Biliobronchial fistula secondary to percutaneous dilatation of the benign biliary stricture
Authors: Colovic Radoje , Grubor Nikica , Kaitovic Marko , Latincic Stojan , Colovic Natasa
Published: January 2013

Introduction. Biliobronchial fistula is rare. Very rarely it may be
congenital, more frequently it is acquired as a complication of the hydatide
cyst of the liver, pyogenic abscess, serious trauma and resection of the
liver as well as recurrent cholangitis due to benign bile duct stricture or
cholangiolithiasis. The main causes of the biliobronchial fistula are
billiary obstruction and infectious lesion (abscess) in the liver. Case
Outline. We present a 56-year-old man with benign stricture of the
hepaticojejunostomy performed after operative common bile duct injury, who
developed biliobronchial fistula following repeated percutaneous drainage of
the liver abscess and percutaneous dilatation of the strictured anastomosis.
Over the years the patient developed atrophy/hypertrophy complex, portal
hypertension, grade II esophageal varicosities, ascites and splenomegaly.
Although biliobronchial fistula was solved by a successful surgical
reconstruction (new wide hepaticojejunostomy), the operation had a limited
value as it was performed late after permanent lesions of the liver and
intrahepatic bile ducts had already developed. Conclusion. Surgical
reconstruction of strictured biliodigestive anastomosis should be considered
on time as a possibly better solution than percutaneous dilatation. According
to the authors? knowledge, a similar case of biliobronchial fistula as a
complication of percutaneous dilatation of the benign biliary stricture has
not been reported before in the literature.

Published: January 2013

Introduction. Klippel?Tr?naunay syndrome (KTS) is a very rare congenital
anomaly of blood vessels, characterized by the following clinical triad:
varicose superficial veins, port-wine stain and usually bony and soft tissue
hypertophy of extremities, most often located in the lower extremities. It is
often accompanied by visceral manifestations, and rarely combined with
splenomegaly. Case Outline. A 30-year-old female patient came to the Surgery
Clinic because of occasional left hypochondrial pain. After she was diagnosed
with KTS combined with splenomegaly, splenectomy was performed. Macroscopic
and microscopic spleen examination indicated the presence of tumor of
vascular origin, presenting a combination of lymphangioma and hemangioma.
Conclusion. Diagnosed KTS demands a thorough clinical examination of the
patient because of the potential presence of visceral manifestations. When
splenomegaly is present, even though being often benign, splenectomy is
usually performed to alleviate accompanying symptoms which occur as a result
of organ enlargement and compression, to prevent rupture and consequential
bleeding when the vascular spleen tumor is large, and finally to avoid a
possibility of malignant transformation.
Manifestations of contact allergy
Authors: Jovanovic Marina
Published: January 2013

Contact allergy (sensibilization, hypersensitivity) is a state of specific
immune response in the skin occurring after repeated contact of the skin or
mucous membrane with various environmental substances. At the Allergy
Department of the Clinic of Dermatovenereology Diseases in Novi Sad, we patch
tested the patients who were referred with a suspected contact allergy and
who had been also coming for check-ups as outpatients over the last two
years. Contact allergy was assessed in respect to the fact that not only
allergic contact dermatitis, but also the whole spectrum of different
clinical entities where allergic contact dermatitis and contact urticaria are
only the two extremes, should be included. Our results provide further
insight into etiology and pathogenesis of contact allergy, offering a better
diagnostic and therapeutic approach to patients and opening new horizons to
further researches.

Published: January 2013

Endovascular aortic/aneurysm repair (EVAR) was introduced into clinical
practice at the beginning of the nineties. Its fast development had a great
influence on clinicians, vascular surgeons and interventional radiologists,
educational curriculums, patients, industry and medical insurance. The aim of
this paper is to present the contribution of clinicians and industry to the
development and advancement of endovascular aortic repair over the last 20
years. This review article presents the development of EVAR by focusing on
the contribution of physicians, surgeons and interventional radiologists in
the creation of the new field of vascular surgery termed hybrid vascular
surgery, and also the contribution of technological advancement by a
significant help of industrial representatives ? engineers and their
counselors. This article also analyzes studies conducted in order to compare
the successfulness of EVAR with up-to-now applied open surgical repair of
aortic aneurysms, and some treatment techniques of other aortic diseases.
During the first two decades of its development the EVAR method was rapidly
progressing and was adopted concurrently with the expansion of technology.
Owing to large randomized studies, early and long-term results indicate
specific complications of this method, thus influencing further technological
improvement and defining risk patients groups in whom the use of the
technique should be avoided. Good results are insured only in centers,
specialized in vascular surgery, which have on their disposal adequate
conditions for solving all complications associated with this method.
Fifty years of subclinical primary aldosteronism: Importance of early diagnosis
Authors: Ciric Jasmina , Zarkovic Milos , Beleslin Biljana
Published: January 2013

Clinical presentation of excessive aldosterone secretion is often not
specific. The presence of resistant severe hypertension (HT) and signs of
hypokalemia is useful but inconsistent characteristic. Plasma aldosterone
level in primary aldosteronism (PA) could be normal, although inappropriately
high for a low plasma renin activity and not suppressed by sodium. Screening
of hypertensive population with no obvious signs of PA has revealed an
increased prevalence of idiopathic adrenal hyperplasia as a cause of
aldosterone excess. Nowadays, PA is the most common endocrine form of
secondary HT, with an estimated prevalence 5-10% of hypertensive population.
The diagnosis of PA can lead to surgical cure in the case of aldosterone
producing adenoma and unilateral adrenal hyperplasia. The aldosterone excess
is responsible for vascular inflammation and end-organ damage. Left
ventricular hypertrophy, cardiac arrhythmia and cerebral insult are
frequently seen in PA and preventable by mineralocorticoid receptor blockers.
For this reason, screening for PA in patients with HT and hypokalemia and/or
adrenal incidentaloma, resistant and severe HT, and in patients with the
onset of HT at young age is advisable. The most widely accepted screening for
PA is serum aldosterone to plasma rennin activity (aldosterone : PRA) ratio,
with the cut-off of 30 ng/dl:ng/ml/h. Serum aldosterone level could be
included as an additional screening parameter. Confirmatory tests are crucial
for the diagnosis of PA in patients with an increased aldosterone : PRA ratio
and subtype differentiation for the choice of treatment.

Optimal wavelength selection algorithm of non-spherical particle size distribution based on the light extinction data
Authors: Tang Hong
Published: January 2013

In this paper, the anomalous diffraction approximation method is improved for
calculating the extinction efficiency of non-spherical particles. Through
this step, the range of the refractive index of particles can be enlarged,
and the improved anomalous diffraction approximation method can be applied
easily to the calculation of extinction efficiency for the most kinds of
non-spherical particles. Meanwhile, an optimal wavelength selection algorithm
is proposed for the inversion of non-spherical particle size distribution in
the dependent mode. Through the improved anomalous diffraction approximation
method, the computation time is substantially reduced compared with the
rigorous methods, and a more accurate inversion result of particle size
distribution is obtained using the optimal wavelength selection method.
A new method for fiber orientation distribution in a planar contracting turbulent flow
Authors: Yang Wei
Published: January 2013

A new Euler model is proposed to predict fiber orientation distribution at
high Reynolds number in a dilute planar contraction. The model mainly
accounts for the evolution of mean velocity and turbulence-induced rotational
diffusion coefficient along the contraction. It is shown that the new model,
as the function of local turbulent dissipation rate, fiber length, and fluid
viscosity, can reflect the subtle change of fiber orientation accurately.
Retrieval of spherical particle size distribution with an improved Tikhonov iteration method
Authors: Tang Hong
Published: January 2013

The problem of retrieval for spherical particle size distribution in the
independent mode is studied, and an improved Tikhonov iteration method is
proposed. In this method, the particle size distribution is retrieved from
the light extinction data through the Phillips-Twomey method firstly in the
independent mode, and then the obtained inversion results of the particle
size distribution is used as the initial distribution and the final retrieved
particle size distribution is obtained. Simulation experiments indicate that
the spherical particle size distributions obtained with the proposed method
coincide fairly well with the given distributions.
Simulation of flow past two tandem cylinders using deterministic vortex method
Authors: Huang Guo , Huan Haiming , Xu Xiaoliang , Liu Yu
Published: January 2013

The vortex method is a direct numerical simulation method for solving the
Navier-Stokes equations. In order to reveal the influence of Reynolds number
and distances between the cylinders, the incompressible flow past a pair of
tandem cylinders is solved on the base of the vortex method. The results show
that for the flow past two tandem cylinders, there is a critical distance of
the tandem cylinders. Over the critical distance, the flow field will have a
sudden change, and the drag coefficient, lift coefficient and Strouhal number
will also change dramatically. The critical distance will diminish as the
Reynolds number rises.
The fractal harmonic law and its application to swimming suit
Authors: Kong Hai-Yan , He Ji-Huan
Published: January 2013

Decreasing friction force between a swimming suit and water is the key factor
to design swimming suits. Water continuum mechanics forbids discontinuous
fluids, but in angstrom scale water is indeed discontinuous. Swimming suit is
smooth on large scale, but it is discontinuous when the scale becomes
smaller. If fractal dimensions of swimming suit and water are the same, a
minimum of friction force is predicted, which means fractal harmonization. In
the paper, fractal harmonic law is introduced to design a swimsuit whose
surface fractal dimensions on a macroscopic scale should be equal to or
closed to the water's fractal dimensions on an Angstrom scale. Various
possible microstructures of fabric are analyzed and a method to obtain
perfect fractal structure of fabric is proposed by spraying nanofibers to its
surface. The fractal harmonic law can be used to design a moving surface with
a minimal friction.

Authors: Xing Tie-Ling , Liu Jie , Li Shi-Wei , Chen Guo-Qiang
Published: January 2013

Thermal properties of flame retardant cotton fabric grafted by dimethyl
methacryloy-loxyethyl phosphate were investigated by the atom transfer
radical polymerization method. Thermal gravimetric analysis was used to
explore the thermal decomposition mode of flamed retardant cotton fabric. The
weight loss rate of the flamed retardant cotton was bigger than that of the
control cotton fabric, and a more final residual char of flamed retardant
cotton was also observed. Flammability tests were used to study the flame
retardance property of the flame retardant cotton fabric. The results showed
that flamed retardant cotton fabric with 16.8% of weight gain could keep good
flame retardance. Scanning electron microscope pictures were applied to
investigate the morphology of residual char of the flame retardant samples.

Published: January 2013

As a typical mathematical model in fluids and plasmas, Korteweg-de Vries
equation is famous. In this paper, the Exp-function method is extended to a
nonisos-pectral Korteweg-de Vries type equation with three variable
coefficients, and multi-wave solutions are obtained. It is shown that the
Expfunction method combined with appropriate ansatz may provide with a
straightforward, effective and alternative method for constructing multi-wave
solutions of variable-coefficient non-linear evolution equations.

Authors: Zhang Kai , Tian Fu-Zhen , Yu Ming-Zhou
Published: January 2013

The induced-charge elecetroosmosis around conducting/Janus cylinder with
arbitrary Debye thickness is studied numerically, when an direct current weak
electric filed is suddenly applied in a confined microchannel. It?s found
that there are four large circulations around the conducting cylinder, and
the total flux in the microchannel is zero; there are two smaller
circulations around the Janus cylinder, and they are compressed to wall. A
bulk flux, which has a parabolic relation with the applied electric field, is
also predicted.
Study on reverse-quadtree adaptive grid technique

Published: January 2013

The fast multipole method is universally adopted for solving the convection
equation in the vortex method. In this paper, a reverse-quadtree adaptive
grid technique is proposed in order to improve the quadtree adaptive grid
technique in the fast multipole method. Taking flow past a cylinder as an
example, the results indicate the reverse-quadtree scheme can save more
calculation time than the quadtree scheme when the particle population is
large enough.
A novel friction law
Authors: Kong Hai-Yan , He Ji-Huan
Published: January 2013

Frictional force is a vitally important factor in the application of
engineering either in macroscopic contacts or in micro/nanoscale contacts.
Understanding of the influencing factors about frictional force is essential
for the design of miniaturized devices and the use of minimal friction force.
In the paper, dimensional analysis is used to analysis factors relative to
frictional force. We show that the frictional force scales with where A is
the contact area and N is the normal contact force. An experiment is carried
out to verify the new friction law.

Lithologic and morphometric characteristics of the Chure River Basin, Central Nepal
Authors: Tamrakar Naresh Kazi , Khakurel Dharmendra
Published: January 2013

The Chure River Basin (CRB) is a small basin (width 5.75 km, length 9.74 km, perimeter 32.35 km and area 35.23 km2) with three sub-watersheds, and is crossed by the Tribhuvan Highway that may be threatened by riverine and allied processes. The geology and morphometry of the basin were studied to search for status of the basin development andriver dynamism. The Chure River is a sixth order river fed by rainstorm, and has length ratio of 2.79, indicating nearly three times the average length of its fifth order segment, showing notable competency. The mean bifurcation ratio of the Chure River is 3.20, showing immature nature of the CRB. Drainage texture (DT) varies from moderate (0.64–0.96) to very fine (0–0.32). The Chure River is sinuous (K =1.18).The relative relief (RR) is moderately low (15–30) to moderately high (120–240) and dissection index (DI) is moderate (0.2–0.3) to high (0.3–0.4). The CRB carries varied lithology; gravelly to coarse sandy and medium sandy and muddy, from the north to the south extension of the basin. Fine to very fine DT found in large areas because of loosely consolidated and soft lithology. Even where rocks are stiff, the presence of discontinuity has perhaps influenced the DT. Very fine to fine DT coupled with elongate nature of the basin (as indicated by low value of form factor, 0.37) is vulnerable to greater competency of the river during high rainfall.RR slope and DI are found to be high in the cliff- forming lithology (stiff and well cemented), and low in other areas. High dissection, high slopes and high relief show active and immature nature of the CRB, indicating susceptibility of further incision of the Siwalik Hills and aggravation of erosion and slope movements by the immature rivers in the CRB. Presence of knick points along the river profile reflects affinity of the river to incision. The sinuosity, radius of curvature, and bifurcation ratio, all indicate immaturity of the basin. The hypsometric analysis indicates inverse relationship between the elevation and the cumulative %area, showing active erosional condition of the basin.

Petrology and genesis of the Bhainskati iron ore deposit of Palpa District, western Nepal
Authors: Devkota Sujan , Paudel Lalu Prasad
Published: January 2013

The Bhainskati Formation of the Tansen Group in the Palpa area is known for hematite iron ore deposit for long time. A prominent band of hematite of about 1-2 m thickness and extending >5 km was identified in the upper part of the Bhainskati Formation in the present study. The band is repeated three times in the area by folding and faulting. Petrographic study shows that it is oolitic ironstone of sedimentary origin. Main minerals in the band are hematite, goethite, quartz, calcite, siderite and albite. Hematite content varies considerably among samples and occurs mainly as oolite and cement. The Bhainskati ironstone with its ferrous mineral assemblage and well-rounded texture of the ooids suggests shallow marine environment (prodeltaic to estuarine) with reduced clastic input.

Landslide susceptibility analysis using decision tree method, Phidim, Eastern Nepal
Authors: Poudyal Chandra Prakash
Published: January 2013

The decision tree is one of the new methods used for the determination of landslide susceptibility in the study area. The Phidim area is selected for the application of this method. The total surface area is 168.07 sq. km, and is located at the eastern part of Nepal. There are total of 10 different data bases used for this study which are; geological formation, elevation, slope, curvature, aspect, stream power index, topographic wetness index, distance from drainage, lineaments, and slope length, and are considered as landslide conditioning factors. Geographical information system (GIS) is used as basic tools and ARC/View is used for the processing data analysis and final map preparation. For the decision tree analysis the PASW 18 (statistical tool) is used to generate values of each factor. According to the results of decision tree, two geological formations; stream power index and slope are found as the most effective parameters on the landslide occurrence in the study area. Using the predicted values, the landslide susceptibility map of the study area is produced. To assess the performance of the produced susceptibility map, the area under curve (AUC) is drawn. The AUC value of the produced landslide susceptibility map has been obtained as 95.9%. According to the results of the AUC evaluation, the produced map has showed a good performance. As to wrap up, the produced map is able to be used for medium scaled and regional planning purposes.

“Keep the Home Fires Burning“: Fairy Tale Heroes and Heroines in an East German Heimat
Authors: Fritzsche Sonja
Published: January 2013

The article argues that the films Das kalte Herz (The Cold Heart, 1950) and Der Teufel von Mühlenberg (The Devil of Mill Mountain, 1955) functioned in two ways-as fairy tales and also as new Heimat or “homeland“ tale. Besides Wolfgang Staudte's The Story of Little Mook, these two films were the only two live action fairy tale films that appeared before East Germany's DEFA made its first Grimm feature adaptation in 1956, The Brave Little Tailor. Yet, unlike the Grimm-based films that take place in a generic “forest,“ these first two films take place explicitly in the Black Forest and the Harz Mountains, two locations synonymous with the beauty and timeless nature of past notions of German Heimat. The two films also engaged with the growing monetary and symbolic success of the West's postwar Heimatfilme or homeland films. The article focuses on how The Cold Heart and Mill Mountain contributed to the rearticulation of the emerging Heimat discourse in the early German Democratic Republic, with a particular focus on gender.
A Discipline Refuses: Rating Academic Research Performance in Germany
Authors: Bendix John
Published: January 2013

The ability to conduct academic research is partly a function of the time

available for it, especially relative to teaching and administrative obligations.

1 For the last decade, both the number of students enrolled at German

universities and the number of full-time professors has remained at

about the same level. The number of wissenschaftliche Mitarbeiter, doctorallevel

research assistants, however, has increased by more than half, and

the number of Lehrbeauftragte, those on temporary teaching contracts, has

increased by three-quarters. There is thus no lack of personnel to help

professors meet teaching or administrative obligations, or to assist on

research projects.2 Nevertheless, and particularly in the humanities, German

professors complain about their teaching burdens, about added

administrative tasks their universities place upon them,3 and about what

they see as new pressures to bring in funding or produce results.4 That the

Historikertag, the biannual meeting of German historians, had “Boundaries”

(2010) and “Resources—Conflicts” (2012) as the overarching themes

for its last two meetings seems in keeping with this sentiment.
Registration of CA 4002 Cotton Germplasm Line Partially Resistant to Verticillium Wilt
Authors: Dever Jane K. , Wheeler Terry A. , Kelly Carol M.
Published: January 2013

Verticillium wilt (caused by Verticillium dahliae Kleb.) is a devastating global disease and an emerging production issue in the primary cotton (Gossypium hirsutum L.) region of the United States, the Texas High Plains. Lines with partial resistance generally are not suited to this region on the basis of later crop maturity and boll type. A major objective of the Texas AgriLife Research cotton breeding program is combining partial resistance to Verticillium wilt with early crop maturity and storm‐proof boll type. CA 4002 cotton germplasm (Reg. No. GP‐956, PI 665226) was derived from a 1994 cross of ‘Paymaster 147’ (PVP 8900269, PI 601733) with (Stahman P × CA 2266). Three years of multilocation replicated performance testing were conducted in 2009, 2010, and 2011. CA 4002 was the most resistant to Verticillium wilt in three inoculated greenhouse assays (33 entries) and was among the most resistant entries in a field site naturally infested with V. dahliae (30 entries). CA 4002 was similar to the partially resistant check in all greenhouse and field ratings for disease incidence and was more resistant than the partially susceptible check in all greenhouse and field tests. Performance trial data across 3 yr indicate that CA 4002 is similar to the best production check cultivar in yield, maturity, and boll type and similar to the most resistant check in Verticillium wilt resistance. CA 4002 had better fiber length uniformity and elongation than both checks.
Computational Study on a PTAS for Planar Dominating Set Problem
Authors: Marzban Marjan , Gu Qian-Ping
Published: January 2013

The dominating set problem is a core NP-hard problem in combinatorial optimization and graph theory, and has many important applications. Baker [JACM 41,1994] introduces a k-outer planar graph decomposition-based framework for designing polynomial time approximation scheme (PTAS) for a class of NP-hard problems in planar graphs. It is mentioned that the framework can be applied to obtain an O(2ckn) time, c is a constant, (1+1/k)-approximation algorithm for the planar dominating set problem. We show that the approximation ratio achieved by the mentioned application of the framework is not bounded by any constant for the planar dominating set problem. We modify the application of the framework to give a PTAS for the planar dominating set problem. With k-outer planar graph decompositions, the modified PTAS has an approximation ratio (1 + 2/k). Using 2k-outer planar graph decompositions, the modified PTAS achieves the approximation ratio (1+1/k) in O(22ckn) time. We report a computational study on the modified PTAS. Our results show that the modified PTAS is practical.

Reduced graphene oxide–carbon nanotube (RGO–CNT) hybrid materials were prepared by a simple catalyst-free route. The thermostability, photoluminescence (PL) and electrical properties of RGO–CNTs were investigated systematically. The results revealed that compared to RGO, RGO–CNTs showed multicolor PL, and higher thermostability and conductivity. The RGO–CNTs therefore have important potential applications in the fields of photonic and electrical devices.

Authors: Wu Yan-Bin , Zheng Li-Jun , Yi Jun , Wu Jian-Guo , Chen Ti-Qiang , Wu Jin-Zhong
Published: January 2013

A simple and reliable method of high-performance liquid chromatography with photodiode array detection (HPLC-DAD) was developed to evaluate the quality of Receptaculum Nelumbinis (dried receptacle of Nelumbo nucifera) through establishing chromatographic fingerprint and simultaneous determination of five flavonol glycosides, including hyperoside, isoquercitrin, quercetin-3-O-β-d-glucuronide, isorhamnetin-3-O-β-d-galactoside and syringetin-3-O-β-d-glucoside. In quantitative analysis, the five components showed good regression (R > 0.9998) within linear ranges, and their recoveries were in the range of 98.31%–100.32%. In the chromatographic fingerprint, twelve peaks were selected as the characteristic peaks to assess the similarities of different samples collected from different origins in China according to the State Food and Drug Administration (SFDA) requirements. Furthermore, hierarchical cluster analysis (HCA) was also applied to evaluate the variation of chemical components among different sources of Receptaculum Nelumbinis in China. This study indicated that the combination of quantitative and chromatographic fingerprint analysis can be readily utilized as a quality control method for Receptaculum Nelumbinis and its related traditional Chinese medicinal preparations.
Self-Assembly of Discrete Metal Complexes in Aqueous Solution via Block Copolypeptide Amphiphiles
Authors: Kuroiwa Keita , Masaki Yoshitaka , Koga Yuko , Deming Timothy
Published: January 2013

The integration of discrete metal complexes has been attracting significant interest due to the potential of these materials for soft metal-metal interactions and supramolecular assembly. Additionally, block copolypeptide amphiphiles have been investigated concerning their capacity for self-assembly into structures such as nanoparticles, nanosheets and nanofibers. In this study, we combined these two concepts by investigating the self-assembly of discrete metal complexes in aqueous solution using block copolypeptides. Normally, discrete metal complexes such as [Au(CN)2]−, when molecularly dispersed in water, cannot interact with one another. Our results demonstrated, however, that the addition of block copolypeptide amphiphiles such as K183L19 to [Au(CN)2]− solutions induced one-dimensional integration of the discrete metal complex, resulting in photoluminescence originating from multinuclear complexes with metal-metal interactions. Transmission electron microscopy (TEM) showed a fibrous nanostructure with lengths and widths of approximately 100 and 20 nm, respectively, which grew to form advanced nanoarchitectures, including those resembling the weave patterns of Waraji (traditional Japanese straw sandals). This concept of combining block copolypeptide amphiphiles with discrete coordination compounds allows the design of flexible and functional supramolecular coordination systems in water.
Single Grain Boundary Modeling and Design of Microcrystalline Si Solar Cells
Authors: Lin Chu-Hsuan , Hsu Wen-Tzu , Tai Cheng-Hung
Published: January 2013

For photovoltaic applications, microcrystalline silicon has a lot of advantages, such as the ability to absorb the near-infrared part of the solar spectrum. However, there are many dangling bonds at the grain boundary in microcrystalline Si. These dangling bonds would lead to the recombination of photo-generated carriers and decrease the conversion efficiency. Therefore, we included the grain boundary in the numerical study in order to simulate a microcrystalline Si solar cell accurately, designing new three-terminal microcrystalline Si solar cells. The 3-μm-thick three-terminal cell achieved a conversion efficiency of 10.8%, while the efficiency of a typical two-terminal cell is 9.7%. The three-terminal structure increased the JSC but decreased the VOC, and such phenomena are discussed. High-efficiency and low-cost Si-based thin film solar cells can now be designed based on the information provided in this paper.
Hydrothermal Synthesis and Characterization of Ni-Al Montmorillonite-Like Phyllosilicates
Authors: Reinholdt Marc , Brendlé Jocelyne , Tuilier Marie-Hélène , Kaliaguine Serge , Ambroise Emmanuelle
Published: January 2013

This work describes the first hydrothermal synthesis in fluoride medium of Ni-Al montmorillonite-like phyllosilicates, in which the only metallic elements in the octahedral sheet are Ni and Al. X-ray diffraction, chemical analysis, thermogravimetric and differential thermal analysis, scanning electron microscopy and transmission electron microscopy confirm that the synthesized samples are montmorillonite-like phyllosilicates having the expected chemical composition. The specific surface areas of the samples are relatively large (>100 m2 g−1) compared to naturally occurring montmorillonites. 29Si and 27Al nuclear magnetic resonance (NMR) indicate substitutions of Al for Si in the tetrahedral sheet. 19F NMR and Ni K-edge extended X-ray absorption fine structure (EXAFS) local probes highlight a clustering of the metal elements and of the vacancies in the octahedral sheet of the samples. These Ni-Al phyllosilicates exhibit a higher local order than in previously synthesized Zn-Al phyllosilicates. Unlike natural montmorillonites, where the distribution of transition metal cations ensures a charge equilibrium allowing a stability of the framework, synthetic montmorillonites entail clustering and instability of the lattice when the content of divalent element in the octahedral sheet exceeds ca. 20%. Synthesis of Ni-Al montmorillonite-like phyllosilicates, was successfully achieved for the first time. These new synthetic materials may find potential applications as catalysts or as materials with magnetic, optical or staining properties.

Published: January 2013

We report on single mode optical transmission of hollow core glass waveguides (HWG) coupled with an external cavity mid-IR quantum cascade lasers (QCLs). The QCL mode results perfectly matched to the hybrid HE11 waveguide mode and the higher losses TE-like modes have efficiently suppressed by the deposited inner dielectric coating. Optical losses down to 0.44 dB/m and output beam divergence of ~5 mrad were measured. Using a HGW fiber with internal core size of 300 µm we obtained single mode laser transmission at 10.54 µm and successful employed it in a quartz enhanced photoacoustic gas sensor setup.

The in-service Hakka rammed earth buildings, in the Fujian Province of China, are unique in design and performance. Their UNESCO’s inscription as World Heritage sites recognizes their artistic, cultural, social and historic significance. Sponsored by the National Science Foundation of the United States, the authors have examined the engineering values of these buildings in terms of comfortable living at low energy consumption, sustainability and durability. The objective of this study was to better understand the thermo-mechanical and aging responses of Hakka earth buildings under thermal and earthquake loads through nondestructive field evaluation, including full-scale roof truss and floor testing, laboratory testing of field samples and finite element modeling. This paper presents our observations and findings from the field nondestructive evaluations with emphasis on the integrity of the rammed earth outer walls and inner wood structures, as well as the thermal comfort of living in these buildings, while a second paper presents the results from the material characterization of field samples and the structural responses of a representative building under earthquake induced loads through finite element analysis.
Interpreting motion and force for narrow-band intermodulation atomic force microscopy
Authors: Platz Daniel , Forchheimer Daniel , Tholén Erik A , Haviland David B
Published: January 2013

Intermodulation atomic force microscopy (ImAFM) is a mode of dynamic atomic force microscopy that probes the nonlinear tip–surface force by measurement of the mixing of multiple modes in a frequency comb. A high-quality factor cantilever resonance and a suitable drive comb will result in tip motion described by a narrow-band frequency comb. We show, by a separation of time scales, that such motion is equivalent to rapid oscillations at the cantilever resonance with a slow amplitude and phase or frequency modulation. With this time-domain perspective, we analyze single oscillation cycles in ImAFM to extract the Fourier components of the tip–surface force that are in-phase with the tip motion (FI) and quadrature to the motion (FQ). Traditionally, these force components have been considered as a function of the static-probe height only. Here we show that FI and FQ actually depend on both static-probe height and oscillation amplitude. We demonstrate on simulated data how to reconstruct the amplitude dependence of FI and FQ from a single ImAFM measurement. Furthermore, we introduce ImAFM approach measurements with which we reconstruct the full amplitude and probe-height dependence of the force components FI and FQ, providing deeper insight into the tip–surface interaction. We demonstrate the capabilities of ImAFM approach measurements on a polystyrene polymer surface.

Background:

Junín virus (JUNV) and several other clade B New World arenaviruses cause human disease ranging from mild febrile illness to severe viral haemorrhagic fever. These viruses pose a significant threat to national security and safe and effective therapies are limited except in Argentina, where immune plasma is the standard of care for treating JUNV infection in cases of Argentine haemorrhagic fever.

Methods:

An in vitro screen of the Chemtura library identified several compounds with activity against Tacaribe virus (TCRV), a clade B arenavirus closely related to JUNV. Of these compounds, D746, a phenolic dibenzylsulfide, was further pursued for additional in vitro studies and evaluated in the AG129 mouse TCRV infection model.

Results:

D746 was found to act during an early to intermediate stage of the TCRV replication cycle and μM range activity was confirmed by virus yield reduction assays with both TCRV and JUNV. Although intraperitoneal twice daily treatment regimens were found to be highly effective when started 2 h prior to TCRV challenge in AG129 mice, post-exposure treatment initiated 3 days after infection was not efficacious. Interestingly, despite the pre-exposure treatment success, D746 did not reduce serum or tissue virus titres during the acute infection. Moreover, D746 elicited ascites fluid accumulation in mice during, as well as independent of, infection.

Conclusions:

Our findings suggest that D746 may be altering the host response to TCRV infection in AG129 mice in a way that limits pathogenesis and thereby protects mice from otherwise lethal infection in the absence of measurable reductions in viral burden.
Vérité et illusion des approches croisées entre psychanalyse et neurosciences
Authors: Potier Rémy
Published: January 2013

Résumé Les approches croisées entre neurosciences et psychanalyse sont de plus en plus défendues sur le plan méthodologique. À l’occasion de ce numéro de la revue Adolescence , Rémy Potier interview Roland Gori à propos de l’heuristique de ces nouvelles recherches. La rigueur conceptuelle semble souvent faire défaut à ces approches qui ne se soucient pas suffisamment de la polysémie des concepts comme des enjeux sociaux-historiques.
Introduction

Résumé Reprendre les thèses de La Société du malaise (2010) dans le champ de l’adolescence et de la jeunesse est l’objectif de cette journée de travail avec A. Ehrenberg. L’individu doit non seulement s’appuyer sur ses capacités personnelles, compétence en particulier, mais sur « sa subjectivité, son intériorité ». « La subjectivité individuelle (“ libérée ”) est sur le devant de la scène. » Nous proposons à la méthodologie de l’auteur de faire appel non pas exclusivement aux pathologies de caractère comme cela lui est habituel mais à l’adolescence en tant qu’ensemble processuel de création et, haut lieu bien connu d’individuation narcissique. Comment le double mouvement solidaire de désinstitutionnalisation des rapports sociaux et de psychologisation fait-il souffrir, peut-être de façon exemplaire, les adolescents en leurs normalités supposées et en leurs pathologies contemporaines ? Comment cette évolution change-t-elle la jeunesse en retour ?
La société du malaise
Authors: Ehrenberg Alain
Published: January 2013

Résumé Le « malaise dans la société » est moins un point de départ de l’analyse sociologique qu’un problème à élaborer et à clarifier. L’auteur propose de remplacer l’idée individualiste que la société cause des souffrances psychiques par l’idée sociologique que la souffrance psychique est aujourd’hui une forme d’expression obligatoire, c’est-àdire attendue, du mal social. Cela le conduit à l’hypothèse qu’avec la santé mentale, on assiste à une généralisation de l’usage d’idiomes personnels pour donner forme et résoudre des conflits de relations sociales. Ces jeux de langage consistent à mettre en relation malheur personnel et relations sociales perturbées à l’aune de la souffrance psychique, unissant ainsi le mal individuel et le mal commun. À partir de là, il développe l’hypothèse que, brouillée dans le malaise, se joue une crise de l’égalité à la française, c’est-à-dire d’une égalité conçue essentiellement dans les termes de la protection, et une protection en termes de statut, sur le modèle de la fonction publique, alors que l’égalité d’aujourd’hui, et donc la lutte contre les inégalités sociales, se joue dans les termes de la capacité.
Adolescents et société : remarques sur les aménagements névrotiques et leur évolution dans le temps
Authors: Marcelli Daniel
Published: January 2013

Résumé La subjectivation, caractéristique du travail psychique de l’adolescence, est avant tout une appropriation par le sujet de son corps et de sa pensée. Ce travail psychique est paradigmatique des croyances sociales que nous partageons : les symptômes et plus encore les défenses psychiques évoluent incontestablement avec le temps, par delà l’inconscient dont on peut penser qu’il est hors du temps. Ainsi, l’expression symptomatique est constamment prise dans l’évolution des valeurs sociales.
L'urgence à l'adolescence
Authors: Guedj Marie-Jeanne
Published: January 2013

Résumé À partir de l’expérience d’un centre d’urgences psychiatriques générales accueillant chaque année 700 jeunes de moins de dix-huit ans, et à la suite de l’article d’Henri Flavigny de 1984 sur les réponses en urgence à l’adolescence, des voies de réflexion sont proposées. L’urgence est actuellement un phénomène de société s’exacerbant dans des crises. Nous préférons parler de crise à l’adolescence, processus à la fois intrinsèque et environnemental, pouvant ou non aboutir au service des urgences, de même qu’une urgence se déclinera ou non en crise. La temporalité complexe tant de l’adolescence que de l’urgence est abordée. La paranoïa y est activée, parfois la seule modalité de questionnement du faux quand le compromis est impossible. Ainsi l’urgence apparaîtelle comme le réceptacle de l’impossible adolescence quand la subjectivité est en impasse. Elle se dévoile de façon inattendue comme un endroit de parole et d’écoute.
Trangresser ou transcrire

Résumé Lorsque l’auteur (M. Hatzfeld) parle de la « vitalité sauvage » jaillissant dans le sillage de la jeunesse, je pense que les processus d’adolescence sont le vivant de la jeunesse ; sublimation pubertaire bien à tort interprétée par la réponse sociale comme transgression. La liberté créatrice, concevons-la ainsi n’est jamais seule.
Appelle-moi seulement amour et je serai rebaptisé
Authors: Rojas-Urrego Alejandro
Published: January 2013

Résumé L’état amoureux à l’adolescence prend souvent la forme de la passion et les accents d’une tragédie. Il est aussi craint que recherché, non seulement en tant que retrouvaille et répétition, « réédition de faits anciens » écrit Freud, mais aussi en tant que découverte nouvelle, dynamisme créateur, invention transformatrice. Il représente désormais un second baptême, une nouvelle naissance qui doit parfois dénier la première. Aimer, c’est renaître. Se défaire, afin de mieux se refaire, se recréer. Au risque, bien entendu, de se perdre pour toujours. L’état amoureux à l’adolescence s’impose à l’attention du psychanalyste. L’expérience clinique nous confronte parfois aux effondrements psychiques qui suivent les déceptions amoureuses. Elles sont alors les révélateurs de la qualité des assises narcissiques des adolescents dont l’identité est en souffrance. Reviviscence plus que réminiscence. Dans ces situations où les représentations viennent à nous manquer, la littérature nous est souvent d’un grand secours. Elle peut nous permettre de commencer à mettre en mots une histoire qui n’en a pas. À partir de l’étude de Roméo et Juliette de W. Shakespeare, l’auteur propose plusieurs lignes d’interprétation possibles de l’amour à l’adolescence autour des notions de corps sexuel, de narcissisme, de mort, d’orgasme, de nom.
« I accuse »
Authors: Gutton Philippe
Published: January 2013

Résumé La pensée ou le fonctionnement paranoïaque a une certaine spécificité au sein des processus d’adolescence. Elle serait une limite ordinaire ou pathologique imposée à leur créativité, limite inscrite dès le pictogramme pubertaire dont le déroulement ne se fait pas avec l’Autre mais contre l’Autre. La base sur laquelle s’effectue la création adolescente est l’état d’illusion pubertaire au sens winnicottien au sein duquel le « moi infantile » et le « non encore-moi pubertaire » sont en paradoxalité. La paranoia serait l’effet d’une injonction paradoxale venue du sujet et de son environnement attaquant l’état d’illusion fondamental. À partir de cette thèse sont compris les traits de la paranoia adolescente : pensée causaliste, couple déni-projection, accusation du corps génital. Le dernier chapitre cherche les corollaires possibles de cette thèse pour la cure adolescente afin de contourner l’obstacle paranoïaque : travail dans la mesure du possible de l’ordre de la pensée associative, refus de l’opposition dedans-dehors au bénéfice d’une mutualité à l’intérieur de la séance prise comme observatoire des événements extérieurs régulièrement relatés par l’adolescent, importance du contre-transfert provocateur du transfert positif.
The ineluctable mystical passion of the adolescent
Authors: Lesourd Serge
Published: January 2013

Résumé Le temps psychique de l’adolescence confronte nécessairement le sujet à la désidéalisation des dieux infantiles, ceux que l’enfant se crée du fait de sa dépendance fondamentale. Or le lien social postmoderne a changé le statut des dieux sociaux, faisant de la passion mystique adolescente non plus une « assomption » symbolique de ceux-ci, sous la forme d’un Idéal du moi intériorisé, mais une « incarnation » dans la réalité des dieux qui soutient un moi-idéal en conformité avec la divinisation de l’humain que prône le libéralisme postmoderne. La passion mystique de l’adolescent prend donc des nouvelles formes dont témoigne la psychopathologie actuelle de l’adolescence.
Red Narcissus
Authors: Dargent Fanny
Published: January 2013

Résumé La psychothérapie d’une adolescente pratiquant des attaques de corps met en lumière les processus archaïques à l’œuvre en termes de résistance par corps à l’investissement d’objet et refus de l’altérité. La situation duelle réactualise une altérité interne mise à mal par l’aliénation adhésive, antipulsionnelle à des objets tyranniques indifférenciés. La vigilance aux éléments perceptibles, sensori-moteurs, comme effet de l’autre ainsi qu’au contre-transfert travaille, à l’aide d’un style psychodramatique, à résintaurer une transionnalité mise en défaut chez cette adolescente narcissique.
