Assessment and forecasting of lightning potential and its effect on launch operations at Cape Canaveral Air Force Station and John F. Kennedy Space Center

Lightning plays a pivotal role in the operation decision process for space and ballistic launches at Cape Canaveral Air Force Station and Kennedy Space Center. Lightning forecasts are the responsibility of Detachment 11, 4th Weather Wing's Cape Canaveral Forecast Facility. These forecasts are important to daily ground processing as well as launch countdown decisions. The methodology and equipment used to forecast lightning are discussed. Impact on a recent mission is summarized

Breakfast foods.

In the last few years various cereal products known as Breakfast Foods have been- placed on the market. Many of these foods have been prepared in an excellent manner, placed in clean boxes and are attractive to the consumer. The breakfast foods are regarded by many as a very expensive form of food material, while others, considering the palatableness of these preparations and the amount of milk and sugar consumed as part of the meal say that they are economical when everything is considered

A Study of a Contaminated Water Supply

A pure water supply is one of the most valuable possessions which nature can give to any community. The value of a pure water supply is realized more readily by those who live in a city or town where the population is concentrated than by those living in the country where the families are isolated

The Influence of Chlorine as Chlorides in the Determination of Oxygen Consumed in the Analysis of Water

One of the most valuable determinations in the analysis of water and sewage is the determination of the oxygen consumed. In the deep well waters of the state, the amount of chlorine in the form of chlorides in many cases is very high, as may be seen by the investigations of the Geological Survey on the artesian waters

The Preparation of Ammonia Free Water for Water Analysis

The preparation of water which will not give the yellow coloration with Nessler\u27s reagent is an important problem in the analysis of water. Where the laboratory water supply contains a small quantity of ammonia, suitable water for use in water analysis can no doubt be obtained by ordinary distillation and collecting that part of the distillate which is free from ammonia. The water supply of many laboratories will not permit of this ready method of preparing ammonia free water. The distilled water must be redistilled with sulphuric acid and potassium permanganate to obtain a satisfactory water which will remain colorless when the Nessler reagent is added to it. This method requires distillation in a glass flask and is subjected to the usual degree of breakage and loss

The Chemical Composition of Sewage of the Iowa State College Sewage Plant

The sewage plant of the college was constructed in 1898 from the designs and under the supervision of Prof. A. Marston, the college engineer. The plans and a short description of the work of the plant have been recently published and only the chemical investigations will be considered in this paper

Short oestrous cycles in sheep during anoestrus involve defects in progesterone biosynthesis and luteal neovascularisation

Anoestrous ewes can be induced to ovulate by the socio-sexual, 'ram effect'. However, in some ewes the induced ovulation is followed by an abnormally short luteal phase causing a so called, "short cycle". The defect responsible for this luteal dysfunction has not been identified. In this experiment we investigated ovarian and uterine factors implicated in male-induced short cycles in anoestrus ewes using a combined endocrine and molecular strategy. Prior to ovulation, we were able to detect a moderate loss of thecal expression of steroid acute regulatory protein (STAR) in ewes that had not received progesterone priming (which prevents short cycles). At and following ovulation we were able to identify significant loss of expression of genes coding key proteins involved in the biosynthesis of progesterone (STAR, CYP11A1, HSD3B) as well as genes coding proteins critical for vascular development during early luteal development (VEGFA, VEGFR2) suggesting dysfunction in at least two pathways critical for normal luteal function. Furthermore, these changes were associated with a significant reduction of progesterone production and luteal weight. Additionally, we cast doubt on the proposed uterine-mediated effect of prostaglandin F2α as a cause of short cycles by demonstrating both the dysregulation of luteal expression of the PGF receptor, which mediates the luteal effects of PGF2α, and by finding no significant changes in the circulating concentrations of PGFM, the principal metabolite of PGF2α in ewes with short cycles. This study is the first of its kind to examine concurrently, the endocrine and molecular events in the follicular and early luteal stages of the short cycle

The chemical composition of food preservatives. Solutions for testing cream and milk.

There are many substances which are found on the market at the present time intended for preserving food products under various brands and names. The claims made for these substances by the manufacturers would lead one to believe that the brand of substance for which the claim is made possessed a wonderful power for preserving food products. When these mixtures are examined it is found that they are composed of common substances and such that any one could readily prepare for a small part of the price charged for them. In the development of the dairy industry from the farm dairy to the creamery, it has been found that the processes connected with the industry must be controlled in an intelligent manner in order that success may resul
