Postharvest practices for managing the quality of longans and rambutans.

Research was conducted to integrate preharvest disease control methods and postharvest practices to manage diseases, improve fruit quality, and extend the shelf-life of longans and rambutans exported from Hawaii. The main pathogens of longan and rambutans were isolated and identified as Lasmenia, Colletotrichum, Pestalotiopsis and Phomopsis. In vitro sensitivity of these pathogens to registered fungicides was established, and Serenade ® (a patented strain of Bacillus subtilis) was 100% effective at all test concentrations. However, when Serenade ® was applied as a preharvest field treatment, it did not control postharvest diseases or improve quality of rambutans or longans. In postharvest studies, optimum storage temperatures and packaging systems were established. Package treatments included microperforated bags, clamshell containers, Peakfresh ® film, and Lifespan ® film. For longans, the sensory quality was maintained, overall disease incidence minimized, and shelf-life extended when microperforated packages or clamshell containers were stored at 10°C. The modified atmospheres (15% CO 2 and 7% O 2 ) inside Peakfresh ® packages adversely affected longan flavor. Rambutans stored in the clamshell, microperforated bag, or Peakfresh ® packages had higher visual quality ratings and lower disease incidences when stored at constant 10°C compared to simulated shipping temperatures. Rambutans held under simulated shipping temperatures in microperforated bags or clamshells had disease incidences that were 2-3 times higher than when stored at constant 10°C. Rambutans stored in Peakfresh ® packages had the best overall quality ratings and lowest disease incidence, but lowest flavor ratings.
Spin-orbit coupling in quasiparticle studies of topological insulators

We present one-shot GW calculations of the bulk electronic structure of the topological insulators Bi2Se3 and Bi2Te3 within the all-electron full-potential linearized augmented-plane-wave formalism. We compare three different ways of treating the spin-orbit interaction in calculating the quasiparticle energies: (i) The spin-orbit coupling (SOC) is already incorporated in the noninteracting system that serves as starting point for the quasiparticle correction. (ii) The SOC is added in a second-variation approach only after the quasiparticle calculation has been performed in the absence of SOC. We found that the approximate treatment (ii) yields most quasiparticle bands with reasonable accuracy but does fail in the important band-gap region, where the SOC gives rise to a band inversion relevant for the topological properties of these materials. For example, Bi2Se3 is just on the brink of becoming a trivial semiconductor within this approximate approach, while it maintains its topological properties in the case of the consistent treatment (i). Finally, we consider another approach (iii), in which the SOC is included in the Green function G as in (i), but neglected in the calculation of the screened Coulomb potential W . This approach gives results in very good agreement with the full treatment (i), but with a smaller numerical effort. We conclude that, in the high-symmetry directions studied, bulk Bi2Se3 is a direct-gap and Bi2Te3 an indirect-gap semiconductor with band gaps of 0.20 and 0.19 eV, respectively.
Geographic variation in diversity of wave exposed rocky intertidal communities along central Chile

A lo largo de la costa de Chile central, los patrones geograficos de diversidad han sido inferidos a partir de revisiones literarias y colecciones de museos para algunos grupos taxonomicos. Sin embargo, aun no contamos con una evaluacion integral, y en terreno, de la riqueza de especies macrobentonicas intermareales. En un estudio de largo plazo conducido entre 1998 y 2005 caracterizamos los patrones latitudinales en la biodiversidad del intermareal rocoso en 18 sitios a lo largo de la costa de Chile central (29-36° S). En cada sitio, el numero de especies sesiles y moviles fue cuantificado en cuadrantes de 0.25 m2. Usamos dos estimadores de la riqueza de especies: la riqueza local observada, correspondiente a la asintota de la curva de acumulacion de especies, y el indice Chao2, el cual considera el efecto de especies raras en la estimacion de la diversidad local. Identificamos 71 especies pertenecientes a 66 generos y a un total de 86 taxa. Los grupos mas diversos fueron moluscos (27 taxa) y macroalgas (43 taxa). La riqueza de especies mostro un patron complejo en el cual areas de alta riqueza especifica aparecieron intercaladas con areas de baja riqueza. Ademas, observamos una alta variabilidad espacial en el numero de especies herbivoras y un patron latitudinal inverso en el numero de especies algales. Nuestros resultados apuntan a la necesidad de incorporar una variedad de grupos taxonomicos y un rango de escalas espaciales en estudios de biodiversidad.
Landscape Performance, Flowering, and Seed Viability of 15 Japanese Silver Grass Cultivars Grown in Northern and Southern Florida

ADDITIONAL INDEX WORDS. variety trialing, invasive, ornamental grass, Miscanthus sinensis SUMMARY. Japanese silver grass (Miscanthus sinensis) and 14 cultivars were trans- planted in northern and southern Florida and evaluated for landscape perfor- mance, fl owering, growth, and seed viability. All plants survived the 84-week study at both locations with the exception of 'Morning Light', where 22% to 33% of the plants died. In northern and southern Florida, 'Arabesque', 'Adagio', 'Cosmopolitan', and 'Gracillimus' received the highest visual quality ratings on average throughout the entire study, yet other cultivars such as 'Central Park' and 'Silberfeder' performed well but had much narrower windows of peak per- formance. Cultivars such as 'Little Kitten' and 'Sarabande' performed far better in southern Florida than in northern Florida. Regardless of location, 'Morning Light' and 'Puenktchen' generally did not perform as well as other cultivars. In northern Florida, four consecutive months of very good to excellent fl owering (75% to 100% canopy coverage) were observed for 'Adagio', 'Arabesque', 'Cos- mopolitan', 'Gracillimus', 'Little Kitten', 'Sarabande', 'Silberfeder', and 'Zeb- rinus'. However, in southern Florida, peak fl owering periods for these cultivars were delayed and generally only lasted for 1 to 2 months. On average, plants in northern Florida were larger and produced 2.8 times more fl owers than plants in southern Florida. All cultivars produced viable seed with germination of viable seed ranging from 53.6% ('Cabaret') to 100% ('Gracillimus') in southern Florida, and from 49.8% ('Arabesque') to 100% ('Adagio', 'Little Kitten', 'Sarabande', and 'Variegatus') in northern Florida.
High Responsivity MgxZn1−xO Film UV Photodetector Grown by RF Sputtering

This letter focused on MgxZn1-xO thin films grown on quartz substrates using radio frequency magnetron sputtering. The films were then used to fabricate metal-semiconductor-metal ultraviolet (UV) photodetectors (PDs) with different flow rates of argon gas (30, 25, and 20 sccm) and oxygen gas (0, 5, and 10 sccm). We obtained the best parameters for the 25:5 sccm gas flow MgxZn1-xO UV PD. The samples' Mg content was relatively high, contributing to low dark current. Furthermore, the oxygen flow rate for 5 sccm was manipulated properly, so the film was more conductive, having a maximum responsivity of 2.133 A/W with 280-nm illumination and 10 V applied bias. The maximum photocurrent was 1.3 μA, and the device's ON/OFF current switching characteristic was very stable.
Improved detection of electrical activity with a voltage probe based on a voltage‐sensing phosphatase

• The use of genetically encoded voltage probes has been expected to enable sensitive detection of spatiotemporal electrical activities in excitable cells. • However, existing probes suffer from low signal amplitude and/or kinetics too slow to detect fast electrical activity. • We have developed an improved voltage probe named Mermaid2. • Mermaid2 provides ratiometric readouts of electrical activity with fast kinetics and great sensitivity, and was able to detect single‐event electrical activity both in vitro and in vivo. • Mermaid2 will expand our chances to analyse electrical events that have been less accessible by using other techniques.
Engineering cardiac stem cells for the treatment of the damaged heart

AMI is most often caused by the breakage of an atheroma plaque and the subsequent formation of a thrombus and occlusion of a coronary vessel, producing an acute reduction of blood supply to a portion of myocardium. Unfortunately, in adult mammals the resident cardiac cells are not able to regenerate heart tissue and restore efficiently the cardiac function in response to injury, thus, ischemia induces an irreversible damage leading to the death of cardiac tissue. It is calculated that a loss of approximately one billion cardiomyocytes occurs, which are replaced by a non-functional scar. This leads to a decrease in heart function, hypertrophy being the main compensation of the loss of cardiomyocytes, which eventually produces heart failure [2].

Determination of water and alkaline extractable atmospheric humic-like substances with the TU Vienna HULIS analyzer in samples from six background sites in Europe

[1] With a newly developed method based on the combination of two separation steps (by polarity and by acidity) with a universal detector for organic carbon, efficient isolation of humic-like substances (HULIS) from the matrix and quantitative determination of the isolated organic carbon is achieved. This new method was applied to determine the water extractable (HULISWS) and, in sequence, the 0.1 M NaOH alkaline extractable HULIS (HULISAS) fractions in aerosol from six sites situated at a transect from west to east across Europe. The sum of the two HULIS fractions is here defined as total HULIS (HULIST). The lowest 12-month average concentrations of HULIST ranged from 0.075 μgC/m3 the Azores (Portugal) to 1.7 μgC/m3 at the continental background site K-puszta (Hungary). On the continent, the HULIST concentration decreases exponentially with elevation. The relative amounts of water extractable and alkaline soluble HULIS were relatively similar at the six sites. Dramatic differences were observed for the seasonal variations of the HULIS fractions at the different sites. At the Azores, as well as at the higher mountain sites (1450 and 3100 m), a summer maximum of the HULIST concentration was observed, while at the continental low-level sites (Aveiro and K-puszta), winter maxima dominated the seasonal variation. The summer/winter ratio of the HULIST concentration varied from 7.1 at Sonnblick to 0.36 at Aveiro. The seasonal variation at the two continental lower-level sites with winter maxima might be explained by overlapping of a weaker summer source and a stronger winter source.
Proximate composition, structural characterization and phytochemical screening of the seed oil of Adenanthera pavonina linn

Adenanthera pavonina is leguminous species which is a perennial and non-climbing tree which is a highly valuable plant for food, drink, and traditional medicine. The Adenanthera pavonina Linn Seed was obtained in our institution premises. This present study was targeted at evaluating proximate analysis, phytochemical determination, a physicochemical parameter of the spectroscopically characterized oil sample of Adenanthera pavonina. The oil which was extracted by standard method had percentage yield of 15.36%. The phytochemical screening of the oil revealed the presence of saponin, alkaloid, and terpenoids. Proximate analysis result unveiled that seed oil of Adenanthera pavonina Linn had an appreciable quantity of protein 27.72%, Crude fiber 5.82 and Ash contents 2.51. It also showed the moisture content, organic matter, carbohydrate, pH and Refractive index to be 13.34%, 97.49% 54.36%, 5.96 and 1.62 respectively. The mineral determination showed that the seed oil contained Manganese (0.001 ± 0.0002 %), Iron (13.52 mg/kg), while Potassium (K), Sodium (Na), Nickel (Ni), Chromium (Cr), Cobalt (Co), Lead (Pb) and Cadmium (Cd) were below the detectable limit. The structure of the oil was elucidated using physicochemical analyses and spectral data which include FT-IR, UV, 1H- and 13C-NMR as well as mass spectral data. The spectroscopic data correlated well and was consistent with the proposed structure. The seed oil could provide access to increase dietary formulation owing to its high protein content. Keywords
evascularization of Left Anterior Descending rtery With Drug-Eluting Stents : Comparison With ff-Pump Surgery

t b l e a Background. This study compares early results of left nterior descending coronary artery stenting using drugluting stents (Cypher) with off-pump coronary artery ypass grafting (OPCAB). Methods. From June 2002 to June 2003, 386 consecutive atients underwent myocardial revascularization of the eft anterior descending coronary artery territory, 130 by ypher and 256 by OPCAB. After matching for age, sex, nd extent of coronary artery disease, two groups (each ith 94 patients) were used to compare the two revascuarization modalities. The two groups were similar; howver, old myocardial infarction and intraaortic balloon ump were more prevalent in the OPCAB group, and rior percutaneous transluminal coronary angioplasty as more prevalent in the Cypher group. Results. The number of coronary vessels treated per atient in the two groups was similar (1.54 versus 1.34, PCAB and Cypher, respectively; not significant). Mean
Workaholism and daily recovery : a day reconstruction study of leisure activities

This study among 85 individuals used a day reconstruction approach to examine whether workaholism moderates the relationship between daily activities during non-work time and daily well-being in the evening (evening happiness, momentary vigor before bedtime, and momentary recovery before bedtime). Specifically, it was hypothesized that daily work-related activities during the evening have a stronger negative relationship with daily well-being for employees high (versus low) in workaholism and that daily physical and social activities have a stronger positive relationship with well-being for employees high (versus low) in workaholism. The results of multilevel analyses largely supported the hypotheses for daily physical and work-related activities but not for social activities during non-work time. These findings imply that organizations should not encourage their employees and particularly those who score high on workaholism to work during non-work time and instead promote physical exercise.
A CW 20W Ka-band GaN high power MMIC amplifier with a gate pitch designed by using one-finger large signal models

This paper reports a 20 W Ka-band GaN high power MMIC (Monolithic Microwave Integrated Circuit) amplifier under continuous wave (CW) operation. The one-finger large signal models were made to take account of both the phase difference of RF gate voltage at a gate feeder and thermal effect. By using this model, the gate pitch length of unit cell transistor was optimally designed to obtain maximum output power as MMIC amplifier under CW operation. As a result, 21.7W output power under CW operation was successfully achieved with power added efficiency (PAE) of 19.8% at Ka-band by a single-ended MMIC. To the best of authors' knowledge, this output power is state-of-the-art for GaN MMIC amplifiers under CW operation at Ka-band.
A 4  $\times$  4 Ridge Substrate Integrated Waveguide (RSIW) Slot Array Antenna

The waveguide slot array antenna is known to suffer from a very limited frequency bandwidth, which becomes even more serious in substrate-integrated-waveguide (SIW)-based design because of its reduced waveguide height. In this work, a 4 x 4 slot array antenna based on ridge SIW (RSIW) and T-type folded SIW (TFSIW) techniques is proposed, and an 8.8% bandwidth is easily achieved. The proposed antenna structure is then fabricated. Measured results are well consistent with simulated ones.
The Mortality and Medical Costs of Air Pollution: Evidence from Changes in Wind Direction

We estimate the causal effects of acute fine particulate matter exposure on mortality, health care use, and medical costs among the US elderly using Medicare data. We instrument for air pollution using changes in local wind direction and develop a new approach that uses machine learning to estimate the life-years lost due to pollution exposure. Finally, we characterize treatment effect heterogeneity using both life expectancy and generic machine learning inference. Both approaches find that mortality effects are concentrated in about 25 percent of the elderly population.
Electro-Mechanical Coupling of Indium Tin Oxide Coated Polyethylene Terephthalate ITO/PET for Flexible Solar Cells

Electro-Mechanical Coupling of Indium Tin Oxide Coated Polyethylene Terephthalate ITO/PET for Flexible Solar Cells Mohamed Ahmed Sayed Nasr Saleh Indium tin oxide (ITO) is the most widely used transperant electrode in flexible solar cells because of its high transperancy and conductivity. But still, cracking of ITO on PET substrates due to tensile loading is not fully understood and it affects the functionality of the solar cell tramendously as ITO loses its conductivity. Here, we investigate the cracking evolution in ITO/PET exposed to two categories of tests. Monotounous tensile testing is done in order to trace the crack propagation in ITO coating as well as determining a loading range to focus on during our study. Five cycles test is also conducted to check the crack closure effect on the resistance variation of ITO. Analytical model for the damage in ITO layer is implemented using the homogenization concept as in laminated composites for transverse cracking. The homogenization techniquie is done twice on COMSOL to determine the mechanical and electrical degradation of ITO due to applied loading. Finally, this damage evolution is used for a simulation to predict the degradation of ITO as function in the applied load and correlate this degradation with the resistance variation. Experimental results showed that during unloading, crack closure results in recovery of conductivity and decrease in the overall resistance of the cracked ITO. Also, statistics about the crack spacing showed that the cracking pattern is not perfectly piriodical however it has a positively skewed distribution. The higher the applied load, the less the discrepancy in the crack spacing data. It was found that the cracking mechanism of ITO starts with transverse cracking with local delamination at the crack tip unlike the mechanism proposed in the literature of having only cracking pattern without any local delamination. This is the actual mechanism that leads to the high increase in ITO resistance. The analytical code simulates the damage evolution in the ITO layer as function in the applied strain. This will be extended further to correlate the damage to the resistance variation in following studies.
Negative Bias Temperature Stress Reliability in Trench-Gated P-Channel Power MOSFETs

In this paper, we present the results of an experimental analysis of the degradation induced by negative-bias temperature stress (NBTS) in trench-gated p-channel power MOSFETs. Threshold voltage and carrier mobility are affected by hole trapping in bulk oxide and interface-state generation due to oxide electric field effects. A fast recovery phase occurs when gate bias is removed or reduced in order to measure the threshold voltage. Hence, various techniques for evaluating threshold voltage shift are adopted in order to highlight the differences in the dynamics of degradation. We investigate the influence of gate bias levels during the stress. Moreover, with the help of recovery studies, we try to distinguish the impact of interface-state generation and charge trapping on the NBTS degradation.
Title Differential effects of ageing and BLS training experience on attitudetowards

Purpose of study: To determine the effects of ageing and training experience on attitude towards performing basic life support (BLS). Methods: We gave a questionnaire to attendants of the courses for BLS or safe driving in authorised driving schools. The questionnaire included questions about participants’ backgrounds. The questionnaire explored the participant's willingness to perform BLS in four hypothetical scenarios related to early emergency call, cardiopulmonary resuscitation (CPR) under their own initiative, telephone-assisted compression-only CPR and use of an automated external defibrillator (AED), respectively. Results: There were significant differences in gender, occupation, residential area, experience of BLS training, and knowledge of AED use among the young (17 29 y, N=6122), middle-aged (30 59 y, N=827) and elderly (>59 y, N=15743) groups. In all four scenarios, the proportion of respondents willing to perform BLS was lowest in the elderly group. More respondents in the elderly group were willing to follow the telephone-assisted instruction rather than performing CPR under their own initiative. Multiple logistic regression analysis confirmed ageing as an independent factor related to negative attitude in all scenarios. Gender, occupation, resident area, experience with BLS training and knowledge about AED use were other independent factors. Prior BLS training did not increase willingness to make an emergency call. Conclusion: The aged population has a more negative attitude towards performing BLS. BLS training should be modified to help the elderly gain confidence with the essential elements of BLS, including making early emergency calls.
Proton MR spectroscopy in mild cognitive impairment and Alzheimer disease: comparison of 1.5 and 3 T.

BACKGROUND AND PURPOSE Theoretically, proton ((1)H) MR spectroscopy at a higher field strength has the advantages of higher signal-to-noise ratio and improved spectral resolution. We therefore compared the ability of single-voxel (1)H MR spectroscopy at 1.5 and 3 T to diagnostically discriminate among cognitively normal elderly subjects, patients with mild cognitive impairment (MCI), and patients with Alzheimer disease (AD). METHODS At both 1.5 and 3 T, we studied 41 cognitively normal elderly subjects, 20 patients with MCI, and 20 patients with AD. In each subject, (1)H MR spectroscopy was performed at TEs of 30 and 135 ms and from voxels placed over the posterior cingulate gyri. RESULTS Average line widths and interexamination variability of metabolite ratios were higher at 3 T than at 1.5 T. Consistent quantification of glutamine (Gln) + glutamate/creatine (Cr) and Gln/Cr peak ratios occurred at 3 T but not at 1.5 T. Choline (Cho)/Cr (at TE = 135 ms) and myo-inositol (MI)/Cr were higher and N-acetylaspartate (NAA)/Cr (at TE = 135 ms) and NAA/MI were lower in patients with MCI than in cognitively normal subjects only at 1.5 T. MI/Cr and Cho/Cr were higher and NAA/Cr and NAA/MI were lower in patients with AD than in cognitively normal subjects at both 1.5 and 3 T. Differentiation of patients with AD from cognitively normal subjects by using the NAA/MI data was similar at both field strengths (P >.05). CONCLUSION With currently available technology, the diagnostic performance of (1)H MR spectroscopy in patients with MCI and those with AD was not better at 3 T than at 1.5 T.
