  • Paclobutrazol influences post harvest life of Mango Cvs. Dashehari, Langra, Chausa and Fazri

    The treatment consisted of different doses of Paclobutrazol (PP333) namely 1.0g and 0.5g/canopy diameter along with control. Paclobutrazol was applied once in a year 15 October 1997 and 15 September 1998 in soil around the tree canopy spread. Paclobutrazol did not affect on Sugar, pH, Colour, K or glucose-fructose ratio, reduced sugar concentration and did not effect TSS and Firmness of Apple, increased TSS, Ascorbic Acid, Chlorophyll, ß-carotene, amylase, peroxides activity for 12 days in Dashehari Mango in storage at ambient temperature (30-33°C), chemical used Paclobutrazol [(2RS, 3RS)-1-1(4-Chlorophenyl)-4, 4-dimethyl-2-(1,2,4-trizol)-1-yl)] Pentan-3-ethanol.

  • Biochemical and Biological effects of Kaurene oxidase inhibitor such as Paclobutrazol on vegetative in Mango Cvs. Dashehri, Langra, Chausa and Fazri

    The compound Paclobutrazol [(2RS, 3RS)-1-(4-chlorophenyl)-4, 4-dimethyle-2- (1, 2, 4 Triazol-1-y)] pentan-3-ethanol was the action of this retardants can be antagonized by Gibberellins (GA3) and ent-Kaurenoic acid. The growth regulating properties of paclobutrazol are mediated by changes in the levels of important plant hormones including the gibberellins (GAs), abscisic acid (ABA) and cytokinins (CK). Paclobutrazol (PBZ) affects the isoprenoid pathway, and alters the levels of plant hormones by inhibiting gibberellin synthesis and increasing cytokinins level. When gibberellins synthesis is inhibited, more precursors in the terpenoid pathway accumulate and that resulted to the production of abscisic acid. PBZ has been used to provide plant protection against numerous abiotic stresses such as chilling, water deficit stress, flooding and salinity. Paclobutrazol acts as stress protectant by maintaining relative water content, membrane stability index, photosynthetic activity, and photosynthetic pigments and protects the photosynthetic machinery by enhancing the level of osmolytes, antioxidant activities and level of endogenous hormones and thereby enhances the yield. It is suggested that its main biochemical action is to block the reactions that lead from ent-Kaurene to ent-Kaurenoic acid in the course of Gibberellins biosynthesis courses, reduced vegetative growth more intensively than root growth by this compound.

  • Adolescent Violence: A Narrative Review

    This narrative review is based on a literature search on PsycINFO and PubMed entering the terms adolescent violence for papers published during the last five years. Following exclusion criteria, 58 papers could be classified as school–based violence (fighting) and dating violence including research on the prevalence and risk factors for these types of violence. The prevalence of school violence has varied by ethnicity, type of violence and culture. The risk factors for school violence are both intrapersonal and interpersonal. The intrapersonal factors include male gender, minority status, middle school level, maladaptive cognitive/ emotional strategies, depression, callous behavior, conduct problems, low cortisol and high testosterone, unhealthy conditions including concussions and obesity, drug abuse, self-harm, suicidal ideation and carrying weapons. The interpersonal factors include a lack of parental monitoring, conflict and violence in the family, exposure to violence and to violent social media. The prevalence of dating violence has also varied by gender and culture. The intrapersonal risk factors have included externalizing behavior, sexting both off-line and online, alcohol and marijuana misuse. The interpersonal risk factors include anxious attachment, family violence and peer rejection. Surprisingly, given the prevalence and severity of these problems, very little prevention/intervention research appears in this recent literature. Research is also missing on peer relationships, empathy and psychopathy as potential risk factors. Like other literature on adolescent problems, this research is limited by primarily deriving from self–report, parent report and hospital records.

  • Psychological Availability, Psychological Safety and Optimism as Predictors of Innovative Behavior among Workers

    The study examined psychological availability, psychological safety and optimism as predictors of innovative behavior at work among administrative staff of Federal Teaching Hospital Abakaliki (FETHA). A total of 120 workers comprising of 82 males and 38 females were used for the study with the mean age of 32.5, standard deviation of 11.2 and age range of 19-60. The participants were selected through multi stage sampling technique, Comprising of randomization and convenience sampling technique. The study made use of four instruments namely Psychological availability scale by Doglass (2004), psychological safety scale by Brown & Leigh, (1996), Life Orientation Test (LOT) developed by Scheier and carva (1985) to measure optimism and Innovative Work behavior Scale by Kleysen and Street (2001). The design for this study was a cross sectional survey design and hierarchical multiple regression was used for data analysis. The study tested three alternate hypotheses. Findings indicated that Psychological availability significantly predicted innovative behavior at work at β=.19.p< 0.01 which accepted hypothesis one. Psychological safety significantly predict innovative behavior at work at β=13,p

  • Comparison between creatine monohydrate and creatine HCl on body composition and performance of the Brazilian Olympic team

    Weight-dependent athletes have trouble to balance the energy consumption to the needs of the sport they practice. As performance depends on that balance, it would be ideal to find a supplement that would be ergogenic without promoting weight increase. Monohydrate creatine supplementation is effective to improve strength and power but water retention and weight gain are side effects that avoid its use. An alternative molecule, creatine HCl, proposes the same an ergogenic effects without the undesirable effects. So, this study compared the effects of both creatines on performance and body composition of elite gymnastics athletes. 11 males, 18 to 25 years old took part into the randomized cross-over model: Creatine Monohydrate Supplement (MCG), resistant starch (RS) and HCl Supplement (HClG). Pre and Post all the experimental conditions, body fat percentage, body weight, lean body mass and total water amount were measured, bench press and leg press 1RM test were also carried out. Lean mass increased with both treatments (p

  • A Note on Statistical Arbitrage and Long Term market Efficiency

    Market efficiency is a central topic in finance. The notion of statistical arbitrage is a suitable instrument to investigate market efficiency without the need to specify an equilibrium model. We introduce a new definition of statistical arbitrage (named Strong Statistical Arbitrage, SSA in the following) modifying the original definition in an apparently infinitesimal way. We show that some simple investment strategies, recognized as statistical arbitrages by the standard definition, do not test positive for SSA. We discuss the relations between the proposed definition and common definitions of arbitrage and prove that SSA is compatible with deviations from market efficiency in a “short term frame.” The idea is that if market anomalies are small, the markets do not deviate significantly from efficiency, while an SSA requires time persistent anomalies on asset prices.

  • The Effect of Nitrendipine and Levetiracetam in Pentylenetetrazole Kindled Rats

    We aimed to investigate the efficacy of L-type voltage gated calcium channel blocker nitrendipine and levetiracetam in pentylenetetrazole (PTZ) kindled male rats. In order to establish kindling model, 35 mg/kg PTZ injected intraperitoneally (i.p.) to male wistar albino rats three days a week. Then, screw electrodes were placed in the skulls of the kindled rats. During the experiments, EEG activities and seizure behaviors of kindled rats were recorded. The kindled rats were divided into control (n=6), PTZ (n=6), nitrendipine (2.5 mg/kg (n=6), 5 mg/kg (n=6), 10 mg/kg (n=6)) and levetiracetam (10 mg/kg (n=6), 20 mg/kg (n=6), 40 mg/kg (n=6)) groups. Nitrendipine (5 mg/kg) and levetiracetam (20 mg/kg) were suppressed the spike frequency and the seizure score effectively (p0.05). The co-administration of nitrendipine and levetiracetam was not more effective than administration of nitrendipine or levetiracetam separately (p>0.05).

  • Perception of college students regarding the use of ICT: A case study in Monterrey, México

    The presenWe often take for granted that students have the basic skills and mastery of Information and Communication Technologies (ICT), however, it has been confirmed that not all students are equally competent in this regard. From the theories of socialization and acceptance of the technology, a structural equation model (SEM) is built to explore the variance in basic ICT skills levels of students at a business school. With the application of a questionnaire that measured in detail ICT skills of new students in a higher education institution in Mexico, the main findings show that according to the tables of impact value between constructs and the significance between constructs, the skills have a significant and significant negative impact on the side of anxiety / behavior and on the side of the utility there is a strong, significant impact.

  • Minimal Invasive Potential of Three Caries Excavation Methods in Children

    Background: Recently, the concept of minimally invasive (MI) dentistry has emerged. MI calls for the selective removal of heavily infected and irreversibly denatured dentin caused by carious lesions while preserving dentin that is demineralized but not infected. Aim: To compare the minimal invasive potential (MIP) of conventional caries excavation (CCE), caries detection dye (CDD), and fluorescence aided caries excavation (FACE) methods in children. Subjects and Methods: A total of 105 carious primary molars in 43 children were included in this study. The teeth were randomly divided into three groups according to the caries excavation method. Preoperative evaluation of the carious teeth was performed using digital radiography after sealing the cavities with a radiopaque material. Caries excavation was performed using CCE, CDD, or FACE method. The teeth were restored using self-cured glass ionomer. Post-operative radiographic examination was then performed. Pre-operative and post-operative widths and depths for the cavities were assessed. MIP was determined by comparing the prepared-cavity width and depth relative to the initial width and depth of the caries lesion, respectively. Results: There was no statistically significant difference between the MIP of examined groups neither after comparing cavity widths at p=0.253 nor depths at p=0.06. FACE showed the highest mean values of MIP potential for cavity widths (1.41±0.36) and depths (2.04±0.74). Conclusions: CCE, CDD, and FACE showed comparable MIP in children.

  • Synthesis, Characterization and Catalytic Activity of Melamine-Based Dendrimer Encapsulated Pd/Cu Bimetallic Nanoparticles

    A melamine-based dendrimer was used to prepare a new class of heterogeneous Pd/Cu bimetallic nanoparticles (NPs). The physicochemical characteristics of Pd/Cu bimetallic NPS were studied with the aid of SEM, EDX, XRD, TG& DSC techniques. Leafs shape surface morphology and the presence of required palladium and copper ion were observed from SEM and EDX analysis respectively while TG& DSC showed good thermal stability, as well as XRD, revealed nano-shape FCC structure. The recycling ability of the catalyst was examined for five successive runs without any noteworthy loss of activity. The synthesized Pd/Cu bimetallic NPS exhibited high catalytic activity in the synthesis of ynone in which synthetic route was phosphine ligand-free.
