Soil Phosphorus Dynamics of Wheat-Based Cropping Systems in the Semiarid Region of Argentina

The dynamics of soil P forms and particle size fractions was studied under three wheat-based cropping sequences in production systems of Argentina. The whole soil and its coarse (100–2000 µm) and fine (0–100 µm) fractions were analyzed to determine Bray-Kurtz extractable (Pe), organic (Po), inorganic (Pi), and total (Pte) phosphorus. The reference soil was determined at time 0 and compared to a four-year period (time 9 to 12) in three crop sequences: wheat (Triticum aestivum L.)-cattle grazing on natural grasses (WG), continuous wheat (WW), and wheat-legume (WL). Levels of Pe showed differences over time, from 10 to 16 µg g−1 in WG, in line with agriculture and cattle grazing alternate sequences. In WW, P level increased with time, while in WL systems a significant decrease in P from 33.7 to 10.4 µg P g−1 was found during the legume period. Soil P values varied between reference soil and soil samples in year nine and between treatments. Pi was significantly lower in WW, and its concentration increased with time. The coarse fraction of the reference plots had significantly higher levels of Po and Pi than the cultivated treatments, probably a consequence of the particulate organic matter decomposition and coarse mineral particle weathering. The observed changes in Pi content could be attributed to differences in occluded P equilibrium under different soil environments (mainly pH) and crop-tillage-climatic interaction.
TUZ at TRECVID 2015: Video Hyperlinking Task

—In this paper, we present our video hyperlinking systems for the TRECVID 2015 Video Hyperlinking Task [1]. We used the provided BBC Dataset video keyframes and subtitles to develop two different systems and submit two separate runs. Our ﬁrst run (tv15lnk TUZ L 1 F M M MERGE1) uses subtitles to discover possible semantic links between video segments. Our second run (tv15lnk TUZ L 1 F M M MERGE2) follows a different approach and uses only visual sentences extracted from keyframes to discover visual links between video segments. When we compare our two different approaches w.r. t. their MAP scores, subtitle based linking performs better. This is probably due to the fact that speech text contains more robust semantic data then visual sentences. We were planning to use both the ﬁrst and the second systems to get a better result but our third system was not ready in time for submission. Overall results of the TRECVID 2015 Video Hyperlinking Task shows that our subtitle based ﬁrst system is placed at the third quartile (%50%75) among all participants whereas our visual sentence based second system is placed at the fourth quartile /%75%100). We are planning to further our work by merging our two systems and discovering more interlinks between BBC Dataset videos.
DEVELOPMENT AND VALIDATION OF STABILITY-INDICATING HPTLC METHOD FOR DETERMINATION OF DOLASETRON MESYLATE

Objective: To develop and validate stability indicating HPTLC method for determination of Dolasetron mesylate. Methods: The chromatographic separation was performed on aluminium plates precoated with silica gel 60 F 254 using Methanol: Choloroform: Ethyl acetate (7:2:1 v/v/v) as mobile phase followed by densitometric scanning at 280 nm. Results: The chromatographic condition gave a compact spot for Dolasetron mesylate at Rf value of 0.65±0.03. Stress testing was performed in accordance with international conference on harmonization (ICH) Q1A R2 guidelines. Method was validated as per ICH Q2 R1 guidelines. The calibration curve was found to be linear in the concentration range of 100-800 ng/band for Dolasetron mesylate. The limit of detection and quantification was found to2.24 ng/band and 6.79 ng/band, respectively. Conclusion: A new sensitive, simple, and stability indicating high performance thin layer chromatographic (HPTLC) method has been developed and validated for determination of Dolastron mesylate. The proposed method can be used for routine determination of Dolasetron mesylate stability.
[Lawyers in a Blocked Society] Career Expectations and Professional Success in the Italian Legal Labour Market

This article focuses on the changing conditions of Italian lawyers, starting from the widespread idea here assumed as a general hypothesis of the law profession that, in many cases, could be a way out for people with unfulfilled career expectations. In detail, a brief introduction situates the increase in the number of lawyers in the context of an economy with a low capacity to create high-education jobs, while the first section highlights the segmentation of the legal labour market. The second section then examines the relationship between initial career expectations and professional success, also paying attention to social origins as a determinant of success or failure. Furthermore, it attempts to typify and understand different choice patterns. For these purposes, the author presents selected findings of a study on lawyers based in Florence.
CAULFIELD, FRANCIS DONALD. Electromechanical Actuator Development for Integrated Chatter Prediction on High Speed Machining

CAULFIELD, FRANCIS DONALD. Electromechanical Actuator Development for Integrated Chatter Prediction on High Speed Machining Centers. (Under the direction of Gregory Dale Buckner) Machine tool chatter imposes limitations on the productivity and quality of modern high speed machining (HSM) operations. It has been shown that chatter prediction and avoidance strategies can lead to increased machining productivity if certain modal characteristics of the machine are known. The objectives of this research are to design and demonstrate an electromechanical actuator (EMA) to easily and accurately identify these characteristics. Design specifications for this actuator reflect a wide range of machine tools and operating conditions. A simulation-based design strategy is employed, based on traditional electromechanical analysis, finite element analysis (FEA), and computer simulations to ensure performance meets the design specifications. A prototype EMA system is built to validate the analytical results and demonstrate its capabilities as part of an automated chatter prediction and avoidance system. The EMA is shown to generate the required modal characteristics, namely frequency response functions (FRFs) and stability lobe diagrams (SLDs) quickly, accurately, and with fewer technical skill requirements than other vibration testing methods. Experimental machining tests demonstrate that the EMA can be an effective component of an integrated chatter prediction and avoidance system.
How overdrying wood reduces its bonding to phenol-formaldehyde adhesives : a critical review of the literature. Part II, Chemical reactions

Literature dealing with the effect of excessive drying (overdrying) on wood surface inactivation to bonding is reviewed in two parts and critically evaluated, primarily for phenolic adhesives. Part I of the review, published earlier, covers physical mechanisms that could contribute to surface inactivation. The principal physical mechanism is the migration to the surface of extractives that decrease wettability. Part II of the review considers mechanisms involving chemical reactions: reduction of wood surface strength, oxidation and pyrolysis of wood bonding sites, and chemical interference with resin cure or bonding. In those cases where extractives are not the primary cause of inactivation, oxidation or pyrolysis probably is the major cause of inactivation. Inactivation of oak and of some Southeast Asian hardwoods may be due to the acidity of extractives, but the importance of decreased wettability caused by extractives cannot be dismissed.
Continuous decision making in optimal reservoir operation using DP-ANN

According to desirable usage of water resources and because of large amount of existence dam in the world especially in Iran, optimum operation of these reservoirs and suitable operation rules is unavoidable. To achieve this goal and because of efficiency of Artificial Neural Networks (ANNs) in forecasting, this model was used to derive operation rules of reservoirs. In this paper, the amount of release in each period was calculated according to the storage of reservoir and the amount of inflow in the same period. We implied this methodology to Dez dam in west-south of Iran. The results were compared with regression model. Results show the high accuracy in this field of water resource management.
Security Issues in Helper Data Systems

The security of traditional security primitives depend largely on their sensitivity to minute variations in input. However in several important applications, especially in recent times, the input is inherently noisy. The increasing prominence of such applications has generated a lot of research in the development and optimisation of systems that can achieve adequate security with noisy inputs. In this thesis we present an in-depth study of security with noisy data, especially with regards to its effective combination with cryptography. We focus on improving the functionality and security of one of such applications achieving robust security with noisy data, the helper data system. In particular, we identify potential areas of threats and vulnerabilities in various components of the helper data system and advise on ways to prevent and minimise the associated risks.
Comparing Tea Leaf Products and Other Forages for In-vitro Degradability, Fermentation, and Methane for Their Potential Use as Natural Additives for Ruminants

Tea leaves are a rich source of plant secondary metabolites such as tannins and saponins that have the potential to manipulate rumen fermentation and to lessen methane (CH 4 ) production.Samples of green tea (GTL), black tea (BTL), their spent leaves after water extraction (SGTL and SBTL), ryegrass hay (RH), ryegrass silage (RS), paddy straws (PS), barley straws (BS), and wheat straws (WS) were compared for their rumen in-vitro organic matter degradability (IVOMD, g/kg DM), pH, ammonia (NH 3 , mg/L), total volatile fatty acids (tVFA, mmol/L), total gas production (tGP, L/kg OM), and methane output (CH 4 ,L/kg OM) after 28h incubation with buffered rumen fluid under anaerobic conditions at 39 o C in glass syringes. One-way ANOVA on Minitab 16 was used to examine differences between products at P<0.05 for four replicate samples. There were no differences between tea leaf products, RH and RS but the straws tended to have lower IVOMD compared with tea leaf products and other forages. GTL produced the lowest NH 3 followed by BTL, SGTL, SBTL, and other forages. There were no differences between most tea leaf products, RH, RS, and the straws for tVFA concentration but PS and WS produced the lowest tVFA. GTL, SGTL, and RH had higher tGP than BTL, SBTL, and the straws but they had a lower tGP than RS. GTL, BTL, and SBTL produced similar levels of CH 4 as the straws but this was less than RS and SGTL. The results suggest that if tea leaf products are included in the straw-based diets as natural feed additives, they may improve degradability, tVFA, NH 3 ,and tGP production without increasing CH 4 output. Low NH 3 production for tea leaf products could be the sign of more by-pass protein to be absorbed in small intestine. Keywords: Tea leafproducts, in-vitro measurements, and ruminants.
Human navigation assistance with a RGB-D sensor

This paper focuses on the creation of a human navigation assistance prototype. The system uses a conventional RGB-D camera and a laptop to analyze the environment surrounding the user and provides him with enough information for a safe navigation. The system is designed to work indoors and performs two main tasks: floor and obstacle detection and staircase detection. Both tasks make use of the range and visual information captured by the sensor. The camera points downwards, allowing to acquire relevant navigation information without invading the privacy of other people. The system has been tested in real environments showing good results in the detection of obstacles and staircase.
JOINT NOISE CANCELLATION/DETECTION FOR A TOWED ARRAY IN A HOSTILE ENVIRONMENT

Tow ship noise is a major problem plaguing the detection, classification, localization and tracking problems. It is a major contributor to towed array measurement uncertainties that can lead to large estimation errors in any form of signal processing problem aimed at extracting the weak target information. Many sonar-processing approaches ignore this problem relying on narrowband techniques to remove these undesirable interferences at the cost of precious signal-to-noise ratio (SNR). In this paper we address the idea of noise cancellation by formulating it in terms of a joint cancellation/detection problem. It is shown that the joint processor can be designed to perform in a broadband processing environment.
Predictors of superstitious beliefs

This study investigated whether relationships exist among personal control, coping mechanism, primary control, secondary control and superstitious beliefs. The participants were 375 Ghanaian student athletes (females = 44%). They completed measures of self-reported superstitious beliefs, personal control, coping mechanisms, primary and secondary control strategies. The data were analysed to evaluate the correlates of both positive and negative superstitious beliefs and how constructs of personal control, coping mechanisms and control strategies, predict positive and negative superstitious beliefs. The results indicated that personal control, coping mechanisms and control strategies were predictors of negative and positive superstitious beliefs. In the final model exaggerated internal control, God-mediated control, emotional support, and substance use were predictors of negative superstitions. Exaggerated internal control, substance use, emotional support and acceptance were predictors of positive superstitions. Athletes may activate different types of superstitious beliefs to cope and gain control in situations of uncertainty.
Toward a new understanding of Syntrichia submontana (Pottiaceae, Bryophyta)

Syntrichia submontana (Broth.) Ochyra has been previously reported from Tajikistan, Kyrgyzstan and Mongolia. It was considered to be dioicous, with sporophytes unknown. Our study of extensive herbarium collections from Mongolia, southern Siberia and the Caucasus, as well as some collections from China revealed that this species has a much wider distribution in Asia. Its sexual condition is polyoicous: autoicous plants are most frequent, with antheridia and paraphyses lacking perigonial leaves, forming a group just below the perichaetium, but occasionally also male, female and, more rarely, synoicous plants are found in the same tuft. Mature sporophytes are rare in Mongolian collections, but they are frequent in China, southern Siberia and the Caucasus. Peristomial basal membrane is very low, consisting of 1-2(-3) cell rows. S. submontana is similar in gametophytic characters to S. sinensis (Müll. Hal.) Ochyra, and their close relationship was confirmed by molecular study (nrITS2). A description of S. submontana is amended and supplemented by sporophyte characteristics. Syntrichia longimucronata (X.J. Li) R.H. Zander is synonymized with S. submontana. Descriptions, illustrations, distribution and ecological data are provided for S. submontana and S. sinensis. Our molecular data also found two distinct entities within the morphologically variable S. laevipila Brid. , which tentatively confirms recognizing of S. pagorum Milde as a separate species. Specimens of S. caninervis var. astrakhanica Ignatov, Ignatova & Suragina from distant localities are also resolved in a clade separated from S. caninervis var. caninervis; thus the variety likely deserves being raised to the species level.
SQL Injection Detection and Prevention Using Input Filter Technique

SQL injection attacks, a class of injection flaw in which specially crafted input strings leads to illegal queries to databases, are one of the topmost threats to web applications. A number of research prototypes and commercial products that maintain the queries structure in web applications have been developed. But these techniques either fail to address the full scope of the problem or have limitations. Based on our observation that the injected string in a SQL injection attack is interpreted differently on different databases, in this paper, we propose a novel and effective solution to solve this problem. It has been proposed to detect various types of SQLIA. This method checks the attribute value for single quote, double dash and space provided by the user through the input fields. When attacker is making SQL injection he should probably use a space, single quotes or double dashes in his input. Depending on the no of space, double dash and single quote the count value of the input field (having default count as1) will get increased by 1 respectively. The fixed count value and the dynamically generated count value of the input parameters are then compared. If both the count values are same, there is no SQLIA and if they vary that means some SQL code has been injected through the input fields. Finally such attempt will be recorded separately and will be blocked to access the database.
A Confirmatory Analysis of Zakah Compliance Behavioural Intention on Employment Income

A confirmatory test of Ajzen and Fishbein’s (1980) theory of reasoned action using structural equation modeling was carried out to study the impact of zakah compliance intention toward employment income. This study had two objectives: 1) to examine the reliability and validity of all variables in the theory of reasoned action using confirmatory factor analysis (CFA), and 2) to determine the relationship between each variable of attitude and subjective norm (obtained from CFA) with zakah compliance intention on employment income. Based on 264 respondents, we used CFA structural equation modeling as the measurement model in measuring attitude, subjective norm, and intention. This study used decomposition of variable in the theory of reasoned action to analyse zakah compliance intention of zakah on employment income. The results of the study indicated that the goodness of fit model comprising attitude, subjective norm, and intention is better when CFA was used. Three components of attitude and two components of subjective norm constructs were found to achieve unidimensionality, and convergent validity and discriminant validity. Thus, this study supported the argument that attitude and subjective norm in the model of zakah on employment income compose of several components and provide good reliability and validity if each component is tested with CFA. Additionally, this study also supported the relationship between attitude and subjective norm with zakah compliance behavioural intention. Recommendations for practice and limitations of the study are also discussed.
Change does not happen overnight: a case study on stream macroinvertebrates

The influence of day/night conditions on individual animal/plant species has been widely studied, but diel cycle studies of the entire stream macroinvertebrate community are extremely rare. This study explored potential dissimilarities between daytime and nighttime macroinvertebrate assemblages by extensive fieldwork conducted in the Lemme stream, a natural water course of NW Italy. Here numerous structural and functional metrics (richness, abundance, biomass, indicator taxa, composition, biomonitoring values and feeding groups) were evaluated at the family level. Small-scale environmental variables were investigated to understand possible differences between macroinvertebrate assemblages in the daytime/nighttime. After collecting and identifying 21 459 organisms of 50 taxa, Chironomidae (Diptera) was the most abundant under both day and night conditions. Our findings stressed that similar results and biological information on daytime/nighttime data were obtained. No marked differences could be related to various factors: heterotrophic condition of small-order streams, presence of aquatic predators under night and day conditions, absence of taxa with a specific phototaxis. Of all the environmental variables, velocity was always the most important in both situations, with some differences detected in the importance of the second variable (riverbed substrate diameter). This research, and future studies on different conditions and geographic areas, will contribute knowledge on stream macroinvertebrate diel activity, and provide useful information about efficient sampling strategies.
Determining plutonium mass in spent fuel with non-destructive assay techniques - NGSU research overview and update on 6 NDA techniques

This poster is one of two complementary posters. The Next Generation Safeguards Initiative (NGSI) of the U.S. DOE has initiated a multi-lab/university collaboration to quantify the plutonium (Pu) mass in, and detect the diversion of pins from, spent nuclear fuel assemblies with non-destructive assay (NDA). This research effort has the goal of quantifying the capability of 14 NDA techniques as well as training a future generation of safeguards practitioners. By November of 2010, we will be 1.5 years into the first phase (2.5 years) of work. This first phase involves primarily Monte Carlo modelling while the second phase (also 2.5 years) will focus on experimental work. The goal of phase one is to quantify the detection capability of the various techniques for the benefit of safeguard technology developers, regulators, and policy makers as well as to determine what integrated techniques merit experimental work, We are considering a wide range of possible technologies since our research horizon is longer term than the focus of most regulator bodies. The capability of all of the NDA techniques will be determined for a library of 64 17 x 17 PWR assemblies [burnups (15, 30, 45, 60 GWd/tU), initial enrichments (2, 3, 4, 5%) andmore » cooling times (1, 5, 20, 80 years)]. The burnup and cooling time were simulated with each fuel pin being comprised of four radial regions. In this paper an overview of the purpose will be given as well as a technical update on the following 6 neutron techniques: {sup 252}Cf Interrogation with Prompt Neutron Detection, Delayed Neutrons, Differential Die-Away, Differential Die-Away Self-Interrogation, Passive Neutron Albedo Reactivity, Self-Integration Neutron Resonance Densitometry. The technical update will quantify the anticipated performance of each technique for the 64 assemblies of the spent fuel library. « less
Intra-industry trade and economic distance: causality tests using panel data

In this paper, we implement Granger causalty tests using panel data as methodology perfected by Hurlin (2004, 2005) and Hurlin and Venet(2004). We consider the bilateral trade patterns of the European Union with 17 countries over the period 1976-2000. We show that for the whole sample, there are no-causal relationship whatever the lag considered. However, we find some causal relationship from the economic distance to the share of intra-industry trade in the sub-sample of emerging countries and the inverse relationship in the sub-sample of developing countries.
