Design and characterization of a hyperbolic-elliptical lens pair in a rapid beam steering system for THz spectral imaging of the cornea
Authors: Virk Arjun , Harris Zachery , Arbab M. Hassan
Published: July 2023

Terahertz (THz) time-domain spectroscopy has been investigated for assessment of the hydration levels in the cornea, and changes in corneal topography and the intraocular pressure. Previous efforts at THz imaging of the cornea have employed off-axis parabolic mirrors to achieve normal incidence along the spherical surface. However, this comes at the cost of an asymmetric field-of-view (FOV) and a long scan time because it requires raster-scanning the collimated beam across the large mirror diameter. In this paper, we propose a solution by designing a pair of aspheric lenses that can provide a larger symmetric spherical FOV (9.6 mm) and reduce the scan time by two orders of magnitude using a novel beam-steering approach. Using Nelder-Mead optimization, a hyperbolic-elliptical lens was designed to achieve normal incidence and phase-front matching between the focused THz beam and the target curvature. The lenses were machined from a slab of high-density polyethylene and characterized in comparison to ray-tracing simulations by imaging several targets of similar sizes to the cornea. Our experimental results showed excellent agreement in the increased symmetric FOV and confirmed the reduction in scan time to about 3-4 seconds. In the future, this lens design process can be extended for imaging the sclera of the eye and other curved biological surfaces, such as nose and fingers.
Valuating the capital structure under incomplete information
Authors: Meng Ren Dong , Chen Yunmin , Maynard Alex , Pysarenko Sergiy
Published: July 2023

Can higher uncertainty increase the valuation (market-to-book value) of young firms compared to more established ones? As the current market shows higher levels of uncertainty about companies’ expected cash flows and changes in firm value, the question of the fundamental convex relationship between the two becomes more relevant. This paper aims to study how cash flow uncertainty affects the capital structure/leverage of a firm over time. A simple Bayesian learning framework is employed to assess leverage ratios in the presence of parameter uncertainty about expected cash flow. This study provides an analytical solution for leverage as a function of firm age and explores the implications using numerical results. The model links market leverage with expected cash flow volatility and firm age. Young firms face uncertainty about their expected cash flows and hence their firm value. Managers continuously update their evaluation of leverage ratios when they observe realized cash flow until firms reach maturity. Therefore, the paper provides a novel explanation of why the leverage ratio for many start-ups increases over time: the resolution of uncertainty decreases upside shock expectations as the firm ages. This result is useful both for academics, who can test the formulas derived in this paper for various industries, countries, and conditions, and for practitioners, who can use them to calibrate algorithmic trading models when linking uncertainty and firm valuation.

Purpose of the study. From 2018 to 2024 on the territory of the Russian Federation there are national projects in key areas of social policy. In 2025, it is planned to sum up the results of the implementation of these national projects. The presented study focuses on the intermediate results of the national project implementation “Demography”.The purpose of the study is to assess the effectiveness of the national project implementation “Demography” in the Volga Federal District as of 2021.Materials and methods. The methodological basis of the study was the non-parametric method for evaluating the effectiveness of Data Envelopment Analysis (DEA). An input-oriented model was used to increase the inputs without changing the outputs. The target index for the implementation of the national project - the total birth rate - was used as a performance index. Indexes-factors are selected taking into account the possibility of a potential impact on fertility. Among them: general marriage rates; the level of employment of the population of working age; real monetary income of the population; consumer spending on average per capita per month; the number of families who received housing, premises and improved their living conditions during the year.The information base of the study is the data of the Federal State Statistics Service.Results. The regions of the Volga Federal District that are effective and inefficient in terms of achieving the target index for the implementation of the national project “Demography” are identified and their typology is carried out. The group of leading regions close to the implementation of the national project in full includes the Republic of Mari El, the Udmurt Republic and the Orenburg region. They act as benchmarks for other regions of the district in achieving the planned target index for the national project implementation. The group of “hybrid regions”, which includes seven entities, has the ability to ensure the execution of the national project by the end of its implementation period. Four “outsider regions” have the main problems in achieving the targets of the national project “Demography”, including the Republic of Mordovia, with an efficiency coefficient value of 0,742.

Published: July 2023

Background:

Monkeypox is a global public health issue caused by the
monkeypox virus (MPXV). As of October 28, 2022, a total of 77,115 laboratoryconfirmed
cases and 3,610 probable cases, including 36 deaths, were reported, with
9,070 cases reported in Brazil, the second most affected country. The need to develop
national technologies for the rapid diagnosis of emerging diseases for mass testing of
the population is evident, as observed in the SARS-CoV-2 pandemic.

Objective:

With that in mind, this article provides an overview of current methods,
techniques, and their applications in the molecular detection of monkeypox, focusing the
search on real-time polymerase chain reaction (qPCR), polymerase chain reaction
(PCR), and polymerase chain reaction-enzyme linked immunosorbent assay (PCRELISA).

Methods:

The relevant documents or papers covered in this study were selected by a
search in international bibliographic databases. The search terms used in the databases
were aimed at summarizing existing knowledge on molecular diagnostic methods, such
as monkeypox; MPX, MPXV, qPCR, PCR, PCR-ELISA, diagnosis and detection
searched separately or together using the Boolean operator “AND” either in the title or
abstract. The searches took place in September 2022, and the corresponding articles
were selected between 2012 and 2022.

Results:

We found 256 documents in total and twelve studies addressing the molecular
diagnosis of monkeypox were classified as possible sources for this review.

Conclusion:

It is evident there is a pressing need to develop national technologies for
rapid diagnosis of emerging diseases for mass testing of the population. It is also
extremely important to have national detection kits with greater diagnostic capacity to
assist in developing effective public policies in countries affected by this disease.

Published: July 2023

Tissue engineering and regenerative medicine have received significant attention in treating
degenerative disorders and presented unique opportunities for researchers. The latest research on tissue
engineering and regenerative medicine to reconstruct the alveolar cleft has been reviewed in this study.
Three approaches have been used to reconstruct alveolar cleft: Studies that used only stem cells or biomaterials
and studies that reconstructed alveolar defects by tissue engineering using a combination of
stem cells and biomaterials. Stem cells, biomaterials, and tissue-engineered constructs have shown promising
results in the reconstruction of alveolar defects. However, some contrary issues, including stem cell
durability and scaffold stability, were also observed. It seems that more prospective and comprehensive
studies should be conducted to fully clarify the exact dimensions of the stem cells and tissue engineering
reconstruction method in the therapy of alveolar cleft.

Fuel Consumption Efficiency Enhancement of Synchronous Diesel Generator Operating at Adjustable Speed using Adaptive Inertia Weight Particle Swarm Optimization Algorithm
Authors: Muhtadi M Zaky Zaim , Suryoatmojo Heri , Soedibyo Soedibyo , Ashari Mochamad
Published: July 2023

Diesel generator is a reliable source of electricity, but requires quite high operational costs, especially for fuel. This paper describes a technique for reducing fuel consumption in Diesel Engine Synchronous Generator systems. The system is originally a Constant Speed Diesel Synchronous Generator (CSD-SG), but during certain conditions, the speed is reduced to minimize fuel consumption by adjusting the Specific Fuel Consumption (SFC) map. SFC is defined as the amount of fuel consumed by a diesel engine generator for each unit of power output. It shows various numbers depending on the speed and operating power. In this paper, we use the Adaptive Inertia Weight Particle Swarm Optimization (AIWPSO) algorithm to select of the proper SFC curve at a certain speed and operating power. AIWPSO employs an adaptive inertial weight adjustment method, which enables this algorithm to achieve faster convergence than conventional Particle Swarm Optimisation (PSO) algorithms. The system is embedded with AC/DC/AC power electronics converter to regulate the frequency. Data set of 1000 kVA Cummins diesel engine generator from the oil and gas company in Central Java, Indonesia was taken for simulations. The results show that the AIWPSO algorithm calculates the fuel consumption as 1,678 liters per day on a typical condition, whereas the previous method, the linear line needs 1,693 liters per day. Therefore, using AIWPSO method can save up to 450 liters of fuel per month. The simulation results show that the proposed method can improve fuel efficiency compared to the previous model.

Published: July 2023

Karet ebonit mempunyai keunggulan karena sifat mekanik yang tinggi, kaku, dan keras namun cenderung mudah getas. Penambahan filler clay yang mengandung bentonit dinilai dapat mengurangi sifat getas karet ebonit. Studi ini mencoba membuat karet ebonit berbasis karet alam dengan variasi bentonit sebagai filler 0, 2, 4, 6, 8, 10 phr yang dicampur sebagai masterbatch karet alam yang menggunakan surfaktan kationik, dengan karet alam jenis RSS 1, belerang 30 phr dan bahan aditif lain dengan waktu 90 menit dan suhu vulkanisasi 1600C. Uji sifat rheologi menunjukkan semakin bertambahnya masterbatch yang mengandung bentonit dan dan surfaktan kationik ditambahkan akan memberikan pelunakan pada komposit. Hasil pengujian kekerasan menunjukkan kenaikan dengan bertambahnya bentonit yang digunakan. Pengujian kuat tarik komposit b4 (4 phr bentonit) menghasilkan nilai tertinggi 41,3 N/mm2 dan modulus young 362,77 N/mm2. Hasil uji SEM menunjukkan permukaan lebih halus pada b4 dengan terbentuk agregat yang sangat kecil dibanding dengan b10 yang cenderung lebih besar ukuran agregat. komposit b4 mengindikasikan filler terdistribusi baik karena ukuran agregat kecil sehingga memberikan pengaruh terhadap kekuatan mekanik lebih tinggi dibanding dengan komposit b10 dengan agregat besar yang cenderung terjadi aglomerasi sehingga filler tidak terdistribusi dengan baik.

MINI REVIEW HIDROGENASI KARET ALAM
Authors: Winarto Dody andi , Chalid Mochamad , Liza Chandra , Fathurrohman Mochamad Irfan
Published: July 2023

Karet alam merupakan komoditas penting yang berperan sebagai bahan baku untuk berbagai aplikasi yang membutuhkan kekuatan tarik yang tinggi, fleksibilitas, daya rekat, ketahanan terhadap suhu rendah, ketahanan kikis, dan ketahanan terhadap air. Namun karet alam murni mempunyai kelemahan karena mengandung ikatan rangkap dua (C=C) yang menjadikan karet alam mempunyai ketahanan yang kurang baik terhadap oksidasi, panas, ozon dan lingkungan. Modifikasi karet alam berpotensi untuk menanggulangi masalah tersebut. Hidrogenasi merupakan modifikasi kimia untuk mengurangi ikatan rangkap dua tersebut yang dapat dilakukan dengan penambahan hidrogen. Proses hidrogenasi dilakukan dengan menggunakan katalis dan dapat dilakukan dengan donor hidrogen yaitu senyawa diimida pada kondisi yang relatif ramah. Keberhasilan hidrogenasi diukur dengan derajat hidrogenasi melalui beberapa metode. Dari penelusuran yang dilakukan, karet alam terhidrogenasi mempunyai prospek yang baik untuk diterapkan, namun hingga saat ini belum ada industrialisasi yang masif dalam memproduksinya.

Authors: Gomes Neto Manoel Bastos , Silva Lucas Emmanuel Nascimento , Grangeiro Rebeca da Rocha
Published: July 2023

This paper aims to systematically summarize the literature available on gender and consumer research to evaluate its foundations and the state of the art of those studies. To do so, a literature review was conducted using the Scopus database and applying bibliometric and content analysis. The database of this study consisted of 1001 articles and reviews, written by 2759 authors and coauthors, and published in 471 journals. The most cited paper is “Poststructuralist Lifestyle Analysis: Conceptualizing the Social Patterning of Consumption In Postmodernity” (Holt, 1997) and the journal that publishes most papers on this topic is Journal of Consumer Marketing. The United States has the biggest number of papers. The content analysis of the most cited papers showed a predominance of quantitative studies. Despite the growing interest in the topic, researchers are still focusing on gender as an independent variable and not as a category os analysis., therefore, it is necessary to understand the complexity and particularities of this phenomenon. Consumer researchers need to focus on gender in a more broad perspective, investigating how marketplaces practices help to create gendered environments that help to perpetuate gender disparities. We discussed further new directions for future research and challenges that the COVID-19 pandemic brought to consumer’s life regarding gender and that need to be addressed in the future.

Published: July 2023

Objetivo: este trabalho teve por objetivo analisar a capacidade da cadeia brasileira de embalagens em promover a criação de circuitos (loop), a virtualização e a troca entre os participantes.
Método: esta pesquisa é considerada qualitativa, aplicada e descritiva. O estudo de caso coletou dados por meio de pesquisa documental e entrevistas em profundidade com roteiro semiestruturado. 53 (cinquenta e três) stakeholders da cadeia de embalagens foram entrevistados, entre eles, promotores de justiça, políticos, empresários, catadores, especialistas, servidores públicos e representantes de organizações não governamentais. Para análise dos dados empregou-se a análise de conteúdo do tipo categorial temática.
Resultados: a insistência dos fabricantes em utilizar materiais que não possuem comercialização no mercado da reciclagem ilustra a problemática quanto ao Loop. Ainda que a pandemia da COVID-19 tenha acelerado práticas de Virtualização, como “digitalização de atividades e processos” e “melhoria do produto e manutenção periódica”, a maioria dos entrevistados afirma não existir ou não perceber feitos no cenário brasileiro. Apesar de algumas empresas se mostrarem preocupadas com tecnologias, o cenário 4.0 com big data ou machine learning está distante de ser realidade no Brasil.
Considerações finais: o presente estudo traz contribuições teóricas e práticas que podem ser extraídas a partir dos resultados desta pesquisa. Espera-se que estas constatações sirvam de diretrizes no processo de tomada de decisão no sistema de logística reversa de embalagens. Aos acadêmicos, demonstra-se a aplicação de um framework já consolidado na área para investigação de práticas socioambientais, além de instigar lacunas deixadas para pesquisas posteriores.

Experimental assessment of packaging paper properties effect in combination with storage conditions on the adhesion performance of automotive glass
Authors: Kordová T. , Mareška A. , Havlík Míka M.
Published: July 2023

The aim of this work was an experimental comparison of different types of packaging paper, determining the effect of packaging material properties in combination with storage conditions on the purity of glass surface and the related quality of adhesion of bonded materials. In the automotive industry, the quality of adhesion is a key factor, as automotive glass must meet the safety requirements. During the experiments, the glass sheets were wrapped in four types of paper and stored according to the conditions that are common in a real production. The research was focused on the influence of different composition of packaging papers on the resulting adhesive properties of glass sheets. According to the results obtained in this work, it can be stated that during the storage there is an interaction between paper and glass. According to XRF analyzes, ongoing corrosion of the glass can be inferred. The resulting adhesion was assessed based on a peel test, which took place under defined conditions given by standard customer specifications. It has been observed that the negative effect of unsuitable paper increases over time. For optimal adhesion it is necessary to emphasize the packaging materials and the storage conditions of the glass. The results and knowledge achieved in this work can significantly improve the quality of production in which a material is glued to the glass surface.

Background: Cardiopulmonary resuscitation (CPR) is a lifesaving procedure performed by qualified rescuers. The quality of CPR depends on effective chest compression (CC) characteristics: rate, depth, hand position, and chest recoil. Besides CC, previous research has proven that physical activity level (PAL) varies among rescuers and affects CPR quality. This study aims to assess the association between PAL and the quality of continuous chest compressions-cardiopulmonary resuscitation (CCC-CPR) for 5 minutes by qualified rescuers at the National Guard Hospital in Jeddah (NGHA-J).
Methods: This is a cross-sectional study. The global physical activity questionnaire was used to measure the participants' PALs, and the SimMan 3G mannequin was used to measure the four CC characteristics. The recommended sample size is 45 of the rescuers at NGHA-J.
Results: A total of 45 members were involved in the study, and most participants were 27 (60%) males. Most participants are classified as having high PAL 21(46.67%). The study indicates that there is no significant effect among the PALs and the CCC-CPR effectiveness according to (p 0.65) which is determined by the non-parametric Kruskal Wallis test. The optimal effective CCs between the three groups of PALs were achieved by the moderate PAL participants with a median of 47.5 (IQR 35).
Conclusion: The study findings deny any relationship between the quality of the CCC-CPR and the PAL of the rescuers.

Engineering Design Of Fuel Reactor Pirolysis Incinerator (IPFR) Processing Plastic Waste into alternative Fuel with Residual Oil Heating
Authors: Wahyu pratama Aditya
Published: July 2023

In Indonesia, plastic waste has become an important problem at this time, because it causes environmental pollution problems. With this, further action is needed regarding the treatment of waste utilization, one of which is by converting waste into liquid fuel. Some types of rubbish that we often encounter are plastic bottles such as plastic cups, plastic bottle caps, children's toys and margarines and others, which is one of the types of PP (polypropylene) waste. The development of current plastic waste treatment technology is to convert plastic waste into fuel oil by utilizing plastic waste to be processed as plastic fuels such as premium fuel, diesel and kerosene. Polypropylene type plastic is the type of plastic that is most widely used in daily life because it has good mechanical properties with low density, heat and moisture resistance, and has good dimensional stability. Some of the technology used to convert plastic waste, among others, by using the method of high temperature (Thermal Cracking). In this study, researchers designed a Thermal cracking device, namely an Incinerator, a plastic waste smelter with high temperature, where the modification of this tool is to use used fuel oil or residual oil. In this study, the researcher analyzed the burning time, the amount of waste mass needed for the melting process in the Incinerator. In this research, a fuel equivalent of 1.5 liters of premium fuel was produced with 10 kg of plastic waste burned in the incinerator with a burning time of 125 minutes of the pyrolysis process, with a combustion temperature of 180-250 degrees Celsius.

Sedimentation is a crucial factor when it comes to river problems. Sediment can cause silting of the river so that its capacity be reduced and can cause overflow of water to the surface. Every year, Districts of Nanga Mahap at Sekadau Regency always experiences flooding and the problem is still happening up until now. One of the causes of the occurrence of flooding in Nanga Mahap District is the overflow of the Mahap River. This study aims to determine the characteristics and rates of bottom sediment transport rate in the downstream of the Mahap River. Sediment collection was carried out on 8 segments of the estuary. In the study, laboratory tests were carried out regarding specific gravity and grain size of sediment particles refers to the texture classification by USDA (U.S. Department of Agriculture) and freight rate calculations Basic Sediment with Duboys Method. Based on characteristic analysis Mahap River sediments obtained the average D50 sediment grain diameter value from all research points that is equal to 1.63 mm, the results of testing the specific gravity the average obtained is 2.754 gr/cm3 so that it can be classified in the form of coarse grains with a type of sand sediment. The largest base sediment transport rate of bed load occurred at point 2 of 8.816 tons/day and the smallest was at point 7, which is 0.154 tons/day. From the calculation, result shows that if the velocity of falling particles is greater than the velocity of the flow of river water, therefor the sediment particles will settle.

This study discusses the effect of the addition of resin fibers (Dicranopteris linearis) on the characteristics of concrete. The purpose of fibers to the characteristics of concrete. horns, anti-termite, not easily broken and resistant to humid air and is a plant that grows a lot in Pagar Alam City area. Therefore, the researchers decided to examine the effect of adding resin rod fibers to the characteristics of concrete. characteristics of this concrete is an experimental method that is tested, namely the physical material test, slump test, compressive and flexural strength of concrete. Experiments with the addition of resin rod fibers to the concrete mix of 0.5% of the weight of normal concrete cement. All samples were tested at the age of 3,7,14,21 and 28 days. Based on the test results, 3 cm and 5 cm long resin fibers were used. At 3 cm compressive strength of 28 day old concrete decreased by 0.36% from normal concrete with flexural strength increased by 0.02% of normal concrete while at 5 cm compressive strength of 28 day old concrete decreased by 0.66% of concrete normal while the flexural increase as much as 0.04% of normal concrete. The decrease in compressive strength is due to the addition of impregnated fibers into the concrete which will create more voids or voids in the concrete, the reduced density of concrete and disruption of the bond between cement and other concrete aggregates and the increase in flexural strength is caused because the resin fibers play a role in resisting cracks due to the pressure exerted by them. occurs in the concrete so as to increase the flexural strength of the concrete.

Supadio International Airport in Pontianak is a gateway for many domestic and international tourists. In order to boost West Kalimantan's economy and tourism, PT. Angkasa Pura II (Persero) wants to expand the Supadio International Airport by adding a second runway. This article looks at how the FAA (Federal Aviation Administration) method was used to plan the thickness of the rigid pavement on the new runway at Supadio International Airport. The expected number of people and aircraft will be calculated using the double-moving average method. The anticipated time frame is 2035, with 12.763.479 passengers and 121.782 aircraft movements annually. The Airbus A330-300 requires the most considerable thickness of the concrete slab, consisting of dual tandem wheel types and a maximum take-off weight (MTOW) of 533.519 lbs. As the original soil is in poor condition, a 52.5-cm-thick embankment is required to achieve a CBR value of 6%. The rigid pavement thickness design result for the design life of 2035 is as follows: surface course = 56,39 cm, subbase course = 15,24 cm, stabilized subgrade/base soil = 52,5 cm for critical areas, and a surface course of 50,751 cm, subbase course = 13,716 cm, and stabilized subgrade/base soil = 52,5 cm for non-critical soil.

To support in-line quality control of raw milk, we propose a fiber-optic spatially-resolved spectroscopy (SRS) setup. This setup allows to vary the interaction of long-wave near-infrared (LW-NIR) light with the milk by submerging a separate optical illumination and detection fiber into the sample and altering their relative distance to optimize measurements for specific milk component(s). We evaluated this approach for predicting milk fat, protein, and lactose content and determined the optimal illumination-to-detection distances for each milk component. The region between 1.1 to 1.8 mm was optimal for lactose, and between 2.2 and 3.8 mm for fat and protein. These distance ranges resulted in a root-mean-square error of prediction (RMSEP) of less than 0.10% weight/weight (wt/wt) for milk fat, and lower than 0.13% (wt/wt) for protein and lactose. Integration of these distances into a fiber-optic SRS reflectance probe would allow to simultaneously determine the fat, protein, and lactose content of raw milk in-line with high accuracy.
