Early blight is one of the major diseases of tomatoes that affects the leaves and fruit quality. Detection and estimation of the disease severity are performed using the visual observation method. Visual detection requires significant time for visual inspection of a large cultivated area. Thus, image processing techniques have proven to be an effective method as compared to visual analysis. In this study, digital image processing methods and techniques were used to detect early blight of tomato, estimate the disease severity, and classify tomato leaves. Totally, 198 infected plants were randomly taken from the Haramaya University research site "Raree" at four different times. Diseased potato leaf images were captured, resized, and stored for experimentation. The stored images were processed using median filtering to remove noise while preserving useful features in an image and image enhancement. The RGB images were transformed to gray scale and CIELAB color space, and the k-means clustering was applied to estimate the disease severity of the potato leaves, and Otsu’s thresholding algorithm was applied to estimate the disease severity of both the detached and live leaves. MATLAB algorithms will be developed to determine the total area and infected lesion area of the leaf samples.

Many students suffer from the sound of air conditioners and others suffer from light intensity in classroom. The air conditioners and light intensity affect the efficiency and quality of education. Urduino is used a lot in industrial areas because there is a lot of noise pollution. Additionally, it can be used in high traffic regions as well as to monitor noise in different parts of the city. It can also be used in education systems to monitor the noise in classrooms. The purpose of this study was to monitor the noise in classrooms by Arduino Nano that interfaced with a Sound Sensor. A study was conducted to determine the ambient sound and light intensity of a convenience sample at school during September, October and November 2021. Six classrooms’ samples corresponding to hourly fractions of the average sample broken down into the following periods: from 10:00 am to 2:50 pm. Sound levels were measured to assess acoustic conditions. Light levels were measured to assess light conditions. Each classroom from 1 to 6 was tested the ambient sound intensity and light using an Arduino. Noise varies with time and place. The sound level varies between 27.5 dB and 65 dB with the average sound level in the classrooms was 43.53 dB greater than recommended sound level limit of 35 dB. The light intensity varies between 62.50 lux and 208.5 lux. The average light levels around the recommended 300 lux. Everyone emphasized the quality of using the device to measure the noise level in the classroom. The use of the device leads to monitor the noise of the air conditioner or replacing it. The device has the potential to significantly change the noise pollution monitoring system at school. Researchers recommend all students and authorities the importance of the Arduino.

Artificial light at night has been reported to have significant effects on the physiology and behaviour of animals by its impact on their circadian rhythm. This study investigated the effect of artificial light spectra at night on neurotransmitter activities and neurobehavioural changes in the albino rat. Blue (470 nm) and red (665 nm) lights were used; with ambient light and darkness serving as positive and negative controls, respectively. The rats were exposed to daylight from 6 am to 6 pm and 12 hours of artificial light (6 pm - 6 am) daily (light sources were 13 Watt compact florescent electric bulbs). Neurobehavioural outcomes were measured using the Open Field Test (OFT) and Morris Water Maze (MWM).

I present some key considerations of the biofilm disease as part of two complex pathologies such as bone and joint infections and prosthetic joint infections, taking into account the bacterial pathogenic factors to understand the particular nature of these infections, and to achieve an accurate diagnosis and management beyond the antimicrobial therapy. I mention some personal experience of many years in the medical microbiology laboratory and next to the patient’s bed.

AuthorSurface texturing is an indispensable process for solar cell fabrication. The interaction of the surface with the incoming sunlight is controlled by texturing in such a way that the absorption is maximized through multiple interactions. Wet and dry etching techniques have been used to create textured surfaces on solar cells. Other than standard alkaline texturing used by the industry, metal assisted etching (MAE) appears to be a promising texturing technique with greater potential application for multi-crystalline solar cell fabrication. It is possible to achieve both random and periodic patterns with MAE which is relatively cheaper than dry plasma etching techniques. In this study, periodic hole patterns with micron sized diameters and periodicity were aimed to be achieved.

The purpose of this study is to synthesize and characterize nanodroplets, loaded with docetaxel for treatment of prostate cancer under MR-guided focused ultrasound. Water insoluble docetaxel encapsulated in nanodroplets is expected to be delivered into tumors with greater efficiency while minimizing drug related systemic toxicities when used in combination with focused ultrasound. The sequence of our studies toward development and characterization of docetaxel-loaded nanodroplets is as follows. First, we developed methods for synthesis of ultrasound-responsive, docetaxel-loaded nanodroplets (Doc-nd) by a solid dispersion technique. Secondly, we characterized Doc-nd by its morphology and size distributions using a dynamic light scattering (DLS) method.

Capsaicin, an active ingredient of Capsicum fruit, is currently undergoing “revival” in the clinical management of pain. However, the choice of its formulation is rather limited to the use of “old-fashioned” tinctures and recently the patches. In an attempt to improve the therapeutic outcome and develop its skin-friendly formulation, we prepared the vesicle-based drug delivery system with capsaicin.
