Control of Anthracnose Disease (Colletotrichum Gloeosporioides) Using Nano Chitosan Hydrolyzed by Chitinase Derived From Burkholderia Cepacia Isolate E76

Anthracnose (Colletotrichum gloeosporioides) is one of the important diseases of fruit crops that need to be controlled. This study was aimed to obtain the best formula of hydrolyzed nano chitosan and its potensial in controlling anthracnose. The hydrolyzed chitosan was prepared using chitinase enzyme extracted from Burkholderia cepacia isolate E76. Chitosan nanoparticles were synthesized using ionic gelation method by reacting hydrolyzed chitosan (0.2%) with Sodium tripolyphosphate (STPP) (0.1%) as cross-linking agent using 30–60 minutes stirring condition. The bioactivity of the nano chitosan formula was tested to C. gloeosporioides under in vitro and in vivo assays. The specific enzymatic activity of the purified chitinase was higher (0.19 U/mg) than that of crude enzyme (supernatant) with the purity increased by 3.8 times. Of the four formula tested, Formula A (hydrolyzed chitosan to STPP volume ratio of 5 : 1 with 60 minutes stirring condition) was found good in terms of physical characteristic of the particle. The formula nano chitosan particle had the spherical-like shape with an average particle size of 126.2+3.8 nm, polydispersity index (PI) of 0.4+0.02, and zeta potential (ZP) value of 27.8+0.2 mV. Nano chitosan had an inhibitory activity to C. gloeosporioides in vitro up to 85.7%. Moreover, it could inhibit 61.2% of C. gloeosporioides spores germination. It was shown that nano chitosan was also effective to reduce anthracnose disease severity in vivo when applied as a preventive measure on Chili and papaya fruits. This study could be used as a reference for further fruit coating application using nano chitosan as a promising postharvest biocontrol agent to C. gloeosporioides

Prospect of Using Bacterial Bio-formulation to Suppress Bacterial Leaf Blight of Rice: a Case Study in Cianjur, West Java

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is a major disease of rice in Indonesia which remains difficult to be controled. A number of bacterial isolates had been collected and screened for their ability to antagonize Xoo disease. Six isolates with the highest antagonistic potential and wide spectrum were chosen for studies based on their ability to control the disease. Bio-formulations consisted of single or mixtures (consortium) of the bacterial antagonists were formulated and tested for their effectiveness to control BLB under field trials in Cianjur, West Java. Efficacy of the bio-formulations against the disease on different rice cultivars varied significantly with HDB reductions ranging from 10.5% to 29.4% among the cultivars tested in the WS 2010/2011. The mixture of A6 + A8-bentonite showed a good ability to reduce BB infestation by up to 25%. Performance of the A6+A8-bentonite formulation also exceeded those of the individual isolate formulations, such as Burkholderia spp. E76-bentonite and S. marcescens SKM-kaolin. Application of the bacterial mixture formulation did not affect significantly on rice plant height, number of tillers, and weight of 1000 grains, but increased grain yield up to 8%. This study showed that the advantages of single or mixed cultures were apparent and further evaluation for application of bio-formulation need to be done under more intensive field conditions

Chemically deposited magnesium hydroxide thin film

Here we report for the first time to the best of our knowledge the processing techniques, nucleation kinetics and the nanoindentation behaviour of a 1.5 mu m magnesium hydroxide thin film chemically deposited on a commercially available soda lime silica glass substrate at room temperature. The phase and microstructure of the films were analysed by X-ray diffraction, scanning electron microscopy, field emission scanning electron microscopy as well as transmission electron microscopy. An exponential nucleation kinetics was identified for the growth of the thin films. The nanomechanical properties, e. g. nanohardness and Young's modulus of the films were measured by the nanoindentation technique at ultralow loads of 50, 70 and 100 mu N. Finally, the nature of deformation of the thin film was analysed in terms of the energetics of the nanoindentation process and the microstructure

Connectomic markers of disease expression, genetic risk and resilience in bipolar disorder.

Bipolar disorder (BD) is characterized by emotional dysregulation and cognitive deficits associated with abnormal connectivity between subcortical-primarily emotional processing regions-and prefrontal regulatory areas. Given the significant contribution of genetic factors to BD, studies in unaffected first-degree relatives can identify neural mechanisms of genetic risk but also resilience, thus paving the way for preventive interventions. Dynamic causal modeling (DCM) and random-effects Bayesian model selection were used to define and assess connectomic phenotypes linked to facial affect processing and working memory in a demographically matched sample of first-degree relatives carefully selected for resilience (n=25), euthymic patients with BD (n=41) and unrelated healthy controls (n=46). During facial affect processing, patients and relatives showed similarly increased frontolimbic connectivity; resilient relatives, however, evidenced additional adaptive hyperconnectivity within the ventral visual stream. During working memory processing, patients displayed widespread hypoconnectivity within the corresponding network. In contrast, working memory network connectivity in resilient relatives was comparable to that of controls. Our results indicate that frontolimbic dysfunction during affect processing could represent a marker of genetic risk to BD, and diffuse hypoconnectivity within the working memory network a marker of disease expression. The association of hyperconnectivity within the affect-processing network with resilience to BD suggests adaptive plasticity that allows for compensatory changes and encourages further investigation of this phenotype in genetic and early intervention studies

Perancangan Dan Analisis Statis Ban Tanpa Udara (Airless Tire) Untuk Ukuran 165/60 R12

Electric cars have large torque from the start driven or acceleration. The use of conventional tires on electric cars can accelerate tire surface wear. Airless tires can be applied to electric cars, such as those being developed by the Bridgestone and Micheline tire companies. This research was conducted to determine, predict stress, displacement, strain and safety factor values and evaluate the design results through FEA simulations of the airless tire model. The contribution to be achieved in this research is to redesign to improve the stress, displacement, strain and safety factor of the airless tire model that has been previously studied. In this study, airless tire planned with size 165/60 R12 refers to the ETRTO standard. The airless tire model is visualized using the AutoCAD and CATIA software. The FEA (Finite Element Analysis) simulation is done with SOLIDWORKS. The honeycomb structure uses polyurethane as the main honeycomb component suitable for pneumatic tire replacement. The 4 planned honeycomb models show better stress, displacement, strain and safety factors compared to the comparative airless tire model previously examined
