USO DO FINO DE CARVÃO VEGETAL E DA ADUBAÇÃO POTÁSSICA NA PRODUÇÃO DE BERINJELA (Solanum melongena L.) EM LATOSSOLO AMARELO ANTRÓPICO DA AMAZÔNIA CENTRAL

Na Amazonia, a maioria dos solos de terra firme apresenta boas caracteristicas fisicas e baixa fertilidade quimica natural. Nessas areas, destaca-se a ocorrencia de manchas de solos com horizonte superficial de cor escura, denominada Terra Preta, com elevados niveis de fertilidade, sendo por isso, utilizados para a exploracao agricola de forma ampla e intensa. Apesar disso, observa-se que estes solos apresentam uma reducao de sua fertilidade natural apos anos de intensa utilizacao agricola, que afeta, principalmente, a disponibilidade de potassio. Dessa forma, torna-se necessario buscar alternativas de manejo da fertilidade desses solos. Nesse sentido, dado a alta disponibilidade de residuos de carvao na regiao, foi conduzido este trabalho envolvendo doses de carvao e de potassio com o objetivo de avaliar os efeitos da adicao do fino de carvao vegetal (residuo) e de cloreto de potassio sobre a disponibilidade de nutrientes no solo, estado nutricional e na produtividade de berinjela (Solanum melongena L.). O experimento foi conduzido em Latossolo Amarelo com A Antropico localizado no km 30 da Rodovia AM 070, no Ramal da Serra Baixa, Municipio de Iranduba AM, com coordenadas geograficas 03o 30 S e 60o 20 W. O delineamento experimental utilizado foi em blocos ao caso, em esquema fatorial 5x3, com quatro repeticoes, onde o primeiro fator testado foi o potassio aplicado como KCl nas doses de 0, 125, 250, 375, 500 kg ha-1 e o segundo fator o carvao nas quantidades de 0, 5, 10 ton ha- 1. Antes e depois do ensaio foram coletadas amostras de solos das camadas de 0 - 20 cm e 20 - 40 cm de profundidade para analise da fertilidade. Na epoca da floracao foram coletadas amostras de folhas para determinacao da concentracao de nutrientes. A cultivar de berinjela utilizada foi a Cica. De forma isolada, as doses de KCl aumentaram o pH e os teores de K+, Mg++ e o Mn do solo, e tambem afetaram positivamente os teores foliares de Ca, Mg e K, porem reduzindo os de Zn e de Mn. Enquanto isso, o carvao afetou negativamente os teores de Mg++ no solo e de Ca e Mg nas folhas. Houve interacao entre os fatores de adubacao em relacao as variaveis concentracao foliar de Mg, K e P e produtividade que, por sua vez teve resposta a adubacao potassica de tendencia quadratica crescente ate a dose de 301 kg ha-1 de KCl. Os melhores lucros foram obtidos com 375 kg ha-1 de KCl (Relacao Beneficio/Custo = 5,79) e com a combinacao de 250 kg de KCl ha-1 e 10 ton de carvao ha-1 (Relacao Beneficio/Custo = 5,69).
A Secure Methodology to Detect and Prevent Ddos and Sql Injection Attacks

As most of the applications host on cloud, Security is a major concern for the data owners. The cloud environment has to be secure and protect data owner data from cloud attacks. In this project work, we study about securing firewall against client side attacks namely Denial of firewall and SQL injection attacks. Denial of firewall is nothing but overloading the firewall by bursting n number of requests through vulnerable scripts. SQL injection attack is defined as bypassing the security protocols by malicious scripts. Thus we proposed to design and develop a web application to detect and prevent denial of firewall and SQL injection attacks. The denial of firewall attack can be performed using Java environment based servers and prevention can be performed using Digital Signature Algorithm (DSA) in which filter based approach and software puzzle based approach are performed to detect the malicious script based requests. Once the Deep Packet Inspection (DPI): filter based approach and software puzzle based approach are find satisfactory only the request would be processed. If the request is find malicious automatically the requested IP address would be blocked. Various type of SQL injection attacks namely SQL login bypass, Blind injection, SQL sleep attack, Data fetching attack are analysed and performed. The SQL injection attack can be prevented using PREPARE statements. This statements are created to make the SQL queries more efficient and render security benefits. This statement provides effective prevention mechanism against SQL injection attacks. Thus our proposed solution, provides high security against firewall attacks namely denial of firewall and SQL injection securing the data owner files and preventing compromising of firewall.
Role of social media in academic achievement among Northern Border University sudents

The study aimed to measure the impact of social media on academic achievement among a sample of Northern Border University students in the Kingdom of Saudi Arabia. The study seeks to reach a cognitive perception to recognize the effect of using social media on academic achievement in university students. It relied upon the quantitative and qualitative distribution of each type of social media application among students to determine the importance of social media informing study groups amongst themselves and with faculty members. This helped to identify the negative and positive effects of using social media applications on the process of academic achievement among Northern Border University students. To achieve those objectives, the researchers used the descriptive survey methodology, with the questionnaire used as a study tool. The most prominent results showed that a wide range of students at the University is highly interested in using social media in academic achievement and in communicating with the Faculty members. The study also concluded with a proposal to increase the activation of social media as an important tool for increasing the rate of academic achievement among Northern Border University students.
Produção de filmes ativos a base de amido e zeólita modificada com prata

Um dos desafios da industria de embalagens e a producao de filmes que utilizem como materia-prima biopolimeros que sejam ao mesmo tempo biodegradaveis e derivados de fonte renovavel. Neste contexto, o amido se destaca como potencial materia-prima devido a sua abundância e baixo custo. Para manter a qualidade microbiologica e sensorial dos alimentos, a tendencia atual inclui o desenvolvimento de embalagens que alem de atuarem como uma barreira a agentes externos, tambem interagem com o alimento desempenhando um papel ativo na sua conservacao. O objetivo deste trabalho foi produzir filmes ativos biodegradaveis de amido de mandioca adicionados de zeolita Clinoptilolita modificada com prata e avaliar as propriedades mecânicas, a permeabilidade ao vapor de agua (PVA) e a atividade antibacteriana. A adicao de zeolita modificada com prata conferiu aos filmes maior rigidez, diminuiu a elongacao na ruptura, reduziu a hidrofilicidade a partir da reducao dos valores de PVA e proporcionou atividade antimicrobiana contra Staphylococcus aureus e Escherichia coli. A modificacao da zeolita com prata nao causou alteracoes significativas em sua estrutura morfologica, pois os filmes contendo as mesmas concentracoes de zeolita nao modificada apresentaram propriedades mecânicas e PVA similares. Com este trabalho concluiu-se que o uso da zeolita modificada com prata na concentracao de 0,1 % foi mais viavel, pois os filmes apresentaram atividade antimicrobiana, alem de a zeolita ter atuado como agente de reforco da matriz de amido e ter auxiliado na reducao da PVA.
Newly Qualified Female Teachers’ Perception of Teaching Practicum as a Component of Initial Teacher Education in South Africa

This study was undertaken with the aim of understanding how newly qualified female teachers perceive teaching practicum in the South African context. Teaching Practicum is a vital component of the initial teacher education (ITE) programme because it enriches future teachers’ knowledge, skills and abilities towards a lifelong career in the teaching profession. Teachers make valuable contributions to the growth of any nation as they help produce future leaders. It is therefore necessary to have a competent teaching workforce to improve pass rates as well as reduce dropout rates among learners. The study took the qualitative deductive premise making use of semi-structured interviews to collect data from more than 30 novice teachers. Key words, which helped in the identification of themes, were distilled from the responses. A core overall finding of the study point to a mix of experiences - benefits and shortcomings - which not only affect the development of prospective teachers but also have profound implications for both policy enhancement and implementation. Regarding policy enhancement and implementation, it is suggested that universities and schools where novice teachers are posted for teaching practice should have good relations for support advancements. In this case, it is advised that the novice teachers should be exposed to critical mentoring opportunities to allow for clearer understanding of the real classroom scope. This study believes that for this to be fruitful, schools should among others be well-equipped. Suggestions for further research are also flagged.
Design and Implementation of Multiplexed and Obfuscated Physical Unclonable Function

Model building attack on Physical Unclonable Functions (PUFs) by using machine learning (ML) techniques has been a focus in the PUF research area. PUF is a hardware security primitive which can extract unique hardware characteristics (i.e., device-specific) by exploiting the intrinsic manufacturing process variations during integrated circuit (IC) fabrication. The nature of the manufacturing process variations which is random and complex makes a PUF realistically and physically impossible to clone atom-by-atom. Nevertheless, its function is vulnerable to model-building attacks by using ML techniques. Arbiter-PUF is one of the earliest proposed delay-based PUFs which is vulnerable to ML-attack. In the past, several techniques have been proposed to increase its resiliency, but often has to sacrifice the reproducibility of the Arbiter-PUF response. In this paper, we propose a new derivative of Arbiter-PUF which is called Mixed Arbiter-PUF (MA-PUF). Four Arbiter-PUFs are combined and their outputs are multiplexed to generate the final response. We show that MA-PUF has good properties of uniqueness, reliability, and uniformity. Moreover, the resilient of MA-PUF against ML-attack is 15% better than a conventional Arbiter-PUF. The predictability of MA-PUF close to 65% could be achieved when combining with challenge permutation technique.
Empathy impairs virtue: the influence of empathy and vulnerability on charitable giving

PurposeOnline charitable giving is prevalent, and how to attract individuals' attention to donate is essential for charities. Little is known about the interaction effect of empathy (donor) and vulnerability (receiver) on donate intention. To bridge this gap, this study aims to investigate whether the influence of empathy on charitable giving would be moderated by receivers' vulnerability, and if yes, what is the mechanism.Design/methodology/approachFive experiments were conducted in the context of charitable giving with 1,303 participants to test our hypotheses.FindingsWhen empathetic individuals confronted high vulnerable receivers, they were less likely to donate; otherwise, they were more likely to donate when they confronted low vulnerable receivers, and this interaction effect was mediated by concern about self.Originality/valueThe present research identifies a novel moderator of the effect of empathy on charitable giving and elucidates the underlying mechanism of concern about self. Based on these findings, the authors provide actionable implications for charities by demonstrating the interaction effect of empathy and vulnerability on donate intention.
Obesity and Skin Problems in Persons With a Lower Limb Amputation: An Observational Study

Background: A lower limb amputation can lead to weight gain and obesity. However, data regarding the prevalence of obesity in the Dutch population with a lower limb amputation are lacking. Furthermore, the impact of obesity on skin problems of the residual limb and the need of prosthetic repairs is unknown. The aim of this study was to determine the prevalence of obesity in Dutch persons with a lower limb amputation and to investigate the relationship between body weight, body mass index and skin problems of the residual limb and the frequency of prosthetic repairs. Methods: A survey was performed among adults with a unilateral lower limb amputation due to any cause, and who are user of a prosthesis. The survey consisted of measurement of the subjects’ body height and weight, a questionnaire which assessed self-reported skin problems in the previous month and factors potentially associated with these skin problems, and assessment of the frequency of visits to the orthopedic workshop. Results: In total, 413 persons were enrolled. Of them, 39% (95% confidence interval 35%−44%) was overweight and 28% (95% confidence interval 24%−33%) was obese. A total of 77% (95% confidence interval 73%−81%) reported one or more skin problems in the past month. Body weight and body mass index were neither associated with the presence of skin problems in general nor with the number of prosthetic repairs. Persons with severe skin problems had a slightly lower body mass index (26.6 kg/m2 vs. 28.0 kg/m2, p = 0.012). Persons with skin problems were younger than those without (difference in means 6.0 years (95% confidence interval 3.0−8.9)). Conclusion: Our findings show that obesity is common in the ambulant population with a lower limb amputation, with a prevalence being higher than in the general Dutch adult population. However, its negative impact on the presence of skin problems and the frequency of prosthetic repairs may be limited.
Electronic structure of nickel nano-structures on titanium dioxide and copper : photoemission study

It is very critical in the subject of surface science to discriminate the initial- and final-state effects in photoemission of supported (or isolated) metal clusters. In this thesis, Auger parameter analysis is applied to separate the contributions of the initial- and final-state effect to the binding energy shift observed. The comparison made on TiO2(001) and TiO2(110) surfaces demonstrates the importance of substrate contributions to the initial-state effect. The further analysis helps us to assign initial-state effect to a combination of eigenvalue shift in surface core-level shift and charge transfer between the Ni clusters and the TiO2 substrates. The cluster size effect and interfacial charge transfer have a collective impact on the electronic structure of Ni clusters on the TiO2 surfaces. The variation of the triplet atomic states in Ni satellite features can be used to trace the electron transfer mechanism when the dimension of Ni nano-clusters is modified because the Ni 3d electron population varies with scaling the dimension size. The correlation enhancement of electrons in Ni nano-clusters due to the confinement in reduced dimension has been observed. Both the size and shape of nano-clusters show strong influence on the Ni 2p satellite structures. Apart from the 6-eV satellite, a 3-eV satellite structure emerges in Ni 2p3/2 photoemission spectra for small clusters due to the existence of 3E and 3T triplet states. However, the 3-eV satellite becomes weakened in larger clusters due to the increased electron population in 3d level, which is achieved through the electron transfer from the free-electron-like 4sp states to the unhybridized pure 3d spin down states.
Application of active learning algorithm in handwriting recognition numbers

Active learning is very suitable for many problems in natural language processing, where unlabeled data may be abundant, but annotation is slow and expensive. This article aims to illustrate some active learning methods for handwritten digit recognition tasks, such as the least confidence and entropy methods. We investigated the previously used sequence model query selection strategies and used some selection strategies for sample labeling in handwritten digit recognition. We also conduct a large-scale empirical comparison of using multiple corpora, which shows that our proposed method improves the technical level.
Cost-utility analysis of olanzapine in four-drug antiemetic therapy in Japanese patients treated with highly emetogenic cisplatin-containing chemotherapy

Purpose Olanzapine has been shown to have an additive effect on the three-drug antiemetic therapy, consisting of aprepitant, palonosetron, and dexamethasone, in a highly emetogenic cisplatin-containing chemotherapy. Although olanzapine may be more economical than aprepitant or palonosetron, an adequate cost-efficacy analysis has not been conducted. We conducted a cost-utility analysis to evaluate the cost-effectiveness of olanzapine in four-drug antiemetic therapy among Japanese patients.Methods We simulated model patients treated with highly emetogenic cisplatin-containing chemotherapy and developed a decision-analytical model of patients receiving triple antiemetic therapy with or without olanzapine. The cost, probabilities, and incremental cost-effectiveness ratio (ICER) of each treatment were calculated from the perspective of the Japanese healthcare payer. The threshold ICER was set at 45,867 United States dollars (USD) (5 million Japanese yen) per quality-adjusted life-year (QALY). The probabilities, utility value, and other costs were obtained from published sources. The robustness of this model was validated by one-way sensitivity analysis and probabilistic sensitivity analysis.Results The calculated ICER was 5,156 USD/QALY, which was below the threshold. Under the set conditions, the probabilistic sensitivity analysis revealed a 100% probability that olanzapine was cost-effective. Based on the one-way sensitivity analysis, reducing the cost of olanzapine below 10.78 USD placed the ICER below the threshold. Conclusion Olanzapine was cost-effective in the four-drug antiemetic therapy for Japanese patients treated with highly emetogenic cisplatin-containing chemotherapy
Polydioxanone Sutures Instead of Polypropylene Sutures for Abdominal Closure to Prevent Wound Sinuses

Due to its ability to perceive the problems, developing the appropriate reasons for that and to establish optimal solutions for it, artificial intelligence can act as a great aid in addressing the diseases of crops. The paper presents a brief overview of the application of artificial intelligence in agriculture, its available techniques for agriculture and highlights the various methods available for the detection of diseases in crops
Influence of personality traits on users’ viewing behaviour

Different views on the role of personal factors in moderating individual viewing behaviour exist. This study examined the impact of personality traits on individual viewing behaviour of facial stimulus. A total of 96 students (46 males and 50 females, age 23–28 years) were participated in this study. The Big-Five personality traits of all the participants together with data related to their eye-movements were collected and analysed. The results showed three groups of users who scored high on the personality traits of neuroticism, agreeableness and conscientiousness. Individuals who scored high in a specific personality trait were more probably to interpret the visual image differently from individuals with other personality traits. To determine the extent to which a specific personality trait is associated with users’ viewing behaviour of visual stimulus, a predictive model was developed and validated. The prediction results showed that 96.73% of the identified personality traits can potentially be predicted by the viewing behaviour of users. The findings of this study can expand the current understanding of human personality and choice behaviour. The study also contributes to the perceptual encoding process of faces and the perceptual mechanism in the holistic face processing theory.
A Compact Dual Notch Frequency Reconfigurable Antenna for WIMAX,DSRC, RADAR and Ku band Communication Applications

A frequency reconfigurable ultra-wide band antenna with dual notch bands is proposed in this paper. PIN diodes are located on ultra-wide band monopole antenna and are investigated for frequency reconfigurable characteristic of the proposed antenna. Multi-bands and narrow bands have been achieved by different combinations. Proposed antenna is fabricated on FR-4 substrate of dimensions 37 x 40 x 0.8mm. For the successful combinations, antenna performance parameters like S11 characteristics, surface current distribution, peak gain, radiation efficiency and 2D radiation patterns are analyzed and illustrated in the paper. Peak gain of 4.83dB is obtained in operating band for D1, D2= 0, 1 combination. Radiation efficiency is not less than 70% in the entire operating bands. Results are analyzed experimentally for validating proposed antenna. Simulation based results and measured results are in
