Published: September 2022

The cutter spacing relate to the rock breaking efficiency of the TBM. The double disc cutters rolling marble model is established by using ABAQUS based on the principle of rock breaking specific energy calculation. The effect of the cutter spacing on the amount of the breaking rock is analyzed, and the specific energy of the double disc cutters breaking the rock in different cutter spacing is calculated. The simulation results show that in the geological conditions of marble, when the penetration is 6mm, the cutter spacing is 78mm the specific energy is the smallest. The marble broken experiment was carried out by using the double disc cutters comprehensive test bench. The cutter spacing with the smallest rock breaking energy was about 78mm in the experimental results, which verified the rationality of the simulation model, and was helpful to determine the cutter spacing in different geological conditions and improve the rock breaking efficiency.

Published: September 2022

The purpose of this paper is to overcome the defects of the existing technology, and to solve the problem of calculating the service life of steel wire rope impacted by large tension under a given reliability, a method for calculating the reliable life of steel wire rope impacted by tension based on multi sample diameter degradation is proposed. Firstly, the degradation life threshold of wire rope diameter is determined. Then, the diameter degradation data of several wire rope samples during the test are recorded. Secondly, the random degradation model of the diameter of each steel wire rope test sample is established, and the model parameters are estimated. Thirdly, the multi sample degradation model is modeled by probability fusion. Finally, the reliable life of steel wire rope is calculated according to the probability fusion model. This method, compared with the existing technology, can quantitatively control the reliability and accident probability of the service life of the steel wire rope, solve the problem that the existing methods cannot carry out the regression analysis of multi sample data, and use the degradation data of the diameter of multiple steel wire rope samples with the number of tension impact to evaluate its reliable life.

Authors: Wang Shuai , Sun Nan , Zhuo Chen , Zhou Kaifa , Zheng Xuefeng
Published: September 2022

As a typical hollow thin-wall structure, the crash box still has low energy absorption efficiency and poor anti-collision drawbacks. In order to improve the crash box’s energy absorption and anti-collision performance, two novel UOC (Uniform OC structure) and GOC (Gradient OC structure) are designed by using the orthogonal concave honeycomb structure with a negative Poisson’s ratio. Then the impact dynamics simulation analysis of the two forms is carried out by using ANSYS. The results show that the UOC structure can effectively improve the collision resistance and energy absorption performance of the hollow crash box (HCB), while there are still some problems such as excessive peak impact force and impact reaction force. However, the GOC structure with gradient arrangement can significantly improve the problems existing in UOC structure. The GOC2 structure can reduce the peak impact force of HCB structure by 75.1% and increase the energy absorption capacity by 34.2%, which is the structure with the best anti-collision and energy absorption characteristics.

Authors: Liu Yutong , Kong Zhigang
Published: September 2022

As an important component in electronic equipment, the reliability of electrical connectors determines the life of the entire electronic equipment. Vibration is one of the main factors affecting the reliability of electrical connectors, and the contact pressure of connectors is an important indicator of the reliability of connectors. In this paper, ANSYS simulation is used to study the contact pressure of electrical connectors under static and different vibration conditions. The research results show that the contact pressure becomes smaller under the vibration condition than under the static condition. The increase of the vibration amplitude has little effect on the contact pressure; the increase of the vibration frequency has a great influence on the contact pressure. With the increase of the vibration frequency, the minimum value of the contact pressure decreases.

Published: September 2022

China’s Chang’e 5 mission has been a remarkable success, with the Chang’e 5 lander traveling on the Oceanus Procellarum to collect images of the lunar surface. Over the past half century, people have brought back some lunar rock samples, but its quantity does not meet the need for research. Under current circumstances, people still mainly rely on the analysis of rocks on the lunar surface through the detection of lunar rover. The Oceanus Procellarum, chosen by Chang’e 5 mission, contains various kinds of rock species. Therefore, we first applied to the National Astronomical Observatories of the China under the Chinese Academy of Sciences for the Navigation and Terrain Camera (NaTeCam) of the lunar surface image, and established a lunar surface rock image data set CE5ROCK. The data set contains 100 images, which randomly divided into training, validation and test set. Experimental results show that the identification accuracy testing on convolutional neural network (CNN) models like AlexNet or MobileNet is about to 40.0%. In order to make full use of the global information in Moon images, this paper proposes the MRNet (MoonRockNet) network architecture. The encoding structure of the network uses VGG16 for feature extraction, and the decoding part adds dilated convolution and commonly used U-Net structure on the original VGG16 decoding structure, which is more conducive to identify more refined but more sparsely distributed types of lunar rocks. We have conducted extensive experiments on the established CE5ROCK data set, and the experimental results show that MRNet can achieve more accurate rock type identification, and outperform other existing mainstream algorithms in the identification performance.

Non-ferrous metals play an important role in the national economy, and more and more attention has been paid to their efficient large-scale production. However, the non-ferrous metal production plant environment is bad, the ingot line vibration is violent, the surface of the metal solution also has strong reflective, these adverse factors lead to the automatic detection of the level measurement process in the non-ferrous metal production is very difficult, have to retain a large number of manual links. In order to solve the above problems, an automatic measurement system of non-ferrous metal solution level based on structured light triangulation is established. The system adopts filtering algorithm based on statistics to suppress the adverse effect of ingot line vibration on measurement. At the same time, by increasing the Angle between the optical axis of the camera and the laser plane, the influence of the strong reflection of the solution surface on the measurement can be reduced. The relative error of the system can be controlled within 1.3%, which can meet the actual measurement demand in engineering.

Published: September 2022

Micron particle sorting has an important role in biomedicine, renewable energy, and micro-manufacturing. In this study, a fishbone-shaped micron particle sorting device was designed based on the dielectrophoretic manipulation of micron particles technique. Firstly, the simulation model of multi-physics field coupling is established using experimental data, and the results are calculated and analyzed using the method of finite element analysis. Finally, according to the simulation results, the factors affecting particle manipulation are particle dimensions, number of electrodes, voltage magnitude, and sheath flow rate. Studies have shown that when the sorting particle diameter is different, increasing the sheath flow speed, voltage strength, and the number of electrodes can improve the sorting effect. By modifying the factors affecting the dielectrophoretic manipulation of micron particle sorting, it can make the present design applicable to the sorting of different micron-size particles and provide a significant reference value for the subsequent particle sorting method.

Authors: Zhang Yihan , Gao Baokui , Chen Xingwang , Zhang Yanhuan
Published: September 2022

In order to improve recovery ratio in “Well Factory” development model, spoon-shaped wells are introduced. Spoon-shaped wells need a reverse hole extension with deviate and azimuth change before forward drilling. The complicated well trajectory leads to larger drag on the working string during the string slacking off and pulling up. In order to analyze the friction characteristics of downhole string, software is developed. Case study shows that spoon-shaped hole section makes it more difficult for the working string to slack off and pull up than an ordinary horizontal well. The software calculates the axial force, and the in-depth analysis concludes that the contact force between string and borehole wall in the forward deviation-built section is very large, especially in the section that deviation and azimuth change; large target section deviation increases the contact force.

Published: September 2022

Feline enteric coronavirus (FECV) infects enterocytes and causes inflammation of the intestinal mucosa in young cats, resulting in diarrhea. In adult cats the infection is usually asymptomatic, but the constant circulation of FECV in the feline population increases the likelihood of mutation, as a result of which about 5-10% of infected cats develop a virulent strain of the virus that causes usually lethal feline infectious peritonitis – FIP. The purpose of this study was to study the effectiveness of Phosprenyl (PP), an immunomodulator with antiviral activity (active substance - polyprenyl phosphate), in the treatment of chronic coronavirus infection of cats, partially complicated by toxoplasmosis.

A total of 117 cats were under observation, 10 of which also had toxoplasmosis. The diagnosis was confirmed by the determination of antibodies by the methods of IHA and ELISA, as well as by ultrasound examination of the abdominal organs. Prescribed treatment: Phosprenyl per os, 1 ml , twice a day, course 2-4 months; Gamavit daily, s/c, course 10 days, with a repeated course after 3 weeks; 3-4 times. As symptomatic therapy, drugs were used primarily to improve the condition of the stool, with toxoplasmosis - Fansidar. At the end of treatment symptoms of gastrointestinal tract damage disappeared in all the patients. If before the start of therapy, the majority of patients demonstrated changes characteristic of anemia (a significant decrease in the number of red blood cells and hemoglobin levels), then after 2-4 months, the indices of erythropoiesis completely normalized. In patients with coronavirus infection complicated by toxoplasmosis, anemia was detected by CBC test, as well as an increase in the number of neutrophils. In the biochemical profile of these patients: increased activity of the enzymes aspartate aminotransferase (AST) and alanine aminotransferase (ALT) was found as well as hyperbilirubinemia, which indicates greater liver damage and a decrease in its detoxification function during the course of the disease caused simultaneously by coronavirus and toxoplasmas. At the end of therapy, these indices also returned to normal.

Thus, the use of Phosprenyl for 2-4 months reduces the duration of the disease of coronavirus infection in cats (including cases complicated by toxoplasmosis), prevents its exacerbation and possible fatal outcome. Long-term use of PP in cats with a chronic form of coronavirus infection is recommended.
Stressed out: stressed out! Implications of minority status stress among underrepresented minority BSN students
Authors:   , McGee Eve
Published: September 2022

This study explored and described the prevalence of perceived stress and minority status stress levels among undergraduate Bachelor of Science in Nursing (BSN) students and their relationship to academic persistence. Two research questions motivate this study: 1) What are the differences in perceived stress levels between underrepresented minority (URM) and White BSN students, and 2) What is the relationship between minority status stress (MSS) and the persistence attitudes of URM BSN students. It was hypothesized that: 1) URM BSN students experience stress related to minority status, and 2) the additive levels of perceived MSS will be significantly related to academic persistence attitudes. Previous research studies utilize traditional models of stress and coping in a sample of predominately White, young, traditional college students. Therefore, the unique stressors related to one's minority status are not examined. This study advances our understanding of stress among URM BSN students and proposes a conceptual framework in which to analyze the problem, thus allowing social workers to understand the context of stress in marginalized groups holistically. A quantitative, cross-sectional survey design study was conducted. Using a convenience sample (N=99), we collected data from three four-year, public, accredited BSN programs in the Midwestern region of the United States. The findings from this research study show the impact of parental income and mother's level of education upon academic persistence attitudes. Underrepresented minority students experience minority status stress. The findings offer insight for social workers, nursing school administrators, and student affairs personnel in better understanding the relationship between MSS and academic persistence.

Authors: Ibrahim Anwar , Ali Hikmat , Rasheed Razan
Published: September 2022

Designing zero or near zero-energy residential buildings will considerably help in reducing the general energy consumption. Geographically, Jordan retains three different altitude zones with unique climatic conditions for each which imperatively entails deploying different approaches to attain near zero-energy houses. This study aims to investigate the best economic feasible design strategies that possibly lead to near zero-energy residential buildings. Based on the most common detached house design-layout and materials on each zone, three case study houses were designed. The research methodology was based on three levels of efficiency. By using Design Builder, each efficiency level was examined by three design strategies: passive, active, and renewable energy design strategies in order to improve the energy performance of the buildings. The results showed that implementing the three levels concurrently would result in achieving the nearly zero-energy houses with efficient cost and less than 10 years payback period.  In the high-land altitude zone, the annual consumption of power was reduced from 79.1 kwh/m2 to -13.6 kwh/m2. For the medium altitude zone, the annual consumption dropped down from 78.8 kwh/m2 to -16.5 kwh/m2. Finally, the annual consumption of electricity in the low-latitude zone decreased from 75.7 kwh/m2 to -21.1 kwh/m2.

Authors: ÖZKAN Muhittin , DURU BAYKAL Pınar , ÖZKAN İlkan
Published: September 2022

It is common to use open-end rotor yarn in the production of denim fabric, which is preferred by people of all ages and social status due to its durability and comfort. Recently, the demand for stretch denim fabrics that can take the body's shape due to the elastic fibers in its structure has been increasing. However, producing elastane-containing yarns in the rotor spinning system is not as practical as ring spinning. For this reason, this study aimed to use the staple Sustans® fibers with high elasticity in the rotor spinning system together with cotton fibers and reflect the good elasticity and elongation properties of Sustans® fibers to the rotor yarns and denim fabrics. In the study, the staple Sustans® fibers based on PTT (Polytrimethylene Terephthalate) were spun with cotton fibers in the rotor spinning system. Then denim fabrics were produced using these yarns in the weft. Later, strength (breaking and tear), dimensional stability (dimensional change after washing, fabric elasticity and growth), abrasion resistance and pilling tests were applied to the produced denim fabrics. Thus, the effects of using Sustans® fibers on the strength, dimensional stability, abrasion and pilling properties of denim fabrics were analyzed. As a result of the study, the dimensional change and growth values after washing were developed by using Sustans®. Although good dimensional stability was observed in the samples, the degree of elasticity was lower than expected. The use of Sustans® at rates of 50% and above improved the pilling values of the fabrics. In addition, it has been determined that the use of Sustans® in terms of abrasion resistance has a more positive effect at the end of long wear periods.

The development of urban areas occurs due to the demands for space for activities from the community. Increased activity in the city center has an impact on increasing the need for housing. Kampong Batan is one of the settlements located in the downtown triangle area of Pandanaran road, Pemuda road and Gajah Mada road (PANDAMA). Kampong Batan is also one of the old kampongs that experienced the growth of residential areas due to the development of activities. The implication of the development of activities in the city center to Kampong Batan is experiencing changes that are seen physically and non-physically. In this study, we will examine the characteristics of the Batan settlement in Semarang City in order to find out the changes that occur due to the development of activities in the city center. The research method used is field observation by looking at the development of Kampong Batan from the colonial era to the present based on the map of the previous year of Semarang City. Then it is identified the changes that occur based on the road network, changes in the use of residential space and the characteristics of the settlements. The result is that the settlement of Old Kampong Batan began to be filled with settlements from 1925 to 2000. The changes that are happening today can be seen from the expansion of residential activity space into a terrace, for parking and as a place to sell. In addition, many changes in the area that were previously only areas with residential functions have now turned into trade and service functions.

Published: September 2022

Changes in land use are closely related to the increasing number of people who are increasing from time to time. This land use change has an impact on increasing the runoff coefficient because the rain that falls will not be retained or seep and flows directly into the river. This is what causes an increase in peak discharge in a watershed. The purpose of this study was to determine the magnitude of changes in peak discharge that occurred in the Serenan watershed in 2015 and 2021 due to changes in land use. The method used in analyzing the peak discharge is the Snyder unit hydrograph, the results of this method will be compared with the measured unit hydrograph to determine the correlation between the two. To make a synthetic unit hydrograph, non-physical parameters are needed in the form of Ct and Cp values. The Ct value used in 2015 was 2.30 and in 2021 it was 2.00 while the Cp value in 2015 was 0.90 and in 2021 it was 1.10. The results of the analysis using the Snyder method showed that the peak discharge was 139.61 m3/s in 2015 and 194.56 m3/s in 2021. The analysis shows that the peak discharge increased by 54.95 m3/s and has a very strong correlation with the hydrograph of the measured unit.

Traditional settlement patterns are often represented as places that still hold traditional and cultural values in everyday life that are related to beliefs or religions that are special or unique in a particular community rooted in a place outside of historical determination that supports tourist villages. . This research was conducted in Pengotan Village, which has a unique cultural dedication tourism village with traditional Balinese architectural settlements, culture and customs in Pengotan Traditional Village, Bangli. Pengotan Village is a Bali Aga village, one of which still maintains traditional mountain village values using the Tri Angga (Hulu-teben) settlement concept. This study uses a qualitative method with a case study approach. The purpose of this study is to analyze the opportunities for the development of Traditional Village Customary settlements which are supporting elements of a Traditional Village into a Tourism Village, as well as the challenges that occur in a Traditional Village after its development into a Tourism Village.

Concrete durability is the ability of concrete to last as it was originally planned, in the structure of a building can be defined as the ability to maintain function, stability and aesthetics due to environmental influences so as not to incur large maintenance and repair costs during the planned service life. The durability aspect is very important, especially for infrastructure that has a fairly long service life. Building life is the period or time during which a structure is required to continue to function as planned. In building structures whose construction has been completed, both new and old buildings, specific data related to the quality of the concrete and the planned age of the building is quite difficult to obtain, this is because the influence during the implementation of construction is also not good in governance. documentation, both technical documents and other non-technical documents, therefore it is necessary to have a sufficiently representative tool to test the concrete quality of a building that has been completed to comply with the quality of the built concrete.
Shame mediates the relationship between negative trauma attributions and Posttraumatic Stress Disorder (PTSD) symptoms in a trauma exposed sample
Authors: Seah Rebecca , Berle David
Published: September 2022

Background

Theoretical models of self-conscious emotions indicate that shame is elicited through internal, stable, and global causal attributions of the precipitating event. The current study aimed to investigate whether these negative attributions are related to trauma-related shame and PTSD symptom severity.

Method

A total of 658 participants aged 18 to 89 (M = 33.42; SD = 12.17) with a history of trauma exposure completed a range of self-report measures assessing trauma exposure, negative trauma-related attributions, shame, and PTSD symptoms.

Results

Higher levels of internal, stable, and global trauma-related attributions were significantly associated with shame and PTSD. Shame mediated the association between trauma-related attributions and PTSD symptom severity, even after controlling for the effects of number of trauma exposures, worst index trauma and depression.

Conclusions

The present results suggest that negative attributions are a critical cognitive component related to shame and in turn, PTSD symptom severity. Future research should aim to replicate these findings in a clinical sample and extend these findings using prospective designs.
Effects of Balanced Ligamentous Osteopathic Technique over LV in low back pain
Authors: Schenone L. E.
Published: September 2022

Due to the high incidence of non-speciﬁc low back pain in the world population that don′t present a response with conventional tools, a quantitative register is sought, through a Balanced Ligamentous Osteopathic Technique, that responds to its effectiveness on the ligaments iliolumbar elongated by the vertebral injury, that is, the correction of a second-degree injury of the 5th lumbar. The purpose of this study was to determine if there is a decrease in local pain and an increase in trunk ﬂexion movement in Lumbosacral Hinge after applying the Balanced Ligament Osteopathic Technique on the transverse apophysis of the 5th lumbar and to emphasize the importance of the treatment of ligament structures in the speciﬁc biomechanical integration of the entire spine. This design consisted of two groups, an experimental one that received the treatment detailed in the present work, while the second group was the control group, which received a placebo intervention. It was made up of two groups, one of an experimental type, of 72 participants, who received the treatment detailed in the present work, while the second group of other 72 participants, was the control group, which received a placebo intervention. Quantitative pain values were taken through the Algometer (local pain) and the ground ﬁnger test to record the presence of the limits that pain generates for the trunk ﬂexion movement. The ground ﬁnger test resulted in an increase of 62,6 % for the experimental group and 6.7% for the control group, before and after the intervention. The same occurred in the Algometer record before and after the intervention, giving a 133 % increase in tolerance to pressure in the experimental group and in the control group it did not exceed 1 %.
Justifi cation of the use of osteopathic correction in the planned preparation of patients for general anesthesia with tracheal intubation

Introduction. The risk of unsuccessful intubation is a signifi cant problem during elective surgical operations with general anesthesia and tracheal intubation. Taking in consideration the trend towards the development of short-stay surgical hospitals, and the rather low availability of endoscopy services, the search for alternative methods of preparing patients for successful tracheal intubation is in demand. A normal tone of the muscles involved in the work of the temporomandibular joints as well as the tone of the muscles above the hyoid bone and the muscles below the hyoid bone are necessary for successful intubation of the trachea. Based on modern ideas, it can be assumed that an adequate osteopathic effect on the mentioned anatomical structures can provide a decrease in muscle tone. However, there are no publications in the available literature on osteopathic correction of patients at high risk of intubation in order to reduce the risk degree.

The aim of the research is to substantiate the use of osteopathic correction in the planned preparation of patients for general anesthesia with tracheal intubation.

Materials and methods. The study involved 30 patients with chronic surgical pathology of internal organs who had to undergo elective surgery. The patients were distributed into the control and main groups (15 participants each) by the method of randomization envelopes. The participants of the control group followed the instructions given by the anesthetist, the participants of the main group received additionally a month before the operation two sessions of osteopathic correction with an interval of 14 days. In both groups, the osteopathic status was assessed before the start of the corresponding treatment. The degree of intubation risk and the incision distance were also assessed. After completion of the corresponding treatment, the osteopathic status was re-evaluated in both groups. In the main group, the risk of intubation and the incision distance were re-evaluated.

Results. At the beginning of the study, both groups were characterized by a high detection frequency of the following regional biomechanical disorders: neck, thoracic region and dura mater. At the completion of the study, a statistically signifi cant (p<0,05) decrease in the detection frequency of all these disorders was observed in the main group. There was no signifi cant dynamics in the control group. Also in the main group there was a statistically signifi cant (p<0,05) decrease in the intubation risk and an increase in the incision distance value.

Conclusion. The obtained results allow recommending the appointment of an osteopath consultation and osteopathic correction during the planned preparation of patients with a high risk of intubation. At the same time, it is recommended to continue the study on a larger sample.
