Authors: Vázquez Miguel A. , Vázquez A Blanca P
Published: October 2018

Las radiaciones ultravioleta son radiaciones electromagnéticas con longitudes de onda entre 100 y 400 nanómetros. En cantidades bajas apropiadas, las radiaciones ultravioleta son beneficiosas para la salud y desempeñan una función esencial en la producción de vitamina D. Sin embargo, la exposición excesiva a ellas se relaciona con diferentes tipos de cáncer cutáneo, envejecimiento acelerado de la piel, cataratas y otras enfermedades oculares. En el presente estudio se presentan los resultados del análisis de la radiación total de ultravioleta tipo B, medidos en la estación de San Lorenzo, Paraguay y operada por la Facultad de Ciencias Exactas y Naturales de la Universidad Nacional de Asunción. El periodo del estudio es de junio 1996 a junio de 1998. Los resultados de éste, muestran que los valores mínimos de la radiación tipo B ocurren en invierno, alcanzando un valor medio mensual de 182 mW/m2 en junio, y los valores máximos se registran en el verano llegando alcanzar valor medio mensual de hasta 1029 mW/m2 en enero.

Published: October 2018

The Belagri Hotel and Convention Sorong merupakan perusahaan jasa yang bergerakdibidang penyediaan jasa penginapan, makan dan minum serta fasilitas lain. Perusahaanmenerapkan sistem Activity Based Costing adalah metode penentuan harga yang menelusur biaya ke aktivitas, kemudian ke produk. Metode Activity Based Costing dinilai lebih akurat dalam membebankan biaya overhead kepada produk karena menggunakan lebih dari satu cost driver. Sehingga biaya overhead yang dialokasikan akan lebih proporsional. Tetapi dalam penerapan Activity Based Costing System (ABC) pada perusahaan ada beberapa biaya yang dapat menimbulkan aktivitas tidak dimasukkan dalam penentuan harga pokok produksi kamar. Hasil penelitian menunjukkan terdapat selisih harga yang lebih tinggi dari penetapan harga manajemen hotel dengan hasil perhitungan yaitu, untuk kamar Superior sebesar Rp 7.894, untuk kamar Deluxe sebesar Rp 10.373, untuk kamar Premier sebesar Rp 12.676, untuk kamar Junior Suite sebesar Rp 32.839, untuk kamar Executive Suite sebesar Rp 53.720, dan untuk kamar President Suite sebesar Rp 406.069.

Authors: Rumalutur Sonny
Published: October 2018

Penelitian ini membahas tentang langkah efisiensi yang dilakukan PT PLN (Persero) Area Sorong adalah karena mulai terjadinya krisis energi sehingga harga bahan bakar minyak di tingkat internasionalpun terus meningkat. Hal ini menyebabkan PT PLN harus melakukan efisiensi di segala sektor, dan yang paling utama adalah di sektor penyediaan tenaga listrik. Sehingga perlu menekan susut tegangan seminimal mungkin, baik susut teknik maupun non teknik. Penekanan susut tegangan dilakukan dengan mengambil data perbandingan di setiap rumah saat menggunakan Tap Konektor dan Joint Press Konektor dan dari hasilnya susut tegangan saat menggunakan Tap Konektor adalah sebesar 28,78 % dan susut tegangan saat menggunakan Joint Press Konektor adalah sebesar 11,05 %. Hal ini menunjukkan bahwa penggunaan Joint Press Konektor lebih efisien karena dapat menurunkan susut tegangan sebesar 17,73 %.
ANALISIS PENGARUH KETIDAKSEIMBANGAN BEBAN TERHADAP ARUS NETRAL DAN LOSSES PADA TRANSFORMATOR DISTRIBUSI DI PT PLN (PERSERO) AREA SORONG
Authors: Tobi Markus Dwiyanto
Published: October 2018

PT PLN (Persero) Area Sorong adalah perusahaan yang bertugas melistriki wilayah kota sorong dan sekitarnya. Ketidakseimbangan beban pada suatu sistem distribusi tenaga listrik selalu terjadi dan penyebab ketidakseimbangan tersebut adalah pada beban – beban satu fasa pada pelanggan jaringan tegangan rendah. Akibat ketidakseimbangan beban tersebut timbullah arus di netral trafo. Arus yang mengalir di netral trafo ini menyebabkan terjadinya losses (susut), yaitu susut akibat adanya arus netral pada penghantar netral trafo dan losses akibat arus netral yang mengalir ke tanah. Maka dari itu dibuatlah sebuah analisa dengan menggunakan metode perbandingan dengan cara mengukuran beban pada saat sebelum dilakukan pekerjaan penyeimbangan beban dan dibandingkan dengan pada saat sesudah dilakukan pekerjaan penyeimbangan beban. Penyeimbangan beban ini dilakukan dengan cara memindahkan sebagian beban di fasa yang berbeban tinggi ke fasa yang berbeban lebih rendah sehingga dihasilkan beban fasa yang seimbang. Hasil analisa menunjukan bahwa pada saat sesudah dilakukan pekerjaan penyeimbangan beban, nilai arus netral di penghantar netral trafo dan arus netral yang mengalir ke ground lebih kecil sehingga susut yang dihasilkan lebih kecil dibandingkan pada saat sebelum dilakukan pekerjaan penyeimbangan beban.

Background Aim of this research is to assess the efficacy and safety of tocilizumab (TCZ) in combination with methotrexate (MTX) in Indonesian patients with moderate to severe active rheumatoid arthritis (RA) who have an inadequate response to non-biologic DMARDs.Methods This was a interventional, prospective, single arm, multicenter, study in Â Indonesian male or female patients aged â‰¥ 18 years old, with a diagnosis of RA for > 6 months based on ACR 1987 revised criteria with moderate to severe disease activity (DAS28 score > 3.2) after â‰¥ 12 weeks of non-biologic DMARDs treatment. The treatment consisted of tocilizumab, 8 mg/kg, intravenous (IV), every 4 weeks for a total of 6 infusion in combination with oral MTX (10âˆ’25 mg) every week. Efficacy was assessed based on the percentage of patients achieving low disease activity state (DAS28 < 3.2), percentage of patients achieving reduction > 1.2 point of DAS28, percentage of patients achieving remission (DAS28 < 2.6), and percentage of patients with ACR20, ACR50, and ACR70 responses. Descriptive statistics will be used for presentation of results.Results 100% patients reached low disease activity (DAS28 â‰¤ 3.2) at last study visit (week 24) and clinically significant improvement (reduction at least 1.2 units) at every visit in DAS28, both for ITT or PP patients. Remission (DAS28 < 2.6) was observed in 82.1% (ITT patients) and 93.1 % (PP patients) on last study visit. ACR20, ACR50, and ACR70 were achieved in 20%, 34%, and 34% (ITT patients), and 7%, 24%, and 62% (PP patients) on week 24. There were 3 out of 39 patients (7.69%) with adverse events (AE) and serious adverse events (SAE) that resulted in discontinuation of TCZ treatment, consisting of 1 patient with SAE of sepsis ec acquired community pneumonia, 1 patient with SAE of pneumonia tuberculosis, and 1 patient with AE of candidiasis. Most common adverse events were hepatic dysfunction (30.7%), hypercholesterolemia (23.1%), followed by arthralgia (20.5%) Twelve percent of patients needed dose modification due to elevated liver enzyme (elevated ALT/SGPT level).Conclusion Tocilizumab seems to be efficacious and likely to have good safety profile in non- biologic DMARD nonresponsive RA patients of PICTURE INA study.

Puntura arteriosa e dolore: l’efficacia delle tecniche analgesiche. Una revisione della letteratura
Authors: Barresi F. , Ferrari M.
Published: October 2018

Introduction: Arterial puncture is a procedure that allows to assess the patient’s state of ventilation, their metabolic balance and their glycemic levels. An unfortunate feature of this technique is that it often causes pain, in fact the arterial wall, unlike the venous wall, is particularly rich in pain receptors. Although numerous studies invite us to use analgesic techniques, this procedure is recognised by the patient as one of the main sources of concern and one of the most unpleasant experiences of hospitalisation. The advantages offered by analgesic techniques include both the reduction of the perceived pain of the patient and the prevention of common situations such as the patient holding their breath or hyperventilating which could cause an alteration of blood gas flow values. The purpose of the following study is to evaluate, through a review of the literature, the effectiveness of analgesic techniques for the management of pain associated with arterial puncture, performed in adult patients. Materials: Bibliographic research has been carried out which has provided for consultation of the Cinahl, Embase and Pubmed databases, using a research question formulated using PIO methodology. Results: The analgesic techniques that emerged from the present literature review concern the reduction of needle size, cryoanalgesia and pharmacological analgesia. The results showed that the reduction of the needle gauge can be a valid analgesic technique for patients who do not require electrolyte evaluation. Cryoanalgesia was effective in reducing pain, while discordant results emerged regarding the administration of pharmacological analgesics prior to arterial puncture. Conclusions: The analgesic techniques identified were well received, however they are still infrequently used. Further studies would be needed to clarify their real effectiveness and to adequately define how to use them.

Introduction: Effective treatment of obstructive sleep apnoea syndrome (OSAS) with continuous positive air pressure (CPAP) may reduce morbidity and mortality, but adherence rates are low without a clear consensus of the causes. Objective: The aim of the literature review was to identify the cognitive factors, barriers and facilitators related to therapeutic adherence to treatment with CPAP in patients with OSAS. Results: Selected studies show that the factors that most affect adherence are: socio-economic, associated therapies, pathology and health services. A disadvantaged socio-economic status, side-effects related to the interface, the presence of co-morbidities, poor patient knowledge and the limited ability to guarantee valid educational pathways are considered the greatest barriers to a lack of access to treatment. Conclusions: Understanding the predictive factors and those that impede therapeutic adherence in patients with OSAS under treatment with CPAP, can help healthcare professionals to choose effective care interventions. Acting on the factors influencing patient choices, such as knowledge, skills, locus of control and personal values, improves the level of self-efficacy and supports adherence to treatment.

Introduction: In Italy about 3.5 million women and 1 million men are affected by osteoporosis. This is an emerging condition resulting from the aging of the population, which affects about 50% of women after age 70, following the onset of menopause and subsequent physical changes. The need was felt, by women, for more information about this pathology in order to implement valid preventive strategies, needs whose satisfaction is part of advanced nursing skills. Objectives: assessment of knowledge related to preventive strategies and implementation of educational interventions aimed at improving them. Materials and methods: The recruited sample is made up of patients belonging to Gynaecology clinics at two Local Health Authorities in the province of Naples and Caserta, between the ages of 40 and 70, who underwent a preventive intervention aimed at increasing their knowledge on the subject of osteoporosis, subsequently assessed through the aid of a questionnaire created ad hoc based on data collected in the literature. Results: It emerged the educational intervention implemented, in which 54 women participated, was considered useful, in all its aspects, in good percentage. Conclusions: The study shows the need to implement educational interventions aimed at promoting the prevention of this disease. The exercise of these activities is a part of nursing skills and therefore the educational function of the nurse has assumed a complementary value of the function of assistance and care.

Introduction: Secondary lymphoedema represents a potential complication of axillary lymphadenectomy for breast cancer. lymphoedema related to breast cancer, requires targeted interventions based on the best scientific evidence in order to motivate patients to observe behaviour that will reduce the risk. The aim of the study is to structure an educational intervention and evaluate the knowledge of patients who have undergone lymph node removal in the prevention of lymphoedema. Materials and methods: Prospective cohort study, conducted between May and August 2014 on patients undergoing axillary lymphadenectomy for breast cancer. The patients were divided into three cohorts, the first group received the educational intervention, the second group received routine information while the third group consisted of patients being treated for lymphoedema. Results: the sample consists of 45 patients, 57.8% of the sample knew the preventive measures for lymphoedema, 13.3% of patients did not receive any information, more than 20% of the sample identifies the nurse as the main source of information. Discussion: The group of patients given the educational intervention, started preoperatively, have more knowledge about prevention, are more aware of the risks compared with the group that received the routine information while patients treated for lymphoedema have good knowledge. Conclusion: Patient management capacity improves significantly as the level of information received increases. The educational intervention begins in the perioperative phase, nurses must favour the process of self-care of the patients by improving their knowledge and skills in the prevention of lymphoedema.

Introduction: There are various types of advanced dressings used on the market for the treatment of surgical wounds and for the containment of related complications. However it is not clear which is the most appropriate in relation to the type of wound. For this purpose, bibliographic research was carried out to find evidence in the literature on the correct use of dressings in order to favour the healing process of the surgical wound. Methods: Bibliographic research was carried out which included consultation of the Cochrane Library, PubMed and CINAHL databases. NICE guidelines and documents found by Google Scholar were consulted. Results: Articles with a sample of adult patients undergoing any surgery were selected. The use of advanced dressings has mainly reduced the incidence of complications such as infections, blisters, seromas and pain. Conclusions: The results show that advanced dressings are indicated in the treatment of wounds that heal by delayed primary closure, by secondary intention, for dirty or infected wounds. Traditional dressings, on the other hand, are indicated for wounds that heal by primary intention.

Published: October 2018

An in vitro propagation protocol has been established for yardlong bean (Vigna unguiculata ssp. sesquipedalis L. Walp. Verdc.) using shoot tip, nodal and leaf segment explants of the superior plant type obtained from crossing of two selected parental lines. Explants were cultured on MS medium supplemented with different concentrations and combinations of BAP, Kn and Zeatin and NAA, IAA, IBA. The highest percentage (86) of shoot regeneration with maximum shoots per culture (12 ± 0.43) was obtained from nodal explants on MS medium supplemented with 0.5 mg/l BAP and 0.2 mg/l NAA. Addition of 10% coconut water and 75 mg/l urea to the medium enhanced shoot multiplication and elongation, respectively. Rooting of the regenerated shoots was optimum on half-strength MS enriched with 3.0 mg/l IBA. Regenerated plantlets were successfully acclimatized. After acclimation, plantlets were transplanted in the experimental field where the survival rate was 80%.

Effects of nano-ferric oxide on quality, quantity and antioxidant properties of essential oil components in Carum copticum (L.) Link
Authors: Kazemi Mohsen
Published: October 2018

The effect of exogenous application of nano-ferric oxide (50 and 100 mg/l) in early flowering stage on components of essential oils (EOs) of Carum copticum (L.) Link was evaluated. EO extracted by hydrodistillation from Iranian C. copticum was characterized by means of GC/MS. The nano-ferric oxide application increased limonene, γ- terpinene, cis-limonene oxide, thymol, carvacrol and decreased α-thujene, α-pinene, β-pinene and p-cymene concentration. The EO was also subjected to evaluation for antioxidant properties. Thymol, γ-terpinene and carvacrol possessed the highest antioxidant properties among the major components. C. copticum EO exhibited a higher activity in each antioxidant system with a special attention to β-carotene bleaching test and reducing power. The TLC-bioautography screening and fractionation resulted in the separation of the main antioxidant compounds which were identified as thymol, γ-terpinene and carvacrol.

Published: October 2018

The genetic diversity and structure of 4 wild population and 2 ex situ conserved population of Hopea chinensis (Merr.) Hand.-Mazz were analyzed and compared by ISSR marker method. Fifty eight bands were amplified from total genomic DNA with 10 primers in which there were 51 polymorphic, the percentage of polymorphic bands of populations ranged from 53.45 to 79.31, with an average value of 69.82, indicating the presence of high genetic diversity. However, the percentage of polymorphic band, Nei’s diversity index (He) and Shannon information index (I) of wild populations (86.21, 0.3636 and 0.5232, respectively) were higher than those of ex situ conservated populations (77.59, 0.3153 and 0.4597, respectively), which meant that ex situ conservations of Hopea chinensis had a narrow genetic diversity. Population structure analysis revealed that genetic variation of Hopea chinensis was 0.0373, so the genetic differentiation was 3.73% among populations, and 96.27% in populations. Furthermore, the strong gene flow (Nm = 12.8896) would be the main reason of limited population differentiation. It concluded that ex situ population had not yet fully covered the entire genetic diversity of Hopea chinensis.

A series of phenolic compounds containing 2-phenylphenol (PPE), bisphenol A (BPA), 4-isopropylphenol (IPE), 4-methylphenol (ME) and phenol (PE) were selected to investigate their major influence factors for their adsorption on graphene oxide (GO) and reduced graphene oxide (RGO) by studying their adsorption isotherms and kinetics. It was found that the adsorption of all tested phenols fitted well with the Freundlich model. In comparison, the adsorption ability of RGO with a stronger π-π interaction was superior to GO, which was confirmed by using naphthalene probe measurements. The thermodynamic characteristics, by studying the effect of the adsorption temperatures (298, 313 and 333 K), demonstrated that the adsorption process was spontaneous, exothermic and entropy-decreasing. The chemical structures of the phenols also affected their adsorption on GO and RGO. It was found that the adsorption capacities of phenols were, in order, PE (0.271 mmol g−1 on GO and 0.483 mmol g−1 on RGO) < ME (0.356 and 0.841 mmol g−1) < IPE (0.454 and 1.117 mmol g−1) < BPA (0.4 and 1.56 mmol g−1) < PPE (0.7 and 2.054 mmol g−1), which depended on the π-electron density of the benzene ring by means of a density functional theory (DFT) calculation. Undoubtedly, the reduction of GO and an increase in π-electron density on the chemical structures of phenols facilitated the adsorption.

Published: October 2018

This article presents an advanced dual chaotic watermarking scheme to improve information security. To ensure confidentiality in digital image transmission, a secure dual watermarking scheme is proposed by applying the chaotic logistic system and hyper-chaotic dynamical system. Chaotic watermarking was conducted in the spatial domain, where suboptimal secure hashing with a variable length was selected in preprocessing stages. The secret key was generated by the chaotic sequence for pixel shuffling using a chaotic logistic map, so that a controlled amount of distortion was inserted into the host digital image. Watermarking was proceeded after the chaotic watermark had been embedded into the shuffled image. To strengthen the security, the hyper-chaotic system was used to generate chaotic blocks for block scrambling in order to achieve dual chaotic watermarking. Characteristics analysis was conducted for multiple examples in both spatial and frequency domains. Potential effects induced by the chaotic driving parameter on processing time and integrity authentication of chaotic dual watermarking were also analyzed in detail.

Authors: Oschatz Martin , Walczak Ralf
Published: October 2018

This special issue of C—Journal of Carbon Research is dedicated to “Functional Nanoporous Carbon-Based Materials”. It contains contributions reporting on the synthesis of nanoporous carbons for the adsorption of proteins, their applications in electrochemical energy storage/conversion, and on the characterization/modification of their surface chemistry. Nanoporous carbon-based materials are widely researched, but at the same time, the field is still full of unutilized potential. The atomic construction of the carbon framework, pore sizes, pore geometries, presence of heteroatoms, particle size and shape, and many other “internal screws” are available; in the end, the high potential of carbon-based materials will only be fully explored if the interplay of these crucial factors is precisely controlled. This article is a summary of what we consider important for future targeted improvement of porous carbon nanomaterials for energy and environmental applications.

Published: October 2018

Transitions is today’s debate in almost all topics both in academia and practice. Energy transitions among others, have received relatively more attention, due to the global demand for increasing energy efficiency and lowering environmental impacts. In recent decades, energy management systems, through implementing energy management programs and related practices within industrial companies, have played a vital role in enhancing industrial energy efficiency performance levels. However, still there are problems at very first step of energy management program installation, which is decision-making. Despite market and non-market failures, lack of information, inadequate knowledge, the consequent increase in the perception of risk and uncertainty can be addressed as potential reasons for mentioned problems. Another essential reason can be explained through how an energy program is characterized by people who are attending at an energy-related decision desk. Keeping in mind that allocation of the budget for any investment should not only have financial conformation, but also a strategic value for the company, this paper aims to discuss the impacting parameters on industrial energy-related decision-making and behavior patterns with respect to the critical role of industrial energy management systems.

Published: October 2018

This paper proposes an intelligent battery management system (BMS) implementing two large Vanadium Redox Battery (VRB) flow batteries in a master-slave mode to provide grid-level energy storage for a wind-solar hybrid power system. The proposed BMS is formulated to effectively meet a predetermined power dispatch formulated based on forecasted wind and solar data while incorporating features like peak shaving and ramp rate limiting. It is compared to a single battery module operated system to showcase the advantages of the proposed intelligent dual battery module in terms of appreciable reduction in battery size and costs while exhibiting improved lifecycle performance. The battery size is optimized based on heuristic optimization algorithms and modelled in Matlab/Simulink environment. An intelligent fuzzy-based BMS is used to control the dual VRB model to ensure optimized power sharing between batteries. The simulations were carried out and an in-depth economic analysis conducted to analyze the costs and other financial metrics of the hybrid project. Results proved the advantages of the dual battery with the proposed BMS and fortify that the introduction of time-based tariffs and other incentives will further make investments in VRB highly attractive for renewable applications.
GIS-Based Methodology for Evaluating the Wind-Energy Potential of Territories: A Case Study from Andalusia (Spain)
Authors: Díaz-Cuevas Pilar
Published: October 2018

In recent years, Spain, in an effort to meet European Union (E.U.) targets, has been developing different strategies to promote the installation of renewable energy plants. In this regard, evaluating territories to assess their potential and thus identify optimum sites for the installation of energy-generating facilities is a crucial task. This paper presents a comprehensive geographic information system (GIS)-based site-selection methodology for wind-power plants in the province of Córdoba, which has hitherto been regarded as unsuitable for this sort of facility owing to the lack of wind resources. Three scenarios have been set out, each of which presents a different set of restrictions. Scenario 2 applies the most stringent restrictions in the specialized literature, and finds no suitable areas for the installation of wind-energy plants. However, Scenario 1, which applies the least stringent restrictions, and Scenario 3, which applies the same restrictions currently in force for other wind turbines already in operation in Andalusia, have led to the identification of several areas that could a priori be considered suitable and now need more detailed analysis. The results illustrate the convenience of undertaking multiscenario analyses.

Published: October 2018

This contribution considers an improved control scheme for three-phase two-stage grid-tied photovoltaic (PV) power systems based on integral sliding mode control (ISMC) theory. The proposed control scheme consists of maximum power point tracking (MPPT), DC-Link voltage regulation and grid current synchronization. A modified voltage-oriented maximum power point tracking (VO-MPPT) method based on ISMC theory is proposed for design of an enhanced MPPT under irradiation changes. Moreover, a novel DC-Link voltage controller based on ISMC theory is proposed to achieve good regulation of DC-Link voltage over its reference. To inject the generated PV power into the grid with high quality, a voltage-oriented control based on space vector modulation (SVM) and ISMC (VOC-ISMC-SVM) has been developed to control the grid current synchronization. Numerical simulations are performed in a MATLAB/SimulinkTM (R2009b, MathWorks, Natick, MA, USA) environment to evaluate the proposed control strategy. In comparison with conventional control schemes, the developed control strategy provides an accurate maximum power point (MPP) tracking with less power oscillation as well as a fast and an accurate DC-Link regulation under varying irradiation conditions. Moreover, the transfer of the extracted power into the grid is achieved with high quality.
Fixed Frequency Sliding Mode Control of Power Converters for Improved Dynamic Response in DC Micro-Grids

Published: October 2018

The rapid decrease in conventional energy resources and their harmful impact on the environment has brought the attention of the researchers towards the use of renewable energy technologies. The renewable energy systems are connected to Direct Current (DC) micro-grids via power electronic converters where the load conditions are unknown and network parameters are uncertain. These conditions call for the use of robust control techniques such as Sliding Mode Control (SMC) in order to regulate the grid voltage. However, SMC has a drawback of operating the power converter at variable switching frequency which results in degrading the power quality. This paper introduces a fixed frequency sliding mode controller that does not suffer from this predicament. A novel double integral type switching manifold is proposed to achieve voltage regulation of a DC micro-grid, in the presence of unknown load demands and un-modeled dynamics of the network. Rigorous mathematical analysis is carried out for the stability of the closed loop system and the technique is experimentally validated on position of a DC micro-grid using a specially designed test rig. For benchmarking purposes, a conventional Proportional Integral (PI) controller is also implemented. An improvement of 2.5% in rise time, 6.7% in settling time and reduction of voltage dip by 31.7% during load transaction is achieved as compared to the PI controller. The experiment confirms the hypothesis that fixed frequency SMC shows better performance than its counterpart in the phase of introduced disturbances.
