A short review of green extraction technologies for rice bran oil (2020)

Abstract Rice is one of the most important crops throughout the world, as it contributes toward satisfying the food demand of much of the global population. It is well known that rice production generates a considerable number of by-products, among which rice bran deserves particular attention. This by-product is exceptionally rich in nutrients, since it contains a wide spectrum of macronutrients (proteins, fats, carbohydrates) as well as dietary fibers and bioactive compounds. However, rice bran is usually wasted or just used for the production of low-cost products. The lipidic fraction of rice bran contains an unsaponifiable fraction that is rich in such functional components as tocopherols, γ-oryzanol, tocotrienols, and phytosterols. This lipidic fraction can be extracted to obtain rice bran oil (RBO), a high value-added product with unique health properties as a result of its high concentration in γ-oryzanol, a powerful antioxidant mixture of bioactive molecules. Conventional extraction methods employ hexane as the solvent, but these methods suffer from some drawbacks linked to the toxicity of hexane for humans and the environment. The aim of the review presented herein is to point out the new green technologies currently applied for the extraction of RBO, by highlighting reliable alternatives to conventional solvent extraction methods that are in line with the twelve principles of green chemistry and a circular economy.
Effects of nonionizing prepulses in high-intensity laser-solid interactions (2001)

We present theoretical and experimental evidence that nonionizing prepulses with intensities as low as 10(8)-10(9) W/cm(2) can substantially alter high intensity laser-solid interactions. We show that prepulse-heating and vaporization of the target can lead to a preformed plasma once the vapor is ionized by the rising edge of the high-intensity pulse. Our results indicate that peak prepulse intensity is not the only important parameter to consider in determining preformed plasma thresholds, and that a more comprehensive analysis of the prepulse duration and the target material is required.

Synthesis and antibacterial activity of O-methylazithromycin derivatives. (1992)

A series of O-methylazithromycin derivatives have been synthesized and their antibacterial activities were compared with those of azithromycin (1). O-Methylation of 1 proceeded stepwise by the two main pathways beginning at the C-6 and C-11 hydroxyl groups, individually. Among O-methyl derivatives, 6-O-methylazithromycin A (11) was slightly less active than 1. The methylation of the secondary hydroxyl group at the C-11 position resulted surprisingly in an increase of their in vitro activity. The antibacterial activities of novel azalides decreased with increasing the number of the methyl groups introduced.
Geolocation of MIMO signals using the cross ambiguity function and TDOA/FDOA (2012)

The geolocation of RF signals has many civilian and military applications. One technique for geolocation involves using the cross ambiguity function (CAF) to calculate the time-difference-of-arrival (TDOA) and frequency-difference-of-arrival (FDOA) of the emitted signal using two receivers. Until recently most RF signals fell under the category of Single-Input-Single-Output (SISO). Now however, Multiple-Input-Multiple-Output (MIMO) technologies such as Wi-Fi's IEEE 802.11n are becoming more ubiquitous. The inherent use of multiple antennas in MIMO technologies has an effect on the geolocation of these signals. This paper therefore explores the effect of spatially multiplexed MIMO signals on the cross ambiguity function in regards to the calculation of TDOA and FDOA, and the resulting effect on geolocation.
Packet scheduling for Voice over IP over HSDPA in mixed traffic scenarios with different end-to-end delay budgets (2006)

By means of dynamic system-level simulations, this work evaluates whether the studied Packet Scheduling (PS) algorithms are capable of guaranteeing the quality of service (QoS) of the voice over IP (VoIP) on a scenario where the VoIP and Web browsing services will compete for the same resources and there is a maximum allowed end-to-end delay for VoIP packets. Two sets of algorithms were considered: QoS-differentiated and non-QoS-differentiated algorithms. It was verified the system capacity gains when the VoIP delay budget is increased. Regarding the PS performance, those algorithms able to perform QoS differentiation presented better performance in terms of system capacity and QoS compared to those non-QoS-differentiated algorithms. Among the former category, those that take into consideration delay requirements of the VoIP service presented the best overall capacity for all traffic mixes and delay budgets.
Weak Solutions in Elasticity of Dipolar Porous Materials (2008)

The main aim of our study is to use some general results from the general theory of elliptic equations in order to obtain some qualitative results in a concrete and very applicative situation. In fact, we will prove the existence and uniqueness of the generalized solutions for the boundary value problems in elasticity of initially stressed bodies with voids (porous materials).

A Tubular Directional Microphone (1939)

A tubular directional microphone is described which consists of a pressure type microphone coupled to an acoustic impedance element composed of a large number of tubes whose lengths vary by equal increments. The function of this variation in length is twofold. First, the multiple resonances of the individual tubes occur at intervals so close together that the net effect of the bundle is that of an acoustic resistance over a fairly wide frequency range and so does not impair the high quality of the attached microphone. Second, high directivity is secured, because for sound incidence other than normal each tube introduces a different path length with phase cancellation resulting in a composition chamber between the microphone and the ends of the tubes. The theory of operation is summarized and data are presented to show the performance of the instrument which is in fair agreement with the theory.
High temperature SAW gas sensor on langasite (2004)

Novel Surface Acoustic Wave (SAW) devices using the new langasite (LGS) family of crystals have been designed, fabricated, and tested for high temperature (up to 750/spl deg/C) gas sensor applications. The devices were fabricated using platinum (Pt) and palladium (Pd) thin film technology and were mounted in a high temperature sealed stainless steel chamber for gas testing. The high temperature SAW sensors have been exposed to temperatures from 250/spl deg/C to 750/spl deg/C and cycled more than ten times in that temperature range over periods from two to six weeks. Gas sensing of C/sub 2/H/sub 4/ in N/sub 2/ and H/sub 2/ in N/sub 2/ with baselines of O/sub 2/ and N/sub 2/ on the LGS SAW devices has been performed from 250/spl deg/C to 550/spl deg/C and is reported for the first time in this paper.
Regulation of the cell cycle by calcium and calmodulin (1993)

IN ORDER to reproduce and multiply, every cell must execute an orderly series of events, generally called the cell cycle, at some time during its life span. The cell cycle was first thought to consist of mitosis and interphase as determined from morphological analysis. As new techniques were developed, a period of DNA synthesis, the S phase, was detected; this was temporally separated from the previous mitosis by a “gap,” the G1 phase, and from the subsequent mitosis by another “gap,” the G2 phase (Fig. 1). The G1 phase is the decision phase in which cells either commit to undergo another round of DNA synthesis and continue to cycle or to exit the cell cycle to enter a quiescent state frequently referred to as G0. Cells in the G0 phase either terminally differentiate or resume proliferation upon addition of an appropriate mitogen (Fig. 1). When DNA synthesis is completed, cells normally proceed to mitosis. The regulation of this series of events is of primary interest to the endocrinologist, since precise control of cell fate is an essential element in hormone action. During the last decade, genetic analyses in fungi and biochemical studies in vertebrate and invertebrate species have resulted in identification of key regulatory proteins that specifically control progression through the decision points of the cell cycle. However, the overall process is very complicated, and control of cell proliferation is a result of a coordinated regulation of multiple biochemical pathways that integrate both intracellular and extracellular signals. Many critical components of these pathways remain to be elucidated.
Co-expression of laminin β3 and γ2 chains and epigenetic inactivation of laminin α3 chain in gastric cancer (2011)

Laminin-332 (LM-332, formerly termed laminin-5) is a heterotrimeric glycoprotein that regulates cell adhesion and migration. Molecular alterations of LM-332 are involved in cancer progression. The aim of this study was to clarify alterations of LM-332 in gastric carcinoma. The expression of LM-332 subunits in 10 gastric carcinoma cell lines was investigated by RT-PCR, Western blotting, and immuno-cytochemical/immunofluorescent analyses. The promoter methylation status of LM-332-encoding genes (LAMA3, LAMB3 and LAMC2) was analyzed by methylation-specific PCR (MSP). The relationship between cell migration and LM-332 expression was assessed by the scratch assay. The expression of LM-332 was analyzed immunohistochemically in 90 gastric cancer tissues. Co-expression of laminin β3 and γ2 chains was often observed in gastric carcinoma cell lines at mRNA and protein levels. In contrast, there was no expression of laminin α3 at either the mRNA or protein levels. Extra-cellular secretion of laminin β3 and γ2 chains was found in 2 of the 10 cell lines. The LAMA3 gene was transcriptionally silenced by methylation of the promoter CpG islands in all of the cell lines, while the LAMB3 and LAMC2 genes were silenced in several cell lines. Treatment with a demethylating agent, 5-aza-2'-deoxycytidine (5-aza-dC), restored expression of the LM-332-encoding genes. Methylation frequency of LAMA3 was higher than those of the LAMB2 and LAMC2 genes in gastric cancer tissues. Migration distances were significantly correlated with cytoplasmic laminin γ2 chain expression. Immunohistochemistry showed frequent co-expression of laminin β3 and γ2 chains in gastric carcinoma cells, which was significantly correlated with depth of invasion and advanced tumor stage. The results suggest that the laminin β3 and γ2 chains accumulate intracellularly and play a role in gastric cancer progression, while epigenetic silencing of the laminin α3 chain may lead to inability to synthesize the basement membrane and may affect cancer cell invasion. Cancer cell motility appears to be associated with the cyto-plasmic laminin γ2 chain in vitro.
Networks mediating the clinical effects of pallidal brain stimulation for Parkinson's disease: A PET study of resting-state glucose metabolism (2001)

Employing [(18)F]fluorodeoxyglucose (FDG) and PET, we have found previously that stereotaxic ablation of the internal globus pallidus (GPi) for Parkinson's disease causes resting metabolic changes in brain regions remote from the lesion site. In this study we determined whether similar metabolic changes occur in Parkinson's disease patients treated with deep brain stimulation (DBS) of the GPi. We studied seven Parkinson's disease patients with FDG-PET to measure resting regional cerebral glucose utilization on and off GPi stimulation. We used statistical parametric mapping to identify significant changes in regional brain metabolism that occurred with this intervention. We also quantified stimulation-related changes in the expression of a specific abnormal Parkinson's disease-related pattern of metabolic covariation (PDRP) that had been identified in earlier FDG-PET studies. Metabolic changes with DBS were correlated with clinical improvement as measured by changes in Unified Parkinson's Disease Rating Scale (UPDRS) motor ratings off medication. GPi DBS improved UPDRS motor ratings (36%, P < 0.001) and significantly increased regional glucose metabolism in the premotor cortex ipsilateral to stimulation and in the cerebellum bilaterally. GPi DBS also resulted in a significant (P < 0.01) decline in PDRP activity ipsilateral to stimulation, which correlated significantly with clinical improvement in UPDRS motor ratings (P < 0.03). Clinical improvement with GPi DBS is associated with reduced expression of an abnormal Parkinson's disease-related metabolic network involving elements of the cortico-striato-pallido-thalamocortical and the cerebello-cortical motor loops.

On maximizing the compound yield for 3D Wafer-to-Wafer stacked ICs (2010)

Three-Dimensional Stacked IC (3D-SIC) is an emerging technology that provides heterogeneous integration, higher performance, and lower power consumption compared to planar ICs. Fabricating these 3D-SICs using Wafer-to-Wafer (W2W) stacking has several advantages including: high throughput, thin wafer and small die handling, and high TSV density. However, W2W stacking suffers from low compound yield. This paper investigates various matching processes by using different wafer matching criteria in order to maximize the compound yield. It first establishes a framework covering different matching processes and wafer matching criteria for both replenished and non-replenished wafer repositories. Thereafter, a subset of the framework is analyzed. The simulation results show that the compound yield not only depends on the number of stacked dies, die yield, and repository size, but it also strongly depends on the used matching process and the wafer matching criteria. Moreover, by choosing an appropriate wafer matching scenario (e.g., wafer matching process, criterion etc.), the compound yield can be improved up to 13.4% relative to random W2W stacking.
Pulsed radio frequency energy (PRFE) use in human medical applications (2011)

A number of electromagnetic field-based technologies are available for therapeutic medical applications. These therapies can be broken down into different categories based on technical parameters employed and type of clinical application. Pulsed radio frequency energy (PRFE) therapy is a non invasive, electromagnetic field-based therapeutic that is based on delivery of pulsed, shortwave radio frequency energy in the 13-27.12 MHz carrier frequency range, and designed for local application to a target tissue without the intended generation of deep heat. It has been studied for use in a number of clinical applications, including as a palliative treatment for both postoperative and non postoperative pain and edema, as well as in wound healing applications. This review provides an introduction to the therapy, a summary of clinical efficacy studies using the therapy in specific applications, and an overview of treatment-related safety.
On-line diagnostic monitoring of photoresist ashing (1995)

On-line statistical process control (SPC) has been implemented on a single-wafer remote microwave plasma photoresist asher. SPC for ashing is made more difficult because the prior processes, e.g., ion implantation, affect the properties of the resist material, and consequently the ashing behavior. The system presented comprehends the variety of incoming wafer states from a complex process flow. On-line SPC charts track photoresist clear time on a wafer-to-wafer basis using optical emission spectroscopy. The data is corrected for the "first-wafer" effect, whereby the clear time for a wafer decreases as the delay time between ashing wafers increases. The data is standardized using an expected time and variance for each process flow level to allow all results to be presented in a single set of individuals and moving-standard deviation Shewhart charts. Standard SPC rules are applied automatically within each process flow level to test for unnatural variation in the data. Observed abnormal behavior is due mainly to changes in the incoming material for a specific process flow level, not deviations in the ashing process. When a shift in incoming wafer state is detected, the expected response for that process level is automatically updated to reflect the change. The usefulness of on-line monitoring as a means for identifying misprocessing at prior process steps has been demonstrated, Early diagnosis can save money by avoiding expensive downstream processing on previously misprocessed wafers, In our demonstration laboratory, the equipment has processed wafers from a dozen process flow levels.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
B- and T-cell prolymphocytic leukemia: antibody approaches. (2012)

B- and T-cell subtypes of prolymphocytic leukemia (PLL) are rare, aggressive lymphoid malignancies with characteristic morphologic, immunophenotypic, cytogenetic, and molecular features. Prognosis for these patients remains poor, with short survival times and no curative therapy. The advent of mAbs has improved treatment options. In B-PLL, rituximab-based combination chemoimmunotherapy is effective in fitter patients. TP53 abnormalities are common and, as for chronic lymphocytic leukemia, these patients should generally be managed using an alemtuzumab-based therapy. Currently, the best treatment for T-PLL is IV alemtuzumab, which has resulted in very high response rates of more than 90% when given as frontline treatment and a significant improvement in survival. Consolidation of remissions with autologous or allogeneic stem cell transplantation further prolongs survival times, and the latter may offer potential cure. The role of allogeneic transplantation with nonmyeloablative conditioning needs to be explored further in both T- and B-PLL to broaden the patient eligibility for what may be a curative treatment.
