UNIVERSITY OF GRANADA USES CISCO TECHNOLOGY TO ACCELERATE TEACHING AND INVESTIGATIVE CAPACITY

Escrito por

Cisco (NASDAQ: CSCO) has announced that the University of Granada (Spain) has renovated its network infrastructure with the Cisco Catalyst® 6500 Series Switches. The upgrade incorporates higher-capacity processors and 40 Gbps Gigabit Ethernet connectivity cards in order to establish aggregated links and obtain a connection to the 160 Gbps nucleus of the network backbone. The university thus becomes the first academic organisation in the world to reach this capacity using Cisco Catalyst switches.
Thanks to this capacity — up to 16 times as great as that of most other Spanish universities — the University of Granada’s researchers, students and personnel are able to access the teaching and research resources at maximum speed, making it easier for researchers to work uninterruptedly with centres located within and outside Spain. Offering new services with high bandwidth consumption but minimum latency, the network has been designed to take into account the requirements of high availability, fault tolerance and highly secure access to data, greatly optimizing reaction to contingencies.

 

The University of Granada comprises 70 buildings spread over eight campuses (five in Granada, one in Ceuta, another in Melilla and one virtual wireless one) interconnected by 2,000 kilometres of its own fibre optic cable. With approximately 85,000 users consisting of students and personnel, it is the third biggest university in Spain and the first to locate the network at the centre of its new development; in 2005 it had already migrated to ATM connectivity with 10 Gbps links, again based on Cisco Catalyst switches, and was the first Spanish university with wireless coverage for all its campuses.

Key Highlights

The new-generation network — known as RedUGRNova — consists of Cisco® routing, switching and safety solutions, including: Catalyst 6500 Series Switches that were updated with Catalyst 6904 40 GE cards; Cisco Nexus® 5500 Series Switches to interconnect the two main university data centres and to unify the LAN and storage networks, including transport via Fibre Channel on Ethernet (FCoE); Cisco ASA firewalls; and the unified Cisco Prime™ Infrastructure management console. The Cisco Catalyst 6500 Series Switches also incorporate the Supervisor Engine 2T, that can increase the Cisco Catalyst 6500 advanced service modules which add capacities for balancing load and monitoring traffic capability from 720 Gbps to 2 Tbps, quadrupling the number of devices or users that can connect to a network up to 10,000.

These solutions allow the university to simplify control and resource monitoring at the same time as it provides internal support for the exponential growth in the number of users and high-output applications (HPC, or high-performance computing) requiring greater network capacity. Such HPC applications include cloud services, IP voiceover, high-definition videoconferencing, instant messaging, e-learning, digital library, Internet television (UGR Media) and storage on SAN networks.

Likewise, the new infrastructure — which supports the IPv6 protocol — is designed to facilitate interconnection with the Pan-European research network GEANT via the IRIS-NOVA network, allowing them to work together uninterruptedly and with minimal latency between researchers from the different faculties and schools and other researchers all over the world.

The project has been financed with funds from the European Union, while Acuntia, a Cisco Gold Certified Partner, has integrated the new network infrastructure in the University of Granada.

Thanks to the deployment of its own fibre optic cable to interconnect all of its campus and buildings, thus allowing to set-up the network RedUGRNova, the University of Granada will obtain an estimated savings of approximately 100,000 euros per month according to its own calculations.

Antonio Ruiz, networks service and communications manager in the University of Granada: «Cisco’s technology means that we have a single network with maximum availability, scalability and safety all on our campus, enabling us to simplify integration of services, unify its management, and guarantee internal and external communications independently of the amount of bandwidth used now and in the future.»

Marcos Jimena, sales director for Borderless Networks in Cisco España: «We are delighted to help the University of Granada become a worldwide benchmark in terms of network capacity. Due to the criticality of its services and the need for high availability and redundancy in teaching and research projects, the new network is based on architecture involving a double chassis in each node, combining the power of the Cisco Catalyst switches with the innovative Cisco Nexus switching technology, benefiting both the University and its users as well as the associated research centres.»

Drug abuse impairs sexual performance in men

Escrito por

Researchers have found that drug abuse negatively affects sexual performance in men even after years of abstinence.
This finding contradicts other studies reporting that men spontaneously recovered their normal sexual performance at three weeks after quitting substance abuse.
The study included 905 men of which 550 had been diagnosed with alcohol, cocaine, cocaine and alcohol, heroin, marihuana and speedball (cocaine and heroin) addiction.
In this study, researchers at the University of Granada, Spain, and Santo Tomas University in Colombia assessed the sexual performance of 605 men, of which 550 had been diagnosed with alcohol, cocaine, cocaine and alcohol, heroin, marihuana and speedball (cocaine and heroin) addiction. The remaining 356 men were included as controls.
Assessing Four Areas
The researchers examined and evaluated four areas of sexual performance: sexual desire, sexual satisfaction, sexual arousal and orgasm. The study revealed that the study group had a moderately to significantly impaired sexual performance as compared to controls. Additionally, the researchers separately examined the effects of the different substances on sexuality. For instance, speedball and cocaine abuse prevailingly affect sexual pleasure, while they slightly affect sexual desire. Indeed, cocaine users have very high sexual desire during peak periods of drug abuse.
Alcohol is the drug which most affects sexual arousal (erectile capacity). This is the first study to reveal the permanent effect of substance abuse on sexuality, even after long abstinence periods. Finally, orgasms are prevailingly impaired by heroin, cocaine, alcohol and speedball.
The study has been published in the Journal of Sexual Medicine in the USA.

Semen quality of young men in south-east Spain down by 38 percent in the last decade

Escrito por

The first comparative study on the evolution of sperm quality in young Spanish men over ten years, headed by researchers at the University of Murcia, reveals that spermatozoid concentration in men between 18 and 23 years in the regions of Murcia and Almeria has dropped by an annual average of 2%.
The suspicion that the semen of Spanish men is losing quality now takes force in the case of young men from Murcia and Almeria.
The ‘Andrology’ journal has published a multidisciplinary and international study, headed by the Department of Preventative Medicine and Public Health of the University of Murcia (UMU), which demonstrates that «total sperm count and concentration has declined amongst young men in the south-east of Spain in the last decade.» More specifically, the decrease amounts to 38%.
The lead researcher, Alberto Torres Cantero, explains to SINC that the study involved «comparing the results obtained by the Medical Research Centre of the University of Granada from the semen of 273 men from Almeria between 18 and 23 years, collected between 2001 and 2002, with those samples collected ten years later by 215 undergraduates from Murcia, all the while ensuring that both sample groups had the same age range and similar characteristics.»
The analysis shows that the number of spermatozoids is significantly lower in the subjects from Murcia compared to the participants from Almeria. Average concentration goes from 72 million spermatozoids per millilitre in 2011 to 52 million/ml in 2011, according to Torres Cantero, professor of Preventative Medicine and Public Health at UMU.
Another relevant result is that «40% of those university students analysed in Murcia suffered from alterations in at least one semen parameter (morphology, mobility). Furthermore, all sperm indicators are below the norm in 15% of the sample,» states Jaime Mendiola, professor at the UMU and first signatory of the study.
Clinic trails are needed
«Before there were no well performed studies to detect a change in sperm quality in Spain,» explains Torres. Its main limitation is that it only makes reference to one geographic area and cannot be extrapolated: «We do not know if the same has occurred in other parts of Spain,» outlines the researcher. There is little likelihood that the study will be carried out in other regions «because there are no similar semen quality studies in the young and healthy population.»
Nonetheless, the fact that semen has worsened does not necessarily mean that the number of infertile men has increased. As Torres clarifies, this study measures semen quality and not fertility, «for which specific criteria established by the WHO are used.»
Despite this, Mendiola feels that these data are worrying because «it has been verified in recognised studies that a concentration lower than 40 million/ml makes conception more difficult. If the rate of loss we have outlines continues, with an average decline in quality of 2% per year, the sperm of young men could reach this danger level of 40 million/ml in a very short space of time.»
For this reason, the authors stress the urgency to promote «clinical trails that identify effective prevention actions for counteracting this negative trend via lifestyle changes.»
«We believe that some prevention actions involving lifestyle improvements, such as a healthier diet, could increase sperm quality,» outlines Alberto Torres. «But we still lack rigorous scientific information to propose them neither in the clinical field nor at a population level. If we could identify those actions, we could improve sperm quality.»

This study enjoyed the participation of the Department of Preventative Medicine of New York’s Mount Sinai Hospital, the Reproduction Department of the University of Copenhagen, the Spanish universities of Granada and Miguel Hernández (Elche) and Dexeus and Fertilidad Roca clinics in Murcia.

The suspicion that the semen of Spanish men is losing quality now takes force in the case of young men from Murcia and Almeria.
The ‘Andrology’ journal has published a multidisciplinary and international study, headed by the Department of Preventative Medicine and Public Health of the University of Murcia (UMU), which demonstrates that «total sperm count and concentration has declined amongst young men in the south-east of Spain in the last decade.» More specifically, the decrease amounts to 38%.
The lead researcher, Alberto Torres Cantero, explains to SINC that the study involved «comparing the results obtained by the Medical Research Centre of the University of Granada from the semen of 273 men from Almeria between 18 and 23 years, collected between 2001 and 2002, with those samples collected ten years later by 215 undergraduates from Murcia, all the while ensuring that both sample groups had the same age range and similar characteristics.»
The analysis shows that the number of spermatozoids is significantly lower in the subjects from Murcia compared to the participants from Almeria. Average concentration goes from 72 million spermatozoids per millilitre in 2011 to 52 million/ml in 2011, according to Torres Cantero, professor of Preventative Medicine and Public Health at UMU.
Another relevant result is that «40% of those university students analysed in Murcia suffered from alterations in at least one semen parameter (morphology, mobility). Furthermore, all sperm indicators are below the norm in 15% of the sample,» states Jaime Mendiola, professor at the UMU and first signatory of the study.
Clinic trails are needed
«Before there were no well performed studies to detect a change in sperm quality in Spain,» explains Torres. Its main limitation is that it only makes reference to one geographic area and cannot be extrapolated: «We do not know if the same has occurred in other parts of Spain,» outlines the researcher. There is little likelihood that the study will be carried out in other regions «because there are no similar semen quality studies in the young and healthy population.»
Nonetheless, the fact that semen has worsened does not necessarily mean that the number of infertile men has increased. As Torres clarifies, this study measures semen quality and not fertility, «for which specific criteria established by the WHO are used.»
Despite this, Mendiola feels that these data are worrying because «it has been verified in recognised studies that a concentration lower than 40 million/ml makes conception more difficult. If the rate of loss we have outlines continues, with an average decline in quality of 2% per year, the sperm of young men could reach this danger level of 40 million/ml in a very short space of time.»
For this reason, the authors stress the urgency to promote «clinical trails that identify effective prevention actions for counteracting this negative trend via lifestyle changes.»
«We believe that some prevention actions involving lifestyle improvements, such as a healthier diet, could increase sperm quality,» outlines Alberto Torres. «But we still lack rigorous scientific information to propose them neither in the clinical field nor at a population level. If we could identify those actions, we could improve sperm quality.»

Drug Abuse Impairs Sexual Performance in Men Even After Rehabilitation

Escrito por

A new article reveals that alcohol is the drug that most affects sexual arousal (erectile capacity). In addition, the researchers observed that men did not improve their sexual performance when they stopped drinking alcohol. The study included 905 men of which 550 had been diagnosed with alcohol, cocaine, cocaine and alcohol, heroin, marijuana and speedball (cocaine and heroin) addiction.

Researchers at the University of Granada, Spain, and Santo Tomas University in Colombia have found that drug abuse negatively affects sexual performance in men even after years of abstinence. This finding contradicts other studies reporting that men spontaneously recovered their normal sexual performance at three weeks after quitting substance abuse.
The results of this study have been published in the Journal of Sexual Medicine, the official journal of the International Society for Sexual Medicine. The authors of this paper are Pablo Vallejo Medina -a professor at Santo Tomas University, Colombia- and Juan Carlos Sierra, a professor at the University of Granada.
In this study, the researchers assessed the sexual performance of 605 men, of which 550 had been diagnosed with alcohol, cocaine, cocaine and alcohol, heroin, marihuana and speedball (cocaine and heroin) addiction. The remaining 356 men were included as controls.
Assessing Four Areas
The researchers examined and evaluated four areas of sexual performance: sexual desire, sexual satisfaction, sexual arousal and orgasm. The study revealed that the study group had a moderately to significantly impaired sexual performance as compared to controls.
Additionally, the researchers separately examined the effects of the different substances on sexuality. For instance, speedball and cocaine abuse most frequently affect sexual pleasure, while they slightly affect sexual desire. Cocaine users have very high sexual desire during peak periods of drug abuse.
Alcohol is the drug which most affects sexual arousal (erectile capacity). This is the first study to reveal the permanent effect of substance abuse on sexuality, even after long abstinence periods. Finally, orgasms are prevailingly impaired by heroin, cocaine, alcohol and speedball.
This study was conducted thanks to the collaboration of several Spanish rehabilitation institutions: the Asociación Ciudadana de Lucha contra la Droga (A Coruña), Centro de Atención a las Drogodependencias de Arganzuela (Madrid), Centro de Atención a las Drogodependencias de San Blas (Madrid), Institut de Neuropsiquiatria i Addiccions del Parc de Salut Mar-Hospital del Mar (Barcelona), Fundación Noray-Proyecto Hombre Alicante (Alicante), Unidad Municipal de Atención a Drogodependientes (Santiago de Compostela), Proxecto Home Galicia (Galicia), Proyecto Hombre Granada (Granada), y el «Cortijo Buenos Aires» (Granada).
