The purpose of this study is to explore the applications of 3D printing in space sectors. The authors have highlighted the potential research gap that can be explored in the current field of study. Three-dimensional (3D) printing is an additive manufacturing technique that uses metallic powder, ceramic or polymers to build simple/complex parts. The parts produced possess good strength, low weight and excellent mechanical properties and are cost-effective. Therefore, efforts have been made to make the adoption of 3D printing successful in space so that complex parts can be manufactured in space. This saves a considerable amount of both time and carrying cost. Thereof the challenges and opportunities that the space sector holds for additive manufacturing is worth reviewing to provide a better insight into further developments and prospects for this technology.

The potentiality of 3D printing for the manufacturing of various components under space conditions has been explained. Here, the authors have reviewed the details of manufactured parts used for zero-gravity missions, subjected to onboard international space station conditions and with those manufactured on earth. Followed by the major opportunities in 3D printing in space which include component repair, material characterization, process improvement and process development along with the new designs. The challenges like space conditions, availability of power in space, the infrastructure requirements and the quality control or testing of the items that are being built in space are explained along with their possible mitigation strategies.

These components are well comparable with those prepared on earth which enables a massive cost saving. Other than the onboard manufacturing process, numerous other components as well as a complete robot/satellite for outer space applications were manufactured by additive manufacturing. Moreover, these components can be recycled onboard to produce feedstock for the next materials. The parts produced in space are bought back and compared with those built on earth. There is a difference in their nature, i.e. the flight specimen showed a brittle nature, and the ground specimen showed a denser nature.

This review discusses the advancements of 3D printing in space and provides numerous examples of the applications of 3D printing in space and space applications. This paper is solely dedicated to 3D printing in space. It provides a breakthrough in the literature as a limited amount of literature is available on this topic. This paper aims at highlighting all the challenges that additive manufacturing faces in the space sector and also the future opportunities that await development.

The purpose of the study is to classify the radiographic images into three categories such as fillings, cavity and implant to identify dental diseases because dental disease is a very common dental health problem for all people. The detection of dental issues and the selection of the most suitable method of treatment are both determined by the results of a radiological examination. Dental x-rays provide important information about the insides of teeth and their surrounding cells, which helps dentists detect dental issues that are not immediately visible. The analysis of dental x-rays, which is typically done by dentists, is a time-consuming process that can become an error-prone technique due to the wide variations in the structure of teeth and the dentist's lack of expertise. The workload of a dental professional and the chance of misinterpretation can be decreased by the availability of such a system, which can interpret the result of an x-ray automatically.

This study uses deep learning (DL) models to identify dental diseases in order to tackle this issue. Four different DL models, such as ResNet-101, Xception, DenseNet-201 and EfficientNet-B0, were evaluated in order to determine which one would be the most useful for the detection of dental diseases (such as fillings, cavity and implant).

Loss and accuracy curves have been used to analyze the model. However, the EfficientNet-B0 model performed better compared to Xception, DenseNet-201 and ResNet-101. The accuracy, recall, F1-score and AUC values for this model were 98.91, 98.91, 98.74 and 99.98%, respectively. The accuracy rates for the Xception, ResNet-101 and DenseNet-201 are 96.74, 93.48 and 95.65%, respectively.

The present study can benefit dentists from using the DL model to more accurately diagnose dental problems.

This study is conducted to evaluate dental diseases using Convolutional neural network (CNN) techniques to assist dentists in selecting the most effective technique for a particular clinical condition.

In this paper, the authors study the behavior of heat and mass transfer between parallel plates of a steady nanofluid flow in the presence of a uniform magnetic field. In the model of nanofluids, the essential effect of thermophoresis and Brownian motion has been encompassed.

The variation of parameters method has been exploited to solve the differential equations of nanofluid model. The legitimacy of the variation of parameters method has been corroborated by a comparison of foregoing works by many authors on viscous fluid.

An analysis of the model is performed for different parameters, namely, viscosity parameter, Brownian parameter, thermophoretic parameter and magnetic parameter.

The variation of parameters method proves to be very effective in solving nonlinear system of ordinary differential equations which frequently arise in fluid mechanics.

The purpose of the study was to evaluate the impact of Introduction of Smart Teaching and Learning (INSTAL) project on students' academic achievements in terms of students' science scores. Information and communication technologies (ICT)-based initiative was introduced in Sindh Education Foundation (SEF) schools at District Khairpur, Sindh, Pakistan. The aim of the study was to identify whether science test scores of students have been improved with the use of INSTAL facility at schools or remained the same at SEF-supported schools.

The quantitative research approach has been used in the current study, and within it a quasi-experimental research design was employed. The descriptive (mean, standard deviation) and inferential statistics (independent sample t-test and paired sample t-test) were computed to find the pre- and post-difference in science scores of students. Both primary and secondary data were used. The primary data were gathered through questionnaire from 48 science teachers. Whereas, secondary data of 382 students who used ICT-based facility under INSATL project for two academic years were taken from quality assessment test (QAT) scores conducted by third party in SEF-assisted schools in District Khairpur.

The findings of the study revealed that the students' science scores improved by 10% in one year and 23% in two years with the use of ICT-based facilities under INSTAL project. Also, it can be concluded from the results that ICT has a positive as well as statistically significant impact on students' science learning by using INSTAL facility in schools. Results of the study show that students' level of interest toward learning science has been enhanced by the use of ICT.

As the world is rapidly moving toward digitalization, the modes of teaching and learning have been changing. ICT plays a very significant role in the betterment of education. ICT helps to achieve socio-economic development of a country. However, Pakistan, being a developing country, has not that much resources, and ICT-based learning is not common in Pakistan. Therefore, it is very important to be aware people about the usage of technology in teaching and learning. The present study is an attempt to create such type of awareness. Moreover, the current study may be the first kind of study in the context of Pakistan which used TPACK as theoretical framework, and this study may contribute to the body of knowledge in the context of ICT.

Implementing ICT-based software for teaching and learning in rural context of Pakistan was a challenging task, but it has brought positive results in terms of student's achievement. This may be the first study that has been conducted in the context of adopted schools of SEF.
