Chemistry in Calixarenes and Radicals: Inclusion, Spin Label, Reaction, and ESR Studies
Authors: Li Yong , Yang Haijun 
Published: June 2010

Abstract
Due to inclusion function and easy chemical modification of calixarenes, they should be able to form inclusion complexes with free radicals, spin labeled calixarenes, and polyradicals based on calixarene skeletons. It is therefore important not only to utilize radicals as spin probes to investigate inclusion function and conformational changes of calixarenes, but also to develop potentially new molecular magnetic devices and materials. Recent research advances, especially using ESR technique, in interdiscipline of calixarene and radical, are briefly reviewed.

Published: June 2010

Abstract
A new process for comprehensively utilizing ilmenite is studied. FePO4·xH2O, and Ti-containing precursors are prepared from the iron-rich lixivium and titanium hydrolysate, which are obtained from ilmenite by mechanical activation and leaching. ICP analysis confirms that the FePO4·xH2O contains small amounts of Al and Ti (Fe:Al:Ti = 100:1.69:1.09) and that the Ti-containing precursor contains a small amount of Si (Ti:Si = 100:0.86). LiFePO4 and Li4Ti5O12 synthesized from the as-prepared precursors exhibit well-crystallized structure, nanoscale particles, and excellent electrochemical properties.

Near-infrared Reflecting Yellow Inorganic Pigments Based on Molybdenum-doped Yttrium Cerate: Synthesis, Characterization, and Optical Properties
Authors: Vishnu Viswanadhan Sarasamma , Reddy Mundlapudi Lakshmipathi 
Published: June 2010

Abstract
A new series of yellow inorganic pigments possessing high near-infrared (NIR) reflectance (91–96% at 1100 nm), based on molybdenum-doped yttrium cerate was synthesized by traditional solid-state route. The band gap of the designed pigments changes from 3.01 to 2.44 eV, displaying colors ranging from ivory-white to yellow. The coloring mechanism is attributed to the O2p–Mo4d charge-transfer transition. The pigments are environmentally benign and effectively confer their NIR reflectance properties to a roofing material like asbestos.
Ion-exchange-induced Phase Separation and Preparation of Porous Glass
Authors: Kadono Kohei , Hattori Yuki , Wakasugi Takashi , Shiomi Haruhisa , Nishii Junji 
Published: June 2010

Abstract
Utilizing the difference in the size of the immiscibility regions with alkali ions, phase separation was induced at the surface of 70SiO2·15B2O3·15Na2O (mol %) glass by ion exchange in which Na+ ions were replaced by Li+ ions in molten LiNO3 salt at 400 °C. The heat treatment after the ion exchange made the phase separation proceed and formed phases which can be dissolved by acid treatment. Through the ion-exchange-induced phase separation, we prepared monolithic glasses, in which only the surface region is porous and the rest is homogeneous and transparent.

Authors: Tsutsumi Ken , Terao Kimitada , Yamaguchi Hiroki , Yoshimura Syogo , Morimoto Tsumoru , Kakiuchi Kiyomi , Fukuyama Takahide , Ryu Ilhyong 
Published: June 2010

Abstract
Diastereoselective [2 + 2] photocycloaddition of chiral cyclohexenone 1 with cyclopentene was conducted using a continuous microflow reactor. This reaction led to photoadducts 2 and 3 in a shorter reaction time and with a higher diastereoselectiviy than the corresponding reaction in a batch reactor. The effect of temperatures on the selectivities of both reaction systems is also discussed.
Idolatry versus authenticity: A lexical and systemic-functional analysis of the coverage of the World Youth Day 2005 in the Flemish press
Authors: Temmerman Martina , Trioen Marit 
Published: June 2010

This article investigates the way (catholic) religion and youth are represented in different Flemish newspapers. The case of World Youth Day (WYD) 2005 offers a well-defined corpus, which is very suitable for an analysis of the discourse on religion, youth and media.
Based on a linguistic
analysis of the corpus, we have been able to describe the representation given to the WYD, of the presence of the pope and of the young participants. It turns out that, although the coverage is on the whole very precise, it shows remarkable patterns of inconsistency.
On the one hand, most
newspapers overemphasize the meaning of the presence of the pope at the WYD in relation to the overall meaning of the event. But this idolatry does not correspond with the view of the Flemish participants, who also get a lot of attention and who are represented in an authentic way. Furthermore,
in a number of cases, the journalists revert to presuppositions and stereotypes in their representation of the event.
Thinking loudly about media approaches to Islam: Understanding the Qur'anic text, or spinning a mass-mediated meaning?
Authors: Saleh Ibrahim 
Published: June 2010

Religion and the media are today intertwined in powerful and profound ways. This reflects a situation of much significance. The dilemma is that (for many) the media is the central source of information about religions other than our own, and yet it seems ill prepared for the role it
plays. Besides, religion can no longer control its own story or its own symbols, or how these religious ideas, symbols and claims surface.
The text of the Qur'an has been a point of endless controversial debates. Many of the argumentative issues such as suicide killings, polygamy and female
genital mutilation have been a result of people misreading the Qur'an text, and not putting the meaning in context. These misconceptions have all resulted in the global misperception of the holy text of Muslims.
Audiences and societies face a double jeopardy because of the current trend
for global crusading journalism and campaigning journalist(s). The real motivations behind the current media approaches to Islam is the real controversy here, and the question remains on whether such misinterpretation of the Qur'an is religious as it appears, or is it in fact
a politically manipulated enigma?
Quartz crystal microbalance-based biosensor for the detection of α-thalassemia 1 (SEA deletion)
Authors: Chomean Sirinart , Potipitak Tiparat , Promptmas Chamras , Ittarat Wanida 
Published: June 2010

Abstract

Background: DNA piezoelectric biosensors have become a promising tool in molecular medicine since they do not require any label or staining. Here, a DNA piezoelectric biosensor based on a quartz crystal microbalance (QCM) was created to identify abnormal genes causing α-thalassemia 1 (SEA deletion).

Methods: The functionalized gold electrode of the quartz crystal was coated with avidin and the biotinylated DNA probe was attached. The target gene causing α-thalassemia 1 was amplified and hybridized with the immobilized probe. DNA hybridization was indicated by changes in the quartz resonance frequencies. Diagnostic ability of the new α-thalassemia 1 biosensor was validated using both known and unknown blood samples. Specificity was tested using samples of β-thalassemia and α-thalassemia 2. Stability of the sensor was also evaluated.

Results: The new biosensor could clearly identify α-thalassemia 1 (SEA deletion), both carrier and disease states, from the normal genotype. Identification accuracy was compatible to the standard gel electrophoresis. It was specific only to α-thalassemia 1 since no cross reaction was found with β-thalassemia and α-thalassemia 2. The sensor could be kept at room temperature up to 6 months with consistent identification accuracy.

Conclusions: The label free QCM based biosensor was successfully developed to diagnose an abnormal human globin gene causing α-thalassemia 1 (SEA deletion). Its accuracy, specificity and sensitivity were comparable to the standard method. Its stable diagnostic potency up to 6 months implied its field application in thalassemic control program.

Authors: Nesse Willem , Dijkstra Pieter U. , Abbas Frank , Spijkervet Fred K.L. , Stijger Astrid , Tromp Jan A.H. , van Dijk Johan L. , Vissink Arjan 
Published: June 2010

Background: Associations between periodontitis and cardiovascular and autoimmune diseases are most often assessed in patients with a particular cardiovascular or autoimmune disease. To prevent selection bias, this study assesses the existence of associations between periodontitis and cardiovascular and autoimmune diseases in patients attending a dental or periodontal clinic.Methods: Data were collected from 1,276 randomly selected dental records from patients attending a dental (n = 588) or periodontal (n = 688) clinic. Data on the prevalence of cardiovascular and autoimmune diseases were obtained from a validated health questionnaire. Data on the presence of periodontitis were taken from patients’ dental records.Results: In uncontrolled analyses, the prevalence of hypertension, diabetes mellitus (DM), and rheumatoid arthritis (RA) is significantly increased in patients with periodontitis. Controlled for confounding, periodontitis was associated with DM, with an odds ratio of 4 (1.03 to 15.3), in the dental clinic. DM was not associated with periodontitis in periodontal clinics. Hypertension does not seem to be associated with periodontitis when controlling for confounders. Periodontitis may be associated with RA in both clinic types.Conclusions: The increased prevalence of cardiovascular and autoimmune diseases among patients with periodontitis attending dental or periodontal clinics may, at least in part, be influenced by confounding. However, the increased prevalence of DM and RA in patients with periodontitis could not be explained by confounding.
ZNF300, a recently identified human transcription factor, activates the human IL-2Rβ promoter through the overlapping ZNF300/EGR1 binding site
Authors: Xue Lu , Qiu Hongling , Ma Jian , Guo Mingxiong , Li Wenxin 
Published: June 2010

AbstractZNF300 was recently identified as a member of the human KRAB/C2H2 zinc finger protein family. Little is known about the role of ZNF300 in human gene regulation networks. In this study, the DNA-binding property of ZNF300 was further analyzed. We found that the recombinant ZNF300 could bind to the binding site 5′-GCGGGGGCG-3′ of Egr1, another member of the KRAB/C2H2 zinc finger protein family. Similarly, recombinant Egr1 also showed a similar binding affinity to the ZNF300 binding site 5′-CTGGGGGCG-3′. Bioinformatics analysis revealed that there is an overlapping ZNF300/Egr1 binding site in the human IL-2Rβ promoter region, which was previously known to be recognized by endogenous Egr1. Electrophoretic mobility shift assays showed that endogenous ZNF300 could also bind to this site. A transient transfection assay revealed that both ZNF300 and Egr1 could transactivate the IL-2Rβ promoter, and that the activation was abrogated by a mutation of residues in the overlapping ZNF300/Egr1 binding site. Co-expression of ZNF300 and Egr1 led to enhanced IL-2Rβ promoter activity. Thus, ZNF300 is likely to be another regulator of the human IL-2Rβ promoter.
CPU COOLING OF DESKTOP COMPUTER BY PARALLEL MINIATURE HEAT PIPES
Authors: Feroz Chowdhury Md. , Uddin Ahmed Imtiaz 
Published: June 2010

Heat transfer performance of parallel miniature heat pipes (MHPs) of 2.8 mm ID used for cooling desktop computer with different working fluids is presented in this paper. In cooling desktop processors, MHPs consists of six single tube heat pipes connected by a copper block at the evaporator section and fifteen parallel copper sheets used as external fins at the condenser section. Acetone and ethanol are used as working fluid. The copper block is placed above the heat source (on the top of the processor) and the condenser section is provided with external fins perpendicular to the MHPs. Heat transfer characteristics of MHPs using different working fluids are determined experimentally, based on the principle of phase. The experimental results show that, the maximum and steady state temperature of the processor has been reduced significantly by using MHPs with acetone as working fluid instead of conventional cooling fan. Additional use of a fan at the condenser section results much lower processor surface temperature for both working fluids. Key words: CPU cooling; Desktop processor; Heat transfer performance; Miniature Heat Pipe; Working fluid.DOI: 10.3329/jme.v40i2.5351Journal of Mechanical Engineering, Vol. ME 40, No. 2, December 2009 104-109
NEW APPROACH OF CLASSIFICATION OF ROLLING ELEMENT BEARING FAULT USING ARTIFICIAL NEURAL NETWORK
Authors: Hariharan V. , Srinivasan PSS. 
Published: June 2010

The paper presents a new approach to the classification of rolling element bearing faults by implementing Artificial Neural Network. Diagnostics of rolling element bearing faults actually represents the problem of pattern classification and recognition, where the key step is feature extraction from the vibration signal. Characterization of each recorded vibration signal is performed by a combination of signal's time-varying statistical parameters and characteristic rolling element bearing fault frequency components obtained through the frequency spectrum analysis method. The experimental data is collected for four bearings at three different speeds. The sensor is located at three different positions for each bearing. Both time domain and frequency domain signals were measured. Thus the data was three time spectrums and three frequency spectrums for each speed for a bearing. The entire data set comprised of 72 (6 x 3 x 4) data. The time domain signal was comprised of 8192 samples and extracting these features from a huge data set was difficult. To overcome this difficulty the 8192 samples were split into 32 bins each containing 256 samples. Two Network RBFN and PNN are used to classify the bearing defects. The entire process of splitting and evaluating the seven features was coded in MATLAB. From these seven features the most suitable features are for explaining the intensity of the defect is discussed.Key Words: Feature Extraction; Fault Frequencies; Roller Bearing; Bearing fault; Crest Factor; Variant;Radial Basis Function Network (RBFN); Probabilistic Neural Network (PNN)DOI: 10.3329/jme.v40i2.5353Journal of Mechanical Engineering, Vol. ME 40, No. 2, December 2009 119-130

Authors: Castiglioni P. , Rizzo F. , Faini A. , Mazzoleni P. , Lombardi C. , Meriggi P. , Parati G. , Di Rienzo M. ,   the HIGHCARE investigators
Published: June 2010

Summary
Objectives: To investigate the effects of hypoxia during sleep on linear and self-similar components of heart rate variability (HRV) in eight healthy subjects at high altitude on Mount Everest.
Methods: ECG was monitored by using an innovative textile-based device, the MagIC system. For each subject three night recordings were performed at sea level (SL), at 3500 m and 5400 m above SL. RR Interval (RRI) was derived on a beat-by-beat basis from the ECG and the VLF, LF and HF spectral components and the LF/HF ratio were estimated. Short-(α1) and long-term (α2) scale exponents as well as the recently proposed spectrum of self-similarity coefficients, α(n) were estimated by detrended fluctuation analysis (DFA).
Results: With respect to SL, all HRV parameters but one (α2) were significantly modified at 3500 m. However, at 5400 m they tended to return to the SL values and this was in contrast with the increase in the hypobaric hypoxia and in the number of central sleep apneas occurring at higher altitude. The only HRV index that displayed changes at 5400 m was the DFA α(n) spectrum, with α(n) values significantly lower than at SL for 20 < n < 50 and higher for 200 < n < 400, being n the box size..
Conclusions: While the biological interpretation of these results is still in progress, our data indicates that the cardiac response to high altitude hypoxia during sleep can hardly be fully explored by traditional HRV estimators only, and requires the additional support of more sophisticated indexes exploring also nonlinear and fractal features of cardiac variability.

Effects of intra-articular botulinum toxin type A (Botox®) in dogs with chronic osteoarthritis
Authors: Wheeler J. L. , Petersen S. W. , Hadley H. S. 
Published: June 2010

Summary
Objectives: To evaluate the effects of intra-articular botulinum neurotoxin type A (BoNT/A) in dogs with chronic osteo-arthritis.
Methods: Client-owned dogs with lameness and discomfort attributed to unilateral elbow or hip osteoarthritis were eligible for inclusion (n = 5). All dogs had BoNT/A (25 units) administered to the affected joint (2 elbows, 3 hips). Dogs were evaluated by pressure platform gait analysis before and at two, four, eight, and 12 weeks post-injection, and by client perception of outcome.
Results: In experimental limbs, ground reaction forces (peak vertical force and vertical impulse) consistently improved for a variable period of time following intra-articular BoNT/A therapy. These changes were not, however, observed in the contralateral limbs, in which values remained relatively unchanged or decreased. Four out of five owners reported at least some improvement in their dog’s condition following treatment.
Clinical significance: A multimodal approach with the intra-articular administration of BoNT/A may be an option for osteoarthritis patients that are unresponsive to medical management and unable to undergo surgery. However, the findings of this study are preliminary and must be verified by further investigation.

Published: June 2010

SummaryAn eight-month-old, 31.2 kg, entire male Golden Retriever was presented for evaluation because it had a four-week history of right hindlimb lameness and audible popping occurring in association with movement of the right hindlimb. Mild right hindlimb lameness was noted upon gait analysis. Moderate to severe effusion and pain on extension were appreciated on palpation of the right tarsus. Dorsoplantar and lateral radiographs of the right tarsus revealed significant soft tissue swelling over the lateral aspect of the tarsus and widening of the joint space over the lateral trochlear ridge of the talus. A fracture of the lateral ridge was appreciated upon evaluation of the flexed dorsoplantar view. Un-enhanced computed tomography of the right tarsus confirmed fracture of the talus one large and two small bone fragments were noted adjacent to the lateral aspect of the lateral trochlear ridge and medial to the fibula. The fracture was surgically repaired via a lateral approach a fibular osteotomy was performed. The fragment was manually reduced and secured with a 1.5 mm cortical screw placed in lag fashion. The fibular osteotomy site was reduced and fixed with two 1.6 mm Kirshner wires and a tension band composed of 0.9 mm cerclage wire. The patient made a complete clinical recovery, however, the union was fibrous and evidence of mild osteo-arthritis was noted on postoperative radio-graphs.
