A critical review on biochar for the removal of toxic pollutants from water environment.

As an effort to tackle some of the most pressing ecological issues we are currently experiencing, there has been an increasing interest in employing biomass-derived char products in various disciplines. Thermal combustion of biomass results in biochar production, which is a remarkably rich source of carbon. Not only does the biochar obtained by the thermochemical breakdown of biomass lower the quantity of carbon released into the environment, but it also serves as an eco-friendly substitute for activated carbon (AC) and further carbon-containing products.

A review on recent advancements in the treatment of polyaromatic hydrocarbons (PAHs) using sulfate radicals based advanced oxidation process.

Polyaromatic hydrocarbons (PAHs) are the most persistent compounds that get contaminated in the soil and water. Nearly 16 PAHs was considered to be a very toxic according US protection Agency. Though its concentration level is low in the environments but the effects due to it, is enormous.

Biodegradation of textile dye Rhodamine-B by Brevundimonas diminuta and screening of their breakdown metabolites.

The carcinogenic Rhodamine-B dye is recalcitrant which could cause serious hazards to human beings. Degradation with the application of unique bacterial strain is a sustainable technique. The bioremediation technique showed great potential to degrade a variety of recalcitrant pollutants like dyes.

Stimulation of Bacillus sp. by lipopeptide biosurfactant for the degradation of aromatic amine 4-Chloroaniline.

This study aims to reveal that the biosurfactant act as a stimulant in aromatic amine 4-Chloroaniline (4-CA) degradation. Isolated degrading strain Bacillus sp. was used for the production of biosurfactant with help of substrate such as engine oil.

Implementation of the pulse rhythmic rate for the efficient diagnosing of the heartbeat.

The mortality rate has risen due to the increase in number of cardiac patients in recent times due to the lack of unawareness of the symptoms. This work mainly aims to detect the anomalies of the rhythmic conditions of the pulse derived from the electrocardiogram (ECG) pattern based on correlation and the method of mapping. As this device is a programmable one and a real-time application wearable system on the wrist which is physically connected to the veins, it continuously monitors the photoplethysmography (PPG) pattern based on certain parameters and rhythmic conditions, it ensures whether the patient is under the safe condition or not.

Transcervical approach to the removal of a deep-seated giant submandibular calculus and the submandibular gland.

Sialolithiasis is among the most common disease affecting the major salivary glands whereby the submandibular gland or its duct is affected in the majority of cases. We report a case of the surgical removal of a giant sialolith along with the submandibular gland using the transcervical approach and its clinical outcome.

Toxicity Evaluation of Pũrṇa Cantirotaya Centũram, a Siddha Medicine in Wistar Rats.

Pũrṇa Cantirotaya Centũram (PCC), a herbometallic formulation of Siddha medicine, consists of mercury, sulphur, and gold, processed with red cotton flower and plantain stem pith juices. To evaluate its safety, acute and 28-day repeated oral toxicity studies were performed following OECD test guidelines 423 and 407, respectively. In acute study, PCC was administered orally at 5, 50, 300, and 2000 mg/kg body weight.
