applied uses of specialized high-value acyl lipids.
Screening and identification of tobacco mutants resistant to tobacco and cucumber mosaic viruses

SUMMARY Deploying resistant cultivars is an economical and essential management method in controlling viral diseases, and there are several mutational resources for tobacco. In the present study, the inoculation of tobacco plants with tobacco viruses was performed in a greenhouse from 2011 to 2014 to identify mutants resistant to tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV). The high-throughput screening included seeding uniformly, transplanting in seedbeds, inoculating by cloth brushes and reporting symptoms based on disease indices. A total of 4000 second generation segregating (M2) mutants of tobacco cultivar Zhongyan100 were screened. Seeds from highly resistant mutant M2 plants were selected and planted separately. The M3 were grown and mutational stability was measured. For TMV, ten highly resistant plants were selected in the M2 generation and the mutation rate was 0·012%. In the M3 generation, there were seven mutants with hereditary high resistance and, according to the results of real-time polymerase chain reaction, the N gene was detected in all seven M3. Two hereditary immune M4 mutants, one of which was a male sterile line, were identified and evaluated in the glasshouse and in the field. For CMV, seven highly resistant plants were selected from the M2 generation and the mutation rate was 0·009%. In the M3 generation, there was one mutant with hereditary high resistance. The results indicate that hereditary mutants may be identified in the M4 generation and back-crossed to wild-type Zhongyan100 to identify anti-viral genes.

Rye Chromosome Composition And Kernel Characters In Different Hexaploid Triticales

The R/D substitutions was studied through Giemsa banding and their correlations with kernel characters determined in 64 hexaptoid spring triticale strains/varieties. Karyotypic analysis revealed that 15 strains had full complement of rye chromosomes, while others had only replacements of one (in 35 strains) or two pairs of rye chromosomes. Preferential R/D substitutions were noticed with chromosome 2R being replaced in most cases, followed by 5R and 4R/7R. In none of the strains studied chromosome IR was replaced. Triticale strains with 4R/7R substitution exhibited lower degree of kernel shrivelling, with higher values for test weight, 100-kernel weight and volume of water displaced by 100-kernels. But 2R, 3R, or 5R replacements resulted in high kernel shrivelling. Any two of these substitutions present together in one triticale, had cumulative effect. The 2R/2D substitution lines exhibited higher seed set, whereas 4R/4D substitution resulted in medium seed set. The seed set was considerably high when both 2R/2D and 4R/4D occurred together. Seed set was low when 3R and 5R were substituted alone or together.
The Sclerotic Ring in North American Birds

IT is well known to students of ornithology that a number of birds, particularly such larger forms as eagles, hawks, vultures and owls, have in the sclerotic coat of the eye a supporting ring of bony plates. Less well known is the fact that such a ring is developed to a greater or less degree in the eyes of all species of birds. Even in hummingbirds sclerotic rings are found, made up of minute osseous plates of almost the thinness of tissue paper. Comparatively little attention has been devoted to these rings, although according to Lemmrich (1931), who gives a history and rather complete bibliography of the subject, knowledge of their occurrence in birds of prey dates back to the thirteenth century, and a clear description of them was given by Volcher Coiter in 1645. Students of the osteology of birds, however, have as a rule merely referred to the sclerotic ring in passing, sometimes taking casual notice of the number of plates but giving no consideration to details of shape or arrangement. Slonaker (1918, 1921) has given a careful description of the structure and embryonic development of the scleral plates in the eye of the English Sparrow. Heilmann (1927) has mentioned and figured the scleral ring in certain recent and fossil birds and reptiles. It remained for Lemmrich (loc. cit.) to point out, after examination of representatives of a considerable number of orders and families of birds, that a great deal of variation in the character of the sclerotic ring occurs in different groups, but that a degree of constancy usually prevails within given families or orders. The present study was largely completed before Lemmrich's investigations came to our attention. The findings here reported, however, are in the nature of an extension rather than a duplication of that author's work, inasmuch as he dealt largely with European birds, and in cases where American species were considered his material was rather limited. In the present investigation 1404 pairs of sclerotic rings have been examined in considerable detail, including those of 235 species involving representatives of all of the orders of North American birds except one (no specimens of trogons having come to hand). In general we have several species represented in each order and in a few cases (English Sparrow, Mallard and Glaucous-winged Gull) enough individuals of one species have been available to permit a statistical study.
The early role of the transcription factor COUP-TFI in cortical development.

The mammalian neocortex is the seat of sensory and motor processing as well as higher brain functions. Its development is regulated by patterning centers and transcription factors expressed in temporally and spatially restricted fashions. Our understanding of the functions of such transcription factors during development has been limited by the pleiotropic effects and neonatal lethality resulting from null mutations. Chicken Ovalbumin Upstream Promoter Transcription Factor I (COUP-TFI) is a transcription factor expressed in the cortex during development, which has previously been implicated in cortical development by characterization of a COUP-TFI null mutant. In this report we described the use of a conditional mutant approach, in which COUP-TFI expression is eliminated exclusively from the cortex using lox-CRE technology, to investigate the role of COUP-TFI during cortical development. We have provided preliminary evidence for a novel role of COUP-TFI as a prodifferentiation factor in early cortical neurogenesis and as a regulator of neuronal diversity during the formation of the cortical plate. COUP-TFI appears to act as a regulator of upper versus lower layer neuronal cell fate in a way that is reminiscent of the function of its fly homolog, sevenup, in regulating early versus late neuronal fate in the fly nervous system. The elimination of COUP-TFI from the cortex also allowed us to identify its role outside of the cortex in guiding thalamocortical axons through the internal capsule. These data provide exciting prospects prospects for further insights into transcriptional programs regulating cortical development.
Imaginal Diapause and Gonadal Maturation of Maniola jurtina (Lepidoptera: Satyridae) from Tuscany

IMAGINAL DIAPAUSE AND GONADAL MATURATION OF MANIOLA JURTINA (LEPIDOPTERA: SATYRIDAE) FROM TUSCANY BY VALERIO SCALI Institute of Zoology and Comparative Anatomy of the University, Pisa, Italy The interesting results obtained on genetic variation in English populations of the meadow brown butterfly, Maniolajurtina (L.) (see Ford 1964) have suggested to me the possibility of extending that work by investigating this insect in Tuscany (central Italy) where continental and insular populations of the butterfly can be compared. Data obtained on spot-frequencies will be dealt with in another paper; here I wish to present some findings on reproductive biology which have emerged as a parallel line of research during three collecting seasons (1967, 1968, and 1969).
Divergent forecasts for two salt marsh specialists in response to sea level rise

Ecosystem specialists are predicted to be more vulnerable to global change than generalists, but whether specialists within an ecosystem will respond similarly to those changes is often largely unknown. Will specialists track changes in their habitats as a group, or are their distributions governed by landscape gradients that will make some species more sensitive to habitat changes? In this study, we forecasted the effects of sea level rise (SLR) on two salt marsh specialist bird species: clapper rails Rallus crepitans and seaside sparrows Ammodramus maritimus. We sampled the abundance of these two species in salt marshes throughout the Georgia, USA, coast in 2013–2014, and analyzed count data using a Bayesian N‐mixture model. Model predictions were applied to an SLR land cover model to determine distribution shifts over 100 years. Both species distributions were most sensitive to the relative elevation gradient, with clapper rails using lower elevation marshes and seaside sparrows using higher elevation marshes. These disparities in habitat use, along with other differences according to marsh salinity and distance to forested areas, led to divergent responses to SLR. Clapper rail habitat is predicted to increase with SLR by 52%, but seaside sparrow habitat will contract by 81% by the year 2100. Seaside sparrow habitat is not predicted to decline until sometime between 2025 and 2050, at which point the decline will rapidly accelerate, indicating the importance of careful monitoring in future decades. Diverging responses to a global perturbation create a conservation planning dilemma: if specialists have opposing responses to SLR, it may be difficult to manage conservation areas that accommodate many species.
Dive times for foraging dugongs in the Northern Territory.

THERE are few published studies of dive times of dugongs (Dugong dugon). Direct observations are problematic because D. dugon are shy and difficult to observe in the wild from boats without creating observer effects. Time Depth Recorders (TDR’s) can record dive and surface times during dive behaviour, but there are no published data as yet for D. dugon using this technology. Although studies on dive times using Time Depth Recorders (TDR’s) result in larger data sets, their results are difficult to relate to particular behaviours such as foraging. This paper provides submergence and surface interval times for D. dugon obtained by direct observations in Darwin Harbour. Direct observations, although time consuming, can produce important information related to the ecology of D. dugon.
Inhibition of Listeria monocytogenes by Cocoa in a Broth Medium and Neutralization of this Effect by Casein.

Dutch-processed cocoa (0.75 to 10.0%, w/v), when added to a broth medium, inhibited/inactivated Listeria monocytogenes strain V7. With agitated incubation at 30°C, samples with 5.0, 7.5, and 10.0% cocoa were free of detectable viable cells (<1/ml) 15 to 24 h after inoculation to contain ca. 1 × 105 L. monocytogenes strain V7/ml. Without agitation at 30°C, presence of 0.75 to 10.0% cocoa lengthened (1.02 to 1.12 h) the generation time of the pathogen when compared to samples without cocoa (0.94 h). However, the pathogen, in samples containing cocoa, eventually reached a higher (9.05 to 9.18 log10 CFU/ml) population than in samples without cocoa (8.81 log10 CFU/ml). The lag phase of L. monocytogenes was longer with (8.15 h) rather than without (4.41 h) agitation, at a lower (ca 1×103 CFU/ml) (6.92 h) rather than a higher (ca. 1 × 105 CFU/ml) (5.65 h) inoculum level, and in the presence of 0.75% (10.52 h) rather than 0% (2.04 h) cocoa. Higher maximum populations (9.18 log10 CFU/ml) developed in samples that were agitated rather than incubated quiescently (8.39 log10 CFU/ml), and in samples with (9.23 log10 CFU/ml) rather than without (8.88 log10 CFU/ml) cocoa. Casein (1.5 or 3.0%) relieved the inhibition when incubation was quiescent and inactivation of L. monocytogenes by cocoa when incubation was with agitation. Without agitation, the lag phase of the pathogen was extended in the presence of cocoa (4.01 h) compared to samples with cocoa and casein (1.77 to 2.74 h). Casein did not significantly (p>0.05) affect the maximum population attained by the pathogen, but presence of cocoa increased the maximum population (8.86 and 9.25 log10 CFU/ml for 0 and 5.0% cocoa). With agitation, presence of 5.0% cocoa completely inactivated the pathogen; however, addition of 2.5% casein to these samples allowed growth of L. monocytogenes to a population of 9.47 log10 CFU/ml (compared to 8.90 log10 CFU/ml in broth).
