Published: March 2022

Background and Aim: Indigenous Kedah-Kelantan (KK) cattle are well adapted with distinguished reproductive capabilities; they account for more than 70% of the domestic beef production in Malaysia. The published literature on the phenotypic and morphometric characteristics of KK cattle are sparse and require further improvement. Therefore, this study was aimed to determine the phenotypic and morphometric characteristics of Malaysian KK cattle and method of estimating live body weight (BW). Materials and Methods: Morphometric and phenotypic measurements were taken from 184 KK cattle (102 males and 82 females) sourced from three regions. Each animal's color pattern was recorded for their coat, muzzle, face, eyelashes, horns, tail switch, hoof, and legs through visual observation. Length measurements were taken of the body, face, ear, horn, tail, and rump. Several morphological features such as length, width, and girth were measured using a measuring tape, while wither height and hip height were assessed with a measuring scale. Results: Brown is the predominant coat color in KK cattle (>82%). The overall means of head length, face width (FW), ear length, horn length, wither height, heart girth (HG), body length (BL), and rump length were 42.5±4.5, 17.3±2.9, 19.8±3.1, 9.9±4.4, 104.3±7.1, 127.4±13.2, 98.3±12.3, and 32.4±4.1 cm, respectively. Different morphometric parameters of length, width, and circumference were significantly (p<0.01) larger in males than females, except for tail length and TG. Correlation coefficient and multiple regression analysis clearly revealed that BL is the best parameter for estimating live BW in KK cattle. Conclusion: Phenotypic and morphometric measurements in this study showed that Malaysian KK cattle generally possess a brown coat pattern with smaller body size, while BL revealed to be the best parameter to predict BW. The data generated from this study would be useful as baseline data for the identification and selection of KK cattle based on their phenotypical- and morphological-features for further improvement of this breed.

Background and Aim: Several Ecuadorian farms use human test strips (cheaper than veterinary strips) to diagnose bovine ketosis; however, their reliability is unknown. This study aimed to determine the confidence level of human strips for the detection of ketosis in bovines by comparing two diagnostic methods for ketosis: one used in bovines (gold standard) to analyze blood samples and the other used in humans to analyze urine samples. Materials and Methods: The study was conducted on an Ecuadorian farm using 50 animals, ten from each of five categories: heifers, 4 months pregnant (4MP), 15 days prepartum (15DPRE), 15 days postpartum (15DPOST), and 42 days postpartum (42DPOST). Blood samples were collected through coccygeal venipuncture and urine samples were collected during spontaneous urination. BHBCheck™ assay was used to measure β-hydroxybutyrate (BHB) in the blood, whereas Combur10Test® was used to measure acetoacetate (AcAc) in urine for the determination of ketosis. Results: BHB was detected in all animals. Based on a ketosis cutoff point of 0.8-1.2 mmol/L, 13 animals from the 15DPOST and 42DPOST categories had ketosis; AcAc was detected in the urine from nine animals originated from the two same categories. Metabolites, either BHB or AcAc, were not detected in heifers, 4MP, or 15DPRE individuals. Finally, the BHBCheck™ assay had better efficiency in detecting ketosis in animals (p<0.05) than the Combur10Test®. Conclusion: Combur10Test® urine strips reached 92% reliability for the detection of ketosis in dairy cattle, compared to BHBCheck™ assays.

Introduction Genomic mutations in TP53 gene in association with etiological risk factors have been associated with oral carcinogenesis. Herein, we screened for genomic variants of TP53 predisposing to oral cancers in Senegalese patients. Methodology 88 patients with confirmed diagnostic were recruited after informed consent. Blood samples were collected from each patient to perform DNA extraction, PCR amplification of all coding exons of TP53 followed by Sanger Sequencing of PCR products. Nucleotide sequences were analysed with Genalys software. 94 blood donors with no cancer diagnosis were also recruited as controls for association study between the most common variants identified in patients and predisposition to oral cancers. Results Sequence analysis showed that 52.27% of patients carry at least one mutation in TP53. Eleven genomic variants were identified, 7 variants already reported in databases and 4 new variants. The most recurrent variants in this study already reported as cancer-related variants were Pro72Arg (rs1042522; Arginine frequency estimated at 31.26%) and a 16 bp insertion in intron 3 (rs59758982; allelic frequency estimated at 26.25%). Haplotype analysis between these variants showed a strong linkage disequilibrium (D’ = 0.999, r2 = 0.153 and p-value < 0.05). However, association study did not find any significant association with susceptibility to oral cancer (p-value > 0.05). Conclusion Our study highlighted that despite the absence of association between the two most common cancer-related variants in Senegalese patients diagnosed with oral cancer, their strong LD suggested that they could be transmitted together in a common haplotype which may be implicated in oral carcinogenesis.

Selection of Loads in the Design and Optimization of Manipulators of Portable Mobile Robots for Special Applications
Authors: Krakówka Tomasz , Typiak Andrzej
Published: March 2022

The construction of mobile robot manipulators for special applications must be optimized to achieve the required working capacity while maintaining a low mass. In the literature on the optimization of manipulator structures, the authors most often take into account the most unfavorable load case in their calculations or take into account several distinguished load cases resulting from the static or dynamic of the loaded manipulator. To optimize the design of a teleoperated robot manipulator, which during operation is exposed to contact with obstacles in an unstructured environment, the load analysis must be carried out in many aspects. The results of such analysis are used to select manipulator elements, e.g. drives, and to determine the loads for the design of the load-bearing structure and its optimization. The determined loads can be used to perform topological optimization of components of manipulators to minimize the mass while maintaining strength adapted to the operating conditions. Preliminary work on the preparation of a method for selecting such loads is presented.

Published: March 2022

Human behaviour change is necessary to meet targets set by the Paris Agreement to mitigate climate change. Restrictions and regulations put in place globally to mitigate the spread of COVID-19 during 2020 have had a substantial impact on everyday life, including many carbon-intensive behaviours such as transportation. Changes to transportation behaviour may reduce carbon emissions. Behaviour change theory can offer perspective on the drivers and influences of behaviour and shape recommendations for how policy-makers can capitalise on any observed behaviour changes that may mitigate climate change. For this commentary, we aimed to describe changes in data relating to transportation behaviours concerning working from home during the COVID-19 pandemic across the Netherlands, Sweden and the UK. We display these identified changes in a concept map, suggesting links between the changes in behaviour and levels of carbon emissions. We consider these changes in relation to a comprehensive and easy to understand model of behaviour, the Opportunity, Motivation Behaviour (COM-B) model, to understand the capabilities, opportunities and behaviours related to the observed behaviour changes and potential policy to mitigate climate change. There is now an opportunity for policy-makers to increase the likelihood of maintaining pro-environmental behaviour changes by providing opportunities, improving capabilities and maintaining motivation for these behaviours.
Achieving a healthy indoor environment by using an emissions barrier to stop the spread of chemicals from a building into the indoor air
Authors: Larsson Lennart , Mattsson Johan
Published: March 2022

An emissions barrier was used in a premises due to complaints about the indoor air quality (IAQ) as a result of emissions from the building in question. The emissions comprised chlorophenols/chloroanisoles and polycyclic aromatic hydrocarbons (PAH) from treated wood and volatile organic compounds (VOCs), mainly 2-ethylhexanol, from polyvinyl chloride (PVC) flooring and the glue used to paste the flooring onto a concrete slab. Attaching the barrier at the surfaces from where the emissions were spread (floor, walls, ceilings) resulted in a fresh and odour-free indoor air. We conclude that using an emissions barrier in buildings made unhealthy by moisture is an efficient way of restoring pleasant and healthy indoor air.

Introducción: la obesidad es un problema de salud mundial que ha sido vinculada con la posición social de las personas. Si bien la evidencia que relaciona estas variables es clara, se ha puesto menos atención a los mecanismos por medio de los cuales estas variables pueden asociarse. El objetivo de este estudio fue determinar si la posición social se relacionaba directamente con obesidad abdominal e indirectamente vía percepción de discriminación, afectividad negativa y calidad de la dieta, y el rol moderador del apoyo social. Método: 420 funcionarios de una universidad chilena. Se midió el perímetro de cintura como proxy de obesidad,se utilizaron instrumentos de autorreporte para variables psicológicas y conductuales. Resultados: análisis de ecuaciones estructurales revelaron que la posición social no se asoció directamente con obesidad abdominal, pero sí a través de una secuencia de mediación que incluyó la percepción de discriminación, afectividad negativa y calidad de la dieta. El apoyo social no moderó estas relaciones. Conclusión: se identifican mecanismos que median el nexo entre posición social y obesidad abdominal. Se destaca la relevancia de considerar variables psicológicas y conductuales subyacentes en esta relación.
The Midbrain: Central Gray Matter is the Resonance Center of the Radionics System
Authors: Fujii Takanori
Published: March 2022

Radionics was developed by Albert Abrams, an American physician, as a diagnostic and treatment tool based on the percussion auscultation method. Although the efficacy of radionics for the treatment of diseases has been reported, there is a lack of theoretical evidence for its effects. The inputs and outputs of radionic devices are clearly defined; however, limited information is currently available for the location at which they interact. Based on an examination of the unconscious signal-sensing functions of the brain as an alternative to psychochemical methods, the present study provides novel insights that will contribute to a theoretical explanation of radionics. The present study identified the central gray matter of the midbrain as the central site of action of radionic devices.

This study considers the partial substitution of calcium with zinc in the superconducting compound Hg0.9Ag0.1Ba2 Ca2-x ZnxCu3 O (8+δ). Different samples of this compound had x equal to 0.05, 0.1, or 0.15. Preparation of the samples was done using the solid-state reaction method. This included sintering at a temperature of 850°C for 24 hours. Through the use of X-ray powder diffraction, the structural elements of the samples were then analyzed. The XRD analyses revealed them to be tetragonally structured polycrystalline with high Tc phasing (Hg-1223). The change in zinc concentration produced a change in the samples’ lattices’ structural parameters (a, b and c-axis. c/a), their density of mass (ρm), and their volume fractions (V-ph). The four-probe technique tested the electrical resistivity of the samples to define the critical temperature for the occurrence of zero resistivity Tc (offset). The optimum Tc (offset) was ascertained to be at 140K for the Hg0.9Ag0.1Ba2 Ca1.85 Zn0.15Cu3 O (8+δ) sample.

Published: March 2022

The laser dyes can be used in many practical systems as a gain medium. The dye consists of fluorescence molecules in organic or water solvent. A dye can be pumped efficiently and can exhibit high gain, due to the high fluorescence quantum efficiency and broad emission and absorption cross-sections. For this reason, the dye used as a gain medium. The large bandwidth of the gain in the dyes gives a broad tuning range for the laser's output. It (RhB dye) was utilized at various concentrations, and a UV-VIS spectrometer was used to study the absorption spectra of these materials, followed by fluorescence spectroscopy to investigate the emission spectrum. A greater concentration of dye (1*10-5M) was used to mix with different amounts of Ag NWs. It will have a substantial influence on the parameters of the emission and absorption spectra. It was discovered that the emission parameters (emission intensity, lasing threshold) are greatly dependent on the concentration of Ag NWs.

The study is based on the Parkes Galactic All Sky Survey (GASS III) to investigate the neutral hydrogen (H I) emission in the areas surrounding the disc of the Milky Way (MW). The aim of the study is to looking for a sign of disk-halo interaction by tracing the kinematics of the H I in different heights from the midplane of the MW, as a spiral galaxy. The analysis focused on the 21 cm spectral line to examine the shape of the emission line and determine the Gaussian parameters according to the number of fitting functions. Twelve positions were investigated by chosen two slices with longitude (l = 20̊, 340̊) and different latitude (b = 10̊, 12̊, 14̊, 16̊, 18̊, 20̊) for each slice. In some positions the line profiles show broadening or even line splitting as a result to interaction between different component with different kinematics and physical environments. Our results also indicate that the velocity reduces with increase the height from the midplane and take this as evidence of lags as a result to the interaction between the disk and halo.

The Quantum Hologram Theory of Consciousness as a Framework for Altered States of Consciousness Research
Authors: Valverde Raul , Korotkov Konstantin , Swanson Chet
Published: March 2022

We can learn more about how our reality is made and what non-ordinary states of consciousness are by studying the Quantum Hologram Theory of Physics and Consciousness (QHTC). The QHTC says that consciousness is not local and that altered states of consciousness can help us understand how our minds work in more than one way. That's what Schrödinger thought. He thought that the quantum mechanical wave function was a field of consciousness. QHTC is based on holographic theories for human consciousness. These theories say that the brain works like a hologram and that it processes images into interference patterns that are then turned into virtual images, just like a laser hologram. These quantum waves can store a lot of information, which our brains use to make our three-dimensional world. This article says that this last theory should be the main framework for research on altered states of consciousness, and it talks about how to get data for analysis and how to get into an altered state for possible experiments.

Authors: Hu Wenjun , Guo Xing , Du Yifeng
Published: March 2022

Cerebral white matter lesion (WML) and lacunar infarction (LI) were primary causes of cognitive deficit. Our study aimed to investigate the correlation between LI and cognitive deficit in the elderly with WML. A total of 118 participants (96 WML patients and 22 controls) were consecutively enrolled according to neuroimaging diagnosis of magnetic resonance imaging for this retrospective study. Neuroimaging evaluation and cognitive function assessment were analyzed. Compared with the controls, moderate and severe WML groups had significantly lower scores of Mini-mental State Examination (MMSE) and Montreal Cognitive Assessment (MOCA). Most cognitive domains of MOCA scores decreased, corresponding to the severity of WMLs. While there was no significant difference in score of MMSE between deep WML (DWML) and periventricular WML (PVL) groups, the scores of visuospatial/executive and naming function domains of MOCA appeared to be low in the DWML group. The scores of MMSE and MOCA were higher in only WMLs (WML−) group than WMLs combined with LIs (WML+) group, except for the naming cognitive domain. Moreover, LIs were independently correlated with the cognitive deficit in the elderly with WMLs. In the elderly with WMLs, the presence of LIs is associated with further aggravation of cognitive deficit.

The aim of the study was to investigate the inhibitory effect of hydroxysaff yellow A (HSYA) on diabetic retinopathy (DR). For this, a total of 27 rats were randomly divided into normal control, model, and HSYA groups. The body weight, blood glucose, and blood–retinal barrier damage of the rats were observed and compared. The pathological change of retinal tissue were measured using H&E staining. The apoptosis of retinal tissue ganglion cells was detected by TUNEL. The interleukin (IL)-1β and tumor necrosis fator (TNF)-α levels were detected using enzyme-linked immunosorbent assay. The level of malondialdehyde (MDA) was detected using thiobarbituric acid method. Superoxide dismutase levels were detected using xanthine oxidase method; Nrf2 and total HO-1 protein expressions were detected using western blot assay; Bcl-2 and P53 protein expression was measured using immunohistochemical staining. The body weight and retinal damage of the HYSA group were significantly improved (p< 0.01, respectively). The apoptosis index of the HYSA group was lower than the model group (p< 0.001). The IL-1β, TNF-α, and MDA levels of the HYSA group were significantly improved in comparison with those of the model group (p< 0.01, respectively). The Nrf-2, HO-1, Bcl-2, and P53 protein expression of HYSA group was significantly improved (p< 0.001, respectively). In conclusion, HYSA can effectively alleviate the apoptosis of retinal ganglion cells in type 2 diabetic rats and improve the progression of DR.

U-bending is increasingly used in the sheet metal industry such as car door pillars. However, springback phenomenon always tends to occur after removing sheet metal from the fixtures and resulting in changing product effectiveness, wasting material as well as increasing manufacturing costs. Thus, minimizing springback in the bending of sheet metal is vital to maintain close geometric tolerances in the deformed part. Many researchers have done investigated and predicted the springback occurrence by experiments and simulations. Neverthessly,  there is no actual study on the die shoulder patterning method (DSPM) to reduce springback of hat-shaped parts. In this paper, the hat-shaped part is deformed using the new developed forming method and have been experimented with as well as validated using three-way Anova and graphical analysis. As expected, DSPM dominates the springback sensitivity, with higher contact area reducing the springback of hat-shaped parts. For AISI 1030 of pattern 2, springback is dramatically reduced as the sliding stress between the die shoulder and surface of the blank is optimized.

Published: March 2022

Thin-walled parts are commonly used in the aerospace sector. However, there are serious machining challenges, such as deflection, deformation and vibration. The final thin-walled component machining will deteriorate the dimensional accuracy and surface quality. This is due to the vibration and deformation that occurs during flexible milling of thin-walled structures since the workpiece rigidity is lower than the cutting forces of the milling cutter. The gradual reduction of the thin-wall thickness during the end milling process results in significant deflections and deformations due to its low rigidity and low stiffness. In recent years, different approaches have been used to deal with these challenges. This paper presents a new technique for machining thin-walled parts with great accuracy, excellent flatness and straightness properties, and good productivity. The authors have developed a new milling technique using simultaneous double-sided cutter milling, in which synchronized vertical double end milling cutter finishes and machines both thin-wall surfaces simultaneously. This produces lower cutting thrust forces on the walls, as each cutting thrust force cancels out the other. The rotation of the milling machine spindle is transmitted to the double cutters by an in-house double-axis adapter. Surface errors are minimized, flatness and straightness properties are significantly improved, and the thin-wall deflection can be neglected, as shown in our results. The thin wall can be finished in only one pass, and a 50% reduction in machining time can be achieved. In addition, thin-wall ﬂatness is improved about two to three times, compared to the conventional milling procedure.

Ethanol flex-fuel vehicles are introduced to Thailand’s market and believed that they provide an alternative way in terms of reducing crude oil and octane booster import. Many literatures suggested that they also helped to reduce some emission species including the greenhouse gas. However, sufficient proof of this flex-fuel vehicle comparing the conventional versus realistic driving cycle tests during cold starts is not clearly identified. This research focuses on the comparison of performance, fuel consumption, and emissions of a flex-fuel vehicle using Gasohol E10, E50, and E85 tested under the New European Driving Cycle (NEDC) and Bangkok Driving Cycle (BDC). Tests were done on a Chassis Dynamometer in the Automotive Emission Laboratory of the Pollution Control Department. Considering emission data from both test cycles, the more ethanol ratios in gasoline, the more CO, NMHC, NOx, CO2 and PN emissions reductions. On the contrary, HC emissions are increased but still under EURO4 standards. Fuel consumptions on E85 are increased around 30% compared to E10 for both test cycles. However, the pattern of driving cycles significantly impacts the amounts of CO/NOx emissions and fuel consumption.  During cold start periods, regardless of percentages of ethanol blends, the amounts of HC and CO emissions for both test cycles are similar due to running engine in rich conditions by ECU management to warm three-way catalyst. On the contrary, NOx emissions are strongly related to frequent acceleration and deceleration sequences of the tested driving cycle.

Bu çalışmanın amacı Türkiye’de henüz uygulaması bulunmayan Güney Kore ve İngiltere’de faaliyet gösteren öncü saf internet bankalarının oran analizi yöntemiyle finansal performanslarını ölçmektir. Önümüzdeki dönemde Türkiye’de de saf internet bankalarının faaliyet göstermesi kuvvetle muhtemeldir. Bu çalışmanın hem düzenleyici kurumlara hem de bu iş modelini tercih eden bankalara ışık tutması hedeflenmektedir. Güney Kore bankaları Kakao Bank ve K Bank 2018-2020 yıllık malî verileri FSS (Financial Supervisory Service)  Financial Statistics Information System ‘inden,  İngiltere’nin bankaları Atom Bank ve Monzo Bank’ın 2018-2020 arası yıllık malî verileri ise ilgili bankaların yıllık finansal raporlarından alınmıştır. Kakao Bank, kârlılık, gelir/gider dengesi ve ölçek ekonomisinden faydalanma açılarından konumuz diğer saf internet bankalarına örnek bir modeldir.  Kakao Bank faaliyete geçtikten iki yıl sonra ölçek ekonomisinden yararlanarak kâra geçmeyi başarmıştır. K Bank, Atom Bank ve Monzo Bank’ın faaliyet giderlerinin yüksekliği ve yeterli aktif büyüklüğüne erişememiş olmalar yaşadıkları temel zorluklar olarak görülmektedir. Diğer bir deyişle faaliyet giderlerini karşılayacak faaliyet geliri yaratamamaktadırlar. Bu bankalar aktiflerini kârlı bir şekilde büyüttüğü ve faaliyet giderlerini düşürdüğü ölçüde hedeflediği kârlılığa erişebilecektir. Monzo Bank’ın net faiz dışı gelirlerini arttırma yöntemleri ise diğer saf internet bankalarına örnek olabilecek kadar başarılı bulunmuştur.

Nomofobi, modern zaman bağımlılığı olarak ifade edilebilmektedir. Kavramın en önemli psikolojik etkenleri, cinsiyet ve sosyoekonomik durumun yanı sıra kişilik, duygusal zekâ, sosyal beceriler, uyum yetenekleri, benlik saygısı, sigara, alkol ve uyuşturucu tüketimi, eşlik eden diğer psikopatolojilerdir (Bragazzi ve Del Puente, 2014). Düşük duygusal zekâya sahip bireylerin bağımlılık türlerine yatkınlığını ortaya koyan çalışmalardan hareketle, yine farklı bir bağımlılık türüne atıfta bulunan nomofobi yaşama olasılıklarının da yüksek olduğu değerlendirilmektedir. Söz konusu noktadan hareketle, bu çalışma, üniversite öğrencilerinde duygusal zekâ ve nomofobi düzeyi arasındaki ilişkiyi incelemek üzere gerçekleştirilmiştir. Bu doğrultuda, Ankara’da bulunan üniversitelerde eğitim gören 258 öğrenciden anket yoluyla elde edilen veriler analiz edilmiştir. Çalışmada her bir değişkene ait doğrulayıcı faktör analizi (DFA) AMOS programı ile yapılmıştır. Değişkenler arası ilişkileri ortaya koymak için korelasyon analizi, hipotezlerin test edilmesi maksadıyla hiyerarşik regresyon analizi yapılmıştır. Bulgulara göre, üniversite öğrencilerinin duygusal zekâ düzeyi nomofobi üzerinde önemli etkilere sahiptir. Bu bağlamda, duygusal zekanın nomofobi ile negatif ilişkili olduğu sonucuna varılmıştır. Elde edilen bulgular ışığında, üniversite öğrencileri ve eğitim sektörü yöneticilerine de konu ile ilgili önerilerde bulunulmuştur.

Authors: Özçelik Oğuzhan
Published: March 2022

Bu çalışmada piyasalardaki belirsizlik, korku ve kur oynaklığının Türkiye’nin dış ticarette ödeme şekli tercihlerine etkileri 2002:Q1-2021:Q1 dönemi için analiz edilmiştir. Serilerin durağanlığı Hepsag (2021a) yumuşak yapısal kırılmalı doğrusal olmayan ESTAR birim kök testiyle, koentegre olma durumları; Hepsağ (2021b) doğrusal olmayan yumuşak geçişli asimetrik ESTAR koentegrasyon testiyle incelenmiştir. Analiz sonuçlarına göre; belirsizlikler uzun dönemli ihracatta vesaik mukabili ve mal mukabili ödemenin, ithalatta akreditifli ödemenin daha az tercih edilmesine neden olmaktadır. Korku düzeyindeki artışlar uzun dönemde Türk firmalarının peşin ve akreditifli ihracatı daha çok tercih etmesine ve mal mukabili ihracattan kaçınmasına neden olmaktadır. Döviz kurundaki oynaklık; Türkiye’nin ithalatta peşin ödeme yapmasını azaltmıştır.
