Aaron Goodfellow, 'Pharmaceutical Intimacy: Sex, Death, and Methaphetamine'
Sophie Bennet
Opticon1826 , 2009, DOI: 10.5334/opt.070911
Abstract: In 2008, Aaron Goodfellow challenged boundaries in sociology, anthropology and material culture studies with his article on sex, death and methamphetamine – an article which refuses to view drug (ab)use from a moral perspective. The result is a fascinating analysis of Mathew’s life. Mathew is a 24-year-old, white, HIV-positive crystal methamphetamine user, in a Baltimore rehabilitation institute on state parole, and receiving antiretroviral therapy (ART). In Mathew’s own words, he is ‘a public health threat number one, huh? (I’m) a gay crystal using, HIV positive convict’ (quoted in Goodfellow 2008, 280). Through his interactions with Mathew, Goodfellow explores the anthropological issue of the contingency of specific substances and of personhood within a modern, urban context, on the edge of ‘normative society’. The article supports the validity of Tilley’s work on objectification (2006); people and things (in this case, substances) are indivisible. The author encourages us to view Mathew’s situation not as an addiction, but as a partnership between Mathew and substances: Mathew often responds creatively to the substance’s agency with his own agency. In this review, I will briefly discuss the thought-provoking aspects of Goodfellow’s account, which will hopefully encourage you to read the article in full.
A derivation of the Catalan numbers from a bijection between permutations and labeled trees
Bennet Vance
Mathematics , 2001,
Abstract: We present an algorithmic mapping from permutations of length dn to labeled n-node d-ary trees and back again. Given such a bijection, one can interpret each of the factorials in the formula for the Catalan numbers as a count of permutations.
Profound Hypothermia Secondary to Clobazam Use in Epilepsy: A Novel Association  [PDF]
Marc P. DiFazio, Bennet Lavenstein, Scott Demarest
Neuroscience & Medicine (NM) , 2014, DOI: 10.4236/nm.2014.51003
Abstract:

Clobazam, a 1-5 benzodiazepine, was introduced in the 1970s for the treatment of anxiety and agitation. Antiepileptic properties were recognized, and efficacy in a number of epilepsy syndromes was demonstrated in humans, with good tolerance. Recent reviews are generally favorable, with a relative minimum of medication-related side effects. However, a number of benzodiazepines have been associated with causing hypothermia. To date, this side effect has not been reported with clobazam. We report two cases of profound hypothermia associated with the use of this medication for the treatment of epilepsy. Both children had significant cerebral dysgenesis and were developmentally impaired, but neither had experienced hypothermia before. Temperature dysregulation was resolved with medication withdrawal after an extensive work-up for alternative causes. Hypothermia should be considered as a possible side effect of clobazam, although the exact mechanism is unknown. Appropriate monitoring of temperature is appropriate, and precautions should be offered by caregivers.

Distribution and seasonality of vertically transmitted dengue viruses in Aedes mosquitoes in arid and semi-arid areas of Rajasthan, India
Bennet Angel,Vinod Joshi
Journal of Vector Borne Diseases , 2008,
Abstract: Background & objectives: Transovarial transmission of dengue virus is a crucial etiological phenomenon responsible for persistence of virus during inter-epidemic period of the disease. Distribution and seasonality of this phenomenon in disease endemic areas may contribute to explain emergence of dengue and its subsequent prevention. The study on seasonal and area distribution of transovarial transmission of dengue virus in Aedes aegypti, Ae. albopictus and Ae. vittatus has been made in desert and non-desert districts of Rajasthan, India from 2006 to 2007. The observations revealed role of different Aedes species in transmission and retention of dengue virus.Methods: The larvae of Ae. aegypti, Ae. albopictus and Ae. vittatus were collected during each of the study seasons from rural and urban areas of three districts—Jodhpur, Jaipur and Kota. The larvae were collected from domestic and peri-domestic containers and from tree holes of peri-urban foci such as gardens and parks and were reared into adults in the laboratory at room temperature. The laboratory reared adults were subjected to Indirect fluorescence antibody test (IFAT). The laboratory-reared adult mosquitoes showing positive IFA were treated as the sample showing vertically transmitted dengue virus.Results: Pooled data for all the four seasons revealed maximum (15.7%) mosquito infectivity in Ae. albopictus followed by Ae. aegypti (12.6%) in Jodhpur district. In Jaipur district, Ae. vittatus showed highest infection (20%) of vertically transmitted virus followed by Ae. albopictus (18.7%) and least in Ae. aegypti (13.3%). In Kota district, pooled data for all the four seasons showed maximum vertical infection of mosquitoes in Ae. albopictus (14.2%).Interpretation & conclusion: Transovarial transmission of dengue virus by available vector species in a dengue endemic setting could be the key etiological phenomenon responsible for re-emergence of the disease from inter-epidemic to epidemic phase of disease onset. The observations in the present study suggest that during winter season which is not the active transmission season of dengue in Rajasthan, Ae. albopictus has shown maximum percentage of vertically transmitted virus. Our observation substantiates with the earlier studies that how Ae. albopictus is horbouring virus during inter-epidemic period of dengue. Another important lead emerging through present study is the high mosquito infectivity of Ae. aegypti during summer and rainy seasons especially from desert districts, Jodhpur and semi district. This observation suggests that in Rajasthan, ow
‘He wasn’t in that chair’: what loneliness means to widowed older people
Kate Mary Bennet,Christina Victor
International Journal of Ageing and Later Life , 2012,
Abstract: We have little robust empirical evidence that articulates what being lonely means to older people and even less knowledge about what loneliness means to older widows and widowers; this article addresses that deficit. We undertook a re-analysis of 125 interviews with older people (aged 55-98) that explored their experiences of widowhood. In this article, we focus on those interviews in which participants described themselves as experiencing loneliness by the spontaneous use of terms such as ‘‘lonely’’, ‘‘loneliness’’ or ‘‘lonesome’’. Almost half of the participants (42%) described themselves in that way without any prompting from the interviewer. In terms of understanding and describing the meaning of loneliness, 50% explained loneliness in terms of absence of either their spouse, a physical presence in the house or people. One-third (34%) discussed loneliness in relation to time and place: night, weekends and home, and 4% described the emotional impact of loneliness. Fifteen per cent just said they were lonely without elaboration, assuming a common understanding of what loneliness means. Our findings suggest that widowed people’s understanding and experience of loneliness resonates with the concept of ‘‘emotional’’ loneliness, resulting from the loss of significant social and emotional attachment. This has important implications for the types of interventions that may be appropriate for remediating loneliness in this group.
Fingerprint Matching Using Hierarchical Level Features
D. Bennet,S. Arumuga Perumal
International Journal of Computer Science Issues , 2011,
Abstract: This paper proposes a fingerprint features extraction using different levels. The hierarchical order at four different levels, namely, Level 1 (pattern), Level 2 (minutia points), Level 3 (pores and ridge contours), and Level 4 (oscillated pattern). The fingerprint feature extraction frequently take advantage of Level 4 features to assist in identification, Automated Fingerprint Identification Systems (AFIS) currently rely only on Level 1 and Level 2 features. In fact, the Federal Bureau of Investigation's (FBI) standard of fingerprint resolution for AFIS is 500 pixels per inch (ppi), which is inadequate for capturing Level 3 features, such as pores. With the advances in fingerprint sensing technology, many sensors are now equipped with dual resolution (1,000 ppi) scanning capability. However, increasing the scan resolution alone does not necessarily provide any performance improvement in fingerprint matching, unless an extended feature set is utilized. As a result, a systematic analysis to determine how much performance gain one can achieve by introducing Level 4 features in AFIS is highly desired. We propose a hierarchical matching system that utilizes features at all the four levels extracted from 1,000-ppi fingerprints scans. Level 3 features, pores and ridge contours are automatically extracted using Gabor filters and wavelet transform and are locally matched using the Iterative Closest Point (ICP) algorithm and Level 4 features, oscillated pattern including curve scanned DCT to measure the recognition rate using k-nn classifier, Our analytical study conclude Level 4 features carry significant discriminatory information. The matching system when Level 4 features are employed in combination with Level 1 Level 2 and Level 3 features. This proposed method outperforms the others, particularly in recognition rate.

International Journal of Nanomedicine , 2012, DOI: http://dx.doi.org/10.2147/IJN.S32800
Abstract: al drug-loaded nanoparticles on self-integrated scaffold for controlled delivery Original Research (2862) Total Article Views Authors: Bennet D, Marimuthu M, Kim S, An J Published Date July 2012 Volume 2012:7 Pages 3399 - 3419 DOI: http://dx.doi.org/10.2147/IJN.S32800 Received: 10 April 2012 Accepted: 14 May 2012 Published: 16 July 2012 Devasier Bennet,1 Mohana Marimuthu,1 Sanghyo Kim,1 Jeongho An2 1Department of Bionanotechnology, Gachon University, Gyeonggi, Republic of Korea; 2Department of Polymer Science and Engineering, SunKyunKwan University, Gyeonggi, Republic of Korea Abstract: Antioxidant (quercetin) and hypoglycemic (voglibose) drug-loaded poly-D,L-lactide-co-glycolide nanoparticles were successfully synthesized using the solvent evaporation method. The dual drug-loaded nanoparticles were incorporated into a scaffold film using a solvent casting method, creating a controlled transdermal drug-delivery system. Key features of the film formulation were achieved utilizing several ratios of excipients, including polyvinyl alcohol, polyethylene glycol, hyaluronic acid, xylitol, and alginate. The scaffold film showed superior encapsulation capability and swelling properties, with various potential applications, eg, the treatment of diabetes-associated complications. Structural and light scattering characterization confirmed a spherical shape and a mean particle size distribution of 41.3 nm for nanoparticles in the scaffold film. Spectroscopy revealed a stable polymer structure before and after encapsulation. The thermoresponsive swelling properties of the film were evaluated according to temperature and pH. Scaffold films incorporating dual drug-loaded nanoparticles showed remarkably high thermoresponsivity, cell compatibility, and ex vivo drug-release behavior. In addition, the hybrid film formulation showed enhanced cell adhesion and proliferation. These dual drug-loaded nanoparticles incorporated into a scaffold film may be promising for development into a transdermal drug-delivery system.
Determinants of Workers Health and Safety in the Malaysian Wooden Furniture Industry
J. Ratnasingam,F. Ioras,M. Bennet
Journal of Applied Sciences , 2010,
Abstract: Despite its socioeconomic importance and the labour intensive nature of the sector, the status of the health and safety of the workers in the Malaysian wooden furniture industry has not been studied and reports on the subject is sparse. Therefore, the safety climate, which defines the safety level of the work environment, in the Malaysian wooden furniture industry was studied in thirty wood-furniture manufacturing factories, using a structured questionnaire. The study found that although there were four determinants of the prevailing safety climate in the work environment, it was the management responsibility and safety precautions that had the strongest influence on safety climate. Further, the primary health and safety concerns in the wooden furniture manufacturing industry were the air-borne dust, noise, chemical exposure, materials handling and occupational accidents. In this context, it is essential for the management to show commitment towards health and safety and incorporate safety precautions into the operational system, to ensure a safe working environment in the wooden furniture manufacturing industry.
Early versus Late Tracheostomy for Ventilator Dependence after Cardiovascular Surgery: Long-Term Results  [PDF]
Joseph M. Ladowski, Hannah E. Downey, Bennet J. Ladowski, Joseph S. Ladowski
World Journal of Cardiovascular Surgery (WJCS) , 2013, DOI: 10.4236/wjcs.2013.33022
Abstract:

Although concerns exist about the possibility of infecting a sternotomy wound by performing a tracheostomy early after cardiac surgery, it has been shown that tracheostomy performed before postoperative day 10 can improve outcomes for cardiovascular surgery patients who require long-term ventilation. We retrospectively reviewed all charts for patients who underwent cardiovascular surgery and required tracheostomy at a single-institution site from January 2005 to July 2012. Patients were divided into two groups based upon whether their tracheostomy was performed less than 10 days after their initial operation (early tracheostomy) or ≥10 days after their initial operation (late tracheostomy). Preoperative demographics and postoperative complications were studied. There were no new mediastinitis episodes following tracheostomy. Early tracheostomy was associated with higher 90-day (74.4% vs 56.8%) and 180-day (47.4% vs 28.7%, p < 0.047) survival when compared to late tracheostomy. Early tracheostomy after cardiovascular surgery does not seem to be associated with an increased rate of mediastinitis but is associated with improved survival.

Nonlinear light localization around the core of a `holey' fiber
Francis H. Bennet,Mario I. Molina
Physics , 2011, DOI: 10.1364/JOSAB.29.002161
Abstract: We examine localized surface modes in the core of a photonic crystal fiber composed of a finite nonlinear (Kerr) hexagonal waveguide array with a central defect. Using a discrete approach, we find the fundamental surface mode and its stability window. We also examine an unstaggered, ring-shaped surface mode and find that it is always unstable, decaying to the single-site fundamental surface mode. A continuous model computation reveals that an initial vortex excitation (S=1) of small amplitude around the central hole can survive for a relatively long evolution distance. At high amplitudes, however, it decays to a ring configuration with no well-defined phase structure.
