A propósito de su publicaciIn this article we publish two new amulets of bes found near the sanctuary of our lady of regla in chipiona and in the archaeological site of viña de las cántaras at rota, both of them in the province of cadiz. About its publication we propose a biologic

Effect of climate and insemination technique on reproductive performance of gilts and sows in a subtropical zone of Mexico

The objective of this study was to analyse the reproductive performance of hybrid (Yorkshire x Landrace) gilts/sows in relation to temperature-humidity index (THI) at artificial insemination (AI), season of AI, occurrence of estrus >8 d post-weaning, repeated estrus, insemination technique (cervical, CAI or post-cervical, PCAI) and parity. Data included 8851 reproductive records (1771 for gilts and 7080 for sows) from a pig farm in a sub-tropical zone (THI ranged from 72.9 in January to 81.8 in June). A decrease in pregnancy rate (PR, 89.8 vs 93.0%; P<0.01) and a tendency to decline farrowing rate (FR, 87.9 vs 90.3%; P=0.07) following AI during high THI (>82), compared to AI at <74 THI were observed. The spring and summer season were associated with decreased (P<0.01) PR compared with fall and winter (90.0% vs 93.0%). Likewise, FR decreased in spring and summer compared to fall and winter (88.5% vs. 90.9%). FR was higher (P<0.01) in non-repeat breeders compared with that of repeat-breeders (90.3% vs 76.2%). Litter size increased (P<0.01) from 10.8 ± 3.2 to 11.1 ± 3.1 pigs when the interval from weaning to estrus was >8 d. The insemination technique did not affect PR and FR but the litter size decreased (P<0.05) from 11.3 ± 3.0 to 11.1 ± 2.9 pigs when PCAI was used compared to CAI. This study reaffirms the negative effects of the hot season on reproductive performance of gilts/sows, although thermal stress at AI did not cause foetal losses. Also, there is no advantage in using the PCAI as compared to the CAI in gilts/sows with high numbers of sperm cells per AI

¿Los Millennials Saltillenses Son Innovadores Como Consumidores de Ropa?

The objective of this research work is to analyze the behavior of young people belonging to generation Y known as millennials, regarding the purchase of clothing. According to Kotler and Keller (2012), a generation is a group of persons whose ages are similar and who lived in the same era. This study is considered as a descriptive and exploratory investigation. It is based on a sample of 261 persons from 21 to 36 years of age in the city of Saltillo, Coahuila. A questionnaire was applied with the scale 'Type of consumers of clothes of Chengedzai' according to the study of Manillall and Lawrence (2014). Using Pearson's chi square and an answer percentage comparison with the IBM SPSS software, the findings suggest that with regard to the innovative factor, the interviewees do not consider themselves as an innovative buyer when they buy clothes. This is because the answers concerning the variables that suggest this have a low score

LOS PAISAJES HISTÓRICOS DEL VALLE DEL GUADIAMAR (SEVILLA): LA MINERÍA Y LA METALURGIA EN EL EXTREMO ORIENTAL DEL CINTURÓN IBÉRICO DE PIRITAS

The f irst results of the research project Los Paisajes del Guadiamar are presented in this paper, paying special attention to archaeometallurgical aspects. This project has been going on since 2010, located in the mid-valley  of the River Guadiamar  (central-western  area of the province of  Seville)  and  backed  by  the  “Fundación  Focus-Abengoa”.  Although  not  all  the  archaeo- logical  and  analytical  data  are  yet  available,  a preliminary  approach  permits  to put  forward some conclusions and, above all, to validate or to refute hypotheses and theories proposed in previous research works.En este artículo se presentan los primeros resultados, incidiendo especialmente  en los aspectos arqueometalúrgicos, del proyecto de investigación Los Paisajes del Guadiamar. Este proyecto se desarrolla  desde  el año 2010,  f inanciado  por la “Fundación  Focus-Abengoa”,  en el valle medio del río Guadiamar (centro-oeste  de la provincia  de Sevilla).  Aunque aún no se ha con- cluido la obtención de todos los datos arqueológicos y analíticos, una valoración preliminar permite adelantar algunas conclusiones  y, sobre todo, contrastar hipótesis y teorías enunciadas en anteriores trabajos de investigación

Anisotropic phase-map denoising using a regularized cost-function with complex-valued Markov-random-fields

In our recently reported work [1] (Villa et al., 2009) we derived a regularized quadratic-cost function, which includes fringe orientation information, for denosing fringe pattern images. In this work we adopt such idea for denoising wrapped phase-maps. We use a regularized cost-function that uses complex-valued Markov random fields (CMRFs) with orientation information of the filtering direction along isophase lines. The advantage of using an anisotropic filter along isophase lines is that phase and noise can be properly separated while 2 pi phase jumps are preserved even in high frequency zones. Apart from its robustness, the outstanding advantage of our method is its minimal computational effort. We present some results processing simulated and real phase-maps

Protohistoric mining in the Extremadura: The case of in the Cerro de San Cristóbal de Logrosán (Cáceres)

Este artículo resume los trabajos realizados en el Cerro de San Cristóbal (Logrosán, Cáceres) entre  1998  y 2002.  Dichos  trabajos,  impulsados  por  el Dr.  Craig  Merideth  hasta  su muerte en 2005,  permitieron  reconocer  un asentamiento  minero-metalúrgico especializado  en el be- nef icio de la casiterita. Pese a estar muy alterado por las explotaciones de los años cincuenta del siglo XX, se pudieron  documentar  restos de cabañas,  trazas de labores  antiguas  y ciertos aspectos de la “cadena operativa” de la explotación y uso del estaño en este enclave. Todo ello  se enmarca  en un contexto  crono-cultural  de los  siglos  IX/VIII-VII/VI  a.C.,  durante  el cual el actual territorio extremeño se conformó como periferia tartésica. Por otra parte, se avanzan los resultados metalúrgicos preliminares de las nuevas actuaciones llevadas a cabo en 2013 en el Cerro de San Cristóbal  tras su declaración  como “geositio”  dentro del Geoparque “Villuercas-Ibores-Jara”.In this paper the archaeological work carried out in Cerro de San Cristóbal (Logrosán, Cáceres) during the period 1998 to 2002 is summarized. The work, led by Dr. Craig Merideth until his  death  in 2005, allowed  to document  what was interpreted  as a mining-metallurgical site specialized  in the  treatment  of cassiterite.  Despite  being  the prehistoric  layers  disturbed by  contemporary,  1950´s,  mining  works,  it  was  possible  to  document  traces  of  prehistoric mining,  remains  of  elliptical  huts  and  some  of  the  steps  of  the  proposed  operational  chain for the mining and processing of tin in the site. The chronological/cultural context for the archaeological register was placed between the 9th-8th/7th-6th  centuries B.C., during which the present-day Extremadura territory was conformed as a Tartesian periphery. Also, the preliminary metallurgical results of the recent (summer 2013, after its declaration as a “Geosite” within the “Villuercas-Ibores-Jara” Geopark) archaeological  excavation in Cerro de San Cristóbal are presented

Copper Induces Damage, Oxidative Stress and Cell Death in Endothelium of Chronic Intoxicated Wistar Rats

Reactive Oxygen Species (ROS) are part of the functional balance of various systems, they can generate cellular damage by oxidative stress associated with disease processes such as atherosclerosis, cardiovascular disease, diabetes, and aging. Some studies report that copper induces damage to the endothelium, which could be associated with cardiovascular pathologies. This study was an experimental comparative, prospective, longitudinal, and controlled clinical trial in a murine animal model. Twenty-four male Wistar rats were included, the distribution of the groups was time-depending chronic exposition to copper, and a control group. Results show gradual alterations in the groups treated with copper: areas with loss of the endothelium, signs of disorganization of smooth muscle fibers in the tunica media, as well as areas with the fragmentation of the elastic sheets. A significant statistical difference was observed in the active- Caspase-3 analysis expression in the aortic endothelium and endothelium of the capillaries and arterioles of the lung between the control group vs 300 ppm of copper. Expression of eNOS was detected in the endothelium of the aorta and vessels of the lung. Our study shows histological changes in the walls of the great vessels of intoxicated rats with copper, and the increment of inflammatory cells in the alveoli of the study model, mainly at a high dose of copper exposition. These results will be useful to understand more about the mediators involved in the effect of copper over endothelium and cardiovascular diseases in chronic intoxication in human
