Influences of Nuclear Mass, Size, Shape and Spin on Chemical Isotope Effect of Titanium

Titanium isotopes of Ti (III) or Ti (IV) were fractionated by liquid-liquid extraction system using dicyclohexano-18-crown-6. The nuclear size and shape effect and the nuclear spin effect resulted in the breakdowns of the linear dependency of the enrichment factors to the mass difference. The nuclear mass effect, the nuclear size and shape effect and the nuclear spin effect were calculated by the isotope pair evaluation method. The nuclear mass effects were 0.000634 for 48Ti-46Ti (III) and 0.000559 for 48Ti-46Ti (IV), where the total enrichment factor were 0.000989 and −0.000166, respectively. The nuclear size and shape effects were 0.000356 for 48Ti-46Ti (III) and −0.000725 for 48Ti-46Ti (IV). The nuclear spin effects were 0.000180 for 47Ti (III), 0.000369 for 49Ti (III), −0.000303 for 47Ti (IV) and −0.000526 for 49Ti (IV). The ratio of chemical effect given by the field shift of 3d-orbital to that of 4s-orbital was −1.54, which had same direction and quantity with the field shift ratio of 3d-orbital to 4s-orbital in Ti I in atomic spectra. This showed that the nuclear size and shape effect on the chemical isotope effect directly reflected the field shifts of Ti I. The nuclear spin effect was the function of the number of the hyperfine splitting vibrational energy levels and the coordination number. This effect was found when the coordination numbers differ nonstoichiometrically between the aqueous phase and the organic phase.
Preservice Teachers in Special Education: Using Edublogs for Transition Collaboration.

This was an exploratory study that examined the introduction and use of Edublogs as a collaborative communication tool in an undergraduate preservice special education course. Participants were enrolled in a course that addressed transition and the development of individualized transition education plans for students with disabilities. Pre-and-post surveys were given to determine participants’ knowledge, feelings, and experiences with the use of Edublogs, as well as their attitudes before and after the introduction and use of Edublogs. Inferential and qualitative data analyses were used to analyze results. Using a 7-point Likert scale with multiple item pairs, results of pre-and post-survey ratings indicated that participants’ attitudes were significantly different in five out of fifteen variable pairs. Post-survey comments on knowledge, thoughts, and experiences revealed overall positive themes about the use of this Web 2.0 technology for
Sustainability, innovative orientation and export performance of manufacturing SMEs: An empirical analysis of the mediating role of corporate image

Purpose: The objective of this research is to empirically analyze the role played by corporate image, sustainability, and innovative orientation on export performance. Design/methodology/approach: hypothesis testing was conducted with a sample of 180 manufacturing SMEs in Seville (Spain) and a structural equation system is modeled using the technique Partial Least Squares (PLS). The research model includes the following variables: corporate image, sustainability, and innovative orientation on export performance. Findings: The results show the positive effect of sustainability and innovative orientation on export performance, as well as the mediator effect of corporate image on these relationships. Research limitations/implications: The results may be more general if we had used a national sample and cross cultural. The conclusions cannot be directly extrapolated to other countries. This work propose future research doing the same study with other types companies. Originality/value: Corporate image requires special attention, as it acts as a filter of the impacts of sustainability and innovative orientation. The creation of corporate image not only as a result of tangible items, but as a result of the actions and behavior of the company. In this research is showed that there is a high level of complexity in the management of intangibles since the intangibles influence each other, such as the influence of sustainability and innovative orientation on corporate image. Managers should focus on proper design and management of the company image, in order to compete and grow in the international area.
Generalized Love waves

We present a generalized dispersion equation for shear horizontally polarized acoustic waves in a system of a finite-thickness substrate covered by a finite-thickness solid layer having a lower shear acoustic speed. The solutions to the equation describe both layer-guided Love waves and resonant acoustic plate modes. We identify higher-order mode Love waves as continuations from the lowest-order acoustic plate mode associated with the previous Love wave mode. Experimental results are presented that confirm the relationship between the multiple Love wave modes and the acoustic plate modes.
New chemometric strategies in the spectrophotometric determination of pKa

In this work, principal component regression and partial least squares regression were used for the estimation of acid dissociation constants through UV-Vis spectrophotometric measurements, considering five well-known acid-base indicators as well as two herbicides as analytes. In each case, an acid-base titration was carried out. Then, the multivariate calibration model was constructed with a few absorption spectra of the series at extreme pH values, to which values of the dissociation fraction (α) of 1 or 0 were assigned, in the case of HA or Aspecies. After that, the prediction step consisted in the estimation of α for the rest of the series. Then, distribution diagrams were built up with α vs pH, to find α = 0.5 where pH = pK a . The results were compared with those obtained through multivariate curve resolution-alternating least squares and program stability quotients from absorbance data (SQUAD), which showed an excellent correspondence.
Assessment instrument for practicum skills in Trimyristin separation for undergraduate students

Assessment of practicum plays an essential role in gaining knowledge and skill. Because practical work is an essential component of science courses, there were need to develop new instruments to examine practicum skill. To gain the purpose, Research and Development method used, Borg and Gall's model was adopted in this research. Observation sheets were used to obtain data. The qualitative data analysis technique was used to make coding. The data were described using descriptive statistics. It was used to determine the ability of students to practice in general, purposive sampling technique used for data collection. Products of practical’s skills assessment contain four aspects, fifteen indicators, and four criteria. The product was validated by two expert judges, shortcomings and grammatical mistakes were revised. In the separation of trimyristin, mostly student practicum skill was "good" while few students’ skills were "very good" and few other students earned “sufficient” none of them got “poor” and “very poor”. In each aspect of practicum skills “very good” in drawing, experimental and observations skills were “good” while reporting and interpretive skills were “sufficient”. For further dissemination, the reliability test can be done by using inter-rater reliability test to make the product more efficient and applicable.
IS TEACHERS’ KNOWLEDGE A REASON FOR STUDENTS’ POOR PERFORMANCE IN LATITUDE AND LONGITUDE IN NIGERIA SECONDARY SCHOOLS?

Latitude and Longitude, is one of the topics in mathematics in the West African Examination Council syllabus. Over the years, chief examiners’ reports reveal that students’ performances in the topic have been generally poor. This study sought to find the reasons for students’ poor performance in the topic from teachers. A random sample of 100 Mathematics teachers from 20 secondary schools in four Local Government Areas of Ogun State, Nigeria participated in the study which employed descriptive survey research design. Data was collected using Teacher Questionnaire on Reasons for students’ Poor performance in Latitude and Longitude (TQRPLL) and analysed using descriptive statistics. Findings revealed that most of the teachers lacked understanding of the topic and find it difficult to effectively teach it. Based on these findings, it is recommended that the topic should be included in the teacher education curriculum as it is currently not taught at the universities or colleges of education where the teachers are trained.
Structure and Performance Analysis of Multi Stage Biometric Cryptosystem

The system aims to bind many biometric cryptosystem using a linker and to increase the matching accuracy at low threshold values. We demonstrate a two stage biometric cryptosystem in which each system uses two different biometric templates. Shielding functions is used to encrypt the biometric template. A OneTime Seed (OTS) generated by the OTS generator is used to link the two biometric cryptosystem. Hash algorithm principle is applied to generate OTS. Finally, the performance of the system is analyzed in terms of False Acceptance Rate (FAR) and False Reject Rate (FRR) for the biometric cryptosystem whereas many classic and contemporary biometric cryptosystem work well at high threshold values, but sharply falls when the threshold values are lowered in the matching process.

Pattern of Fertile Period in Kadaknath Using Fresh vs Preserved Semen

The attempts have been made to examine fertility pa ttern in fertile period in Kadaknath chicken using fresh vs preserve d semen. For this study 60 female and 30 male birds from each breed were taken. Standard procedures were used for semen collection, dilution , artificial insemination and fertility examination. The fertility pattern in fertile period of fresh 0, 6 and 24 hr stored semen (at 3-5 0 C) in all diluents (normal saline, CARI semen diluent, Beltsville Poultry Semen Extender (BPSE), and Lake's semen diluents) was determined in 60 healthy hens f rom same breed using Artificial insemination (A. I.) technique. A. I. wi th freshly ejaculated semen (0 hr) indicated that fertilizing ability of sperma tozoa in fertile period was reduced gradually and significantly (P<0.05) with t he increase of duration after artificial insemination (AI) (from 2-12 days) irrespective of the diluents. Similarly a gradual reduction in fertilit y along with enhancement of fertile period was examined at 6 and 24 hr store d Kadaknath chicken semen. Fertility in fertile period was found very p oor in the semen stored and diluted with normal saline for 6 hrs, whereas i n the same diluent, no fertility after 24 hrs storage of semen. At all the semen storage period (0, 6 and 24 hrs), CARI semen diluent showed numerically higher fertility in fertile period than other diluent. From this study it may be concluded that CARI diluents is better than other diluents for sho rt term storage of Kadaknath semen at refrigerated temperature.

A new hanging parrot from Camiguin Island, Philippines

In 2004 I learnt that ornithologists from the Field Museum in Chicago were going to describe a new form of the Philippine Hanging Parrot Loriculus philippensis. They had noticed that specimens from the small island of Camiguin taken in the 1960s were apparently different from nearby Mindanao’s race apicalis to which they had hitherto been assigned. Male specimens from Camiguin lack the red throat-spot typical of these hanging-parrots. Moreover, Camiguin birds have distinctly longer tails and wings, the blue part of the cheek is more extensive, the red on the top of the head goes less far down the neck, and the green body plumage is darker, less yellowish, than in apicalis. All in all the Field Museum team had 23 specimens at their disposal, of which only four were female. Of course, theoretically there was the possibility that the 19 males were wrongly sexed or were young birds, but this seemed rather improbable. According to the team’s analyses, the Camiguin birds were, in fact, a new species. Their main argument was that the geographical location of the island and its proximity to Mindanao could not have generated such distinct morphological differences unless the population had been isolated for a very long time. If it had been just a normal subspecies, its coloration would have to have been between L. p. worcesteri on Bohol and Leyte and L. p. apicalis on Mindanao, which are the neighbouring populations to the north and south of Camiguin. I was not entirely sure whether the males really did not differ from the females, since on a trip to the Philippine islands of Luzon, Leyte and Samar in December–January 2004–2005 I had indeed seen males which could be identified by the red throatspot but, strangely, with the locals I had only seen females and males that had no full colouring. In one of the bird markets in Manila I even discovered a cage with about 50 Philippine Hanging Parrots, among which there was not a single full-coloured male. So I quickly decided that on my next trip to the Philippines, on which I was planning to search for racquet-tails Prioniturus, I would have to make a trip to Camiguin. This I did in January this year. Before I left the Chicago team sent me a first draft of their planned description and a request to check their data in the field, and if possible to check out the current status of the population.

The Effect of Visual Merchandising, Sensational Seeking and Collectivism on Impulsive Buying Behavior

Abstract The aim of this paper is to measure the effect of sensational seeking, visual merchandising and collectivism on impulsive buying behavior. Valid sample size for this study was 300 comprising of all age groups. Mall intercept method which is a kind of convenience sampling was used for collecting the data. The data was collected by preselected enumerators. Scale used for this study had established reliabilities. After ascertaining the normality of data a typical multiple steps, procedure was adopted for this study. The conceptual framework tested through Structural equation modeling and was found to be relevant in understanding the impact of predictor variables on impulsive buying behavior. A strong and positive relationship was found between sensational seeking, and no relationships were found between, collectivism and impulsive buying, and visual merchandising and impulsive buying. One of the contributions of this study is that it has explored the relationships of collectivism, and sensational seeking with impulsive buying which have not been explored that extensively.
Solving Rolling Contact Problems Using Boundary Element Method and Mathematical Programming Algorithms

In this work an approach to the two-dimensional steady-state rolling contact problem, with and without force transmission, is presented. The problem is solved by the combination of the Boundary Element Method with a formulation of the variational inequalities that govern the problem in the contact area, producing finally a mathematical programming problem. This formulation avoids the direct use of the contact constrains, but it drives to the minimisation of a nondifferentiable function, being necessary the use of an specific numerical tool as the modified Newton’s method. keyword: Rolling, Contact, Mathematical Programming, Boundary Element Method.
Astrometric Discovery of GJ 802b: In the Brown Dwarf Oasis?

The Stellar Planet Survey is an ongoing astrometric search for giant planets and brown dwarfs around a sample of ~30 M dwarfs. We have discovered several low-mass companions by measuring the motion of our target stars relative to their reference frames. The lowest mass discovery thus far is GJ 802b, a companion to the M5 dwarf GJ 802A. The orbital period is 3.14 ± 0.03 yr, the system mass is 0.214 ± 0.045 M☉, and the semimajor axis is 1.28 ± 0.10 AU or 81 ± 6 mas. Imaging observations indicate that GJ 802b is likely to be a brown dwarf with the astrometrically determined mass 0.058 ± 0.021 M☉ (1 σ limits). The remaining uncertainty in the orbit is the eccentricity that is now loosely constrained. We discuss how the system age limits the mass and the prospects of further narrowing the mass range when e is more precisely determined.
Informed trading before rights issues

This paper provides evidence of informed trading before and after a rights issue. First, we find significant net buying and selling activity by informed traders prior to the announcement date leading to a temporary price pressure effect. Even though those results are consistent with the presence of short-term manipulative traders, we find little evidence of manipulative trading on announcement effects. Second, we show that informed traders are able to identify the issuer’s quality once all issue characteristics have been released. They trade in a direction consistent with their private information before and after the issue: they will buy (sell) shares in SEO firms with better (worse) post-issue price performance leading to a permanent price impact.
Incorporation of iron and organic matter into young Antarctic sea ice during its initial growth stages

This study reports concentrations of iron (Fe) and organic matter in young Antarctic pack ice and during its initial growth stages in situ. Although the importance of sea ice as an Fe reservoir for oceanic waters of the Southern Ocean has been clearly established, the processes leading to the enrichment of Fe in sea ice have yet to be investigated and quantified. We conducted two in situ sea-ice growth experiments during a winter cruise in the Weddell Sea. Our aim was to improve the understanding of the processes responsible for the accumulation of dissolved Fe (DFe) and particulate Fe (PFe) in sea ice, and of particulate organic carbon and nitrogen, dissolved organic carbon, extracellular polymeric substances, inorganic macro-nutrients (silicic acid, nitrate and nitrite, phosphate and ammonium), chlorophyll a and bacteria. Enrichment indices, calculated for natural young ice and ice newly formed in situ, indicate that during Antarctic winter all of the measured forms of particulate matter were enriched in sea ice compared to underlying seawater, and that enrichment started from the initial stages of sea-ice formation. Some dissolved material (DFe and ammonium) was also enriched in the ice but at lower enrichment indices than the particulate phase, suggesting that size is a key factor for the incorporation of impurities in sea ice. Low chlorophyll a concentrations and the fit of the macro-nutrients (with the exception of ammonium) with their theoretical dilution lines indicated low biological activity in the ice. From these and additional results we conclude that physical processes are the dominant mechanisms leading to the enrichment of DFe, PFe, organic matter and bacteria in young sea ice, and that PFe and DFe are decoupled during sea-ice formation. Our study thus provides unique quantitative insight into the initial incorporation of impurities, in particular DFe and PFe, into Antarctic sea ice.
Control of Cucumber Damping-off in the Field by the Bio-Agent Trichoderma harzianum

Biological control of plant pathogens is becoming an important component in plant disease management. Pythium aphanidermatam is one of the most serious pathogens in cucumber at seedling stage, and can cause both pre- and post-emergence damping-off. Trichoderma spp. appeared to be effective in controlling soil-borne pathogenic fungi. Therefore, the present study aimed at assessing the efficacy of Trichoderma harzianum in controlling cucumber damping-off under field conditions. The current field study was carried out at Agricultural Research Station, Faculty of Agriculture, Mutah University, Jordan during the growing season (April-May, 2012). Six different treatments were used in this study. Disease incidence and severity (pre- and post-emergence damping-off), and disease control percent were recorded. Results indicated that adding T. harzianum to the infested soil significantly reduced pre-emergence damping-off in cucumber. On contrast, in case of post-emergence there were no significant differences between the pathogen and the treatments using the bio-agent as conidia or conidial preparation. In the mycelium and mycelia preparation treatments, the damping-off decreased significantly when compared to all treatments. Addition of all bio-controling agents reduced significantly total damping-off. The highest reduction in damping-off percentage was recorded by T. harzianum when used as a mycelial preparation where it reached 70%. T. harzianum decreased disease severity to 16% in mycelial preparation treatment when compared to P. aphanidermatum treatment, where it reached up to 73%. In conclusion, T. harzianum has the ability to suppress damping-off in cucumber caused by P. aphanidermatum under field conditions, and increases the efficiency by supply foods to stimulate development by increasing the population and increase antibiotic products.
