An analysis of growth of different cattle genotypes reared in different environments

Summary Calves from three breeds, Brahman, Hereford × Shorthorn (HS) and Brahman × HS (BX), were divided equally into two groups, one of which was treated every 3 weeks from birth onwards to control ticks and gastrointestinal helminths, and one of which was untreated. Mortalities, growth rates and levels of resistance to environmental stresses that affected both mortality and growth under grazing conditions were recorded for all animals up to weaning (6 months) and for all males up to 15 months of age. The Brahmans were the most and the HS were the least resistant to environmental stresses, each of which was shown to depress growth in proportion to its magnitude and to contribute to the high mortalities of the HS. All breeds responded positively to parasite control with the greatest response in both survival and growth in the HS breed and the least response in the Brahman breed. Samples of males from the various breed-treatment groups were taken into pens where they were protected from environmental stresses and fed both low-quality pasture hay and high-quality lucerne hay ad libitum. Measurements were made of fasting metabolism, maintenance requirement, voluntary food intake and gain, variables related to the growth potential of each animal. The HS animals had the highest whilst the Brahmans had the lowest values for each variable. However, despite their low growth potential, the Brahmans had the highest growtli rate, and the HS, despite their high growth potential, had the lowest growth rate, when growth was measured in the presence of all environmental stresses. When parasites were controlled, growth rates were highest for the BX, the breed with intermediate growtli potential, and did not differ between the HS and Brahmans. These interactions arose because of the different contributions of resistance to environmental stresses and growth potential to growth rate measured at the different levels of environmental stresses. The relevance of these interactions to breed evaluation and cross-breeding is considered. Growth potential and resistance to environmental stresses were negatively correlated both between and within breeds, though the latter was biased by the effects of compensation. The influence of these relationships on the likely outcome of selection for increased growth rate, both between and within breeds, is discussed.
Reconceptualising Civil-Military Relations in Africa

ABSTRACT Relations between African militaries, civilian authority and the public have undergone significant transformation over the past decades. Much of previous scholarship on civil-military relations tended to approach the subject through the idiom of the coup. Analysts in the 1960s initially presented the military in positive terms as a modernising agent, a representation cast aside in the throes of coups d’état, instability and rights violations at the behest of armed forces. This article revisits the conceptual and theoretical terrain in light of recent socio-political changes and in the wake of the peak of military coups on the continent. In reconceptualising civil-military relations, this article proposes a typology that combines the nature of modal relations with civilian authority and relations with the civilian public. The article analyses the different models of relations, tracing the domestic reconfigurations and external influences that structure news ways of civil-military engagement.
Experimental and numerical heat transfer from vortex-injection interaction in scramjet flowfields

ABSTRACT Air-breathing propulsion has the potential to decrease the cost per kilogram for access-to-space, while increasing the flexibility of available low earth orbits. However, to meet the performance requirements, fuel-air mixing inside of scramjet engines and thermal management still need to be improved. An option to address these issues is to use intrinsically generated vortices from scramjet inlets to enhance fuel-air mixing further downstream, leading to shorter, less internal drag generating, and thus more efficient engines. Previous works have studied this vortex-injection interaction numerically, but validation was impractical due to lack of published experimental data. This paper extends upon these previous works by providing experimental data for a canonical geometry, obtained in the T4 Stalker Tube at Mach 8 flight conditions, and assesses the accuracy of numerical methodologies such as RANS CFD to predict the vortex-injection interaction. Focus is placed on understanding the ability of the numerical methodology to replicate the most important aspects of the vortex-injection interaction. Results show overall good agreement between the numerical and experimental results, as all major features are captured. However, limitations are encountered, especially due to a localised region of over predicted heat flux.
LABOR HOARDING: AN OLD PHENOMENA IN MODERN TIMES? CASE STUDY FOR EU COUNTRIES

A consequence of similar institutional conditions of domestic labor markets in Europe is the permanent occurrence of the “labor hoarding” phenomenon, which entails non-immediate adaptation of employment to production changes. The article verifies whether the phenomenon of labor hoarding occurs in the European Union countries and what is its level and the direction of changes between 1996 and 2016. The empirical study of employment adjustments to the production volume showed that in the examined period the phenomenon of labor hoarding occurred in all countries of the European Union (excluding Spain). Labor hoarding was accomplished through a slight adjustment of the number of employees to production changes. At the same time, it was noticed that the companies were more flexible with adjusting the number of hours worked. This was particularly evident during global crises and was the consequence of other vital changes in national economies.
Knockdown of cysteine-rich 61 inhibits proliferation, migration, and invasiveness of prostate carcinoma PC-3 cells

The overexpression of wild-type cysteine-rich 61 (Cyr61) is associated with the aggressiveness of cancer and poor prognosis in different human cancers. The aim of this study was to examine the expression of Cyr61 protein in prostate adenocarcinomas and to investigate the effects of inhibiting Cyr61 expression using small interfering RNA on the proliferation, migration, invasiveness, and sensitivity of prostate carcinoma PC-3 cells to TNF-related apoptosis-inducing ligand. Cell proliferation was measured by XTT assay. Colony formation assay, wound healing assay, and Matrigel invasion assay were also examined. Immunohistochemical staining of prostate tumor tissues showed that prostate carcinomas had significantly increased Cyr61 level compared with benign glands adjacent to carcinoma. siRNA-based knockdown of Cyr61 resulted in decreased cellular proliferation, clonogenicity, migration, and invasion. At the same time, Cyr61 silencing effectively reduced the levels of phosphorylated Akt and integrin-β3. Cyr61-specific siRNA combined with TRAIL increased the apoptosis of PC-3 cells and the cleavage of apoptosis hallmarkers such as PARP and caspase-3. Taken together, our data provide evidence that Cyr61 modulates integrin-β3 level as well as PI3-kinase/Akt activity through which Cyr61 may mediate tumorigenesis, and suggest the potential importance of Cyr61 targeting on enhancing the therapeutic efficacy of prostate cancer.
Aspects of Drooping Sheoaks (Allocasuarina verticillata) that influence Glossy Black-Cockatoo (Calyptorhynchus lathami halmaturinus) foraging on Kangaroo Island

Abstract Glossy Black-Cockatoos on Kangaroo Island, South Australia, rely primarily on the kernels contained in the seed-cones of the Drooping Sheoak (Allocasuarina verticillata) as their food source. This study expands on previous studies of Glossy Black-Cockatoos foraging on Kangaroo Island by examining selection of patches, trees, branches and cones. The Cockatoos appeared to maximise food intake per unit of foraging time by foraging in trees with higher seed-fill and kernel ratio. Although not conclusive, this study suggests breeding birds may be more selective of high seed-fill and kernel ratio than non-breeding birds. Within the canopy of the Sheoaks, the Cockatoos cropped cones from branches with high densities of cones present on them. The Cockatoos also showed a preference for foraging in large trees, which appears to reduce the number of movements they have to make between trees. This would both limit the energetic costs of foraging and limit exposure to predators.
Effects of land use on temporal-spatial variability of soil water and soil-water conservation

Abstract The Loess Plateau of China suffers serious soil erosion primarily resulting from irrational land uses. Soil water plays a critical role influencing vegetation-restoration processes, but varies with temporal and spatial characteristics, of concern to many researchers. However, few studies consider the influence of deep soil water and varied weather patterns in a semi-arid region. Four vegetation types chosen for this study include artificial caragana shrubland, artificial alfalfa grassland, naturally restored vegetation land (Artemisia capillaries, Agropyron chistatum, Heteropapus altaicus Novop, Stipa bungeana, Stipa breviflora griseb and Lespedeza davurica), and bare land. Soil-water content at the top 400 cm depth was monitored continuously from 2004 to 2007 using a neutron probe. Water and wind soil erosion were investigated gravimetrically. Results showed that soil water varied greatly during May through October with different land-use types and annual precipitations. Soil water reached a lower level in both artificial vegetation lands in dry years but recharged with great variation in normal years. Soil water in two other lands tended to have similar changes with less variation as compared with the artificial vegetation lands. Soil water was intensively consumed with depth and continuously decreased in the deeper layers under the two artificial vegetations. The consumption in the artificial caragana shrubland was more intensive, while that in the artificial alfalfa grassland took place at greater depths. The naturally restored vegetation land had less soil-water consumption (close to the level in the bare land) as compared with the artificial vegetation lands. Soil-water content and its variability were increased along the slope with less variation over time. In general, both artificial vegetations effectively reduced the runoff and water-wind soil erosion in the third year after planting, while the naturally restored vegetation consistently showed weak conservation effects in the initial stage.

Equilibrium and kinetic studies on folding of the authentic and recombinant forms of human α-lactalbumin by circular dichroism spectroscopy

The equilibrium and kinetics of the unfolding and refolding of authentic and recombinant human R-lactalbumin, the latter of which had an extra methionine residue at the N-terminus, were studied by circular dichroism spectroscopy, and the results were compared with the results for bovine and goat R-lactalbumins obtained in our previous studies. As observed in the bovine and goat proteins, the presence of the extra methionine residue in the recombinant protein remarkably destabilized the native state, and the destabilization was entirely ascribed to an increase in the rate of unfolding. The thermodynamic stability of the native state against the unfolded state was lower, and the thermodynamic stability of the molten globule state against the unfolded state was higher for the human protein than for the other R-lactalbumins previously studied. Thus, the population of the molten globule intermediate was higher during the equilibrium unfolding of human R-lactalbumin by guanidine hydrochloride. Unlike the molten globule states of the bovine and goat proteins, the human R-lactalbumin molten globule showed remarkably more intense circular dichroism ellipticity than the native state in the far-ultraviolet region below 225 nm. During refolding from the unfolded state, human R-lactalbumin thus exhibited overshoot kinetics, in which the R-helical peptide ellipticity exceeded the native value when the molten globule folding intermediate was formed in the burst phase. The subsequent folding involved reorganization of nonnative secondary structures. It should be noted that the rate constant of the major refolding phase was approximately the same among the three types of R-lactalbumin and that the rate constant of unfolding was accelerated 18-600 times in the human protein, and these results interpreted the lower thermodynamic stability of this protein.
Discrepancy between preoperative endometrial sampling and hysterectomy diagnosis in endometrial cancer

Background: A study was conducted to determine the accuracy of preoperative endometrial sampling histology type and tumour grade results compared with the final postoperative diagnosis. Methods: This was a retrospective chart audit of patients with endometrial cancer and atypical hyperplasia admitted to Grey’s Hospital in Pietermaritzburg, South Africa, from January 2013 to December 2017. Results: Sixty patients met the inclusion criteria. For endometrial cancer histological types, the accuracy of preoperative endometrial sampling was 94.7% (36/38) for endometrioid adenocarcinoma, 42.9% (3/7) for serous papillary carcinoma, 85.7% (6/7) for carcinosarcoma and 75% (9/12) for atypical hyperplasia. A kappa value of 0.825 was obtained with a p-value of 0.000 for agreement between preoperative endometrial sampling and the final postoperative diagnosis. For endometrioid adenocarcinoma tumour grading 1–3 (G1–3), only 16/38 (42.1%) patients met the criteria to compare the pre- and postoperative results, which were as follows: of the eight patients with grade 1 tumour on preoperative sampling one patient (1.25%) was upgraded to grade 2 tumour postoperatively. There were no changes in tumour grading for grade 2 and 3 tumours, 3/3 and 5/5 respectively. Conclusion: Our study results for endometrioid adenocarcinoma are comparable to previous literature. However, there were significant discrepancies for non-endometrioid adenocarcinoma. Deficiencies that need to be addressed by laboratories in order to improve both preoperative surgical staging and postoperative adjuvant therapy planning were also highlighted.
Gender Specificity in Democratic Elections: International Implementability as an Exemplary for Indonesian Political Landscape

Women's participation in the electoral field is very important to be guaranteed by the state. In practice, there is often an imbalance in the number of female and male members. There needs to be a special policy to accommodate women's rights in these elections. This paper aims to examine how the legal construction in the electoral field is responsive to the right of women to participate. The method of approach used in this study is the socio-legal approach. The results found that the legal construction of gender justice-based elections to the electoral system is by increasing women's representation through the zipper system or alternating position between men and women in elections. In addition, this mechanism should be mutually agreed upon in various technical arrangements to implement this mechanism design.
The response of the male freshwater goby to natural and synthetic male courtship sound playback following exposure to different female sexual stimuli

Among teleosts, field and laboratory experiments have shown the playback of male courtship sounds often elicits competitive courtship and sound emission in the territorial male. However, the importance of female stimulation for the male response to the sound is poorly understood. In this study, playback experiments with the freshwater goby, Padogobius martensii, examined the response of resident males (i.e. males individually housed within laboratory tanks for at least 5 days) to natural and synthetic male courtship sounds after exposure to chemical or visual stimuli from a ripe female. All playback tests consisted of one experimental (sound playback) and two control treatments, all of equal duration. Three experiments were conducted on a first group of 12 males using natural courtship sounds. Experiment 1 consisted of playing back the sound to a male that had not exposed to female stimulation for at least 24 hr. The same male was exposed to the “female pheromone” by dropping a few cm3 of female holding water into the male's tank, just prior to playback (Experiment 2), or to the view of a live ripe female in a close-by tank, during playback (Experiment 3). The sound playback failed to elicit positive responses by males not exposed to female stimuli (Experiment 1), and did not increase courtship activity of the male in visual contact with the female (Experiment 3). However, it increased swimming activity and facilitated courtship and sound production in the male after an increase in sexual arousal by prior chemical stimulation (Experiment 2). In Experiment 4, the synthetic version of the courtship sound and one deprived of pulse-rate modulation and harmonic content (pure tone) were played back to 10 resident males following prior chemical stimulation. The synthetic courtship sound, but not the pure tone, was effective in eliciting positive responses by the sexually aroused male. Functional implications of the responses to the courtship sound for the territorial male are discussed. The results are relevant to the understanding of the role of sound communication and interception among gobies and to develop playback experiments in the field.
Medium Composition and Growth Regulator on Organogenesis Platycodon grandiflorum (Jacq.) A. DC. with Yellow Green Petals

This study was carried out to determine the optimal medium composition and growth regulators for the micropropagation of Platycodon grandiflorum (Jacq.) A. DC. Nodes containing yellow green petals were used as plant materials to execute the study. The best performance of adventitious root development was found in 1/4 strength of MS basal salt and the growth was satisfactory in the concentration of 1/2 MS medium. The best condition for adventitious root development and growth was observed in the higher concentration (5%) of sucrose and activated charcoal free 1/4MS medium respectively. Adventitious roots were developed at the controlled culture medium at pH 4.8 with a tendency of suppression with higher levels of pH. However, it was prevailed that the development and growth depended on the concentration of agar. The lower concentration of agar (0.4%) was performed better than that of higher concentration (1.2%), whereas the agar concentration (0.4%) showed the best performance for the development and growth of adventitious roots. For the development of shoots containing node, BA combined with IAA was more effective than kinetin with IAA or NAA. The highest shoot development (3.9 shoots per explant) was performed on MS medium supplemented with 0.1 mg/L BA and 0.5 mg/L IAA.
Trophic Exploitation and Arctic Phytomass Patterns

Aboveground phytomasses of tundra communities and changes in moss phytomass after a lemming peak were reviewed to test the prediction of the hypothesis of exploitation ecosystems that herbivory limits the aboveground phytomasses of moderately unproductive plant communities. Aboveground phytomasses of arctic meadows on Truelove Lowland where brown lemmings do not occur are about five times as great as corresponding values from Barrow which is within the range of the brown lemming. The combination of Barrow data and data from tundra communities on Hardangervidda with primary production less than 600 gm-2 yr-1 shows no significant correlation between aboveground phytomass and primary productivity, whereas a weak positive trend is obtained from Truelove Lowland where the herbivore trophic level is impoverished. Data from Kilpisjarvi suggest an 8.4-fold increase in moss phytomasses during 7 yr of low lemming densities. Both the geographical patterns and the short-term dynamics at Kilpisjarvi are in full agreement with the predictions of the hypothesis.
Seed bank dynamics in abandoned meadows during a 20‐year period in the Białowieża National Park

1 The relationship between size and floristic composition of the seed bank and vegetation dynamics was studied between 1976 and 1996 in 0.75 ha of an abandoned Cirsietum rivularis meadow. The plot was divided into 100‐m2 (10 × 10 m) quadrats and sampled 5‐yearly to map the vegetation and determine the soil seed bank.
EFFECT OF POSTMORTEM STORAGE AND CALCIUM ACTIVATED FACTOR ON THE MYOFIBRILLAR PROTEINS OF BOVINE SKELETAL MUSCLE

Myofibrils isolated from bovine longissimus (L), semitendinosus (ST) and psoas major (PM) muscles at-death and at 1, 2, 3, 6 and 10 days postmortem storage (2 and 25°C) were analyzed with sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis. One of the subunits of troponin, troponin T, disappeared from L and ST muscle during postmortem storage at 25°C, and concurrently a 30,000 dalton component appeared. Storage of muscles at 25°C accelerated these changes in myofibrils from L and ST muscles, but SDS polyacrylamide gels of PM muscle changed little during storage at either 2 or 25°C. Crude preparations of a Ca2+-activated factor (CAF) were isolated from bovine L, ST and PM muscles. Total CAF activity was high and similar in L and ST muscles, but PM muscle contained less than half the total CAF activity of L and ST muscles. Incubation of purified CAF with myofibrils isolated from at-death muscle caused Z-disk degradation and disappearance of troponin T and the simulataneous appearance of a 30,000 dalton component. That incubation of purified CAF with purified troponin caused degradation of troponin-T to a 30,000-dalton component indicates that the 30,000-dalton component in whole myotibrils originates from troponin-T. The effects of CAF on Z-disk and troponin-T degradation and the relative total activity of CAF in L, ST and PM muscles are similar to the effects of postmortem storage in myofibril fragmentation, myotibrillar protein degradation and WB shear force values. These parallel effects indicate that the limited and. specific proteolysis of myofibrillar proteins is caused by a Ca2+-activated factor endogenous to the muscle cell.
