Published: October 2020

This paper presents the experimental and analytical results of the contribution of carbon fibre reinforced polymer (CFRP) laminates to the shear strength of RC beams. To assess the efficiency of the carbon fibre reinforced polymer (CFRP) laminates on the strengthened specimens, twelve identical beams of cross-sectional dimensions 150x150x750mm were cast, out of which three are un-strengthened and nine were strengthened with U-wrap strips at 100 mm away from each support at varying CFRP laminates layers of single, double and triple amounts. The prepared specimens were subjected to a three-point bending test. The results obtained revealed that the CFRP laminate increased the shear strength of the strengthened specimens over the control (un-strengthened) by 35.06%, 54.40% and 69.30% for single, double and triple layers of CFRP laminate respectively. The experimental results was also compared with the analytical results obtained based on the equation proposed by Khalifa et al., 1998. The analytical results obtained from the equation closely agreed with the experimental results. Therefore, it implies that the CFRP has the potentials of strengthening shear defiant RC beams.

The incidence of multi-drug resistance (MDR) in bacteria has become a major problem in this era of modern medicine, making it necessary to look for other options that can be used to treat the infections caused by the MDR bacteria. Scientifically, one of the therapies that is now looking promising, is application of phage therapy. This research work was designed to determine the efficacy of coliphages isolated from sewage, against MDR clinical isolates of E. coli. Ten (10) clinical isolates were subjected to both microbiological conventional and PCR techniques for confirmation, thereafter, the confirmed isolates were tested against some 8 commonly used antibiotics using disk diffusion method to identify the MDR among them. The MDR isolates were subjected to various dilutions (1:10-1:108) of coliphage recovered from sewage, sampled from 5 different locations and isolated by using double agar overlay method. Out of the 10 isolates collected, 8(80%) were confirmed as E. coli, all (8/8: 100%) of which were MDR. However, 6(75%) out of the 8 MDR E. coli, were lysed by the coliphages-observed as cytopathic effect in form of clear zones (plaques) within the bacterial lawn and were recorded from all the dilutions (100%) tested and from all the locations (100%) sampled. Conclusively, infection by MDR E. coli may be life threatening, as it is highly prevalent (100% in our study). However, the coliphages were found to be abundant in sewage and the application of their therapy may provide a good alternative treatment against the MDR.

The study examined the factors responsible for change in vegetation cover between 1999 and 2019. Decadal data for climatic variable (rainfall and temperature), Landsat satellite images and population data of 1999, 2009 and 2019 were used. Land use/Land cover Change Detection, linear time series and Spearman rank order correlation analysis were used. The results revealed that the extent change between (1999-2009) and (2009-2019) for built-up, vegetation and bare surface were; (+91.66, +276.41), (-4.06, -40.42) and (-27.44, -23.5) respectively. There were increasing trends in the built-up environment, population growth and rainfall at the rate of (19.3 km2 per-10), (110116 persons per-10) and (231.5mm per-10) respectively. There were decrease trend of temperature and vegetation cover at the rate of (-1.15oC per-10) and (-19.3 km2 per-10) respectively. Negative relationship exist between population growth (r = -0.938), built up (r = -0.987), rainfall (r = -0.982) and vegetation cover, while positive relationship exist between temperature (r = 0.965) and vegetation cover. The study conclude that temperature is the major factor influencing the loss in vegetation cover, rapid population growth and urban expansion were experienced during the study period. The study recommend five (5) trees should be planted per built-up structure in order to create more carbon sink and to improve vegetal resource which were affected by human activities and changing climatic variables

Published: October 2020

The aim of this work is to present a precise numerical calculus method capable to predict the behavior of a wind turbine mast, which is characterized by an open door in its lower part in order to facilitate the access to maintenance tasks. A parametric study had been conducted in this context. The structure studied of steel tower is considered a thin cylindrical shell with constant section and thickness along its studied height. The geometry of the tower had been modeled by non-linear shell type elements. Designers use interior reinforcements to avoid local buckling and minimize the disturbance of the distribution of stress in extreme conditions. The designs adopted in the models are proposed to achieve optimized results, the minimization of the mass, the maximization of the natural frequency and the rigidity at the end of the work. Many configuration had been considered in this study, the enhancement of the gap by using a panel with variable thickness value, by longitudinal stiffeners, by combined stiffeners and finally by a stiffened panel. A numerical model had been suggested to examine a cylindrical shell behavior in compression using the Abaqus software. The obtained results demonstrate the viability and performance of the proposed approach which perfectly meets the structural requirements of the wind tower. We have observed that the stiff plate model gives reliable results to stability under extreme load. On the other hand it is economically profitable is less material needed for manufacturing, which reduces the cost.

Published: October 2020

Terahertz (THz) absorption spectra of poly 3-hydroxyalkanoates (PHB) for different conformations were investigated using molecular dynamics (MD) method. Temperature-dependent THz absorption spectra of PHB were measured over a temperature range of 10 K to 200 K. Peaks around (2.4-2.6THz) and (3.1-3.2THz) were observed due to vibrational transition of PHB, 1stpeaks are polarized perpendicular to c(┴)axis (along a, b axis) and next peaks are oriented parallel to the c(//) axis. The peak around (2.4-2.6THz) was assigned due to vibrational transition of PHB and C-H…O=C hydrogen bonds are oriented perpendicular to the c(┴) axis. We have also investigated orientation of the intermolecular hydrogen bonds by MD simulation and confirmed that it was mainly along the b axis of PHB. THz absorption spectra shifted to the lower frequencies and noticed widening of the absorption peaks that visualized from characteristics of peaks within creasing temperature, which is well reproduce of experimental observation.

Permasalahan menyusui umumnya menjadi penyebab dihentikannya pemberian ASI (AirSusu Ibu), durasi pemberian ASI menjadi lebih singkat dan secara dini dilakukan upaya untuk menggantikanatau memberikan suplementasi menggunakan susu formula atau Makanan Pendamping ASI (MPASI). Berdasarkan studi terdahulu, pendidikan kesehatan yang dilakukan dengan pendekatan tertentu ternyata mampu meningkatkan pengetahuan, kemampuan menyusui dan kepercayaan diri ibu dalam memberikan ASI pada bayi. Penelitian ini bertujuan untuk mengetahui perbedaan pengaruh dari dilakukannya konseling dan penyuluhan mengenai permasalahan menyusui yang dilakukan saat trimester akhir kehamilan terhadap pengetahuan, motivasi, dan kemampuan menyusui selama satu bulan pertama pasca persalinan.Metode: Penelitian dilakukan di wilayah kerja Puskesmas Mojolangu dan Puskesmas Kendalkerep mulai darikurun waktu Desember 2013 – April 2014. Rancangan penelitian yang dipakai adalah penelitian eksperimental dengan membagi sampel ke dalam dua kelompok perlakuan, yaitu kelompok yang mendapatkan konseling melalui kunjungan rumah dan kelompok penyuluhan yang terdiri dari masing-masing jumlah responden 23 orang. Penelitian melakukan penilaian hasil kuesioner pretest dan posttest mengenai pengetahuan dan motivasi menyusui serta pengamatan/observasi langsung kemampuan menyusuinya dengan praktik menyusui. Analisis data dilakukan dengan uji t-test dan uji Mann-Whitney (univariat dan bivariat), serta analisis multivariat menggunakan ANCOVA (Analysis of Covariance).Hasil: Hasil penelitian menunjukkan bahwa baik konseling maupun penyuluhan mengenai permasalahan menyusui yang diberikan pada trimester akhir kehamilan secara signifikan mampu meningkatkan pengetahuan menyusui selama satu bulan pertama pasca persalinan dengan nilai p = 0,000 (p < 0,05). Namun, jika dibandingkan antara konseling dan penyuluhan maka diantara keduanya tidak ada perbedaan yang bermakna. Sedangkan terkait motivasi menyusui dan kemampuan menyusui tidak didapatkan perbedaan pengaruh pada kedua kelompok perlakuan secara signifikan. Walaupun dari hasil rerata nilai, tampak bahwa rerata nilai motivasi dan observasi kemampuan menyusui pada kelompok konseling lebih baik daripada kelompok penyuluhan.

ABSTRACT
The purpose of this paper is to evaluate the validity and reliability of Cognitive Therapy Intervention (CTI) which focusing on the resilience of adolescents with behavioural problems. CTI is developed based on Cognitive Theory and the Sidek Module Development Model. The CTI has eight interventions. The CTI manuscript was distributed to five content experts to determine intervention’s validity. The finding shows that the validity index 0.87 was obtained. Meanwhile, thirty two adolescents were selected to measure the reliability of each intervention by evaluating the objectives in each intervention session. As a result, the reliability index 0.85 was obtained. From these two indexes, the Cognitive Therapy Intervention (CTI) possesses high validity and good reliability, and is ready to use. The intervention implies the counselling intervention in working resilience of adolescents with behavioural behaviour. This CTI is recommended to be used by school counsellor to handle adolescents with behavioural problems.

Background
Optimal induction for patients without pretransplant donor-specific antibodies (DSAs) is poorly defined. The goal of this study was to compare the incidence of de novo DSA (dnDSA) and graft outcomes between induction therapies in patients with a negative virtual crossmatch (VXM).

Methods
A retrospective chart review was performed, identifying 782 patients with a negative VXM who underwent kidney transplantation at a single, high-volume institution between January 2013 and May 2017. Kaplan–Meier analysis was used to assess the incidence of dnDSA and allograft survival between induction therapies in this group. dnDSA is defined as the development of new post-transplant DSA, at any MFI level.

Results
Induction therapy included alemtuzumab (N=87, 11%), basiliximab (N=522, 67%), and anti-thymocyte globulin (ATG; N=173, 22%). One-year graft survival was similar between groups (alemtuzumab, 100%; basiliximab, 98%; ATG, 99%). Incidence of acute rejection at 1 year was <2% and not different between the three groups. Alemtuzumab was associated with the highest incidence of dnDSA at 14%, compared with 5% and 8% in basiliximab and ATG groups, respectively, at 1 year (P=0.009). In multivariate regression analyses, alemtuzumab retained its significant association with a dnDSA HR of 2.5 (95% CI, 1.51 to 4.25; P=0.0004).

Conclusions
In summary, alemtuzumab was associated with a higher rate of dnDSA development in patients with a negative VXM; however, this finding was not associated with rejection or graft failure.

Os planossolos das Terras Baixas do Rio Grande do Sul caracterizam-se por apresentar horizonte A superficial e horizonte B com capacidade de percolação muito baixa, o que provoca longos períodos de encharcamento após chuvas e prejudica o desenvolvimento e a produtividade da soja. Para evitar esses problemas, são necessários sistemas de drenagem adequados e o aprimoramento de sistemas de preparo do solo e de cultivo que proporcionem faixas mais secas na lavoura. O presente trabalho tem por objetivo determinar o arranjo espacial de plantas e o sistema de cultivo de soja mais adequado para as Terras Baixas do Rio Grande do Sul. Dois experimentos foram conduzidos na Estação Experimental Terras Baixas da Embrapa Clima Temperado, em Capão do Leão/RS. O primeiro deles (safra 2016/17) diferenciou o potencial produtivo de cultivares indicadas para terras baixas, sendo a cultivar BMX Icone RR a mais produtiva, com 4073 kg ha?1 de grãos enquanto outras 10 cultivares produziram em média 3021 kg ha?1. No segundo experimento (safra 2018/19), a cultivar BMX Icone foi adotada. Foram avaliados 2 manejos de solo (preparo convencional e preparo com sulco/camalhão) e 3 arranjos de plantas (230, 330 e 430 mil plantas ha?1). Foram avaliadas a altura de plantas; altura de inserção da primeira vagem; nº de ramificações da haste principal; peso de grãos; número de grãos e vagens por planta; e produtividade de grãos. O sulco-camalhão com 330 mil plantas ha?1 com espaçamento entrelinhas 35 / 60 cm, propiciou melhor desempenho geral da cultura e melhor produtividade.

O presente trabalho foi aplicado ao Estudo de Capacidade de Suporte de Carga do corpo receptor Ressaca para assimilar o efluente gerado por uma indústria alimentícia situada na Região Metropolitana de Curitiba. Os parâmetros físico-químicos avaliados foram: pH, oxigênio dissolvido (OD), demanda química de oxigênio (DQO), demanda bioquímica de oxigênio (DBO5) e temperatura do efluente e do corpo receptor. Os dados obtidos foram utilizados para aplicação no Modelo Matemático de Qualidade da Água proposto pelos estudiosos Streeter e Phelps (1925) e também para a análise de atendimento à legislação vigente. Através da aplicação do modelo, foi verificado que o rio não pertence à classe estipulada pela resolução CONAMA 357 e que não está apresentando capacidade de autodepuração após o lançamento do efluente, mesmo este estando dentro dos padrões exigidos por legislação. Foram apontadas duas causas para o mesmo já possuir elevada concentração de matéria orgânica: provável ocorrência de lançamentos clandestinos e falta de saneamento na região à qual o estudo foi aplicado. Diante disso, foi destacada a necessidade de um novo e eficiente Plano de Gerenciamento da Bacia do Alto Iguaçu e também foram sugeridas melhorias na estação de tratamento de efluentes da indústria para redução da DBO do efluente tratado.

Os processos de produção de laticínios são conhecidos por um grande consumo de água. No processo de produção de leite UHT, leite condensado e leite em pó é gerada uma grande quantidade de “águas evaporadas”. Essas águas possuem pequena carga orgânica (em torno de 40 mg/L de Demanda Química de Oxigênio – DQO) e outros compostos em pequenas quantidades, que impedem o reaproveitamento direto. Levando em conta o desenvolvimento sustentável e a escassez da água, surge a ideia de reaproveitar a água evaporada. O objetivo do trabalho é obter uma água com qualidade para reúso através do processo de osmose inversa e adsorção e comparar análises físico-químicas com padrões de potabilidade, para um possível reaproveitamento desta água. Os resultados mostraram que a combinação de osmose inversa e carvão ativado removeram a matéria orgânica da água para 1 mg/L de O2, e o carvão ativado removeu odores residuais na água, possibilitando o seu reuso industrial.
