País Vasco, laboratorio de comunicación alternativa. Compilación de 30 años de experiencias
Authors: Ramírez de la Piscina Martínez Txema 
Published: October 2010

El trabajo resume una investigación sobre comunicación alternativa en Euskal Herria –País Vasco‑ durante los últimos 30 años. Analiza los momentos de flujo y reflujo experimentados en estas tres décadas, deteniéndose en experiencias especialmente significativas. Entre ellas, se cita el caso de la radio HBI Hala Bedi Irratia, una emisora libre de Vitoria-Gasteiz, tolerada pero no legalizada, que en 2008 celebró su 25 aniversario. La emisora tiene millares de oyentes y emite durante las 24 horas del día. Sobrevive gracias al trabajo voluntario de decenas de comunicadores sociales. Nunca han incluido un anuncio pagado en sus ondas, ni han recibido subvenciones del estado. A pesar de ello, el proyecto perdura en la actualidad. La emisora basa su existencia en una amplia red social de cerca de 600 socios y socias y en un uso inteligente de las nuevas tecnologías.
Role of Preimplantation Genetic Diagnosis (PGD) in Current Infertility Practice
Authors: Tempest Helen Ghislaine , Simpson Joe Leigh 
Published: October 2010

ABSTRACTChromosome imbalances are the leading cause of pregnancy loss in humans and play major roles in male and female infertility. Within the past two decades, the development and application of preimplantation genetic diagnosis (PGD) has played an important role in infertility practices worldwide. The purpose of this review is to discuss, how PGD may be applied in combating numerical chromosomal abnormalities and in Robertsonian and reciprocal chromosome translocations. We shall consider prevalence and risk of each aberration, interchromosomal effects and rationale behind use of PGD in each case. Numerical chromosome abnormalities (aneuploidy and polyploidy) in particular affect a very high proportion of preimplantation embryos (~ 50%). Given that a majority of preimplantation embryos are aneuploid, PGD can be used to screen embryos and transfer euploid embryos to improve pregnancy rates and reduce spontaneous abortions. The rationale of utilize PGD to transfer only euploid embryos would seem sound, but controversies exist surrounding application of PGD for aneuploidy detection. To this end, we will discuss the dichotomy between favorable descriptive reports and less favorable randomized clinical trial data. This review will discuss the trend towards differing sources of embryonic DNA (e.g. polar body vs blastomere vs blastocyst) as well as development of novel technologies for 24 chromosomes analysis.
The Role of Gap Junction Proteins in Infertility
Authors: Tripathi Piyush , Tripathi Manorama 
Published: October 2010

ABSTRACTTestis and ovary serve an important role of producing male and female gametes. Their normal functioning is very important for the proper formation of sperm and ovum and thus has a critical role in the successful fertility outcome. Synchronized activity of various cells in the gonads is needed to provide favorable niche for the growth and development of the germ cells. Among various ways of cellular communication, intercellular communication is mediated by gap junctions, which provides open but selective exchange of ion and molecules of restricted size between two adjoining cells. The basic unit of gap junction is connexins. Their important role has been speculated in the maintenance of homeostasis, morphogenesis, cell differentiation, and growth control in higher organisms. The expression of gap junction proteins in reproductive tissues has drawn the attention and interest of researcher to investigate their role in the reproductive outcome. The reports about the correlation of gap junction protein expression pattern in infertility patients and in animal models have suggested their implication in fertility. Some of these gap junction proteins seem to have redundant functions, whereas some could be very critical in the normal fertility and could not be dispensable for the successful outcome of the reproduction.
Role of 3D and 3D Power Doppler to Assess Endometrial Receptivity in IUI Cycles
Authors: Nagori Chaitanya B 
Published: October 2010

ABSTRACTBackgroundThe assessment of the endometrial receptivity at the time of human chorionic gonadotrophin (hCG) is one of the key factors for success of all ART procedures.AimTo assess, if 3D and 3D power Doppler assessment of endometrial receptivity before giving hCG, helps improving pregnancy rates in superovulation with IUI cycles.Settings and DesignA prospective randomized study of 2500 cycles of IUI was done over a period of twelve months for pre-hCG endometrial assessment.MethodEndometrial assessment was done on Voluson 730 Expert, (Wipro GE) using transvaginal multifrequency volume probe 5 to 9 MHz. When follicles and endometrium were considered mature by 2D US and color Doppler, 3D and 3D power Doppler assessment of the endometrium was done before giving hCG. These values were evaluated for conception and nonconception groups.ResultsConception rates were higher, when endometrial volume was between 3 and 7 cc. In our study, we have found endometrial FI > 20 and endometrial VFI > 40 as most optimum.Conclusions3D ultrasound is accurate for volume assessment of endometrium. 3D and 3D PD, when used with 2D US and color Doppler for pre-hCG endometrial assessment, it would definitely improve implantation rates in IUI cycles.
Maternal and Perinatal Outcome in Pregnancies Following Infertility
Authors: Thyagarajan Chitra , Dasari Papa 
Published: October 2010

ABSTRACTContextGeneral practitioners as well as obstetricians are coming across a large number of pregnant women whose conceptions are following a period of infertility or treatment for the same. There is a controversy in the literature regarding the occurrence of adverse outcomes of pregnancy in such women.AimsTo assess the maternal and perinatal outcome in pregnancies that occurred after a period of infertility and to compare the outcome in spontaneous conceptions with the conceptions following treatment for infertilitySettings and DesignRetrospective analysis of hospital records of 200 pregnancies following infertility during the year 2009 in a tertiary care center in South India.Material and MethodsAll the women were divided into two groups,viz: Group 1—those who had history of infertility but conceived spontaneously and Group 2—those with history of infertility and conceived only after treatment for infertility. The main outcome measures were antenatal complications and adverse neonatal complications.Statistical analysisThe statistical package SSPS version 15.0. Chi-square and student ‘t’ test was used for nonparametric and parametric variables.ResultsThe incidence of hypertension was 60% and that of gestational diabetes was 7%. Obstetric complications included increased incidence of preterm labor (23.5%) and premature rupture of membranes (38%). There was no statistically significant difference in both groups though the medical complications especially hypertension was high in the pregnancies following spontaneous conceptions, i.e. untreated group. There was a greater demand for the NICU care mainly because of prematurity. The PNMR was (40/1000) less than the institutional rate of 72/1000 births.ConclusionsThere is increased incidence of hypertension premature rupture of membranes and preterm delivery in pregnancies following infertility. There is no significant statistical difference in the adverse pregnancy outcomes between spontaneous conception and those treated for infertility.Key MessagesPregnancies following infertility are at increased risk of developing hypertension and preterm labor and hence these women should be screened for the same and preventive measures to be undertaken to achieve good maternal and perinatal outcome.
Obesity in Gestational Diabetes: Emerging Twin Challenge for Perinatal Care in India
Authors: Fernandez Evita , Surapaneni Tarakeswari 
Published: October 2010

ABSTRACT
The current study aimed to determine the prevalence of obesity and gestational diabetes (GDM) and the association of obesity and gestational diabetes with adverse pregnancy outcomes in a population of pregnant women. Routine antenatal care included the estimation of body mass indices, assessment of blood glucose levels, including glucose challenge tests and oral glucose tolerance test, fetal growth monitoring and nutritional counseling. The prevalence of GDM and obesity in this population was 8.43% (95% CI: 7.47-9.40) and 19.49% (95% CI: 18.12-20.87) respectively. The prevalence of obesity increased to 54.63% (95% CI: 52.91-56.36), if we used the ICMR guidelines for BMI in this population. Cesarean sections (adjusted OR: 2.04, 95% CI: 1.43-2.89), large for gestational age (LGA) babies (adjusted OR: 3.82, 95% CI: 2.11-6.92) and macrosomia (adjusted OR: 20.90, 95% CI: 3.29-132.77) was associated with obesity in GDM (based on the ICMR guidelines for BMI). Results from this study indicate that gestational diabetes and obesity are increasingly important priorities for perinatal care in India.

ABSTRACTA 25 years old woman with Down syndrome (DS) presented at 9 weeks gestational age. She belonged to a very supportive family. She was married to a person with normal karyotype and conceived within 3 months of marriage. Her antenatal period was uneventful, except for mild IUGR and oligohydroamnios 32 weeks onwards. At 38 weeks, she underwent induction of labor. She tolerated labor pains well but because of failure to progress, cesarean section was performed. She delivered a 2 kg male baby, who was phenotypically and genotypically normal. Screening for trisomy 21 should be offered to all women as part of routine antenatal care. This offer should include detailed counseling about the implications and limitations of the test used in the screening program. The available second trimester screening tests are the double, triple and quadruple tests. Children with Down syndrome may benefit from speech therapy, physical therapy and occupational therapy. They may receive special education and assistance in school. Full potential of Down patients can be utilized only with complete support of family and society.
Thioamide Compounds as Corrosion Inhibitors for Stainless Steel in H2SO4 Solution
Authors: Hosseini S. M. A. , Salari M. , Motlagh M. Ghanei 
Published: October 2010

Abstract
The influence of organic compounds on the corrosion of stainless steel in 0.5 M sulfuric acid (H2SO4) was investigated using weight-loss and potentiodynamic polarization techniques, as well as open-cirucuit potential (OCP) measurements. The nature of the film formed and the adsorption mechanism, as well as thermochemical parameters involved, were explored and expounded. This investigation indicated that the inhibition efficiency increases with increasing the concentration of organic compounds. The inhibitors are of the mixed type but dominantly act as anodic in 0.5 M H2SO4. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used to characterize the surface and examine the morphology of the Type 304 (UNS S30400) stainless steel under ordinary acid attack with that formed under inhibited conditions. The adsorption of the inhibitors was expressed reasonably by the Langmuir adsorption isotherm. The calculated activation energy and thermodynamic parameters point to a mixed adsorption pattern of inhibitor molecules, with physical adsorption as the dominant mode.
Cyclic Voltammetric Studies on Selected Tin-Silver Binary Alloys in Sodium Hydroxide Solution
Authors: Ghoneim A. A. , Ameer M. A. , Fekry A. M. , Heakal F. El-Taib 
Published: October 2010

Abstract
The electrochemical corrosion and passivation behavior of four selected tin-silver alloys, xSn-Ag (x = 26, 50, 70, and 96.5 wt%) (II through V), in addition to their pure metallic components, Ag(I) and Sn(VI), were investigated in aqueous sodium hydroxide (NaOH) solution. The techniques used are linear sweep cyclic voltammetry and electrochemical impedance spectroscopy (EIS). In general, for all studied samples, the cyclic voltammograms show that increasing the scan rate shifts the passivation peak potential (Ep,a) positively and the reduction peak potential (Ep,c) negatively with a concomitant increase in both the passivation peak current density (ip,a) and the reduction peak current density (ip,c). EIS results investigate that the total resistance (RT) and the relative thickness (1/C) of the passive layers on the six tested electrodes are both found to increase with time of immersion, being more pronounced for sample II. Although this silver-rich alloy (74 wt%) has the most protectiveness among the tested specimens, the relative thickness of its passive film is much lower than that for the pure silver. After any immersion period the passivation sequence of the six samples can be arranged in the following order:II ≫ I &gt; IV &gt; III &gt; V &gt; VI.
Solving the Paradox of Monetary Profits
Authors: Keen Steve 
Published: October 2010

AbstractBruun and Heyn-Johnsen (2009) state the paradox that economics has failed to provide a satisfactory explanation of how monetary profits are generated, even though the generation of a physical surplus is an established aspect of non-neoclassical economics. They emphasise that our ability to explain phenomena like the Global Financial Crisis (GFC) will be limited while ever we are still unable to explain this fundamental aspect of capitalism. In fact this paradox can be solved very simply, using insights from what is known as “Circuit Theory”. In this paper the author shows how monetary profits are generated, and uses a monetary circuit of production model to derive policy conclusions about how to overcome a “credit crunch” that reverse the guidance given by the standard but empirically falsified “money multiplier” model of credit money creation.
An Enabling Mechanism for the Creation, Adjustment, and Dissolution of States and Governmental Units
Authors: Hausken Kjell , Knutsen John F. 
Published: October 2010

Abstract
The article proposes an enabling mechanism for the creation, adjustment and dissolution of governmental units, giving autonomy to each individual as in a direct democracy. The mechanism is designed such that Pareto optimality is possible, in contrast to earlier models which make various assumptions such as majority voting. Individuals are taken seriously acknowledging that they are best equipped to find their own solutions. The emphasis is on the practical approach of how individuals discover and implement their subjective preferences and how this discovery and implementation process can be facilitated and corresponding costs lowered. Governmental units are subjected to some of the same market forces as business firms. This brings the interaction between governmental units closer to a market structure, and serves to eliminate or reduce many of the coercive elements of government.
Extended fuzzy function model with stable learning methods for online system identification
Authors: Beyhan Selami , Alci Musa 
Published: October 2010

AbstractThe aim of the online nonlinear system identification is the accurate modeling of the current local input‐output behavior of the plant without using any prior knowledge and offline modeling phase. It is a challenging task for many intelligent systems when used for real‐time control applications. In this paper, we propose a novel computationally efficient extended fuzzy functions (EFF) model for system identification of unknown nonlinear discrete‐time systems. The main contributions are to introduce an effective quasi‐nonlinear model (EFF) and propose adaptive learning rates (ALR) for recursive least squares (RLS) and gradient‐descent (GD) methods. The asymptotic convergence of the modeling errors and boundedness of the parameters are proved by using the input‐to‐state stability (ISS) approach. Numerical simulations are performed for Box–Jenkins gas furnace system and a nonlinear dynamic system. The benefits of its accuracy, stability and simple implementation in practice indicate that EFF model is a promising technique for online identification of nonlinear systems.

Principles of Branching Morphology and Anatomy in Arborescent Monocotyledons and Columnar Cacti as Concept Generators for Branched Fiber‐Reinforced Composites
Authors: Schwager Hannes , Haushahn Tobias , Neinhuis Christoph , Speck Thomas , Masselter Tom 
Published: October 2010

AbstractThe branching of arborescent (tree‐like) monocotyledonous plants of the genus Dracaena or of columnar cacti differ considerably from that observed in other dicotyledonous or gymnosperm trees. The investigated ramifications exhibit distinctive morphological and anatomical features. In arborescent monocotyledons the side branches are attached to the main stem by a fiber‐reinforced tissue newly formed during secondary growth, clasping the main stem and finally resulting in a “flange‐mounted” structure. In the case of columnar cacti the most obvious feature is the pronounced constriction at the attachment point of the branches that is also mirrored in the lignified vascular tissue. One might argue that these characteristic morphological and anatomical features in regions exposed to high mechanical stresses represent structural weaknesses. However, the outer shape and the inner structures of the ramifications cause considerable stability and structural integrity of the stem‐branch connection under static and dynamic loading. Our results allow concluding that load‐adaptation in ramified plant structures is a result of a combination of optimization in outer shape and fiber arrangement within the ramifications. Numerical methods simulating the mechanical behavior based on data obtained from the studied plants support this assumption. A deeper understanding of the outer shape of the connection between shoot and branch as well as of the arrangement of the lignified vascular tissues in the branching region, may contribute toward alternative concepts for branched technical light‐weight‐structures. In particular for braided fiber‐reinforced composites this biomimetic approach might help to keep the demand on the available design space as small as possible.
Incidental capture of Caretta caretta in trammel nets off the western coast of Sardinia (Italy): statistical models of capture abundance and immediate survival
Authors: Cambiè Giulia 
Published: October 2010

Abstract
Trammel nets are one important cause of sea turtle mortality resulting from incidental capture. This study presents findings over a 10‐year period during which loggerhead turtle by‐catch in trammel nets, set off the central west coast of Sardinia (Italy) in the summer months, was recorded by 17 fishing vessels.
Since the by‐catch registered represented counts of a rare event, data from the 17 vessels were used in the zero‐inflated Poisson (ZIP) model to determine the abundance of turtle by‐catch in trammel nets of the entire fleet, while a binomial generalized linear model was used to assess the probability of immediate survival for sea turtles incidentally caught in this gear.
The ZIP model quantified in about 45% the probability that 0.6 turtles have been caught by each vessel using trammel nets during summer over the 10‐year period. In addition, the model estimated a total of 916 by‐catch if the entire small‐scale fleet was to use trammel nets in the study area in the summers between 1992 and 2001, with a direct mortality rate of 69%.
The probability of immediate survival for sea turtles caught in trammel nets seems to be directly related to the size of the specimens caught; however, this relationship is plausible only when incidental capture in the net occurs shortly before gear retrieval.
The study area represents a region where the abundance of sea turtle by‐catch per vessel in trammel nets was much higher in July and August than in June and could represent a potential hot spot for the presence of juvenile loggerhead turtles, with high levels of interactions between the species and this fishing gear. Further research should better characterize the incidents of by‐catch and assess potential innovative solutions that allow small‐scale fisheries to coexist alongside sea turtles.
