Rht24 is a major dwarfing allele that not only reduces plant height but also increases grain weight. The objective of this study was to trace the source, spread, and distribution of Rht24 and determine its frequency in conjunction with other important dwarfing alleles for Rht1 (Rht‐B1b), Rht2 (Rht‐D1b), and Rht8. Allele‐specific cleaved amplified polymorphic sequence (CAPS) markers were developed for accurate and effective genotyping of Rht1 and Rht2, and closely linked flanking markers were used for genotyping of Rht8 and Rht24. Marker analysis showed that Rht24 occurs at a higher frequency (84.2%) than other important dwarfing alleles in elite wheat (Triticum aestivum L.) varieties and usually couples with Rht2 or Rht8. Genotyping of old varieties and landraces showed that Rht24 was widely used in wheat breeding before the Green Revolution (GR). ‘Akakomugi’ and ‘Norin 10’, the donors of Rht8 and GR genes Rht1 and Rht2, respectively, harbored Rht24, so Rht24 likely followed the transfer routes of GR genes and Rht8 to spread worldwide. Pedigree analysis showed that many Chinese elite lines and backbone parents were derived from Akakomugi, contributing to the high frequency of Rht24 in Chinese varieties. Additionally, Norin 10‐derived semidwarf varieties from the CIMMYT were widely used in Chinese wheat breeding. Finally, Rht24 was also detected in 30 old Chinese varieties and landraces. Overall, these findings show that the presence of Rht24 in modern Chinese elite varieties originated from Akakomugi, Norin 10, or Chinese landraces. Thus, Rht24 was introgressed early, spread widely, and became genetically fixed in a wide range of modern Chinese wheat germplasm.

Published: January 2019

Shading and N fertilization affect fruit distribution in cotton (Gossypium hirsutum L.), but there is no detailed information on earliness of crop maturity according to phenological development. The aim of this work was to evaluate the effect of shading at early flowering and N top‐dressing rates on relative cotton earliness using plant mapping. Field experiments were conducted in Itapeva (16 d of shading; and 0, 60, 120, and 180 kg N ha−1) and Chapadão do Sul (17 d of shading; 0, 80, and 160 kg N ha−1; and early‐ and full‐season cultivars), Brazil. Seed cotton yield was grouped by phenological position (PP) according to the standard phenological scale, for interpolation calculation at each 10% increment in accumulated harvestable yield (Ac), weighted average PP (PPwa) determination, and logistic‐regression analysis. Crop maturity earliness was predicted based on the reduction in PPwa and in PP. Shading increased PP up to 10 and 30% of Ac due to a decrease of 33 and 40% in the number of bolls on early fruiting sites in Itapeva and Chapadão do Sul, respectively, but did not affect PPwa. Increases in PP up to high Ac percentages and in PPwa values were observed at the two higher N rates in both experiments, mainly due to lower and higher boll number at earlier and later fruiting sites, respectively. Short‐term shading during early flowering of cotton changed yield distribution by decreasing boll number on early fruiting sites, but did not affect the earliness of crop maturity. Earliness was decreased by high N rates due to higher cumulative seed cotton yield at later fruiting sites.

Published: January 2019

Cassava (Manihot esculenta Crantz) grown in upper paddy fields after rice (Oryza sativa L.) could increase cassava yield and improve land use efficiency. The objective of this study was to evaluate growth, yield, and starch content of four cassava genotypes grown after the harvest of rice in upper paddy fields in Thailand. Four cassava genotypes—cultivars Kasetsart 50, Rayong 9, and Rayong 11—and line CMR38‐125‐77 were evaluated during the 2015–2016 and 2016–2017 growing seasons for five environments. Each experiment had a randomized complete block design with four replications. Soil characteristics were assessed prior to planting, and crop growth and development and local weather conditions were recorded during the experiments. Environment affected all traits, but genotype and genotype × environment effects were nonsignificant for starch content at 180 d after planting (DAP) and for leaf growth rate (LGR) at 120 to 180 DAP. Average storage root dry weights across five environments were 4301, 3933, 3128, and 5824 kg ha−1 for Kasetsart 50, Rayong 9, Rayong 11, and CMR38‐125‐77, respectively. CMR38‐125‐77 was the most stable genotype for storage root fresh and dry weights, and total dry weight. Physiological determinants of both storage root yield and total biomass of cassava were crop growth rate (CGR) and net assimilation rate (NAR) for 30 to 90 DAP and LGR, stem growth rate (SGR), CGR, and NAR for 120 to 180 DAP, as well as storage root growth rate (SRGR) for 90 to 180 DAP. Leaf growth rate during 120 to 180 DAP is likely to be a new criterion for supporting cassava varietal selection. This investigation showed the feasibility of growing cassava between paddy rice seasons.
Instructors' Perceptions of Networked Learning and Analytics | Perceptions des instructeurs quant à l'apprentissage et l'analyse en réseau
Authors: Comber Scott , Durier-Copp Martine , Gruzd Anatolity
Published: January 2019

This study seeks to understand instructors’ perceptions of social network analysis (SNA) and network visualizations as learning analytics (LA) tools for generating useful insights about student online interactions in their class. Qualitative and quantitative data were collected from three graduate courses taught at a Canadian university at the end of the academic term and came from two sources: (1) class-wide forum discussion messages, and (2) interviews with instructors regarding their perceptions of student networks and interactions. This study is unique as it focuses on instructors’ self-assessments of online student interactions and compares this with the SNA visualization. The difference between instructors’ perceptions of social network interactions and actual interactions underlines the potential that LA can provide for instructors. The results confirmed that SNA and network visualizations have the potential of making the “invisible” visible to instructors, thus enhancing their ability to engage students more effectively.Cette étude vise à comprendre les perceptions des instructeurs sur l’analyse des réseaux sociaux (ARS) et la visualisation de réseaux comme outils d’analyse de l’apprentissage (AA) produisant des perspectives utiles sur les interactions en ligne des étudiants de leur classe. Des données qualitatives et quantitatives ont été collectées dans trois cours des cycles supérieurs d’une université canadienne à la fin de la session scolaire. Ces données proviennent de deux sources : (1) les messages du forum de discussion de l’ensemble du groupe et (2) des entretiens avec les instructeurs au sujet de leurs perceptions sur les réseaux et interactions des étudiants. Cette étude est unique en ce qu’elle se concentre sur les auto-évaluations des instructeurs portant sur les interactions étudiantes en ligne, et les compare à la visualisation de l’ARS. La différence entre les perceptions qu’ont les instructeurs des interactions sur les réseaux sociaux et les interactions réelles souligne le potentiel que l’AA peut offrir aux instructeurs. Les résultats ont confirmé que l’ARS et les visualisations de réseaux ont le potentiel de rendre « l’invisible » visible pour les instructeurs, améliorant ainsi leur capacité à motiver les étudiants plus efficacement.

Authors: Browne Tom , Lyle John
Published: January 2019

This exploratory case study evaluates the implementation and use by student coaches of an innovative coaching profiling system, Touch Screen Technology (TST), to assess coaching behaviours. The study was designed to evaluate the potential of this technologically-enhanced assessment system as a profiling option for gathering, storing, retrieving, and presenting data about coaching competences. The case study documents and evaluates trainee coaches’ (N=100) experiences of using TST during an internship, identifying the advantages and challenges of implementation, and evaluating the potential for coach education and development. Evidence was triangulated from questionnaires, journals, and interviews (N=20). The responses from the coaches were overwhelmingly positive. The touch screen technology, specified assessment criteria, and graphical profiling helped to integrate assessment into the program along with increased awareness and understanding of the assessment process. The students’ subsequent reflections on the components of the coaching process positively impacted their performance. The study concludes that TST has the potential to assist in enhancing the learning process and bridging the gap between education and practice. Attention is drawn to the challenges of implementation.Cette étude de cas exploratoire évalue la mise en œuvre et l’utilisation, par les élèves entraîneurs, d’un système innovateur de profilage d’entraîneurs, la technologie des écrans tactiles (« TÉT »), pour évaluer les comportements des entraîneurs.

Published: January 2019

Lectins are defined as proteins or glycoproteins capable of specific and reversible binding to carbohydrates. Inside this group of proteins, the most well-studied lectins belong to the Leguminosae family, and inside this family, the Diocleinae subtribe includes the most characterized lectin Concanavalin A (ConA), as well as ConBr, the lectin from Canavalia brasiliensis, the subject of this review. Since 1979, several studies have been published in the literature regarding this lectin, from its isolation and characterization to its several biological activities. This year, 2019, will mark 40 years since researchers have begun to study ConBr and 100 years since the discovery of ConA, making 2019 a momentous year for lectinology. Owing to the abundance of studies involving ConBr, this review will focus on ConBr’s purification, physicochemical properties, functional and structural analyses, biological activities and biotechnological applications. This will give researchers a broad glimpse into the potential of this lectin, as well as it characteristics, as we look ahead to its expanding applications in glycomics and biotechnology.

Authors: Thakkar Vaishali , Pandey Ekta , Pandya Tosha , Shah Purvi , Patel Asha , Trivedi Roma , Gohel Mukesh , Baldaniya Lalji , Gandhi Tejal
Published: January 2019

Background:

Targeting anti-tubercular therapeutics to alveolar macrophages
using microparticles technology mainly focuses on increasing local concentrations of
therapeutics and potentially reducing the frequency of dosing requirements. Rifampicin
(RIF), Ofloxacin (OFX) and Ethambutol (ETH) combination show synergism.

Objective:

In light of the above facts, the focus of the present study was to develop and
characterize novel Dry powder Inhaler formulation incorporating novel drug combination
as a pulmonary delivery for the effective eradication of Tuberculosis.

Method:

Biodegradable microparticles containing RIF, OFX and ETH were prepared by a
spray drying technique using PLGA polymer through the critical process as well as
polymer attributes were screened and optimized using 23 factorial design. The identified
critical process parameters (CPP’s) viz. Inlet temperature, Aspiration rate, and feed rate
were selected as independent variables while percentage yield, percentage entrapment
efficiency, and particle size were selected as a response. The formulated microparticles
were evaluated for particle size, drug-polymer compatibility study, aerodynamic
behavior, morphology, particle size distribution, crystallinity, residual solvent content,
in-vitro drug release study, and stability study.

Results:

By choosing the optimum spray drying conditions maximum yield of 73%, entrapment
efficiency of 86% and particle size of 1.4 μm was attained of the optimized
batch. Thus the results revealed that spherical microparticles are suitable for inhalation
and sustained release for 12 h.

Conclusion:

The successful formulation and evaluation of dry powder could be used as
an enhanced therapeutic alternative of the standard oral anti-tubercular regimen, rescuing
oral dosing, shortening drug regimen and limiting toxicity. This will ultimately improve
patient compliance and diminish the prevalence of MDR resistance.

Stadtliturgie im mittelalterlichen Utrecht in der Karwoche
Authors: Tongeren Louis van
Published: January 2019

Van de vele kerken die in de loop van de middeleeuwen in de stad Utrecht werden gebouwd hadden er vijf een bijzondere band met elkaar. Dat zijn de Salvator of Oudmunster en de kerken toegewijd aan Martinus (voorloper van de huidige Dom), Petrus, Johannes en Maria. De onderlinge band van deze kapittelkerken komt onder andere naar voren in vieringen van de liturgie gedurende het jaar door meer kapittels gezamenlijk. Deze gezamenlijke liturgie wordt beschouwd als een manifestatie van de onderlinge verbondenheid van de vijf kapittels en wordt wel aangeduid als stadsliturgie of stedelijke kapittelliturgie. Van drie van de vijf kerken is een liber ordinarius bewaard en van Oudmunster ook nog een kostersboek. Nauwkeurige bestudering van de organisatie en de vormgeving van de liturgie van de Goede Week in deze bronnen geeft inzicht in de eigenheid van de liturgische praktijk in de afzonderlijke kerken. Zo blijkt dat niet alle rituelen in alle vijf kerken gevierd werden en dat er verschillen waren in de uitvoering en vormgeving. En hoewel gedeelten van de liturgie weliswaar door meer kapittels gezamenlijk werden gevierd, komt uit de bronnen naar voren dat vooral de twee oudste kapittels van Dom en Oudmunster samen optrekken. Hun onderlinge historische band komt sterker naar voren dan de gezamenlijke band tussen de vijf kapittels.

Published: January 2019

Background

Community-based participatory research is an effective tool for improving health outcomes in minority communities. Few community-based participatory research studies have evaluated methods of optimizing smartphone apps for health technology-enabled interventions in African Americans.

Objective

This study aimed to utilize focus groups (FGs) for gathering qualitative data to inform the development of an app that promotes physical activity (PA) among African American women in Washington, DC.

Methods

We recruited a convenience sample of African American women (N=16, age range 51-74 years) from regions of Washington, DC metropolitan area with the highest burden of cardiovascular disease. Participants used an app created by the research team, which provided motivational messages through app push notifications and educational content to promote PA. Subsequently, participants engaged in semistructured FG interviews led by moderators who asked open-ended questions about participants’ experiences of using the app. FGs were audiorecorded and transcribed verbatim, with subsequent behavioral theory-driven thematic analysis. Key themes based on the Health Belief Model and emerging themes were identified from the transcripts. Three independent reviewers iteratively coded the transcripts until consensus was reached. Then, the final codebook was approved by a qualitative research expert.

Results

In this study, 10 main themes emerged. Participants emphasized the need to improve the app by optimizing automation, increasing relatability (eg, photos that reflect target demographic), increasing educational material (eg, health information), and connecting with community resources (eg, cooking classes and exercise groups).

Conclusions

Involving target users in the development of a culturally sensitive PA app is an essential step for creating an app that has a higher likelihood of acceptance and use in a technology-enabled intervention. This may decrease health disparities in cardiovascular diseases by more effectively increasing PA in a minority population.
Hoax in Modern Politics
Authors: Utami Pratiwi
Published: January 2019

The propagation of hoaxes on social media has contributed to political tension in many countries. The 2016 US presidential election provides evidence of how fake news can generate more social media engagement than real news. In multicultural Indonesia, the history of anti-communist, anti-Christian, and anti-Chinese pogroms increases the level of sensitivity and sentiment, especially when dealing with racial issues. This paper explores the role of hoaxes in Indonesia’s contemporary politics. It investigates the characteristics of hoax information circulated on social media during the 2017 Jakarta election using a memetic practice approach. This study perceives hoaxes as having acted like memes in terms of the ways in which they dismantle existing source material to tap into ideas or sentiments people connect with. Hoaxes as memes alter original items into new forms of artifacts, with new messages that resonate with existing beliefs in society. Consequently, hoaxes can create a culture based on a shared belief among the community and, in the era of increasing polarization, a hoax has the potential to be a means of political partisanship. However, with the tendency to overpower the truth and lead people away from believing facts, hoaxes can be a threat to participatory democracy.
DO EARNINGS MANAGEMENT ABLE TO REDUCE STICKINESS COST LEVELS?
Authors: Martania Rani Media , Eltivia Nurafni , Setiawan Mohamad Arief
Published: January 2019

The purpose of this research is to determine the occurence of stickiness cost in SG&A (Selling, General and Administration) cost and to see whether the stickiness cost degree can be derive through earning management. Multiple linear regression using regression model from Anderson et al. and Farzaneh et al. are carried out to analyze the data. The results of this research show that SG&A cost is sticky, because it increased by 0.908% at 1% increase in sales but decreased by 0.016% at 1% decrease in sales. It happens because the manager retain the unutilized resources when facing a decline in sales. Furthemore, the results of this research find that earning management can derive the degree of stickiness cost, even cause anti-sticky in SG&A cost. It happens because the manager who has an incentive to avoid reporting loses and earning decreases, try to reduce cost when sales decline by earning management.

MELANCOLIA. MELANCHOLY

Published: January 2019

Na medida em que um planeta chamado Melancolia se desloca em direçãoà Terra, a narrativa fílmica vai revela uma visão pessimista em relação a sociedade. Mas, meu olhar ao colidir com o olhar contundente da obra, desterrito rializa-se, deslocando o pessimismo e a melancolia que se apresentam como sintomas do mal-estar do nosso tempo, para inaugurar outras possibilidades de ver. Se, por um lado, o diretor - Lars Von Trier - expõe a densidade de sentimentos que traduzem as angústias da vida contemporânea, por outro, cuida de emoldurá-los com cenários e sons de infinita beleza, dando-me a certeza de que a Terra não é de todo má e a vida vale a pena. O filme nos convida a pensar a função da educação. Como preparar indivíduos para o enfrentamento da vulnerabilidade da condição humana? Penso que o no sso desafio hoje, é educar para a lucidez, evitando assim a arrogância de acharmos que a vida está dada como verdade pronta e acabada.

O texto será mobilizado por uma escrita rizomática, tecida em pequenos blocos, verbetes, trajetos ou pegadas, uma experimentação, que não pressupõe um início, meio ou fim. Cada bloco é uma entrada, uma abertura, um rizoma, sem ponto de partida, as entradas são múltiplas, mas como todo rizoma, as linhas da escrita se encontram, ressoa conexões, barulhos. O convite é para experimentar os blocos de escrita rizomática, extraindo deles o que há de mais potente para pensar a educação, para então voltar ao caminho, pois uma escrita rizomática está sempre em trânsito, movimento.

Transplantation of hematopoietic stem cells: historical aspects
Authors: Khomenko V.
Published: January 2019

The historical review covers more than 60 years of the development of hematopoietic stem cells transplantation (HSCT) in the world: from animal experiments and first bone marrow transplantations to incurable patients to the widespread use of HSCT as an effective treatment for a number of hematological, oncological and other diseases. During this period on the way of its development, a number of scientific, technical and applied problems have been overcome. The author focuses on the achievements in many related fields of medicine and biology (hematology, oncology, immunogenetics, pharmacology, radiotherapy, transfusiology, cryobiology, etc.), which have changed the role of HSCT from the “therapy of despair” at the terminal stages of the disease to the priority therapeutic strategy for the treatment of a number of cancer and non-malignant diseases in the early stages of the disease. The study of historical experience will be useful for Ukraine, which relatively recently has begun to introduce the method of HSCT into clinical practice.
The effects of the transplantation of thymus-derived multipotent stromal cells on the immune system and survival of lethally irradiated mice
Authors: Nikolska K.
Published: January 2019

The traditional source for regeneration of the immune system is hematopoietic stem cells. Multipotent stromal cells (MSCs), especially MSCs of the thymus, have been significantly less studied for this purpose.The aim was to study the regenerative, immunobiological and radioprotective properties of thymus-derived multipotent stromal cells.Materials and methods. Researches were conducted to study the effect of transplantation of thymus-derived MSCs on the survival and features of restoration of the immune system of lethally irradiated mice. Lethally irradiated (with dose 9 Gy) CBA mice, 5-6 weeks old, were injected intravenously with 5·104 thymus-derived MSCs. On the 30th day the cellularity of lymphoid organs, bone marrow and blood, natural and adaptive immunity were studied.Results. It was found that transplanted thymus-derived MSCs significantly prolonged the survival and average lifespan of mice, restored the cellularity of bone marrow, the ability of bone marrow stromal cells to form fibroblast colonies, greatly increased the cellularity of the thymus and contributed to the normalization of the number of leukocytes in the blood. In addition, the natural cytotoxic activity of splenocytes and their ability to synthesize α/β- and γ-interferons, significantly increased, the number of antibody-producing cells was stimulated and the synthesis of antibodies increased. The concentration of the tumor necrosis factor α in the blood was significantly reduced.Conclusions. The results indicate that thymus-derived MSCs possess pronounced regenerative and immunobiological activity, which provides these cells with radioprotective ability. The obtained data can be used to develop combined cell transplants and new methods for improving their regenerative potential and radioprotective effects.

Published: January 2019

Time course of adsorption of the different pollutants from water is the basis
in the testing of an adsorbent. Over the years, several kinetics models have
been proposed. Nevertheless, pseudo-first-order and pseudo-second-order
kinetic models are by far the most used in the testing. Since various
biological materials have complex composition, it is assumed that the
adsorption kinetics on such materials, named biosorbents, can not be
described sufficiently well by these two models. In this paper, both
generalized and preset order kinetic equations were applied on the results
of copper and chromium ions adsorption onto spent brewer?s grain. The
biosorption of copper ions corresponds the best to the 2.5, and biosorption
of chromium ions to the 4.9 reaction order. The analyses of the kinetic
tests results on different biosorbents conducted by other authors indicate
that the determination of the reaction order should be obtained by
generalized kinetic model. It was also established that the f value
(relative goodness of curve fitting) was better for the prediction which
equations is better, than the R value (correlation coefficient).

Published: January 2019

The modified Washburn equation and the lipophilic/hydrophilic (L/H) ratio are
most commonly used for the wettability characterization of fibers.
Therefore, this liquid penetration method was applied for the wettability
investigation of stainless steel fibers with mineral oils and the
lipophilic/hydrophilic (L/H) ratio was obtained. As test liquids mineral
oils and water were used. It was found that the range of L/H ratio values
was vastly broad (from 1048340 to 37802) concluding that this liquid
penetration method was not suitable for these particular fibers.
Consequently, in this study a modified method was developed defining a novel
route to filter media wettability characterization and establishing the
lipophilic/lyophobic ratio (LLR). As the new reference liquid the medical,
white oil was selected. By using polar mineral oils the interval of the LLR
ratio for stainless steel fibers ranged from 1 to 28. It can be concluded
that the suggested LLR ratio, was adequately selected as a measure of
wettability for stainless steel fibers with mineral oils. The LLR ratio
exponentially increased with the increase of the neutralization number and
viscosity of investigated mineral oils.

Published: January 2019

The objective of this study was to evaluate the possibility of application of
two triticale varieties, NS Paun and Odisej, as partial substitutes for
barley malt in wort production, based on the triticale analyses,
micromalting, and analyses of the produced triticale malts, with a highlight
on the activity of amylases during the malting process. The analyses of two
triticale varieties showed higher extract content and diastatic power in
comparison to barley malt. In the varieties NS Paun and Odisej, the extract
was by 11.4% and 6.3% higher than the standard values for barley malt,
respectively. Diastatic power in varieties NS Paun and Odisej was by 100% and
111.9% higher than in barley malt, respectively. In both varieties, ?- and
?-amylases activities were also high. The ?-amylase activity increased
during the micromalting 34 and 20 times, respectively, in comparison to
native triticale grain. The ?-amylase activity also increased during
micromalting, but to a lesser extent. The produced triticale malts had good
technological parameters and could be used as a partial substitute for barley
malt in wort production.

Published: January 2019

The negative influence of the environmental pollutants on building materials
used for fa?ades could be minimized by applying protective photocatalytic
coatings with selfcleaning properties. Novel inorganic-inorganic
nanocomposite photocatalytic coating based on TiO2/Zn-Al layered double
hydroxides (LDHs) was applied on commercial fa?ade paint and the functional
properties (photocatalytic activity and surface properties) were studied
before and after durability tests towards the adhesion of the coating. The
results showed that the TiO2/ZnAl LDH based coating did not influence
esthetic appearance, surface roughness and microhardness of the fa?ade
paints. The coating demonstrated a significant photocatalytic activity and
the photo-induced hydrophilicity, enabling the self-cleaning effect. The
study of the influence of temperature and relative humidity on
photocatalytic activity indicated that optimal weather conditions for the
application of coating precursors onto the fa?ade paints are in the spring
and in autumn seasons.

Instrumental neutron activation analysis is used to determine a content of 47
elements (Na, Mg, Al, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni, Co, Cu, Zn, As,
Se, Br, Rb, Sr, Zr, Mo, Ag, Cd, Sb, I, Ba, Cs, La, Ce, Nd, Sm, Eu, Gd, Tb,
Dy, Tm, Yb, Lu, Hf, Ta, W, Au, Hg, Th, and U) in mosses (Homolothecium sp.,
Hypnum cupressiforme Hedw., and Brachythecium mildeanum (Schimp.) Schimp.)
and lichen (Cladonia fimbriata (L.) Fr.) collected in three locations in
Eastern Serbia over years 2006-2010. Concentrations of six elements (Zr, Nd,
Gd, Tm, Yb, and Lu) in mosses in Serbia are measured for the first time. For
other elements, the obtained concentrations fall within the ranges reported
for mosses and lichens in Europe, but no declining trend in concentrations of
V, Cd, Cr, Zn, Ni, Fe, and Cu, that has been described in the literature, can
be inferred from our results. Factor analysis shows that terrigenous and
industrial components are the highest contributing factors to the elemental
composition and that the most polluted measurement site is in the vicinity of
a copper mining and smelting complex.
Rolling Resistance Revisited
Authors: Li Yi , West Robert L.
Published: January 2019

Rolling resistance defined as energy loss per unit distance is well accepted by the tire science community. It is commonly believed that the dominant part of energy loss into heat is caused by the viscoelasticity of rubber compounds for a free-rolling tire. To calculate the rolling loss (hysteretic loss) into heat, a method based on tire forces and moments has been developed to ease required measurements in a lab or field. This paper points out that, by this method, the obtained energy loss is not entirely converted into heat because a portion of the consumed power is used to compensate mechanical work. Moreover, that part of power cannot be separated out by tire forces and moments–based experimental methods. The researchers and engineers have mistakenly ignored this point for a long time. The finding was demonstrated by a comparative analysis of a rigid, pure elastic, and viscoelastic rolling body. This research mathematically proved that rolling loss into heat is not resolvable in terms of tire forces and moments with their associated velocities. The finite element model of a free-rolling tire was further exercised to justify the concept. These findings prompt revisiting rolling resistance in a new way from the energy perspective. Moreover, an extended definition of rolling resistance is proposed and backward compatible with its traditional definition as a resistive force.

Psychomotor skills are the organized patterns of muscular activities guided by signals from the environment. These skills can be influenced by factors like age, gender, built of an individual and handedness. It’s a known fact that the dominant hand has more dexterity; nevertheless, proficiency of the non-dominant hand can be improved with repetition of tasks and procedures. The aim of the present study was to examine the influence of biofeedback mechanism on psychomotor skills performance and gender variation in their activity. Eighty participants aged between 20-30 years were recruited after taking the informed consent. All the subjects performed number countdown test and 100 pin dexterity test. Tests were done by fixing the subject’s heart beats instead of stipulated time which was picked up by finger Pulse plethysmography using optocoupler principle. The results were compared between the males and age-matched female participants. The pin dexterity scores with a right and left hands in males (57.2±8.1, 42.16±7.3) were significantly higher than females (48.41±8.4, 37.58±6.8) (p = 0.001 and p = 0.01). There was no significant difference in number countdown test scores. The results suggest that males handle a skilled performance better than females. This is perhaps males were less anxious as the task was designed in such way that it has to be completed by counting down the heart beats. In that way, the males got more time duration as the heart rate did not shoot up when the task was assigned.

Penggunaan softlens atau lensa kontak yang menjadi penunjang daya tarik atau penampilan seseorang telah menjadi trending atau gaya hidup dalam kecantikan dikalangan masyarakat. Awalnya, softlens digunakan hanya untuk orang -  orang yang menderita kurang penglihatan. Softlen memiliki fungsi yang sama dengan kacamata namun lensa kontak memiliki tampilan yang tak tampak dan lebih ringan digunakan oleh konsumen karena langsung dipasang pada kornea mata. Selain itu, lensa kontak yang memiliki banyak warna dan model ini menarik perhatian konsumen untuk lebih banyak mencoba mana yang terlihat bagus dimatanya. Untuk itu, menentukan warna dan model yang cocok konsumen harus mencoba tester softlen tersebut. Mencoba tester yang tidak diketahui steril dan aman untuk digunakan cukup berbahaya bagi kesehatan mata konsumen. Menurut pendapat salah satu dokter spesialis mata di RSUD dr Soetomo terdapat 50% pasien yang mengalami gangguan mata karena lensa kontak yang terkontaminasi oleh amoeba sedangkan 1% persen dari pasien mengalami gangguan berat yang menyebabkan kebutaan permanen. Dari masalah inilah saya mendapatkan ide untuk membuat system tester softlens di Optik. Metode penelitian yang digunakan yaitu metode eksperimen dan metode pengembangan software yang digunakan yaitu metode waterfall. Di dalam aplikasi tester softlens ini memiliki tujuan untuk konsumen dapat mencoba tester softlens tanpa mencoba langsung di mata dan menghemat biaya untuk tester.
