The use of leading marks in pilotage is a procedure familiar to all seamen, and wherever leads are sufficiently easy to recognize on the screen the technique can be extended to use with radar, due note of the lowered degree of precision being taken. In this account of a passage through the exit to Singapore Strait, Captain Robb, a shipmaster of the Blue Funnel Line, and author of several works on radar use at sea, describes a less well known method in which off-set marks are used for conning the ship by radar. A similar technique was suggested in the Journal (9, 445) by Mackay.

For a lattice [Formula: see text] of a simply connected solvable Lie group [Formula: see text], we describe the analytic germ in the variety of representations of [Formula: see text] at the trivial representation as an analytic germ which is linearly embedded in the analytic germ associated with the nilpotent Lie algebra determined by [Formula: see text]. By this description, under certain assumption, we study the singularity of the analytic germ in the variety of representations of [Formula: see text] at the trivial representation by using the Kuranishi space construction. By a similar technique, we also study deformations of holomorphic structures of trivial vector bundles over complex parallelizable solvmanifolds.

Cortical undercutting, as an alternative to standard leucotomy and to the major operation of topectomy, was devised by three surgeons independently. Scoville (1949) published his preliminary results soon after McKissock had begun to do rostral leucotomies. Both have continued to use this type of operation (Scoville et al., 1951; Scoville, 1954) but Ferey (1950), the third to develop a similar technique, was disappointed with the results and soon abandoned it (Ferey, 1953). McKissock (1951) reported the initial impressions of the results in 100 cases and by the end of 1952 had operated on 240 cases. During 1953–54, 1½ to 5 years after operation, I followed up these patients, visiting 175 of them in their homes, and 35 in hospital. Personal follow up was refused or for some reason impracticable in 17 cases, including 4 whose case notes had been destroyed; 13 others had died before the survey was made.Partridge (1950) reported a follow up study of 300 cases operated on by the same surgeon by his “standard” technique (McKissock, 1943); he had the advantage, which I had not, of being able to see his patients before operation. I have had to work retrospectively, and the case notes available, whilst often excellent, had usually not been made with the idea that they would be needed for follow-up purposes. I have not, therefore, thought it right to draw more than broad conclusions from this study.

The volumetric coefficient is widely used in various calculations related to the estimation of petroleum reserves, crude oil production, preparation and transport of oil. The existing methods of its calculation determination are mainly empirical that makes it difficult to use them in solving various tasks, primarily optimization problems. The article is devoted to the development of similar technique in the form of analytical dependence, devoid of the noted shortcomings. For this purpose, the provisions of the hole theory of the dropping liquid are used, on the basis of which a theoretically and physically justified expression acceptable for a wide range of gas-saturated oils under different conditions is obtained. The acceptability of dependence is tested on oil data from different regions of the country and near abroad. The obtained dependence makes it possible to calculate the volume coefficient at a pressure equal to the pressure of oil saturation with gas.

Recurrent painful vaso-occlusive crises often represent sources of frustration and debilitation to those afflicted with sickle cell disease. We present two adolescents with sickle cell disease who have been able to gain control over the frequency and intensity of these crises by utilizing self-hypnosis. We feel that the utilization of similar technique(s) may allow many ill children and adolescents to obtain mastery over abnormal physiologic processes concomitant with their particular disease status.

Abstract In a previous paper, the authors defined two binary term operations in orthomodular lattices such that an orthomodular lattice can be organized by means of them into a left residuated lattice. It is a natural question if these operations serve in this way also for more general lattices than the orthomodular ones. In our present paper, we involve two conditions formulated as simple identities in two variables under which this is really the case. Hence, we obtain a variety of lattices with a unary operation which contains exactly those lattices with a unary operation which can be converted into a left residuated lattice by use of the above mentioned operations. It turns out that every lattice in this variety is in fact a bounded one and the unary operation is a complementation. Finally, we use a similar technique by using simpler terms and identities motivated by Boolean algebras.

Atmospheric deposition is an important source of nutrients to the ocean, potentially stimulating primary production, but its relative effect on coastal eutrophication remains largely unknown. This paper presents data generated by the 3-D modelling program NEUTRO to assess the proportion of atmospheric nutrient fluxes, allowing a quantification of the relative contribution of atmospheric and ocean fluxes in the Singapore Strait. This work included an assessment of the importance of high concentration episodic inputs of nitrate-nitrogen associated with transport of polluted air onto the surface water. The NEUTRO model features a nutrient-fuelled food web composed of nutrients, plankton, and dissolved oxygen dynamics. Model simulations show that atmospheric deposition fluxes alone might contribute nitrate-nitrogen mass up to 15% into the Singapore Strait. This amount might be a significant contributor toward regional eutrophication when the system is under nutrient-depleted conditions. Model calibrations for temporal and spatial variability of nutrients qualitatively and quantitatively agreed with available measurements.

Abstract The Delves [Analyst (London) 95, 431 (1970)] cup atomic absorption procedure for determination of lead in blood has been studied in detail and modified to permit the direct use of aqueous standards. Precision has been improved by stabilizing the burner mount. The small nonspecific absorption is caused by molecular sodium chloride and potassium chloride, and can be compensated for by including sodium chloride in the aqueous standards. If the cups are pre-coated with albumin, aqueous standards can be used and the more complicated method of additions is obviated. A similar technique was used to examine the analysis of lead in urine.

Abstract. Sea level rise due to climate change is non-uniform globally, necessitating regional estimates. Peninsular Malaysia is located in the middle of Southeast Asia, bounded from the west by the Malacca Strait, from the east by the South China Sea (SCS), and from the south by the Singapore Strait. The sea level along the peninsula may be influenced by various regional phenomena native to the adjacent parts of the Indian and Pacific oceans. To examine the variability and trend of sea level around the peninsula, tide gauge records and satellite altimetry are analyzed taking into account vertical land movements (VLMs). At annual scale, sea level anomalies (SLAs) around Peninsular Malaysia on the order of 5–25 cm are mainly monsoon driven. Sea levels at eastern and western coasts respond differently to the Asian monsoon: two peaks per year in the Malacca Strait due to South Asian–Indian monsoon; an annual cycle in the remaining region mostly due to the East Asian–western Pacific monsoon. At interannual scale, regional sea level variability in the range of ±6 cm is correlated with El Niño–Southern Oscillation (ENSO). SLAs in the Malacca Strait side are further correlated with the Indian Ocean Dipole (IOD) in the range of ±5 cm. Interannual regional sea level falls are associated with El Niño events and positive phases of IOD, whilst rises are correlated with La Niña episodes and negative values of the IOD index. At seasonal to interannual scales, we observe the separation of the sea level patterns in the Singapore Strait, between the Raffles Lighthouse and Tanjong Pagar tide stations, likely caused by a dynamic constriction in the narrowest part. During the observation period 1986–2013, average relative rates of sea level rise derived from tide gauges in Malacca Strait and along the east coast of the peninsula are 3.6±1.6 and 3.7±1.1 mm yr−1, respectively. Correcting for respective VLMs (0.8±2.6 and 0.9±2.2 mm yr−1), their corresponding geocentric sea level rise rates are estimated at 4.4±3.1 and 4.6±2.5 mm yr−1. The geocentric rates are about 25 % faster than those measured at tide gauges around the peninsula; however, the level of uncertainty associated with VLM data is relatively high. For the common period between 1993 and 2009, geocentric sea level rise values along the Malaysian coast are similar from tide gauge records and satellite altimetry (3.1 and 2.7 mm yr−1, respectively), and arguably correspond to the global trend.
