Many MNCs invest in Singapore because of our skilled and hardworking workforce.
Edwards Lifesciences started producing heart valves using cow tissue in Singapore in 2005. It recruited older workers with sewing experience, mostly women, and trained them to stitch the heart valves. The same basic skills – sewing and stitching – but what a difference in the value of the job, the standards demanded, and the rewards to the workers. Here is one telling her story. – LHL

醫療科技又一進展...
Scientists have developed a battery powered artificial heart! The device can temporarily replace the ventricles and valves, allowing patients on heart transplant waiting lists to leave the hospital. The artificial heart is powered by a small battery that fits in a backpack and can be carried around.

เปิดตัว Lamborghini Huracan EVO ลัมบอร์กินี่ ฮูราคาน อีโว ในไทย เปิดตัว 22 มีนาคม 2019 นี้
Automobili Lamborghini presents the new Lamborghini Huracán EVO: the next generation V10 super sports car, based on the prowess and performance of the Huracán Performante and incorporating next-generation vehicle dynamic control and aerodynamics.
“Lamborghini is intent on leading the advance to the highest level of super sports car technologies and driving emotion. This is the essence of the new Huracán EVO. It takes the extraordinary abilities of the Huracán Performante and combines state-of-the-art vehicle dynamic control to amplify the everyday Huracán driving experience,” says Stefano Domenicali, Chairman and Chief Executive Officer of Automobili Lamborghini. “The Huracán EVO is the very definition of evolution: it is a step ahead, redefining the segment parameters. It is remarkably easy to drive, while delivering the most responsive, sensory and agile driving experience, in every environment.”
Technological evolution amplifies driving emotion
The Huracán EVO features the 5.2 l naturally-aspirated Lamborghini V10 engine, uprated to produce higher power output and an emotional and powerful sound, with Titanium intake valves and refined lightweight exhaust system. The Huracán EVO outputs 640 hp (470 kW) at 8,000 rpm with 600 Nm of torque delivered at 6,500 rpm. With a dry weight of 1,422 kg the Huracán EVO reaches a weight-to-power ratio of 2.22 kg/hp, accelerates from 0-100 km/h in 2.9 seconds and from 0-200 km/h in 9.0 seconds. Braking from 100 km/h to 0 is achieved in just 31.9 m, with a top speed of more than 325 km/h.
Lamborghini Dinamica Veicolo Integrata (LDVI)
The Huracán EVO features new Lamborghini rear-wheel steering and a torque vectoring system working on the four wheels, while at the heart of the car is the new feature of Lamborghini Dinamica Veicolo Integrata (LDVI): a Central Processing Unit that controls every aspect of the car’s dynamic behaviour, fully integrating all of the car’s dynamic systems and set-up to anticipate the next move and needs of the driver, interpreting this into perfect driving dynamics.
Lamborghini Piattaforma Inerziale (LPI), a comprehensive set of accelerators and gyroscope sensors placed at the car’s center of gravity, has been enhanced to version 2.0. With improved precision, it monitors in real-time the dynamic vehicle attitude regarding lateral, longitudinal and vertical accelerations, as well as roll, pitch and yaw rate. The magneto rheological suspension, upgraded to version 2.0, instantaneously adapts the damping following inputs from the LPI. A new advanced traction control system together with enhanced all-wheel drive and torque vectoring, allows traction to be directed to a single wheel as required.
Enhanced Lamborghini Dynamic Steering (LDS), able to provide higher responsiveness in corners while requiring the lowest steering angles, is now coupled with rear-wheel steering in order to ensure agility at low speed, as well as maximum stability in high-speed cornering and under braking in the most severe conditions.
The unique combination of all these systems is governed by Lamborghini’s LDVI to create a super-agile and responsive car with unparalleled level of control. Processing data in real time, the Huracán EVO recognizes the driver’s intentions through steering wheel, brake and accelerator pedal inputs, engaged gear and the driving modes selected via ANIMA controller: STRADA, SPORT or CORSA.
External conditions are determined through active suspension and all-wheel drive grip estimation function. All of this information is analysed and processed by LDVI, which turns them into precise inputs for the vehicle dynamic system. A ‘feed forward logic’ is implemented via the dynamic controller, which means the car doesn’t just react, but predicts the best driving set-up for the next moment.
In STRADA, the Huracán EVO is agile and capable for driving enjoyment, whereas in SPORT it becomes playful, intuitive and extremely exciting. In CORSA the Huracán EVO is sharp, reactive and exhilarating for the most extreme driving environments, such as racetracks.
CB400 SUPER FOUR (Shebe Suparfoa and abbreviation: CB400SF) is a motorcycle of 400cc naked type that Honda Motor Co., Ltd. is putting on the market. Alias Sufoa CB400SF(NC31)
CB400SF was developed under the concept of PROJECT BIG-1. In PROJECT BIG-1, the following requirements hang.
* Adopt four strokes and four DOHC water-cooled parallel cylinder engines in
the heart.
* The style of wild sexy &.
* Possess impressed performance that enchants the mind of the running
person.
The reference is exhibited to CB1000 SUPER FOUR in the 29th Tokyo Motor Show as a model of first PROJECT BIG-1, and it is put on the market in April, 1992 afterwards in 1992.
It fought hard by sales because the style was more halfway on a practical side compared with the thing and the rival car with a little capacity of the fuel tank, and it reflected on the failure of CB-1, and CB400SF was put on the market in shape to take the style of a great car before though CB-1 was sold when HONDA till then did naked by four cylinders though CB-1 was excellent in the sports performance.
As the main change point from CB-1
* It changes from the style with a sporty feeling to the style of the old car style
of CB750F and CBX400F.
* Szasz
* It changes to a large-scale tank of the CB1100R type.
* Double disk making about reception desk brake
* The cam gear train is abolished from NC23E that is four water-cooled parallel cylinder engine that continues from CBR400R from generation to generation, the fin is added, and it installs it.
Version R appeared in the minor change, and Version S of Bikinicaulres appeared afterwards. Moreover, the model named CB400FOUR that takes the style of the CB750FOUR style based on NC31 exists, too.
Version R(version are)
Sale on March 10, 1995. Model 1 equipped with bikini caul.
Change point from STD model
* Headlight only for bikini caul &
* Silencer made of aluminum (STD is an all-in-one design of iron).
* Adoption of PGM-IG control system (electronically controlled ignition system) that synchronizes with open times of throttle and supplies the best ignition timing.
The price at the sale this time is from STD model to 100,000 yen up.
Version S(Barjon'es)
Version S removes the bikini caul from version R, and is 2 whose reception desk brake is four opposing made in NISSIN KOGYO jar caliper besides assuming a naked style.
Moreover, three where the model that the reception desk brake is equipped with four opposing made of Brembo jar caliper by the minor change exists, too.
CB400SF HYPER VTEC (NC39)
Restyling is done from NC31 on February 22, 1999, the form number becomes NC39, too and most of the body such as the body, frames, and engines has been improved.
The main change point from NC31
* HYPER VTEC that becomes the first time the first is adopted in the medium-
size car.
* It changes to the radial tire (change & swing arm change in tire strength to a size of the tire and large-scale and specification ZR cooking stoves according to it).
* Great change in exterior design
Especially, it is made the adoption of HYPER VTEC that is the changeable valve mechanism for the engine the eyeball of restyling. However, this HYPER VTEC is the one adjusting it by opening and shutting not the camshaft but the valve unlike VTEC of four wheels. When a constant rotational speed is exceeded, it comes to make it to four valves concretely, to improve fuel cost by the one that developed from the REV function provided in CBR400F before, this is named HYPER VTEC with VTEC of four wheels to differentiate though four valve valve the second grade of junior high-school has closed even a constant rotational speed.
