July/ 2013 THE TRUTH ABOUT THE EXEMPTION CLAUSE! BY : Jusniza Abdul Jamal The most frequently encountered exemption clauses are in the second category. They generally operate to exclude liability for breach of contract or for negligence or sometimes even to limit liability to a specified sum. An example of this can be seen in the wordings of section 4 of the Innkeepers Act 1952 which limit the hotels’ liability for loss or injury up to RM500, excluding animals (pets) and vehicles belonging to their guests. This means that a guest is unable to claim any compensation more than RM500 for any missing property while staying at the hotel unless the loss or damage was due to the default or neglect of the hotel or its employees. In some cases, the exemption clause is not even stated in a formal contract but is specified or referred to in an informal tickets or a notice displayed at certain parts of a building (as mentioned earlier). Normally, the courts are reluctant to treat such terms as part of a contract unless reasonable steps were taken to bring it to the notice of the parties affected. In the case of Thornton v. Shoe Lane Parking Ltd., the plaintiff’s car was damaged whilst being parked in defendant’s premises. The plaintiff received a ticket containing an exemption clause from an automated machine at the entrance of the garage. The court held that the plaintiff was not bound by the exemption clause printed on the ticket as the contract was concluded when the car was driven to the entrance of the garage. The ticket was issued after the conclusion of the contract. In other words, the ticket was not part of the contract between the plaintiff and the defendant. The decision of the above case was certainly favourable to In cases where there are no formal contracts, ‘tickets’ are normally intended as a mere acknowledgement of payment. This has been seen in the case of Chapelton v. Barry UDC where the plaintiff was given a ticket after hiring a deck chair from the defendant. The plaintiff was unaware of the fact that the ticket contained an exemption clause. Nevertheless, the court allowed him to sue the defendant for injury when the deck chair gave way beneath him because the ticket was a mere receipt issued as proof of payment and not intended to have any contractual effect. However, if the court is satisfied that a notice is reasonably sufficient to bring the customers’ attention to the exemption clause, then the defendant might be able to exclude any liability for loss or injury caused to their customers. Even though parties to a contract are able to impose unfair terms excluding them from liability, the courts are very strict in interpreting exemption clauses. The wordings must be very clear and unambiguous in a way that the parties affected would understand the scope of the liability it sought to exclude especially where negligence is involved. In any event of doubt or ambiguity as to the meaning and the scope of the exemption clause, the courts would apply the contra proferentum rule. This means that the courts will construe forcibly the words against the party putting forward the document. In Hollier v. Rambler Motors Ltd., the court held that the words “the garage is not responsible for damage caused by fire to customers’ cars” did not exclude liability for damage to a customer’s car caused by fire due to the garage’s negligence. This case shows that it is not easy to exclude liability for negligence especially where there is a duty of care involved. In light of the above discussion, it appears that generally an exemption clause is only effective when it is properly incorporated into the contract and the parties affected are aware of it and understand the scope it covers. However, there is still hope for the victims in cases involving gross negligence where the courts will definitely strive to uphold justice in any way they can. k mi ak a tin de First of all, let us look at the definition of the word ‘exemption clause’ offered by the Oxford Concise Dictionary of Law. ‘An exemption clause’ is defined as a term in a contract purporting to exclude or restrict liability of one of the parties in specified circumstances. Sadly, the Malaysian Contracts Act 1950 contains no provision dealing with exemption clauses yet. Therefore, the Malaysian courts still rely heavily on the English common law in this particular aspect. Basically, there are two types of exemption clause. It is a term of a contract that attempts either to modify the obligations under the contract or to limit or exclude liability of a party which would otherwise arise as a result of a breach of that party of his primary obligation. the customers generally. However, the rule regarding ‘tickets’ is completely different when it comes to ‘airline tickets’. In Malaysian Airlines System Bhd. v. Malini Nathan & Anor, a passenger tried to sue the airline for overbooking. The court held that MAS was not in breach of contract for failing to accommodate the passenger on the said flight. They were entitled to rely on the clause printed on the ticket which stated that the times shown in the timetables or elsewhere are not guaranteed and form no part of the contract. It seems here that airline ticket is treated as a contract and the parties are bound by the conditions printed on it. This may due to the fact that their services are rendered sometime in the future and the flight schedules could often change due to unforeseen circumstances. 1 bule “Park at your own risk!”. “The management of this hotel is not responsible for any loss of or damage done to any vehicles parked here.” Looks familiar? These are just some of the examples of exemption clauses that we often encountered when we enter a parking space at the hotels or shopping malls. How effective are these clauses and do you feel that they are unfair to us? Is it true that we are not entitled to claim any compensation for any loss of or damage done to our vehicles? OrganicTransistor Transistor Organic Written by : Nordiana Mukahar & Nor Syamaliah Ngah Over the years, the drastic progress of transistor technology from micron to nano scale of channel length size has revolutionized the field of electronic and paves the way for smaller and cheaper devices. Ever since the transistor was discovered by three scientists from America at Bell’s lab in 1947, it has changed the history in a big way for computer and all electronics. Originally, the first computer was about the size of a large room and its size reduced to a palm size with the invention of transistors. It was claimed by the researchers and scientists as one of the greatest innovation in 20th century. The evolution of transistor continues in which the latest finding demonstrated that organic transistor will be new paradigm in the electronic field replacing inorganic transistor. Have you imagined that the television at your home can be folded or rolled up? Wearing the smart phone made of electronic paper, flexible and the phone can curl up into a ball? All these have been realized by the new invention of organic transistor which uses an organic compound in its channel. Researchers have been focusing on the creation of more efficient and natural ways for human beings to interact with the complex information processed in these high-performance devices and biodegradable electron Application of organic transistor (Source : www.sony.net) 2 ak tin ade bule Organic transistor is transistors with organic semiconductor in their semiconductor layer. An organic material is one with molecules consisting of a carbon (C ) skeleton linking together other elements. These materials are similar to resins, such as plastics and vinyl. Organic field effect transistor (OFET) can be prepared by either vacuum evaporation of small molecules or by mechanical transfer of a peeled single- crystalline organic layer onto substrate and it have been fabricated with various geometries. In contrast with organic transistor, an inorganic transistor is made from silicon (Si) and silicon crystals are extremely hard. Organic substances on the other hand are light and flexible, making them ideal for creating flexible, human-friendly devices. A few giant companies have been making their move to produce the so called biodegradable electronic devices using organic transistor, for example Sony has demonstrated its ability to create flexible, dropproof displays by using organic transistors on plastic substrates to create drivers for a flexible transmissive LCD display and a flexible OLED display. Such a display could also be dropped without breaking, rolled up, or folded unlike LCD and OLED displays made from inorganic transistor which is hard to bend. Researchers from Queens’s University in Kingston Ontario Canada have recently came up with a paper thin and flexible smartphone that is able to alter its physical body shape to give notification of call, message, email and etc. It is still very much in the prototype stage and will be available to consumers within the next five to ten years. The organic transistor is a new technology that is still in the early stages of its evolution. There are a few major issues remaining to be resolved before adopting it for widespread use and applications. Organic material suffers from thermal instability due to its low melting temperatures and large thermal expansion coefficients that can cause thermal degradation. One of the differences between organic transistor and inorganic transistor is the simplicity of the method used to produce them and temperature at which they are fabricated. Inorganic transistors require massive vacuum systems and complex manufacturing processes and require high temperatures (500-1,000ºC). On the other hand, organic transistors can be produced using printing application method between room temperature and 200ºC. However, most of organic transistors operate at high voltages (> 40V) as compared to the inorganic transistor. Comprehensive development and intensive research needs to be conducted on the printing process, device fabrication and design methods to improve the performance and stability of organic transistor technology.

Mammography is very sensitive in the detection of microcalcification. However, the specificity of mammogram remains low because there are some benign calcifications that cannot be distinguished from those indicating malignancy (Moon et al., 2000). Although mammography is the most powerful modality for early detection, it is hazardous for use in young women due to x-ray exposure. Another modality of image diagnosis is ultrasound echo technique, but it is not as powerful in detecting breast cancer as mammography. Ultrasound scanning or ultrasound imaging is also known as sonography. It is an imaging technique that uses sound waves to look inside the body. In addition, to view the image inside the body, a clinician spread a thin lubricating jelly over the breast and the hand-held. Then ultrasound transducer used to obtain the image sending out ultrasonic sound waves at a high frequency. Ultrasonic sound waves move through the skin and other breast tissues when the transducer is placed on the breast at certain locations and angles. The sound waves bounce off the tissues like an echo and return to the transducer. The transducer picks up the reflected waves, which are then converted into an electronic picture of breast. According to Ikeda (2004), ultrasound is a useful in assisting mammography for the diagnosis and management of breast disease. It is used to distinguish cysts from solid masses, evaluate palpable lumps in young women and provide guidance for percutaneous biopsy. Ultrasound is commonly used as the first modality to evaluate palpable finding in young patients. Women younger than 30 years have breasts that are composed of mostly glandular tissue. These glandular tissues may hide a cancer (Ikeda, 2004). Palpable masses in women with radiographically dense breast on mammography can be evaluated by using ultrasound. Breast tissue is composed of mostly dense fibro glandular tissue in young women and the dense tissue turns into fat with age (Ikeda, 2004). Besides that, ultrasound is used to characterize a mass initially detected by mammography as cyst or solid. Cysts are smooth and mobile and are most common breast mass (Ikeda, 2004). Cysts are not premalignant and may cause lump that mimic round cancer on physical examination or mammography (Ikeda, 2004). However the radiology info (2008), states that sonography still has limitations where the image does Although sonography has limitations, it has some benefits. The benefit of identifying abnormalities by using sonography are that, sonography are non invasive, painless, widely available, easy to use and less expensive than other imaging methods. Sonography uses no ionizing radiation. In addition to that, sonography give a clear picture of soft tissue which does not show up well on x-ray images and sonography can help detect lesions in women with dense breasts. Since the mammogram and sonography procedures complement each other, they can be used for patients of 30 years of age or older. Sonography alone is also sufficient to determine whether on area of concern needs a biopsy or not. REFERENCES Ikeada, D. M. (2004). Breast Imaging. California: Stanford University School of medicine.

In some cases, when sonography is not able to determine whether a mass is cancerous, a biopsy will be recommended. Sometimes calcifications seen on mammography cannot be seen in sonography. Sonography is one of the tools used in breast imaging, but it does not replace annual mammography and careful clinical and self breast examination. ABNORMALITIES IN BREAST Nursyazni Binti Mohamad Sukri, Noor Khairiah Binti Razali Breast cancer is a common disease in women. It is a condition where the cells in the body grow, change and multiply out of control. The group of cells that are dividing rapidly may form masses. Tumor is the mass. It can be malignant (cancerous) or benign (non cancerous). Breast cancer refers to the erratic growth proliferation of cells that started in breast tissue and a malignant tumor that has developed from cell in the breast. In Malaysia, breast cancer is the most common female malignancy. Its incidence in Malaysia in 2000 was 41.9 cases per 100000. In 2002, 4337 cases of breast of breast cancer were reported to the National Cancer Registry with an incidence rate of 52.8 per 100000 and accounting for 30.4% of all diagnosed malignancies in Malaysia women (Omar & Yip, 2005). The breast is a unique organ. It is not fully formed at birth, but starts to involutes long before menopause. The breast is attached to the front of the chest wall on either side of the breast bone or sternum by ligament. They rest on the major chest muscle. According to the Imaging (2008), the breast consists of fatty tissues, mass of glandular and fibrous tissues positioned over the pectoral muscles of the chest wall. A layer of fatty tissue surrounds the breast stands and extends throughout the breast. The fatty tissue gives the breast a soft consistency. The milk glands of the breast produce milk and transfer to the nipple through the ducts. Pink or brown pigmented region surrounding the nipple are called areola. Each breast contains 15 to 20 lobes arranged in a circular fashion. Lobes are covered by fat and it will give the breast its size and shape. Figure 1 below show the breast anatomy. Figure 2: Breast Phantom Setting Source: (Supertech) This phantom consists of a group of vertical plane targets. There is a target per group that has 18cm deep range and 2cm spacing from each other. The material used for vertical plane target is 0.1mm nylon monofilament. Besides that, the phantom also consist a group of horizontal plane targets. The number of target per group is 7 with 9cm of depth range and 2cm spacing of each other the material that used for horizontal plane targets is 0.1mm nylon monofilament. Near field targets and axial resolution targets are also an element of ultrasound phantom image. A group of axial resolution target consist 12 of target with 3mm depth the spacing target are 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm. Material used for both group targets is 0.1mm nylon wire. On the other hand, phantom also consists of cyst as an anechoic target and solid as a high contrast target with 8mm diameter of target and 4cm depth of target. The contrast of anechoic target is -15dB to background material and the contrast of high contrast target is +15dB to background material (McNitt, 2009). Figure 1: Breast Anatomy Source: (National Cancer Institute, America) Many women have at least one calcification that can be seen on mammogram. Breast calcifications are usually benign but certain pattern such as tight cluster with irregular shape may indicate breast cancer. There are two types of calcification namely microcalcification and macrocalcification. Macrocalcification is almost benign and required no further follow up but additional mammogram and a biopsy may be needed if they appear suspicious. 4 An example of phantom breast is shown in Figure 2. This phantom is designed with 0.5 dB/cm/MHz of attenuation coefficient and speed of sound of 1540m/s. ak tin ade bule A phantom refers to a test object used to stimulate radiographic characteristics of compressed tissue and it contains component will can radiographically model aspects of breast disease and cancer. By using this phantom, characteristic of abnormalities in the breast can be studied. Among the test that can be used to detect and diagnose breast cancer are Breast Self Exam (BSE), Magnetic Resonance Imaging (MRI), Estrogen and Progesterone Receptor Test, Mammogram, Biopsy and Ultrasound.
