Useless or used less? Poroscopy: The evidence of sweat pores.

Poroscopy is the study of sweat pores present on the papillary ridges of the skin. This review paper aims to examine existing literature on poroscopy so that its relevance as a tool in personal identification can be established. Moreover, this paper aims to expound the various aspects of sweat pores as well as, highlight the contribution of poroscopy in latent, partial, and automated fingerprint matching. The relationship between sexual dimorphism, age, and sweat pores, effect of development technique and nature of surface on pore details, and use of sweat pores for liveness detection in biometric systems has also been explored. A review of all potentially relevant articles was conducted wherein, the non-relevant papers were excluded by screening their titles and abstracts following which, full-text review of all articles that met the inclusion criteria was carried out. The authors concluded that sweat pores present additional distinctive information for facilitating personal identification when used along with level 2 details. Furthermore, out of the various pore parameters namely, number, shape, size, inter-distance, position, and type, pore inter-distance was found to be most reliable.

Reproducibility and reliability of fingerprint microfeatures: Effect of immersing hand in water at different temperatures.

Poroscopy is the specialized study of sweat pores found on the papillary ridges of the skin. However, the science of poroscopy is not being used to its full potential. The present study was conducted with the goal to assess the effect of immersing hand in water at various temperatures i.e., room temperature (20-30 °C), hot temperature (40-50 °C), and cold temperature (0-10 °C), for 1, 5 and 10 min, on the reproducibility of pore microfeatures namely, area, inter-distance, and angle, in an attempt to demonstrate their reliability in fingerprint matching. As far as the authors are aware, no prior research has attempted to evaluate the impact of immersing hand in water, at different temperatures, on the reproducibility of third level details. Statistical analysis of data revealed that pore inter-distance and angle were reproducible in nature thereby, highlighting their significance in fingerprint matching.

Nutrition, physical activity and psychological status during lockdown due to Covid-19

Aim of the present study was to assess physical activity, nutrition and psychological status of the population during lockdown due to covid-19. Online survey was conductedamong 534 participants within the age range of 16-78 years using convenient sampling. Participantsfrom varied regions within India and abroad were enrolled for the present study. Volunteered participants were solicited to take part in a survey that has to be carried out by filling an online questionnaire form available to them as a URL link in the invitation through WhatsApp/Messenger. The gathered data has been compiled, coded and cleaned using Microsoft Excel. Analysis has been carried out employing descriptive and inferential statistics in SPSS 17.0.Majority of participants in the studied population showed significant change in their nutrition and physical activity status due to lockdown. Covid-19 lockdown did limit their daily activities. It also had impacted their psychological status.The current investigation accentuates the need to pursue suitable life style for the maintenance of optimum metabolism and physiology. Sticking to more regular timetable of meals, effective management of stress levels and continued physical activity during the quarantine and in all the following phases of living is desirable.
