La presente investigación se realizó con los objetivo de determinar las principales causas que obstaculizan la agilización del proceso de adopción en el Ministerio de la Familia, en Managua.
Se conoce que la principal obstaculización del proceso de adopción incide en la vía administrativa y se describe como larga y tardía, provocando en las parejas que quieren adoptar desistir de la idea, ya que les resulta agotador, al
igual se pierde la oportunidad de brindar una familia a un menor, vulnerando su derecho, y por ello se ha planteado como interrogante ante este problema, ¿Cuáles son las principales causas en la práctica que obstaculizan la
agilización del proceso de adoptar en parejas que asisten al Ministerio de la Familia durante el periodo 2005-2010?
Se ha estructurado el presente trabajo en cuatro capítulos:
Capítulo I: Generalidades sobre el proceso de Adopción
Capítulo II: Procedimiento Administrativo de la Adopción
Capítulo III: Comparación del proceso de Adopción dispuesto en el proyecto Código de Familia con el procedimiento vigente Capítulo IV: Causas que dificultan la agilización del Proceso Administrativo de Adopción a través del Estudio de Casos.
La presente investigación es de tipo cualitativa descriptiva ya que se pretende describir las causas que obstaculizan el procedimiento administrativo de
la adopción partir de la ley vigente y del estudio de casos para contrastarlos. Su diseño no incluye hipótesis sino la realización de preguntas directrices las cuales
se utilizaron como base del desarrollo de la investigación. Se utilizó como técnica de recopilación de información la revisión documental, así como la realización de
entrevistas a los encargados en el área administrativa del Ministerio de la Familia,como máxima autoridad en el proceso administrativo de adopción y finalmente la Principales causas que obstaculizan la agilización del proceso de adopción en el Ministerio de la Familia, en el año 2005-2010 en Managua” 8 revisión de expedientes que permitió determinar las causas que impiden que los procesos sean ágiles y expeditos

A compact model of the ZARC for circuit simulators in the frequency and time domains
Equivalent-circuit models containing fractional-order elements are often employed to make use of fractionalorder
calculus in the frequency and time domains in a variety of applications. Many of these circuits contain
constant-phase elements that appear in parallel with a resistor in a configuration called ZARC. But to avoid
fractional order derivatives and include it in circuit simulators, the ZARC itself can also be replaced by
equivalent circuit models that only contain integer order elements, such as resistors and capacitors. In this
article, a novel compact model is presented to substitute the ZARC by a multiple-RC network. This model is
valid for a continuous value of the order exponent and is applicable over a very wide range of frequencies,
making it useful in both the frequency and time domains. Since it uses only basic functions and operators, it
has been easily implemented as a subcircuit in circuit simulators. The validity of the model has been verified
and it has been compared with some previously proposed passive circuit models. The model has also been
discussed in relation to the initialization problem, which is an often overlooked challenge in fractional-order
circuits.Universidad de Granada/CBU
Reproductive Potential and Outcomes in Patients with Hidradenitis Suppurativa: Clinical Profile and Therapeutic Implications
We would like to thank Charlotte Bower for improving the English of this
manuscript.There are scarce data available regarding the impact of hidradenitis suppurativa (HS) on fertility, course and outcome of pregnancy and risk associated with treatments. The aims of this study are (1) to describe the clinical profile of HS women of childbearing age with and without accomplished reproductive desires and (2) to describe the prescribed treatments based on the fulfillment of reproductive intentions. We conducted a prospective observational study that included 104 HS women of childbearing age, 50.96% (53/104) with unfulfilled reproductive desires. These women were younger (29.08 vs. 42.06 years, p < 0.001), less frequently married and higher educated than women with fulfilled reproductive desires. Their age of disease onset was lower, but disease duration was shorter, in concordance with a lower International Hidradenitis Suppurativa Severity Score System (IHS4) and lower number of draining tunnels. Combined oral contraceptives were more frequently prescribed in women with unfulfilled reproductive desires (30.19% vs. 9.80%, p = 0.013) while biologics were less used in this group (3.77% vs. 13.73%, p = 0.08). In conclusion, a higher educational level and an earlier disease onset, with potential implications in finding a partner, may make the fulfillment of reproductive desires difficult for patients with HS. This study could help clinicians to achieve a better understanding of the specific characteristics of HS during childbearing age and consider reproductive desires when making treatment decisions
High Angular Resolution Radio Observations of the HL/XZ Tau Region: Mapping the 50 AU Protoplanetary Disk around HL Tau and Resolving XZ Tau S into a 13 AU Binary
We present new 7 mm and archive 1.3 cm high angular resolution observations
of the HL/XZ Tau region made with the VLA. At 7 mm, the emission from HL Tau
seems to be arising in a clumpy disk with radius of order 25 AU. The 1.3 cm
emission from XZ Tau shows the emission from a binary system with 0"3 (42 AU)
separation, known from previous optical/IR observations. However, at 7 mm, the
southern radio component resolves into a binary with 0"09 (13 AU) separation,
suggesting that XZ Tau is actually a triple star system. We suggest that the
remarkable ejection of gas from the XZ Tau system observed with the HST may be
related to a periastron passage of this newly discovered close binary system.Comment: Accepted by The Astrophysical Journal Letters (23 Jan 2009
Synthesis, characterization, bioactivity and biocompatibility of nanostructured materials based on the wollastonite-poly(ethylmethacrylate-co-vinylpyrrolidone) system
Composite materials are very promising biomaterials
for hard tissue augmentation. The approach assayed
in this work involves the manufacturing of a composite
made of a bioactive ceramic, natural wollastonite (W) and a
nanostructured copolymer of ethylmethacrylate (EMA) and
vinylpyrrolidone (VP) to yield a bioresorbable and biocompatible
VP–EMA copolymer. A bulk polymerization was
induced thermally at 508C, using 1 wt % azobis(isobutyronitrile)
(AIBN) as free-radical initiator. Structural characterization,
compressive strength, flexural strength (FS), degradation,
bioactivity, and biocompatibility were evaluated in
specimens with a 60/40 VP/EMA ratio and ceramic content
in the range 0–60%. A good integration between phases
was achieved. Greater compression and FS, in comparison
with the pure copolymer specimens was obtained only
when the ceramic load got up to 60% of the total weight.
The soaking in NaCl solution resulted in the initial swelling
of the specimens tested. The maximum swelling was
reached after 2–3 h of immersion and it was significantly
greater for lower ceramic loads. This result makes the polymer
component the main responsible for the interactions
with the media. After soaking in SBF, microdomains segregation
can be observed in the polymer component that can
be related with a dramatic difference in the reactivity of
both monomers in free radical polymerization, whereas the
formation of an apatite-like layer on the W surfaces can be
observed. Biocompatibility in vitro studies showed the absence
of cytotoxicity of all formulations. The cells were able
to adhere on the polystyrene negative control and on specimens
containing 60 wt % wollastonite forming a monolayer
and showing a normal morphology. However, a low cellular
growth was observed. 2008 Wiley Periodicals, Inc.

Conventional and Molecular Diagnosis of Drug-Sensitive and Drug-Resistant Pulmonary Tuberculosis
Tuberculosis is a transmissible disease, which is primarily caused by the bacteria Mycobacterium tuberculosis and by other Mycobacterium species, forming the Mycobacterium tuberculosis complex. Until the end of the 20th Century, most cases of pulmonary tuberculosis were considered curable. Nevertheless, the rising of tuberculosis resistant to first- and second-line anti-tuberculous drugs is threatening the world’s tuberculosis control programs. Due to this fact, the World Health Organization and other public health institutions recommended applying the conventional methods, affordable by low-incoming countries, to diagnose tuberculosis and to develop faster and more sensitive and specific methods to identify M. tuberculosis and determine their condition of anti-tuberculous drug resistance or drug sensitivity. In this chapter, we mention the most used conventional and molecular methods designed to identify M. tuberculosis and to determine their drug sensitivity or drug resistance. We also briefly describe the fundamentals of methods and its advantages and limitations
