Resistive features

Each retail package is required to contain a statement that is prominently placed so that consumers are alerted to the specific tamper-resistant feature of the package. The labeling statement is required to be so placed that it will be unaffected if the tamper-resistant feature of the package is breached or missing. 

In U.S. EPA Office of Radiation Program s New House Evaluation Program (NEWHEP), two builders in the Denver area, two in Colorado Springs, and one in Southfield, Michigan, installed various radon-resistant features in houses during construction. A sampling of subsequent measurements of indoor radon, adjacent soil gas radon, and soil radium content is summarized in Table 31.6.36...

Pumps come in a bewildering array of shapes, sizes, capacities, head characteristics, chemical and corrosion resistance features, materials of construction, and prime mover types. The choice of a specific pump for a specific application is best made in consultation with individual vendors who can provide detailed data about their product. Ultimately all choices are based on a cost optimization. 

In 2004, Toray Industries, Inc. succeeded in developing the world s first plasticiser-free flexible PLA film using Toray s own nano-structure control technology for biaxially oriented films. This film, without losing the transparency and heat resistance features of PLA, has achieved superior flexibility levels, meaning it could be used as packaging films such as wrapping films. Toray are confident that the environment-friendly features of PLA film are expected to spur widespread demand in the future.

Figure 2C). Likewise, Figure 7C shows the spectrum of the partially etched tantalum surface whose composition appears similar to the virgin surface (Figure 7A). There is evidence of some fluorine in the surface resulting from the probable ethant species. Figure 10 is a micrograph of the resist features at the conclusion of etching. It shows no surface irregularities, and the features are little changed from their unprocessed state. Under these conditions, the substrate can be completely etched with minimal loss of PBS.

Fusion Inhibitors Novel drugs from a new class with different resistance features than the other three classes. Fusion inhibitors bind to a region of the HIV-1 virus that inhibits fusion of the virus with CD4 cells. This inhibition reduces viral replication slowing progression from HfV infection to AIDS. 

Next, the pattern is developed by dissolving the exposed parts of the pattern in the correct solvent. The quality of the pattern (contrast) depends on both the exposure and the development time, both of which must be experimentally determined for different resist systems and substrates. Once the pattern has been exposed and developed, the actual catalytically active metal(s) or oxide(s) is vapor deposited both within the holes in the pol3mier and on top of the polymer (step 5). This metal (or oxide) film should be discontinuous at the pattern boundaries in order to make possible the liftoff the remaining resist. This requires that the resist layer is thicker than the deposited film, and that the developed resist features have an undercut or negative profile...

This process operates in the aqueous phase at 250 C and 65.10 Pa absolute, in the presence of cobalt iodide as catalyst The high-pressure reactor lined with hastelloy C for corrosion resistance features internal agitation of the liquid obtained by gas injection ( air lift type). It is continuously supplied with a stream of methanol, dimethyl ether, carbon monoxide if required, and water preheated to between 40 and 80°C. The amount of water added is one-third of that of methanol by weight The arid mixture and the unreacted gases are collected at the top of the reaction tower, cooled, and brought to 1.10 Pa absolute in a flash drum. The methyl iodide and header components in, the Hashed gases are recovered by scrubbing with methanol feed. ... 

Loss of torque against time has been well documented with plastic caps on plastic bottles. This does not necessarily mean that the closure becomes ineffective, but there are occasions when a low torque only needs the vibration effects of transportation to become an unsatisfactory (loose/leaking) closure. Certain tamper-evident/resistant features such as sealed diaphragms and ratchet-type closure systems are likely to overcome such problems. Having the right combination of plastics may also eliminate or reduce this loss of torque. However, there is the converse where the use of the incorrect combination of plastics, or plastics with undesirable constituents such as lubricants, mould release agents, internal release agents, may actually exacerbate the loss of closure torque. This loss may be associated with thread forms, area of thread contacts, cold flow or creep of plastics involved, lubricants, etc. 

However, further improvements should not be overlooked. New laminations and configurations have recently become available to improve further the child-resistance features of both blisters and strips. In the USA these are typically peelable... 

Other than being used to pack solid dose medication, blisters or bubble packs, as they are often known, may find further applications in pharmaceutical packaging. These may be as a protective overwrap against physical damage, to prevent ingress or egress, to aid display or to act as a tamper-evident/tamper-resistant feature (i.e. packs which are not involved with the solid dosage form). 

When the minimum dimensions of a resist pattern are <100 nm, their dimensional tolerances approach the scale of the molecular components of the film. At this level, LER, random fluctuation in the width of a resist feature, may limit the advancement of lithography. Possible contribution to LER include polymer molecular weight, molecular weight distribution, molecular structure of resist components, inhomogeneity in component distribution within the film, statistical effects influencing film dissolution, intrinsic properties of the imaging, chemistry, image contrasts of irradiation, etc. 

For all other products subject to this requirement, including two-piece, hard gelatin capsules that are sealed by a tamper-resistant technology, a minimum of one tamper-resistant feature is required. 

A synergistic effect of hyperthermia of 42 to 45°C was observed when delivered after or simultaneously to PDT [87-90] which could be of advantage in treating brain tumors. The PDT might be of advantage in the treatment of tumors not responding to chemotherapy because cells which express multi-drug resistance features are less likely to be cross-resistant to PDT [91]. 

At temperatures higher than 120-130°C, hardening and flow of the resist patterns are two competing processes in DNQ/novolac resists. Figure 11.46 shows novolac resist patterns before and after postbake the features postbaked at very elevated temperatures (130°C) have deformed to a rounded shape due to surface tension. The temperature at which the resist feature starts to deform is termed the flow temperature of the resist. Large features are more susceptible to thermally...
