Strengths and drawbacks

Although there are a variety of wavelength selection methods available, the vast majority of Raman instruments utilize either dispersive or Fourier transform spectrometers. These are shown schematically in Fig. 1.6. The high throughput and spectral resolution obtainable from these instruments make them obvious choices for Raman spectroscopy however, each has specific strengths and drawbacks which make them more suitable in specific applications. 

Managers often view performance appraisals as an undesirable task, but careful planning and implementation should make them less onerous. Performance appraisals are closely finked to employee motivation, performance, commitment, and turnover. Numerous systems are available, each ofwhich has its strengths and drawbacks. The formal appraisal must be accompanied by frequent and substantive informal feedback. The appraisal interview is key to the success of the appraisal system. The allocation of organizational rewards must be finked closely to the results of the appraisal process. 

As a group, second generation antidepressants are also distinctive for their unusual strengths and drawbacks. Since many of these drugs have fewer and more tolerable side effects, they are, for select populations, more popular than SSRIs. Wellbutrin, in particular, has received a substantial amount of attention because, unlike SSRIs, it does not cause sexual... 

Sections 7.2 and 7.3 will review the functionality of ChG glasses in thin-film and fiber-sensing applications, with a focus on how this functionality is impacted by the choice of ChG constituents. The strengths and drawbacks of these sensing approaches will be discussed, as some ChG compositions are well known for limited chemical and temperature stability, as well as high photosensitivity, which can make them excellent candidate material systems for use in some sensing regimes and environments but preclude their use in other applications. 

Recent developments in mass spectrometers have created a situation where many different mass spectrometers are suitable for non-target analysis, each with their specific strengths and drawbacks. 

Each investment metric has strengths and limitations. For example, the simple payback time indicates the time required to recover the investment, hut it ignores any benefits that may occur after the payback time, so measures offering many years of benefits appear no better than short-lived ones. A common drawback of these investment metrics is that the price of energy must be assumed. If the energy price changes, then the payback time must be recalculated. 

Unfortunately, they can have some drawbacks, such as decreased tensile strength and modulus, pollution, toxicity, migration or environmental risks, and the local and professional regulations, standards and specifications must be studied. 

The identification of faults and drawbacks in the remediation process, as well as of strengths and advantages of these processes... 

ISEs are well suited for flow measurements because the instrumentation and signal handling are simple, the measurement is almost independent of the liquid flow-rate, the linear dynamic range is broad, the temperature dependence is not very pronounced and the measurement is selective (the selectivity is, however, a drawback in applications to chromatography). The experimental conditions are readily adjusted and often only consist of ionic strength and pH maintenance. ISEs with solid membranes usually exhibit better performance than liquid membrane electrodes and gas probes, because their response is faster and they are mechanically stronger. The most difficult problem is passivation of the electrodes in some media, for example, biological fluids or surface and waste waters. 

Hafnium has a great affinity for absorbing slow neutrons. This attribute, along with its strength and resistance to corrosion, makes it superior to cadmium, which is also used for making control rods for nuclear reactors. This use is of particular importance for the type of nuclear reactors used aboard submarines. By moving the control rods in and out of a nuclear reactor, the fission chain reaction can be controlled as the neutrons are absorbed in the metal of the rods. The drawback to hafnium control rods is their expense it costs approximately one million dollars for several dozen rods for use in a single nuclear reactor. 

However, it should be noted that using diluted electrolyte solutions imply lowering ionic strength and buffering capacity, leading to a variety of drawbacks that will be discussed later in this chapter.
