Breaking the silence: three bHLH proteins direct cell‐fate decisions during stomatal development

Stomata are microscopic pores on the surface of land plants used for gas and water vapor exchange. A pair of highly specialized guard cells surround the pore and adjust pore size. Studies in Arabidopsis have revealed that cell-cell communication is essential to coordinate the asymmetric cell divisions required for proper stomatal patterning. Initial research in this area identified signaling molecules that negatively regulate stomatal differentiation. However, genes promoting cell-fate transition leading to mature guard cells remained elusive. Now, three closely related basic helix-loop-helix (bHLH) proteins, SPEECHLESS, MUTE and FAMA have been identified as positive regulators that direct three consecutive cell-fate decisions during stomatal development. The identification of these genes opens a new direction to investigate the evolution of stomatal development and the conserved functions of bHLH proteins in cell type differentiation adopted by plants and animals.

Rationalisation of First-Aid Measures for Elapid Snakebite

Summary The plasma of monkeys envenomated with tiger snake (Notechis scutatus) venom was monitored by radioimmunoassay for both crude venom and a neurotoxin. When the injected limb was immobilised and a pressure of 55 mm Hg applied to the injection site, only very low levels of circulating venom or neurotoxin were detectable. In practical terms, venom movement can be effectively delayed for long periods by the application of a firm crepe bandage to the length of the bitten limb combined with immobilisation by a splint. Pressure alone or immobilisation alone did not delay venom movement.

Analysis of the Influence of Energy Dissipative Under-Ride Guard's Parameters on Car-to-Truck Collision

Rear underrun crashes involving heavy vehicles have the most tragic consequences. This paper describes the concept of a special energy dissipative rear under-ride guard. A dynamic model of a car-to-truck collision was built where the truck had been equipped with such a guard. Simulation research of this model was made. The purpose of this study is to determine the influence of linear and non-linear characteristics of stiffness and damping on the collision course. Maximal value of the car deceleration during the collision was chosen as the major criterion of the bumper quality. The analyses confirm that the proposed bumper, in spite of the concept's simplicity, can be a very effective way of providing security during such a car-to-truck collision. (A)

Guarded burr for deepening of the nasofrontal junction.

Appropriate deepening of the nasofrontal junction remains one of the most difficult parts of rhinoplasty. A guarded burr is introduced that provides a safe and effective means of deepening or creating a shallow nasofrontal groove. The burr has a special guard that prevents the cutting of soft tissue. The guarded burr is introduced in position through the routine elevation of the bridge soft tissue subperiosteally. The safety latch is used for orientation. With gentle movement along the line connecting the canthi, the desired amount of bone can be removed from the nasofrontal junction with little time consumed. It is important to avoid continuous friction, since this might result in significant heat production and thereby thermal injury to the soft tissue and fluid collection.

A high frequency electronic transducer for multiphase flow measurements

This paper describes an electronic transducer for multiphase flow measurement. Its high sensitivity, good signal to noise ratio and accuracy are achieved through an electrical impedance sensor with a special guard technique. The transducer consists of a wide bandwidth and high slew rate differentiator where the lead inductance and stray capacitance effects are compensated. The sensor edge effect is eliminated by using a guard electrode based on the virtual ground potential of the operational amplifier. A theoretical modeling and a calibration method are also presented. The results obtained seem to confirm the validity of the proposed technique.

Irradiation tests of double-sided silicon strip detectors with a special guard ring structure

The results of the first irradiation tests of newly designed silicon microstrip detectors performed with 21 MeV protons at the Max-Planck-Institut in Heidelberg are presented. The detectors were developed and produced by the semiconductor laboratory of the Max-Planck-Institut in Munich. Novel guard ring structures allow operation of the detectors at voltages exceeding 300 V.

Guarded execution and branch prediction in dynamic ILP processors

We evaluate the effects of guarded (or conditional, or predicated) execution on the performance of an instruction level parallel processor employing dynamic branch prediction. First, we assess the utility of guarded execution, both qualitatively and quantitatively, using a variety of application programs. Our assessment shows that guarded execution significantly increases the opportunities, for both compiler and dynamic hardware, to extract and exploit parallelism. However, existing methods of specifying guarded execution have several drawbacks that limit its use. Second, we study the interaction of guarded execution and dynamic branch prediction and show that the use of guarded execution significantly increases the number of instructions between mispredicted branches. Third, we propose a new method of specifying guarded execution. The proposed method uses special GUARD instructions, which can be used to incorporate guarded execution into existing instruction sets. GUARD instructions realize the full power of guarded execution, without the drawbacks of existing methods of specifying guarded execution.

Russian Army Chaplains During World War I

For the tsarist state the activity of military chaplains served as a channel for the religious education of soldiers in the Russian army.1 Until the end of the eighteenth century chaplains were not segregated from those who served dioceses, and their allegiance to a diocese depended upon the location of their military unit. In time of war when armies were on the move, especially when they were on campaigns abroad, field supervisors were appointed from among the priests to supervise the regimental chaplains. On April 4, 1800, by decree of Paul I, a special administration for chaplains, headed by a field supervisory chaplain, was first established in the Russian army. In 1830 the posts of supervisory chaplain for headquarters and for the Special Guards' corps were instituted. Overall leadership of the military chaplains was the responsibility of the head chaplain of the guard unit and the grenadier of the army and the navy.2

On-line extraction of polymers, oligomers, additives and monomers by multiple solvents on packed HPLC columns

Extraction of monomers, additives, oligomers, and polymers from a blend is very time consuming and labor intensive. Now by use of a special guard column and multi-solvent gradient liquid chromatograph (HPLC), the extraction and analysis can be performed in one step.

A study of contamination and damage on Si surfaces induced by dry etching

Damage/contamination effects of dry etching in two different modes, plasma etching (PE) and reactive ion etching (RIE), on silicon surfaces just after oxide etching are discussed. The electrical measurements on aluminium Schottky diodes were used to evaluate the effect of dry processing and various postetch treatments on a Si substrate. The presence of heavy metal contamination of the Si surface as a result of dry etching was confirmed by secondary ion mass spectroscopy and SECCO etch defect decoration. C-t (minority-carrier lifetime) measurements on special guard ring devices were used as indirect evidence of heavy metal contaminants. The quality of a gate oxide grown on Si surfaces after dry-etching conditions was examined through breakdown voltage. Improved device electron mobility was observed for the RIE-exposed Si surface compared to PE, due to the smoother surface after the RIE process. >

An Analysis of Shielding Efficiency for 14C Counters

The “shielding” efficiency of the guard counters has been a main scope of the present investigation. Our special guard counters consist of closed shells (ca 3cm thick) filled with propane at 1.2 atmospheres pressure. These guard counters are nearly 100 percent efficient against charged particles, and 1 to 2 percent against gamma and neutrons. The efficiency has now been studied more in detail in an arrangement with four guard shells around a 14C counter. For each extra guard shell, the cosmic fraction of the counter background was reduced by ca 13 percent. The reduction does not involve penetrating high energy charged particles, but is related to γ ray showers penetrating the guards. A thicker old lead shield between 14C counter and the guard counters also reduces the background and serves the same purpose. In order to approach underground conditions for the 1.5 liter counter background (0.32 ± 0.01 c/min), most of the shielding material has to be put inside guard shells. An ordinary guard counter combined with an extra guard on top of the iron shield is very efficient. A background of 0.48 ± 0.01 c/min has already been obtained.
