Budding of Pistacia vera L. seedling at the earlier stage of growth with a certain sex type scion is very important because P. vera vegetative growth stage is long and requires more time to produce fruit to determine the sex type of the trees. Therefore, the current experiment was carried out to determine the best time for budding current seedlings of P. vera during late summer. The budding times were 20 Aug., 1 Sept., 10 Sept., and 20 Sept in 2020, and the seedlings were between 5-6 months along budding times. The results revealed that the highest budding success (50%) was achieved from the seedlings budded on 20 September followed by those seedlings budded on 10 September (38.88%). While, budding success percentage was the lowest in the seedlings budded on 20 August and 1 September with the same ratio (27.77%). The longest shoot and the thicker shoot diameter (19.30 cm and 4 mm, respectively) were achieved in the seedlings which budded on 10 September. In contrast, shoot length was the shortest (3.93 cm) in seedlings that were budded on 20 August, and shoot diameter was almost similar (2.39, 2.23 and 2.72 mm) in all seedlings budded on 20 August, 1 September and 10 September, respectively. This study showed that 20 September was the best time for conducting budding of P. vera seedlings which were produced in nursery black bags in the current season.

Smartphones and wearable devices offer promising perspectives for processing and collecting velocity, variety, and high-quality data in healthcare scenarios. Collecting, investigating, analyze, and mining health data to generate individual and public health rules. These rules will measure and enhance the quality of everyday life. However current health systems are limited on their local data collection. As the current big data is so underutilized is because many challenges are existing. The aim of this study was to point the challenges of smartphone big data technologies and big data.

Purpose Novel particle engineering approach was used in this study to generate high dose inhalable effervescent particles with synergistic effects against Pseudomonas aeruginosa biofilms. Methods Spray dried co-amorphous salt of ciprofloxacin (CFX) and tartaric acid (TA) was prepared and coated with external layer of sodium bicarbonate and silica coated silver nanobeads. Design of experiments (DOE) was used to optimize physicochemical properties of particles for enhanced lung deposition. Results Generated particles were co-amorphous CFX/TA showing that CFX lost its zwitterionic form and exhibiting distinct properties to CFX/HCl as assessed by FTIR and thermal analysis. Particles exhibited mass mean aerodynamic diameter (MMAD) of 3.3 μm, emitted dose of 78% and fine particle dose of 85%. Particles were further evaluated via antimicrobial assessment of minimum inhibitory concentrations (MIC) and minimum biofilm eradication concentration (MBEC). MIC and MBEC results showed that the hybrid particles were around 3–5 times more effective when compared to CFX signifying that synergistic effect was achieved. Diffusing wave spectroscopy results showed that the silver containing particles had a disruptive effect on rheological properties as opposed to silver free particles. Conclusions Overall, these results showed the potential to use particle engineering to generate particles that are highly disruptive of bacterial biofilms.

Article InformationCommon bean anthracnose is a major production constraint in bean growing regions of Ethiopia. This study aimed to determine whether foliar sprays of mancozeb, folpan and mancolaxyl or antagonistic bioagents; Trichoderma harzianum, Trichoderma viride and Pseudomonas fluorescens could reduce anthracnose symptoms and consequently, increase yield and yield components. A total of seven treatments were arranged in a randomized complete block design with three replications. Statistical analysis showed significant differences among treatments. Anthracnose incidence, severity, infected pods per plant and the area under disease progress curve were highest in the control plots compared to the fungicide sprayed and bioagent treated seed plots. The highest percentage of infected pods per plant, 78.9 and 55 were recorded on the control and mancozeb sprayed plots respectively. The highest AUDPC value resulted in the lowest yield of 1.01 t/ha in the control plots compared to a highest yield of 3.33 t/ha from the sprayed plots with folpan and 1.79 t/ha from plots treated with Pseudomonas fluorescens. Relative yield losses of 69.67, 46.25 and 22.82% were recorded from the control, seed treated plots with P. fluorescens and sprayed plots with mancolaxyl respectively. Economic analysis revealed that the highest rate of return of 8,740 was obtained from Pseudomonas fluorescens seed treatment and the highest net benefit; 43,154 on folpan foliar spray treatment. The results of the present study support the novel possibility of using folpan foliar spray and Pseudomonas fluorescens seed treatments to decrease anthracnose symptoms in bean plants and consequently, achieve greater yield.
