Productivity: A Review For The Hospitality Manager

Hospitality managers have a number of methods available to them to enhance employee productivity. The author discusses five major concepts that can lead to successful results in the hospitality industry

Capital Punishment: Constitutional Parameters for the Ultimate Penalty

Four years after Furmanv. Georgia, the Supreme Court has resolved the major question left unanswered by that decision - does capital punishment per se constitute cruel and unusual punishment in violation of the eighth amendment? The Court also announced the statutory standards which satisfy Furman\u27s requirement that the death penalty not be imposed arbitrarily or capriciously. By a 7-2 vote, the Court held that the imposition of the death penalty for murder did not per se constitute cruel and unusual punishment. By the same vote, the Court upheld the capital sentencing statutes of Georgia, Florida and Texas, noting that arbitrary and capricious infliction of the death penalty can be avoided by a carefully drafted statute that ensures that the sentencing authority is given adequate information and guidance. By a 5-4vote, the Court invalidated North Carolina\u27s and Louisiana\u27s mandatory death penalty statutes, holding that the eighth amendment required consideration of individual characteristics of the offender and the circumstances of the offense. These decisions also have had the effect of invalidating statutes imposing a mandatory death penalty, including Virginia\u27s current capital punishment statute which was held unconstitutional by the Circuit Court of Loudoun County on October 14, 1976

Data on the Validation to Determine the Material Thermal Properties Estimation Via a One-Dimensional Transient Convection Model

These data were acquired to estimate the parameters of a closed form solution of a one-dimensional transient convection heat diffusion PDE. The purpose was to demonstrate that the model could be used to determine the thermal conductivity. The system was tested for a wide range of thermal conductivity, 15-400 W/mK, in order to verify that the method was applicable for various materials. The data reported here refer to the study in the research articles, Material Thermal Properties Estimation Via a One-Dimensional Transient Convection Model [1] and Influence of porosity on the thermal, electrical, and mechanical performance of selective laser melted stainless steel [2]. The dataset contains the raw data obtained from the temperature acquisition system as well as the processed results from a Python program to determine the thermal conductivity from a forced convection, transient one-dimensional heat diffusion equation

Design, Optimization, and the Prototyping of a Small Tuning-Fork Ultrasonic Piezoelectric Linear Motor

The design, optimization, and properties of a prototype small traveling-wave ultrasonic piezoelectric linear motor design are described. A method for optimizing the geometry of the motor to maximize its mechanical output for a given electrical input is described, as is the inherent properties of the design to maximize the motors durability and utilization of the piezoelectric material. Results from testing the motor demonstrate the design and indicate a maximum speed of 2.5 cm/s with a preload of 16 g due to an applied voltage of 80 V/RMS/ at an applied current of 15 mA

Chemical modulation of alveolar epithelial permeability.

The volume and composition of fluid on the surface of the alveoli can affect alveolar ventilation, gas diffusion, and macrophage function. The passive permeability and active processes of the alveolar epithelial lining play a role in regulating surface fluid and are a potential site of damage by airborne chemicals. Like other epithelial barriers, the alveolar lining is permeable to lipophilic substances but restricts the transmural flow of small ions and hydrophilic nonelectrolytes (equivalent pore radius ca. 0.5-1.5 nm). The mammalian fetal lung and alveolar sacs of the adult bullfrog secrete Cl- and K+ into the airspace. Secretion by the fetal lung ceases at birth. Many environmental agents increase the permeability of the capillary endothelium and/or respiratory epithelium and induce pulmonary edema. Studies with bullfrog alveolar sacs have demonstrated that selective effects may or may not be followed by general derangement of the epithelial barrier. Exposure of the luminal surface to HgCl2 (10(-6) to 10(-4) M) induces a selective increase in Cl- secretion that is followed by a fall in transport and a general increase in ion permeation. CdCl2 (10(-5) to 10(-3) M) depresses ciliomotion on cells on the trabecula of the alveolus but does not affect Cl- secretion or transepithelial conductance. HNO3, like other mineral acids, increases conductance and the radii or pores in the barrier, whereas NaNO3 selectively inhibits Cl- secretion. Amphotericin B(10(7) to 10(-5) MJ) induces K+ secretion into the lumen of both bullfrog and rat lung. We conclude that environmental agents induce changes in epithelial function that may compromise the lung's ability to regulate respiratory fluid without destroying the characteristic permeability of the epithelial lining
