Abstract:

Lead-acid batteries today are commonly used in the automotive industry with a considerable span of purposes, yet historically, a primary purpose of cranking the engine at ignition which does demand a high current drainage from a battery. These high drainages later result in a health implication which can be hard to detect without the proper tools and this thesis focuses on the development of those tools.To insure the health of a battery turns out to be a handy feature for most drivers today and early signs of deterioration may even warn a user in advance of damage or failure to insure that pro

The large scale nitric acid oxidation of common sugars into their corresponding aldaric acids is being investigated as an important source of potentially useful components for industrial applications such as polymers.

Abstract:

Formaldehyde (HCHO) is a highly irritating, toxic and presumably carcinogenic chemical widely used in industry and the health-care sector. Exposure to formaldehyde in the workplace is hence an important health concern. Occupational health legislation requires employers to monitor workforce HCHO exposure at regular intervals. Methods for formaldehyde monitoring currently endorsed by the regulatory bodies are essentially laboratory based and as such, time and labor intensive. Development of simpler, more cost-effective methods which can be used in-the-field has so far been limited by the fact th

However, the significant price increase of kainic acid resulting from the disruption in the supply from its natural source, the alga Digenea Simplex, as well as inefficient synthesis of kainic acid, call for the exploration of functional mimics of kainic acid that can be synthesized in a simpler way.

Abstract:

Ostrich eggshell (OES) is ubiquitous in archaeological sites in Africa and is a favoured substrate for amino acid racemisation (AAR) geochronology, yielding consistent results and thought to approximate a closed system with respect to protein diagenesis. It was found that the intra-crystalline fraction in OES can be isolated by oxidative pre-treatment and that these amino acids are resistant to leaching and unaffected by changes in the environmental pH (between pH 5 and 9). The intra-crystalline fraction in OES therefore effectively operates as a closed system with respect to protein diagenesi

Lysophosphatidic acid (LPA) is a bioactive lipid with a plethora of biological functions, including roles in cell survival, proliferation, and migration. Although high-performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC ESI-MS/MS) technology has been used to measure the levels of LPA in human blood, serum and plasma, current methods cannot readily detect the minute levels of LPA from cell culture. In this study, a novel HPLC ESI-MS/MS method with enhanced sensitivity was developed which allows accurate measurements of LPA levels with a limit of quantitation

Abstract:

Encephalitis is a matter for serious public health concern because of the high morbidity and mortality associated with many cases. Epidemiological studies have shown that viral encephalitis (VE) is more common than the sum of encephalitis caused by all other pathogens. However, more than 95% of cases have no known cause. Thus, there is a significant need to develop a sensitive method for the diagnosis of these unknown cases. Previous sequence independent amplification (SIA) assays have proved successful in detecting new viruses in many biological samples but not in CSF samples. This may be due

Abstract:

Petroleum powered vehicles emit volatile organic compounds (VOCs) through combustion that contributes to the pollution of the environment. A technique in the 1970s was developed to decrease these emissions, especially for nitrogen oxides (NOx) and sulphuric oxides (SOx) which is called exhaust gas recirculation (EGR). The technique works by recirculating a portion of the combusted gas back into the engine, this limits the NOx and SOx emissions because of lower temperatures and less available oxygen. The problems that follow these effects is the formation and condensation of acids that corrode

Acid fracturing stimulation is one of the preferred methods to improve well productivity in carbonate reservoirs.

If the created etched surface is non-uniform, then after the treatment ends and the fracture face closes, a high conductivity path may remain in the formation, connected to the well.

碩士<br>淡江大學<br>化學工程學系<br>89<br>Magnetic BaFe12O19 powder with crystallite sizes in nanometers was produced via citric acid precursor method. Citric acid was added into an aqueous solution, containing nitrates of iron and barium in stoichiometric ratios to form the required barium ferrites, to chelate the metallic ions. The pH value of starting aqueous solutions was adjusted using NH4OH. After adding ethylene glycol into the solution and raising the solution temperature to 80℃, esterification caused the formation of the required solid precursors. The dried solid precursors were then pyrolyzed to

Applying grey prediction consolidates effective prediction and the revises discharging voltage curve that extending the lead-acid battery life. The first part of research acquires the discharging voltage of lead-acid battery. The second part establishes the grey prediction model (GM(1,1)), which evaluating the voltage of lead-acid battery when operating on discharging process. Predicted voltage value is feedback to the supervisory control

Solvent extraction and anion exchange methods are the most commonly applied techniques for the determination of Ag in water samples. In this study, solvent extraction and anion exchange techniques are combined and modified to an “organic complexation-acid extraction” method. The procedure developed involves four steps: (1) a buffer is added and the pH of the solution is adjusted for optimization purpose; (2) APDC and DDDC chelating agen

The fatty acid modified starch (FAMS) was prepared by using chemical method and Enzyme method. To characterize FAMS, the degree of substitution (DS) of FAMS was determined by alkaline titration methods and the ester bonds formed between hydroxyl groups of corn starch and carboxyl groups of atty acids were confirmed by FTIR. The thermal properties of FAMS were also investigated by using DSC. The surface polarity of FAMS was assessed by the contact angle measurement. The resistant

Rice bran, lactic acid bacteria and some fungi have the activity of Glutamate decarboxylase (GAD). Also, fungus can produce a variety of digestive enzymes. Therefore, rice bran is fermented in two stages by fungi and lactic acid bacteria to explore the effects of GABA and glutamate production. First, we compared the solid state fermentation

The damage extent of artificial teeth is relatively different. First, use a microscope to magnify 400 times to observe their slight changes on surfaces. The contact phenomena of teeth occlusion include single-point contact (incisors) and multipoint contact (molars and premolars). Ultrasonic wave technology can research the contact area.

Abstract:

Background: Sperm contain highly compact nuclei, inhibiting DNA extraction using traditional techniques. Current methods extracting sperm DNA involve lengthy lysis and no means of stabilizing DNA, hindering clinical research. Objective: We sought to optimize an efficient method of extracting high quality human sperm DNA. Methods: Sperm from three volunteers were isolated using PureCeption. We tested 1) proteinase K with DNA/RNA Shield, 2) DTT and TCEP as reducing agents, 3) QIAshredder homogenization, and 4) stability of sperm DNA fresh (baseline) or after 4 weeks of storage at 4OC in DNA/RNA
