Exteroceptive influences on total mood disturbance and perceived stress during green exercise

Exercise in a natural environment, termed green exercise, has repeatedly been shown through empirical research to be beneficial for psychological health. However, very little is known about the underlying cognitive mechanisms responsible for these benefits. Literature suggests that it may be an innate human connectedness to nature, and that natural environments do not require directed attention and therefore promote restoration. As the senses are used to interact with nature, this thesis set out to explore the relative contribution of sight, sound and smell to the green exercise effect. Chapter 2 found that, when presented with a choice of nature and urban images simultaneously, that participants preferred to view nature, particularly as exercise intensity increased. However, the images were not completely immersive for the participant. Therefore, a green lab was developed, described in Chapter 3, to enable the exploration of the senses of sight, sound and smell in relation to green exercise and psychological recovery. Results in Chapter 4 showed occlusion of sound had the largest detrimental effect on total mood disturbance, with smell and sight having little effect. Chapter 5 repeated Chapter 4 but addressed limitations with a modified protocol with sound removed (rather than occluded) and still reduced mood significantly. In Chapter 6, psychological stress was used to disturb mood prior to exposure to different sensory aspects of green exercise and the recovery after the stressor was explored. Results indicated that exercise with nature sounds, nature visual or exercise with both nature sounds and visual are better for recovery from an acute stressor than rest or exercise alone. Evidence provided in this thesis, highlights the contribution of the senses of sight and sound to green exercise psychological effects and the benefits of green exercise in recovery from acute psychological stress.
Lifestyle and Physical Activities among Ibans Students’ Co-Curricular Activities in Bintulu, Sarawak

The lifestyle and pattern of physical activities at school play a role to ensure students being active. This study was conducted to identify the lifestyle and pattern of physical activities in school cocurricular activities in Bintulu. The design of this study is a cross-sectional study. The sample of this study was 284 students. This study used lifestyle and school co-curricular activities questionnaire. The findings show that 131 Ibans, 52 Melanaus, 38 Malays, 33 Chinese and 30 other ethnic groups. Overall, Iban’s student's lifestyle is inactive. The related lifestyle regarding their transportation to school, where Iban students using a car which is M=2.27. Nutrition habits indicate that students have a high appetite before eating (M=1.91), students love to find extra food to increase their appetite (M=1.83) and ready to control food intake (M=1.93). The attitude showed that students confident that exercise gives benefit and positive impact on health (M=1.30) and influenced body weight (M=1.39). The pattern of physical activities showed that they are active during the PJK class (M=1.81). Physical activities in co-curricular events showed that Iban students are categorized as inactive in sports (M=1.64), uniform bodies (M=1.66) and club and society (M=1.64) and also the pattern of physical activities are exhausted (M=2.27). The student is categorized as having normal BMI (M=2.35) and have a low health risk. Lifestyle among students should in positive trend to reduce the disease risk and physical activities pattern should be systematic to build up balanced students in terms of intellectual, emotional and health.
The relationship between heterosis and genetic distances based on RAPD and AFLP markers in carrot

With 6 tables Abstract The aim of this study was to estimate the correlation between heterosis in carrot hybrids and the genetic distances of their parents. The experimental material consisted of 15 inbred lines and 34 hybrids. The yield traits (total and marketable yield), as well as quality characters (carotenes, dry matter, total sugar, monosaccharides and nitrates), were evaluated. Heterosis was computed using two measurements of mid- and high-parent heterosis. Genetic distances among lines were calculated using the RAPD and AFLP techniques. Significant heterosis was found for both total and marketable yield. The content of quality compounds for hybrids usually had mid-parent values. Significant correlations were found between molecular distances among lines, measured using RAPD markers, and heterosis of crosses for total yield, and among divergences of parents measured using AFLP markers and heterosis for marketable yield. This appears to contribute towards the carrot hybrid yield prediction by estimation of the genetic distances between parents. This research was undertaken because the possibility of heterosis prediction would allow for the reduction of costs and quicker identification of superior carrot hybrids.
A dragonfly (δ2H) isoscape for North America: a new tool for determining natal origins of migratory aquatic emergent insects

1. Tracking insect migration at continental scales is intractable using exogenous markers because of tiny body size and high improbability of recapture. Naturally occurring endogenous isotopic markers, such as tissue δ2H and δ18O, are a means of assigning origins to both vertebrate and invertebrate populations, but the success depends upon derivation of a robust algorithm linking measured tissue isotope values with large‐scale geospatial isotopic patterns (isoscapes) in the terrestrial hydrosphere.
Portable Chemical Sensors for Monitoring Infection-Specific Volatiles in Asymptomatic Citrus

Volatile organic compounds (VOCs) are emitted from all plants, and there is mounting evidence these VOCs reflect internal health status and change in response to pathogen infection and other cues. Our group has developed a portable chemical sensing platform that can monitor for VOC emission changes that result from citrus bacterial and viral infections. To date, our VOC library includes putative signal fingerprints for Huanglongbing (HLB), citrus tristeza virus (CTV) and citrus variegated chlorosis (CVC). Our mobile platform is robust and capable of operating in field conditions. We have also developed customized data analysis methods to compare data from unknown samples to our database and to determine the probability of infection for a newly sampled tree.
The Impact of Crude Oil, Natural Gas and Liquefied Natural Gas (LNG) Prices on Malaysia GDP: Empirical Evidence using ARDL bound Testing Approach

This paper attempted to investigate the impact of real crude oil, natural gas and liquefied natural gas (LNG) prices on Malaysia’ Gross Domestic Product (GDP). Empirical analysis was based on the Autoregressive Distributed Lag (ARDL) estimates over a period of 30 years, from 1987 to 2017. The results revealed that the longand short-run dynamics of GDP depended on the selected energy prices, given their dominant effects to Malaysia’s economic growth. This paper will help policymakers to address the current focus on creating the right applications that can substitute for high dependency on crude oil. Meanwhile, higher consumption of natural gas and liquefied natural gas in industrial sectors and the use of cleaner energy sources other than non-renewable energies may have provided the motivation to create this paper.
The Effectiveness of Nadas Career Counseling Model towards Career Maturity and Self-Concept of Former Drug Addicts: A Qualitative Study

Chronic unemployment is seen to be one of the most contributing factors of relapse among drug addicts in Malaysia. Many interventions had been implemented by the government to helps the client with fully abstinent. However, the number of drug addicts can’t be deemed to be reduced especially for those who are unemployed. Thus, NADA’s Career Counseling Model had been developed to intervened with the unemployment issue among drug addicts to prevent relapse. 25 participants had been involved in this research with the aimed to identify the effectiveness of NADA’s Career Counseling Model through a qualitative approach. 10 sessions had been conducted with directed counseling module which emphasized on the self-concept and career maturity of the former drug addicts. Facilitator's observation, semi-structured written interview, and in-depth interview had been considered as the research finding to determine the effectiveness of the Career Counseling Model in enhancing their self-concept and career maturity.
Self-esteem and coping skills of victims and nonvictims of bullying in public school

Good self-esteem and coping skills are essential to maintain a strong, happy and healthy life. The present study examined the self-esteem and coping skills of victims and non-victims of bullying in public school. The sample consisted of 150 participants (75 bullied and 75 non-bullied) who were selected through convenience sampling technique from different public schools of Dhaka city. The Bangla version of the California bullying victimization scale, the Rosenberg’s self-esteem scale and the coping scale were used to achieve the research objectives. Result of the study showed that bullying was negatively correlated with self-esteem and coping skills whereas self-esteem was positively correlated with coping skills. Result also showed that there were significant differences in self-esteem and in coping skills between victims and non-victims of bullying. The findings of the present study will advance our understanding about the negative impact of bullying on children’s mental health and will help mental health professionals to develop bullying awareness program for teachers and parents.

Effects of protein modification on textural properties and water holding capacity of heat induced turkey breast meat gels

The main objectives of this research were to examine effects of protein modification (protein cleavage and crosslinking) on turkey meat gelation and to evaluate textural properties and water holding capacity of meat gels prepared from normal and PSE (pale, soft, exudative) turkey breast meat. First, the effect of protein degradation on turkey breast meat gelation was studied. To create different extent of proteolysis in the meat, α-chymotrypsin (EC 3.4.21.1) was added to normal and PSE meat batters at 0, 2.5, 5 and 10 ppm levels. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) of cooked meat gels showed progressive protein hydrolysis with increasing enzyme level. Texture profile analysis and torsional analysis of the cooked meat gels showed an incremental deterioration in texture with increasing enzyme level. This inferior texture caused by proteolysis was similar to that observed in the gels made from PSE turkey meat alone. Pearson correlation coefficients indicated gel textural properties and expressible moisture were highly correlated to the degree of proteolysis, especially to that of myosin heavy chain (p < 0.001). The second study focused on modifying protein size to improve meat gelation, especially PSE meat gelation. Transglutaminase (TGase, EC 2.3.2.13) was chosen due to its ability to catalyze crosslinking of proteins. Pea protein isolate, an alternative to soy protein, was also evaluated as a meat protein extender. Textural profile and torsional gelometry analyses of the cooked meat gels showed TGase alone significantly (p < 0.05) increased gel texture, especially for those made from PSE meat. However, cook yield of the meat gels was compromised possibly due to steric effects. Addition of
A Phylogenetic Investigation of the New Zealand 
Pteridaceae Ferns

The fern family Pteridaceae is among the largest fern families in New Zealand. It comprises 17 native species among five genera. Traditionally the classification of Pteridaceae was based on morphological characters. The advent of molecular technology, now makes is possible to test these morphology-based classifications. The Pteridaceae has previously been subjected to phylogenetic analyses; however representatives from New Zealand and the South Pacific have never been well represented in these studies. This thesis research aimed to investigate the phylogenetic relationships of the New Zealand Pteridaceae, as well as, the phylogenetic relationships of the New Zealand species to their overseas relatives. The DNA sequences of several Chloroplast loci (e.g. trnL-trnF locus, rps4 and rps4-trnS IGS, atpB, and rbcL) were determined and the phylogenetic relationships of the New Zealand Pteridaceae and several species-specific question within the genus Pellaea and Adiantum were investigated. Results presented in this thesis confirm previously published phylogenetics of the Pteridaceae, which show the resolution of five major clades, i.e.,cryptogrammoids, ceratopteridoids, pteridoids, cheilanthoids, and the adiantoids. The addition of the New Zealand species revealed a possible South West Pacific groups formed by the respective genera, where New Zealand species were generally more related to one another than to overseas relatives. Within the New Zealand Pellaea, the analysis of the trnL-trnF locus sequence data showed that the morphologically-intermediate plants P. aff. falcata, responsible for taxonomic confusion, were more closely related to P. rotundifolia than to P. falcata. Furthermore, the species collected on the Kermadec Islands, previously thought to be P. falcata, are genetically distinct from the Australian P. falcata and they could constitute a new species. Adiantum hispidulum, which is polymorphic for two different hair types being used to distinguish them as different species, was also reinvestigated morphologically and molecularly. Morphological inspection of hairs revealed three hair types as opposed to the previous thought two, and furthermore, they correspond to three different trnL-trnF sequences haplotypes.

Inventário da malacofauna límnica de três grandes reservatórios do sertão de Pernambuco, Brasil

The construction of reservoirs to meet the needs of the human population carries serious damage to aquatic environments, such as loss of diversity, dominance of invasive species and the introduction of exotic species. In these environments, the diversity of the molluscs is notable for presenting high species richness, abundance and biomass. The objective was to inventory the mollusk species in three large reservoirs of the interior of Pernambuco. Collections were made with the aid of a hand net with a mesh aperture of 2 mm, with three replicas at six stations in each reservoir. The collected material was packed in plastic bags, labeled and preserved in 70% alcohol. The richness, density, frequency of occurrence, relative abundance, Shannon-Wiener, evenness and the Berger-Parker index were analyzed. In total, six species of molluscs were recorded: Anodontites trapesialis (Lamarck, 1819), Biomphalaria straminea (Dunker, 1848) Pomacea lineata (Spix, 1827), Melanoides tuberculatus (Muller, 1774), Corbicula fluminea (Muller, 1774) and Aylacostoma sp. , characterized by four native and two exotic species, with a total abundance of 19,179 individuals for the three reservoirs. In all reservoirs, it was evident the dominance of invasive exotic species Melanoides tuberculatus that showed high density values ranging from 1673.92 ind. /m², 1052.25 ind. /m² and 2035.25 ind. /m² for the reservoirs Entremontes, Poco da Cruz and Serrinha, respectively. It is concluded from this study for the similarity between the reservoirs regarding the described species and there is dominance of exotic and invasive species Melanoides tuberculatus , being the responsible for the low values of diversity and evenness.
Differentiation between closely related lentil (Lens culinaris Medik.) cultivars using DNA markers

The DNA polymorphism detected by analysis of variable number of tandem repeats (VNTR), (microsatellite and minisatellite DNA sequences), inter-simple sequence repeats (ISSR), and amplified fragment length polymorphism (AFLP) has been used to distinguish between commercial lentil cultivars (Lens culinaris MEDIK.) that are closely related or identical by pedigree and agronomical and morphological traits. The DNA marker systems used generated polymorphic DNA banding patterns and the lentil cultivars examined could all be differentiated from each other.
Peptide Repertoire Changes Caused by Defects in Antigen Processing

Peptide Repertoire Changes Caused by Defects in Antigen ProcessingByKristin Camfield LindDoctor of Philosophy in Molecular and Cell BiologyUniversity of California, BerkeleyProfessor Nilabh Shastri, ChairMHC I molecules display peptides derived from intracellular proteins on the cell surface for recognition by CD8+ T cells. Presentation of these peptide:MHC I complexes (pMHC I) is important for elimination of viruses and transformed cells. In order to generate an effective CD8 T cell response, a high-quality set of pMHC I must be presented. However, the editing mechanisms that select these optimal pMHC I are not clear. In these studies, we used biochemical and immunological methods to examine the role of two ER-resident pMHC I editors, tapasin and ERAAP in shaping the pMHC I repertoire. Analysis of tapasin-deficient mice revealed a qualitative loss as well as gain of some pMHC I. However, these changes did not overlap with the ERAAP-unedited pMHC I repertoire, indicating that tapasin edits peptides in a distinct way. Sequencing of peptides unique to tapasin-deficient cells revealed altered C-termini, suggesting that tapasin determines the peptide C-terminus while ERAAP shapes the peptide N-terminus. We separately examined the allele-specific effects of ERAAP-deficiency on the H-2d pMHC I repertoire. In addition to Kd and Dd, these mice express Ld, an MHC I molecule which is particularly affected by loss of ERAAP. We found that ERAAP-deficiency has distinct effects on the peptide repertoire presented by each MHC I molecule. Analysis of the peptide sequences revealed unique peptides bound to all three MHC I, although long, structurally unique peptides were only found on Dd and Kd. Furthermore, using a T cell hybridoma specific for loss of ERAAP function, we identified and characterized an ERAAP-unedited peptide presented by Dd. Together, these findings highlight the importance of both tapasin and ERAAP in determining an optimal pMHC I repertoire.
The complete chloroplast genome of Cymbidium maguanense (Orchidaceae)

Abstract Cymbidium maguanense is a valuable orchid endemic to China, with delicate smelling, ivory white flower, and showy yellow labellum. Herein, we reported the complete chloroplast genome of C. maguanense. This chloroplast genome was 156,530 bp in length. It presented a typical structure including a large single-copy region (LSC, 85,112 bp), a small single-copy region (SSC, 17,874 bp), and two inverted repeat regions (IRs, 26,772 bp). It contained 138 genes, 37 tRNA, and 8 rRNA with an average GC content of 36.8%. Besides, the phylogenetic analysis showed that C. maguanense displayed a closer kinship to C. eburneum in the section Eburnea under subgenus Cymbidium. This chloroplast genome will provide a reference for future studies on species evolution, germplasm resources utilization, and genetic engineering of genus Cymbidium.
