Feeding Techniques To Increase Calf Growth In The First Two Months Of Life

End of project reportData from Cornell University and the University of Illinois in the USA suggested that average daily liveweight gains of 900 to 1000 g/calf/day could be achieved from birth to weaning provided the calf milk replacer (CMR) is formulated to meet the calf’s amino acid requirements for such a rate of gain. Their findings suggested a daily milk replacer DM allowance of 1250 to 1500 g/d with a crude protein content of 26 to 30%. A series of studies were undertaken, at ARINI with home born dairy calves and at Grange Beef Research Centre with purchased dairy calves, to determine the effect of increasing the daily milk replacer DM allowance and or increasing the crude protein content of the CMR on calf performance.The main outcomes of these studies were There was no growth or intake response in any of the studies to increasing the crude protein content of the CMP from 23% to 28%. Calf growth rates responded to increasing the dailymilk replacer allowance from 600 to 1200 g/day for both home bred and purchased calves. However, the effect was not significant post-weaning in any of the studies. In all of the studies (for both home reared and purchased calves) feeding a high level of CMRdecreased concentrate DM intake. However, the calves concentrate intakes were similar post-weaning. The home bred calves with free access to the milk replacer feeders failed to consume their 1200 g/day allowance. Calves offered 600 or 1200 g of CMR/day had average consumption of 554 and 944 g/d, respectively, in the milk feeding period. Feeding a high (1200 g/d) compared to a low level (600 g/d) CMRdiet for the first 56 days had no significant effect on carcass weight or carcass characteristics when purchased male calves were slaughtered off an ad libitum concentrate diet after 388 days. The final carcass weights were 231 and 240 kg for the respective 600 and 1200 g/d CMR. Reducing the fat content of the CMRfrom 18% to 12% did not have any effect on concentrate intake or liveweight gain

First Measurement of a Rapid Increase in the AGN Fraction in High-Redshift Clusters of Galaxies

We present the first measurement of the AGN fraction in high-redshift clusters of galaxies (z~0.6) with spectroscopy of one cluster and archival data for three additional clusters. We identify 8 AGN in all four of these clusters from the Chandra data, which are sensitive to AGN with hard X-ray (2-10keV) luminosity L_{X,H} > 10^43 erg/s in host galaxies more luminous than a rest frame M_R < -20 mag. This stands in sharp contrast to the one AGN with L_{X,H} > 10^43 erg/s we discovered in our earlier study of eight low-redshift clusters with z=0.06-0.31 (average z~0.2). Three of the four high-redshift cluster datasets are sensitive to nearly L_{X,H} > 10^42 erg/s and we identify seven AGN above this luminosity limit, compared to two in eight, low-redshift clusters. Based on membership estimates for each cluster, we determine that the AGN fraction at z~0.6 is f_A(L_X>10^42;M_R<-20) = 0.028 (+0.019/-0.012) and f_A(L_X>10^43;M_R<-20) = 0.020 (+0.012/-0.008). These values are approximately a factor of 20 greater than the AGN fractions in lower-redshift (average z~0.2) clusters of galaxies and represent a substantial increase over the factors of 1.5 and 3.3 increase, respectively, in the measured space density evolution of the hard X-ray luminosity function over this redshift range. Potential systematic errors would only increase the significance of our result. The cluster AGN fraction increases more rapidly with redshift than the field and the increase in cluster AGN indicates the presence of an AGN Butcher-Oemler Effect.Comment: ApJL Accepted, 5 pages, 2 figure

Normal pregnancy is associated with an increase in thrombin generation from the very early stages of the first trimester

Background: Pregnancy is a hypercoagulable state associated with an increased risk of venous thrombosis, which begins during the first trimester, but the exact time of onset is unknown. Thrombin generation, a laboratory marker of thrombosis risk, increases during normal pregnancy but it is unclear exactly how early this increase occurs. Methods: We assessed thrombin generation by Calibrated Automated Thrombography in women undergoing natural cycle in vitro fertilization, who subsequently gave birth at term following a normal pregnancy (n = 22). Blood samples were taken just prior to conception and repeated five times during very early pregnancy, up to Day 59 estimated gestation. Results: Mean Endogenous Thrombin Potential (ETP), peak thrombin generation and Velocity Index (VI) increased significantly from pre-pregnancy to Day 43 gestation (p = 0.024–0.0004). This change persisted to Day 59 gestation. The mean of the percentage change from baseline, accounting for inter-individual variation, in ETP, peak thrombin and VI increased significantly from pre-pregnancy to Day 32 gestation (p = 0.0351–&lt;0.0001) with the mean increase from baseline persisting to Day 59 gestation. Conclusion: Thrombin generation increases significantly during the very early stages of normal pregnancy when compared to the pre-pregnancy state. The increased risk of venous thrombosis therefore likely begins very early in a woman's pregnancy, suggesting that women considered clinically to be at high thrombotic risk should start thromboprophylaxis as early as possible after a positive pregnancy test

Alpha- and beta-adrenergic mediation of changes in metabolism and Na/K exchange in rat brown fat

Double- and triple-barreled ion-sensitive microelectrodes were used to measure changes in extracellular K+ and Na+ concentrations ([K+]o, [Na+]o) in brown fat. Redox states of different respiratory enzymes were measured simultaneously in order to correlate ion movements with metabolic activity. Trains of stimuli applied to the efferent nerves evoked two distinct increases in [K+]o. A first, small, rapid increase occurred within 10 s and accompanied a first, rapid membrane depolarization. A second, slow increase of [K+]o occurred several minutes after stimulation and accompanied a second, slow depolarization. A few seconds after stimulation onset, while the membrane was repolarizing and shifts in redox states indicated increases in lipolysis and respiration, [K+]o decreased. The [K+]o decrease was accompanied by an increase in [Na+]o, and could be partly blocked by ouabain. Phentolamine, an alpha-antagonist that blocks the first depolarization, also blocked the first, rapid [K+]o increase and part of the subsequent decrease. Propranolol, a beta-antagonist, had little effect on the first depolarization and the first increase in [K+]o, but blocked part of the subsequent [K+]o decrease and the second, slow [K+]o increase. The changes in [K+]o were almost completely abolished in the presence of both antagonists. It is concluded that brown adipocytes take up K+ and simultaneously lose Na+ in response to the interaction of noradrenaline with alpha- and beta-receptors, and this indicates a very early stimulation of the Na+ pump

THE USE OF SONGS TO INCREASE ENGLISH VOCABULARY TO THE FIRST GRADE STUDENTS OF SDN TUGU JEBRES NO.120 SURAKARTA

This report is written based on the job training activities done by the writer as an English Teacher in SDN Tugu Jebres No.120 Surakarta. The purpose of this report is to describe the use of songs to improve English vocabulary to the first grade student. Using songs can be good alternation to teach English to young learners because children like songs. In many cultures, songs are used to introduce or practice mother tongue to young children. By implementing the songs, the students are easier in understanding the meaning of the words and memorizing the vocabulary. It happened because first, songs are consisted of special rhythm that stimulates the brain to catch the lyrics. Second, there are many word repetitions in songs that is very helpful for young learners to memorize the new vocabulary. Third, singing is a happy and stress-free activity that brings different atmosphere in theclassroom so that the students feel more interested in learning English vocabulary. Songs are a motivating and enjoyable aid to learn language. Singing many English songs could add the students’ vocabularies. As the result, the scores of English is increasing well. Songs increase English vocabulary students

The challenges facing road-side ‘m-Preneurs’ in leap-frogging the constraints of ICTs in DCs: A Nigerian case study

Studies have shown that the number of mobile telecommunications operators in Nigeria has been on the increase since the first Global System of Mobile Telecommunications (GSM) licence was granted to MTN (Mobile Telecommunications Network) in 2001. With the increase in mobile telecommunications operators also has come an unprecedented increase in subscriptions. According to the Nigerian Communications Commission (NCC) data, between 2001 and 2006 for instance, mobile telephone subscribers in Nigeria jumped from 266, 461 to 32.3 million indicating an increase of 12, 030.18 %

Sensitivity of discharge and flood frequency to twenty-first century and late Holocene changes in climate and land use (River Meuse, northwest Europe)

We used a calibrated coupled climate–hydrological model to simulate Meuse discharge over the late Holocene (4000–3000 BP and 1000–2000 AD). We then used this model to simulate discharge in the twenty-first century under SRES emission scenarios A2 and B1, with and without future land use change. Mean discharge and medium-sized high-flow (e.g. Q99) frequency are higher in 1000–2000 AD than in 4000–3000 BP; almost all of this increase can be attributed to the conversion of forest to agriculture. In the twentieth century, mean discharge and the frequency of medium-sized high-flow events are higher than in the nineteenth century; this increase can be attributed to increased (winter half-year) precipitation. Between the twentieth and twenty-first centuries, anthropogenic climate change causes a further increase in discharge and medium-sized high-flow frequency; this increase is of a similar order of magnitude to the changes over the last 4,000 years. The magnitude of extreme flood events (return period 1,250-years) is higher in the twenty-first century than in any preceding period of the time-slices studied. In contrast to the long-term influence of deforestation on mean discharge, changes in forest cover have had little effect on these extreme floods, even on the millennial timescale

THE ROLE OF MENTAL DEVELOPMENT OF INDONESIAN NAVY’S FIRST FLEET TO INCREASE THE OPERATION READINESS OF THE NAVY OFFICER

Article 9 of Indonesian Law No. 34 year 2004 concerning Indonesian Defence Forces (TNI) rendering the Navy the task of maritime defense and security that requires of main equipment and weaponry system (Alutsista) such as Indonesian Warship (KRI). The Navy officer as the man who operate the warship requires a fit level of physical and mental to be able to execute the tasks optimally. One thing that is very important in maintaining and developing the mental readiness of navy officer is mental development. In the TNI Commander Decision No. Kep/940/XI/2017 dated November 21, 2017 concerning the Parental Guidelines for the TNI Mental Development Pinaka Baladika stated that the TNI mental development has a strategic role, task and function in building the capability and strength of the TNI for a strong national defense. The object of this research is the implementation of mental development in the First Fleet Command Headquarters, Indonesian Navy. The purpose of this study is to analyze the design of mental development that is conducted in the First Fleet Command Headquarters, Indonesian Navy. The analysis of the article is using role theory as the main theory which according to Levinson that roles related with three things, namely position or status, organization, and behavior. This study uses a qualitative methodology which primary data was obtained by interviews with officials at the First Fleet Command Headquarters who have duties for arranging, managing, executing, and evaluating mental development, and adding with navy officer representation. Meanwhile, secondary data was obtained by literature studies such as books, journals, magazines, letter of decisions, and etc. Data processing techniques was carried out by reducing data, presenting data, and drawing conclusions, using tools equipment NVIVO 12 plus for data coding. In this research, it was found that mental development at the First Fleet Command Headquarters had not managed its role optimally. One of the indicator is there are no position of a mental psychology officer, mental ideological officer, and mental traditional tradition officer in the organizational structure of First Fleet Command HQ. Mental development activities had not managed in accordance with the principles of modern management, especially in the planning level.Keywords: mental development, operation readines, first fleet command, Indonesian Navy, motivation
