Determination of Integrated Molar Absorption Coefficients for Gaseous Phenol Infrared Bands and Influence of Water Vapor on Their Values  [PDF]
Thomas Onfroy, Olivier Marie
American Journal of Analytical Chemistry (AJAC) , 2019, DOI: 10.4236/ajac.2019.101002
Abstract: The integrated molar absorption coefficients for ν(OH) (3655 cm-1), δ(OH) (Q branch at 1176 cm-1 or whole bands), [ν(CCring) + δ(OH)] (Q branch at 1344 cm-1 or whole bands) and γ(CH) (752 cm-1) were determined at 342 K, by recording infrared spectra of pure gaseous phenol at different partial pressure (from 0 to 33 Pa). The integrated molar absorption coefficients (ε) values were obtained with a good reproducibility and the relative uncertainty on the given values is below 2%. The influence of water on the integrated molar absorption coefficients of phenol has been investigated in a large range of nwater/nphenol values (from 0.5 to 6.1 and from 44 to 94) using distinct setups. The infrared spectra of a gas mixture containing a constant amount of phenol and different amount of water were recorded (closed cell) whereas in dynamic condition (under flow) the water partial pressure was kept constant at 1.3 kPa and the phenol partial pressure was increased from 0 to 30 Pa. It is here demonstrated that, at 342 or 355 K, the presence of water does not affect the epsilon values of δ(OH) and [ν(CCring) + δ(OH)] bands.
Mitochondrial Dysfunction in Duchenne Muscular Dystrophy  [PDF]
Marie Kelly-Worden, Emily Thomas
Open Journal of Endocrine and Metabolic Diseases (OJEMD) , 2014, DOI: 10.4236/ojemd.2014.48020
Abstract:

Muscular Dystrophy (MD) is an X-linked recessive disease affecting mainly boys at a rate of 1 in every 3500 live births. The most common and severe form of the disease is Duchenne Muscular Dystrophy (DMD). The disease is characterized by a relatively rapid wasting of skeletal muscle tissue to a point that leads to paralysis in all patients that suffer from the disease. Unfortunately, due to respiratory or cardiac muscle failure, death occurs in most patients around the age of 30. Currently, the lack of the protein dystrophin is thought to be the chief cause of disease in DMD patients. In addition to a lack of dystrophin, studies are emerging that are painting a picture of a more intricate connection between mitochondrial dysfunction and DMD where increased intracellular and inter-mitochondrial calcium has been shown to cause mitochondrial swelling, loss of mitochondrial membrane integrity, cell death and muscle atrophy. In this article, we will discuss the evidence that places the mitochondrion as a central participant in the etiology of DMD and describe how the relationship between increased intracellular calcium, mitochondrial permeability and dysfunction culminates in muscle loss.

Adaptation of Resilience against Disaster— Case Study of 2000 Tokai Flood and 2011 Flood in Shonai River, Japan  [PDF]
Marie Thomas, Makiko Obana, Tetsuro Tsujimoto
Natural Science (NS) , 2015, DOI: 10.4236/ns.2015.71004
Abstract: In this study, the application of the resilience concept of the flood event depending on progress of the time is analyzed as the hazard occurrence, the disaster risk, the damage risk, and the evolution of the damages. Flood disaster is defined as the occurrence of an inundation in an exposed area. The human exposure (loss of life, injury, ), structural (buildings, roads, ) and functional (economic, political, functions of an area) economic exposure cause high risk of damage if the area in which the hazard occurs is at low resilience. Furthermore the damage will increase without adequate response against disaster. The flood disaster risk is decreased by flood control measures, reducing structural and functional exposure. Non-structural measures, such as appropriate prior-evacuation, decrease the human exposure to flood disaster. This study reviews the events of 2000 and 2011 floods in the Shonai River basin in Japan to help assess resilience to flood disaster. These two events had the same type of hazards in intensity and location, allowing the study in terms of adaptation to flood disaster in the river basin to focus on the structural and nonstructural effort to increase resilience of the disaster depending on progress of the time.
Le cadre bati : les formes face à la norme.
Marie-Paule Thomas
EspacesTemps.net , 2009,
Abstract: Quelle est la portée réelle de la règle et des conventions dans l’aménagement urbain ? Comment les acteurs sociaux tentent-ils de l’instrumentaliser ou de s’en échapper ? En contraste d’une perspective strictement normalisatrice, considérons que la forme urbaine se modèle au gré des projets, au gré des rentabilités, au gré même de la concurrence entre les formes parfois symboliques de la ville.

Complex trauma and borderline personality disorder  [PDF]
Joanic Masson, Amal Bernoussi, Marie Cozette Mience, Fran?ois Thomas
Open Journal of Psychiatry (OJPsych) , 2013, DOI: 10.4236/ojpsych.2013.34044
Abstract:

The aim of this article is to bring together the concepts of borderline pathology and complex trauma. We wish to show that the symptomatology characteristic of borderline pathology approaches, is indeed similar to, that of Non-Specific Extreme Stress (NSES) states. Thus the hypothesis is that states of NSES and borderline pathology constitute psychopathological entities which overlap but reflect different paradigms. The former is linked to the field of psychotraumatology while the latter is more rooted in psychoanalytic theory. In this way traumatic etiology opens the way for the clinician to explore new psychotherapeutic strategies.

Evaluation of Health and Environmental Risks of Pesticide Products Used in Market-Gardening in the City of Ngaoundere (Cameroon)  [PDF]
Thomas Assokeng, Joseph Marie Siéliéchi, Guy Bertrand Noumi
Journal of Agricultural Chemistry and Environment (JACEN) , 2017, DOI: 10.4236/jacen.2017.64013
Abstract: The aim of this surveywas to identify the active ingredients of phytosanitary products generally used in the market-gardening, to evaluate the behavior of market gardeners, environmental and sanitary risks link to the use of phytosanitary products. Results revealed that 8 actives ingredients are regularly used: paraquat, atrazine, glyphosate, chlorpyrifos-éthyl, cypermethrin, maneb, mancozeb and diuron. The contamination of running water and rivers is caused by the fact that 81.25% of them are washing their pulverization equipments in these last ones. Moreover, 72.90% release empty packages of pesticides in the farm which will be carried away by running water. 59.09% adopt the overdose strategy in case of insufficient treatment. The inadequate equipment of protection and the consumption of surrounding water by 51.10% represent a danger for the health of market gardeners. Thus, headache and stomachache are the most recorded intoxications.
Fog-basking behaviour and water collection efficiency in Namib Desert Darkling beetles
Thomas N?rgaard, Marie Dacke
Frontiers in Zoology , 2010, DOI: 10.1186/1742-9994-7-23
Abstract: The beetles differ greatly in size. The largest P. cribripes has a dorsal surface area that is 1.39, 1.56, and 2.52 times larger than O. unguicularis, O. laeviceps, and S. gracilipes, respectively. In accordance with earlier reports, we found that the second largest O. unguicularis is the only one of the four beetles that assumes the head standing fog-basking behaviour, and that fog is necessary to trigger this behaviour. No differences were seen in the absolute amounts of fog water collected on the dorsal surface areas of the different beetles. However, data corrected according to the sizes of the beetles revealed differences. The better fog water harvesters were S. gracilipes and O. unguicularis while the large P. cribripes was the poorest. Examination of the elytra microstructures showed clear structural differences, but the elytra of all beetles were found to be completely hydrophobic.The differences in fog water harvesting efficiency by the dorsal surface areas of beetles with very different elytra surface structures were minor. We therefore conclude that the fog-basking behaviour itself is a more important factor than structural adaptations when O. unguicularis collect water from fog.The cold Benguela current runs along the South West African coast, creating one of the most arid habitats on earth; the Namib Desert [1]. Water is essential to all living organisms and this harsh environment presents a major challenge for all life forms. However, the cold coastal current not only suppresses rainfall over the desert, but is also the origin of fog that can reach as much as 100 km inland from the coast [2]. Fog brings water in the form of minute droplets that can deposit up to a litre of water per square metre on the mesh of an artificial fog screen during a day in the Namib Desert [3]. These fog events occur approximately 30 days per year in the inland desert [4], and represent a predictable source of water for the Namib Desert organisms [2].The Namib Desert has a r
Family caregivers of demented elderly people and access to medical care: Who gets worn out, why and what for?  [PDF]
Cyril Hazif-Thomas, Marie-Hélène Tritschler-LeMa?tre, Philippe Thomas
Open Journal of Psychiatry (OJPsych) , 2013, DOI: 10.4236/ojpsych.2013.32023
Abstract:

Demented persons in the process of slowly becoming dependent have to rely on the assistance of others. These others are health professionals (formal care), on the one hand and family carers (informal care) on the other hand. The latter, whether or not they have chosen to play a role which is hardly defined officially, have to face many difficult situations such as complicated access to care due to lack of equal opportunities under the health system, unable to support them efficiently. Taking care of a demented patient is a life challenge often leading to burn out, having impact on physical and mental health. Caregivers may thus even have no time or opportunity to take care of their own health. So, is it not high time for the decision-makers to think it over and take care of the carers by setting up programs and giving them the opportunity to learn, to work as a team with the professionals so as to protect themselves and their dignity as well as that of their patients. The difficulties/problems carers of demented patients may encounter should be a major issue for public health care because their role is a vital one and because the consequences which may have on their own health can be negative.

When It Helps, When It Hurts: Preliminary Results of Relationship Enhancement Education and The Hold Me Tight Program  [PDF]
Adam R. Fisher, Marie F. Stokey, Hiroshi M. Sasaki, Thomas L. Sexton
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.510137
Abstract:

Relationship education such as self-help and group interventions may be helpful for couples seeking to improve their relationships. This outcome study sought to provide preliminary data on the effectiveness of two interventions for couples, comparing the self-help book Hold Me Tight: Seven Conversations for a Lifetime of Love, to the 8-week relationship course, The Hold Me Tight Program: Conversations for Connection, which includes reading the book at home. Results suggest that reading the book alone may lead to positive change, attending the course in addition to reading the book may not result in as much change, and that participation in the course may have a potentially negative effect for less happy couples in the area of dyadic consensus. Results signify the importance of further research to understand the potential benefits as well as iatrogenic effects of relationship education.

Animal or Plant: Which Is the Better Fog Water Collector?
Thomas N?rgaard, Martin Ebner, Marie Dacke
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0034603
Abstract: Occasional fog is a critical water source utilised by plants and animals in the Namib Desert. Fog basking beetles (Onymacris unguicularis, Tenebrionidae) and Namib dune bushman grass (Stipagrostris sabulicola, Poaceae) collect water directly from the fog. While the beetles position themselves optimally for fog water collection on dune ridges, the grass occurs predominantly at the dune base where less fog water is available. Differences in the fog-water collecting abilities in animals and plants have never been addressed. Here we place beetles and grass side-by-side in a fog chamber and measure the amount of water they collect over time. Based on the accumulated amount of water over a two hour period, grass is the better fog collector. However, in contrast to the episodic cascading water run-off from the grass, the beetles obtain water in a steady flow from their elytra. This steady trickle from the beetles' elytra to their mouth could ensure that even short periods of fog basking – while exposed to predators – will yield water. Up to now there is no indication of specialised surface properties on the grass leafs, but the steady run-off from the beetles could point to specific property adaptations of their elytra surface.
