Digital Twin Technology in Internet of Things (IOT)

Developments in virtual technology and data acquisition technology put way to digital twin (DT) technology. Digital twin is a virtual entity that is linked to a real-world entity. Both the link and the virtual representation can be realized in several different ways. Digital Technology plays a very much key role in different areas like in production management, manufacturing, health care, smart cities and so on. Mainly Digital Twin Technology is developed to improve manufacturing processes. With the development of new-generation information and digitalization technologies, more data can be collected, and it is time to find a way for the deep application of all these data. As a result, the concept of digital twin has aroused much concern and is developing rapidly. Digital twins facilitate to monitor, understand, and optimize the functions of all physical entities and for humans and also provide continuous feedback to improve quality of life and well-being.  Digital Twin is best described as the effortless integration of data between a physical and virtual machine in either direction. This paper provides an overview of the Digital Twin technology used in different work spaces and also how it will be effective in the Internet of Things network

Changes in genetic diversity parameters in unimproved and improved populations of teak (Tectona grandis L.f.) in Karnataka state, India

Teak (Tectona grandis L. f.; family Verbanaceae) is an important plantation tree species in the tropics and in India one of the first species to be prioritized for improvement. Improvement efforts for the last 50 years have essentially concentrated on augmenting quality seed production by establishing seed production areas (SPA) and clonal seed orchards (CSO). Presently, these two form the main sources of quality planting material for teak throughout the country. However, there is no information on the genetic quality of such sources nor information on the progeny used in plantation programmes. Reports of studies based on coniferous and tropical species provide conflicting results on the impact of domestication on the genetic diversity of populations (Chaisurisri and El Kassaby 1994; Rajora 1999; Moran et al. 2000; Godt et al. 2001; Icgen et al. 2006). Also the impact of domestication on the genetic diversity of progeny populations is poorly understood (Stoehr and El-Kassaby 1997; Schmitdtling and Hiplins 1998). Such studies become pertinent not only for gauging the impact of selection on reforestation stock, but also for effective genetic conservation of existing breeding populations. We therefore address two issues in the present study: (i) the change in genetic diversity with increasing levels of improvement, and (ii) the impact of the above change on genetic diversity of progeny populations

Influence of levels of genetic diversity on fruit quality in teak (Tectona grandis L.f.)

The study on the influence of genetic diversity on the fruit emptiness and seed germination (as a measure of fruit quality) of teak populations was carried out. The populations comprised three unimproved plantations, three seed-production areas and a clonal seed orchard within Karnataka. Significant variation between the populations was observed for fruit emptiness, seed germination and Jaccard’s dissimilarity index of the parent population. Genetic dissimilarity of populations was positively correlated to fruit emptiness and negatively correlated to seed germination. It is inferred that higher genetic dissimilarity of individuals within the population results in higher flower asynchrony and close-related mating, thereby leading to higher inbreeding depression manifested in the form of higher emptiness and low germination percentage

Antenatal laparoscopic management of ovarian cyst: a case report

The frequency of adnexal mass in pregnancy ranges from 2% to 10%, dermoid cyst is the most common ovarian germ cell tumor during pregnancy which could be asymptomatic or symptomatic, management through laparoscopy must be considered as it provides several advantages, including reduced postoperative pain, analgesic use, hospitalization time and better cosmetic result. Here we are reporting a case of an unbooked 35 years old primigravida at 16 weeks and 4 days gestation with history of retention of urine. Ultrasound showed a live foetus of 16 weeks gestation with bilateral mild maternal hydroureteronephrosis and complex cystic mass of 13×10 cm in right lumbar region suggestive of ovarian mass. Patient was clinically stable, hence exploratory laparoscopy was taken up the next day. Intraoperatively, dermoid cyst was found in the right ovary. Right ovarian cystectomy was performed. She had an uneventful postoperative period and discharged. She was monitored for the rest of the pregnancy and it was uneventful. She had spontaneous full term normal vaginal delivery of female baby weighing 2.8 kg. Although the patient was clinically stable, large ovarian cyst are predisposed for future complications, hence antenatal diagnosis and appropriate intervention is crucial for good outcome
