Published: November 2021

The aim of this paperis to determine the quality of TV classes World around us and Nature and Social Science,which were broadcasted on Radio Television of Serbia during the pandemic in the school year 2019/20. Although the work was indirect, so the immediate interaction between the teacher and student is missed. Therefore, teacher's questions were the way of establishing some kind of interaction in such classes organized in this manner. For this reason, we wanted to establish the types of questions that teachers were asking to students through small screens. Considering that the achievements of learning are based on Bloom's Taxonomy, we were analyzing sixteen TV classes and classified the questions the teachers asked according to cognitive area, on six educational levels. The results indicate that the most common were question within lower cognitive levels were (knowledge, understanding and application), and that there are no statistically significant differences in cognitive levels on questions asked between lower (1st and 2nd grade) and higher grades (3rd and 4th grade), on the other hand, on the classes of determination of educational content teachers were asking statistically significant quality questions compared to the classes of interpretation.

Published: November 2021

The coronavirus pandemic has caused a complete reorganization of the education system. Thus, the entire process of education began to take place online, using various platforms and digital tools. This implies a certain adaptation of the work of teachers and pupils. In the changed conditions, gifted pupils represent a particularly sensitive group of individuals, because working with them requires a lot of attention, a stimulating environment, and the learning process should follow their needs and interests in order to fully develop their potential. Questions are asked: does learning in a changed social context stimulate the development of potential in gifted pupils, and does it follow their needs and interests. The aim of this article is achieved on a theoretical level, by applying the method of theoretical analysis and content analysis techniques. The pedagogical implications of this article are reflected in the improvement of optimal conditions for the education of the gifted in a changed social context.
Značaj porodice za razvijanje govorne kulture dece predškolskog i učenika mlađeg školskog uzrasta u izmenjenim uslovima rada

Speech, as a social category, stems from the child's need to be in contact with others and communicate with them. In that way, child learns about active communication and interaction, expresses his thoughts, feelings, attitudes and needs. Nurturing the speech culture of the youngest is one of the main objectives of preschool institutions; before that, of families, and especially school. Great attention is paid to teaching children/students how to express themselves and communicate, starting from preschool age with the systematic effort by preschool teachers, and later, in school, teachers continue with this effort, along with, of course, the family as the first and unavoidable link in that chain. The quality of communication and interaction between the child/student and other participants largely determines the speech, but also the overall development of personality and the improvement of the culture of linguistic expression. The altered learning conditions in which the education process has been taking place for more than a year now have significantly impaired the quality of communication in preschool and school. At one time, the interaction, which was otherwise reduced, was non-existent at all; the duration of school lessons has been shortened, the wearing of masks has been introduced, as a result of which breathing is difficult, and thus speech fatigue occurs, which seriously threatens to jeopardize the still underdeveloped speaking abilities of children/students in the lower grades of primary school. This paper will discuss the importance of family for the development of speech culture of preschool and primary school children, the need and opportunities for enhanced cooperation with preschool/school in altered learning conditions in order to create more frequent scenarios for children/students to speak more at home through creative tasks including active reading, retelling, talking and describing in order to successfully develop the speaking skills of children/students outside the preschool/school.

Authors:   University of Kragujevac, Faculty of Education, Uzice, Stamatović Jelena , Stakić Mirjana
Published: November 2021

The paper is based on the overview and description of ten monographs from in- ternational scientific conferences held in the period between 2011 and 2021 at the Facul- ty of Education in Uţice, and is aimed at recording topics and issues discussed in them, and making suggestions for future research of problems, goals and perspectives in the teaching and learning process. The review of the monographs from these international scientific conferences showed that the interest of theoreticians and practitioners is firmly focused on general questions of education and rearing, teaching and learning, as well as questions of educational assessment and evaluation, textbook quality, and education and professional development of teachers. Topics in the field of elementary education are predominant, so in the future, it would be worth paying more attention to the current topics in the field of preschool and higher education.
Perspectivism and Special Relativity
Authors: Khalili Mahdi
Published: November 2021

The special theory of relativity holds significant interest for scientific perspectivists. In this paper, I distinguish between two related meanings of “perspectival,” and argue that reference frames are perspectives, provided that perspectival means “being conditional” rather than “being partial.” Frame-dependent properties such as length, time duration, and simultaneity, are not partially measured in a reference frame, but their measurements are conditional on the choice of frame. I also discuss whether the constancy of the speed of light depends on perspectival factors such as the idealized definition of the speed of light in a perfect vacuum and the Einstein synchronization convention. Furthermore, I argue for the view that the constancy of its speed is a robust property of light according to the conditions of currently acceptable experimental setups pertaining to special relativity, and conclude that this view supports perspectivism.

Published: November 2021

The study sought to identify factors affecting revenue growth among County Governments in Kenya using Kiambu County as the case study. County Government of Kiambu consistently failed to meet its revenue collection targets following the creation of devolved governments after the promulgation of the new Constitution of Kenya 2010. County Governments were expected to collect own-source revenues to supplement equitable, conditional and unconditional grants received from the National Government. Its specific objectives included to establish the effect of public participation on revenue growth, to establish the effect of technology on revenue growth, to establish the effect of enforcement of laws on revenue growth, and to establish the effect of increase of taxation on revenue growth. The research employed a descriptive survey research design. Primary data was collected using questionnaires, while secondary data was derived from published material regarding devolution and revenue collection by sub-national governments in Kenya and beyond. The Statistical Package for Social Sciences and Microsoft Excel were used to analyse and process the primary data collected, and the information generated was presented in form of tables. All the factors affecting revenue growth (public participation, technology, enforcement of laws, and increase of taxation) were found to be significant using a multiple linear regression as shown by their positive beta coefficients of (ß=0.935) with P Value < 0.05 at .000, (ß=0.867) with P Value < 0.05 at .000, (ß=0.825) with P Value < 0.05 at .000, and (ß=0.725) with P Value < 0.05 at .000 respectively. These findings affirmed the importance of the factors under study and therefore County Governments should put due consideration for optimum revenue growth.

Authors:   Adekunle Ajasin University Akungba Akoko Ondo State Nigeria, Folorunso Ph.D Fasunwon, Adebayo
Published: November 2021

In almost every place in the world, the outbreak of the coronavirus pandemic is pushing societies, cultures and civilizations into uncharted territories. Social systems, economic structures and to an extent, political realities are being disrupted on a scale unprecedented in human recorded history. Educational systems are no exception, with more than 1.6 billion learners forced out of traditional schooling since the beginning of the pandemic. E-learning platforms and models are thus taking the center stage, leaping out from the shadows of traditional classroom-based learning with such force that many have argued it is indeed the future of learning. This paper examines the realities of such a paradigm shift within the Nigerian context, with particular spotlight on its advantages to the educational sector, as well as challenges that may hinder the realization of these advantages and nullify potential positive impacts.

The web has turned into a principal part of our conventional social and financial activities. The web isn't significant for singular clients just yet additionally for associations, since associations that offer web-based exchanging can accomplish an upper hand by serving overall customers. Webworks arriving at clients all around the globe with no commercial center limitations and with successful utilization of internet business. Consequently, Internet customers may be defenceless against different kinds of web risks, that may cause financial damages, information forgery, brand reputation mischief, the sacrifice of private information, and loss of customers' confidence in online business and electronic banking. Thusly, the reasonableness of the Internet for business exchanges becomes dubious. Phishing is seen as a design of web peril which is classified as the forte of mimicking a website of a legitimate undertaking proposing to gain a client's private accreditations, for instance, usernames, passwords, and federal retirement aide numbers. In this paper, we present an overview of cutting-edge research on such attacks. Besides, we expect to perceive the cutting-edge advancements in phishing, furthermore, give a far-reaching overview and comparison of these kinds of literatures to understand the hole that is as yet prevailing around anti-phishing. This overview will be for the most types of online phishing detection techniques for the last 4 years.

This paper aims to analyze the use of virtual reality (VR) in the wake of the COVID-19 pandemic to increase destination sustainability and to explore the authenticity of VR experiences as a substitute for real-life experiences. It begins by giving a brief background of the effect of the COVID 19 crisis on the tourism industry. Then archival research or document review is used to collect the data, it may, therefore, be analyzed through a thematic and content analysis. This paper showed VR is considered as a viable instrument to promote the sustainability of tourist destinations not only from an environmental and cultural perspective but also the economic aspect of host communities through the development of alternate forms of income. Promoting the use of VR may mitigate the possibility of virus spreading, increase destination sustainability and provide another option for a wider audience of visitors to see how prospective and worthy the sites are.
Western Feminism and Rescuing Non-Western Women
Authors: Waheed Manha , Cabezas César
Published: November 2021

Western feminism has become one of the most widespread feminist ideologies in our world today and it continues to gain popularity among those in the West who attempt to aid women in foreign nations. This particular feminism is rooted in “saving” non-Western women by attempting to mould their lives so that they may feel “empowered,” much like women in the West. What Western feminism fails to account for, however, is the lack of knowledge towards cultural contexts and the harm caused by Western feminists as they attempt to save these women who they deem oppressed due to their culture. The purpose of this paper is to analyze Western feminism from a variety of perspectives and find the flaws that prevent it from actually having a positive impact on women in the Global South. This essay includes references to prominent philosophic literature as well as present and historical examples of Western feminism that prove that the White Ignorance prevents these types of feminists from actually “rescuing” oppressed women. Through analyzing Western feminism from different lenses of White Ignorance, this paper provides an answer for how feminism can have a genuinely positive impact on non-Western women through the abolition of Structural White ignorance found in Western institutions and corporations.
A Welfare Analysis on GM Crop Market Structures and Existing Regulations
Authors: Lee Linda , Giesbrecht Aaron
Published: November 2021

Since their introduction in 1994, genetically modified (GM) crops have become a major sector of the agricultural industry in developing and developed countries. Despite this, many economic concerns have arisen regarding how governments regulate GM crops. These concerns have caused countries to ban GM crop usage, which has proven to be detrimental for national and international economies. This paper outlines the economic advantages of GM crop production and usage and surveys the current inefficiencies in the regulation of GM crops through a review on existing literature. It notes the increased farming efficiency, cost effectiveness, and rise in income for developing countries resulting from GM crop production and usage. It then considers why many of the listed potential benefits are unrealized, particularly due to the excessive market power given to GM seed producers, high barriers of entry into the GM market due to biosafety procedures, utility patents, and international trade asymmetries. Finally, the discussion section of the paper poses potential solutions by describing methods to efficiently regulate GM crops and suggesting possible areas of further research. The objective of this paper is to inform readers with minimal economic understanding of the potential economic benefits of GM crops and aid them in recognizing the optimal ways to regulate them.

Authors: Kim Colin , Oh Brian
Published: November 2021

The objective of this study was to provide insight into the anti-mask phenomenon that has been occurring throughout the world. Widely broadcasted through different forms of media, these anti-mask movements are a growing concern to the scientific community, as such exposure will only deter the progress towards ending the pandemic. In order to understand the psychological motivations behind the anti-mask sentiment, the present studies 29 videos, over 120 minutes of content covering anti-mask protests in Canada, Europe, and the United States. I also used East Asia as a control variable, as I reviewed 5 videos, around 35 minutes of footage to understand the psychology that makes East Asia more receptive towards mask use. By implementing a qualitative research design, I looked for key language themes (interviews, chants, signs) in order to apply thematic analysis to connect their negative sentiments that are associated with confirmation bias and motivated reasoning. Findings regarding confirmation bias and motivated reasoning have been linked to concerns regarding personal rights and distrust with the government, media, and science communities. In particular, the United States has an issue regarding national pride in connection to individuals’ personal rights. The goal is to give insight into ways the United States can improve mask adherence for future potential pandemics.

Authors: Zinchuk Nikolay , Bardukhinov Leonid
Published: November 2021

Based on the completed research and data summary on diamonds specific features (an example from the Siberian platform), conclusions were made that indications exist at all levels of their location: from kimberlite-related provinces, subprovinces, fields, diatremes to ore shoots. Population of diamond varieties in kimberlite rocks forms parasteric, rather than paragenetic, associations related to their coexistence in kimberlites. Morphological criteria of kimberlite diamond potential were defined depending on rounded diamonds content in them. Significant differences in kimberlites diamond potential were not revealed to the explored depth of diatremes. A conclusion about the absence of horizontal concentric zonality in the change of diamond typomorphic features was made.

Authors: Pomazansky Bogdan , Monkhorov Richard , Antonova Tat’yana , Malkovets Vladimir , Kulagin Alexey , Shalkina Marina , Batyr Viktoria , Sobakin Alexey
Published: November 2021

The porphyry kimberlite block (intrusive coherent kimberlite, after Scott-Smith, 2013) on the deep horizons of the Internationalnaya pipe is characterized by the lack of olivine macrocryst serpentinization, and the minimum degree of postmagmatic alteration in the matrix minerals. Garnet keliphitization and the composition of olivine and phlogopite outer zones are due to the interaction of deep minerals and the surrounding kimberlite melt at depth. The rapid melt crystallization contributed to the heterogeneous magma structure represented by the macrocryst (porphyry) and aphyric schlieren.

Authors: Khmelkov Alexander , Vlasova Elvira , Ivanov Alexander
Published: November 2021

Studied the composition of garnets from three kimberlite bodies of Nakyn field (Nyurbinskaya and Botuobinskaya pipes, Markhinskaya dyke). Paragenetic specialization of garnets was determined on the basis of their chemical composition with use of the original MineralogicalAnalyse program. This program was specially created for paragenetic classification of kimberlite minerals and is currently capable of recognizing 41 paragenesis by the composition of garnets. The set of paragenetic groups determined by the program most fully characterizes paragenetic diversity of the composition garnets from kimberlites and associated placers to date. A significant difference was established between the kimberlite bodies of Nakyn field, both in the set of different garnet paragenesis and in their percentage. A distinctive feature of garnets this field is the increased content of eclogite paragenesis among them. Xenoliths of metamorphic basement rocks did not significantly affect the paragenetic association of garnets from studied kimberlite bodies. Using of the Mineralogical Analyse program allows one to judge both paragenetic affiliation of garnets and the deep sources of diamonds of specific kimberlite bodies.

Published: November 2021

Urban farming has the potential to utilise unused space in the community to alleviate food shortages and increase the community’s income through local food production. When Internet of Things (IoT) technology is integrated with urban farming, it can further improve its efficiencies and yield. The work in this paper improved our previous work of using an IoT-based climate control system to regulate the cultivation environment of oyster mushrooms automatically. Even though the climate control system could produce two batches of mushroom yields, there were several limitations, such as less efficient climate control due to threshold-based corrective action, water wastage, and system instability. This paper aims to address these stated limitations by implementing a fuzzy logic algorithm and redesigned the climate control system. Two crisp input variables from DHT22 sensors representing temperature and humidity were fed into the Node MCU microcontroller’s fuzzy logic coded in C language. The temperature and humidity conditions were divided into five fuzzy trapezoidal membership functions resulting in 25 fuzzy rules to control the duration of running the water pump and ventilation fan. An internal, lightweight web server were managed all HTTP client requests. The enhanced system also included a safety measurement to avoid overheating the microcontroller and causing water wastage. Upon analysis of the data captured in two months, the result showed a decrease of 40% in water utilisation and an increase of mushrooms yield up to 226%. The enhanced climate control system also facilitated maintaining and controlling the temperature and humidity conducive for optimal mushroom cultivation.
Reduction of the Backing Gas Sequence as a Facile Method to Improve Corrosion Resistance in Duplex Stainless Steel (DSS) Weldment
Authors: Laksono Basuki Tri , Kurniyanto Hendri Budi , Sadewa Purwa , Wirawan Riza
Published: November 2021

Duplex stainless steel (DSS) is an important material used for corrosion resistance in various harsh environment plants such as petrochemical, offshore subsea component, and other chemical industries. An approximately equal amount of austenite and ferrite (A/F) ratio grants good mechanical properties and rust protection on. The detrimental intermetallic phase frequently occurs due to an unbalanced A/F ratio caused by the welding’s thermal cycle. Backing gas is commonly applicable in the field combined Gas Tungsten Arc Welding (GTAW) process. However, the use of backing gas to complete a single weld from root to cap joint required huge additional costs for consumables. Maintaining the thermal cycle in the welding parameter and GTAW process with ER2209 filler metal for DSS below 10 mm thick can reduce the backing gas sequence. The research aims to efficiently substitute full backing gas consumption, which meets a desirable quality in terms of corrosion resistance. The effect of backing gas reduction was studied. All specimens were tested by visua Vickers microhardness, metallography, ferrite content measurement, and electrochemical corrosion test. The visual test shows no defects beyond the range of the ASME IX acceptance and criteria. The evaluation comes from the ferrite scope and electrochemical corrosion test. The backing gas on the root weld shows a balance A/F ratio of around 38% ferrite content accepted in various standards. The backing gas sequence on the root until filler-pass obtained 0.04 mm/year, which is the desirable corrosion resistance and met the requirement of ASTM A932.
Host-Parasitic Relationships between Tetrastigma rafflesiae and Rafflesia azlanii and Rafflesia cantleyi in Belum-Temenggor Forest Complex, Perak, Malaysia
Authors: Sheikh Kamal S­yarifah Haniera , Suratman Mohd Nazip , Khamis Shamsul , Nik Hassan Ahmad Najmi , Mohammad Mohd Syaiful
Published: November 2021

Rafflesia is a holoparasitic plant that depends solely on its host for its nutrients, given that during the early stage of its life, this parasite lives inside the host vine. The lack of host specificity and preference information for Rafflesia can largely be attributed to the absence of a comprehensive taxonomic study in Tetrastigma . Without the host, the Rafflesia will not be able to survive. Therefore, this research was conducted to study the host-parasitic relationships between the two species using anatomical dissection and micrographic images using a light microscope (LM) and scanning electron microscope (SEM). The anatomical study consisted of three stages of Rafflesia buds; the emergence of cupule stage, cupule-bract transition stage, and bract stage ­­attached with the host. All samples underwent sliding techniques and were observed using LM and SEM. Based on the results, the anatomical characteristics of the host-parasite for the cupule stage evidenced penetration of the parasite-affected tissues inside the vascular bundles with the visibility of the flower bud. However, during other stages, the penetration of parasite-affected tissues to the vascular bundles was disrupted and cannot be seen using this sliding technique. The endoparasite of Rafflesia invades the host only towards the phloem region in the early stage. In contrast, in late buds for both species, the Rafflesia tissue invaded both the host xylem (proximal region) and phloem. The parasite intrusion movement for both Rafflesia species showed a pointed tissue towards the host as this was believed to minimise the damage of the host plant. A new method using the paraffin wax technique might improve the sectioning and provide a more precise relationship dissection. The information from this study is expected to provide baseline information and an understanding of the host-parasitic relationship between the species. In addition, further anatomical studies with the different stages of buds will offer a better understanding of their relationship with the host.
Growth of Acacia mangium at Different Stand Ages and Soil Physicochemical Properties in Sarawak, Malaysia
Authors: Nazeri Afifi , Jusoh Ismail , Wasli Mohd Effendi
Published: November 2021

The information on soil physicochemical properties is vital for the optimum wood biomass production in forest plantation management. The objective of this study was to determine the topsoil physicochemical properties under different Acacia mangium stand ages and their effect on the growth parameters. Five plots were established randomly within each five different stand ages. In all sample plots, the diameter at breast height (DBH) and the total height of standing trees were measured. Soil samples were collected at a depth of 0 to 20 cm at three random points in each plot, then mixed to get a composite before determining physical and chemical properties. DBH mean and the total height of A. mangium increased as stand age increased. The mean annual volume increment maximised at the 8.5 years old stand with 27.9 m3 ha-1 yr-1. Survival rate and stem density decreased as stand age increased. Principal component analysis (PCA) results showed that the most important soil physical properties were soil organic matter, silt and sand contents, bulk density, and moisture content. For soil chemical parameters, exchangeable magnesium (Mg), cation exchange capacity (CEC), total carbon (TC), total nitrogen (TN), and carbon-to-nitrogen (C/N) ratio were the influential soil variables. Soil pH, available phosphorus (P), and clay content were negatively correlated with the growth development of A. mangium trees. Observations suggest that multiple soil variables are essential for the success of the A. mangium plantation.

Data protection regulation: a comparative law approach
Authors: Magalhaes MarcusAbreu de
Published: November 2021

This paper aims to present a comparative approach to data protection regulations around the world. Most countries possess data protection laws in some level of detail. In order to compare structures of data control and compliance in dissimilar systems, the study selected four distinct arrangements : the European General Data Protection Regulation (GDPR); the California Consumer Privacy Act (CCPA); the Brazilian Digital Privacy Law, Lei Geral de Proteção de Dados Pessoais (LGPD); and the Chinese Data Privacy Framework, which is molded by a set of different regulations.
The analysis was based in common key points of those regulations – territorial scope, consent and disclosure, data security requirements, data transfer, Data Protection Officer, awareness and training, and penalties – to explore the different policies and national goals. The paper argues that, in the landscape of the information based society, new law is needed to protect citizens’ rights to privacy and to bound harvesting and mining of personal information to ensure transparency, control, and compliance of the information economy.

Technological development has extremely useful facets for everyday life, since disruptive innovations are increasingly present in society. In this current scenario, the State's intervention in the economy is increasingly difficult. The objective of this research is to investigate the regulatory role of the Executive Power and regulatory agencies regarding streaming technologies. To do so, initially, the paper investigates the definition of streaming services, analyzing their legal adequancy according to Brazilian legislation. Subsequently, the regulatory competence of the Ministry of Science, Technology, Innovation and Communication, the National Telecommunications Agency and the National Cinema Agency in relation to new technologies for dispersion of audiovisual content is analyzed. In the end, it is concluded that it is the responsibility of MCTIC to be the granting power of broadcasting services, not interfering in streaming services. Anatel is responsible for regulating the conditions and the relationship between streaming and telecommunications service providers, in this case, the internet, as well as assuring them the right to use the internet infrastructure. Ancine is responsible for acting with the objective of promoting, regulating and supervising the cinematographic and videophonographic industry in the various market segments. The research methodology used is the hypothetical-deductive and research technique is indirect documentation.

A burn is a type of injury to the skin or other tissues. It can give rise to skin defects or even death. In this study, sponges derived from amnion hydrogel were generated to apply as a wound dressing. The sponges were created by combining crosslinking and freeze-drying methods. There were three types of the obtained sponges: MGA-0 (only washed with PBS), MGA-1 (washed in glycine 1 % for one day) and MGA-2 (washed in glycine 1 % for two days). These sponges were evaluated by scanning electron microscope (SEM), mechanical test, swelling, and cytotoxicity. The tensile strength of the sponges was about 1.8 MPa, and the absorption increased during 24 h. The relative growth rates (%RGR) of MGA-0, MGA-1, and MGA-2 were 88.8, 58.2 and 67.2 %, respectively. The obtained results suggested that the MGA-0 sponge has potential for wound dressing application.
HIGHLIGHTS

The sponges have been manufactured from human amnion hydrogel by combining crosslinking and freeze-drying methods
Through the scanning electron microscope (SEM), the surface of the obtained sponges showed a fibrous-like structure
These sponges have good absorbency, the tensile strength of the sponges is about 1.8 MPa like the tensile strength of human skin, and the MGA-0 sponge is not cytotoxic

GRAPHICAL ABSTRACT
Laser Hardening of Unimax Stainless Steel

Nowdays, laser hardening of materials brings a comparative advantage over the conventional hardening technique. Fast cooling rate due to the heat distribution through its own bulk material, self-quenching property (rapid cooling without external water or oil), environmentally friendly characteristics since the procedure does not exhaust smoke, the localized heat input due to adjustable laser spot size to avoid distortion and minimum time to finish the operation are some of the advantages to mention. NIKO is a company specialized in making electrical products like socket outlets and switches by using injection molding techniques. Unimax is a kind of stainless steel used by the company to prepare some parts of the injection molding components like a Nozzle. This time, the company is using more and more fiber-reinforced polymers throughout their product line. These composites are far stronger than the polymer, but on the downside, the fibers are quite abrasive. The objective of this research was to harden the Unimax stainless steel using Nd:YAG (neodymium-doped yttrium aluminum garnet) laser technique. First, the laser transverse speed and spot size were identified as the primary process parameters. Then, the traverse speed of 100, 150 and 400 mm/min and spot size of 2164, 2169, 2288 and 2412 um were assigned with 3 replications. Afterwards, thermal simulation was done using COMSOL Multiphysics© followed by the real test on the metal bar. Therefore, the highest hardness of 650 HV was obtained at a speed of 150 mm/min and a spot size of 2169 um diameters. Finally, the corresponding depth of hardness and roughness values of 200 um below the surface and unmelt samples respectively were obtained.
HIGHLIGHTS

Laser hardening of materials brings a comparative advantage over the conventional hardening technique
The laser transverse speed and spot size were identified as the primary process parameters. Afterwards, thermal simulation was done using COMSOL Multiphysics© followed by the real test on the stainless steel bar
The depth of hardening and Vickers hardness (HV) increased with the smaller spot size and slow traverse speed of the ND:YAG laser, but this resulted in a melt on the surface of the hardened metal
One of the problems of making products using injection molding techniques using fiber-reinforced polymers is the abrasive nature of the fibers which widen the injection nozzle
