A computer program for the multi-index analysis of thermal stress, COLDHOT, is presented. The program was developed in the Department of Architecture, Ahmadu Bello University, Zaria, Nigeria, as a design aid for students in building climatology. It uses basic climatic data to produce a graph of the thermal stress for every fifteen minutes of the day using any or all of several thermal indices. The degree of thermal stress in percentages on a bi-monthly basis is determined and a comparative summary for all indices used produced. The program is interactive and uncumbersome while the results are printed in a standard report format. Plots of the thermal stress in variable formats are also made on request.

A microcomputer program for time series forecasting has been developed in GW-BASIC for Zenith 150 microcomputers. The program uses such forecasting methods as: 1. single exponential smoothing, 2. adaptive-response-rate single exponential smoothing, and 3. Brown's double exponential smoothing. These methods are used to forecast the future values of a given time series. The program generates plots of the original time series and forecasted series as well as forecasting errors. It computes 90% and 95% confidence intervals for forecasted values and calculates such statistics as: 1. mean squared error, 2. mean absolute percentage error, 3. mean absolute error, 4. Durbin-Watson statistic, and 5. Theil's U statistic. Example problems illustrate the use of the program. The program includes a top-level menu displaying basic options, including: 1. a data entry option used to create time series of up to 200 periods, 2. editing and modifying existing time series, 3. obtaining a printout of observations in a time series, and 4. viewing a plot of a given time series.

The probit function is widely used to model a logistic relationship between a stimulus and a quantal response in toxicology and biology. The probit function may be appropriate for modeling other systems showing sigmoid relationships. The objective of this paper is to provide an additional means for determining two factor log-probit analysis. The BASIC programs presented here were developed using the probit equation and the tables published by C. I. Bliss and D. J. Finny. These programs can be used as presented or adapted as subroutines within other application programs. Refs.

A computer program which expedites the quantitation and comparison of cultured lymphocyte proliferative responses is described. The program, entitled PROLIF, is written in VAX BASIC and computes this in vitro activity by collating and reducing radioactive count data obtained from tritiated-thymidine incorporation studies. The report generated by this program includes descriptive statistics such as the mean, percentage change from control and t-test probability. Special program features allow for flexibility in experimental protocol design, user-defined default program options, and automatic result storage on disk for subsequent archiving purposes.

A short guide is given for the planning of nerve fiber morphometry using computer-assisted methods. A new computer program is introduced which allows, among other factors, correction for myelin sheath shrinkage. If myelin shrinkage is not corrected for, there will be false high values for axon caliber and false high values for axon caliber and false low values for sheath thickness. The magnitude of the skew produced by this factor is shown on hand from computer editing.

In most models of capillary gas exchange, the binding curves for O2 and CO2 are represented by simple analytical expressions, and the interactions among the haemoglobin ligands are either neglected or are assigned fixed values independent of PO2, PCO2, pH and red cell DPG. We here present algorithms and a computer program in which the binding curves are described in a near-rigorous manner. This enables solution of a set of typical equations for a unit of blood which undergoes gaseous and proton exchange. We have applied the algorithms to the problem of calculating pulmonary blood flow from the gaseous exchange in the lung by the single-breath method of Kim et al. (1966), where the CO2 binding curves of arterial and mixed venous blood are approximated by straight lines. The application of the algorithms shows that this approximation introduces significant errors in the calculated pulmonary blood flow.
