LPBF Manufactured Functionally Graded Lattice Structures Obtained by Graded Density and Hybrid Poisson’s Ratio
Authors: Abdelaal Osama , Hengsbach Florian , Schaper Mirko , Hoyer Kay-Peter
Published: June 2022

The additive manufacturing (AM) of innovative lattice structures with unique mechanical properties has received widespread attention due to the capability of AM processes to fabricate freeform and intricate structures. The most common way to characterize the additively manufactured lattice structures is via the uniaxial compression test. However, although there are many applications for which lattice structures are designed for bending (e.g., sandwich panels cores and some medical implants), limited attention has been paid toward investigating the flexural behavior of metallic AM lattice structures with tunable internal architectures. The purpose of this study was to experimentally investigate the flexural behavior of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio (PR). Four configurations of lattice structure beams with positive, negative, hybrid PR, and a novel hybrid PR with graded density were manufactured via the laser powder bed fusion (LPBF) AM process and tested under four-point bending. The manufacturability, microstructure, micro-hardness, and flexural properties of the lattices were evaluated. During the bending tests, different failure mechanisms were observed, which were highly dependent on the type of lattice geometry. The best response in terms of absorbed energy was obtained for the functionally graded hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the positive PR (PPR) structure. This highlights the great potential for FGHPR lattices to be used in protective devices, load-bearing medical implants, and energy-absorbing applications.
Using Pose-Dependent Model Predictive Control for Path Tracking with Bounded Tensions in a 3-DOF Spatial Cable Suspended Parallel Robot
Authors: Bettega Jason , Richiedei Dario , Trevisani Alberto
Published: June 2022

This paper proposes the preliminary results on a novel control architecture based on model predictive control (MPC) for cable-driven parallel robots (CDPRs) and applies them to a three degrees of freedom (3-DOF) robot with a suspended configuration, leading to a cable-suspended parallel robot (CSPR). The goal of the control scheme is ensuring accurate path tracking of the reference end-effector path, while imposing a priori positive cable tensions. To handle the nonlinearities characterizing the dynamic model that governs this kind of multibody system and to keep the computational effort low, a position-dependent MPC algorithm with an embedded integrator is designed to compute the optimal cable tensions required to track the end-effector commanded path. Such tensions must belong to the feasible domain defined through a lower bound, which is slightly greater than zero, to ensure that cables pull the end-effector, and an upper bound, to represent the maximum stress that cables can withstand without breaking. The resulting controller is nonlinear, although it performs a local linearization in the prediction at each time step to reduce the computational effort. The optimal tensions are then transformed into the commanded motor torques through the inverse dynamic model of the servomotors driving the winches, since no force measurement is adopted in the controller implementation. The control architecture is designed and numerically validated through a spatial CSPR with lumped end-effector, and driven by three cables (i.e., with a non-redundant configuration). Four different paths are assumed to highlight various features of the proposed controller.
Anomaly Data Detection of Rolling Element Bearings Vibration Signal Based on Parameter Optimization Isolation Forest
Authors: Wang Haiming , Li Qiang , Liu Yongqiang , Yang Shaopu
Published: June 2022

Anomaly data detection is not only an important part of the condition monitoring process of rolling element bearings, but also the premise of data cleaning, compensation and mining. Aiming at the abnormal data segment detection of the vibration signals of a rolling element bearing, this paper proposes an abnormal data detection model based on comprehensive features and parameter optimization isolation forest (CF-POIF), which can adaptively identify abnormal data segments. First, in order to extract the mutation feature of vibration signals more accurately, the concept of comprehensive feature is proposed, which integrates the time domain and wavelet packet energy features. Then, the particle swarm optimization (PSO) algorithm is used to optimize the rectangular window length and sub sample set capacity in the isolation forest for anomaly detection. Finally, three real cases concerning abnormal data are used to verify the effectiveness of the proposed method. The results demonstrate that the proposed method is able to detect missing data, drift data and external interference data effectively, and it has a higher F1 score and accuracy compared to other methods.
A Cycle Analysis of Flow and Thermal Parameters in the Hydrogen Charging System at the Pressure of 50 MPa
Authors: Li Ji-Qiang , Song Byung-Hee , Kwon Jeong-Tae
Published: June 2022

In the currently developed hydrogen compression cycle system, hydrogen is compressed through a compressor and stored in a tank at high pressure. In the filling process from A (tube trailer) to B (high-pressure tank), thermal stress in the B arises due to the temperature rise of hydrogen together with the internal pressure increase in the tank. In the study, in order to achieve safe filling, it is necessary to investigate the flow and thermal parameters of the system. Based on the principles of thermodynamics, a thermodynamic prediction model for the temperature change during the hydrogen cycle was established by comprehensively considering the real state of gas, convective heat transfer between hydrogen and the inner wall, heat conduction through the tank wall, and natural convection of the outer wall. Prediction values of temperature, hydrogen charge amountm and heat transfer to the outside were calculated. Additionally, by investigating the performance of the hydrogen refueling station heat exchanger, the heat of the heat exchanger needed to keep the hydrogen temperature within a safe range was calculated. Due to the Joule–Thomson effect, the hydrogen temperature passing through the pressure reducing valve changed, and the changed value in the hydrogen charging cycle was predicted and calculated by calculating the temperature change value at this time. This study provides a theoretical research basis for high-pressure hydrogen energy storage and hydrogenation technology.
Control of Molecular Orientation and Carrier Transport of Thiophene-Based Semiconducting Polymer via Superparamagnetic Nanoparticles Fe3O4@C-Assisted Magnetic Alignment Method
Authors: Hui Di , Li Tian , Ye Chun , Pan Guoxing
Published: June 2022

Realizing the high molecular orientation and structurally ordered microstructure of organic semiconductor polymer thin films is beneficial for enhancing the charge transport of conjugated polymers and achieving high-performance organic electronic devices. In this work, we successfully developed large-area highly aligned films of a thiophene-based polymer, namely poly(2,5-bis(3-alkylthiophen-2-yl) thieno [3,2-b] thiophene) (PBTTT), using the magnetic alignment method at a low magnetic field (0.12 T), which was assisted by superparamagnetic nanoparticles Fe3O4@C. The aligned microstructure of the composite films is confirmed by systematic analysis that includes polarized optical microscopy, polarized UV–visible absorption spectroscopy, and an atomic force microscope. Organic field effect transistors based on magnetic aligned composite film exhibit a 2.8-fold improvement in carrier mobility compared with the unaligned films. We hold a formation mechanism that the rapid magnetically induced self-assembly property of Fe3O4@C and its intermolecular interaction with polymer chains are key to the new method of preparing oriented thin films.

Published: June 2022

Carbohydrate-active enzymes (CAZymes) are an important characteristic of bacteria in marine systems. We herein describe the CAZymes of Paenibacillus algicola HB172198T, a novel type species isolated from brown algae in Qishui Bay, Hainan, China. The genome of strain HB172198T is a 4,475,055 bp circular chromosome with an average GC content of 51.2%. Analysis of the nucleotide sequences of the predicted genes shows that strain HB172198T encodes 191 CAZymes. Abundant putative enzymes involved in the degradation of polysaccharides were identified, such as alginate lyase, agarase, carrageenase, xanthanase, xylanase, amylases, cellulase, chitinase, fucosidase and glucanase. Four of the putative polysaccharide lyases from families 7, 15 and 38 were involved in alginate degradation. The alginate lyases of strain HB172198T exhibited the maximum activity 152 U/mL at 50 °C and pH 8.0, and were relatively stable at pH 7.0 and temperatures lower than 40 °C. The average degree of polymerization (DP) of the sodium alginate oligosaccharide (AOS) degraded by the partially purified alginate lyases remained around 14.2, and the thin layer chromatography (TCL) analysis indicated that it contained DP2-DP8 oligosaccharides. The complete genome sequence of P. algicola HB172198T will enrich our knowledge of the mechanism of polysaccharide lyase production and provide insights into its potential applications in the degradation of polysaccharides such as alginate.
Changing environment and orchid distributions close to their northern and southern limits in Britain
Authors: Trudgill David
Published: June 2022

The total numbers of tetrad records in the BSBI database collected for 20 species of British orchids in the period 1970-86 were compared with those collected in 2010-19. The species chosen had a northern limit to their distributions somewhere in Britain and comparisons were restricted to changes close to their northern and southern distribution limits. In a 100 km band close to their northern limit, recorded tetrad occupancy decreased for 14 species by a mean of 34% between the two date-classes. Despite Britain warming by 0.9 C° over this period, four species had retreated southwards, and only Ophrys apifera (Bee Orchid) and Anacamptis pyramidalis (Pyramidal Orchid) had significantly extended their distributions northwards. Changes in tetrad occupancy were also explored in a similar band immediately to the north of the southern tip of the Isle of Wight. Here, tetrad occupancy decreased for 10 of the 20 species by a mean of 33%. In both the northern and southern bands, where a species was recorded in 1970-86, on average in 2010-19 it was re-recorded in only c.40% of tetrads. There were large differences between species in apparent rates of colonization of new tetrads. This accounted for most of the differences between species that increased their tetrad occupancy between the two date-classes and those that declined. No account was taken of the increase in the intensity of recording between 1970-86 and 2010-19 but these results provide further strong evidence of the decline of many orchid species, especially in England.

Published: June 2022

The bacteria found in the sputum of patients with cough due to respiratory tract infections are Streptococcus bacteria and Staphylococcus aureus. Symptoms of cough can be treated with herbal remedies, one of which is drinking water from fruit juices, vegetables, herbs, and spices or what is later known as infused water. Plants that are believed to be able to inhibit bacterial growth are white ginger (Zingiber officinale var. amarum) because based on the results of phytochemical identification, ginger contains essential oil compounds and phenolic compounds that are antibacterial. This research aims to determine the inhibition of white ginger infused water on the growth of Staphylococcus sp. This research is a True Experiment with Completely Randomized Design (CRD),  with white ginger infused water treatment with various concentrations. The results of the isolation and identification of sputum samples found Staphylococcus sp. The results of the sensitivity test of white ginger infused water as an antibacterial against Staphylococcus sp at all concentrations of 100%, 80%, 60%, and 40% were unable to inhibit the growth of Staphylococcus sp. The results showed that white ginger (Zingiber officinale var. amarum) infused water had no effect on inhibiting the growth of Staphylococcus sp.

THE NOVEL MARKER OF REACTIVE HEPATITIS IN INJURED WITH GUNSHOT WOUNDS
Authors: Osodlo G. V. , Savichan K. V.
Published: June 2022

Objective. The aim of the study was to improve the diagnosis of reactive hepatitis in injured with gunshot wounds.

Methods. A retrospective analysis of 373 medical histories of servicemen wounded during the war in eastern Ukraine in 2014-2020, 233 of whom were hospitalized at the National Military Medical Clinical Center (NMMCC) and military medical clinical centres of the North, South, Eastern regions of the Ministry of Defense of Ukraine for more than 14 days. All servicemen had laboratory examinations using unified methods of laboratory tests. The obtained data were processed using non-parametric statistical methods.

Results. The median baseline of ALT and, to a greater extent, AST (in the first period of traumatic illness) exceeds the upper limit of normal (40 IU / l). The highest values ​​of ALT were observed in the second period of traumatic illness on the 5th and 10th day of observation with a slight decrease in the next stage of the study. The concentration of AST increased significantly in the first period of traumatic illness, almost did not decrease in the second period, but approached normal values ​​≥14 days after injury. The strongest correlation between transaminases and albumin levels was found. A new calculated indicator in the form of the ratio of ALT concentration to albumin concentration (coefficient of reactive hepatitis of the injured, CRGI) is proposed. The development of post-traumatic reactive hepatitis was confirmed in all cases with the wounded with the value of CRGI ≥2.0.

Conclusions.

1. Based on a retrospective analysis of 373 case histories of wounded in different periods after a gunshot wound, a new calculated indicator is proposed - the coefficient of reactive hepatitis of the injured (CRGI) in the form of the ratio of ALT/albumin concentrations, the increase of which indicates hepatocellular damage of hepatocytes with simultaneous suppression of the protein-synthetic function of the liver on the background of catabolic reactions.

2. CRGI ≥2 indicates the development of reactive hepatitis, is most often observed in the second period of traumatic illness and tends to normalize in the background of effective treatment. In the wounded who died as a result of injuries, CRGI steadily increased and was significantly higher than in the wounded with the uncomplicated course, especially in the third period of traumatic illness - after 14 days or more (4.0 vs. 2.3, respectively), which indicates the possible use of the proposed indicator as a prognostic criterion for worsening the prognosis in the wounded.

Objective(s). The aim is to determine the possibilities of optical coherence tomography (OCT), optical coherence tomography angiography (OCTA) of the eye in the diagnosis of tuberous sclerosis and to assess the dynamics of this rare pathological process.

Methods. The clinical case of a 19-year-old patient with tuberous sclerosis with involvement in the pathological process of the visual organ is presented. Ophthalmological examination and also examination of related specialists are carried out. Visual acuity was of the right eye was 1.0 and of the left eye was 1.0 with correction. One pathological focus was detected on the right eye during ophthalmoscopy. Two focuses were revealed on the left eye. OCT and OCTA of the eye were performed on the device Optovue RTVue 100 XR Avanti (Optovue Inc, USA). OCT was analyzed in different modes. Automatic and manual segmentation were used in OCTA analysis.

Results. OCT of the retina allowed to visualize homogeneous formations at the level of the inner layers of the neuroepithelium in the areas detected by ophthalmoscopy, and to exclude from the pathological process of the vitreous and choroid. The foci had clear boundaries and protruded into the vitreous. The retinal layers under the foci were dislocated and thinned, but the structure of all layers was clearly visible. Manual segmentation of OCTA showed a change in the location of large vessels of the superficial plexus and allowed to exclude the growth of abnormal vessels. Differential diagnosis was performed with retinoblastoma and inflammatory diseases, such as chorioretinitis. Confirmation of the type of phacomatosis in the patient was obtained by examination of other organs. The patient had 4 primary signs and 2 secondary signs of tuberous sclerosis.

Conclusion. The use of OCT and OCTA allowed to segment the retina and choroid, localize the pathological process and detect signs of retinal hamartoma. Identified primary and secondary signs of tuberous sclerosis in combination with ophthalmic manifestations (presence of retinal hamartomas) made it possible to establish the diagnosis.

Published: June 2022

The impact of the ultraviolet radiation index is becoming more intense and dangerous for the health of the epidermis and eyesight of people, especially for farmers in the Chirinche Bajo (Ecuador) community. Farmers are exposed to the intense sun during their work days in the crops, for this reason, a technological system based on the Internet of Things (IoT) was proposed to inform them of the UV index to which they are exposed and take precautions to go out to do their daily work. A monitoring device was developed and an application in the API of the Thinger.io platform to visualize and manage alarms. During the monitoring time, the system detected a UV index higher than 9 in the morning and afternoon hours (11am to 1pm), which according to the World Health Organization (WHO), is classified as very dangerous: it recommends wearing clothing that covers most of the body, sunscreen, a hat and sunglasses. In the community, the farmers use their traditional hat, which does not cover their faces optimally, and due to the lack of economy, they do not use sunscreen. The project is an initial contribution to create a culture of information and technological development in rural agricultural areas of Ecuador.

Published: June 2022

Aim: The purpose of this study is to investigate the association between
maternal serum levels of alpha-fetoprotein (AFP), human chorionic
gonadotropin (HCG), unconjugatedestriol (uE3) and poor pregnancy
outcomes, determine whether these markers are effective predictors of
poor pregnancy outcomes and to compare their levels in women with
prior cesarean section and no prior uterine surgery.
Material and Methods: Women with cesarean section due to a previous
uterine surgery (n= 87) and women with no prior uterine surgery and
performed vaginal delivery (n= 105) whose prenatal care was performed
in the same clinic were included. Second trimester maternal serum
levels of AFP, HCG and uE3, as well as multiples of the median (MoM) of
these markers were evaluated. Differences in biochemical marker levels
between groups and their relationship to poor maternal-fetal outcomes
were assessed.
Results: AFP, HCG, and uE3 levels of second trimester screening test
markers, no statistically significant difference was found between the
groups. When both groups are evaluated together, there is a negative,
statistically significant association between neonatal weight and AFP
level. When comparing the presence of fetal complications and the
biochemical markers of the second trimester screening test HCG and
E3, no statistically significant difference was observed. It was found that
AFP levels of cases with fetal complications were statistically significantly
higher than those of cases without fetal complications (p<0.01).
Conclusion: While high AFP-MoM levels may be a warning of fetal
complications, second trimester screening test markers were found to
be insufficient to predict maternal complications. The levels of these
markers was not different between women with prior cesarean section
or no prior uterine surgery. Conducting this study with a larger sample
could provide further valuable information.

Green Technology Financing Scheme (GTFS) Utilisation – an Application of UTAUT2 Model in Non-Technology Context
Authors: Ahmad Noryati , Mustaffa Abd Hadi , Bahrudin Nur Zahidah
Published: June 2022

The Malaysian government has provided green financing initiatives to encourage companies to embark on those projects. One of the green financing initiatives is the introduction of the Green Technology Financing Scheme (GTFS). The scheme has been offered since 2010, and RM 3.5 billion allocated funds have been utilised within seven years. Despite the huge amount of funds being allocated, the utilisation of the funds has been relatively slow and underutilised. Preliminary observations indicate that the cause is mainly the perceived risk that hinders users or borrowers from participating in the financing package. In addition, there seems to be a vast distance between application approval and rejection volume among the users because applicants cannot meet the technical requirement, and GTFS is an unattractive financing package. Thus, GTFS is considered high risk with little or no success story in the past. There are two objectives of the study. First, to analyse the Green Financing trend in Malaysia. First, to examine the relationship between the determinants with the intention to utilise and utilization behaviour of GTFS in Malaysia. Second, to determine if perceived risk moderates the relationship between performance expectancy with intention, and effort expectancy with intention to utilise GTFS in Malaysia.

As a Muslim individual who lives in a Muslim-majority country, of course, it is necessary to pay attention to brand, halal label and product composition of cosmetics. The development of technology also encourages the creation of new products, which makes people have to be more selective in choosing brand, halal products and consist of natural or organic ingredients in accordance with Islamic law. The purpose of this study was to determine the effect of brand perception, halal label and product composition of cosmetics to habitual buying behaviour. This research was conducted on 169 respondents using SPSS ver.26 and PROCESS macro v.4 model 4 for data analysis and to determine the effect of mediation. The results of this study indicate that brand perceptions, halal labels and product composition of ingredients affect habitual buying behaviour. However, the most influential variables in this research are product composition and halal label. While brand perception contributes only 1% and is negative. The reason is a healthy and safe product composition will increase consumer confidence to buy repeatedly. In addition, the inclusion of halal labels is important not only for consumers, but also for producers. This halal label is intended to provide a sense of security for consumers. Also, as a guarantee for them that produced in a halal and ethical. Price can signal product quality, represent elegance and status, while people tend not to pay attention to brands.

Government Policy and Practices to Support Malaysian Food Donors in Redistribution of Surplus Food. Are there sufficient?
Authors: Hamik Saidatul Akma , Mohamed Ahmad Fariz
Published: June 2022

Food waste has been described as a global problem with numerous root causes (Minor et al., 2019; Narvanen et al., 2020; Niina et al., 2022; Weber and Khademian, 2008). Food waste has reached alarming proportions, with approximately one-third of all food produced going to waste (FAO, 2014; Gustavsson et al., 2011). Food waste accounts for 20% of all food produced in the European Union(EU), costing 143 billion EUR annum (Stenmarck et al., 2016). A study was done by Future Directions International (FDI) in 2016 found that 25% of the globe's food waste happens in South and Southeast Asia. Food waste prevention at the source must be the main priority. Still, the EU's food waste hierarchy puts redistribution of surplus food for human consumption as the second-best option when food waste cannot be avoided (European Commission, 2020). Some Southeast Asia countries managed 64% of avoidable food waste by redistributing it to those in need (Tech Collective, 2019). Most food waste is managed via lower-priority methods, including composting, incineration, or landfill (European Comission, 2020; Eurostat, 2020; Obersteiner et al., 2021). Redistribution of surplus food or food donation to a marginalised community can be advantageous. Aside from the environmental, economic and social benefits, using the food for its intended purpose preserves its energy and nutrient content. Furthermore, surplus food redistribution is increasingly recognised to address food insecurity and food waste (Schneider, 2013). In Malaysia, the government is concerned with redistributing surplus food operated by a food bank or charity organisation via donations from the food retail industry (Hamik et al., 2021).

Change in surface properties of hemoglobin induced by heme reaction with O2 and CO
Authors: Maehira Ai , Che Dock-Chil , Matsumoto Takuya
Published: June 2022

The surface properties of hemoglobin bound to O2 (HbO2) or CO (HbCO) were investigated by ethanol precipitation, particle size analysis, and ζ potential measurements. We found that, compared with HbO2, HbCO is surrounded by more hydration water molecules, resulting in the greater physicochemical stability of HbCO in aqueous conditions. The intermolecular interactions of HbO2 and HbCO were studied by acquiring atomic force microscopy images under ambient air conditions. HbCO molecules easily aggregated on the hydrophilic mica substrate compared with HbO2 molecules during the dewetting process. We discuss these results in terms of a competing process between dispersion forces and adsorption on the hydrophilic mica substrate. The observed results suggest that the local structural differences between Fe–O2 and Fe–CO influence the surface structure of the protein, leading to the observed dissimilar physicochemical properties of HbO2 and HbCO.

Aircraft maintenance is an essential cost borne by the airline. Improving maintenance practices for day-to-day operations can lead to significant financial savings. The benefits of effective maintenance are derived from the avoided costs caused by unexpected breakdowns and from maximising aircraft flight time transporting passengers.  The fuel system is a crucial part of the entire aircraft as it ensures delivery of the fuel to the engine and a key component within this system are the fuel pumps. These airborne fuel pumps are classified between the pumps installed in the airframe fuel system and in the engine fuel system. Past works have investigated the performance characteristics of these pumps during flight, however there are no reviews related to the present Health Monitoring (HM) capabilities under flight conditions. HM refers to the field of diagnosing faults or predicting the remaining useful life (RUL) of the pump and the focus of this review is to highlight the HM technologies suitable for aircraft fuel pumps. This is done by first reviewing the technologies and concepts related to HM of fuel pumps. Second a literature review is carried out on pump and motor faults is carried out, drawing on examples from aerospace and other relevant industries. Section 6: Conclusion, discusses the HM technologies have been applied to aerospace fuel pumps and highlights the gaps in capabilities, based on the findings of the literature review carried out in Section 4: Common Faults and Section 5: HM Sensing Methods to suggest future developments in this field. It was found that there is a large scope for development for the HM airframe fuel pumps, based on reviewing the present state of the art. Furthermore, there are no clear strategies formulated by airframe manufacturers and equipment suppliers to test and implement existing HM solutions to operate under flight conditions. This highlights the need to develop HM in this field and a requirement for further research to allow this technology to be a part of routine aircraft
