Irrigation and Nutrient Management for Crop Production: Maize (Zea mais) Performance, Resource Use Efficiency and Temporal Variability of Some Soil Properties

Information on soil health and nutrient management is crucial for recommending appropriate management practices for effective crop production and optimum yield. This study evaluated the effect of drip irrigation and fertilizer application on soil hydro-physical properties, performance and resource use of maize ( Zea mais ) in southwestern Nigeria. The experiment was a two factorial laid out in randomized complete block design (RCBD) and three replications. Irrigation treatment constituted the main factor namely: 100% (full irrigation), 75%, 50% and 35% of crop water requirement designated as 1.0I E ; 0.75I E ; 0.5I E and 0.35I E , respectively while the sub-plot was N-fertilization as N 0 - no fertilizer application and N 100 –100 kg Urea ha -1 . The highest evaporation from the soil surface was obtained from the treatment that received full irrigation. At harvest, irrigation regimes and fertilizer rates significantly increased bulk density (BD) and soil water content (SWC) while saturated hydraulic conductivity (Ksat) decreased. The highest grain yield (3.5 tons ha -1 ) was obtained under full application of crop water requirement, about 28% greater than the yield obtained from water deficit (0.35I E ) treatment. Nitrogen application of N 100 gave higher grain yield compared to no fertilizer application. The interaction between drip irrigation and N-fertilization was significant on growth parameters, yield and water use efficiency (WUE) of maize. The study showed that soil hydro-physical properties were significantly influenced by drip irrigation while the combination of full irrigation water application (1.0I E ) and adequate N-fertilization (100 kg N ha -1 ) is the best option for optimum maize performance and resource use efficiency. Keywords: Crop evapotranspiration, irrigation scheduling, soil hydro-physical properties, crop performance, resource use efficiency.
Are lung adenocarcinoma mutations shaping the immune microenvironment?

Recently, Biton et al . published in Clinical Cancer Research the article “TP53, STK11 and EGFR Mutations Predict Tumor Immune Profile and the Response to anti-PD-1 in Lung Adenocarcinoma” (1). This article points out the challenging question of the interplay between tumoral mutations in lung adenocarcinoma (localized and metastatic) and the composition of immune microenvironment.
Human Capital: Education and Health in Economic Growth and Development of the Nigerian Economy

This paper investigates the relationship between government expenditure on education and health on the growth and development of the Nigerian economy between 1977 and 2007 through the application of Augmented Dickey-Fuller techniques to examine the unit root property of the series after which cointegration test was conducted through the application of Johansen cointegration technique. The results indicate that expenditure on education and health impacted positively on economic growth and development during the period of study and a long-run relationship exists between them as confirmed by the cointegration test. The paper recommends improvement in government expenditure on human capital development (education and health), so as to boost economic growth and development.
Orientations of the Managers, Culture and Gender: Cross-cultural Study of Supervisor-Subordinate Relationship

This study investigated differences in the attitudes toward workplace practices between male and female managers from Serbia and Macedonia. There were included 200 managers, 100 managers from Macedonia and 100 managers from Serbia. The analyses is aimed at determination differences of orientations toward cultural dimensions collectivism-individualism and power distance, paternalism, and affective, instrumental, contractual and obligatory supervisor-subordinate relationship between male and female Macedonian and Serbian managers. The results suggest significant differences in orientation toward power distance and collectivism-individualism, contractual and obligatory supervisor-subordinate relationship among managers from Serbia and Macedonia. Macedonian managers score higher on collectivistic orientation, and contractual supervisor-subordinate relationship than Serbian managers. But Serbian managers score higher on orientation toward power distance and obligatory supervisor-subordinate relationship. The study showed that there are no differences according to gender and there is no interaction effect of culture and gender on orientations toward collectivism-individualism and power distance, paternalism and supervisor-subordinate relationship. The results of the study lend support for the notion that the culture influences on organizational practices. With increasing knowledge about the differences of attitudes of managers with different cultural background, increases the possibility of developing open and productive relations in the business world.
Microbial Concrete: Way to Enhance the Durability of Building Structures

Natural processes, such as weathering, faults, land subsidence, earthquakes, and human activities, create fractures and fissures in concrete structures that can reduce the service life of the structures. A novel strategy to restore or remediate such structures is biomineralization of calcium carbonate using microbes, such as those in the genus of the Bacillus species. The present study investigated the effects of Bacillus sp. CT-5, isolated from cement, on compressive strength and water-absorption tests. The results showed a 36% increase in compressive strength of cement mortar with the addition of bacterial cells. Treated cubes absorbed six times less water than control cubes as a result of microbial calcite deposition. The current work demonstrated that production of "microbial concrete" by Bacillus sp. on constructed facilities could enhance the durability of building materials.
The Potential to Learn: Pre-Service Teachers? Proposed Use of Instructional Strategies for Students with a Learning Disability.

Over recent years, moves toward the inclusion of students with special needs in mainstream classrooms has brought about increasing attention to the way general education teachers perceive these students. Commensurate with this has been a growing interest in what may constitute educational success for children with special needs in mainstream classrooms, plus the ability of general education teachers to provide effective and appropriate instruction for them. It is known that teachers form beliefs about the process of teaching during their pre-service training and also that once a belief has been held for a long time, it becomes extremely difficult to change (Bandura, 1977, and Liljedahl, 2005). With learning disabilities being one of the most common disabilities in the classroom (Clark, 1997, and Clark & Artiles, 2000), it was considered that the need to further explore pre-service teachers’ perceived use of instructional strategies in relation to students who have what is termed learning disabilities, is indeed critical. This study looked at the instructional strategies Australian pre-service teachers reported they would use for students with a learning disability compared to students without a learning disability. The findings show that pre-service teachers favour more direct teacher-centred instructional strategies for students with a learning disability and more learner-centred instructional strategies for students without a learning disability. The greatest discrepancy in strategy use between the two groups of students was the higher cognitive level instructional strategies within a learner-centred environment. Pre-service teachers would use these strategies more frequently with students who do not have a learning disability. Implications for future practice and recommendations for future research are presented.
A multi‐century perspective of variability in the Pacific Decadal Oscillation: new insights from tree rings and coral

Annual growth increments from trees and coral heads provide an opportunity to develop proxy records of North Pacific climatic variability that extend back in time well beyond the earliest instrumental records, and in regions where records have not been kept. Here we combine five published proxy records of North Pacific climatic variability in order to identify the extent to which these records provide a coherent picture of Pacific Basin climatic variability. This composite chronology is well correlated with the Pacific Decadal Oscillation (PDO) index, and provides a better record of PDO variability than any of the constituent chronologies back to 1840. A comparison of these records suggests that the PDO may not have been an important organizing structure in the North Pacific climate system over much of the 19th century, possibly indicating changes in the spatial pattern of sea‐level pressure and consequent surface climate patterns of variability over the Americas.
The Effects of Behavioral Economics on Tax Amnesty

Evaluating the economic behaviors in terms of psychology was considered as irrational at the beginning and this situation was rejected by also many economists. However, these approaches have been exposed to heavy criticism in recent years. Especially while explaining economic behaviors, the idea supporting that psychological attributes of economic agents should be taken into consideration has come forth, and dependence of economy on human psychology has been pointed out because, it doesn’t seem possible to understand the motives behind economic behaviors in general and taxational behaviors in particular. From this point of view, the aim of this study is defining the concept of economic psychology primarily and then as the research subject, investigating the effects of psychological approaches on tax amnesty.

MAYA MEMORY WORK

Abstract The critical role of social or collective memory in ongoing processes of societal reproduction and transformation is well acknowledged by anthropologists and is being increasingly modeled in archaeological interpretations as well. Investigating how social memory impacted the materialities and historical trajectories of the Maya civilization has great potential for advancing archaeological methodologies as well as enlarging our knowledge of the Maya. In addition to the wealth of epigraphic, ethnographic, and early historical information available for the Maya, archaeologists are examining enduring architecture, representative imagery, and even mundane artifacts that constitute a “technology of memory” for clues to the interplay of recollection and forgetting in the operation and transformation of Maya societies. This commentary reviews issues and problems in archaeological studies of social memory and addresses the specific prospects for investigating social memory among the pre-Hispanic Maya, drawing upon the analyses provided by the papers in this special section.
A Comparative Analysis of Unsupervised Language Adaptation Methods

To overcome the lack of annotated resources in less-resourced languages, recent approaches have been proposed to perform unsupervised language adaptation. In this paper, we explore three recent proposals: Adversarial Training, Sentence Encoder Alignment and Shared-Private Architecture. We highlight the differences of these approaches in terms of unlabeled data requirements and capability to overcome additional domain shift in the data. A comparative analysis in two different tasks is conducted, namely on Sentiment Classification and Natural Language Inference. We show that adversarial training methods are more suitable when the source and target language datasets contain other variations in content besides the language shift. Otherwise, sentence encoder alignment methods are very effective and can yield scores on the target language that are close to the source language scores.
STATISTICAL ASSESSMENT OF BIOMETRICAL SIGNS BY ELECTROCARDIOGRAPHY

В начале 2000-х годов было установлено, что в электрокардиограммах (ЭКГ) содержатся инвариантные признаки, не зависящие от физического и психоэмоционального состояния человека, позволяющие осуществлять биометрическую идентификацию личности [1, 2]. Считается, что ЭКГ практически невозможно подделать [1]. Несмотря на большие перспективы идентификации личности по ЭКГ существует ряд проблем. В частности, нет единого мнения относительно того, какие биометрические признаки лучше использовать для идентификации. Существующие на сегодняшний день методы идентификации личности по ЭКГ можно разделить на две группы: те, которые используют характерные точки ЭКГ (fiducial marks) и те, которые их не используют. К первой категории методов можно отнести подходы, использующие временные, амплитудные и морфологические особенности электрокардиосигнала, ко второй — методы, основанные на анализе автокорреляционных, фазовых и частотных свойств ЭКГ [1]. Временные признаки. Чаще всего используются временные признаки, включающие длительность различных фаз кардиоцикла (рис. 1) и временные интервалы между ними, иногда используются расстояния между R-пиками [3]. Амплитудные признаки. Ряд авторов указывает на межличностную вариабельность амплитуды пиков кардиоцикла, измеренных относительно R-пика (рис. 2) [1, 4].

Effects of menotrophin and chorulon on superovulation in Red Sokoto does

The aim of this study was to compare the efficiency of menotrophin, chorulon and their combinations in superovulation in Red Sokoto does. Fifteen healthy does weighed between 14 and 25 kg were divided into 3 groups of 5 (n=5) each. All does in the 3 groups were synchronized with CIDR for 14 days. Superovulation was performed as follows: Group 1 were treated with 37.5 IU menotrophin for three days, group 2 were treated with 500IU chorulon for 1 day and group 3 were treated with 18.75 iµ menotrophin for 3 days and 250IU chorulon for one day. The mean SEM superovulatory response in group 1, 2 and 3 was (2.6 0.92, 3.2 0.58 and 9.4 0.68) respectively. The superovulatory response showed no significant differences between group 1 and 2 however, there were statistically significance differences (p
MASTERARBEIT / MASTER’S THESIS

This master’s thesis reasons why the Target Set Selection Problem (TSSP) is of high relevance to research topics of gaining importance. The impact of graph properties on the complexity of solving the TSSP is shown. For the case of graphs with arbitrary edge weights, a novel integer linear programming formulation is established, and it is shown where the pitfalls of finding target sets in graphs with arbitrary edge weights are. For instances with different structural features, as well as for real-world data, solutions have been found and analyzed. One of the findings is, that even more than the number of nodes, a high graph density leads to a great increase in calculation time for determining the solution of the TSSP.
Technological, biochemical and microbiological characterization of fermented cassava dough use to produce cassava stick, a Gabonese traditional food

Cassava stick is a fermented food made with cassava roots and widely consumed by Gabonese populations. It manufacturing processes are made traditionally, are not often mastered and then affect the product quality. This study aims to determine various manufacturing processes of Gabonese cassava stick and appreciate physicochemical and microbiological aspects of the dough used for production. A survey was carried out among ten producers and fifteen samples were collected for the analysis. The physicochemical and microbiological parameters were determined using standards methods. Bacillus strains have been isolated, characterized biochemically and identified by PCR technique. The investigated parameters values varied from producer to another. The average values of pH, dry matter content and ash content of collected samples were respectively 4.23±0.28; 47.32±2.66 % (w/w) and 1.19±0.49 % (w/w). The total proteins and carbohydrates content were respectively 1.39±0.32 and 90.41±4.03 % (w/w) dry matter. The lipids were detected as traces in all samples. Microbiological analysis of fermented cassava dough showed average values of TMAF, Bacillus, LAB and yeast of 6.82±0.51, 5.34±0.35, 5.84±1.06 and 3.95±0.97 log CFU/g of dough respectively. The samples were not contaminated by Salmonella or Shighella. Bacillus subtilis strains known for theirs bacteriocins production were isolated on fermented cassava dough and could have an important role in spontaneous cassava fermentations considering theirs biochemical properties.
Three-receiver broadcast channel with confidential messages

The secrecy capacity region for the K-receiver degraded broadcast channel (BC) is given for confidential messages sent to the receivers and to be kept secret from an external wiretapper. Superposition coding and Wyner's random code partitioning are used to show the achievable rate tuples. Error probability analysis and equivocation calculation are also provided. In the converse proof, a new definition for the auxiliary random variables is used, which is different from either the case of the 2-receiver BC without common message or the K-receiver BC with common message, both with an external wiretapper; or the K-receiver BC without a wiretapper.
The Endotoxin-Induced NeuroinflammationModel of Parkinson ’ s Disease

Parkinson’s disease (PD) is a common neurodegenerative disorder characterized by the progressive loss of dopaminergic (DA) neurons in the substantia nigra. Although the exact cause of the dopaminergic neurodegeneration remains elusive, recent postmortem and experimental studies have revealed an essential role for neuroinflammation that is initiated and driven by activated microglial and infiltrated peripheral immune cells and their neurotoxic products (such as proinflammatory cytokines, reactive oxygen species, and nitric oxide) in the pathogenesis of PD. A bacterial endotoxin-based experimental model of PD has been established, representing a purely inflammation-driven animal model for the induction of nigrostriatal dopaminergic neurodegeneration. This model, by itself or together with genetic and toxin-based animal models, provides an important tool to delineate the precise mechanisms of neuroinflammation-mediated dopaminergic neuron loss. Here, we review the characteristics of this model and the contribution of neuroinflammatory processes, induced by the in vivo administration of bacterial endotoxin, to neurodegeneration. Furthermore, we summarize the recent experimental therapeutic strategies targeting endotoxin-induced neuroinflammation to elicit neuroprotection in the nigrostriatal dopaminergic system. The potential of the endotoxin-based PD model in the development of an early-stage specific diagnostic biomarker is also emphasized.
Determinants of User Awareness of New Information Systems - Electronic Tax Filing Perspective

Information systems literature has been stuffed with much relating to the determinants of user acceptance, adoption and diffusion through applications of variety of theories such as Theory of Reasoned Action (TRA), Theory of Planned Behavior (TPB), Innovation Diffusion Theory (IDT), Model of PC Utilization (MPCU), Technology Acceptance Model (TAM1&2) and Unified Theory of Acceptance and Use of Technology (UTAUT). The argument here is that such determinants also have their antecedents. For instance, awareness has been used as a determinant to either user intention or behavior towards acceptance, adoption or diffusion but little has been done in examining the determinants of awareness itself. This paper estimates the determinants (gender, age, education, internet experience, size and manual filing experience) of user awareness of new information systems from the perspective of electronic tax filing in Nigeria. Data was collected from the potential users in seven states in Northwestern Nigeria which was analyzed though Ordinary Least Squares regression analysis. It was found that gender, education, internet experience and manual tax filing experience are the significant determinants to user awareness of new information systems while age and size was found to be insignificant. The study contributes to the literature through focusing on an area neglected by previous researchers. It also contributes to the practice as the outcome of the study will be beneficial to policymakers in devising means for enhancing awareness of new information systems prior to actual adoption.
SULFIDE.FACIES IRON FORMATION AT THE ARCHEAN MORLEY OCCURRENCE. NORTHWESTERN ONTARIO: CONTRASTS WITH OCEANIC HYDROTHERMAL DEPOSITS

A late Archean arc-type volcanic sequence on the north shore of Lake Superior contains thin successions of sulfidefacies iron formation. One such occrrrence, the =5 m-thick Morley deposit, consists of interlayered chert, massive and laminated pyrite layers (cm scale), and carbonaceous mudstone. Pyrite laminations are up to I mm thick and generally mntain increased amounts of chert, carbon and detrital mud toward their tops. The laminations commonly are organized into upward-thinning cycles over = I cm. Discordant pyrite growth-structures on domes, together with inclined pyrite crusts and microslumps, indicate that pyrite accumulation produced an irregular microrelief on the seafloor. Pyritic and chert layers have very low trace and rare-earth-eleme\t (REE) contents. R.gE patterns of pyrite samples have small positive Eu and La anomalies relative to Archean shale, whereas the chert only has a [a anomaly. A modest hydrothermal sigual appears to be preserved in the pyritic sediments. Sulfur isotope ratios of sulfides and whole rocks from the Morley occurrence can be accounted for by hydrothermal leaching of magmatic sulfide from the host volcanic rocks, together with a component of heavier sulfur derived from the reduction of seawater sulfate. We interpret each lamination in the pyritic beds as reflecting a short-term hydrothermal injection into a stagrrant bottom layer of water. Upward-thinning cycles of laminations, indicative of gradual, but oscillatory waning of precipitation, correspond 1o medium-term hydrotlermal wents. The domal to irregular structures of the Morley pyrite provide evidence for the existence of relatively deep-water organic mats during chemical precipitation. The carbon in the pyrire laminations and associated mudstones is interpreted as a relic of this organic activity, which may have been localized around hydrothermal vents. The pyritic layers in the
