Authors: Aguilar Carpio Cid
Published: September 2018

Diaphorina citri Kuwayama es un insecto plaga que afecta los cultivos de limón mexicano, sus daños directos no representan gran importancia, pero el Huanglongbing (HLB), enfermedad bacteriana ocasionada por Candidatus liberibacter spp., que produce pérdidas millonarias al país e incluso puede provocar la desaparición de la citricultura en la zona. Si no se detiene el avance del vector, sería catastrófico para los productores citrícolas de la región, ya que el puerto de Acapulco es un productor potencial de fruto fresco de limón. Por tanto, el objetivo de esta investigación fue conocer la fluctuación poblacional y con ello determinar los índices de mayor crecimiento de D. citri con referencia a la fenología y condiciones climatológicas. El estudio se realizó en la zona agrícola del municipio de Acapulco Guerrero. Los muestreos se realizaron del 3 de febrero al 28 de noviembre del 2014. Se seleccionaron huertas de limón mexicano (Citrus L.), en un área de 1,559 ha. Se utilizaron 1,399 trampas pegajosas amarillas, las caules se distribuyeron en las orillas de las huertas a una altura de 1 a 2 m en la copa del árbol. Cada semana se recogían las trampas y se contaba el número de psilidos adultos capturados. Tambien se consideraron las etapas fenológicas del cultivo como: crecimiento vegetativo, floración, amarre, desarrollo del fruto y cosecha de frutos. Además, se llevó un registro de las temperaturas promedio y precipitación. La población de adultos de D. citri se encontraron durante todo el periodo de muestreo, siendo los meses de abril y noviembre donde se presentaron las mayores poblacionales favorecidas por la presencia de optimas temperaturas y bajas precipitaciones.
A ritmikai készségek fejlődése 12 éves korig
Authors: Mucsi Gergő
Published: September 2018

A ritmikai készségek fejlődése más készségek fejlődési sajátosságaihoz hasonlóan egy gyorsuló, majd fokozatosan lassuló folyamatként jellemezhető. A fejlődés legintenzívebb időszaka óvodáskorra és kisiskoláskorra tehető. A gyermekek zenei képességeinek fejlesztése is ebben a fogékony korban lehet a legeredményesebb. A ritmikai készségek fejlődése más, nem zenei képességek fejlődését is segíti. Számos kutatás igazolja a ritmikai készségek pozitív hatásait a nyelvi képességekre, az olvasásra, a matematikai gondolkodásra, a memóriára és az intelligenciára is. A ritmikai készségek fejlettsége kiemelt fontossággal bír, előrejelzője lehet a későbbi tanulmányi eredményességnek is. A tanulmány három korcsoportra bontva (3 éves korig, 3–6 éves kor között, 6–12 éves kor között) mutatja be a ritmikai készségek fejlődésének életkori jellemzőit és fejlesztési lehetőségeit. A tanulmány célja továbbá, hogy ismertesse az óvodai zenei nevelés legfontosabb szempontjait, valamint az alsó fokú iskolai oktatás kerettantervének ritmikai fejlesztésre vonatkozó alapelveit.
A cél szentesíti az (IKT-)eszközt a zeneoktatásban?
Authors: Szabó Norbert
Published: September 2018

A digitális eszközök használatában rejlő motivációs potenciált már számos kutatás bebizonyította. Ennél azonban jóval kevesebb vizsgálat foglalkozik az IKT-eszközök alkalmazásának hatásával a zenei képességek fejlesztése szempontjából. Ennek egyik oka az is lehet, hogy az egyre jobb minőségű hardvereken csak lassan bővül a zenei osztálytermekben is eredményesen használható applikációk, szoftverek száma. Tanulmányunkban olyan ingyenes alkalmazást mutatunk be, amelynek hasznosságáról és hatékonyságáról még empirikus adatokkal ugyan nem rendelkezünk, de gyakorlati tapasztalataink és az a tény, hogy világszerte több mint hétmillió felhasználója van, jó apropót ad annak átgondolására, hogy a digitális eszközök hogyan segíthetik a zenetanulás hatékonyabbá tételét.

Konflik Tata Ruang Kehutanan Dengan Tata Ruang Wilayah (Studi Kasus Penggunaan Kawasan Hutan Tidak Prosedural Untuk Perkebunan Sawit Provinsi Kalimantan Tengah)
Authors: Setiawan Eko N , Maryudi Ahmad , Purwanto Ris H , Lele Gabriel
Published: September 2018

AbstractLaw No. 26 Year 2007 on Spatial Planning (UUPR) mandated that all levels of government administration, ranging from the national, provincial, district/ city are obligated to prepare Spatial Plan (RTR). Until 2012, Central Kalimantan is one of the provinces which have not completed its Spatial Plan; one of the reasons was the lack of spatial integration of forestry spatial planning and provincial spatial planning of Central Kalimantan.The absence of spatial integration of forestry and provincial spatial planning of Central Kalimantan has the implication in triggering conflicts of land use. Forest areas were converted into oil palm plantations without any official procedures. There are 282 units of oil palm companies, occupying 3.9 millions hectares of forest area, with non-procedural procedures to convert forest area into oil palm plantation.To resolve this problem, the Government has revised the regulation of forest conversion by issuing PP No. 60/2012, provides opportunities for oil palm plantations, which under the Law of Forestry located in forest area but based on RTRWP of Central Kalimantan lies on APL or cultivation area, given the opportunity to re-apply the permit/license.  IntisariUndang- Undang No. 26 Tahun 2007 tentang Penataan Ruang (UUPR) mengamanatkan bahwa semua tingkatan administrasi pemerintahan, mulai dari nasional, provinsi, kabupaten/kota diwajibkan menyusun Rencana Tata Ruang (RTR). Kalimantan Tengah sampai dengan tahun 2012 merupakan salah satu Provinsi yang belum menyelesaikan Tata Ruang, salah satu penyebabnya karena belum adanya padu serasi antara tata ruang kehutanan dengan tata ruang Provinsi Kalimantan Tengah.Implikasi dari tidak adanya padu serasi antara tata ruang kehutanan dengan tata ruang provinsi Kalimantan Tengah adalah terjadinya konflik dalam penggunaan ruang, dimana terjadi penggunaan kawasan hutan tidak prosedural untuk perkebunan sawit di dalam kawasan hutan di Provinsi Kalimantan Tengah sebanyak 282 unit perusahaan sawit seluas 3,9 juta hektar.Upaya penyelesaian permasalahan penggunaan kawasan hutan untuk perkebunan sawit di Provinsi Kalimantan Tengah diakukan dengan revisi kebijakan tentang alih fungsi hutan PP nomor 60 tahun 2012 yang memberikan kesempatan bagi perkebunan sawit yang berdasarkan Undang-Undang Kehutanan berada di dalam kawasan hutan namun berdasarkan RTRWP Provinsi Kalimantan Tengah berada di kawasan APL maupun budidaya, diberikan kesempatan untuk mengurus perijinannya.
Stories of transition: US Veterans’ narratives of transition to civilian life and the important role of identity
Authors: Keeling Mary
Published: September 2018

Introduction: To date, investigations of Veterans’ transition to civilian life after military service have tended to focus on the experiences of those with mental or physical health difficulties or on employment challenges and homelessness. This study aimed to gain a deep understanding of Veterans’ transition to civilian life, the challenges they face, and the adaptive and maladaptive ways in which they manage them. Methods: A narrative approach was used to afford the Veterans an opportunity to share their experiences through their transition story. Six male Veterans residing in the Chicagoland area who had left the military between 1 and 12 years earlier were interviewed using a narrative approach. Results: Narrative analysis led to the emergence of three master narratives: narratives of the challenges, narratives of readiness, and narratives of continued military values. The narratives the Veterans shared highlighted not only the importance of practical readiness for transition but also the need for a fundamental addition to how Veteran transition is considered that includes psychological considerations of the impact on identity and the potential for existential crisis. Discussion: Appraising transition only in terms of measurable factors such as employment, living conditions, and health likely overlooks those experiencing psychological challenges and sub-clinical mental health difficulties. The proposed fundamental addition has implications for work with Veterans in various health care settings and for existing transition programs, including a consideration of the role of identity.
Mild traumatic brain injury in military service personnel: key issues and considerations
Authors: Doneva Silviya P.
Published: September 2018

Introduction: This article considers mild traumatic brain injury (mTBI). More specifically, it aims to illustrate the current picture of mTBI among military personnel, including its definition, prevalence rates, markers, possible long-term consequences, and current approaches to treatment. Methods: Information is drawn from current reports published by the UK Ministry of Defence (MoD) and the World Health Organization Collaborating Centre Task Force on Mild Traumatic Brain Injury and high-impact academic research in the field, mainly making use of US and UK military data. Moreover, this article also includes exclusive data on the number of mTBI cases among the UK military for the period between 1 April 2008 and 31 March 2016 that the author received from the Department of Defence Statistics at the MoD. Results: There is still no agreement on the classification and etiology of and best approach to the management of mTBI. Furthermore, prevalence rates vary considerably among UK and US service personnel. Although current MoD data show that the mTBI rates among UK service personnel are low, the seriousness of the potential long-term effects of mTBI should not be overlooked. Discussion: Because mTBI is the most controversial form of TBI in terms of its cause and nature, it continues to raise ardent debates among researchers and clinicians. This article recognizes this and thus incorporates as many different perspectives as possible.

Published: September 2018

Introduction: Suicide prevention for Veterans is a public health priority. However, it has been challenging to study suicide in Canadian Veterans post-release from the military. The Veteran Suicide Mortality Study (VSMS) has assembled data on the risk of death by suicide for Canadian Veterans compared to other Canadians. Methods: This was a record linkage study of Canadian cause of death data from Statistics Canada linked with a cohort of Canadian Veterans from pay data of the Canadian Armed Forces (CAF). The population-based cohort included Veterans released with Regular Force or Reserve Force Class C service for the period 1976–2012. Death by suicide was identified by International Classification of Diseases (ICD) codes. Estimates of relative risk for suicide were calculated using standardized mortality ratios (SMRs) with the Canadian general population (CGP) as the reference. Results: Male Veterans had a higher risk of suicide compared to the CGP (SMR = 1.36 [95% CI, 1.30–1.44]). Female Veterans also had a higher risk (SMR = 1.81 [95% CI, 1.40–2.31]). Suicide risk for Veterans was consistently higher than for the CGP over the 37 years of follow-up. Risk for male Veterans was highest for those under 25 years old and decreased with age, but risk for females was higher than the CGP regardless of age. Discussion: The finding of higher risk of death by suicide for both male and female Veterans compared to the CGP informs the action plans of the recently released suicide prevention strategy. Future studies will identify other characteristics of subgroups of Veterans at higher risk of suicide.
Reflections on the Spiritual Dynamics of the Bahá’í Faith
Authors: Bausani Alessandro
Published: September 2018

True spiritual force has the power to change matter. The spiritual force released by Bahá’u’lláh has the power to change the entire world. Humans, unaided, cannot understand the fundamental problems of mankind; a prophet like Bahá’u’lláh gives us the power both to understand human problems and to correct them. Values do not derive from the individual but from the central Force of the universe: God. Only the religious mind can place moral issues like sin and death in the context of the realities of the universe. The acquisition of virtues such as a love of order, moderation, obedience, and humility are among the requisites for preparing the human heart for the new society Bahá’u’lláh’s teachings will bring. However, religion should be practical and other-oriented, not mystical and introspective. The spiritual force released by the good actions of believers has a more pervasive influence than the same action of a nonbeliever. The gathering together of Bahá’ís in prayer will augment these spiritual forces and dispel ignorant ideas of religion.
Scholarship
Authors: Hatcher William
Published: September 2018

This paper defines scholarship as disciplined intellectual activity undertaken to help determine the truth of some matter or else to apply in a practical way some previously determined truth. More specifically, Bahá’í scholarship seeks to understand and/or apply truths contained in the writings of the Bahá’í Faith; it may also involve historical/critical studies of the Bahá’í Faith as a social phenomenon. With regard to the first type of Bahá’í scholarship, we examine certain passages in the Bahá’í writings which comment on these writings themselves and which describe the kinds of truths they contain. In particular, it is seen that the Bahá’í writings contain important propositional truths and not just moral injunctions (so-called normative propositions). The relationship between scholarship and other human enterprises is also discussed. The Bahá’í conception of scholarship is seen to be unusually broad in scope and to provide thereby the basis for a much greater harmony between scholarship and the various other activities carried on within the Bahá’í community.
Development of a Module to Teach Basic Concepts of Interfacing and Connectivity in Internet of Things
Authors: Ayodele Obasegun Tekena
Published: September 2018

This paper presents a basic laboratory training module aimed at helping undergraduate students understand the interfacing and connectivity issues involved in the Internet of things (IoT). The training module uses a sequential teaching approach to draft quasi-experiments for teaching basic IoT concepts. Interfacing includes identification, embedded sensing and embedded actuating while connectivity includes wireless connectivity and web/ mobile services. An IoT function (control and/or measurement) is first selected by users based on the physical variable of interest and the action to be carried out. The user will also select a connectivity option based on network types and transmission technologies available for communication between a sensor and/or an actuator and a gateway. The available connectivity options in this work are Bluetooth and RF. An interface is then setup based on the choices made using Arduino Pro Mini as microcontroller. Arduino Yun and a smartphone are the available gateway options depending on the connectivity option of the interface. When Bluetooth is the connectivity type on theinterface, the smartphone is used as gateway while Arduino Yun serves as the gateway when RF is the connectivity option on the interface. The training module is accompanied with an instruction manual which contains instructions on the set ups and short notes on signals andsystems, Analog to Digital Converters (ADC), Digital to Analog Converters (DAC), Wireless Sensor Networks (WSN), etc. The training module was tested with 100 randomly selected students. A few students had problems setting up the interface correctly. Coding the Arduino boards was a challenge for some of the students while a few others had challenges with creating sensor nodes. Choosing the correct connectivity type to match a gateway was the most challenging for the students.
Development of a Competitive and Collaborative Platform for Block Diagram and Resistive Circuit Reduction in a Basic Electrical Engineering Course
Authors: Ayodele Obasegun Tekena
Published: September 2018

Competition and collaboration are two universal ingredients in all human cultures. Competition has beenobserved over time as a phenomenon that has helped people achieve the very best of their potentials in their various fields. Competition has also helped individuals achieve feats they would not have ordinarily achieved as they are pushed beyond their limits. The same can also be said of cooperation and collaboration, which can be used to achieve specific goals or objectives. Hence, both competition and collaboration can be vital in creating a healthy learning process among students. This paper discusses a competitive and collaborative platform onthe learning process for two selected online courses in Electrical Engineering. Using a platform developed in LabVIEW programming language, a community of students were encouraged to compete online as they try to reduce block diagrams of subsystems in Control Engineering as well as reduce given Series-Parallel Resistor Circuits in the shortest time and amount of steps possible. At the end of each trial, students can view the finish time of other students and can share, online, their individual solutions with the community as well as discuss ideas such as reduction techniques they find most expedient via a public online notepad. This creates a means of learning from the community. The platform helps to passively induce a competitive and collaborative perspective in the learning pathway of students, thereby improving the interest and experience of students in the selected subject areas. The platform uses an online server to maintain communications from all the students in their various locations. Students can view the timed performance of their counterparts on a leadership board thereby engendering induced competition in the learning community. The instructor or administrator can also monitor activities in the community from a server portal.

Talking about the same but different? Understanding social movement and trade union cooperation through social movement and industrial relations theories
Authors: Zajak Sabrina , Gortanutti Giulia , Lauber Johanna , Nikolas Ana-Maria
Published: September 2018

In the context of continuing political, social, and economic crises, trade unions in most European countries are seen as weakened, protest as having little influence, and the solidarity between European populations as damaged. Under these circumstances, scientists and practitioners have placed hope in the cooperation of social movements and trade unions in order to revitalise trade unions and achieve common goals. However, the conditions for forming alliances between trade unions and social movement organisations have, thus far, been primarily researched, and partially theorised, from the point of view of different disciplines. In doing so, approaches that emphasise the strategic alignment with resources and context diverge from approaches that highlight the relevance and necessity of shared ideologies or identities. This contribution aims to bring existing approaches from movement and industrial relations research into dialogue with each other and calls for a further integration of both perspectives. It contributes to a more holistic understanding of joint movement and trade union action current concepts such as social movement unionism cannot provide. It uses two examples to show that instrumental, strategy-driven modes and identity-based, culturally-driven modes of cooperation are not contradictory. There are situations in which strategic decisions on resources and political influence are more decisive than ideological proximity and vice versa. These findings are of social and scientific relevance for understanding mechanisms of solidarity construction and processes of bridging differences even in increasingly fragmented and unequal societies.
Bewegung im Betrieb. Organizing-Projekte und die Revitalisierung der
industriellen Beziehungen
Authors: Thünken Oliver
Published: September 2018

Der Beitrag argumentiert, dass gewerkschaftliche Organisierung im Rahmen von betrieblichen Organizing-Projekten den Charakter von sozialen Bewegungen annimmt und damit die Verfasstheit der industriellen Beziehungen in Deutschland herausfordert. Während das duale System der Interessenvertretung repräsentative, auf Ausgleich und Kompromiss angelegte und zudem stark verrechtlichte Verhandlungssysteme etabliert, werden im Rahmen von Organizing-Prozessen die Beschäftigten selbst zur aktiven Gestaltung der Interessenpolitik im Betrieb motiviert. Dabei kommt es zu einer bemerkenswerten beteiligungsorientierten Erweiterung des dualen Systems auf betrieblicher Ebene, mit der auch Potenziale für die Revitalisierung der industriellen Beziehungen verbunden sind.

Background: Kidney transplantation is the preferred treatment for end stage kidney disease (ESKD). Live related donor kidney transplant was started in BIRDEM General Hospital, Bangladesh, on 6th November 2004. The aim of this study was to share our last 10 years’ experience of live related donor kidney transplant.Methods: A questionnaire was formed and data were collected from the hospital records. We retrospectively evaluated patients’ clinical and laboratory findings.Results: A total of 111 live related donor kidney transplants were performed from 2004 to 2014. Male:female was 2.3:1. The mean age of the recipients was 37.45 ± 10.58 years. The causes of ESKD were chronic glomerulonephritis (CGN) (52, 46.9%), diabetes mellitus (DM) (31, 27.9%), hypertension (26, 23.4%), chronic pyelonephritis (1, 0.9%) and obstructive nephropathy (1, 0.9%). Pre-emptive transplantation was done in 4 (3.6%) patients. Patients on continuous ambulatory peritoneal dialysis and haemodialysis were 2 (1.8%) and 105 (94.6%) respectively. Most of the donors were siblings (55.9%). Majority (64.9%) had an uncomplicated recovery. The commonest complication during post-transplant hospital stay was infection (27.0%), mostly urinary tract infection (21.6%). Surgical failure was experienced in 1 (0.9%) and acute rejection was noted in 2 (1.8%) patients. Other complications were renal vein thrombosis (1, 0.9%), haemolytic uremic syndrome (1, 0.9%), acute tubular necrosis (1, 0.9%), peri-renal collection (1, 0.9%), pericardial effusion (1, 0.9%) and clot retention in urinary bladder (2, 1.8%). Mean post-transplant hospital stay was 12.39 ± 4.27 days. Mean duration from surgery to normalization of serum creatinine was 5.75 ± 4.15 days. During discharge, 71.2% patients had normal renal function (RF) with mean serum creatinine 1.03 ± 0.15 mg/dl and 26.1% patients had gradually improving RF with mean serum creatinine 2.01 ± 1.04 mg/dl. As induction, 61 (55%) patients received basiliximab and as maintenance therapy all patients received oral prednisolone, calcinurine inhibitor and mycophenolate. In the first year of transplant, 49.5% patients suffered from infections, of which urinary tract infection was the commonest (55.9%). Incidence of chronic allograft nephropathy in CGN, DM and hypertension patients were 25%, 19.4% and 23.1% respectively. Graft survival at 1 year, 3 years and 5 years was 94.06%, 85.88% and 77.27% respectively. Patient survival at 1 year, 3 years and 5 years was 98.1%, 88.24% and 84.09% respectively.Conclusions: Our results are comparable or in some aspects, even better in comparison to other centers of both developing and developed world. In a center of a developing country with limited facility and resource, these achievements are encouraging.Birdem Med J 2018; 8(3): 198-202

Background: Throughout the world, a demographic revolution is underway. The proportion of older people is growing faster than any other group. A growth spurt in the number of elderly persons has resulted from improvements in both social living conditions and medical care. This poses tremendous challenges to health and social policy planners, particularly because disease patterns will shift concurrently.Objectives: The present study was planned and carried out with the aim of assessment of the oral hygiene practice and oral health status among geriatric population.Materials & Methods: This cross sectional study was done among the geriatric population with a view to assess their oral hygiene practice and oral health status. Purposively selected 26 geriatric peoples were interviewed through a structured closed end questionnaire followed by a observational checklist.Results: In this study, it is found that most (84.6%) respondents brush their teeth regularly; more than half (57.7%) respondents brush their teeth twice; most (53.8%) of respondents brush their teeth after awake at morning, and 30.8% respondents brush 2-3 min; half of respondents use tooth brush and tooth paste. In this study, it is found that, respondents aged 70 years have Decayed Missed Filled Teeth (DMFT) (mean ± SD) 5.20 5.72, OHI (mean ± SD) 2.56 01.87. We also found that, respondents have Plaque Index (PI) (mean ± SD) 1.29 1.50, and GI (mean ± SD) 0.20 0.44.Conclusion: Oral health is one of the important components of aging; due to the presence of oral disease, it can affect general health and quality of life of elderly people.KYAMC Journal Vol. 9, No.-2, July 2018, Page 48-52

Published: September 2018

Adaptive and non-adaptive minimal realization (MR) fractional order observers (FOO) for linear time-invariant systems (LTIS) of a possibly different derivation order (mixed order observers, MOO) are studied in this paper. Conditions on the convergence and robustness are provided using a general framework which allows observing systems defined with any type of fractional order derivative (FOD). A qualitative discussion is presented to show that the derivation orders of the observer structure and for the parameter adjustment are relevant degrees of freedom for performance optimization. A control problem is developed to illustrate the application of the proposed observers.

A benchmark of different measurement techniques is presented to characterize the dynamic response of a synthetic jet actuator working in compressible regime. The setup involves a piston-based synthetic jet, as well as the benchmarked measurements are hot-wire, cold-wire, Laser Doppler Anemometry, pressure transducer, and Schlieren visualization. Measured flow temperatures range from 20 °C to 150 °C, pressure ranges from 0.5 atm to 4 atm, and velocity are up to 300 m/s. The extreme values of these ranges are reached in an oscillating fashion at a frequency ranging from 30 to 100 Hz. The measurements are pointing out the limitation of cold-wire measurements, due to its high thermic inertia. The results show consistency in the velocity measurements, within 10% in the worst case, between all measurement techniques and the errors are traced back to the calibration ranges, whose sensitivity is also studied.

The traditional machine tool design method with metal materials makes large-scale moving structures very heavy, which seriously impacts dynamic performance and results in significant energy consumption. Using sandwich structures of composite materials to replace metal materials is an important strategy for lightweight large-scale moving structures. However, this kind of substitution is generally believed to be difficult because foam-filled sandwich structures usually show nonlinear characteristics and must balance the moving mass, material costs, and structural stiffness. In the present study, we proposed a design optimization approach for a large-scale moving framework in a large 5-axis machining center (L5AMC) considering large dimensions in the x, y, and z work space and high machining speed with the aim of minimizing the displacements of the milling head. An improved approach, named the 3-step design optimization, was executed to obtain the optimum framework structures to solve the contradiction between the moving mass, material costs, and structural stiffness. This approach was based on multi-objective optimization and finite element analysis. The structural stiffness of the framework after optimization increased by 89% compared with before optimization although the mass increased by 6% and the material costs increased by 9%. A finite element simulation under four given operational loads showed that the displacements of the milling head were all less than the design requirement of 0.25 mm. The results indicated that the proposed 3-step design optimization approach for the optimal design of a large-scale moving framework was feasible and successful. A 40 m × 6 m × 4 m L5AMC prototype was manufactured, and the actual verification results indicated that the large-scale moving framework fully met the design requirements of the L5AMC and reduced energy consumption.

Resveratrol (3,5,4′-trihydroxy-trans-stilbene) belongs to polyphenols’ stilbenoids group, possessing two phenol rings linked to each other by an ethylene bridge. This natural polyphenol has been detected in more than 70 plant species, especially in grapes’ skin and seeds, and was found in discrete amounts in red wines and various human foods. It is a phytoalexin that acts against pathogens, including bacteria and fungi. As a natural food ingredient, numerous studies have demonstrated that resveratrol possesses a very high antioxidant potential. Resveratrol also exhibit antitumor activity, and is considered a potential candidate for prevention and treatment of several types of cancer. Indeed, resveratrol anticancer properties have been confirmed by many in vitro and in vivo studies, which shows that resveratrol is able to inhibit all carcinogenesis stages (e.g., initiation, promotion and progression). Even more, other bioactive effects, namely as anti-inflammatory, anticarcinogenic, cardioprotective, vasorelaxant, phytoestrogenic and neuroprotective have also been reported. Nonetheless, resveratrol application is still being a major challenge for pharmaceutical industry, due to its poor solubility and bioavailability, as well as adverse effects. In this sense, this review summarized current data on resveratrol pharmacological effects.

The aim of this paper is to compare outcomes between high-dose-rate interstitial brachytherapy (HDR-BT) monotherapy and image-guided intensity-modulated radiotherapy (IG-IMRT) for localized prostate cancer. We examined 353 HDR-BT and 270 IG-IMRT patients. To reduce background selection bias, we used the method of inverse probability treatment weighting (IPTW) with propensity scores. The actuarial five-year biochemical failure-free survival rates were 92.9% and 96.7% (p = 0.1847; p = 0.077 in IPTW) for HDR-BT and IG-IMRT, respectively; they were 100% and 95.8% (p = 0.286) for the low-risk group, 95.6% and 92% (p = 0.42) for the intermediate-risk group, 90.4% and 84.9% (p = 0.1059; p = 0.04 in IPTW) for the high-risk group, and 87.1% and 89.2% (p = 0.3816) for the very-high-risk group. In the assessment of accumulated incidences of grade ≥ 2 toxicity (Common Terminology Criteria for Adverse Events version 4.0) at five years, HDR-BT monotherapy showed higher genitourinary toxicity (11.9%) than IG-IMRT (3.3%) (p < 0.0001). The gastrointestinal toxicity was equivalent for HDR-BT (2.3%) and IG-IMRT (5.5%) (p = 0.063). No Grade 4 or 5 toxicity was detected in either modality. HDR-BT showed higher genitourinary toxicity than IG-IMRT. HDR-BT and IG-IMRT showed equivalent outcomes in low-, intermediate-, and very-high-risk groups. For high-risk patients, HDR-BT showed potential to improve prostate-specific antigen (PSA) control rate compared to IG-IMRT.

Published: September 2018

The catalytic conversion of glycerol to value-added propanols is a promising synthetic route that holds the potential to overcome the glycerol oversupply from the biodiesel industry. In this study, selective hydrogenolysis of 10 wt% aqueous bio-glycerol to 1-propanol and 2-propanol was performed in the vapor phase, fixed-bed reactor by using environmentally friendly bifunctional Pd/MoO3-Al2O3 catalysts prepared by wetness impregnation method. The physicochemical properties of these catalysts were derived from various techniques such as X-ray diffraction, NH3-temperature programmed desorption, scanning electron microscopy, 27Al NMR spectroscopy, surface area analysis, and thermogravimetric analysis. The catalytic activity results depicted that a high catalytic activity (>80%) with very high selectivity (>90%) to 1-propanol and 2-propanol was obtained over all the catalysts evaluated in a continuously fed, fixed-bed reactor. However, among all others, 2 wt% Pd/MoO3-Al2O3 catalyst was the most active and selective to propanols. The synergic interaction between the palladium and MoO3 on Al2O3 support and high strength weak to moderate acid sites of the catalyst were solely responsible for the high catalytic activity. The maximum glycerol conversion of 88.4% with 91.3% selectivity to propanols was achieved at an optimum reaction condition of 210 ∘ C and 1 bar pressure after 3 h of glycerol hydrogenolysis reaction.
