The drug does not directly give a man an erection but it works by boosting the natural mechanism that leads to an erection. When a man is sexually aroused, certain tissues in his penis relax, allowing blood to flow in and fill the penis. Viagra helps by elevating the levels of the chemical that causes the tissues to relax. These effects were discovered accidentally. The drug was originally developed to improve blood supply to the heart in angina sufferers. Depression and anxiety: Psychological factors may be responsible for erectile dysfunction. These factors include stress, anxiety, guilt, depression, widower syndrome, low self-esteem, posttraumatic stress disorder, and fear of sexual failure (performance anxiety). It is also worth noting that many medications used for treatment of depression and other psychiatric disorders may cause erectile dysfunction or ejaculatory problems. viagra online for sale buy viagra online Pfizer viagra 50 mg online Surgery (radiation therapy, surgery of the colon, prostate, bladder, or rectum may damage the nerves and blood vessels involved in erection. Prostate and bladder cancer surgery often require removing tissue and nerves surrounding a tumor, which increases the risk for impotence) Erectile dysfunction (impotence) occurs when a man can no longer get or keep an erection firm enough for sexual intercourse. Having erection trouble from time to time isn't necessarily a cause for concern. But if erectile dysfunction is an ongoing problem, it may cause stress, cause relationship problems or affect your self-confidence. kamagra online sverige kamagra online sale Pfizer viagra 50 mg online Injection treatment - This was the most common treatment before tablets became available. It usually works very well. You are taught how to inject a medicine into the base of the penis. This causes increased blood flow, and an erection usually develops within 15 minutes. (Unlike with tablets, the erection occurs whether of not you are sexually aroused.) Dr. John R. Brinkley initiated a boom in male impotence cures in the US in the 1920s and 1930s. His radio programs recommended expensive goat gland implants and "mercurochrome" injections as the path to restored male virility, including operations by surgeon Serge Voronoff. Erectile dysfunction (ED) is when a man has trouble getting or keeping an erection. ED becomes more common as you get older. But male sexual dysfunction is not a natural part of aging.

Engineering design and analysis

We are providing engineering design and analysis expertise in:

Numerical analysis - linear static; fatigue, non-linear static e.g. buckling and ultimate strength analysis, non-linear dynamic e.g. collision and grounding modelling
Advanced structural concepts (laser welded sandwich panels and crashworthy structures)
Safety by design (risk based design and accident consequence modelling)
Optimization (local - gradient based methods, global - e.g. genetic algorithms, multi-criterion optimization)
Decision support systems (multi-stakeholder/collaborative design, preference and ship design process modelling)
Testing - test design and planning

Take a look at our list of references in Engineering design and analysis.

FE ANALYSES - MOORING EQUIPMENT

We are providing FE analyses and reports which assure that your ship equipment fits the defined standards. The analyses and reports are available for mooring equipment.

Take a look at the pricing and the availability of the FE analyses and reports of mooring equipment.

CRASHWORTHY SHIPS

as2on is one of the partners in an EU FP7 project SAFEWIN - Safety of winter navigation in dynamic ice which aims to develop an efficient ice compression and ice dynamics forecasting system. We are analysing the effect of ship structures onto risk of compressive ice damages. This knowledge is used in redesign of some parts of the structure to achieve the best possible damage resistance with reduction in structural weight.

VIBRATION AND NOISE ANALYSES AND MEASUREMENTS

We are experienced in performing forced vibration and noise analysis utilizing Finite/Boundary Element Method, providing recommendations for improvement of these characteristics to meet the IMO requirements.

COMPOSITE PATCH REPAIR FOR MARINE STRUCTURES

as2con is one of the partners in an EU FP7 project CO-PATCH Composite Patch Repair for Marine and Civil Engineering Infrastructure Applications where we are dealing with the definition of a new effective repair and/or reinforcement method for large steel structures with defects.

Together with partners we conduct laboratory testing, develop numerical simulation procedures and define application cases.

We calculated stress concentration analysis in a patch.

MODELLING AND OPTIMISATION

Our team masters FEM analyses and optimisation methods. We provided a full support in the development of an innovative design of a dredger funnel deckhouse. Design and engineering feature: parametric 3D FEM model for optimisation of panel scantlings, detailed stress assessment of all joints and their design, design for production, support in assembly and installation.

FATIGUE ASSESSMENTS OF JOINTS

Our team has been involved in various research and production projects dealing with fatigue assessments of welded joints. We have investigated geometrical variations of thick plate welded joints and their influence on fatigue assessment. We have planned and conducted fatigue tests under tension and bending loading conditions.

CRASHWORTHY STRUCTURES

One of our fields of expertise are crashworthy structures. Besides designing crashworthy ships, we have also conducted non-linear finite element simulations of a car collision in order to improve bumper crashworthiness and design.

SANDWICH PANEL DESIGN AND ASSESSMENT

We have been involved in several commercial projects to perform full suport in development of innovative sandwich structures designs. We performed evaluation of un-filled and filled sandwich structures in terms of weight savings at approximately equal strength properties. In addition to that, we conducted the elastic and the plastic assessments of a laser welded steel panel under different loading conditions such as impact pressure load up to the point of total collapse, etc.
