Influence of Temperature on Ion Adsorption by Hydrous Metal Oxides (1990)

Adsorption processes are most often studied and modeled at room temperatures. At other temperatures, however, several factors act to perturb adsorption phenomena. These include shifts in equilibria among solution species, changes in the zero point of charge (pHzpc) of the sorbent, and changes in the ratio of adsorbed to solution phase ions. Fortunately, the magnitude of these factors can be predicted with standard thermodynamic relationships if solution and adsorption enthalpy data are available. Comparative adsorption studies at several temperatures, and calorimetry can be used to obtain adsorption enthalpies. Relatively few studies have been performed but these do suggest several general trends apply. First, the pHzpc of hydrous metal oxides appear to decrease with increasing temperature and consequently, proton adsorption enthalpies are exothermic. Typical values at the pHzpc are -20 to -45 kJ/mole which corresponds to pHzpc changes of less than ±0.5 pH units for 25 ±20°C. Second, anion adsorption decreases with increasing temperature while metal cation adsorption increases and as a result, anion adsorption is exothermic and metal cation adsorption endothermic. Available data suggest adsorption enthalpies are often ±20 kJ/mole or greater. This implies 20°C temperature gradients, which are rather common in temperate climates, could more than double or halve the adsorbed to solution ratio of a particular ion. Thus, temperature should be considered an important variable when investigating or modeling adsorption processes.

A Finger-Ring ShapedWearable HANDset based on Bone-Conduction (2005)

This paper introduces a finger-ring shaped wearable HANDset. It uses the human finger as a transmission route for the receiving voice (bone conduction). Vibration noise is reduced using a newly-created microphone unit named "Duaphragm" that can suppress echo by about 70%. Duaphragm provides a small, low-power, and low-cost means of reducing vibration noise. In addition, a new LSI chip that integrates an accelerometer and a tapping command detector allows the handset to be controlled by tapping the fingertip on which the device is worn. Keywords: interface device, headset, noise cancel.
Differential regulation of rat glomerular and proximal tubular renin mRNA following uninephrectomy (1996)

Angiotensin II is thought to play a role in the renal adaptations to reduced renal mass, but earlier work has shown that plasma renin activity (PRA) does not increase in this setting. To examine this paradox, we studied the effect of uninephrectomy (UNX) on circulating, juxtaglomerular, glomerular, and proximal tubular (PT) renin. PRA was unchanged 2 wk following UNX and fell slightly at 6 wk. Single kidney renin secretory capacity and cortical renin mRNA, reflecting juxtaglomerular renin, were unchanged at 2 and 6 wk. With quantitative competitive reverse transcription-polymerase chain reaction, renin mRNA in microdissected glomeruli and PT were dramatically increased 2 wk post-UNIX (for glomeruli: sham, 1.2 +/- 0.3, vs. UNX, 8.8 +/- 1.9 x 10(5) copies/glomerulus; for PT: sham, 4.6 +/- 0.9, vs. UNX, 17.7 +/- 5.1 x 10(3) copies/mm). By 6 wk, glomerular renin was unchanged, and PT renin mRNA was markedly suppressed (for glomeruli; sham, 2.9 +/- 1.2, vs. UNX, 4.2 +/- 1.1 x 10(5) copies/glomerulus; for PT: sham, 7.5 +/- 2.1, vs. UNX, 1.0 +/- 0.3 x 10(3) copies/mm). These results demonstrate differential regulation of the circulating, juxtaglomerular, glomerular, and PT renin systems. Early activation of glomerular and PT renin may result in increased local generation of angiotensin II and thereby affect renal structural and functional adaptations following UNX.
A programmable implantable micro-stimulator SoC with wireless telemetry: Application in closed-loop endocardial stimulation for cardiac pacemaker (2011)

The use of closed-loop implantable telemetry devices is increasing as recent clinical studies have shown their efficiency and usefulness in detecting and treating various cardiac arrhythmias. In this paper, we present a single-chip closed-loop system providing closed-loop feedback of sensed cardiac patterns. This device promises more optimized stimulation parameters to cure rapid arrhythmias compared with open-loop devices. Our system incorporates more functionality comparing with the conventional micro-stimulators, yet consumes less power. It is powered by implanted rechargeable batteries periodically charged by radio-frequency (RF) coupling. This improvement of the powering system can prevent improper device operation or shutdown due to RF coupling and loading variations. Furthermore, this system eliminates the need for periodic surgery for battery replacement and improves quality of life of the patient. In this work, an implantable micro-stimulator SoC (IMSoC) is designed as cardiac defibrillator for remote delivery of power by means of coupled coils supplying power to a bio-implanted rechargeable battery. The IMSoC consists of a smart control circuit for power management, an RF-coupling power system for battery charging and 2 ultra-small rechargeable batteries as power supplies. The micro-stimulator circuit embedded in the IMSoC is externally powered and controlled by a single encoded RF carrier. Stimulus parameters, such as pulse width, amplitude, and frequency, can be programmed from the remote controller.
Mechanisms for HIV Tat upregulation of IL‐10 and other cytokine expression: Kinase signaling and PKR‐mediated immune response (2005)

HIV Tat has been known to have multiple regulatory roles including replication of HIV and modulation of cellular kinases. We investigated whether signaling kinase PKR plays a critical role in mediating Tat-induced cytokine dysregulation. We showed Tat induction of IL-10 dysregulation is associated with PKR activation. To examine the mechanism involved, inhibition of PKR activity abrogated the Tat-induced cytokine induction. We next identified that the MAP kinases including ERK-1/2 and p38 are downstream of PKR in these Tat-induced pathways. Thus, PKR may play a critical role in mediating the subversive effects of HIV Tat resulting in IL-10 induction.
Microwave- or Microreactor-Assisted Conversion of Furfuryl Alcohols into 4-Hydroxy-2-cyclopentenones (2010)

The conversion of a variety of furfuryl alcohols, derived from renewable non edible resources such as bran, into 4-hydroxy-2-cyclopentenones was accomplished using microwave irradiation. In subcritical water (220 ˚C, 15.5 bar) without the need for any catalyst the reaction proceeds approximately two orders of magnitude faster with up to twice the yield compared to methods previously reported that apply conventional heating techniques. For the parent furfuryl alcohol the process could be transferred to a microreactor, allowing the synthesis of 4-hydroxy-2-cyclopentenone in a continuous flow system on multigram scale.
Anular Incision Technique on the Strength and Multidirectional Flexibility of the Healing Intervertebral Disc (1994)

The technique of anular incision plays a definite role in the timing and strength of subsequent anular healing. The box incision through the anulus led to significantly weaker healing than did the slit incision in the early healing phase (2-4 weeks). Also, larger amounts of motion were seen in the vertebral motion segments of those discs undergoing box incision when compared with slit or control levels.
THE STUDY OF MEDICAL STUDENTS' SATISFACTION WITH ACTIVE PARTICIPATION IN THE PRESENTATION OF THE TOPIC OF POISONING (2014)

Background: Failure in reaching the predetermined goals of education can be considered as one of the most important problems of educational systems. Today, it is believed that active teaching methods are more effective than lecturing which lead to effective teaching. Participation of students in education is one of the major factors of active learning. The purpose of the present study is to determine student satisfaction with active participation (through seminar giving) in the case of teaching the topic of poisonings. Methods: This analytical descriptive study was conducted on all stage students of Birjand University of Medical Sciences who had selected the course of familiarity with poisoning and forensic medicine. The technical part of this topic was taught by students through seminar. For the evaluation of the satisfaction of students a questionnaire was used. Data was analyzed by SPSS 16; Pearson Correlation Test, and Independent T-test and meaningful level was considered as p≤0.05. Results: forty students participated in this study. The mean of satisfaction score of students with active teaching method through seminar was 31.47 (out of maximum 50).The mean of satisfaction score in each one of the fields was meaningfully related with the total average students. The mean score of females in the field of internal interest and motivation was meaningfully more than males. Conclusion: The results of this study showed that students were satisfied with the participation in the process of teaching .Factors such as total average of students and their gender had affected their score which must be taken in to consideration in curriculum planning.
Homodyne OFDM with Optical Injection Locking for Carrier Recovery (2014)

Homodyne detection provides the simplest digital signal processing (DSP) solution to optical coherent detection and minimizes the receiver bandwidth requirements. These features make it promising for high spectrally efficient formats such as optical orthogonal frequency domain multiplexing (OFDM), which has a flat optical spectrum and which is thus inherently sensitive to high-frequency distortions, e.g., due to limited detector bandwidth. The key to homodyne detection is recovery of the carrier from the received signal all optically (as opposed to frequency offset compensation via DSP. Herein, we use optical injection locking (OIL) in conjunction with carrier tone-assisted OFDM to achieve this. In contrast to previous reports, we show that OIL carrier recovery with subsequent homodyne detection can operate without the need for any optical prefiltering. First, we evaluate the performance as a function of the carrier tone guardband bandwidth. Further, we improve the robustness of this technique using a slow-phase lock loop that compensates for drift in the laser's temperature/current control electronics. Using this improved setup, we compare our all-optical-carrier-recovered homodyne and the “traditional” DSP-assisted intradyne detection for the case of OFDM-16QAM signals. Finally, we compare the computing complexity necessary for both approaches and estimate the intradyne performance limitations due to the carrier-local oscillator frequency offset.

Go-ICP: A Globally Optimal Solution to 3D ICP Point-Set Registration (2015)

The Iterative Closest Point (ICP) algorithm is one of the most widely used methods for point-set registration. However, being based on local iterative optimization, ICP is known to be susceptible to local minima. Its performance critically relies on the quality of the initialization and only local optimality is guaranteed. This paper presents the first globally optimal algorithm, named Go-ICP, for Euclidean (rigid) registration of two 3D point-sets under the L<sub>2</sub> error metric defined in ICP. The Go-ICP method is based on a branch-and-bound scheme that searches the entire 3D motion space SE(3). By exploiting the special structure of SE(3) geometry, we derive novel upper and lower bounds for the registration error function. Local ICP is integrated into the BnB scheme, which speeds up the new method while guaranteeing global optimality. We also discuss extensions, addressing the issue of outlier robustness. The evaluation demonstrates that the proposed method is able to produce reliable registration results regardless of the initialization. Go-ICP can be applied in scenarios where an optimal solution is desirable or where a good initialization is not always available.
In vitro study of the antibiotic activity of diterpenes. (1987)

The antibiotic activity of 16 diterpenes and of 2 phenanthrene derivatives of diterpene origin, isolated from Brazilian plants was investigated against bacteria, yeasts, dermatophytes and aflatoxin-producing fungi. Eight of the compounds were completely inactive. None showed inhibitory activity against the Gram-negative bacteria assayed or against the Aspergillus species. The phenanthrene derivatives, chemically very similar to phytoalexins isolated from orchids, were especially active.
Web site personalization based on link analysis and navigational patterns (2007)

The continuous growth in the size and use of the World Wide Web imposes new methods of design and development of online information services. The need for predicting the users' needs in order to improve the usability and user retention of a Web site is more than evident and can be addressed by personalizing it. Recommendation algorithms aim at proposing “next” pages to users based on their current visit and past users' navigational patterns. In the vast majority of related algorithms, however, only the usage data is used to produce recommendations, disregarding the structural properties of the Web graph. Thus important—in terms of PageRank authority score—pages may be underrated. In this work, we present UPR , a PageRank-style algorithm which combines usage data and link analysis techniques for assigning probabilities to Web pages based on their importance in the Web site's navigational graph. We propose the application of a localized version of UPR ( l-UPR ) to personalized navigational subgraphs for online Web page ranking and recommendation. Moreover, we propose a hybrid probabilistic predictive model based on Markov models and link analysis for assigning prior probabilities in a hybrid probabilistic model. We prove, through experimentation, that this approach results in more objective and representative predictions than the ones produced from the pure usage-based approaches.
A unique residue in rab3c determines the interaction with novel binding protein Zwint‐1 (2008)

Exocytic events are tightly regulated cellular processes in which rab GTPases and their interacting proteins perform an important function. We set out to identify new binding partners of rab3, which mediates regulated secretion events in specialized cells. We discovered Zwint-1 as a rab3 specific binding protein that bound preferentially to rab3c. The interaction depends on a critical residue in rab3c that determines the binding efficiency of Zwint-1, which is immaterial for interaction with rabphilin3a. Rab3c and Zwint-1 are expressed highly in brain and colocalized extensively in primary hippocampal neurons. We also found that SNAP25 bound to the same region in Zwint-1 as rab3c, suggesting a new role for the kinetochore protein Zwint-1 in presynaptic events that are regulated by rab3 and SNAP25.
Transient receptor potential A1 mediates gastric distention-induced visceral pain in rats (2009)

Monosize microbeads based on polystyrene and their modified forms for some selected medical and biological applications (1994)

Polymeric particles are produced by different polymerization techniques. Phase inversion (dispersion) polymerization is one of the recent techniques to obtain monosize polymeric microbeads in the size range of 1-50 microns. The size and monodispersity of these microbeads can be adjusted by using several solvent systems (e.g., alcohol-water mixtures) with different polarities and by changing the type and amount of monomer, initiator and stabilizer. Surfaces of these microbeads can be further modified by different techniques including coating with different copolymers. Monosize polymeric microbeads are widely used in medical and biological applications as carriers, such as in immunoassays and cell separation, in site-specific drug delivery systems, in nuclear medicine for diagnostic imaging, in studying the phagocytic process, in affinity separation of biological entities, etc. Here, some important aspects of the production of monosize microbeads based on polystyrene and their modified forms are briefly discussed, and some selected medical and biological applications are summarized.
Acoustic Velocities in Petroleum Oils (1988)

ABSTRACT A series of experiments were carried out in the laboratory on acoustic wave velocities in oils. The samples include 8 dead crude oils (here dead oil refers to stock tank oil which does not contain dissolved gas), 2 refined petroleum hydrocarbons, and 1 live oil (here live oil refers to oil which has high content of dissolved gas). The results show that the measured acoustic velocities in these oils are strong functions of both temperature and pressure. The experimental results are discussed in light of the various existing theories and models of the liquid state for the purpose of interpreting and understanding the acoustic velocity behaviors of the oils. Correlations are made between the acoustic velocity and temperature, pressure, API gravity, and molecular weight. Empirical equations are established which can be used to calculate the acoustic velocities in oils with known API gravities. Various applications or potential applications of the experimental results are also discussed.
The Development of Two Simple Tire Warning Devices (1984)

This paper describes two types of tire pressure warning devices, TWD-I and TWD-II, that are low in cost and are easy to install on a vehicle. TWD-I has a buzzer and a dry-cell battery that are attached on the inside of the wheel center cap. They are connected to a pressure switch that is attached to the air valve stem after the tire is filled with air to the prescribed pressure. If the pressure drops below a certain level, the switch sends a signal that energizes buzzer. TWD-II is a kind of monitor that indicates a drop in tire pressure by changing the color of the wheel center cap through the action of a diaphragm and a magnet. In comparison with conventional innovations, the two new warning devices offer the advantages of lower cost and easier installation on vehicle.
