The Mentoring’s Role among Alumni Students of István Wáli Roma College for Advanced Studies of the Reformed Church
Authors: Godó Katalin , Ceglédi Tímea , Kiss Andrea
Published: April 2020

Colleges for Advanced Studies (CASs) are the oldest institutionalized talent development initiatives of higher education in Hungary (since 1895). The Act CCIV of 2011 on National Higher Education initiated the creation of a national network of denominational Roma CASs. In a CAS, students live in a dormitory, build a strong community, get scholarships and support from tutors and mentors. Important elements of Roma CASs are the following: religious education, social responsibility for society, and Roma identity empowerment (Godó et al., 2019; Kardos, 2013; Charta, 2011). In this study, we examined alumni (ex-university students) of a Roma CAS in Debrecen. Among other things, we were interested in how they relate to the mentoring process, how they feel about it, and how mentoring is perceived in their own lives. We are also interested in what types of mentors are mentioned and whether there is any form of mentoring in their current activities. Method of our research: qualitative interview analysis. Semi-structured interviews were conducted in 2018 with 17 alumni selected by snowball method. According to our results, the former students named 2 types of mentors who were next to them: layman and professional mentors, or they themselves can be typed as mentors on the basis of the following: layman mentors (layman persons involved in mentoring activities) and professional mentors. We consider it important to emphasize the role of the pastor in a Reformed institution, who has also been promoted to the professional mentoring category. In addition, our goal is to investigate the characteristics of networking patterns that emerge around specialist college students.
The perspectives of the doctoral students of the University of Debrecen related to migration
Authors: Szigeti Fruzsina
Published: April 2020

Research on migration processes in recent years has highlighted the fact that migration is becoming more common among younger and more educated people. We believe that it is worth meeting the (self)selection of (potential) migrants at the beginning of the process, and also, measuring the willingness to migrate is important. During our research, we investigated the migration plans of PhD students at the University of Debrecen through paper-based questionnaires. In our study, we seek to determine the extent to which PhD students in Debrecen are willing to migrate. Also, we investigate what the fundamental difference is between PhD students with the intent of migration and those without. 53.4% of the responding doctoral students intend to stay in Hungary after completing their doctoral training, while 46.6% consider it possible to settle abroad. It has been observed that strong and weak bonds of those who wish to stay in the country of residence are significant, while those who wish to stay abroad own migration shells.

Authors: Kasler Jonathan , Shavit Ayelet , Michaeli Harel Nofar , Sharabi-Nov Adi
Published: April 2020

The aim of this study was two-fold. First, we sought to map the personal moral compass (PMC) of children in the periphery – girls and boys, Palestinians and Jews - to better understand how nationality and gender affect their values – as activated in their lives. Second, we examined the relationship between personal moral compass and measures of well-being. 1001 children aged 12-13 years living in the geographic northern periphery of Israel, were asked to write short compositions on enactment of their values and complete questionnaires on their sense of hope, general belongingness, and life engagement. In choice of values, clear differences between Palestinians and Jews were revealed, but gender differences were less salient.  We also found that Palestinian and Jewish girls mentioned values more often and demonstrated deeper commitment to their PMC than boys did. Examining personal moral compass emerged as a valuable tool to learn about children’s inner world.

Theodor Fontane zum 200. Geburtstag
Authors: Rüther Günther
Published: April 2020

Fontane war ein Mann der Gesinnung und Haltung, aber kein Prinzipienreiter. Vielmehr strebte er nach Kompromissen, die er auch in seinen Texten geltend machte. Sein Leben und Werk sagt uns sehr viel darüber, worauf es im Zusammenwirken einer Gesellschaft ankommt: Respekt vor dem anderen und die Einsicht in die eigene Unvollkommenheit. Der Aufsatz analysiert die Texte vor der Folie dieser Haltung und bleibt dabei bei der eindrucksvollsten Frauengestalt in Fontanes Werk, Gräfin Melusine stehen, deren Gestalt sich als Manifest des humanen Zusammenlebens deuten lässt.

Quest for Better Technology: Case of Brown Coir Fibre Industry in Sri Lanka
Authors: K. V. N. N. Jayalath  , U. K. Jayasinghe-Mudalige
Published: April 2020

The purpose of this study was to assess the impact of a number of attributes (a = 23) upon 5 major factors (Labor, Land and Capital, Machine, Technical and Market) that influence a selection of a particular technology to manufacture brown coir fibre in Sri Lanka (i.e. Sri Lankan Drum Pairs, Defibering Machine, D1 Machine). A cross section of owners of fibre mills (n = 30) located in the Kurunegaka, Puttlam and Gampaha districts were selected and a personal interview with each mill owner was carried out with the help of a structured questionnaire from May to June 2008 to collect data. The Semantic Differential Analysis techniques were employed to find the relative strength of the attributes of 5 factors considered in the analysis, where the responses were recorded on a seven-point bipolar scale. The “XLStat” software was used extensively to plot the relationships between the 23 attributes and 3 technologies.

The results suggest that all three technologies are negatively perceived by the coir fibre millers on land and capital, and machine subsets. Further millers had negative perception on attributes related to labor subset of Sri Lankan Drum Pair technology. However, they hold the view that high quality of the bristle fibre extracted by this machine is not comparable with that extracted using any other technologies. The millers’ perception on technical and market attributes of the three different technologies was better than on other attributes.

The results imply that policymakers should, more specifically, take into account the issues related to capital, machine and labor as they advise coir fibre manufactures about possible technology transfer, in order to avoid potential failures in these markets (i.e. plant-exit) and government policy (i.e. non-compliance).
Biological Studies on Dipha aphidivora Meyrick (Pyralidae: Lepidoptera): A Potential Predator of Coconut Mealybugs in the Philippines
Authors: J.C. Orense  , M.L.R. Imperial
Published: April 2020

Dipha (Conobathra) aphidivora Meyrick (Pyralidae: Lepidoptera) is recorded for the first time as a predator of coconut mealybug, Sangicoccus sp. (Eriococcidae: Homoptera)) in the Philippines.  Some aspects of its biology and ecology were studied to determine its suitability as a biological control agent against Sangicoccus sp.

The life history of D. aphidivora was investigated following the establishment of a rearing procedure. The incubation period of the egg was 4.64±0.70 days. The four larval instars larva were completed in 5.52±0.92, 3.40±0.91, 2.83±0.72 and 3.40±1.04 days, respectively. Adults emerged from pupae after 7.68± 0.99 days.  Adult longevity was 6.83 ± 2.30 days. The life cycle of D. aphidivora lasted for 32.42±3.63 days.

Voracity tests showed that the four larval instars of the predator consumed an average of 150 mealybugs.
Coconut Palms on the Edge of the Desert: Genetic Diversity of Cocos nucifera L. in Oman
Authors: Lalith Perera
Published: April 2020

In the Gulf region, coconuts are almost exclusively produced from palms growing in the Sultanate of Oman, particularly in the extreme south-eastern coastal plain of the Dhofar Governorate, and specifically within the city limits of Salalah, between the Jebel and the sea. The importance of these coconuts is not only agricultural; historically, the Dhofar palms provided the basic materials to build boats for fishermen and traders on, around and eventually beyond the Indian Ocean. Coconut palms are now one of the main symbols of Salalah city and play a role in both the tourist industry and urban landscaping. In early 2009, twenty-nine sites, representing Oman coconuts on beaches and cultivated lands were chosen from the Dhofar region. COGENT descriptors and DNA analysis were used for the purpose of identifying coconut germplasm available in Oman. The presence was confirmed of varieties that were imported during the 1980s, such as Yellow Dwarf, Green Dwarf and King coconut from Sri Lanka, as well as Malayan Yellow Dwarf and F1 hybrids. The local Oman Tall has the same phenotypic characteristics as other coconuts of South Asia, East and West Africa, the Caribbean and the Atlantic coast of South America. Microsatellite markers, however, reveal a substantial genetic contribution of the South-East Asian coconuts, at levels that are comparable to those found in the Comoros and Madagascar coconuts. Hypotheses about the ancestry of the Oman Tall coconuts are discussed; two genepools are indicated, consecutively involving natural selection, dissemination by floating, domestic selection and dispersal by boat.

Published: April 2020

Bio composting process is the available means of converting various organic wastes generated from the industry and the agricultural sectors into beneficial products such as biofertilizers and as a soil conditioners. The unique feature of these agricultural wastes are their organic content, pH, and high C: N ratio. Coir pith is a biomass residue obtained during the extraction of coir fibre from coconut husk. Accumulation of coir pith leads to an environmental concern and its management is a major problem with all coir industrialists. The high quantum of its production and the difficulties experienced in its disposal have tended to create a major problem of pollution of large areas of land and water in coir fiber extraction units. Therefore, biodegradation of coir pith is an essential requirement to control pollution. Coir pith, even though a problematic waste; it is a potential wealth when it is converted into valuable organic manure by microbial degradation. A method of composting of coir pith with urea has been developed by Coir Board, India using a fungus viz., Pleurotus sajor caju commercially known as Pithplus.  

            Application of urea releases higher concentration of ammonia in the soil making it more acidic and retards soil natural fertility. Hence an alternative cost effective nitrogen supplement needs to be developed as a substitute to urea for composting of coir pith. The present study aims at the formulation of bio organic manure from coir pith avoiding inorganic urea in the composting. Overall assessment on the physico chemical properties of the biodegraded coir pith leads to the conclusion that a combination of Azolla and Soya hulls (2:1 ratio) was found to be efficient in lignin degradation and contribute to novel changes in coir pith
Do Belief Differences Lead to Change in Behavior? A Study of Sri Lankan Coconut Farmers
Authors: C. S. Herath
Published: April 2020

Technology adoption by farmers is an important factor in agricultural development in both developing and developed countries that has not been achieved over the past years. The level of technology adoption is highly dependent on farmers’ beliefs and attitudes. Therefore, adoption studies are important to identify beliefs and attitudes of farmers that affect decision making. The present study tries to explain and identify the effect of motivation on farmers’ behavior to acquire knowledge and what are their beliefs and motives that underlie adoption of technology. The theory of planned behavior provides a structure to identify farmers’ behavioral intention with respect to attitudes, subjective norms and perceived behavioral control. The Self Determination Theory provides an explanatory system for the understanding of the motivation behind volitional behavior. These two theories serve as the key methodology for the study. The results revealed that, farmers’ participation in technology dissemination programmes and their willingness to gain information and skills have a significant relationship with intrinsic motivation. Further, those farmers hold positive beliefs towards new technology adoption and innovations. Therefore, two types of extension approaches are needed to enhance the technology adoption for intrinsically motivated and extrinsically motivated farmers.
Improving Income from Coconut Cultivation through Farm Level Value Addition – An Analysis
Authors: P. Anithakumari
Published: April 2020

Coconut cultivation in India is mostly in small and marginal land holdings. Farm level coconut processing for value addition is one of the options for risk reduction and improving the income from such holdings. This study was conducted during 2009-10 with the objectives of analyzing the profile of farm level processors as well as the constraints faced by those who have adopted minimal processing at the farm-household and community levels. It was found that 63.3% of the respondents were of middle age group, literate, low income group and 80% of them were women. The experience in coconut value addition was for 8 years or less. Further, the entrepreneurship behavior of the respondents was found to be positively and significantly correlated with the credit availed, annual income and investment made. The analysis on the utility of the training programmes indicated  need for reorientation of training curricula in terms of project preparation techniques, communication/marketing  skills etc. The value addition obtained per nut was found to vary from Rs.0.5 to Rs.15 depending on the products. The constraints and suggestions for improving farm level value addition were also furnished as perceived by the respondent farmers. The study showed that there is tremendous potential for farm level value addition for utilizing the marketable surplus of coconut locally. The importance of providing further technical support to those involved in value addition was also revealed by the study.
In Vitro Characterization of Indigenous Coconut Varieties (Cocos nucifera L.) of Sri Lanka for Water Stress Tolerance
Authors: L Perera
Published: April 2020

Coconuts show a remarkable yield drop due to long dry periods caused by global climatic changes. Thus, breeding for drought tolerance has become a priority in coconut breeding in Sri Lanka. Five coconut varieties indigenous to Sri Lanka, namely Ran thembili, Gon thembili, Porapol, Bodiri and Red dwarf were screened for their drought tolerance potential in vitro. Mature zygotic embryos collected from self pollinated nuts of each variety were germinated and developed into plants with one photosynthetic leaf in Y3 medium. Water stress condition was induced by application of Polyethylene Glycol (PEG) into the culture medium. The level of PEG in culture medium was gradually increased from 2% to 7% until the plants showed water stress symptoms in leaves; yellowing and necrosis. More than 75% of zygotic embryos of all tested coconut varieties successfully germinated in vitro and developed into plants. Plants of all tested coconut varieties survived water stress caused by 4% to 6% PEG and the percentages of plant survival at different levels of PEG varied among different coconut varieties. Variety Ran thembili showed the highest survival rate (27%) at 6% PEG and overall best plant growth performances at 4% PEG among the five coconut varieties tested. Red dwarf showed the lowest survival rate at 4% to 6% PEG indicating its susceptibility to water stress. Among the coconut varieties tested, zygotic embryos of Ran thembili showed the highest drought tolerance potential.

Authors: Rizal Alamsyah
Published: April 2020

Study was conducted on coco peat as a low emission pellet form biomass fuel alternative to produce synthetic gas (syngas) through gasification process in use for other processes. Coco peat was first screened and formulated with other materials such as coco peat, starch, and waste cooking oil. These materials were mixed and pelletized using a pelletizer to form coco peat pellet. It was burned on an updraft gasifier to produce synthetic gas (syngas) and then streamed to a stove through a pipe. The syngas was then split and burned and the heat generated was used for boiling water and for drying agricultural products.  Air quality around the stove (emission test) was measured and analyzed when gasification took place. The best results of coco peat pellet were made from 85% of coco peat waste, 5% starch (binder), and 10% of waste cooking oil with stronger texture and shiny surface. The experimental gasification using updraft gasifier exhibited better result when half of the volume of gasifier was filled with 5 kg pellet and the syngas produced can be used for 3.5 hours drying and boiling. Air quality surrounding the stove was tested during gasification process. It was done based on the Indonesian Environmental Regulation issued by Indonesian the Ministry of Environment on Standards (KEP-13/MENLH/3/1995 dated March 7th, 1995) regarding standard air quality from static matter and covers NH3, Cl2, HCl, HF, NO2, particles, SO2 and H2S parameters.  The result of measurements indicated that all parameters meet the quality standards) including CO and CO2 at 0.0001 mg/kg.

Authors: Geethanjali Kanagaraju
Published: April 2020

Knowing the magnitude of therapeutic plants such as Micrococca mercurialis (MM), Abutilon palmeri (AP) and Callistemon citrinus (CC), we also planned to extend our research work on Cocusnucifera fibers (CF) and dust (CD) as it has copious medicinal properties. The current study deals with the green synthesis of silver nanoparticles (AgNPs) from fresh aqueous extracts and AgNO3 solution. The biogenic conversion of silver ion to silver is relatively expeditious at two different time intervals and pH. The isolated  silver nanoparticles (AgNPs) from the bio extracts were identified initially by scrutinizing the colour variations. The biosynthesized AgNPs were characterized by UV, XRD, Laser Diffraction Particle size Analyser, fluorescence spectroscopy, SEM and TEM. UV absorbance at 435-460nm for silver nanoparticles was observed for the above extracts. The XRD pattern of all extracts showed the distinctive Bragg peaks of face centre cubic (fcc) crystalline system available in nature. SEM and TEM analysis of the silver nanoparticles indicated that the particle size was in the range of 2-100nm with polygonal and spherical shapes. The biosynthesized AgNPs were evaluated for antimicrobial activities. The CFAgNPs showed an efficient antibacterial activity at lower concentration (25mg/ml) against Pseudomonas demolytica followed by Staphylococcus aureus and Escherichia coli. Similarly all plant extracts have better activity against fungal strains. It is concluded that the biogenic blend of AgNPs is simple, extremely rapid, beneficial, eco-friendly and more stable without any toxic effects. Of these, CFAgNps may be used for the preparation of antibacterial groupings against Pseudomonas demolytica and Staphylococcus aureus.

Published: April 2020

The quality of coconut chips can be increased, through efforts to improve processing by immersing the coconut meat in CaCl2 solution. The various concentrations of CaCl2 solution are 0.0%, 0.5%, 1.0%, 1.5%, and 2.0%. Furthermore, the effect of treatments was evaluated on the characteristic of coconut chips for 0 months, 2 months, 4 months, and 6 months of storage in plastic coated aluminum foil packaging. The results showed that coconut chips from DMT coconut meat with fruit 9 months old contain 2.36-2.49% moisture, 2.36-2.55% ash, 3.87-5.35% protein, 37.31-45.35% fat, 50.15-53.23% carbohydrate and 4.93-5.48% crude fiber. Immersion in CaCl2 solution and storage time increased the water content of coconut chips. The results of organoleptic testing showed that coconut chips still preferred by respondent up to 6 months of storage. The higher concentration of CaCl2 solution was used, resulting in smaller pressure (gram force) to break or destroy coconut chips, which can be interpreted that coconut chips have a crispness that is still good. Next, the color measurement uses Chromameter Konica Minolta CR-400, L (Lightness) value to 6 months ranged from 76.39-77.65, which indicated that the color of the product is still predominantly bright white.

The mathematical or economic approach to the effect that culture exerts on its consumer is less common. The present paper refers to a new cultural genre in Romania, the oldest in the world, the genre of Japanese animation, called "anime", which developed externally and internally a true market of its derived products. Lovers of this kind of animation are called "anime fans," and our research respects a cognitive pattern related to their identity. Exogenous influences with an implication in the consumer's decision are of particular importance in this respect. The study of their dynamics in the context of research applies to any decisional behavior.
Evaluation of Magnetic Parameters and Kinetics of the Magnetic Nanoparticles in High Magnetic Fields and its Potential Applications
Authors: Arokiaraj Mark Christopher , Liubimtcev Aleksandr
Published: April 2020

BACKGROUND: Multifunctional nanoparticles are known for their wide range of biomedical applications. Controlling the magnetic properties of these nanoparticles is imperative for various applications, including therapeutic angiogenesis. AIM: The study was performed to evaluate the magnetic properties and their control mechanisms by the external magnetic field.
METHODS: A100 nm magnetic nanoparticle was placed in the magnetic field, and parametrically, the magnet field strength and distance were evaluated. Various models of magnetic strength and disposition were evaluated. Magnetic flux density, force/weight, and magnetic gradient strength were the parameters evaluated in the electromagnetic computational software.
RESULTS: The seven-coil method with three centrally placed coils as Halbach array, and each coil with a flux density of 7 Tesla, and with a coil dimension of 20 cm × 20 cm (square model) of each coil showed a good magnetic strength and force/weight parameters in a distance of 15 cm from the centrally placed coil. The particles were then evaluated for their motion characteristics in saline. It showed good displacement and acceleration properties. After that, the particles were theoretically assessed in a similar mathematical model after parametrically correcting the drag force. After the application of high drag forces, the particles showed adequate motion characteristics. When the particle size was reduced further, the motion characteristics were preserved even with high drag forces.
CONCLUSION: There is potential for a novel method of controlling multifunctional magnetic nanoparticles using high magnetic fields. Further studies are required to evaluate the motion characteristics of these particles in vivo and in vitro.

Immediate high-quality cardiopulmonary resuscitation (CPR) and early defibrillation are essential to survival, yet CPR skills deteriorate without frequent repetition. Basic Life Support-focused Code Blue team-based simulation is needed in continuing education to bridge this gap. This article outlines a teaching plan for hospital orientation and subsequent scenarios to improve the resuscitation response.

Authors: Li Xiangfeng , Zhao Hong , Guo Aimin , Tudor Carrie , Tian Ce
Published: April 2020

Background:

This study evaluated the effects of the Training-for-Transformation (TFT) program on tuberculosis (TB)/multidrug-resistant TB (MDR-TB) in China.

Method:

Participants who received training from 2009 to 2017 (
n
= 230) were invited to complete an online survey using a self-designed questionnaire.

Results:

A total of 130 (56.5%) trainees completed the survey for a valid response rate of 70% (91 of 130). All of the participants created a schedule and offered a TFT program on TB/MDR-TB for health care providers, clients, and communities by a variety of methods that included brainstorming, group work, and role-play, in addition to lectures. The most important supporting factors to train others were related to opportunity and managers' support, and the biggest barriers were lack of space and time. Trainees also made changes to practices that influenced the way nurses worked within their institution, infection control, team cooperation, extended care, and nurses' attitudes toward patients.

Conclusion:

The TFT program led to ongoing training provision and practical improvements, and can transform attitudes, practices, and changes in patient care.

Detection of Occult Arteriovenous Malformation With Annular Array Ultrasonography
Authors: Ledesma-Gil Gerardo , Essilfie Juliet , Freund K. Bailey , Yannuzzi Lawrence. A , Fisher Yale L.
Published: April 2020

Retinal vascular tortuosity may occur in a wide range of ocular disorders. When retinal vascular tortuosity involves both arteries and veins, and presents unilaterally and without hemorrhage, a diagnosis of Wyburn Mason syndrome (WMS) should be considered due to the potential morbidity and mortality associated with cerebral involvement. Magnetic resonance imaging (MRI) and MRI angiography (MRA) are important tools for identifying cerebral arteriovenous malformations (AVMs), but these imaging modalities have limited spatial resolution to detect very small vascular lesions. Annular array contact ocular ultrasound is a new imaging modality capable of detecting small intraorbital AVMs.

Published: April 2020

Globe perforation following retrobulbar or peribulbar anesthetic injection is a rare but dreaded complication that often results in suboptimal visual outcomes. This video describes a 72-year-old woman who sustained a globe perforation during retrobulbar block in the setting of cataract extraction and later developed a retinal detachment. The retina was repaired with pars plana vitrectomy and silicone oil, resulting in a favorable visual outcome. The authors discuss various modes of local anesthesia for vitreoretinal surgery, risks for globe perforations, and how to approach retinal detachment secondary to needle perforations, which are complex cases at high risk for proliferative vitreoretinopathy.

U na de las vías teóricas para la movilidad social. El riesgo que eso comporta es reducido por medio de una serie de estrategias, relativas tanto a la adopción de uno u otro rol en el juego como a la formación de grupos.
Using Environmental DNA to Monitor the Spatial Distribution of the California Tiger Salamander

Published: April 2020

Global efforts to conserve declining amphibian populations have necessitated the development of rapid, reliable, and targeted survey methods. Environmental DNA surveys offer alternative or complementary methods to traditional amphibian survey techniques. The California tiger salamander Ambystoma californiense (CTS) is endemic to California, where it breeds in vernal pools. In the past 25 y, CTS has faced a 21% loss of known occurrences, largely through habitat loss, and it is threatened by hybridization with an introduced congener. Protecting and managing remaining CTS populations rely on accurately monitoring changes in their spatial distribution. Current monitoring practices typically use dip-net surveys that are time-consuming and prone to false negative errors. To provide a new resource for monitoring and surveying larval CTS, we designed an assay and tested it on water samples collected from 29 vernal pools at two locations in California. We compared environmental DNA results to contemporaneous dip-net surveying results and found the assay agreed with positive dip-net results in 100% of cases. In several instances, we also detected the presence of CTS genetic material in the early spring before larvae hatched, potentially offering a new, earlier detection option for this imperiled species. This assay provides a valuable, noninvasive molecular tool for monitoring the spatial distribution of the CTS in vernal pools.

The conversion of Ceiba pentandra oil to catalytic hydrocracking are suitable ways for biofuel. The focus of this study is to use Ceiba Pentandra oil catalytic hydrocarbon cracking and determine the alternative to petroleum fuels. The conversion of the Ceiba pentandra oil was carried out using a batch reactor, type 4563 PARR with a volume of 200 ml. This conversion process is done by varying the temperature factor (300-400°C), the reaction time over the range of 30-120 minutes and hydrogen pressure over a range of 30 bars using NiMo/HZSM-5. The conditions for the highest conversion of gasoil (C15-C18) as much as 43.78% were temperature of 400 minutes. The same conditions for kerosene (C9-C14) and long hydrocarbon chains (>C18) were present at 4.93% and 2.85% respectively. The kinetic study was determined to determine the order and kinetic parameters of activation energy (Ea) of 84,266 kJ.kgmol-1K-1 and the exponential factor from the Arrhenius relationship. The order of this reaction has been determined of the first order and the kinetic model is defined as . Ceiba pentandra oil triglycerides hydroconversion pathways were dependent on temperature and reaction time. The triglycerides could be hydrocracked to lower range hydrocarbons (C9-C14) by increasing the reaction temperatures.

Ti-6Al-4V alloy have been used widely for biomedical application, but its elastic modulus is still higher compared with human bone. Moreover, it contains V and Al that have been reported as toxic element. In this study new beta type Ti-6Mo-6Nb-xSn (0, 4, 8 wt.%) have been developed. The aim of this study was to evaluate the Sn addition on microstructural transformation, mechanical behaviour, and corrosion resistance of Ti-6Mo-6Nb-xSn alloys. The Ti-6Mo-6Nb-xSn alloys produced by arc re-melting process and the obtain ingot were characterized using optical microscope, x-ray diffractometer, ultrasonic evaluation, Vicker’s hardness tester, and polarization test to evaluate the corrosion resistance. The result showed that Ti-6Mo-6Nb-8Sn has the lowest elastic modulus and Vicker’s hardness value. The Sn addition could suppress α phase formation. Ti-6Mo-6Nb-8Sn has lower corrosion rate compared to commercial Ti6Al4V.

Published: April 2020

Let $X,Y$ be two Hilbert spaces, let E be a subset of $X,$ and let $G\colon E \to Y$ be a Lipschitz mapping. A famous theorem of Kirszbraun’s states that there exists $\tilde {G} : X \to Y$ with $\tilde {G}=G$ on E and $ \operatorname {\mathrm {Lip}}(\tilde {G})= \operatorname {\mathrm {Lip}}(G).$ In this note we show that in fact the function $\tilde {G}:=\nabla _Y( \operatorname {\mathrm {conv}} (g))( \cdot , 0)$, where $$\begin{align*}g(x,y) = \inf_{z \in E} \Big\lbrace \langle G(z), y \rangle + \frac{\operatorname{\mathrm{Lip}}(G)}{2} \|(x-z,y)\|^2 \Big\rbrace + \frac{\operatorname{\mathrm{Lip}}(G)}{2}\|(x,y)\|^2, \end{align*}$$defines such an extension. We apply this formula to get an extension result for strongly biLipschitz mappings. Related to the latter, we also consider extensions of $C^{1,1}$ strongly convex functions.
