Effects of grazing and understorey clearing on regeneration of a valonia oak silvopastoral system in Western Greece

Valonia oak (Quercus ithaburensis subsp. macrolepis) forms traditional silvopastoral systems in Greece and other eastern Mediterranean countries. In a meeting that was organized under the framework of the AGFORWARD (FP7) research project, local stakeholders of the Xeromero area (Western Greece), where valonia oak forms such agroforestry systems, expressed their concerns for the low regeneration of the oaks, and attributed the problem to the livestock overgrazing and the overgrowth of the woody understorey. To test this hypothesis, an experiment was organized in the particular area. Specifically, four sheep and goat sheds as well as the pathways that the livestock follow daily for grazing were identified and 6 paired plots, 5X8 meters in size each, were established per shed territory, a total of 24 plots. In each pair, one plot was fenced and the other plot was left free to grazing. Woody understorey vegetation was cleared in half of each plot in early autumn of the first growing season. Data were collected twice per year (May and October) and included number of seedlings and young samplings, acorns and acorn-cups as well as the floristic characteristics. A twoyears results show that understorey clearing did not have any significant effects on two variables measured while fencing significantly increased the number of seedlings and young saplings as well the number of acorns only in
Screening, Isolation, Identification and Antibiogram Study of Enterobacteriaceae in Ready to Cook, Chilled Food Products in Tiruchirappalli, India

The present study was concentrated to screen some members in Enterobacteriaceae family from chilled meat products procured from different retail shops in Tiruchirappalli, Tamilnadu. A total of six varieties of ready to cook chilled food products with five samples in each were randomly purchased from departmental stores, retailer meat shops and local vendors of Tiruchirappalli. Out of 30 ready to cook, chilled food products screened for the presence of Enterobacteriaceae, 28 found to be positive for Enterobacteriaceae. A total of 36 bacterial strains were selected at random and identified. Only 11 isolates were finally confirmed as Enterobacteriaceae and this was shared by Escherichia coli (E. coli), Citrobacter spp. , Salmonella spp. , Serratia spp. and Proteus spp. Among these Proteus spp. (23.3%) was found predominant in all the samples. Antibiogram study revealed that 54.5% isolates were susceptible to each of Ofloxacin and Ciprofloxacin followed by Ampicillin (45.5%), Chloramphenicol (27.3%) and Gentamycin (18.2%). A high percentage of 54.5% isolates were found to be multidrug resistance (resistant to 3 or more antibiotics). E. coli and Proteus spp. isolated from mixed vegetables and beef respectively, were exhibited 100% resistant to Penicillin, Ciprofloxacin, Chloramphenicol, Ofloxacin, Ampicillin and Gentamycin. The study revealed poor sanitation and cross-contamination in food processing area which resulted in the enhancement of enteropathogenic bacteria which are, known to cause foodborne illnesses. Also, the multidrug resistance noticed in the present study may be linked to the use of antibiotics in cattle rearing which constitute a serious threat to public health.
Using Ginger Extract for Synthesis of Metallic Nanoparticles and their Applications in Water Treatment

the chemical and physical methods for nanoparticle production are relatively expensive and complicated, let alone their toxicity for the ecosystem. On the contrary, using ginger to reduce metal ions into nanoparticles is a more easier and rapid technique, as ginger contains reducing agents; e.g., alkaloids, and phenolic compounds. We synthesized Silver, Copper and Nickel nanoparticles using ginger extract and characterized them by Transmission Electron micrograph, X-ray diffraction, and UV-Vis spectrophotometer. Different concentrations of Silver, Copper and Nickel nanoparticles (100, 200, 300, 400,500 mg/ml) were tested on some chemicals and the microbial content of two water samples [(Brackish lake (Mariout), El Kilo 21 lake)] Alexandria. We concluded that the addition of 100 μl of copper, 50 μl of silver, and 150 μl of Nickel nanoparticles / 50 ml of the water sample removed the total content of nitrate and phosphate efficiently, whereas 30 μl of copper, 30 μl of silver and 75 μl of Nickel nanoparticle / 50 ml of the water sample totally inhibited bacterial contamination. This demonstrates that the preparation of Silver, Copper and Nickel nanoparticles using ginger extract is a safe, easy and economic technique, in addition to being effective in water decontamination and environmental applications.
2 The network and its upcoming challenges

Many optimization problems admit a number of local optima, among which there is the global optimum. For these problems, various heuristic optimization methods have been proposed. Comparing the results of these solvers requires the definition of suitable metrics. In the electrical energy systems literature, simple metrics such as best value obtained, the mean value, the median or the standard deviation of the solutions are still used. However, the comparisons carried out with these metrics are rather weak, and on these bases a somehow uncontrolled proliferation of heuristic solvers is taking place. This paper addresses the overall issue of understanding the reasons of this proliferation, showing that the assessment of the best solver can be cast into a perpetual motion scheme. Moreover, this paper shows how the use of more refined metrics defined to compare the optimization result, associated with the definition of appropriate benchmarks, may make the comparisons among the solvers more robust. The proposed metrics are based on the concept of first‐order stochastic dominance and are defined for the cases in which: (i) the globally optimal solution can be found (for testing purposes); and (ii) the number of possible solutions is so large that practically it cannot be guaranteed that the global optimum has been found. Illustrative examples are provided for a typical problem in the electrical energy systems area – distribution network reconfiguration. The conceptual results obtained are generally valid to compare the results of other optimization problems.

A 20 Year Record of Satellite-Derived Winds over the Polar Regions for Climate Studies

Recent studies have shown that the Arctic climate has changed markedly over the past 25 years. Unfortunately, two major reanalysis products that can be used for studying recent changes exhibit relatively large errors in the wind field over the Arctic where there is little radiosonde data available for assimilation. At least ten numerical weather prediction centers worldwide have demonstrated that satellite-derived polar winds have a positive impact on global weather forecasts. The impact on reanalyses should be similar. Therefore, a polar wind data set spanning more than 20 years was generated using Advanced Very High Resolution Radiometer (AVHRR) data. This paper focuses on the winds generated over the Arctic. Comparisons with winds from collocated radiosondes show good agreement over the Arctic, with relatively small biases in the AVHRR-derived winds of 0.1 – 0.8 m s, depending on the level. In addition, AVHRR polar winds have lower speed root-mean-squared errors and speed biases than reanalysis winds when compared to rawinsondes that were not assimilated into the reanalysis. We also show that frequently the AVHRR winds are faster in jet streams than what the reanalysis depicts. The results from this study could lead to a better dynamical understanding of the deficiencies on the reanalysis products over the Arctic region. It is recommended that the historical AVHRR polar winds dataset be included in future reanalysis efforts.
14 C distribution in lemon plants

Summary14 C distribution patterns were studied on small potted trees under glasshouse conditions by supplying 14 CO2 to selected source leaves for 24 hours and then preparing autoradiographs of the entire shoots. Experiments covered the period from the emergence of new growth, through flowering and fruit-set, up to the stage of fruit maturity.Newly emerged growth drew 14 C assimilates from both current photosynthesis and stored substrate. Developing leaves represented strong sinks and did not become contributing organs until fully mature. Flowers also represented uniformly strong sinks for assimilates although after fruit-set some discrimination existed between adjacent fruitlets with respect to their ability to import assimilates. The developing fruit continued to act as sinks for assimilates up to the time of harvest.14 C assimilate turnover in mature leaves following a brief exposure to 14 CO2 was sluggish, despite the presence of developing shoots in the leaf axils. The removal of 14 C photosynthate w.
Movinder: A Movie Recommendation System for Groups

Using the wealth of data available on user preferences, researchers and online streaming companies have extensively researched and deployed movie recommender systems. Most recommendation algorithms process the preferences of each user, and potentially those of other similar users, to predict other movies they might like. However, watching movies is often a social activity shared by multiple actors, such as a group of friends. The social dimension of watching movies contradicts common approaches that strive to satisfy one user at a time. In this project, we analyse different implementations of a movie recommender system that aims to maximize the collective satisfaction of a group of users. Using the combination of Movielens and IMDb datasets, we simulate the group of friends to train our recommender models. The recommender models implemented and discussed include the following types of networks: Neural Collaborative Filtering (NCF), Neural Graph Collaborative Filtering (NGCF), Siamese Neural Network (SNN) and LightFM models. The obtained results are compared. The fastest models are deployed to the website, whereas other models with higher accuracy can be found in the notebooks due to higher computation time.

Green Cities — Good For the Soul ? Landscape and Health

These words, penned over a hundred and fifty five years ago by the American poet Walt Whitman, articulate what we all intuitively know, that nature is good for us. But is it universally important, and do some individuals respond more positively than others, and if so, why? Can poorer communities—rural and urban—truly benefit from green space? In this article, we address these basic yet fundamental questions, and illustrate some of the recent and far-reaching innovative research from the United Kingdom (UK) and around the globe which supports the view.
VERIFICATION OF MCD19A2 DATA AND STUDY OF AEROSOL CHARACTERISTICS IN BEIJING-TIANJIN-HEBEI REGION

Abstract. The atmospheric aerosol pollution in the Beijing-Tianjin-Hebei(BTH) region of China is particularly serious. To quickly and accurately evaluate the aerosol pollution in BTH region using the remote sensing method – this article verified the accuracy of the global 1km resolution MCD19A2 aerosol optical depth (AOD) product to clarify its reliability in BTH region, moreover, MCD19A2 was used to study the characteristics of aerosols and its correlation with air quality index (AQI). First, the AOD spatial distribution in BTH region from 2014 to 2018 was obtained through the processes of MCD19A2 such as format conversion, mosaic. Then the AOD results were verified with AERONET measured data through accurate space-time matching, proving the high accuracy and reliability of MCD19A2 (R = 0.9504, MAE = 0.0863, RMSE = 0.1243, EE = 82.26%). Besides, based on the AOD results at different scales, the spatiotemporal characteristics of aerosols in BTH region were analyzed from the aspects of spatial distribution, annual variation, and seasonal variation. Finally, the study shows that MCD19A2 AOD and AQI have a high correlation and similar spatiotemporal characteristics, proving the direct indication of MCD19A2 on air pollution. This article plays an important role in the research of aerosol characteristics, air pollution monitoring and so on.
Habitat Characteristics of Active and Abandoned Red-Cockaded Woodpecker Colonies

Active red-cockaded wood- pecker (Picoides borealis) colonies in the Piedmont of Georgia are mature pine stands (mean age = 87 f 1 yr old) with relatively sparse midstories (mean basal area = 31 2 3 f2lac). Active and aban- doned colony sites have similar overstory characteristics, but midstories are signifi- cantly denser in abandoned colony sites (mean basal area = 56 k 3 f? /ac). Pre- vious studies have focused on the effect of hardwoods in the midstory, but we found that increases in both pine and hardwood midstory density are associated with colony abandonment. A logistic regression model based on field data suggests that the prob- ability of a colony becoming abandoned in- creases considerably when midstory basal area is >30 fflac. To maintain red- cockaded woodpecker populations, manag- ers should keep midstory basal area in col- onies below 25 f? lac. Treatments should be applied to entire stands and not just around individual cavity trees.
Bayesian Estimation and Economic Analysis of Under-Replicated Field Trials With a Linear Response Plateau Function

The linear response with plateau (LRP) is widely used in agronomic and agricultural economic studies of crop yield response. This empirical example uses data from an under-replicated experiment to compare maize (Zea maize L.) yield response to nitrogen under different plant and corridor row spacing. Not all replications received a 0-nitrogen rate, making estimation of the LRP difficult because data for the intercept terms is absent. We leverage information from other treatments using Bayesian methods to estimate the yield response of each treatment using a LRP function, given limited replication and absence of check plots for some treatments. We use a linearized LRP, which bypasses using the “min” operator typically required to estimate LRP functions. Economically optimal nitrogen rates were determined and net returns from treatments compared from the perspective of risk-averse producers. The wide plant/narrow row treatment was most profitable when the decision rule was to apply nitrogen. The statistical procedure used here may be useful for exploratory analyses of pilot agronomic trials that may include unbalanced and under-replicated treatments.
DYNAMIC SYNCHRONIZATION MECHANISM AND REACTIVE CURRENT SUPPORT OF PMSG BASED WIND FARM DURING SEVERE GRID FAULT

Grid specifications require wind farm to stay on-grid and inject specific reactive current when grid fault occurs. To suit the necessities, reactive power devices for instance the static synchronous compensators (STATCOM) are used in current wind farms. Therefore to produce reactive currents, the wind energy conversion system (WECS) and the STATCOM are usually controlled with the phase locked loop (PLL)-oriented vector control methods. The wind farm has the danger of losing synchronization with the grid under extreme fault conditions on the account of dynamic power inequality between generation and consumption. This paper examine the dynamic synchronization mechanism and stability criteria of the wind farm and intend a coordinated current control method for the WECS and the STATCOM during extreme grid fault. Subsequently the synchronization stability of both WECS and the STATCOM is kept in presence by the dynamic power control of the wind farm. The control motive of the generatorand grid-side converters for the WECS is swap to evade the interface between the dc-link voltage control loop and the synchronization loop. The synchronized STATCOM generate additional reactive currents to help the wind farm meet the necessities of the grid specifications. Hence the theoretical analyses and proposed control method are verified by simulations.

amorphous-Si-H solar cells

Absorption of amorphous-Si hydrogenated (aSi-H) solar cells can be enhanced by using dielectric nanostructures made of Si⁠ 3N⁠ 4 that work like antireflection coatings. The analysis focus on the short-circuit current delivered by the cell under solar irradiance, and it is made taking into account every layer and structure of an aSi-H cell. A customized design of the antireflection coating in the form of nanostructured dielectric layers, produces a short-circuit current enhancement of 15.2% with respect to the reference flat solar cell, and a lower reflectivity of the cell. Three different geometries of linear nanostructures have been analyzed and compared with quite similar results among them. An improvement in performance has been also obtained for realizable geometrical dimensions that could be fabricated while maintaining electric conductivity of the front contact.

Molecular dissection of telomere dysfunction and analysis of G-overhangs in Arabidopsis thaliana

Molecular Dissection of Telomere Dysfunction and Analysis of G-overhangs in Arabidopsis thaliana. (December 2007) Michelle L. Heacock, B.S., Delta State University Chair of Advisory Committee: Dr. Dorothy E. Shippen Telomeres comprise the physical ends of chromosomes. In the absence of telomerase, the enzyme responsible for replenishing telomeric DNA, telomeres progressively shorten due to the end replication problem. Eventually telomeres reach a length where they are recruited into end-to-end chromosome fusions. Through the use of novel PCR strategies, I followed the fate of telomeres in plants lacking telomerase as they progressed into dysfunction. I uncovered two distinct structural/functional length transitions. The first transition (~1 kb) marks the onset of telomere dysfunction, where telomeres are transiently uncapped and a subset of them engage in end-to-end fusions. The second transition (~300 bp) defines complete telomere dysfunction as telomeres below this length lack G-overhangs and the vast majority of the chromosome ends fuse. Thus, these two telomere lengths define architectural transitions that link structure and function. In addition, I uncovered a hierarchy of end-joining pathways that join dysfunctional telomeres in which the non-homologous end-joining (NHEJ) protein, KU predominates. In the absence of KU, telomeres are joined by a microhomologymediated end-joining pathway (MMEJ) that is dependent on Mre11. I also show that
A Comparative Analysis of Asymmetric (BaTiO3) 1−xΛ/(BaZrO3)xΛ Superlattices via X-Ray Diffraction and Raman Spectroscopy

This work is aimed at studying asymmetric ((BT) /(BZ) ) superlattices, grown by pulsed laser deposition onto (001) MgO substrates. The thicknesses of BT (ferroelectric) and BZ (paraelectric) layers were varied so that х ranged from 0 to 1 at a modulation period of about 80 A. The films were 400 nm thick. The out-of-plane lattice parameters of constituents were assessed using X-ray diffraction. The lattice dynamic peculiarities of superlattices were probed via Raman spectroscopy; special attention is paid to the analysis of E(1TO) and A1(2TO) ferroelectric soft modes. A comparative analysis of data acquired via both experimental techniques reveals the enhancement of stress between BT and BZ layers with a decrease in symmetry from the tetragonal to a monoclinic phase due to strains induced by the lattice parameter mismatch between the constituents.
