Foot Orthosis and Sensorized House Slipper by 3D Printing
Authors: Brognara Lorenzo , Fantini Massimiliano , Morellato Kavin , Graziani Gabriela , Baldini Nicola , Cauli Omar
Published: June 2022

Background: In clinical practice, specific customization is needed to address foot pathology, which must be disease and patient-specific. To date, the traditional methods for manufacturing custom functional Foot Orthoses (FO) are based on plaster casting and manual manufacturing, hence orthotic therapy depends entirely on the skills and expertise of individual practitioners. This makes the procedures difficult to standardize and replicate, as well as expensive, time-consuming and material-wasting, as well as difficult to standardize and replicate. 3D printing offers new perspectives in the development of patient-specific orthoses, as it permits addressing all the limitations of currently available technologies, but has been so far scarcely explored for the podiatric field, so many aspects remain unmet, especially for what regards customization, which requires the definition of a protocol that entails all stages from patient scanning to manufacturing. Methods: A feasibility study was carried out involving interdisciplinary cooperation between industrial engineers and podiatrists. To that end: (i) For patient-specific data acquisition, 3D scanning of the foot is compared to traditional casting. (ii) a modelling GD workflow is first created to design a process permitting easy creations of customized shapes, enabling the end user (the podiatrist) to interactively customize the orthoses. Then, (iii) a comparison is made between different printing materials, in order to reproduce the same mechanical behavior shown by standard orthoses. To do this, the mechanical properties of standard materials (Polycarbonate sheets), cut and hand-shaped, are compared with four groups of 3D printed samples: poly(ethylene glycol) (PETG), poly(acrylonitrile-butadiene.styrene) (ABS), polycarbonate (PC) and poly(lactic acid) (PLA) obtained by Fused Filament Fabrication (FFF). Results: Differences found between the foot plaster model obtained with the plaster slipper cast in a neutral position and the model of the real foot obtained with 3D scanning in the same position can be ascribed to the non-stationarity of the patient during the acquisition process, and were limited by a locking system with which no substantial differences in the almost entire sole of the foot scan were observed. Conclusions: Using the designed GD workflow, podiatrists with limited CAD skills can easily design and interactively customize foot orthoses to adapt them to the patients’ clinical needs. 3D printing enables the complex shape of the orthoses to be reproduced easily and quickly. Compared to Polycarbonate sheets (gold standard), all the printed materials were less deformable and reached lower yield stress for comparable deformation. No modifications in any of the materials as a result of printing process were observed.
A New Methodological Approach on the Characterization of Optimal Charging Rates at the Hydrogen Plasma Smelting Reduction Process Part 2: Results
Authors: Ernst Daniel , Zarl Michael Andreas , Cejka Julian , Schenk Johannes
Published: June 2022

To meet the target for anthropogenic greenhouse gas (GHG) reduction, the European steel industry is obliged to reduce its emissions. A possible pathway to reach this requirement is through developments of new technologies for a GHG-free steel production. One of these processes is the hydrogen plasma smelting reduction (HPSR) developed since 1992 at the Chair of Ferrous Metallurgy at the Montanuniversitaet Leoben in Austria. Based on the already available publication of the methodology in this work, potential process parameters were investigated that influence the reduction kinetics during continuous charging to improve the process further. Preliminary tests with different charging rates and plasma gas compositions were carried out to investigate the impacts on the individual steps of the reduction process. In the main experiments, the obtained parameters were used to determine the effect of the pre-reduction degree on the kinetics and the hydrogen conversion. Finally, the preliminary and main trials were statistically evaluated using the program MODDE® 13 Pro to identify the significant influences on reduction time, oxygen removal rate, and hydrogen conversion. High hydrogen utilization degrees could be achieved with high iron ore feeding rates and low hydrogen concentrations in the plasma gas composition. The subsequent low reduction degree and thus a high proportion of oxide melt leads to a high oxygen removal rate in the post-reduction phase and, consequently, short process times. Calculations of the reduction constant showed an average value of 1.13 × 10−5 kg oxygen/m2 s Pa, which is seven times higher than the value given in literature.
Phase Composition Effects on Dynamic Behavior and Strain Rate Sensitivity in Metastable β-Ti Alloys

Published: June 2022

In this study, high strain rate tension tests are conducted to determine and compare the dynamic mechanical behaviors and deformation mechanisms of different phase composition α-β metastable β-Ti alloys using a split Hopkinson tension bar. Two typical bimodal equiaxed αp + β and lamellar αs + β Ti-45551 alloy microstructures are formed through different hot working and thermal processing for investigating the effect of phase composition or microstructure on mechanical properties and strain rate sensitivity. It is demonstrated that dislocation nucleation and motion in the α/β phase and dislocation tangle or pile up at the α/β interface are typical deformation modes in both of the typical dual-phase Ti alloys at quasi-static loading conditions. Under dynamic loading, both the strength and ductility show a clearly positive strain rate dependence, which is directly related to dislocation activation in the α + β Ti-45551 alloy. Based on microstructure characterizations, it is shown that deformation twinning starts to become a major deformation mechanism in equiaxed αp + β microstructures under dynamic loading conditions. However, deformation twins are not favored in the lamellar αs + β Ti-45551 alloy due to its nano phase size. Finally, the mechanical behaviors and strain rate sensitivity are strongly dependent on the phase composition of metastable β-Ti alloys.

Published: June 2022

Three-dimensional direct laser writing technology enables one to print polymer microstructures whose size varies from a few hundred nanometers to a few millimeters. It has been shown that, by tuning the laser power during writing, one can adjust continuously the optical and elastic properties with the same base material. This process is referred to as gray-tone lithography. In this paper, we characterize by Brillouin light scattering the complex elastic constant C11 of different reticulated isotropic polymers, at longitudinal phonon frequencies of the order of 16 GHz. We estimate the real part of the C11 constant to vary from 7 to 11 GPa as a function of laser power, whereas its imaginary part varies between 0.25 and 0.6 GPa. The linear elastic properties are further measured at a fixed laser power as a function of temperature, from 20∘C to 80∘C. Overall, we show that our 3D printed samples have a good elastic quality with high Q factors only ten times smaller than fused silica at hypersonic frequencies.

Published: June 2022

The rock-breaking efficiency of a drilling tool directly affects the production costs and progress of foundation construction. It is essential to understand the mechanism of mechanical rock-breaking to improve rock-breaking efficiency. In this study, dynamic rock-breaking simulation research was carried out on a drill bit and was based on the LS-DYNA simulation platform. Additionally, the influence of the rotational speed of the spindle and the feed rate on the force of the drill bit in the rock-breaking process was obtained. The influence of the rotational speed of the spindle and the feed rate on drill vibration was also analyzed. The content of the presented theoretical and simulation research was verified through experiments. The following conclusions were drawn: first, the reaction force that rock has on the drill bit presents a law according to different rock types and drilling process parameters. With the increase in rotational speed, the axial reaction force decreases. With the increase in the feed rate, the axial reaction force increases. The effect of rock type on axial reaction force is nonlinear. Second, the influence of the spindle rotational speed and feed rate on the vibration of the drill bit also presents a law during rock-breaking. When the feed amount is constant, the transverse vibration slows down, and the axial vibration intensifies as the rotational speed increases. When the rotational speed is constant, as the feed increases, the transverse vibration slows down and the axial vibration intensifies. The research results provide a theoretical basis for selecting drilling process parameters and for improving rock-breaking efficiency.

Published: June 2022

Two new cladiellin-type diterpenoids (1 and 2) and four known related compounds 3–6, were isolated from the South China Sea soft coral Cladiella krempfi. Compound 2 is the third example of cladiellins of an unusual peroxy group in the C-6 position in C. krempfi. The structures and absolute configurations of the new compounds were established by extensive spectroscopic analysis, X-ray diffraction, and/or chemical correlation. In bioassay, all the compounds were evaluated for cytotoxicity and epidermal growth factor receptor (EGFR) inhibitory activity. A molecular docking experiment was conducted to study the structure–activity relationship of cladiellin-type diterpenoids on EGFR inhibitory activity.
Long-term study of the Sword-leaved Helleborine Cephalanthera longifolia (Orchidaceae) in Knapdale, Argyll
Authors: Batty Patricia
Published: June 2022

The results of detailed monitoring of four populations of Sword-leaved Helleborine, Cephalanthera longifolia (L.) Fritsch over a 22-year period at Knapdale, Argyll are presented. Flowering and vegetative plants were recorded each year, with individuals relocated using triangulation. There were marked differences in the population changes at the four sites with the likely causes being grazing and changes in light intensity. In addition, a few large plants were recorded over a 31-year period. A few, large, plants flowered for the majority of the study and were probably of disproportionate importance to the long-term survival of the plant at Knapdale. The flowering, survival and occurrence of the other plants varied considerably. In addition, observations from other sites in Knapdale were noted.

Published: June 2022

Tomando en cuenta que la investigación de los productos ecológicos alimenticios es de suma importancia, este estudio se enfoca en el análisis de la carne de granja que se comercializa en las carnicerías de la ciudad de Machala. Para analizar esto se ha implementado un modelo teórico sustentado en la Teoría de los Valores del Consumidor. Se utilizó una metodología con enfoque cuantitativo, un muestreo no probabilístico de 312 encuestados que fueron analizados con la técnica SEM-PLS. Los resultados indicaron que solo los valores responsabilidad del valor social, valor condicional y valor condicional de calidad tienen un efecto positivo y significativo en comportamiento de elección del consumidor; mientras que el valor funcional de precio, valor emocional e identidad de valor social no logran tener un efecto estadísticamente significativo. Estos resultados se deben al hecho que la carne todavía no está percibida totalmente como un producto ecológico.

Stock Price Synchronicity, Earnings Quality, Foreign Ownership: Evidence of ASX200 Firms
Authors: Yuwono Jessie D. , Martowidjojo Yanthi Hutagaol
Published: June 2022

The issue of stock price synchronicity has been a debate for more than a decade. The question is central to what information that is more reflected in market stock price. One stream suggests that firm-specific information is, relatively, more reflected in its stock price, while the other streams argues that market (industry)-specific information is more relevant in stock price formation (Zhou, 2007). Studies about stock price synchronicity have been ubiquitous in emerging markets (e.g. Gul et al., 2010; Li et al., 2020; Vo & Chu, 2019; Farooq & Aktaruzzaman, 2016; Lyimo, 2014). Price synchronicity studies are also found in mature markets but majorly in US (e.g. Zhou, 2007; Gul et al., 2011; Kan & Gong, 2018). To the author knowledge, the only study of stock price synchronicity in Australia is by Bissessur & Hodgson (2012) that investigate the impact of IFRS adoption. Generally, prior studies found that IFRS implementation increases financial reporting quality. Specifically, this study focuses on the relationship between earnings quality and price synchronicity, since earnings is the mostly accounting information used by investors to price the stocks in the market.

Entrepreneurial Engagement of the Tertiary Education Subsidy (TES) Grantees in Central Philippines State University
Authors: Lycel L. Pacheco , Cristyflor M. Escordial , Aladino Moraca
Published: June 2022

The Unified Student Financial Assistance System for Tertiary Education or UniFAST is the government agency in charge of implementing the Universal Access to Quality Tertiratry Education Act (RA 10931). The UniFAST was created in 2015 by virtue of RA 10687 as a system to unify existing government student financial assistance programs for Tertiary Education in the Philippines. It will ensure that deserving Filipinos are given equitable access to educational opportunities. One of these, the Tertiary Education Subsidy or TES. Subsidy as a form of financial assistance plays an important role to augment financial incapacities of students enrolled in Higher Education Institutions or HEIs (Avery, 2014). Through RA 10931 which was passed into law on August 3, 2017, the citizens were allowed full access to quality education by providing adequate funding and increasing participation rate in the tertiary education. This further gives chances to the poor but deserving students to reach their goals and finish a degree. The Implementing Rules and regulations (IRR) of this law recognizes the complementary roles of public and private Higher Educations Institutions and Technical-Vocational Institutions in the tertiary education system, and the invaluable contribution of private tertiary institutions to the education system. As been embedded in our Philippine Constitution, the quality education is an inalienable right of all Filipinos and it is the policy of the State to protect and promote the rights of students to quality education at all levels.

Dry Socket in Smokers after Odontectomy
Authors: Poluan Christian F. , Anindita Pritartha S. , Mintjelungan Christy N.
Published: June 2022

Abstract: Dry socket is delayed healing of a socket resulted from extraction due to the release of blood clot leaving visible bone surface. There are several risk factors of dry socket such as dentistry skills, perioperative infection, gender, extraction site, use of oral contraceptives, smoking, use of local anesthetics with vasoconstrictors, and position of impacted third molars. The risk of dry socket in smokers is greater than in non-smokers. This study aimed to obtain the occurrence of dry socket in smokers after odontectomy. This was a literature review study using databases of Google Scholar, PubMed, and Clinical Key. The results obtained 10 articles that were relevant to the topic of discussion. The incidence of dry socket was higher in smokers than in non-smokers. The high incidence of dry socket in smokers was influenced by the ingredients contained in cigarettes, among others, nicotine, carbon monoxide, and hydrogen cyanide. Nicotine affected the rate of epithelialization and blood flow, carbon monoxide caused a decrease in oxygen levels, and hydrogen cyanide could damage the metabolism of cellular respiration. These were related to the phase of wound healing at the stage of inflammation and epithelialization of fibroplasia. In conclusion, the incidence of dry socket after odontectomy is more common in smokers than in non-smokers.Keywords: dry socket; smoking; odontectomy Abstrak: Dry socket merupakan keadaan penyembuhan soket bekas pencabutan yang tertunda karena lepasnya bekuan darah sehingga permukaan tulang terlihat.

SUPERVISION OF SCHOOL SUPERVISORS BASED ON SPIRITUAL APPROACH (An Initial Draft)
Authors: Jamaluddin Jamaluddin
Published: June 2022

Madrasas are Islamic educational institutions that have a major role in developing Islamic education that is growing. This of course cannot be separated from the role of the government which regulates its governance, including by implementing supervision of its implementation as an effort to improve the quality of learning. School/madrasah supervisors have an important role in providing enlightenment and directing schools/madrasas so that they can run optimally. The purpose of this study is to design and develop a model for supervising school supervisors based on a spiritual approach so that the role of supervision is not only oriented to the right or wrong of a job but as a companion who can guide schools/madrasahs towards improvement in instructional based on a spiritual approach.In the data collection process, library research methods were used and data collection was taken from the theory of educational supervision and Islamic teaching sources in order to obtain a spiritual-based supervision model that could be implemented in the supervisory activities of school/madrasah supervisors. The draft that has been compiled is then discussed involving experts consisting of lecturers and school/madrasah supervisors who are distributed via google form. The results of this study indicate that the supervisory model of school/madrasah supervisors based on a spiritual approach consists of: 1) supervisory duties as a mandate from Allah swt, 2) supervisor duties as a charity, 3) supervisor duties as the obligations of knowledgeable and knowledgeable people, 4) supervisor duties as the recipient of the baton of the struggle of the Prophet Muhammad.

Objectives: The purpose of the present retrospective cross-sectional study was to identify the etiologies, clinical and radiological aspects of symptomatic unilateral maxillary sinusitis requiring hospitalization and to discuss surgical treatment indications. Material and methods: The medical records of 115 patients suffering from symptomatic unilateral maxillary sinusitis (SULMS) between 2010 and 2019, were examined. A total of 46 patients were selected by collecting data from the patients' medical records. Results: The aetiology of SULMS was in 23.9% of cases of dental origin and in 76.1% of cases of rhinogenic origin. Rhinological signs were predominant, dominated by nasal obstruction (56.52%) and headache (52.17%). The computerized tomography (CT) scan showed diffuse sinus opacity without fluid level in 43.5% of cases. The surgery indication was in 41.3% of cases due to medical treatment failure and to the presence of intra-sinusal foreign body in 10.9% of cases. Conclusions: The results of this study indicate that general state of health, age, sex, sinusitis etiology, middle meatus obstruction and local anatomical factors do not appear to be factors influencing management compared to the chronic evolution of sinusitis (P=0.03). This study has shed light on dental infectious foci involvement in both the initiation and flare up of unilateral maxillary sinusitis.

Osteoma of the jaw bones is a rare entity with very few cases reported in the literature. Osteomas are benign, slow growing osteogenic tumors of the bone commonly encountered in the craniofacial skeleton and characterised by the proliferation of compact or cancellous bone. They can be central, peripheral or extra-skeletal in their location .The solitary periosteal osteomas of the jaw bones are quite rare. The mandible is more commonly affected than the maxilla, with the sites of predilection being the lingual aspect of the body, the angle and the inferior border. The diagnosis is based on the clinic, the radiological examinations. The CT scan is the best imaging modality as it provides exact details about the site, dimensions and extension of the lesion. Additional three-dimensional CT imaging helps planning the surgery. Confirmation of the diagnosis is pathological. Surgical management should be indicated both for cosmetic complaints and for diagnostic confirmation, especially in bulky lesions. We report a case of a Peripheral Giant Osteoma of Mandible in a 60-year-old man.

Hepatocellular carcinoma (HCC) constitutes 70-85% of all primary liver tumors and ranks as the fifth most common cancer and the second most common cause of cancer deaths worldwide [1, 2]. Steatohepatitic hepatocellular carcinoma (SH-HCC) is a variant of hepatocellular carcinoma (HCC) with established association with nonalcoholic steatohepatitis (NASH), while its association with alcoholic steatohepatitis (ASH) is unclear. The steatohepatitic variant of HCC (SH-HCC) typically presents in patients with metabolic risk factors and either cirrhotic or non-cirrhotic NAFLD and shares many of the histological features found in non-alcoholic steatohepatitis (NASH). It accounts for 5-20% of HCCs, and the background liver may show steatohepatitis [3, 4]. We present a case of a 53-year-old deceased male. Part of liver was received after autopsy, which appeared nodular grossly and histopathological diagnosis of Steatohepatitic variant of Hepatocellular Carcinoma was made.

A local bentonite clay from Maghnia (Algeria) was activated with chemical method characterized and tested for its ability to adsorb Zinc (II) from refinery wastewater. Batch experiments were conducted to study the effects of the main parameters such as contact time, initial metal concentration and agitation speed on the adsorption of Zn (II) by local bentonite clay. Experiences have led to the following results: an adsorption rate of the order of 98 % with operating conditions of pH = 4.5, agitation speed of 400 rpm and temperature of 25 ºC. Pseudo-first-order, pseudo-second-order and intraparticle diffusion models were used to analyze the kinetic data obtained at different concentrations. The pseudo-second-order kinetic model agrees very well with the experimental results. In order to determine the best-fit isotherm, in the studied concentration range of Zn(II) at 25 ºC, the experimental equilibrium data were analyzed using tow adsorption isotherm models: Langmuir and Freundlich models, these two models give a good fit.
