Oestrous cycle synchronization and oestrus induction in indigenous and European cattle in Tanzania
Authors: Schmidt H. , Jöchle W. , Smidt D. 
Published: March 2009

SUMMARYFrom 1969 to 1971, 743 animals (indigenous Zebu and European dairy cattle, lactating or dry cows and heifers) received oestrous cycle synchronization treatments at government-owned and private ranches and farms in the Tanzanian highlands (West Kilimanjaro); 445 matching animals served as controls. Treatment schedules consisted of chlormadinone acetate (CAP) given daily for 14 days (10 mg/day) orally; or a single CAP injection (50 mg) followed by 4 or 5 days of oral treatment (10 mg/day) 9–12 or 11–15 days later. In addition, some groups received either estradiol valerate (5 mg) together with the CAP injection, or 10 mg/day mestranol from day 11 to 15, together with CAP; one treatment group received 1000 i.u. of HCG after the last CAP medication and were inseminated 12 and 24 h thereafter. Animals were either inseminated or bred naturally. With all treatment schedules, good synchronization, unimpaired fertility and consistently a significant reduction of anoestrus was achieved. Oestrogen treatments had no effects; treatment with 1000 i.u. of HCG was unsuccessful. Management factors, food supply and phase of reproductive life had significant impacts on treatment success and fertility. Synchronization can be used successfully under a wide range of management conditions to unfold existing potentials of artificial insemination in Bos indicus and Bos taurus in the tropics.
Regional body surface area of sheep
Authors: Bennett J. W. 
Published: March 2009

SUMMARYTwenty-three shorn, adult Merino sheep weighing 22·6–63·1 kg were killed and total skin surface area and eight regional skin surface areas measured after skinning. Bodyfat content (1·9–43·6% of body weight) was estimated from the tritiated-water space and body dimensions were recorded before slaughter.Body weight was the best single measure for predicting total area and regional areas, and little advantage was gained by using multiple regressions incorporating body weight, fat content and body dimensions. Proportional surface areas of all regions except the neck were significantly related to body weight; positively for the trunk, and negatively for the ear, lower leg, upper leg and head. Equations relating regional surface area (% total area) to body weight are presented.
Variation in pod length in spring rape (Brassica napus) and its effect on seed yield and yield components
Authors: Chay P. , Thurling N. 
Published: March 2009

SUMMARYTen selections from the cultivar China A, with widely different pod lengths, were compared in a single environment in Perth in 1983. Pod length was correlated positively with seed weight per pod but negatively with number of pods per plant. As a result, there was no significant relationship between pod length and seed yield, although the highest- and lowest-yielding lines were, respectively, longand short-podded.Two lines differing markedly in pod length were compared in a second experiment in 1984 in which sowing date and plant population density within a sowing date were varied. Although pod length was relatively stable, seed yield and some of its components were greatly affected by sowing date and plant density. Again, the long-podded line produced fewer pods with a greater weight of seed per pod than the short-podded line in most conditions. Compensation for greater seed weight per pod by a reduction in number of pods per plant was primarily responsible for the absence of significant differences in yield between lines in any treatment.Although long pods generally produced a greater weight of seeds per pod than short pods, the advantage in seed number and/or the weights of individual seeds was less than that expected pro rata for the much greater pod length. Indeed, short pods produced more seeds per unit length of pod than long pods. This suggested a less efficient distribution of assimilates within the longer pods, a greater amount being required to support the growth of pod walls than in short pods.Alternative approaches to using pod length as a criterion of selection for high yield are discussed.
The δ13C value of ruminant saliva and its effect on the estimation of the legume component of oesophageal extrusa samples
Authors: Jones R. J. , Lefeuvre R. P. 
Published: March 2009

SUMMARYThe C3 and C4 plant components in extrusa samples from oesophageally fistulated cattle can be estimated by δ13Canalysis. However, contamination with saliva containing bicarbonates could cause bias in the estimation of the C3 or C4 components. Saliva from animals fed C4 and C3 diets had δ13C values of – 4.37/103 and –15.97/103, respectively. Both values showed a large positive shift of c. 10 units relative to the diets, but the difference between feeds was maintained in the saliva. On theoretical grounds, contamination of the ingested feed with saliva should have caused a small (1·3–3·4% legume) negative bias when estimating legume percentage in the diet. This did not occur when saliva of known (PC was added to mixtures of C3 and C4 forages which were dried, ground and analysed for δ13C. It is postulated that CO2 was lost from bicarbonate when saliva was dried in contact with fresh plant material, and so no significant bias was detected. It would appear that the δ13C technique can be used to estimate the proportion of C3 and C4 components in oesophageal extrusa samples without significant bias from salivary contamination.
Phosphorus diffusion in soils in relation to some edaphic factors and its influence on P uptake by maize and wheat
Authors: Bahl G. S. , Singh N. T. 
Published: March 2009

SummaryLaboratory studies were conducted on four soils to ascertain the effect of P content and texture on the capacity factor (P buffering capacity) of soils and in turn the effect of these factors combined with moisture content of soil on the diffusion coefficient of P (Dp). A glasshouse experiment was conducted to study the relationship of Dp with P uptake by maize and wheat. The buffer capacity decreased by the application of P in all four soils. There was a significant negative correlation between buffer capacity and Olsen's extractable P but positive correlation with other soil factors. The relative influence of different soil variables on the buffer capacity was in the order: free iron > percentage clay > exchangeable aluminium. The Dp value increased significantly with applied P, the maximum (3·2-fold over control) being in Tolewal loamy sand. The increase in clay and moisture content of soil also increased the Dp value. The drymatter yield and P uptake was significantly correlated with Dp, the r value being higher at later stages of growth of maize and wheat.
Effect of row orientation on growth, yield and yield attributes of wheat sown on three dates
Authors: Dhingra K. K. , Dhillon M. S. , Grewal D. S. , Sharma K. 
Published: March 2009

SummaryAn experiment to study the effect of row direction on the light interception, growth and yield of three wheat cultivars sown at three different dates was conducted at Punjab Agricultural University, Ludhiana during rabi seasons 1982–3 and 1983–4. The results showed that sowing in a north-south direction resulted in 0·20 and 0·22 t/ha higher yield than sowing east-west. Bi-directional sowing gave further increases of 0·30 and 0·18 t/ha over north-south direction during 1982–3 and 1983–4 respectively. Late sowing significantly reduced yield.
Inheritance of seed yield, maturity and seed weight of common bean (Phaseolus vulgaris) under semi-arid rainfed conditions
Authors: White J. W. , Ochoa R. M. , Ibarra F. P. , Singh S. P. 
Published: March 2009

SUMMARYTo develop an effective breeding programme for rainfed production of the common bean (Phaseolus vulgaris L.), the inheritance of seed yield under such conditions should be understood, preferably considering the effects of environment to account for site or season specificity. Thus, heritability, expected and realized gain from selection, and combining ability were evaluated for a nine-parent diallel of common bean without reciprocals but including parents, at two locations each in Mexico and Colombia, using the F2 and F3 population bulks. Heritability estimated from regressions of F3 on F2 ranged from 0·09 ± 0·18 (S.E.) to 0·75±0·25 for seed yield, from 0·26±009 to 0·34±009 for days to maturity and from0·57±004 to 0·80±004 for 100-seed weight. Expected gain from selection in the F2 was estimated as a percentage of the population mean, selecting the upper 20% of the populations. Expected gain in seed yield ranged from 1·8 to 8·4% in Mexico and from 6·5 to 28·1% in Colombia. Realized gains in seed yield in the F3 were 0·4–7·4% in Mexico and 2·9–15·7% in Colombia. Realized gain values for days to maturity were < 2·2%, and for 100-seed weight > 13·4%. General combining ability (GCA) mean squares (estimated using Griffing's Method 2, Model 1) were significant (P <0·01) and larger than those for specific combining ability (SCA) for all traits at all locations. The parents from the Mexican highlands tended to have a positive GCA effect for yield in Mexico but negative values in Colombia, whereas parents adapted to mid-elevation tropical environments showed the opposite tendency. However, all significant GCA values of breeding line V8025 were positive in both countries.
Long-term effects of primary cultivations on crop yields in a four-course rotation
Authors: Allen E. J. , Barker M. G. 
Published: March 2009

SUMMARYAn experiment is described which investigated for a period of 12 years the effects of four methods of basic cultivation – ploughing, rotary cultivating, cultivating and discing – on crop yields in a four-course rotation of winter wheat, sugar beet, spring barley followed by either potatoes (on one half of each main plot) or ley (on the other). The cultivations were carried out at two different times and each crop was grown at two levels of fertilizer.The method of cultivation had no effect on the yield of barley when weeds were controlled by chemicals but, in the absence of such control, the three deeper working methods of cultivation gave higher yields than discing towards the end of the experiment. In the case of wheat, ploughing generally led to the highest yields and rotary cultivating led to higher yields than either cultivating or discing after the ley. Discing led to relatively low yields, particularly with cultural methods of weed control at the lower level of fertility.With the sugar-beet crop, yields of sugar were higher in all rotations after ploughing than after cultivating or discing, irrespective of the method of weed control and although yields after rotary cultivating were similar to those after ploughing in the second rotation they did not consistently exceed those after cultivating or discing in the other two rotations. With discing, in the absence of chemical weed control the yields were markedly reduced in the last rotation period. Ploughing also led to the highest yields of potatoes but there were no consistent differences between the other methods and an apparent trend to lower yields after discing in the absence of chemical methods of weed control had not reached significance by the end of the experiment.It was concluded that ploughing was a more reliable method of seedbed preparation, not only with regard to consistency of performance under different conditions but also with regard to depth of working and extent of weed control.Ploughing appeared to be of particular value with the root crops used but the other methods led to satisfactory yields of the cereals grown after roots.
The sodium requirements of beef calves for growth
Authors: Morris J. G. , Murphy G. W. 
Published: March 2009

SUMMARYThirty-two beef calves (mean body weight 79 kg) were given a ration which depleted their body reserves of Na as was evidenced by a narrow Na to K ratio in the parotid saliva. Eight calves were then assigned to each of the following four treatments: low Na basal ration alone, basal ration plus either 1·09, 2·19 or 3·28 g Na/calf/day as bicarbonate.
Effects of dietary deficiencies of energy, protein and calcium on the pregnant ewe. I. Body composition and mineral content of the ewes
Authors: Sykes A. R. , Field A. C. 
Published: March 2009

SUMMARYForty 6½-year-old Scottish Blackface ewes were used in an experiment to investigate the effects of low protein and low calcium (Ca) intakes during pregnancy on body composition and mineral contents. Six sheep were slaughtered at the commencement of the experiment as controls; 28 were used in a 2 × 2 factorial experiment in which semipurified diets containing 11·8 and 6·0% crude protein (CP) and 1·2 and 0·11% Ca in the dry matter were offered to maintain non-esterified fatty acids (NEFA) and ketone bodies in the plasma at levels comparable to those found in hill sheep in winter. All ewes were slaughtered after parturition and the carcase dissected into soft tissue and skeleton fractions. Both fractions were dissolved in HNO3and the fat and mineral contents measured.
Performance of laying hens fed on diets containing heat-treated beans (Vicia faba L. var. minor), cotyledons and hulls

Published: March 2009

SUMMARYTwo experiments were conducted to study the influence of heat treatment of Vicia faba beans on the productive performance of laying hens fed diets containing large proportions of the beans. In the first experiment, the effects of extruding and pelleting the beans were studied while in the second experiment the effects of autoclaving at 121 °C for 30 min the cotyledons and hulls of the beans were evaluated. Hyline-W36 layers were used in the first experiment while two strains (Shaver-288 and Dekalb) of birds were used in the second experiment. Each experiment lasted 5 months during which data on egg production, egg weight, feed intake, mortality and body-weight gain of birds were collected. The results obtained indicated that heat treatment (extruding, pelleting and autoclaving) of the beans, cotyledons and hulls had no beneficial effect on the productive performance of laying hens fed on diets containing large proportions of the heated beans, cotyledons and hulls. Egg-size reducing factors appeared to be concentrated in the cotyledons rather than the hulls of the beans.
The effect of growing clover cultivars in association with barley cultivars upon grain yield of the barley crop in the year of sowing and the subsequent year
Authors: Stewart R. H. , Lynch K. W. , White Ethel M. 
Published: March 2009

SUMMARYIn 1974 three cultivars of barley of different straw lengths, Mazurka, Julia and Midas, were grown alone and with each of four cultivars of red and two of white clover in a split-plot randomized-block experiment of four replications. Although the barley cultivars differed significantly in yield the barley x clover interaction was not significant and yield of grain was not affected by the presence of the clovers.In the following year the entire experimental area was sown with Mazurka barley. Significantly higher grain yields were obtained on those plots sown with clover in 1974 than in plots where no clover had been sown. In no case was the combined yield of barley from the 2 years on any treatment involving clover lower than that of the mean of the no-clover control plots, although the highest increase in yield, 11% from the S.123 red clover treatment, over the no-clover control was not shown to be significant.
Beijing's Olympic Education Programme: Re-Thinking Suzhi Education, Re-Imagining an International China
Authors: Brownell Susan 
Published: March 2009

AbstractStarting in 2005, the largest “Olympic education” programme ever implemented by an Olympic host country was carried out in schools in Beijing and across China. By looking at the ways in which the policies for this programme were created and implemented, this article challenges the common perception that there was a “master plan” surrounding all aspects of the Beijing Olympics that was imposed by the party-state from the top down with the singular goal of promoting nationalist and communist ideology. It makes the point that by contrast with the suzhi (“quality”) education that preceded it, Olympic education contained a de-politicized patriotic education that linked national identity with sports heroes rather than political systems, and re-situated Chinese national identity within an international community in which it would now take its place as an equal partner.
Asymmetric development of Cotyledons of Tomato Embryo: Testing the prediction of Self-Organization
Authors: Reddy Chalapathy 
Published: March 2009

AbstractDevelopmental biologists have long strived to understand how organisms acquire shape and form. The architecture of the mature plant is established during embryogenesis. They have learned much about how gene expression controls the specification of cell type and about how cells interact with one another to coordinate such specific decisions. Far less is known about autocatalytic feedback flow of resource molecules regulating a plant and its parts, shape and form. Indeed, it has even been proposed that the development of shape is not under genetic control but rather is determined by physical forces. Asymmetric development of sinks that depend on common resource pool has been viewed as a consequence of autocatalytic feedback process of flow of resource units into them. The feedback process implies that the stronger a sink is relative to its competitors, the greater is its probability of getting further resources as a non-linear function of its resource drawing ability and sink size. We have shown that this model contrasts with that of sink strength dependent model in its prediction of the subsequent development of the initial asymmetry of growing cotyledons of the tomato embryo (Lycopersicon esculentum L.), when their resource drawing ability is enhanced by exogenous application of the growth regulators (NAA, GA and BA), we test these prediction and show that the results are in conformity with the autocatalytic model proposed by Ganeshaiah and Uma Shaanker.
Making a Broader Case for the Narrow View: Where to Begin?
Authors: Wallach Geraldine P. , Charlton Stephen , Christie Julie 
Published: March 2009

Purpose
This final article covering the topic of the interplay between decoding, comprehension, and content versus structure knowledge describes a set of language initiatives that are focused toward content area learning. Inspired by the work of their colleagues from diverse fields and their own work, the authors offer suggestions to clinicians who are interested in creating and delivering curriculum-relevant and strategic-based language intervention to school-age students with language learning disabilities (LLD).

Method
The discussion covers selected topics that form the foundation for an evolving intervention framework, including (a) understanding the content and structural requirements of textbooks, (b) integrating metacognitive and metalinguistic techniques into intervention goals and objectives, and (c) emphasizing meaning-based activities that cut across connected discourse (macrostructure levels) and sentence/word components (microstructure levels) of spoken and written language.

Conclusion
Starting with ways to find clues about “what to do” with students by looking in their textbooks, the authors continue with examples that integrate content and structure knowledge using social studies and science as backdrops for language intervention. The article ends with a reminder to clinicians to consider ways that preschool language intervention can be more effective in helping children prepare for the academic demands of the future.
Papuloerythroderma associated with monoclonal gammopathy of undetermined significance

Published: March 2009

ABSTRACTWe describe a 73‐year‐old Japanese man with papuloerythroderma overlapped with monoclonal gammopathy of undetermined significance (MGUS). Clinically, prominent erythroderma was associated with disseminated pruriginous papules, which were characteristically spared on the axillary and inguinal regions, the cubital and popliteal fossae as well as abdominal and small positional folds. Histopathologically, there was a significant perivascular infiltrate of lymphohistiocytic cells intermingled with eosinophils in the upper dermis. A biochemical profile revealed the presence of immunoglobulin G κ chain type monoclonal protein in the serum but the absence of hematological neoplasms. We diagnosed the patient as papuloerythroderma with MGUS, and treated him with narrow‐band ultraviolet B and topical steroid. His skin changes were improved, but the sharp γ‐globulin peak remained in the electrophoresis of serum protein. This case suggests an association between papuloerythroderma and MGUS.
Successful topical hemotherapy with a new occlusive dressing for an intractable ulcer on the toe

Published: March 2009

ABSTRACTTopical hemotherapy is a method of applying heparinized venous blood directly onto the surface of an ulcer, which is covered with an occlusive hydrocolloidal dressing. It is often effective on chronic ulcers with thick necrosis, because some proteinases and growth factors in plasma are probably involved in the digestion of necrotic tissues and the acceleration of granulation and epithelization. We treated a patient with an intractable ulcer on the toe caused by a peripheral circulatory disturbance due to her systemic sclerosis. As conventional topical hemotherapy cannot be applied to ulcers on the round tip of a toe, we made a device for occlusive dressing of topical hemotherapy which could successfully improve the previously refractory ulcer.
Measuring the quantitative performance of surgical operating lists: theoretical modelling of ‘productive potential’ and ‘efficiency’
Authors: Pandit J. J. , Stubbs D. , Pandit M. 
Published: March 2009

SummaryWe previously defined surgical list ‘efficiency’ as: maximising theatre utilisation, minimising over‐running, and minimising cancellations. ‘Efficiency’ maximises output for input; ‘productivity’ emphasises total output. We define six criteria that any measure of productivity (better termed ‘quantitative performance’) needs to satisfy. We then present a theoretical analysis that fulfils these by incorporating: ‘speed’ of surgery (with reference to average speeds), ‘patient contact’ (synonymous with minimising gaps between cases), and ‘efficiency’ (as previously defined). ‘Speed’ and ‘patient contact’ together constitute a ‘productive potential’. Our formula satisfies the pre‐set criteria and yields plausible results in both hypothetical and real data sets, To be productive in these quantitative terms, teams in any specialty need to achieve minimum quality standards defined by their sub‐specialty; to plan their lists to utilise the time available with no cancellations or over‐runs and to work at least as fast as average with minimal gaps between cases. ‘Productive potential’ combined with ‘efficiency’ yielding ‘actual productivity’ in our theoretical analysis more completely describes quantitative surgical list performance than any other single measure.
