EMPLOYABILITY OF ADVANCED IMAGE PROCESSING TO EFFECTIVELY COUNT AND CLASSIFY THE BACTERIAL COLONIES

Specification of Bacterial Colonies is needed in many fields, such as clinical analysis, biomedical examination for anticipation of severe illnesses, and the drug industry to avoid tainting items. Existing Bacterial Colony counter frameworks count Bacterial Colony physically, which is a tedious, less effective and dreary cycle. Henceforth, mechanization for calculating bacterial settlement was required. The proposed strategy counts these settlements naturally utilizing picture handling strategies. This strategy will give a more superior level of precision in the counting of bacterial provinces. The proposed method takes a picture of bacterial settlement and converts it into grayscale. Otsu thresholding is applied for the division of the image, further its change into a double shot. From that point onward, morphological activities are used to tidy up the picture by eliminating commotion and superfluous pixels. Distance and watershed changes are applied to double vision to make parts among covered and joint microscopic organisms. Locale properties and marking data of fragmented picture is utilized for counting of the bacterial province.

Colloidal Oxide Perovskite Nanocrystals: From Synthesis to Application

Nanocrystals (NCs) are complex systems that offer a superior level of detailed engineering at the atomic level. The large number of novel and revolutionary applications have made nanocrystals of special interest. In particular oxide perovskites are one of the most widely investigated family of materials in solid-state chemistry, especially for their ferroelectric and superconducting properties. In addition to these well-known properties, perovskites show good electrical conductivity (close to metals), ion conductivity and mixed ionic-electronic conductivity. In that sense, controlled synthesis of nanomaterials with special care over size and shape are essential in many fields of science and technology. Although it is well-known that physical methods deliver excellent quality nanomaterials, their high production cost has increased the interest to more affordable alternative chemical processes. In this review, we focus on the preparation of sub-10 nm oxide perovskite nanocrystals and the main strategies used to control the final properties of the obtained products. In the second part, we present the methods available for nanocrystal solutions processing together with the most remarkable applications foreseen.

The Process The Formation of The Collective Leadership on The Corruption Eradication Commission

This article was written based on the findings of research that examines the process of formation of collective leadership implemented by the Corruption Eradication Commission (Komisi Pemberantasan Korupsi: KPK) in Indonesia during its inception in 2003 until the end of the leadership of Abraham Samad 2015. The results of the study indicate that the KPK's collective leadership was gradually formed through several stages can be identified in 3 development cycles. The first stage is a pioneering cycle that requires prerequisites for the formation of collective leadership in order to operate the leadership mechanism in the KPK's organizational structure. Second, the critical cycle, namely the operational trials of collective leadership that have the opportunity to succeed or fail. This cycle is characterized by collaboration between structures in the collective decision making process. Third, the operational stabilization cycle, is a stage of development that leads to the cohesiveness of KPK members and results in superior level of performance.

Blood Wettability of Different Dental Implant Surfaces after Different Pre-Treatments: Ultrasonic Instrumentation, Platelet-Rich Fibrin Coating, and Acid Etching. An In Vitro Study

Background: The blood wettability of titanium implant surfaces favors primary osseointegration and tissue healing in peri-implantitis. The current study aims to evaluate this property on the main different kinds of surfaces, brand new and after treatments. Methods: grade IV titanium disks were used, five machined, five laser-treated, five sandblasted. The experiment was on four steps. Between each step, specimens were sterilized. At the end of each step, a 4 µL blood drop was put on the samples, and contact angles were calculated. The steps consisted of—1: no treatment; 2: surface instrumentation with an ultrasonic titanium tip; 3: platelet-rich fibrin (PRF) coating and drying with sterile gauze; 4: etching with phosphoric acid, rinse and saline solution and air-drying. At the end of each phase, a blood drop was placed on the surfaces. Blood for PRF preparation and for calculation of contact angles was collected from a single source. Results: average wettability decreased after instrumentation, and increased after the PRF application to a superior level both to the first and second steps. The highest wettability was obtained after etching. This trend is statistically significant for machined and sandblasted surfaces. Conclusions: In the clinical environment, PRF and phosphoric acid used for conditioning exposed implant surfaces can be used for the healing of peri-implant tissues.

A four-electron Zn-I2 aqueous battery enabled by reversible I−/I2/I+ conversion

Electrochemically reversible redox couples that embrace more electron transfer at a higher potential are the eternal target for energy storage batteries. Here, we report a four-electron aqueous zinc-iodine battery by activating the highly reversible I2/I+ couple (1.83 V vs. Zn/Zn2+) in addition to the typical I−/I2 couple (1.29 V). This is achieved by intensive solvation of the aqueous electrolyte to yield ICl inter-halogens and to suspend its hydrolysis. Experimental characterization and modelling reveal that limited water activity and sufficient free chloride ions in the electrolyte are crucial for the four-electron process. The merits of the electrolyte also afford to stabilize Zn anode, leading to a reliable Zn-I2 aqueous battery of 6000 cycles. Owing to high operational voltage and capacity, energy density up to 750 Wh kg−1 based on iodine mass was achieved (15–20 wt% iodine in electrode). It pushes the Zn-I2 battery to a superior level among these available aqueous batteries.
