Published: September 2021

Color and light are the main factors in the car manufacturing industry, with not much research, conducted on this topic, related to employee physical comfort. The factor affecting employee work comfort is the color factor and lighting time in their workplace environment. Color is the light, reflected by an object, then interpreted by the eye based on the light that hits the object. The value of the color wavelength in the spectrum of 380 nm to780 nm impacts worker performance. Good lighting will affect whether or not the room’s light conditions affect the illumination’s value. A good working room condition will affect the physical comfort of employees. Employee physical comfort has developed in many previous studies. However, research on the configuration of colors and lighting in the manufacturing industry’s work environment is still underdeveloped. This research aims to measure and determine the impact of color and lighting at specific color wavelengths on the illumination value and the employee’s physical comfort. It starts with studying the color, light, human comfort, then examines the effect on the manufacturing industry employees’ performance in the wiring installation assembly industry. Color and light settings are proven essential to get better human comfort. Green color with a wavelength of 490 nm to 570 can increase the highest illuminate average lux value of 12.43 %. Yellow can increase the heart rate by 4.85 %, while green can reduce Diastole by 2.95 % and Systole by 1.29 %. Pupillary size changes L by 23.17 % and R by 21.43 %. The effect of green color and lighting time can increase the value of illumination and decrease heart rate, blood pressure, and pupil size so that it impacts the physical comfort of employees.

The most commonly prescribed medication for autoimmune disorders is Azathioprine (AZA), which negatively affects renal function and tissue structure. The aim of this work was to measure the therapeutic impact of Zingiber officinale L. extract (ZOE) on improving the function and structure of AZA-induced renal damaged tissue.
Methods: 70 rats with a weight range of 200±10 g and an age of 95±5 days were chosen for this experimental study. The animals were grouped into seven groups of ten, with two groups receiving no treatment (control groups) and five groups receiving ZOE, AZA, “AZA + ZOE”, and normal saline. AZA was given intraperitoneally, and ZOE was given by gavage (i.e., nasogastric tube) for 21 days. Finally, urea, uric acid, creatinine parameters, and the diameter of some key or important parts of the kidney were measured in different animal groups.
Results: it was found that the use of AZA (50 mg/kg) increased serum urea and creatinine concentrations, blood uric acid in comparison to the group of control (P<0.05). Whereas injecting ZOE (200 mg/kg) induces a considerable decrease in the concentration of the compounds mentioned above as compared to control animals and animals given AZA (P<0.05). Furthermore, the findings revealed that AZA caused inflammation and kidney tissue destruction, while ZOE improved, restored, and recovered the affected kidney tissue.
Conclusion: according to the research findings, it can be decided that ZOE has a protective and therapeutic impact on kidney tissue owing to its strong antioxidant attributes and its ability to inhibit free radicals produced by azathioprine
Study of the influence of the increased carbon content in electrodes on structure and properties of the welding seam during welding of 110G13 steel
Authors: Pashynskyi Volodymyr , Boyko Igor 
Published: September 2021

The object of research is the effect of the carbon-forming component of coated electrodes for welding and surfacing of Gadfield steel (110G13L and analogs) on the structure and properties of the weld.
One of the most problematic areas in the welding and surfacing of high-carbon steel is the high irregularity of the rod and coating melting rates. Therefore, the non-melted part of the coating is literally poured into the weld pool, which leads to significant chemical and structural inhomogeneity of the welded metal. The main hypothesis of the study is the assumption that it is possible to increase the homogeneity of the deposited metal by changing the conditions for the transition of carbon from the electrode to the weld pool by using an electrode rod made of carbon steel.
In the course of the study, electrode rods with different carbon contents were used. With an increase in the carbon content in the composition of the electrode rod, the fluidity of the drops increased, which contributed to a decrease in the strength of the welding current without harm to the welding and technological characteristics. This allows to reduce the generation of heat in the base metal, that is an effective measure to prevent hot cracks in the weld metal and heat affected zone
Studies of the composition of the electrode metal droplets and the weld material showed that with an increase in the carbon content in the electrode rod from 0.08 % to 0.8 %, the carbon content in the droplets increases from 0.3 % to 0.97 %. The carbon content in the weld metal is 1.1 %. The assimilation of manganese by a drop increases with an increasing of coating and the droplet interaction time. A significant increasing in the rate of coating melting was obtained. This is due to the fact that the concomitant decrease in the content of graphite in the coating contributes to a decrease in the refractoriness of the electrode coating.
The use of high carbon steels for the manufacturing of electrode rods for welding and surfacing of Gadfield steel improves the properties of the welded metal and sanitary and hygienic parameters.
Reliability-based assessment of the partial factor for shear design of fibre reinforced concrete members without shear reinforcement
Authors: Bairán Jesús Miguel , Tošić Nikola , de la Fuente Albert 
Published: September 2021

AbstractFibre reinforced concrete (FRC) is increasingly used for structural purposes owing to its many benefits, especially in terms of improved overall sustainability of FRC structures relative to traditional reinforced concrete (RC). Such increased structural use of FRC requires safe and reliable models for its design in ultimate limit states (ULS). Particularly important are models for shear strength of FRC members without shear resistance due to the potential of brittle failure. The fib Model Code 2010 contains a model for the shear strength of FRC members without shear reinforcement and the same partial factor accepted for RC structures is accepted for FRC elements. This approach, however, is potentially on the unsafe side since the uncertainties of some design-determining mechanical properties of FRC (i.e., residual flexural strength) are larger than those for RC. Therefore, in this study, a comprehensive reliability-based calibration of the partial factor γc for the shear design of FRC members without shear reinforcement according to the fib Model Code 2010 model is performed. As a first step, the model error δ is assessed on 332 experimental results. Then, a parametric analysis of 700 cases is performed and a relationship between the target failure probability βR and γc is established. The results demonstrate that the current model together with the prescribed value of γc = 1.50 does not comply with the failure probabilities accepted for the different consequences of failure of FRC members over a 50-year service life. Therefore, changes to the shear resistance model are proposed in order to achieve the target failure probabilities.

The aim of our study was to assess the prognostic value of the two new grading systems based on the quantification of tumor budding - TB (GBd) and poorly differentiated clusters - PDCs (PDCs-G) in colorectal carcinomas (CRC). We performed a retrospective study on 71 CRC patients who underwent surgery at the Emergency County Hospital, Timișoara. CRC cases were classified based on haematoxylin-eosin slides, using the conventional grading system, GBd and PDCs-G, respectively. We used two-tier and three-tier grading schemes for each system. Subsequently, we evaluated associations with other prognostic factors in CRC. Based on the three-tier GBd (GBd-3t) most cases (34/69, 49.27%) were classified as G3Bd-3t, while based on the conventional grading system, the majority of the cases (55/69, 79.71%) were considered G2. On the other hand, based on the three-tier PDCs-G system (PDCs-G-3t), most cases (31/69, 44.93%) were PDCs-G2-3t. We also noted a more significant association of GBd-3t with other prognostic parameters analyzed, as compared to the conventional grading system. Nodal status, tumor stage, and lymphovascular invasion were strongly correlated with GBd-3t (p=0.0001). Furthermore, we noted that PDCs-G-3t correlated more significantly than the conventional grading system with nodal status (p<0.0001), tumor stage (p=0.0003), lymphovascular invasion (p<0.0001), perineural invasion (p=0.005) and the tumor border configuration (p<0.0001).
High GBd and PDCs-G grades correlate directly with other negative prognostic factors in CRC.Thus, these new parameters/classification methods could be used as additional tools for risk stratification in patients with CRC.
Before and After: English Language Acquisition in Saudi Arabia and the New Possibilities in Teaching and Learning That the COVID-19 Pandemic May Have Brought
Authors: Alkhannani Badriah M. 
Published: September 2021

This article examines how the teaching and learning of English as a Foreign Language in Saudi Arabia has evolved over time and the new possibilities the COVID-19 pandemic has brought to teaching and learning of English in Saudi Arabia. Various factors have influenced the pace and degree to which the English language has propagated in Saudi Arabia ever since it was first introduced. Learners of English also continue to be affected by several inherent and external factors when learning the English language. On top of having to grapple with first language and culture interferences, learners of English in Saudi Arabia have also to navigate unfavorable learning environments, lack of experiential exposure to English, and foreign language anxiety. Although the COVID-19 pandemic may have seemingly created issues (e.g., a reduction in time for interaction with peers and teachers) for learners of English due to emergency remote teaching, it has opened up new possibilities that can be the subject of additional research and development. The benefits of online learning, translingual practices, and collaborative teaching should be further explored to benefit from the new normal of mandatory online learning that has arisen due to the pandemic.

Abstract: Intellectually disabled children have difficulty understanding abstract things such as Arabic letters. An appropriate learning media that can help them learn is significantly needed. In addition, some Intellectually disabled children can only pronounce Arabic letters but do not know the shape of the Arabic letters. In this context, ABATA media associates and equates Arabic letters with surrounding objects in their form and pronunciation so that intellectually disabled children can know the form and pronunciation of Arabic letters. This research aims to describe the ABATA media and its effectiveness. This research uses narrative review by gathering data from various sources, analyzing and designing the media. ABATA media is designed based on visual media and adopts the analogy method by equating the form of objects with Arabic letters, and the pronunciation of Arabic letters is the same as the initial syllable of objects. Based on the search for various literature sources conducted by the researchers, ABATA media is predicted to be adequate for mentally disabled children in introducing Arabic letters. This is because the visual media and analogy methods that are the basis for developing the ABATA media have proven effective and acceptable to intellectually disabled children. Therefore, ABATA media is believed to make it easier to introduce the shape and pronunciation of Arabic letters.
Keywords: Arabic letters, visual media, analogy, intellectual disability.
