Skin 3D Bioprinting. Applications in Cosmetology  [PDF]
Cristina Velasquillo, Eduardo A. Galue, Lourdes Rodriquez, Clemente Ibarra, L. Guillermo Ibarra-Ibarra
Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2013, DOI: 10.4236/jcdsa.2013.31A012
Abstract: Tissue engineering has been used for the treatment of several skin diseases and lesions; however, tissue engineering and regenerative medicine also have a huge potential in cosmetology. They include skin substitutes, cell therapy and wound-healing treatments based on biomaterial-based replacements and 3D systems. This review focuses on the bioprinting technology and how it can improve skin functions, restoring pigmentation or helping hair follicles to develop.

Self-regulation as a regulatory strategy: The Italian legal framework
Simona Rodriquez
Utrecht Law Review , 2007,
Abstract: This article aims to provide an overview of the evolution of self-regulatory mechanisms in Italy. A brief overview of the Italian system of sources of law has showed that the model of the sources of law rooted in the Italian constitution is typically positivistic and centred on the pivotal role of Parliament, the only body empowered to legislate, either directly or by delegating its normative powers to the Government, within expressly specified limits. What room, if any, is there for self-regulatory rules? If one of the most interesting aims of the research was to analyse to what extent the self-regulatory phenomenon is compatible with Parliament’s undisputed sovereignty and with the linked principle of the rule of law, it should be clear that rules made by private actors (i.e. self-regulatory rules), which pretend to have external effects (binding erga omnes), can be considered as law and, as such, as sources of law, as long as they can be ‘incorporated’ into and recognized in some of the formal sources of Italian law. This seems the only possible and constitutionally compatible interpretation of a phenomenon (self-regulation) which, instead, could potentially be able to place the formal hierarchy of sources of law in jeopardy. On the other hand, the results of the study make clear that, even when Parliament confers its normative powers on any other bodies (i.e. either independent administrative authorities or professional orders, or, more in general, any self-regulatory associations), it is unlikely that it will give up determining the limits within which those normative powers have to be exercised. Some authors actually consider this sort of ‘delegated legislation’ to be a means for the State to reassert its sovereignty. Anyway, this new pluralistic ‘architecture’ will undoubtedly allow the legislator to retain some exclusive duties: first and foremost, the power to prescribe the institutional conditions which underlie the basis of ‘private self-regulatory governance’, as well as the aims of their future normative action; secondly, to intervene in order to correct, if necessary, the new consensual rules.
Conditional Aharonov-Bohm Phases with Double Quantum Dots
Roberta Rodriquez,Jiannis K. Pachos
Physics , 2004,
Abstract: A quantum dot proposal for the implementation of topological quantum computation is presented. The coupling of the electron charge to an external magnetic field via the Aharonov-Bohm effect, combined with the control dynamics of a double dot, results in a two-qubit control phase gate. The physical mechanisms of the system are analysed in detail and the conditions for performing quantum computation resilient to control errors are outlined and found to be realisable with present technology.
2-Octyl Cyanoacrylate Skin Adhesive for Topical Skin Incision Closure in Female Pelvic Surgery  [PDF]
Rebecca L. James, Marilyn Alejandro-Rodriquez, Elba Adriana Perez, Jeffrey Mangel
Open Journal of Obstetrics and Gynecology (OJOG) , 2015, DOI: 10.4236/ojog.2015.55041
Abstract: Background: 2-octyl cyanoacrylate (2OCA) high viscosity tissue adhesive (Medline Industries, Inc., Mundelein, IL) is a liquid topical skin adhesive. 2OCA offers the same design features and clinical utility in terms of flexibility, strength, and low complication rate as the commercially available 2OCA tissue adhesives. Additionally, 2OCA features high viscosity allowing for better control during the application process, polymerization without the use of an external activator, and a distinctive violet color for ease of application visualization. Objective: The aim of this prospective case series is to descriptively report clinical data with the application of 2OCA as a topical incision closure system in female pelvic surgery. The primary outcomes included: incisional pain, incisional dehiscence, and post-operative bleeding. The secondary outcome included drying times of the adhesive with regard to incision length. Methods: A prospective open-label observational case series study was conducted to evaluate the use of 2OCA in surgical wound closure of the topical skin in adult patients undergoing gynecologic surgical procedures. A total of 50 adult women undergoing gynecologic surgery were enrolled. 2OCA was applied only by surgeons who had undergone product training to the incisions in a standardized, protocol-defined fashion. Drying times for the adhesive and photography were recorded intraoperatively. Post treatment follow-up was conducted with queries of pain level, incisional dehiscence, and incisional bleeding immediately post-operatively, 48 hours, 5 - 10 days and 14 days post-treatment. Adverse events were documented. Results: 2OCA was applied to a total of 154 incisions from the 50 patients enrolled to the study. The procedures included: 16 laparoscopic total hysterectomies, 4 diagnostic laparoscopies, 2 laparoscopic myomectomies, 2 laparoscopic bilateral or unilateral salpingo-oophorectomies, 5 total robotic-assisted laparoscopic surgeries (2 total hysterectomies, 1 supracervical hysterectomy, 1 sacrocolpopexy, and one excision of endometriosis), 7 sacral neuromodulation procedures, and 18 midurethral slings. The overall rate of incisional dehiscence was 3% (4/154). The rate of reported incisional bleeding was 3% (4/154). There was 1 incisional infection. The pain reports based on a 10-point scale had a mean of 4.96 immediately post-operatively, which decreased to a mean score < 1 (0.2) by post-op day (POD) 14. The mean drying times for the various lengths of incisions included the following: 1.28 minutes for incisions ≤ 5 mm, 1.53 minutes for

Lourdes Ruiz
Journal of Building Construction and Planning Research (JBCPR) , 2015, DOI: 10.4236/jbcpr.2015.34016
Abstract: This research aims to propose environmental prevention and mitigation on fragile coastal ecosystems due to the actions of the tourist architecture, using methods of life-cycle assessment of buildings, matrix methods of the actions that cause severe environmental impact and statistical processing through multivariate analysis. A study of projects was undertaken in Cayo Coco located to the north of Ciego de Avila, Cuba, being built today and where the tourist development of the archipelago Sabana-Camaguey started. It has been determined that suitable architecture would decrease the negative impact of these fragile ecosystems.

Lourdes Ruiz
Journal of Building Construction and Planning Research (JBCPR) , 2016, DOI: 10.4236/jbcpr.2016.41005
Abstract: The aim of this study is to apply the methodology for assessment of environmental impact whether of a physicochemical nature and on the biodiversity and ecosystems, or whether sociocultural and economic aspects of the historic towns with tourism interest that are assessed. The automated method of the RIAM software is used which requires a baseline study of the environment of different towns to be prepared. In addition, the analysis of the social perception on tourism of the local people from the course work of students at the UIDE shall be applied. The conclusions of the case studies undertaken allow for strategic proposals and recommendations to be prepared so that they can be incorporated into the management plans for tourism in the historic towns with heritage value.
Incorporation of Environmental and Sustainable Indicators in Universities  [PDF]
Lourdes Ruiz
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.76075
Abstract:

The use of environmental and sustainable indicators of global organizations has greater advantages than those of national initiatives or those developed by researchers in said subject, due to the fact that they have a much broader scope for sustainability, have been applied in a systematic manner and therefore have greater comparability and reliability. The environmental indicators are constructed from the approaches to sustainable development in universities with regards to the social, economic, institutional and environmental dimensions in the organizations. This work involves the application of environmental and sustainable indicators for internationally recognized efficiency in university activities, which contribute towards organizing, summarizing and developing the processes for development planning and environmental management.

Adverse Environmental Effects of Tourism on Communities in the Ecuadorian Highlands Region  [PDF]
Lourdes Ruiz
Current Urban Studies (CUS) , 2017, DOI: 10.4236/cus.2017.53019
Abstract: The objective of this study is to determine the adverse environmental effects of tourism activities on various heritage populations located in the sierra or Andean highlands region of Ecuador. The effects being studied have been classified into impacts on the physical, abiotic, biotic, socio-culture and economic environment. The automated method using RIAM (Rapid Impact Assessment Matrix) software was employed in this analysis, which required the preparation of a baseline study in the small communities evaluated. A social perception survey was conducted of local residents regarding tourism, assisted by International University of Ecuador students fulfilling practical coursework requirements. Based on the conclusions of the case studies, some strategic proposals and recommendations were developed that can be incorporated into sustainable tourism management plans in communities with natural and cultural heritage values.

A note on the partition dimension of Cartesian product graphs
Ismael G. Yero,Juan A. Rodriquez-Velazquez
Mathematics , 2010, DOI: 10.1016/j.amc.2010.08.038
Abstract: Let $G=(V,E)$ be a connected graph. The distance between two vertices $u,v\in V$, denoted by $d(u, v)$, is the length of a shortest $u-v$ path in $G$. The distance between a vertex $v\in V$ and a subset $P\subset V$ is defined as $min\{d(v, x): x \in P\}$, and it is denoted by $d(v, P)$. An ordered partition $\{P_1,P_2, ...,P_t\}$ of vertices of a graph $G$, is a \emph{resolving partition}of $G$, if all the distance vectors $(d(v,P_1),d(v,P_2),...,d(v,P_t))$ are different. The \emph{partition dimension} of $G$, denoted by $pd(G)$, is the minimum number of sets in any resolving partition of $G$. In this article we study the partition dimension of Cartesian product graphs. More precisely, we show that for all pairs of connected graphs $G, H$, $pd(G\times H)\le pd(G)+pd(H)$ and $pd(G\times H)\le pd(G)+dim(H).$ Consequently, we show that $pd(G\times H)\le dim(G)+dim(H)+1.$
