Analytical Development and Validation of a Stability-Indicating Method for the Estimation of Impurities in Budesonide Respules Formulation
Authors: Rasheed Anas , Ahmed Osman
Published: June 2017

A short selective, precise, accurate and sensitive stability-indicating LC-MS/MSn method was developed for the quantitative determination of process-related impurities and degradation products of Budesonide in pharmaceutical respules formulations. During the stress study, the degradation products of Budesonide were well-resolved from Budesonide and its impurities and the mass balances were found to be satisfactory in all the stress conditions, thus proving the stability-indicating capability of the method. The developed method was validated as per ICH guidelines with respect to specificity, linearity, limit of detection and quantification, accuracy, precision, ruggedness and robustness. During the stability analysis of the drug product, all known impurities were detected by the above stability-indicating method. The flow rate was 0.8 ml/min and effluent was monitored at 247nm. Retention time was found to be 17.329±0.75 min and18.439±0.65 min of epimers (22R and 22S)respectively. The LOD and LOQ values for were found to be 0.20936 (μg/ml) and 0.6344 (μg/ml) respectively.
An efficient method to improve the production of methane from anaerobic digestion of waste activated sludge
Authors: Li Xiaolan , Xu Xueqin , Huang Shansong , Zhou Yun , Jia Haijiang
Published: June 2017

Methane production from waste activated sludge (WAS) anaerobic digestion is always low due to slow hydrolysis rate and inappropriate ratio of carbon to nitrogen (C/N). In this work, a novel approach, i.e., co-digestion of WAS and tobacco waste (TW) using ozone pretreatment, to greatly enhance the production of methane is reported. Experimental results showed the optimal C/N and ozone dosage for methane production was 24:1 and 90 mg/g suspended solids, and the corresponding methane production was 203.6 mL/g volatile suspended solids, which was 1.3-fold that in mono-WAS digestion. Further investigation showed the co-digestion of WAS and TW was beneficial to the consumptions of protein and cellulose; also, the presence of ozone enhanced the disruption of organic substrates and production of short chain fatty acids, which provided sufficient digestion substrates for methane generation. Analysis of microbial community structure suggested that members of the phyla Bacteroidetes and Firmicutes were the dominant species when ozone pretreatment was applied. The findings obtained in this work might be of great importance for the treatment of WAS and TW.
A controlling fejlődéstörténete, helye és szerepe a gazdálkodó szervezetekben
Authors: Sütő Dávid
Published: June 2017

A controlling kialakulása a 20. század elejére tehető, így már egy évszázados töretlen tudományterületi fejlődés tudhat maga mögött, és alkalmazásra került mind a pénzügyek, gyártás-termelés, kereskedelem értékesítés területein. A pénzügyi számvitelen belül kialakultak a költségek és teljesítmények tervezéséért, elszámolásáért felelős tevékenységek, amelyet a vezetői számvitel, mint a menedzsment folyamatosan növekvő információigényét kielégítő terület fogott össze. Az operatív működésen túl a növekvő és diverzifikálódó vállalatoknál a controlling kiterjedt a stratégiai vezetés szintjére is. A controlling tevékenység fő fókusza a 21. századi vállalatoknál a szervezeti teljesítmény javítása. Korábban voltak különbségek a controlling német és angolszász irányzatai között. Míg a német megközelítés szerint a controlling egy eszközrendszer, amely segítségével rendelkezésre állnak a vezetői döntéshozatalhoz szükséges információk, ezek alapján pedig megvalósíthatók a tervezés, ellenőrzés, és controll tevékenységek. Ezen túl a német irányzat szerint a controlling tevékenységért külön szervezeti egység a felelős. Ezzel szemben az angolszász felfogás szerint a controlling a vezetés része, és a vezetők feladata az erőforrások hatékony allokálása, az ún. „management controll”, a tervezés és controll feladatok egyszerre történő ellátása. Bár azzal kapcsolatban, hogy „hol a helye” a controllingnak a vállalat szervezeti keretein belül, felfedezhetjük a különbségeket, a két irányzat között. Tényként kijelenhető azonban, hogy a vezetés és a controlling egymástól elválaszthatatlan, mind a két a terület együttes célja a vállalti teljesítmény növelése.
Innovációs projektek tapasztalatai az „európai paradoxon” tükrében
Authors: Tóthné Kiss Anett
Published: June 2017

A gazdaság fejlődésének, a vállalatok hosszú távon nyújtott magas színvonalú teljesítményének meghatározó tényezője lehet a vállalati innováció. A 2000-es évek után az Európai Unió pozíciója nem javult a nemzetközi innovációs versenyben, bár a lisszaboni célkitűzéseket teljesítve 2010 után javuló tendenciát mutat, még mindig lemarad az élmezőnytől K+F+I tekintetében. A folyamat mögött részben a gyorsan iparosodó fejlődő országok egy részének a gyors K+F+I felzárkózása áll, részben pedig Európa nemzeti innovációs rendszereinek viszonylag lassú intézményi fejlődése. A relatív európai lemaradás magyarázatára gyakran alkalmazott „európai paradoxon” jelenség azonban módszertani okok miatt nem egyértelmű. A kutatás során először a kiválasztott területek innovációs pozíciói képezik a vizsgálat tárgyát a nemzetközi innovációs versenyben, majd az Európai Unió gyengébb összesített teljesítményének egyik közkeletű szakmai magyarázata, az „európai paradoxon”. A cikkben ennek feltételezett jelenléte, esetleges okai, körülményei számos empirikus kutatással ellentétben vállalati vezetőkkel készített interjúk alapján kerülnek ismertetésre.

A műszaki felsőoktatásba érettségi után bekerülő hallgatók már rendelkeznek valamilyen elképzeléssel a mérnöki szakmáról, a helyes mérnöki magatartásról, és a saját alkalmasságukról. Az első felmérésem kérdései a hallgatói tanulmányok kezdetekor ezekre a témákra irányultak. A második felmérést a félév végén készítettem, amikor már a kötelezően oktatott mérnöki etika tantárgy ismereteit elsajátították. A hallgatói válaszok azt mutatják meg, hogy mennyiben segítette elő ennek a tárgynak az oktatása azt, hogy jobb mérnökké válhassanak a diploma megszerzése után.
O agir democrático numa era de redes digitais
Authors: Coleman Stephen
Published: June 2017

RESUMO

A política contemporânea possui uma qualidade transitória e indeterminada, pairando de forma inquieta entre o centralizado e o em rede, o nacional e o global, o gerenciado e o populista, o analógico e o digital. Práticas políticas antes tomadas como certas começaram a parecer instáveis e modos emergentes de articulação política estão desestabilizando complacências institucionais. Ao longo do século XX, a consolidação de democracias políticas gerou abordagens de rotina à produção, ao processamento e à comunicação de mensagens políticas. Este sistema de comunicação política resultou em relações previsíveis entre elites políticas, mediadores jornalísticos e cidadãos. Como espero ter deixado claro nesta palestra, seria ingênuo supor que simplesmente mover a comunicação política online irá enriquecer ou degradar as vozes dos cidadãos democráticos. O antigo debate entre o bem e o mal da internet é despropositado e redundante. Porém, se a pressão democrática popular pelo tipo de construção de capacidade cívica que eu elenquei nesta palestra ganhar tração, tecnologias digitais, espaços e códigos podem, realmente, ter um papel significativo em facilitar práticas conducentes a uma democracia mais inclusiva, respeitosa e deliberativa. 

 

ABSTRACT

Contemporary politics has a transitional and indeterminate quality, hovering uneasily between, the centralised and the networked, the national and the global, the managed and the populist and the analogue and the digital. Once taken-for-granted political practices have begun to seem unstable and emergent modes of political articulation are unsettling institutional complacencies. During the course of the twentieth century the consolidation of political democracies generated routine approaches to producing, processing, and communicating political messages. This political communication system resulted in predictable relations between political elites, journalistic mediators and citizens. As I hope I have made clear in this lecture, it would be naïve to assume that simply moving political communication online will either enrich or degrade the voices of democratic citizens. The old debate between Internet-Good and Internet-Bad is pointless and redundant. But if popular democratic pressure for the kind of civic capability-building that I have outlined in this lecture were to gain traction, digital technologies, spaces and codes might indeed play a significant role in facilitating practices conducive to a more inclusive, respectful and deliberative democracy.

Bisfenol (A) una toxina a tener en cuenta en el enfermo renal en hemodiálisis
Authors: Bosch  Panadero Enrique , Mas Fontao Sebastian , Ruiz Priego Alberto , Egido Jesús , González Parra Emilio
Published: June 2017

Muchas toxinas urémicas son originadas como consecuencia del catabolismo proteico por la flora intestinal. El metabolismo de aminoácidos aromáticos origina residuos de tipo fenólico. De estas toxinas, la más estudiada es el p-cresol, que se asocia a la función renal y daño vascular. El Bisfenol A (BPA) es una molécula exógena de características semejantes a estas toxinas urémicas aromáticas. El BPA es un disruptor endocrino estrogénico que se encuentra en latas de conserva, botellas de plástico, resinas epoxi y en algunos dializadores. Esta molécula se acumula en pacientes que tienen deteriorada la función renal. Estudios observacionales han demostrado que una exposición a BPA está vinculada, entre otras muchas, a lesión renal y cardiovascular en los seres humanos; en estudios en animales se ha descrito un vínculo causal. Los riñones con función renal normal excretan rápidamente BPA, pero una excreción insuficiente en pacientes con ERC da lugar a la acumulación del BPA en el organismo.

Application of the SHS-GC-FID method and HPLC-DAD method in the prediction of the shelf-life of gluten-free cookies
Authors: Sakac Marijana , Pezo Lato , Jovanov Pavle , Nedeljkovic Natasa , Mandic Anamarija , Pestoric Mladenka , Misan Aleksandra
Published: June 2017

The aim of this study was to compare the sensitivity of two analytical methods for the prediction of the shelf-life of unpacked and packed gluten-free rice?buckwheat cookies kept at ambient (23?1?C) and elevated (40?1?C) temperature during storage, namely the static headspace gas chromatographic method with flame ionisation detection (SHS-GC-FID) for volatile saturated aldehydes (propanal (C3), pentanal (C5), hexanal (C6), heptanal (C7) and octanal (C8)) and the HPLC method for malondialdehyde (MDA) determination. Both methods resulted in obtaining the same end-points of cookie shelf-life, i.e., 3 and 5 months for unpacked and packed cookies kept at elevated temperature, respectively, and 11 and 14 months for unpacked and packed cookies kept at ambient temperature, respectively. Two computational approaches, i.e., the second order polynomial (SOP) and artificial neural network (ANN) models, were used accordingly. The calculations of the contents of aldehydes and MDA could be predicted with an overall coefficient of determination of 0.722 using the ANN model compared to 0.312?0.773 for SOP models. According to sensitivity analysis, it might be suggested that the relevant parameter for the prediction of the end-point of cookie shelf-life is the MDA rather than the C3, C5, C6, C7 and C8 content.
A possible underlying mechanism of gastric mucosal ruptures due to resuscitation efforts
Authors: Zivkovic Vladimir , Nikolic Slobodan
Published: June 2017

Introduction. The occurrence of gastric mucosal ruptures during cardiopulmonary resuscitation (CPR) is contributed to extensive gastric distention, either due to mouth-to-mouth resuscitation or the use of a bag and mask, or inappropriate intubation that may lead to gastric hyperinflation, which then creates gastric distension and further promotes gastric rupture. The presented case suggests that there might be another mechanism ? chest compressions during CPR. Case outline. We present a case of an 84-year-old woman who died due to severe chronic ischemic heart disease after unsuccessful resuscitation. The autopsy revealed a presence of several shallow ruptures of gastric mucosa on the lesser curvature, 1?3 cm in length, with surrounding mucosal hemorrhage, and without bleeding in the gastric cavity. Conclusion. Gastric mucosal ruptures could occur due to a combination of two mechanisms: pressure propagation due to chest compression and gastric hyperinflation

OBJECTIVE

We aimed to investigate the differences in clinical characteristics and pharmacological treatment associated with the presence of diabetes in a large cohort of patients with dementia.

RESEARCH DESIGN AND METHODS

A cross-sectional registry-based study was conducted using data from the Swedish Dementia Registry (SveDem). Data on dementia diagnosis, dementia type, and demographic determinants were extracted from SveDem. Data from the Swedish Patient Register and Prescribed Drug Register were combined for the diagnosis of diabetes. Data on antidiabetic, dementia, cardiovascular, and psychotropic medications were extracted from the Swedish Prescribed Drug Register. Logistic regression was used to determine whether the variables were associated with diabetes after adjustment for confounders. In total, 29,630 patients were included in the study, and 4,881 (16.5%) of them received a diagnosis of diabetes.

RESULTS

In the fully adjusted model, diabetes was associated with lower age at dementia diagnosis (odds ratio [OR] 0.97 [99% CI 0.97–0.98]), male sex (1.41 [1.27–1.55]), vascular dementia (1.17 [1.01–1.36]), and mixed dementia (1.21 [1.06–1.39]). Dementia with Lewy bodies (0.64 [0.44–0.94]), Parkinson disease dementia (0.46 [0.28–0.75]), and treatment with antidepressants (0.85 [0.77–0.95]) were less common among patients with diabetes. Patients with diabetes who had Alzheimer disease obtained significantly less treatment with cholinesterase inhibitors (0.78 [0.63–0.95]) and memantine (0.68 [0.54–0.85]).

CONCLUSIONS

Patients with diabetes were younger at dementia diagnosis and obtained less dementia medication for Alzheimer disease, suggesting less optimal dementia treatment. Future research should evaluate survival and differences in metabolic profile in patients with diabetes and different dementia disorders.
¿Negar o reescribir la Hispanidad? Los nacionalismos subestatales ibéricos y América Latina, 1898-1936
Authors: Núñez Seixas Xosé M.
Published: June 2017

Buena parte de la discusión historiográfica acerca del proceso de construcción nacional en la España del siglo XIX ha girado alrededor de la cuestión de la débil nacionalización. Sin embargo, el hecho de que España haya sido un imperio ultramarino hasta 1898, y aun después de esta fecha siempre ha jugado un papel secundario en el debate. En este artículo, y desde una perspectiva que resalta el carácter transnacional de todo nacionalismo, se aborda un aspecto concreto de la interacción entre imperio y construcción nacional en la España de la primera mitad del siglo XX. ¿Hasta qué punto la evolución de la cuestión colonial en el Caribe y Filipinas influyó en el desarrollo del debate territorial entre centralización y descentralización en la España metropolitana?¿Hasta qué punto los emergentes regionalismos y nacionalismos subestatales ibéricos miraron hacia las colonias o las antiguas colonias españolas, qué aprendieron de sus experiencias, y qué relación aspiraban a mantener con esos territorios?

Courtyard Housing in China: Chinese Quest for Harmony
Authors: Zhang Donia
Published: June 2017

The Chinese have lived in single-extended-family courtyard houses in many parts of China for thousands of years. The earliest courtyard house found in China was during the Middle Neolithic period (5000-3000 BCE). The courtyard form signifies Chinese quest for harmony with nature and in social relationships. However, the 20th century was a significant turning point in the evolution of Chinese courtyard houses; this paper provides an overview of this transition. It starts by briefly introducing traditional Chinese courtyard houses and their decline since 1949, it then examines the emergence of new courtyard housing in Beijing and Suzhou since the 1990s, and then it evaluates the new development of Chinese-style courtyard garden villas in/around these two cities since the 2000s, such as Beijing Guantang and Suzhou Fuyuan villa estates. They are explorations of a new way to honour Chinese architectural history and philosophy, meanwhile, incorporating Western interior design principles to meet modern living requirements. This architectural acculturation represents Chinese sustained quest for harmony in their art of living. The paper finally proposes four designs of new courtyard garden houses for future practice.

Plicatura gástrica laparoscópica, control de dos casos post quirúrgico: hormona ghrelina
Authors: Monserrate Cervantes Juan , Maggi Garcés Bertha
Published: June 2017

En la presente investigación se determinan los niveles de ghrelina postquirúrgico, pérdida de peso y variables hemodinámicas, en pacientes con diagnóstico de obesidad mórbida, operados hace cuatro y dos años, de plicatura gástrica. Sólo la ghrelina, hormona producida en el estómago, se ha asociado de manera consistente con el inicio de la ingesta y se la considera una de las principales señales orexigénicas en los modelos animales estudiados y en humanos. Dada la importancia que los trastornos de la ingesta de alimentos, especialmente la obesidad, el conocimiento de los mecanismos de acción de estas señales endocrinas ha tomado mayor importancia, pues podría contribuir al desarrollo de nuevas moléculas que incrementen y mejoren el  arsenal terapéutico para tratar la obesidad. Diversas técnicas se han desarrollado con diferentes resultados y complicaciones. Una nueva técnica con resultados prometedores, la plicatura gástrica (invaginación de la curvatura mayor del estómago, sin cortar,reversible), no tendría las complicaciones del uso de sutura mecánica e implicaría una reducción de los costos. Abstract In the present investigation, the levels of post-surgical ghrelin, weight loss and hemodynamic variables were determined in patients diagnosed with morbid obesity, operated for four and two years after gastric plication. Only ghrelin, a hormone produced in the stomach, has been associated with persistent onset of onset and is considered one of the major orexigenic signals in the animal models studied and in humans. Given the importance of eating disorders, especially obesity, knowledge of the mechanisms of action of these endocrine signals has become more important because it could contribute to the development of new molecules that increase and improve our therapeutic arsenal to treat Obesity. Several techniques have been developed with different results and complications. A new technique with promising results, gastric plication (invagination of the major, uncut, reversible stomach curvature) would not have the complications of mechanical suture use and would imply a reduction in costs.
Philology and the Complex Present

Based on the sketch of a long-range history of philology as textual curatorship, this essay tries to assess its practical value and its epistemological status in a cultural situation which, over the past quarter century, has been profoundly transformed by electronic technology. The assessment includes a critique of the high-flying hopes attached to the digital humanities.
Einfluss von Wildhuftieren auf den Wald seit Langem zu hoch – was tun? (Essay)
Authors: Brang Peter

Impact of wild ungulates on forests too high for too long – what to do? (Essay)

The impact of wild ungulates on forest regeneration has increased in Swiss forests for about five decades, and is currently in many places clearly too high. In the long term, this is likely to cause losses in forest ecosystem services, in particular so since it must be feared that ungulate impacts will further increase. The problem is accentuated by climate change which creates the need for a higher share of tree species that tolerate a warmer and drier climate, but are sensitive to browsing. Solutions to secure forest services are urgently needed, especially in mountain forests where protective measures to prevent damage are largely impractical. To find such solutions, an intensified communication between the players is most important. Moreover, the following approaches seem promising: 1) coherence in the objectives, 2) improved foundations for decision-making, 3) measures to bring ungulate populations in line with the available habitat und 4) the study and documentation of success stories.
Variable Selection Using Adaptive Band Clustering and Physarum Network
Authors: Chen Huanyu , Chen Tong , Zhang Zhihao , Liu Guangyuan
Published: June 2017

Variable selection is a key step for eliminating redundant information in spectroscopy. Among various variable selection methods, the physarum network (PN) is a newly-introduced and efficient one. However, the whole spectrum has to be equally divided into sub-spectral bands in PN. These division criteria limit the selecting ability and prediction performance. In this paper, we transform the spectrum division problem into a clustering problem and solve the problem by using an affinity propagation (AP) algorithm, an adaptive clustering method, to find the optimized number of sub-spectral bands and the number of wavelengths in each sub-spectral band. Experimental results show that combining AP and PN together can achieve similar prediction accuracy with much less wavelength than what PN alone can achieve.
Antibacterial Activity and Toxicity of Analogs of Scorpion Venom IsCT Peptides

Published: June 2017

Seven analogs of the natural, α-helix peptides IsCT1 and IsCT2—found in the venom of scorpion Opithancatus Madagascariensis—have been synthesized and tested to compare their antibacterial and hemolytic activity against natural peptides. In general, results show that increasing hydrophobicity by substituting positions 5 and 9 of the sequences with alanine, valine, and leucine, enhances antibacterial activity. However, this also increases hemolytic activity. The analog with an increased net positive charge from +1 to +3 produces moderate bacterial growth inhibition but also has high hemolytic activity. On the other hand, the analog with a negative net charge (−1) has low antibacterial properties but also no cytotoxicity under the tested conditions, a similar result was found for five of the seven studied analogs.
A Single Gyroscope Can Be Used to Accurately Determine Peak Eversion Velocity during Locomotion at Different Speeds and in Various Shoes

Published: June 2017

Gyroscopes have been used in previous studies to measure the peak angular velocity of the shoe or foot in the frontal plane (evVel). However, it is not clear whether different test conditions (footwear hardness or locomotion speed) can influence the accuracy of evVel. The purpose of the present study was to compare the accuracy of gyroscopes and electrogoniometers when measuring evVel and the time until evVel (t_evVel) in 12 different conditions using a single axis gyroscope attached to the heel cap. Twenty-four recreational runners were instructed to walk and run on a 15-m indoor track at four locomotion speeds (1.5, 2.5, and 3.5 m/s, and individual running speed) and in three footwear conditions (low to high hardness). The gyroscope data and electrogoniometer data were sampled at a rate of 1000 Hz. Comparisons between both measurement devices showed small mean differences up to 49.8 ± 46.9 deg/s for evVel and up to 5.3 ± 3.5 ms for t_evVel. Furthermore, strong relationships between gyroscope and electrogoniometer data were found for evVel as well as for t_evVel for all conditions. It can be concluded that gyroscopes can be used to accurately determine evVel and t_evVel under a variety of conditions.
Analysis of Land Cover Classification Using Multi-Wavelength LiDAR System
Authors: Teo Tee-Ann , Wu Hsien-Ming
Published: June 2017

The airborne multi-wavelength light detection and ranging (LiDAR) system measures different wavelengths simultaneously and usually includes two or more active channels in infrared and green to acquire both topographic and hydrographic information. The reflected multi-wavelength energy can also be used to identify different land covers based on physical properties of materials. This study explored the benefits of multi-wavelength LiDAR in object-based land cover classification, focusing on three major issues: (1) the evaluation of single- and multi-wavelength LiDARs for land cover classification; (2) the performance of spectral and geometrical features extracted from multi-wavelength LiDAR; and (3) the comparison of the vegetation index derived from active multi-wavelength LiDAR and passive multispectral images. The three-wavelength test data were acquired by Optech Titan in green, near-infrared, and mid-infrared channels, and the reference data were acquired from Worldview-3 image. The experimental results show that the multi-wavelength LiDAR provided higher accuracy than single-wavelength LiDAR in land cover classification, with an overall accuracy improvement rate about 4–14 percentage points. The spectral features performed better compared to geometrical features for grass, road, and bare soil classes, and the overall accuracy improvement is about 29 percentage points. The results also demonstrated the vegetation indices from Worldview-3 and Optech Titan have similar characteristics, with correlations reaching 0.68 to 0.89. Overall, the multi-wavelength LiDAR system improves the accuracy of land cover classification because this system provides more spectral information than traditional single-wavelength LiDAR.
