Symmetry and Metal Additive Manufacturing
Additive manufacturing (AM) is proving to be a promising new and economical technique for the manufacture of metal parts. This technique basically consists of depositing material in a more or less precise way until a solid is built. This stage of material deposition allows the acquisition of a part with a quasi-final geometry (considered a Near Net Shape process) with a very high raw material utilization rate.

Cyber-Ethnography
Cyber-ethnography, also known as virtual ethnography, digital ethnography and most commonly online ethnography, is an online research method that adapts ethnographic methods to the study of the communities and cultures created through computer-mediated social interaction. As modifications of the term ethnography, cyber-ethnography, online ethnography and virtual ethnography (as well as many other methodological neologisms) designate particular variations regarding the conduct of online fieldwork that adapts ethnographic methodology. There is no canonical approach to cyber-ethnography that prescribes how ethnography is adapted to the online setting. Instead individual researchers are left to specify their own adaptations. Netnography is another form of online ethnography or cyber-ethnography with more specific sets of guidelines and rules, and a common multidisciplinary base of literature and scholars. This article is not about a particular neologism, but the general application of ethnographic methods to online fieldwork as practiced by anthropologists, sociologists, and other scholars.

FP-C
The Flight Paramedic Certification (FP-C) is an advanced certification that indicates an individual has attained the designation of Certified Flight Paramedic. The FP-C certification exam is administered by the International Board of Specialty Certification (IBSC) and the Board for Critical Care Transport Paramedic Certification (BCCTPC), a not-for-profit organizations responsible for the administration and development of specialty certification exams for critical care professionals. The test is administered by PSI and Applied Measurement Professionals (AMP) to assure compliance with the highest testing standards. This certification is designed to be successfully approved only for experienced paramedics who have demonstrated advanced knowledge of critical care medicine by passing an exam consisting of 125 scored items and 10 unscored items within a 2.5 hour window. As of February 22, 2018 there are 6458 certified flight paramedics worldwide, 494 of whom hold dual certification as a CCP-C. The FP-C, or CCP-C, and/or Critical Care Emergency Medical Transport Program (CCEMTP) certifications are often a requirement to work as a flight paramedic in the United States. The FP-C does not have an associated course, unlike the CCEMTP, although review courses and study guides available. The FP-C is considered comparable in difficultly to the Critical Care Paramedic Certification (CCP-C). Experience in the air medical or critical care transport fields is recommended before attempting to take the exam. However, there is no minimum education component required, and the examination does not require minimum years of experience, therefore new paramedics who have just completed school are eligible to take the exam and receive certification. In addition, there is no practical skills test associated with the examination, unlike the NREMT paramedic exam. Many agencies may require prospective employees to demonstrate practical competency in other courses (TPATC, ATLS-audit, CCEMTP, etc.) prior to being considered for employment. A candidate must hold a current paramedic license and have active certifications in Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS), Pediatric Advanced Life Support (PALS), Prehospital Trauma Life Support (PHTLS), and other advanced certifications.

Characteristics of Acid Sulphate Soils of Ganges Delta
Soil is a finite natural resource and is indispensable for human civilization because it is the medium for food production for the biosphere. Continued soil degradation is a forerunner of catastrophe for the living world. The protection of healthy soils and the restoration of problem soils are strongly needed in the current agricultural scenario as competition for urbanization and other human needs for land resources limits the scope for the further availability of land for agriculture. Naturally occurring degraded soils, such as acid sulphate soils, can be restored with scientific interventions and advanced management strategies. The Ganges Delta is a densely populated region, where the inhabitants’ major livelihood is agriculture. Soil acidity and salinity restrict crop performance in this coastal region, particularly the acid sulphate soils (ASSs) posing a risk to agriculture. ASSs are developed from land-use changes from mangrove forest to agricultural land in this region.

Hydrogels Combined with Silver Nanoparticles against Antimicrobial Resistance
The development of multidrug-resistant (MDR) microorganisms has increased dramatically as a natural consequence of the misuse and overuse of antimicrobials. The World Health Organization (WHO) recognizes that this is one of the top ten global public health threats facing humanity today, demanding urgent multisectoral action. In this sense, metallic nanoparticles (such as silver nanoparticles) have emerged as promising alternatives due to their outstanding antibacterial and antibiofilm properties. The efficient delivery of the nanoparticles (NPs) is also a matter of concern, and studies have demonstrated that hydrogels present an excellent ability to perform this task.

Type II Topoisomerases
Type II topoisomerases are essential enzymes that modulate the topological state of DNA supercoiling in all living organisms. These enzymes alter DNA topology by performing double-stranded passage reactions on over- or underwound DNA substrates. This strand passage reaction generates a transient covalent enzyme–cleaved DNA structure known as the cleavage complex.

Polyethylene Terephthalate Recycling Techniques
Polyethylene terephthalate (PET) is a widely used thermoplastic with excellent properties, making it a popular choice for various packaging and single-use plastic products. Its exceptional tensile strength, processability, transparency, thermal stability, barrier properties, toughness-to-weight ratio, and chemical resistance have contributed to its widespread use. However, the significant consumption of PET has led to a substantial amount of PET waste, especially in the form of single-use packaging. This has raised concerns about the environmental impact of plastic waste, such as marine pollution and landfill accumulation.

Electrode Materials for Supercapacitors in Hybrid Electric Vehicles
For hybrid electric vehicles, supercapacitors are an attractive technology which, when used in conjunction with the batteries as a hybrid system, could solve the shortcomings of the battery. Supercapacitors would allow hybrid electric vehicles to achieve high efficiency and better power control. Supercapacitors possess very good power density. Besides this, their charge-discharge cycling stability and comparatively reasonable cost make them an incredible energy-storing device. The manufacturing strategy and the major parts like electrodes, current collector, binder, separator, and electrolyte define the performance of a supercapacitor. Among these, electrode materials play an important role when it comes to the performance of supercapacitors. They resolve the charge storage in the device and thus decide the capacitance.
