This paper describes a robust autonomous disinfection tunnel to disinfect external surfaces of COVID-19 virus such as clothes and open body sections in public places such as airports, office complexes, schools, and malls. To make the tunnel effective and highly efficient, it has been provided with two chambers with three disinfection processes. Due to the multiple processes, the possibility of neutralizing the virus is quite high and higher than other solutions available at this point for this purpose. Chamber 1 sprays the solution of a disinfectant on the person. This solution can be either a dilute solution of approved chemical or any Ayurvedic/herbal disinfectant. Once the person enters chamber 2, he/she is exposed to hot air at 70 °C along with far-ultraviolet C rays (207-222 nm). Both chambers function autonomously by detecting a person in a chamber using ultrasonic sensors. The proposed tunnel is developed under industry-academia collaboration jointly by Technopark@iitk and ALIMCO under the ambit of the Ministry of Human Resources Development and the Ministry of Social Justice and Empowerment, respectively. The tunnel is referred to as the 'Techno Advanced Disinfection Tunnel' (TADT).

Scalp avulsion injuries are usually attributed to entrapment of long hair or clothing in agricultural or industrial machinery or traffic accidents. Though rare, these injuries may be dangerous, and resulting cosmetic defect and alopecia lead to social stigma and poor self-esteem. Early intervention in the form of microvascular repair and replantation prevent morbidity and improve outcome. In this case series, we have discussed 3 cases of scalp replantation, 2 complete and 1 partial. Immediate microvascular reconstruction was planned in each case. Single surgical team approach was followed, vessels were identified and operated under an operative microscope. No vein grafts were used. Operative outcome was good, and scalp healed well. Cosmetic outcome was excellent, and there was no need for secondary revisions or use of tissue expanders. Immediate referral of such cases to institutes with facility for microvascular repair is recommended to reduce ischemia time. Superficial temporal artery is the first choice for microvascular repair in scalp replants, and a single artery anastomosis is sufficient to perfuse the entire scalp. Deep temporal artery is a viable alternative in cases where repair with superficial temporal vessels will require use of vein graft, cutting short operative time and associated complications.
