Applying precision feeding techniques in growing-finishing pig operations

The high cost of feed ingredients, the use of non-renewable sources of phosphate and the dramatic increase in the environmental load resulting from the excessive land application of manure are major challenges for the livestock industry. Precision feeding is proposed as an essential approach to improve the utilization of dietary nitrogen, phosphorus and other nutrients and thus reduce feeding costs and nutrient excretion. Precision feeding requires accurate knowledge of the nutritional value of feedstuffs and animal nutrient requirements, the formulation of diets in accordance with environmental constraints, and the gradual adjustment of the dietary nutrient supply to match the requirements of the animals. After the nutritional potential of feed ingredients has been precisely determined and has been improved by the addition of enzymes (e.g. phytases) or feed treatments, the addition of environmental objectives to the traditional feed formulation algorithms can promote the sustainability of the swine industry by reducing nutrient excretion in swine operations with small increases in feeding costs. Increasing the number of feeding phases can also contribute to significant reductions in nutrient excretion and feeding costs. However, the use of precision feeding techniques in which pigs are fed individually with daily tailored diets can further improve the efficiency with which pigs utilize dietary nutrients. Precision feeding involves the use of feeding techniques that allow the provision of the right amount of feed with the right composition at the right time to each pig in the herd. Using this approach, it has been estimated that feeding costs can be reduced by more than 4.6%, and nitrogen and phosphorus excretion can both be reduced by more than 38%. Moreover, the integration of precision feeding techniques into large-group production systems can provide real-time off-farm monitoring of feed and animals for optimal slaughter and production strategies, thus improving the environmental sustainability of pork production, animal well-being and meat-product quality.

Kehitystoiminnan (RTD) systematisointi vaiheittaisen etenemisen ja portfoliojohtamisen avulla

Kehitystoimintaan liittyvä termi, innovaatio, voidaan määritellä monella eri tavalla. Riippumatta tarkasta määritelmästä innovaatioiden johtaminen voidaan määritellä prosessiksi, jossa eri suoritusvaiheet seuraavat toisiaan. Olennaista on erottaa innovaatioprosessin alkupää ja varsinainen kehitysprojekti toisistaan. Innovaatioprosessin alkupää mielletään usein sumeaksi ja vaikeasti hallittavaksi, kun taas kehitysprojektin johtamiseen on kehitetty systemaattisia menetelmiä, esimerkiksi Stage-Gate-prosessi. Kehitysprojektien johtamisessa ongelmaksi muodostuu resurssien riittämättömyys mahdollisiin projekteihin nähden. Tämä liittää kehitystoiminnan kiinteästi portfoliojohtamiseen. RTD-toiminnalla tarkoitetaan UPM Timberissä kehitystoimintaa, joka sisältää tuotekehityksen lisäksi myös prosessien ja teknologian kehitystoiminnot. UPM Timberiltä on puuttunut systemaattinen toimintamalli RTD-projektien läpiviemiseksi eikä niiden valintaan ja resurssien allokointiin ole ollut järjestelmää. Tutkimuksessa määritetään RTD-toiminnan kriittiset menestystekijät sekä muodostetaan UPM Timberille RTD-toiminnan kehityshaasteet. Niiden perusteella luodaan UPM Timberille systemaattinen toimintamalli, RTD-prosessikuvaus, RTD-projektien läpiviemiseksi sekä integroidaan portfoliojohtaminen toimintamalliin.

Ein XML-basiertes Modell für synchrone Gruppenarbeit auf gemeinsamen Informationsräumen

In dieser Arbeit wird ein generisches Modell fuer synchrone Gruppenarbeit auf gemeinsamen Informationsraeumen entwickelt. Fuer die Entwicklung dieses Modells muessen die Grundfunktionen fuer Anwendungen der synchronen Gruppenarbeit realisiert werden. Neben der Modellierung des Datenraumes (Datenmodell) und der operationellen Schnittstelle (Interaktionsmodell), muessen Mechanismen fuer die Darstellung der Aktivitaeten der Gruppenmitglieder auf dem Informationsraum (Awareness), sowie fuer die Synchronisierung gleichzeitiger Zugriffe verschiedener Benutzer auf dem Datenraum realisiert werden (Nebenlaeufgkeitskontrolle). Das Grundproblem bei der Loesung der Nebenlaeufigkeit liegt bei der Aufgabe der Isolation aus den klassischen ACID-Transaktionen zu gunsten von Awareness. Die rapide Entwicklung von Techniken der mobilen Kommunikation ermoeglicht den Einsatz dieser Geraete fuer den Zugriff auf Daten im Internet. Durch UMTSund WLAN-Technologien koennen Mobilgeraete fuer Anwendungen ueber die reine Kommunikation hinaus eingesetzt werden. Eine natuerliche Folge dieser Entwicklung sind Anwendungen fuer die Zusammenarbeit mehrerer Benutzer. In der Arbeit wird daher auf die Unterstuetzung mobiler Geraete besonderen Wert gelegt. Die Interaktion der Benutzer auf den gemeinsamen Datenraum wird durch einfache Navigationsoperationen mit einem Cursor (Finger) realisiert, wobei der Datenraum durch XML-Dokumente dargestellt wird. Die Visualisierung basiert auf der Transformierung von XML-Dokumenten in andere XML-basierte Sprachen wie HTML oder SVG durch XSLT-Stylesheets. Awareness-Informationen werden, aehnlich dem Fokus/Nimbus-Modell, von der Interaktion der Benutzer und der Ermittlung der sichtbaren Objekte bei dem Benutzer hergeleitet. Fuer eine geeignete Kontrolle der Nebenlaeufigkeit wurde der Begriff der visuellen Transaktion eingefuehrt, wo die Auswirkungen einer Transaktion von anderen Benutzern (Transaktionen) beobachtet werden koennen. Die Synchronisierung basiert auf einem Sperrverfahren und der Einfuehrung der neuen W-Sperre und der Grundoperationen readV und writeV. Das Modell (Groupware-Server) wird in der Arbeit in einem Prototyp implementiert. Weiterhin wird eine Java-Anwendung sowohl auf einem Desktop PC als auch auf einem Pocket PC (iPAQ 3970) implementiert, welche die Einsetzbarkeit dieses Prototyps demonstriert.

Early–Middle Holocene vegetation history, climate change and human activities at Lago Riane (Ligurian Apennines, NW Italy)

The radiocarbon-dated palaeoecological study of Lago Riane (Ligurian Apennines, NW Italy) presented here forms part of a wider investigation into the relationships between Holocene vegetation succession, climate change and human activities in the northern Apennines. The record of vegetation history from Lago Riane indicates that, since the end of the last glaciation, climate change and prehistoric human activities, combined with several local factors, have strongly influenced the pattern and timing of natural vegetation succession. The pollen record indicates an important change in vegetation cover at Lago Riane at ~8500–8200 cal. years b.p., coincident with a well-known period of rapid climate change. At ~6100 cal. years b.p., Fagus woodland colonised Lago Riane during a period of climate change and expansion of Late Neolithic human activities in the upland zone of Liguria. A marked decline in Abies woodland, and the expansion of Fagus woodland, at ~4700 cal. years b.p., coincided with further archaeological evidence for pastoralism in the mountains of Liguria during the Copper Age. At ~3900–3600 cal. years b.p. (Early to Middle Bronze Age transition), a temporary expansion of woodland at Lago Riane has been provisionally attributed to a decline in human pressure on the environment during a period of short-term climate change

Tangibilidade, classe de ativos e estrutura de capital das empresas listadas na BM&FBOVESPA

This study aims to investigate the influence of the asset class and the breakdown of tangibility as determinant factors of the capital structure of companies listed on the BM & FBOVESPA in the period of 2008-2012. Two current assets classes were composed and once they were grouped by liquidity, they were also analyzed by the financial institutions for credit granting: current resources (Cash, Bank and Financial Applications) and operations with duplicates (Stocks and Receivables). The breakdown of the tangible assets was made based on its main components provided as warrantees for loans like Machinery & Equipment and Land & Buildings. For an analysis extension, three metrics for leverage (accounting, financial and market) were applied and the sample was divided into economic sectors, adopted by BM&FBOVESPA. The data model in dynamic panel estimated by a systemic GMM of two levels was used in this study due its strength to problems of endogenous relationship as well as the omitted variables bias. The found results suggest that current resources are determinants of the capital structure possibly because they re characterized as proxies for financial solvency, being its relationship with debt positive. The sectorial analysis confirmed the results for current resources. The tangibility of assets has inverse proportional relationship with the leverage. As it is disintegrated in its main components, the significant and negative influence of machinery & equipment was more marked in the Industrial Goods sector. This result shows that, on average, the most specific assets from operating activities of a company compete for a less use of third party resources. As complementary results, it was observed that the leverage has persistence, which is linked with the static trade-off theory. Specifically for financial leverage, it was observed that the persistence is relevant when it is controlled for the lagged current assets classes variables. The proxy variable for growth opportunities, measured by the Market -to -Book, has the sign of its contradictory coefficient. The company size has a positive relationship with debt, in favor of static trade-off theory. Profitability is the most consistent variable in all the performed estimations, showing strong negative and significant relationship with leverage, as the pecking order theory predicts

A Compreensão da idéia do número racional e suas operações na EJA: uma forma de inclusão em sala de aula

The awareness of the difficulty which pupils, in general have in understanding the concept and operations with Rational numbers, it made to develop this study which searches to collaborate for such understanding. Our intuition was to do with that the pupils of the Education of Young and Adults, with difficulty in understanding the Rational numbers, feel included in the learning-teaching process of mathematics. It deals with a classroom research in a qualitative approach with analysis of the activities resolved for a group of pupils in classroom of a municipal school of Natal. For us elaborate such activities we accomplished the survey difficulties and obstacles that the pupils experience, when inserted in the learning-teaching process of the Rational numbers. The results indicate that the sequence of activities applied in classroom collaborated so that the pupils to overcome some impediments in the learning of this numbers

Chronic intermittent hypoxia alters glutamatergic control of sympathetic and respiratory activities in the commissural NTS of rats

Costa-Silva JH, Zoccal DB, Machado BH. Chronic intermittent hypoxia alters glutamatergic control of sympathetic and respiratory activities in the commissural NTS of rats. Am J Physiol Regul Integr Comp Physiol 302: R785-R793, 2012. First published December 28, 2011; doi:10.1152/ajpregu.00363.2011.-Sympathetic overactivity and altered respiratory control are commonly observed after chronic intermittent hypoxia (CIH) exposure. However, the central mechanisms underlying such neurovegetative dysfunctions remain unclear. Herein, we hypothesized that CIH (6% O-2 every 9 min, 8 h/day, 10 days) in juvenile rats alters glutamatergic transmission in the commissural nucleus tractus solitarius (cNTS), a pivotal site for integration of peripheral chemoreceptor inputs. Using an in situ working heart-brain stem preparation, we found that L-glutamate microinjections (1, 3, and 10 mM) into the cNTS of control rats (n = 8) evoked increases in thoracic sympathetic nerve (tSN) and central vagus nerve (cVN) activities combined with inhibition of phrenic nerve (PN) activity. Besides, the ionotropic glutamatergic receptor antagonism with kynurenic acid (KYN; 250 mM) in the cNTS of control group (n = 7) increased PN burst duration and frequency. In the CIH group (n = 10), the magnitude of L-glutamate-induced cVN excitation was smaller, and the PN inhibitory response was blunted (P < 0.05). In addition, KYN microinjections into the cNTS of CIH rats (n = 9) did not alter PN burst duration and produced smaller increases in its frequency compared with controls. Moreover, KYN microinjections into the cNTS attenuated the sympathoexcitatory response to peripheral chemoreflex activation in control but not in CIH rats (P < 0.05). These functional CIH-induced alterations were accompanied by a significant 10% increase of N-methyl-D-aspartate receptor 1 (NMDAR1) and glutamate receptor 2/3 (GluR2/3) receptor subunit density in the cNTS (n = 3-8, P < 0.05), evaluated by Western blot analysis. These data indicate that glutamatergic transmission is altered in the cNTS of CIH rats and may contribute to the sympathetic and respiratory changes observed in this experimental model.

Primary male osteoporosis is associated with enhanced glucocorticoid availability

OBJECTIVE: While systemic glucocorticoids compromise bone metabolism, altered intracellular cortisol availability may also contribute to the pathogenesis of primary male osteoporosis (MO). The objective of this study was to assess whether intracellular cortisol availability is increased in MO due to a distorted local cortisol metabolism. METHODS: Forty-one patients with MO were compared with age- and BMI-matched non-osteoporotic subjects after excluding overt systemic hypercortisolism (N = 41). Cortisol, cortisone and the respective tetrahydro-, 5α-tetrahydro- and total cortisol metabolites were analysed by GC-MS in 24 h urine. Apparent 11β-hydroxysteroid dehydrogenase (11β-HSD) enzyme activities, excretion of cortisol metabolites and calcium, and fractional urinary calcium excretion were assessed and related to BMD. RESULTS: Fractional and total urinary calcium excretion negatively correlated with BMD at all (P < 0.05) and at three of five (P < 0.05) measurement sites, respectively. While systemic cortisol was unchanged, apparent 11β-HSD enzyme activity in MO patients (P < 0.01) suggested increased intracellular cortisol availability. Total and fractional urinary calcium excretion was higher, with apparent 11β-HSD enzyme activities consistent with an enhanced intracellular cortisol availability (P < 0.05). CONCLUSION: Apparent 11β-HSD enzyme activities consistent with increased intracellular cortisol availability correlated with urinary calcium loss and reduced bone mineral density in MO. The changes in 11β-HSD activity were associated with both the fractional calcium excretion, suggesting altered renal calcium handling, and the absolute urinary calcium excretion. Both mechanisms could result in a marked bone calcium deficiency if insufficiently compensated for by intestinal calcium uptake.

Comparison of pain-resilient working individuals to population-based case controls with/without momentary low back pain

Background: Few studies have examined the 20% of individuals who never experience an episode of low back pain (LBP). To date, no investigation has been undertaken that examines a group who claim to have never experienced LBP in their lifetime in comparison to two population-based case–control groups with and without momentary LBP. This study investigates whether LBP-resilient workers between 50 and 65 years had better general health, demonstrated more positive health behaviour and were better able to achieve routine activities compared with both case–control groups. Methods: Forty-two LBP-resilient participants completed the same pain assessment questionnaire as a population-based LBP sample from a nationwide, large-scale cross-sectional survey in Switzerland. The LBP-resilient participants were pairwise compared to the propensity score-matched case controls by exploring differences in demographic and work characteristics, and by calculating odds ratios (ORs) and effect sizes. A discriminant analysis explored group differences, while the multiple logistic regression analysis specified single indicators which accounted for group differences. Results: LBP-resilient participants were healthier than the case controls with momentary LBP and achieved routine activities more easily. Compared to controls without momentary LBP, LBP-resilient participants had a higher vitality, a lower workload, a healthier attitude towards health and behaved more healthily by drinking less alcohol. Conclusions: By demonstrating a difference between LBP-resilient participants and controls without momentary LBP, the question that arises is what additional knowledge can be attained. Three underlying traits seem to be relevant about LBP-resilient participants: personality, favourable work conditions and subjective attitudes/attributions towards health. These rationales have to be considered with respect to LBP prevention.
