Characteristic of low temperature of Bi-In-Sn solder alloy (2008)

Due to the increase in the use of electronics devices within the industry, the usage of solder connections has increased. These is a concern that lead within the electronic products is considered toxic because lead has potential for leaching from landfills onto water sources and becoming a hazard to human health and surrounding environment. For this reason, replacing Sn-37Pb to free solder with low melting temperature is one of the most important issues in electronic industry. This is due to a demand on low temperature for interconnection and polymer based part component such as LCD display functionality availability at low temperature apply. In this paper, Bi-In-Sn system alloy was investigated as a potential candidate replacing Sn-37Pb. This study covers on solder characteristic such as melting temperature, thermal expansion and microstructure. Bi-In-Sn was prepared and melted in crucible. Solder was cleaned mechanical and chemical before characterized. DSC shows that, Bi-In-Sn system alloy give low melting temperature in range of 65–100°C. The addition of In to Bi-Sn system alloy lowered the melting temperature compared than Sn-37Pb. Lowest melting temperature ensures that the solder melts, forms a joint with the substrates, and re-solidifies within the shortest possible process time. From thermal expansion analysis, it was found that Bi-In-Sn gives good expansion properties to avoid mismatch between Cu pads and solder itself. EDX analysis indicated that, there are two obvious regions in Bi-In-Sn system alloy microstructure. Bright colour refers to BiIn rich phase region and dark colour refers to Sn rich phase region. BiIn rich phase region is higher compared to Sn rich phase in solder give good properties in terms of ductility.
The role of DNA polymerase beta in determining sensitivity to ionizing radiation in human tumor cells (2002)

Lethal lesions after ionizing radiation are thought to be mainly unrepaired or misrepaired DNA double-strand breaks, ultimately leading to lethal chromosome aberrations. However, studies with radioprotectors and repair inhibitors indicate that single-strand breaks, damaged nucleotides or abasic sites can also influence cell survival. This paper reports on studies to further define the role of base damage and base excision repair on the radiosensitivity of human cells. We retrovirally transduced human tumor cells with a dominant negative form of DNA polymerase beta, comprising the 14 kDa DNA-binding domain of DNA polymerase beta but lacking polymerase function. Radiosensitization of two human carcinoma cell lines, A549 and SQD9, was observed, achieving dose enhancement factors of 1.5-1.7. Sensitization was dependent on expression level of the dominant negative and was seen in both single cell clones and in unselected virally transduced populations. Sensitization was not due to changes in cell cycle distribution. Little or no sensitization was seen in G(1)-enriched populations, indicating cell cycle specificity for the observed sensitization. These results contrast with the lack of effect seen in DNA polymerase beta knockout cells, suggesting that polDN also inhibits the long patch, DNA polymerase beta-independent repair pathway. These data demonstrate an important role for BER in determining sensitivity to ionizing radiation and might help identify targets for radiosensitizing tumor cells.
Effects of duration and formant movement on vowel perception (2002)

Acoustical analysis of speech and perceptual studies indicate that the dominant acoustic correlates of vowel perception are the frequencies of the first three formants. However, most vowels are not completely steady-state (even in isolation) and formant frequencies change with variation in the surrounding consonantal context, prosodic influences, speaking rate, and vocal tract length of the talker. In the present studies, both natural and synthetic syllables ("head" and "had") were used to explore the relative potency of average formant frequencies, vocalic duration, and formant frequency movement in vowel perception. A male talker was identified whose formant frequencies, at the midpoint of the words "had" and "head", were identical. However, these tokens differed in their voiced duration and movement of the first three formants and were also highly intelligible. Since the formant frequencies at midpoint could not distinguish these two words, listeners were clearly using different/additional information to guide perception. In the first study, vowel duration was varied. Digital waveform editing was used to generate two series, one based on "had" and the other based on "head". Overall, duration had little effect on listeners' classification of the stimuli. The second study employed synthetic series in which the formant movements of the first three formants were varied between those of the natural "had" and those of the natural "head".
The effects of statics on tomographic velocity reconstructions (1992)

Abstract Seismic first arrival times from crosshole, VSP, and reversed VSP (RVSP) experiments are collectively inverted by least-squares for the velocity distribution between two boreholes. The tomographic reconstruction exhibits a large lateral velocity contrast that is not supported by the surface reflection data from the same location. After examining the traveltime residuals from the three tomographic datasets separately, we conclude that the velocity contrast is due primarily to static delays in the RVSP first arrival times. When a first-order correction is made for the statics, tomographic inversion results in a velocity reconstruction that is more consistent with the surface reflection data. To isolate the velocity errors produced by the RVSP statics, we compute a residual tomogram by subtracting the statics adjusted tomogram from the original. The residual tomogram shows that the statics introduce errors not only in the region sampled by the RVSP rays, but they indirectly contaminate other regions of the tomogram as well. We reproduce this velocity error distribution as part of a model study designed to simulate the effects of statics on tomographic velocity reconstructions. Results indicate that traveltime errors on the order of 2 percent can result in tomographic velocity errors of up to 7 percent.

Effects of yohimbine on bradycardia and duration of recumbency in ketamine/xylazine anesthetized ferrets. (1990)

Eleven adult ferrets (Mustela putorius furo) were anesthetized with ketamine hydrochloride (25 mg/kg, IM) and xylazine hydrochloride (2 mg/kg, IM). Fifteen minutes post-ketamine/xylazine injection, ferrets were treated with yohimbine hydrochloride at a dose of 0.5 mg/kg, or an equal volume of physiologic saline, intramuscularly. Each ferret served as its own control by randomly receiving both treatments with a minimum interval of 2 weeks between treatments on any one ferret. At 15 minutes post-ketamine/xylazine injection, mean heart rate measurements for both treatment groups were 27% less than the mean heart rate measurement reported for unanesthetized ferrets. Intramuscular administration of yohimbine antagonized the ketamine/xylazine induced bradycardia in 10 of the 11 ferrets, (p = 0.0001). In yohimbine treated ferrets, an increase in mean heart rate measurement was noted 5 minutes after the intramuscular administration of yohimbine, and followed, over the next 15 minutes, by a progressive increase in mean heart rate. However, a corresponding decrease in mean heart rate measurement was observed in saline treated controls. Fifteen minutes after the injection of yohimbine, the mean heart rate measurement of yohimbine treated animals had increased to 194 beats per minute. This mean heart rate measurement is nearly 30% greater than the mean heart rate of 150 beats per minute measured at 15 minutes post-saline injection in saline treated controls. Also, yohimbine treatment significantly reduced duration of recumbency in 10 of 11 ferrets (p = 0.0001). Mean duration of recumbency for yohimbine treated ferrets was 41 +/- 9.7 minutes, whereas mean duration of recumbency for saline treated ferrets was determined to be 80 +/- 11.4 minutes.(ABSTRACT TRUNCATED AT 250 WORDS)
Automatic Sizing Functions for 3D Unstructured Mesh Generation (2017)

We present a novel algorithm to automatically create high-quality sizing functions for unstructured volume mesh generation. Firstly, appropriate techniques are proposed to create a tetrahedral background mesh, in which an initial sizing function is defined by considering geometrical factors and user-specified parameters. Then, a convex nonlinear programming problem is formulated and solved efficiently to obtain a smoothed sizing function. This function corresponds to a mesh satisfying necessary gradient constraint conditions and containing reduced number of elements. Finally, the smoothed sizing function is used by an advancing front surface mesher and a Delaunay tetrahedralization based volume mesher. With the aid of a walk-through algorithm, efficient sizing-value query schemes are developed. Various meshing experiments are presented to demonstrate that the proposed approach enables an accurate and fully automatic unstructured mesh generation pipeline.

Production of palatinose using Serratia plymuthica cells immobilized in chitosan (2003)

In recent decades, the production of palatinose has aroused great interest since this structural isomer of sucrose has interesting potential. We describe a simple and effective method of immobilizing Serratia plymuthica cells in chitosan. The sucrose isomerase activity of immobilized preparations was enhanced many times by activation with fresh nutrient medium and subsequent drying. The preparations obtained were physically very stable with high enzyme activity and excellent operational stability. The effect of temperature, pH and substrate concentration on enzyme activity of the immobilized cells was investigated. Using immobilized cells, a complete conversion of sucrose (40% solution) into palatinose was achieved in 4 h in a "batch"-type enzyme reactor. The use of free or immobilized cells had no effect on the composition of the solution, in particular the sugar content. The palatinose content was 80% and that of trehalulose 7%.
Identification of the Transgenic Integration Site in Immunodeficient tgε26 Human CD3ε Transgenic Mice (2010)

A strain of human CD3ε transgenic mice, tgε26, exhibits severe immunodeficiency associated with early arrest of T cell development. Complete loss of T cells is observed in homozygous tgε26 mice, but not in heterozygotes, suggesting that genomic disruption due to transgenic integration may contribute to the arrest of T cell development. Here we report the identification of the transgenic integration site in tgε26 mice. We found that multiple copies of the human CD3ε transgene are inserted between the Sstr5 and Metrn loci on chromosome 17, and that this is accompanied by duplication of the neighboring genomic region spanning 323 kb. However, none of the genes in this region were abrogated. These results suggest that the severe immunodeficiency seen in tgε26 mice is not due to gene disruption resulting from transgenic integration.

Overexpression of <i>zmm28</i> increases maize grain yield in the field (2019)

Increasing maize grain yield has been a major focus of both plant breeding and genetic engineering to meet the global demand for food, feed, and industrial uses. We report that increasing and extending expression of a maize MADS-box transcription factor gene, <i>zmm28</i>, under the control of a moderate-constitutive maize promoter, results in maize plants with increased plant growth, photosynthesis capacity, and nitrogen utilization. Molecular and biochemical characterization of <i>zmm28</i> transgenic plants demonstrated that their enhanced agronomic traits are associated with elevated plant carbon assimilation, nitrogen utilization, and plant growth. Overall, these positive attributes are associated with a significant increase in grain yield relative to wild-type controls that is consistent across years, environments, and elite germplasm backgrounds.

Functionalization of SBA-15 materials for the adsorption of phenols from aqueous solution (2012)

Abstract Water pollution by toxic organic compounds is a problem and demand for efficient adsorbents for the removal of toxic compounds is increasing. In the present work, we studied the functionalization of SBA-15 materials via the co-condensation between an alkoxysilane and an organoalkoxysilane in the presence of P123 as structuring agent. Several types of ligands were used: 3-mercaptopropylmethyldimethoxysilane, N-[3-(trimethoxysilyl) propyl] aniline; aminopropyltrimethoxysilane; [aminoethylamino]-propyltrimethoxysilanes and [(2-aminoethylamino) ethylamino] propyltrimethoxysilanes. These materials exhibit BET surface area of 275–776 m2/g and total pore volume of 0.29–1 cm3/g, depending on the ligand types and contents. Elementary analysis results confirm the incorporation of both thiol and amine group in the materials. Batch adsorption studies shows that the adsorption capacity of phenol drifts on the amine and thiol functionalized SBA-15 is greater than that on pure SBA-15. A linear relationship was observed between the adsorption capacity and N/SiO2 ratio. It was shown that the presence of amine promotes interactions with water molecules, on the other hand, these results can also be explained by the basic behavior of N-functionalized materials.
Maximum Pipelining of Array Operations on Static Data Flow Machine. (1983)

Data flow computers are a radical departure from conventional computer architecture, and new methodologies are required for generating efficient machine-level programs from high level user programming languages. The authors show that, for certain programs in the VAL language, it is possible to construct machine-level data flow programs that support fully pipelined computation. A VAL program in the class considered consists of blocks of code each of which defines a new array value either by a forall expression in which each element may be computed independently, or by a for-iter expression that defines array elements by a first-order recurrence relation. 7 references.
An efficient curvature‐based partitioning of large‐scale STL models (2011)

Purpose Rapid prototyping (RP) of large‐scale solid models requires the stereolithographic (STL) file to be precisely partitioned. Especially, the selection of cutting positions is critical for the fabrication and assembly of sub‐models. The purpose of this paper is to present an efficient curvature‐based partitioning for selecting the best‐fit loop and decomposing the large complex model into smaller and simpler sub‐models with similar‐shaped joints, which facilitate the final assembly. Design/methodology/approach The partition algorithm is benefited from curvature analysis of the model surface, including extracting the feature edges and constructing the feature loops. The efficiency enhancement is achieved by selecting the best‐fit loop and constructing the similar‐shape joints. The utility of the algorithm is demonstrated by the fabrication of large‐scale rapid prototypes. Findings By using the proposed curvature‐based partition algorithm, the reasonability and efficiency of STL model partition can be greatly improved, and the complexity of sub‐models has been reduced. It is found that the large‐scale model is efficiently partitioned and the sub‐models are precisely assembled using the proposed partitioning. Originality/value The curvature‐based partition algorithm is used in the RP field for the first time. Based on the curvature‐based partitioning, the reasonability and efficiency of large‐scale RP is addressed in this paper.
THE EFFECT OF FRUSEMIDE, MEXILETINE, (+)‐PROPRANOLOL AND THREE BENZODIAZEPINE DRUGS ON INTERICTAL SPIKE DISCHARGES IN THE ELECTROENCEPHALOGRAMS OF EPILEPTIC PATIENTS (1977)

The effects of single intravenous doses of diazepam, clonazepam, lorazepam, frusemide, mexiletine and (+)‐propranolol on the frequency of electroencephalographic (EEG) interictal spike discharges were assessed in three double‐blind placebo‐controlled trials in fourteen epileptic patients. Diazepam (5 mg) produced a significant mean decrease of spike discharges to about one third of the control frequency. The effect developed rapidly and persisted for the duration of the study (up to 25 min after injection). A larger dose (10 mg) failed to produce a further reduction in the frequency of the spike discharges. Clonazepam (0.5 mg), frusemide (40 mg) and lorazepam (2 mg) appeared to be as effective as diazepam in reducing spike discharges, although the effect of the latter drug seemed to develop with some delay. Mexiletine (100 mg) and (+)‐propranolol (50 mg) did not reduce paroxysmal EEG discharges, their effects being not significantly different from that of saline. EEG spike counting after intravenous administration of single test‐doses appeared to be both a simple and promising technique for the rapid preliminary evaluation of the clinical efficacy of new anti‐epileptic drugs.

Cytomorphological grading and feulgen DNA-analysis of metaplastic and neoplastic bronchial cells (1978)

Quantitative determinations of nuclear DNA were made on squamous metaplastic and neoplastic cells from sputum cytology specimens. The cellular material was processed by destaining diagnostic smears, restaining by the Feulgen method and relocating the cells for measurement. Adventitious leucocytes were used as internal controls. There was good correlation between increasing degree of aneuploidy as judged from DNA values, and increasing degree of morphologic nuclear atypia. The data indicate a progressive aberration from normality of nuclear DNA content in squamous metaplastic and neoplastic cells exhibiting a progressive degree of atypia. This implies that squamous bronchial carcinoma is preceded by sequential changes of the cellular composition which may be recorded by both quantitative DNA analysis and cytology.
Simultaneous Determination of Different Antibiotic Residues in Bovine and in Porcine Kidneys by Solid-Phase Fluorescence Immunoassay (2003)

Parallux, a solid-phase fluorescence immunoassay (SPFIA) developed for antibiotic residue detection in milk, was used for analysis of bovine and porcine kidney tissue. Four tetracyclines, 2 broad-spectrum cephalosporins, 3 beta-lactam antibiotics, and cephapirin were detected in one run after minimal sample preparation. This commercially available test system is designed as cartridges, each with a combination of 1-4 tests. One cartridge can be used to detect 4 analytes in the same sample, or 1 or 2 analytes in different samples. The cartridge with the combination tetracyclines-ceftiofur-penicillin-cephapirin was selected because tetracyclines, beta-lactam antibiotics as well as cephalosporins, are registered for oral or parenteral use in bovines and pigs in Europe. The test is qualitative and is recommended only for screening. Tetracycline, oxytetracycline, chlortetracycline, and doxycycline were easily detected at 300 ppb with the tetracyclines channel; ceftiofur at 1000 ppb and cefquinome at 200 ppb with the ceftiofur channel; penicillin G, ampicillin, and amoxicillin at 50 ppb with the penicillin channel; and cephapirin at 100 ppb with the cephapirin channel. These levels are equal to or lower than the corresponding maximal residue limits in kidney tissue. Cephalexin was not detected. The SPFIA test can be used as an alternative to classical inhibition tests and for post-screening inhibitor- positive kidneys, because it detects 3 specific groups of antibiotics, which enables selection of specific confirmatory methods for identification and quantification.
