Two-photon fluorescence-assisted laser ablation of non-planar metal surfaces: fabrication of optical apertures on tapered fibers for optical neural interfaces
Authors: Balena Antonio , Bianco Marco , Pisano Filippo , Pisanello Marco , Sileo Leonardo , Sabatini Bernardo L. , Vittorio Massimo De , Pisanello Ferruccio
Published: June 2020

We propose a feedback-assisted direct laser writing method to perform laser ablation of fiber optic devices in which their light-collection signal is used to optimize their properties. A femtosecond-pulsed laser beam is used to ablate a metal coating deposited around a tapered optical fiber, employed to show the suitability of the approach to pattern devices with a small radius of curvature. During processing, the same pulses generate two-photon fluorescence in the surrounding environment and the signal is monitored to identify different patterning regimes over time through spectral analysis. The employed fs beam mostly interacts with the metal coating, leaving almost intact the underlying silica and enabling fluorescence to couple with a specific subset of guided modes, as verified by far-field analysis. Although the method is described here for tapered optical fibers used to obtain efficient light collection in the field of optical neural interfaces, it can be easily extended to other waveguide-based devices and represents a general approach to support the implementation of a closed-loop laser ablation system of fiber optics.

Eficácia do mito no domínio ético-político
Authors: Maia Rosane De Almeida , Cornelli Gabriele
Published: June 2020

se com uma breve reflexão sobre o mito e o papel que tem exercido na filosofia desde a antiguidade grega clássica. Partimos da consideração de sua relevância na obra de Platão, em que emerge como narrativa vigorosa e persuasiva e, por vezes, indissociável do logos enquanto recurso de suasão na polis. É primordial nos ater no conhecido mito da caverna. A despeito da indiscutivelmente ampla e profunda investigação já procedida por inúmeros intérpretes na história exegética do diálogo A República, consideramos que há um veio inesgotável a ser explorado, diante dos desafios permanentemente recolocados por este instigante mito platônico. Buscamos nele riquezas oriundas de uma leitura escatológica do mito, apontando para a descida ao mundo dos mortos – catábase – como um itinerário místico-filosófico e para a efetividade da mensagem política contida no diálogo. Explicitamos que aqui se leva em conta a Atenas dos séculos V e IV a.C., com sua religiosidade, cultura e instituições políticas,  uma vez que se considera que a contextualização da narrativa no seu ambiente histórico-cultural, tanto como o entendimento de sua forma literária, são imprescindíveis para se vislumbrar sentidos e apreender, de forma rigorosa, sua singularidade. Nessa abordagem metodológica, a influência da tradição Órfico-Pitagórica nos faculta retomar o pensamento platônico, notadamente na sua dimensão ética, em que a concepção sobre imortalidade da alma configura uma certa representação da vida e da morte.

A conduta direcionada a intervenções focadas na redução dos desperdícios nas operações da manufatura e serviços são ações precedentes e imperativas que todo gestor de processos deve buscar constantemente. A diminuição das perdas e desperdícios com consequente aumento da eficiência produtiva se configuram como um dos grandes objetivos das organizações e seus stakeholders. Atualmente, várias técnicas e ferramentas para a redução de desperdícios podem ser empregadas, porém, neste trabalho, será utilizado o conceito do nivelamento do fluxo produtivo, que pode ser alcançado por meio do balanceamento de operações. Portanto, o objetivo do presente trabalho é aplicar a simulação computacional como complemento ao método do balanceamento de operações, reduzindo o número de operadores da linha de montagem e suas ociosidades em um processo fabril real. Como método de pesquisa empregou-se o estudo de caso com a utilização de informações e dados reais, coletadas por meio de uma investigação, de oito meses, realizada na empresa. Por conseguinte, pode-se afirmar que o projeto de balanceamento de operações aplicado na linha de montagem foi eficaz, porquanto uma redução da ociosidade geral para um valor próximo a 4% foi constatada, conforme relatório da simulação computacional.
Bioreceptivity of different painting systems to mould growth on "tabique" walls and plasterboards
Authors: Almeida Ricardo M.S.F. , Barreira Eva , Silva Elisabete , Brás Isabel , Rocha Ana
Published: June 2020

Mould growth on the inner surfaces of building elements is a common pathology found in buildings, resulting not only in the early degradation of the materials but also in the deterioration of the indoor environment. On the other hand, building renovation provides an exceptional opportunity to improve the quality of life of its users. Within this scope it is therefore relevant to understand the effect that different painting solutions may have on mould growth. This work evaluated the mould growth in four kinds of substrates, with different painting systems. The selected case studies were: two "tabique" walls (constructive solution with strong implantation in the built heritage), one with lime mortar and another with lime and cement mortar; and two gypsum plasterboards (a constructive solution that is widely applied in building renovation), a normal and a water repellent. To evaluate the mould growth, two methodologies were adopted: counting the number of colony forming units (CFU) in six sampling periods; and visual inspection through photographic recording, including the quantification of the percentage of "dark pixels". At the end of the test it was established that plasterboard was more favourable to mould growth when compared to "tabique" walls. Moreover, the roughness of the substrates and the sampling location had also significant impact on the results.

Bioactive Factors-imprinted Scaffold Vehicles for Promoting Bone Healing: The Potential Strategies and the Confronted Challenges for Clinical Production
Authors: Xue Peng-Peng , Yuan Jian-dong , Yao Qing , Zhao Ying-Zheng , Xu He-Lin
Published: June 2020

Wound repair of bone is a complicated multistep process orchestrated by inflammation, angiogenesis, callus formation, and bone remodeling. Many bioactive factors (BFs) including cytokine and growth factors (GFs) have previously been reported to be involved in regulating wound healing of bone and some exogenous BFs such as bone morphogenetic proteins (BMPs) were proven to be helpful for improving bone healing. In this regard, the BFs reported for boosting bone repair were initially categorized according to their regulatory mechanisms. Thereafter, the challenges including short half-life, poor stability, and rapid enzyme degradation and deactivation for these exogenous BFs in bone healing are carefully outlined in this review. For these issues, BFs-imprinted scaffold vehicles have recently been reported to promote the stability of BFs and enhance their half-lifein vivo. This review is focused on the incorporation of BFs into the modulated biomaterials with various forms of bone tissue engineering applications: firstly, rigid bone graft substitutes (BGSs) were used to imprint BFs for large scale bone defect repair; secondly, the soft sponge-like scaffold carrying BFs is discussed as filling materials for the cavity of bone defects; thirdly, various injectable vehicles including hydrogel, nanoparticles, and microspheres for the delivery of BFs were also introduced for irregular bone fracture repair. Meanwhile, the challenges for BFs-imprinted scaffold vehicles are also analyzed in this review.

Karst springs in Slovenia: trend analysis
Authors: Jelen Maja , Mikoš Matjaž , Bezak Nejc
Published: June 2020

Karst springs and aquifers are important sources of drinking water, so knowledge about the dynamics of changes in the hydrological characteristics of karst springs is especially important. This paper presents a hydrological trend analysis conducted for 14 karst springs in Slovenia. The trends of low, mean, and high annual flows were analyzed for the period from 1961 to 2013. Additionally, changes in annual rainfall, air temperature, and water temperature were investigated. The relationship between precipitation and discharges was also examined, as well as that between water and air temperature. Results indicate that low and mean flows in the selected springs are decreasing. In the case of high flows, no significant decreasing or increasing trend could be detected. For air temperature, the trend results were positive and statistically significant with the selected significance level. Some precipitation stations showed a significant decrease in the annual rainfall. Because the relationship between annual precipitation and mean flows is relatively high, the rainfall decrease could be the main reason for the decrease in low and mean flows. Moreover, the retention times of karst springs are relatively short. Some of the investigated springs are located in the Mediterranean part of the country where issues with drinking water supply occur commonly in the summer. If a similar dynamic continues, water scarcity problems can be expected in the future. The climate change models also predict such dynamics.

Published: June 2020

Plastic waste can cause serious environmental problems. This can be overcome by various efforts; one of them is by replacing the use of conventional plastic with biodegradable plastic. Biodegradable plastic can be produced from tubers containing starch. The purpose of this study was to explain the suitability of two tuber species with typical protein quality and different starch structures. Starch was obtained from suweg tuber (Amorphophallus campanulatus) and ganyong (Canna edulis Ker). The material invested was obtained by dissolving 4 grams of each starch, each of which was dissolved with distilled water then added with various weight carrageenan. The tensile strength of biodegradable plastic was tested using tensile testing machines, biodegradation of soaked plastics using EM4 (Effective Microorganism) with reduced weight measurements, and Fourier Transform Infra-Red (FTIR) was used to identify the structure of compounds contained in biodegradable plastics. The tensile strength test results of biodegradable plastic from ganyong/canna tubers were 3.35 MPa with elongation of 13.51%, while the plastic from suweg tubers of 2.45 MPa with elongation was 13.68% on the addition of 5% carrageenan, respectively. Plastic degradation testing obtained plastic decomposition up to 100% in 37 days for ganyong and 34 days for suweg, respectively. It showed that the plastics was easily degraded. Identified by FTIR showed chemical structures of OH phenolic alcohols, C = O carbonyls, CO esters, NH amides and amines, and C≡C alkyne.

Published: June 2020

Isopropyl alcohol is widely used as industrial chemical intermediates and common solvents in households, pharmaceuticals, food, cosmetics, and medical purposes. The high purity of isopropyl alcohol requires special separation from its impurity i.e. water due to isopropyl alcohol and water form an azeotropic point, which is difficult to separate using a conventional distillation method. The azeotropic point of this mixture is at isopropyl alcohol mole fraction of 0.68 and temperature of 353.4 K. One of the optimum methods to separate an azeotrope point is through the extractive distillation which use a third component as a solvent. Glycerol is one of the solvents which can be used as a potential entrainer in the extractive distillation. Glycerol is produced in the biodiesel production as a by-product. Moreover, glycerol is an eco-friendly chemical. In this work, the simulation of the extractive distillation of isopropyl alcohol/water system with glycerol as an entrainer was simulated using Aspen Plus. The Non-Random Two-Liquid (NRTL) model was used as thermodynamic model in the simulation.  The effect of stage number, binary feed stage, entrainer feed stage, and reflux ratio to the purity of isopropyl alcohol, and reboiler-condenser duties were examined to achieve the optimum design for the extractive distillation column with less energy requirements. The simulation results showed that the optimum configurations in the extractive distillation column design are at 25 theoretical stages, binary feed stage (BFS) of 20, entrainer feed stage (EFS) of 2, and reflux ratio (RR) of 0.5 to produce isopropyl alcohol with the purity of 99.27%. The design and sizing of the extractive distillation column were also proposed in this work.

The ensuing COVID-19 pandemic poses unprecedented and daunting challenges to the routine delivery of oncological and supportive care to patients with breast cancer. Considerations include the infective risk of patients who are inherently immunosuppressed from their malignancy and therapies, long-term oncological outcomes from the treatment decisions undertaken during this extraordinary period, and diverted healthcare resources to support a coordinated whole-of-society outbreak response. In this review, we chronicle the repercussions of the COVID-19 outbreak on breast cancer management in Singapore and describe our approach to triaging and prioritising care of breast tumours. We further propose adaptations to established clinical processes and practices across the different specialties involved in breast oncology, with references to the relevant evidence base or expert consensus guidelines. These recommendations have been developed within the unique context of Singapore’s public healthcare sector. They can serve as a resource to guide breast cancer management for future contingencies in this city-state, while certain elements therein may be extrapolatable to other medical systems during this global public health emergency.
Symmetric functions on spaces $\ell_p(\mathbb{{R}}^n)$ and $\ell_p(\mathbb{{C}}^n)$

Published: June 2020

This work is devoted to study algebras of continuous symmetric, that is, invariant with respect to permutations of coordinates of its argument, polynomials and $*$-polynomials on Banach spaces $\ell_p(\mathbb{R}^n)$ and $\ell_p(\mathbb{C}^n)$ of $p$-power summable sequences of $n$-dimensional vectors of real and complex numbers resp., where $1\leq p < +\infty.$ We construct the subset of the algebra of all continuous symmetric polynomials on the space $\ell_p(\mathbb{R}^n)$ such that every continuous symmetric polynomial on the space $\ell_p(\mathbb{R}^n)$ can be uniquely represented as a linear combination of products of elements of this set. In other words, we construct an algebraic basis of the algebra of all continuous symmetric polynomials on the space $\ell_p(\mathbb{R}^n).$ Using this result, we construct an algebraic basis of the algebra of all continuous symmetric $*$-polynomials on the space $\ell_p(\mathbb{C}^n).$ Results of the paper can be used for investigations of algebras, generated by continuous symmetric polynomials on the space $\ell_p(\mathbb{R}^n),$ and algebras, generated by continuous symmetric $*$-polynomials on the space $\ell_p(\mathbb{C}^n).$

Published: June 2020

Introduction: Ilizarov technique is one of the excellent methods used for bony lengthening. The current literature states that the maximum possible amount of tibial lengthening by bifocal transport of an Ilizarov apparatus was 22 cm, while the maximum amount of tibial lengthening by unifocal transport of an Ilizarov apparatus was 14.5 cm.Case report: 40 years old Saudi teacher was presented with an open fracture at the right tibia of type 3B. The second debridement was done and ended up with 21.49 cm bone loss of the middle Tibial segment. Local flap plastic surgery was done to cover the skin defect and the bone transport was done at a rate of 1mm/day. The overall healing was excellent, and the patient returned to his pre-injury functional activity and rejoined his job as a teacher.Conclusion: Thus, the current case report is a unique new record of 21.49 cm of tibial lengthening achieved by the Ilizarov apparatus using unifocal transport. This will be a treatment hope for patients with excessive bone loss.
Grundlagen einer rationalen Klimapolitik
Authors: Pritzl Rupert
Published: June 2020

Der Schutz des Klimas ist eine große globale Herausforderung. Eine rationale Klimapolitik muss effektive und kosteneffiziente Maßnahmen ergreifen, die Verteilungswirkungen berücksichtigen und gesellschaftliche Akzeptanz herstellen. Eine CO2-Bepreisung sollte als zentrales Lenkungsinstrument eingeführt und in einem globalen Emissionshandel institutionalisiert werden. Die bisherige deutsche Klimapolitik erweist sich als kleinteilig, ineffizient und ineffektiv. Das „Klimapaket 2030“ der Bundesregierung ist nur ein Tippelschritt zu einem erforderlichen grundlegenden Strategiewechsel.
What Does it Take to Successfully Implement a Hybrid Offering Strategy? A Contingency Perspective
Authors: Dannenbaum Judith , Edinger-Schons Laura Marie , Rese Mario , Plötner Olaf , Wieseke Jan
Published: June 2020

Since the beginning of the 1990s, selling integrated bundles of goods and services – so-called hybrid offerings – have emerged as a trend in industrial markets. Hybrid offerings are proposed to help companies to differentiate in highly competitive markets and to generate higher margins. Meanwhile, as anecdotal evidence suggests, many companies still fail to offer such hybrid offerings successfully. Hence, the purpose of this study is to test whether a positive relationship between implementing a hybrid offering strategy and companies’ financial success exists and which contingency factors moderate this relationship. By using a cross-industry survey of N=299 European industrial companies from various industries which combine products and services to varying degrees, the study at hand reveals that a hybrid offering strategy is especially successful under conditions of fierce competition. Results further reveal that a company’s proactive decision to implement a hybrid offering strategy (instead of a mere reaction to customer pressure) affects the performance gains that the company can reap from hybrid offerings. Furthermore, results indicate that capabilities such as top-management commitment, modularization, as well as a supporting infrastructure significantly leverage the success of a hybrid offering strategy. These results have important implications for academic knowledge on hybrid offerings as well as the management of service infusion processes in companies.

Published: June 2020

The article aims to analyse and evaluate the influence of marketing tools on consumer behavior. In order to investigate the topic, a thorough analysis of scientific literature was performed and followed by systematization and generalization of different theories and academic sources. The research revealed that the use of various marketing tools such as advertising and online communication through social media or blogs allows to gain exposure for businesses and have a positive impact on consumer behavior. On the other hand, it is important to note that both micro and macro environment have to be taken into account, as individuals might make different decisions based on the surrounding cultural, social and market contexts. Based on the proposed theoretical model of the influence of marketing tools on consumer behavior, there is a positive correlation between sociological variables, external stimuli and marketing communications. The holistic model should be empirically validated and revised once investigated in practice.
Innovation planning
Authors: Nazif Emine
Published: June 2020

The report examines theoretical assumptions regarding the nature and importance of innovation. Regardless of the diversity we see in terms of defining different types of innovation, we can come to the conclusion that all definitions have one common feature and it relates to focusing on the presence of something new and different. Innovation planning processes are discussed by indicating that they are aimed at defining specific actions so that the objectives set out in the company's innovation strategy can be achieved. The most important functions of planning are to coordinate the efforts of the participants in the innovation process and to link business objectives and opportunities for future development. Emphasis is placed on the importance of innovation for each organization and the necessary investment of efforts for appropriate innovation planning that provides competitive advantages.
МОДЕРНІЗАЦІЯ УКРАЇНСЬКОЇ ГАЗОТРАНСПОРТНОЇ СИСТЕМИ: НАЦІОНАЛЬНІ ТА МІЖНАРОДНІ ВИКЛИКИ
Authors: ПАНЧЕНКО Євген
Published: June 2020

Показано, що газотранспортна система України відіграє ключову роль у національній енергетиці та поставках російського газу до ЄС. Проте вона є дуже застарілою, має низьку конкурентоспроможність і потребує невідкладної модернізації. Особливо це стосується техніко-технологічних та організаційно-управлінських складових української ГТС.У цьому зв’язку необхідно комплексно дослідити умови, напрями і механізми модернізації української ГТС у контексті конвергенції українського та європейського газових ринків для посилення енергетичної безпеки і досягнення сталого розвитку України та ЄС на основі дотримання вимог Третього енергопакета.Виявлено особливості модернізації ГТС України, які пов’язані з її великими масштабами (понад 38,5 тис. км), зношеністю основних фондів, дуже неефективною системою управління, низькою (менш як на 50%) завантаженістю виробничих потужностей, що призводить до малої ефективності функціонування ГТС, яка потребує значних коштів для модернізації.Важливим напрямом техніко-технологічної модернізації ГТС є якнайшвидше створення спеціально для України промислових газотурбінних двигунів нового покоління, здатних підвищити ККД до рівня кращих зарубіжних аналогів. Окремою складовою техніко-технологічної модернізації української ГТС є адаптація її ланок до функціонування в умовах неповного використання транспортно-перекачувальних потужностей.Зроблено висновок про те, що без партнерства з провідними іноземними газотранспортними компаніями як у процесі поточної модернізації, так і надалі підвищити конкурентоспроможність української ГТС до європейського рівня принципово неможливо. Партнери потрібні українському оператору не стільки для обміну досвідом, скільки для кардинальної модернізації вітчизняної ГТС. Обраний нами партнер повинен взяти на себе частину відповідальності за майбутню долю української ГТС.

BACKGROUND:

Respiratory syncytial virus (RSV) is a major cause of hospitalized acute respiratory illness (ARI) among young children. With RSV vaccines and immunoprophylaxis agents in clinical development, we sought to update estimates of US pediatric RSV hospitalization burden.

METHODS:

Children <5 years old hospitalized for ARI were enrolled through active, prospective, population-based surveillance from November 1, 2015, to June 30, 2016, at 7 US pediatric hospital sites. Clinical information was obtained from parent interviews and medical records. Midturbinate nasal and throat flocked swabs were collected and tested for RSV by using molecular diagnostic assays at each site. We conducted descriptive analyses and calculated population-based rates of RSV-associated hospitalizations.

RESULTS:

Among 2969 hospitalized children included in analyses, 1043 (35%) tested RSV-positive; 903 (87%) children who were RSV-positive were <2 years old, and 526 (50%) were <6 months old. RSV-associated hospitalization rates were 2.9 per 1000 children <5 years old and 14.7 per 1000 children <6 months old; the highest age-specific rate was observed in 1-month-old infants (25.1 per 1000). Most children who were infected with RSV (67%) had no underlying comorbid conditions and no history of preterm birth.

CONCLUSIONS:

During the 2015–2016 season, RSV infection was associated with one-third of ARI hospitalizations in our study population of young children. Hospitalization rates were highest in infants <6 months. Most children who were RSV-positive had no history of prematurity or underlying medical conditions, suggesting that all young children could benefit from targeted interventions against RSV.

Radiation arteritis is not an uncommon clinical situation, given that almost 50% of patients with cancer receive radiotherapy in the course of treatment. Radiation effects are non-specific, and late radiation tissue injury presentation can be very variable. However, radiation arteritis has some unique clinical and radiological features, with consequent special therapeutic considerations. Iliac radiation arteritis may be accompanied by radiation-associated iliac vein disease and small vessel disease. Therefore, diagnostic and therapeutic plans should be directed toward all possible late radiation effects as relevant. Despite the complexity of the disease process and diagnostic challenges, treatment can be very straightforward if adequately planned. Otherwise, limb loss and/or life-threatening complications can rapidly ensue. This article highlights the natural history of radiation arteritis, with a particular emphasis on the iliac segment, and discusses the risk potentials of this condition, given that limb loss may be multifactorial, not merely because of the iliac arterial flow interruption. The main lines of management are also briefly discussed.
PENGARUH PERBEDAAN JENIS KAYU BAKAR DAN LAMA PENGASAPAN TERHADAP MUTU SENSORI IKAN PATIN ASAP (Pangasius pangasius)

Published: June 2020

Lama pengasapan dan jenis kayu yang digunakan akan mempengaruhi mutu ikan asap yang dihasilkan, karena setiap jenis kayu mengandung senyawa kimia yang berbeda-beda. Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan kayu bakar yang digunaan dan lama pengasapan terhadap mutu ikan patin asap. Ikan patin yang digunakan berukuran 200-300 gr/ekor. Pengujian yang dilakukan adalah uji hedonik (kesukaan) terhadap kenampakan, bau, rasa dan tekstur ikan patin asap. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan perlakuan jenis kayu (kayu karet dan kayu rambutan) dan lama pengasapan (8 jam, 9 jam, dan 10 jam). Data yang diperoleh dianalisis dengan Kruskal Wallis. Dari hasil pengujian hedonik diketahui bahwa panelis lebih menyukai ikan patin yang diasap dengan kayu rambutan selama 9 jam. Uji statistik menunjukkan bahwa perbedaaan jenis kayu (kayu karet dan kayu rambutan) tidak berpengaruh nyata terhadap nilai hedonik ikan patin asap (Chi Square = 3,627 dan p-value 0,057 > 0,05), sedangkan lama pengasapan pada rentang waktu 8 jam, 9 jam dan 10 jam, berpengaruh nyata terhadap nilai hedonik ikan patin asap (Chi Square = 7,506 dan p-value 0,023 <  0,05).
The Novel Coronavirus 2019 Epidemic and the Kidneys
Authors: Salvadori Maurizio , Tsalouchos Aris
Published: June 2020

The Severe Acute Respiratory Syndrome Coronavirus 2 is a recent disease that originated in China by the end of 2019. The origins of the dis-ease can be traced to bats, but it has been transmitted to humans, and the inter-human transmission is particularly rampant which has led to a pandemic of unseen proportions. The organ principally involved is the lungs, and severe pneumonia with lack of oxygen leads to fatalities. The aim of this review was to study the involvement of the kidneys with regard to COVID-19 infection and how the disease may affect people on hemodialysis or those who have undergone a kidney transplant. Indeed, the virus, in addition to the lungs, may affect other vascularized organs to a common receptor on lung epithelium and the endothelium of any organ. The kidney, which has a large endothelium surface, is affected, and COVID-19 may lead to acute renal failure. On the other hand, the virus may easily spread among people who are on hemodialysis three times a week. People on hemodialysis may have low immunity, and the virus may have dangerous effects on such people. Finally, renal transplant patients may be easily affected, and the virus may have severe consequences, even death. We will summarize the principal prophylactic measures to be adopted and the therapeutic measures available. Clearly due to the recent occurrence of the pandemic the majority these measures lack a basis in evidence-based medicine and only highlight the efforts to limit COVID-19 induced damage.
