Chiapas representó en el siglo XVII una región donde confluían los mitos, temores y fascinaciones de colonos y europeos. Al ser visitada por Thomas Gage en su travesía hacia Guatemala, es descrita en su Nuevo reconocimiento de las Indias Occidentales de modo muy distinto cuando el narrador, como es este caso, registra sus vivencias personales e, incluso, pasionales. Sólo la historiografía moderna podría explicarnos particulares pasajes en que el viajero es abordado súbitamente por una realidad que pasa desapercibida a otros viajeros con un programa muy claro de supervisión y registro de datos, como es el caso de Antonio Vázquez de Espinosa en su Descripción de la Nueva España. Si el historiógrafo describe puntualmente flora, fauna y geografía, el narrador huele, paladea y recorre con nosotros el laberinto de la tierra chiapaneca. El paisaje a través de la persona, con todos los cabos sueltos y apariciones inexplicables para quien se interna en lo desconocido, cobran, a la luz de investigaciones recientes acerca del contexto sociohistórico de Chiapas, un sentido cabal que no sólo nos ilustra, sino que nos interna y se nos interna.

This paper describes the development of a semiconductor strain gage tactile transducer. It was designed with the goal of measuring finger forces without affecting the hand dexterity. The transducer structure was manufactured with stainless steel and has small dimensions ( 4 min diameter and I min thickness). It is light and suitable to connect to the finger pads. It has a device that prevents its damage when forces are applied. The semiconductor strain gage was used over due its small size and high sensitivity, although it has high temperature sensitivity. Theory, design and construction details are presented the signal conditioning circuit is very simple because the semiconductor strain gage sensitivity is high. It presents linear response from 0 to 100 N, 0.5 N resolution, fall time of 7.2 ms, good repeatability, and small hysteresis. The semiconductor strain gage transducer has characteristics that can make it very useful in Rehabilitation Engineering, Robotics, and Medicine.

This paper describes a high senstivity low cost capacitive strain gage sensor. The theory, design, and sensor construction details are presented. It consists of eight capacitive sensors connected in two full bridges. The capacitive strain gage sensor structure was designed in order to produce high sensitivity and low dependence with temperature. By using a simple signal conditioning circuit constituted by a differential amplifier, a band-pass filter, and a precision rectifier the device can measure forces with resolution of 0.009 N and precision of 98.7%. It is rugged, presents linear response, and good repeatability. It presents sensitivity of 8.7 V/N and fall time of 12 ms.

We have used a combination of computerized database mining and experimental expression analyses to identify a gene that is preferentially expressed in normal male and female reproductive tissues, prostate, testis, fallopian tube, uterus, and placenta, as well as in prostate cancer, testicular cancer, and uterine cancer. This gene is located on the human X chromosome, and it is homologous to a family of genes encoding GAGE-like proteins. GAGE proteins are expressed in a variety of tumors and in testis. We designate the novel gene PAGE-1 because the expression pattern in the Cancer Genome Anatomy Project libraries indicates that it is predominantly expressed in normal and neoplastic prostate. Further database analysis indicates the presence of other genes with high homology to PAGE-1, which were found in cDNA libraries derived from testis, pooled libraries (with testis), and in a germ cell tumor library. The expression of PAGE-1 in normal and malignant prostate, testicular, and uterine tissues makes it a possible target for the diagnosis and possibly for the vaccine-based therapy of neoplasms of prostate, testis, and uterus.
