    Notes: The historical background and present methodology used in compiling the U.K. official estimates of the stock of fixed capital are described. Mention is made of the possibility that with the development of commercial accounting direct estimates of capital stock may be derived from enterprise accounts at some future time. For the present, however, an indirect perpetual inventory approach is followed. Some of the deficiencies of the present estimates are discussed including the effects of possible biases in the life-length assumptions, price indices and the treatment of secondhand assets. Estimates of gross capital stock are given analysed by industry group of ownership and by type of asset.Some conceptual issues are discussed in relation to user requirements, including the distinction between the stock of capital and the flow of services from it.The authors conclude that little can be done to improve the perpetual inventory estimate of fixed capital in the U.K. without devoting more resources to the collection and analysis of new information, particularly on the service lives of fixed assets, the extent of leasing and the transfer of assets between industries.

    MINIMUM ENTROPY DECONVOLUTION WITH AN EXPONENTIAL TRANSFORMATION (1979)

    Notes: The Minimum Entropy Deconvolution (MED) technique of Wiggins (1977) represents a breakthrough in deconvolution and will undoubtedly find wide application in many fields. MED does not require any phase assumptions about the disturbing function and seeks a deconvolved output which consists of the smallest number of large spikes consistent with the input data.The efficiency of MED is much improved when an exponential transformation is incorporated into the algorithm. This is particularly true when the input traces contain additive noise. In this case the noise suppression characteristics of MED are considerably enhanced by the transformation and the identification of smaller spikes is improved. This paper also presents a kurtosis criterion of simplicity rather than the varimax norm introduced by Wiggins. It appears that for a multiple trace input the kurtosis measure leads to improved results.

    Notes: Phosphate retention by soils is especially important for tile fields and rapid infiltration systems near lakes where eutrophication is a problem. The use and application of the phosphate adsorption isotherm test to estimate a soil's phosphate removal ability will be discussed. In New York State, the till soils had a greater phosphate retention ability than the outwash soils. Within the tills and within the outwashes, the more acid soils had a greater phosphate retention than the more basic or calcareous soils. The B horizon of many of the soils had a high phosphate capacity. However, this is often neglected in rapid infiltration systems because the waste water is discharged below the B horizon. The phosphate removal in column studies and field studies in rapid infiltration systems was found greater than predicted by the rapid isotherm test. Intermittent sand filters with two feet sand and underdrains were found to have a limited ability to remove phosphate. Methods to predict and design for phosphate retention by sands and soils are described.

    A STATISTISTICAL ANALYSIS OF HUMAN LYMPHOCYTE TRANSFORMATION DATA (1979)

    Notes: The lymphocytes from 107 maternal-foetal pairs were examined for their in vitro responsiveness, as determined by the incorporation of tritiated thymidine following stimulation with phytohaemagglutinin (PHA), candida, varicella, mumps, streptokinase-streptodornase (SKSD) and tetanus toxiod. The data were collected and analysed in two sequential groups (forty-seven and sixty) in order to determine whether the results were reproducible. The variable chosen for analysis was the difference (d) between the square roots of the isotope incorporation in the stimulated and control cultures because it gave the most symmetrical distribution of the data. The experimental error in the determination of maternal lymphocyte stimulation was 1.4-8.6% and of the and of the foetal lymphocytes, 1.0-16.6% depending upon the antigen or mitogen and its concentration. The data in the two sets of patients were statistically the same in forty-eight of the fifty-six analyses (fourteen antigen or mitogen concentrations in autologous and AB plasma for maternal and foetal lymphocytes). The statistical limits of the distribution of responses for stimulation or suppression were set by an analysis of variance taking two standard deviations from the mean as the limits. When these limits were translated into stimulation indices, they varied for each antigen or mitogen and for different concentrations of the same antigen. Thus, a detailed statistical analysis of a large volume of lymphocyte transformation data indicates that the technique is reproducible and offers a reliable method for determining when significant differences from control values are present.

    SATELLITE MICROWAVE OBSERVATIONS OF SOIL MOISTURE VARIATIONS (1977)

    Notes: : Results from studies in the Illinois-Indiana and Texas-Oklahoma areas indicate that satellite microwave observations at the 1.55 cm wavelength are responsive to relative moisture variations in the near surface layer of the soil. Because significant vegetation cover absorbs the 1.55 cm microwave emission from the soil, the target area must be predominately bare soil or low density vegetation cover for meaningful measurements to result. The 25 km resolution of the satellite sensor limits application of the microwave techniques to large areas such as watersheds or agricultural districts rather than individual fields. In general, at 1.55 cm. there is an inverse relationship between microwave brightness temperature and changes in soil moisture levels (as indicated by antecedent rainfall) in agricultural regions before the planting of crops or during the early growing season when vegetation cover is sparse. Even early season observations should be of great value in deciding on the time and type of crop planting and for initial irrigation scheduling when the root zone is still in close proximity to the surface.

    Development of relief on a Middle Jurassic cemented sea floor: origin of submarine pseudo-anticlines in the Bathonian of Normandy (1979)

    Notes: On the foreshore east of Luc-sur-Mer, Normandy, an Upper Bathonian hard-ground which caps a sponge biostrome has been thrown into a series of troughs and ridges, the latter sometimes with very steep flanks. Faunal orientation and encrustation of extensive undercuts demonstrate that these structures are of a syn-sedimentary origin. They are interpreted as submarine pseudo-anticlines which have a composite origin. The following three factors are thought to have contributed to their formation: (a) a primary morphological differentiation of the underlying biostrome; (b) sediment expansion caused by force of crystallization during hardground formation; and (c) differential compaction, being greater where the hardground overlies mainly inter-reef mud as compared with the rigid sponge framework. The main episode of this compaction occurred at an early stage in the life of the hardground. Subsequent erosion, colonization by encrusters and borers, and burial beneath a fossiliferous clay were the final stages in the history of these pseudo-anticlines.

    THE OLD AND THE NEW IN SEISMIC DECONVOLUTION AND WAVELET ESTIMATION (1977)

    Notes: Various seismic deconvolution operators can be determined by estimating a seismic wavelet and subsequently designing an appropriate inverse filter which converts the wavelet to a spike. Seismic wavelets and deconvolution operators must be estimated in a time adaptive sense due to the nonstationarity of the seismic trace. The wavelet estimation methods considered in this paper either use the assumption of a minimum phase wavelet and a random impulse response, or the assumption that the wavelet cepstrum is readily separable from the cepstrum of the seismic trace. The former assumption is required in using the Hilbert transform and Wiener-Levinson wavelet estimations, while the latter assumption is used in homomorphic deconvolution. These wavelet estimates can be used in the design of multichannel Wiener and Kalman deconvolution operators. Multichannel usage of homomorphic deconvolution can also be implemented through various types of cepstral stacking.The discussion of deconvolution filter design focuses on the problems of filter length, degree of prewhitening, and nonstationarity. In designing time adaptive deconvolution filters, the autocorrelation function can be used to monitor the nonstationarity of the seismic trace. The autocorrelation function, which is used in the computation of least squares inverse filters, can be estimated in an optimum fashion by using the maximum entropy method. Differences between minimum phase Wiener deconvolution and maximum entropy deconvolution become more pronounced for shorter data gates. As a result, the maximum entropy approach is preferred for time adaptive deconvolution.In this paper, the performance of various wavelet estimators and inverse filters is discussed using real and synthetic seismic data. Discussions of homomorphic deconvolution and maximum entropy prediction error filtering are merged with descriptions of conventional approaches to deconvolution.

    Notes: Either of two fumigant nematicides, dazomet or dichloropropane-dichloropropene, applied prior to planting at 336 kg a.i./ha, gave good control of Longidorus elongatus (de Man) Thorne & Swanger and transmission of raspberry ring spot virus in a raspberry plantation. Either of two oxime-carbamate nematicides, aldicarb or oxamyl, at 7.84 kg a.i./ha gave only moderate control of nematode numbers and only limited control of virus transmission.Quintozene (89.6 kg a.i./ha) decreased L. elongatus numbers slowly and controlled virus transmission in the field. Pratylenchus crenatus Loof numbers were controlled only by dazomet, dichloropropane-dichloropropene or aldicarb.In a supplementary field experiment the acquisition and transmission of tomato black ring virus by L. elongatus in strawberries was inhibited by oxamyl for less than 19 wk. Little difference in the duration of the inhibitory effect was found between the three rates of oxamyl tested (5.56, 11.2 and 22.4 kg a.i./ha).

    Notes: Pigs were reared on different diets, leading to different percentages of PUFA'S (up to 40%) in their fat. Pork products, mostly cold, were evaluated by a consumer panel for overall preferences, and on various characteristics such as color, etc. Panel members evaluated also the acceptability of the products. Results show that the modified pork products do reasonably well, compared with standard products. The biggest exception is liver sausage.

    Notes: The effects of five different vegetable oils with a high content of P.U.F.A. on the preferences of a consumer panel for five common fried foodstuffs were investigated. Prior to that, the possibility that a panel could distinguish between different brands of one kind of oil was investigated. It was found that the very large majority of people is unable to discriminate between different brands of one kind of oil. As regards the preference study: Only for beef and chicken were any statistically significant results found. The differences were so small however, that no practical consequences can be expected.
