Effects of supplying leucine and methionine to early-lactating cows fed silage-concentrate based diets with a calculated deficiency in leucine and methionine

In a 2 〈 2 factorial approach the productive and metabolic response of 24 multiparous Brown Swiss cows fed rations calculated to be deficient in leucine (0.9-fold of requirements) and methionine (0.8-fold) to supplementation either of one or both of these amino acids were investigated. On a dry matter basis the rations consisted of 29% grass silage, 20% maize silage, 6% hay, and 45% concentrate. Blood plasma amino acid data confirmed the intended difference in metabolic supply of leucine and methionine keeping a low variation in the plasma levels of the other essential amino acids, particularly lysine. Live weight, milk yield as well as content and amount of milk fat were not affected by the treatments. Content and amount of milk protein were significantly reduced relative to initial level without additional methionine. Nutrient digestibility and nitrogen balance remained widely unchanged by the supplementations. Except of plasma aspartate amino transferase, cholesterol, creatinine and ornithine, which responded to methionine, hormones, enzyme activities as well as plasma, urine and milk metabolites were not systematically influenced by leucine and methionine sup- ply. The present results gave clearer indications for a deficiency in methionine than in leucine.
Factors Affecting Customer Satisfaction in Mobile Telecommunication Industry in Bangladesh

Identification of factors responsible for customer satisfaction is a key concern of marketing scholars and marketers in now a days and it will remain in the future. There is considerable evidence that quality factors affecting customer satisfaction in numerous ways. However, this empirical study is initiated to find out what particular factors responsible for customer satisfaction in the mobile tel- ecommunication industry in Bangladesh. 282 samples have been collected through structured questionnaire; study reveals that service innovativeness, service reli- ability, service competitiveness and service consistency have significant influence on making customer satisfied and the operator’s network/signal coverage, pricing, offering, fulfillment of customer demand, value added service, brand value and op - erators contribution for society have insignificant influences on making customer satisfied at five percent level of significant at multiple regression analysis. On the basis of these findings; study concludes that in promoting customer satisfaction mobile service providers should be concerned for factors responsible for insignifi- cant influence on customer satisfaction and care of those factors have significant influence on promoting customer satisfaction in telecommunication industry in Bangladesh.
EFFECTIVE TEMPERATURE DIFFERENCES AMONG COVER TYPES IN NORTHEAST MINNESOTA

Climate is probably one of the ultimate influences on the southern boundary of moose (Alces alces) distribution because moose are sensitive to warm temperatures in both summer and winter. In 4 different cover types in northeastern Minnesota we compared ambient temperatures to black globe temperatures that measures mean radiant temperature of the environment. The 4 cover types were mixed forest, treed bogs, coniferous forest, and deciduous forest that comprised ~85% of home ranges of radio-collared moose in northeastern Minnesota. Ambient temperature measurements taken from a weather station within the study area exceeded assumed physiological thresholds of 14 and 20o C for 50 and 33% of the study period, respectively. Black globe temperatures varied among cover types and temperature differences increased within cover types as ambient temperature increased. The greatest difference between deciduous and conifer cover was 2o C in black globe temperature and occurred during warm periods when skies were clear. The biological significance of these temperature differences is not clear and suggests the presence of alternative cooling mechanisms of cover types, such as water and possibly soil and duff layers acting as heat sinks. Use of these potential alternative cooling mechanisms should be considered in future research.
Analysis of water quality of Selameko man-made reservoir using physico-chemical parameters for fishery, Debre Tabor, South Gondar (Ethiopia)

Water quality is connected with physical, chemical and biological (including bacteriological) characteristics and these characteristics are determined the healthy status of any aquatic ecosystem. To determine whether the water quality of Selameko reservoir is good for fishing, physico-chemical parameters measurements were made. Water quality parameters, such as temperature, water transparency, water depth, dissolved oxygen, pH, total dissolved solids, phosphate, nitrate, and silicate were measured in-situ from two sites (littoral and open water zone) of the reservoir. Temperature of the water of the reservoir ranged from 18.7 to 24.2°C,water depth (only for open zone) 10.5 to 13.04 m, pH 7.01 to 8.01, DO 5.0 to 6.15 mg/l, transparency depth 32 to 97 cm, TDSs 67.1 to 137.2 ppm, NO3-N 0.1 to 2 mg/l, PO4-P 0.08 to 0.83 mg/l and Silicate 0.09 to 22.5 mg/l. ANOVA result of the physicochemical parameters showed presence of significance difference among seasons and between sites (p<0.05). The study concluded that some of physicochemical parameters such as NO3-N and PO4-P were indicated the presence of reservoir water pollution and not good fishing activity. The reservoir water was eutrophic (productive) throughout the year. To avoid such pollution, basin and reservoir management are recommended. Key words: Physco-chemical parameters, fish, temperature, aquatic.
Bias in the tone of forward‐looking narratives

Abstract We extend the prior literature on biased disclosure decisions by examining whether, when and how managers bias the tone of forward‐looking narratives. In order to measure tone we employ techniques of manual content analysis and we aggregate positive, neutral and negative statements into an overall measure of tone.We then analyse the frequency of positive and negative statements for firms with large impending year‐on‐year changes in sales and operating profit margin, and we regress tone cross‐sectionally on four managerial incentive variables that are unrelated to the private signal about future trading, namely loss status, sign of earnings change, business risk, and the existence of an analyst earnings forecast. We find that firms with large impending performance declines bias the tone in the outlook section upwards. Also, we find that loss firms, risky firms and firms with an analyst earnings forecast provide a more positive tone, while firms with an earnings decline provide a more negative tone. Finally, we observe that for a majority of our managerial incentive variables the main vehicle of biasing the tone is to change the number of negative statements, not the number of positive statements. Overall, our findings are difficult to reconcile with predictions from signalling models, but they are consistent with the alternative view of impression management. Our results have policy implications. In particular, they suggest that there is a need to reconsider the current largely unregulated nature of forward‐looking narratives.
Impact of Different Mobility Models on AODV Protocol in MANET with NS-2.35 and Bonnmotion-2.1a

: Mobile Adhoc Networks are self configuring,infrastructureless network (i.e) a network without any existing network infrstructure or centralized administrationn. To faclitate communication among the nodes in MANET, multiple hops are needed due to the limited range of wireless network interfaces. In order to exchange data among the nodes ,a routing protocol[1] is used to discover the routes. The goal of routing protocol is to efficiently construct a route between a pair of nodes with minimum routing overhead and bandwidth consumption. In this paper, the performance of the best mobility model with the use of AODV routing protocol is implemented. Link breaks and Average Link Changes are calculated for different mobility models like Random Walk,Gauss Markov,Manhattan using BONNMOTION 2.1a[5] by varying the Network Size,Simulation Time and Transmission Range in order to decide on the best mobility model . Further the correctness of the best mobility model is investigated by the assessment of performance paramaeters like packet delivery ratio (PDR), average end to end delay, and throughput. NS-2.35[6] was used to produce the networks, services and situation personality. According to th e simulation study,the best mobility model is manahattam mobility model with less number of link breaks and average link changes and also with the instigation of performance metrics.
PDGF-R Expression in Preneoplastic and Neoplastic Hepatocellular Lesions: A Rat Model N-nitrosomorpholine Stop Experiment

Background : N-nitrosomorpholine (NNM) is a genotoxic hepatocarcinogenic agent. Preneoplastic and neoplastic hepatocyte lesions were induced in rats by oral exposure to NNM (200 mg/L) in a stop model experiment. Platelet-derived growth factor receptor (PDGF-R) is a tyrosine kinase receptor that works with PDGF, stimulating cellular growth and proliferation. The present study was designed to determine the role of PDGF-R expression in hepatocellular neoplasms and precursors. Methods : Seventeen rats out of a starting number of 30 died. From the fifth week until the 24th week one or two rats were evaluated. Preneoplastic single cells or foci, foci of altered hepatocytes (FAH) hepatocellular adenomas (HCA) and hepatocellular carcinomas (HCC) were studied histologically, and the expressions of GSTp and PDGF-R by immunohistochemistry. Results : At the fifth week, GSTp + single cells showed PDGF-R expression (20.8±5.8%). At the sixth week, GSTp+ single cells, located at periportal areas, co-expressed PDGF-R (43.4±9.6%). Over the next several weeks periportal hepatocytes showed weaker PDGF-R expression but no GSTp. GSTp+ FAH, and all HCA, demonstrated no PDGF-R expression. However, nine out of 10 (90%) HCC showed PDGF-R expression. Conclusions : These data showed that there were two peaks of PDGF-R expression, and suggest that the earlier expression is related with the response to NNM-induced hepatocyte toxicity, and that the later response is associated to malignant transformation.
PHOSPHORUS AND ALGAE REMOVAL VIA ADSORPTION

Algal bloom, commonly known as Red Tide in coastal areas, has become one of the major problems facing desalination plants due to the high biomass concentration of microalgae associated with it. It causes operational problems (i.e. membrane fouling) in addition to health risk associated with deadly species of algae. Phosphorus pollution is considered to be the primary cause of red tide since most of microalgae species grow rapidly in the presence of high phosphorus concentrations. Many recent studies showed the efficiency of using adsorption for phosphorus removal from wastewater; however, none addressed its removal from seawater or the removal of algae via adsorption. The objective of this dissertation was to investigate the efficiency of using adsorption as a treatment process to remove microalgae and phosphorus. A variety of phosphorus adsorbents were tested and compared with each other in order to determine the most efficient material for the treatment system. Batch and fixed bed column tests were conducted to assess the performance of the treatment system for algae and phosphorus removal. The effects of different parameters were investigated to maximize phosphorus and algae removal. Chlorophyll-a concentration was measured as an indicator for algae concentration. Preliminary results showed that activated alumina was the most suitable adsorbent (out of the ones tested in this research) for phosphorus removal from synthetic water. Further results obtained from batch experiments revealed that acidic conditions (pH = 5) and an adsorbent particle size of 0.6 mm were the most feasible experimental conditions for treating both phosphorus and microalgae from actual seawater. The removal percentages were more than 84% for phosphorus and more than 40% for chlorophyll-a using only 4 g/L of activated alumina. Column tests showed more than 50% phosphorus and chlorophyll-a removals even after processing 5000 pore volumes. The pattern of the results suggested that, most probably, adsorption was not the main mechanism of microalgae removal. Phosphorus recovery proved to be reasonably applicable under extreme alkaline conditions (pH = 13.1).
University of Groningen The Fornax Deep Survey with VST . II . Fornax A : A Two-phase Assembly Caught in the Act

As part of the Fornax Deep Survey with the ESO VLT Survey Telescope, we present new gand r-band mosaics of the SW group of the Fornax Cluster. It covers an area of 3×2 square degrees around the central galaxy NGC1316. The deep photometry, the high spatial resolution of OmegaCam, and the large covered area allow us to study the galaxy structure, trace stellar halo formation, and look at the galaxy environment. We map the surface brightness profile out to 33′ (∼200 kpc ∼ 15Re) from the galaxy center, down to m ~ 31 mag g arcsec −2 and m ~ 29 mag r arcsec . This allow us to estimate the scales of the main components dominating the light distribution, which are the central spheroid, inside 5 5 (∼33 kpc), and the outer stellar envelope. Data analysis suggests that we are catching in the act the second phase of the mass assembly in this galaxy, since the accretion of smaller satellites is going on in both components. The outer envelope of NGC1316 still hosts the remnants of the accreted satellite galaxies that are forming the stellar halo. We discuss the possible formation scenarios for NGC1316, by comparing the observed properties (morphology, colors, gas content, kinematics, and dynamics) with predictions from cosmological simulations of galaxy formation. We find that (i) the central spheroid could result from at least one merging event (it could be a preexisting early-type disk galaxy with a lower-mass companion) and (ii) the stellar envelope comes from the gradual accretion of small satellites.
Leaf water potential, photosynthetic pigments and compatible solutes alterations in four grape cultivars under salinity

A hydroponic culture experiment was conducted to investigate the effects of different concentrations (0, 25, 50 and 100 mM) NaCl on own-rooted table grape ( Vitis vinifera L.) cultivars (red 'Rishbaba', red 'Sahebi', 'Dastarchin' and red 'Sultana') under greenhouse conditions. Cultivars were evaluated for growth analysis leaf area, leaf water potential and the chlorophyll a, b and carotenoid contents in relation to proline and soluble sugars accumulation. Salinity treatments caused a growth reduction (P ≤ 0.05) in all the cultivars. Also leaf water potential and chlorophyll a, b contents decreased whereas carotenoid, proline and soluble sugars increased with increasing NaCl concentration. 'Dastarchin' and red 'Sultana' showed the salt- sensitivity, the highest loss of growth, leaf water potential and chlorophyll content and the lowest accumulation of carotenoids, proline and soluble sugars. Also salt stress significantly (P < 0.001) increased the rate of lipid peroxidation in the all cultivars particularly in 'Dastarchin' and red 'Sultana'. The increase in malondialdehyde content indicated that salinity induced oxidative stress. There was a significant negative correlation between leaf water potential and NaCl concentrations (r 2 : -0.781, p < 0.001). A positive correlation was also found between lamina proline contents and NaCl concentrations (r 2 : +0.964, p < 0.001) for all salinity treatments. Considering overall results red 'Rishbaba' and red 'Sahebi' showed higher capacity to tolerate salinity when compared to 'Dastarchin' and red 'Sultana'.
Effect of Sowing Dates and Maize Cultivars in Growth and Yield ofMaize along with their Agro-Climatic Indices in Nawalparasi, Nepal

A field experiment on different maize cultivars planted at different sowing dates were accomplished at Kawasoti-5, Nawalparasi during spring season of 2013 to find suitable sowing date and maize cultivar for the location. Along with this, effect of sowing dates and maize cultivars on different agro-climatic indices were also calculated using formulas. Result showed that RML- 4/RML-17 produced higher kernel rows ear-1 (13.77), kernel per row (30.42) and test weight (244.9 g). Significantly higher grain yield was also found for RML-4/RML-17 (6.03 tha-1) compared to Poshilo makai-1 (4.73 t ha-1), Arun-2 (3.55 t ha-1) and Local (2.92 t ha-1). Earlier sowing date (7th April) produced higher kernel row-1 (27.97), kernel rows ear-1 (12.89) and 1000 grain weight (230 g). Significantly higher grain yield (5.13t ha-1) was obtained in earlier sowing date (7th April). Although the mean ambient temperature during research period was increasing with delayed sowing, days to attain different phenological stages decreased with late sowing. The statistically similar GDD was recorded for different sowing dates and higher PTI values were noticed with delay in planting. Similarly, heat use efficiency (HUE) was found higher in early sowing date. Arun-2 had small reduction in HUE so, it can be considered stable and best cultivar among the tested cultivars.
A Study of Intrusion Detection System Methods in Computer Networks

Intrusion detection system (IDS) is an application system monitoring the network for malicious or intrusive activity. In these systems, malicious or intrusive activities intrusion can be detected by using information like port scanning and detecting unusual traffic, and then they can be reported to the network. Since intrusion detection systems do not involve predefined detection power and intrusion detection, they require being intelligent. In this case, systems have the capability of learning. They can analyze packages entering the network, and detect normal and unusual users. The common intelligent methods are neural networks, fuzzy logic, data mining techniques, and genetic algorithms. In this research, the purpose is to study various intelligent methods.

Instrumented Model Slope Failure due to Water Seepage

Many slope failures have been observed to occur during or immediately after rainfall. Although conditions leading to these failures have been described as caused by a rapid rise in pore-water pressure as a result of rainwa- ter infiltration, the important factors that influence the initiation of slope failures have not been adequately clari- fied. To investigate these factors, a series of laboratory experiments was conducted on model sandy slopes to determine the initiation process of rainfall-induced slope failure. In the tests, failures were induced in small-scale model slopes either by water percolation from the side upslope or by artificial rain falling on top of the slope. Besides monitoring pore-water pressure, changes in soil moisture contents and ground deformation were mea- sured. Test results showed that slope failure was always induced when the soil moisture content within a certain region near the toe of the slope reached nearly full saturation, even though other parts of the sliding mass were still in a partially saturated state. In addition, minute deformations along the slope were shown to precede failure. The findings presented here show that by monitoring the soil moisture content of slopes and performing displace- ment measurements, it is possible to predict the occurrence of rainfall-induced slope failure.
Relative frequency and pattern of usage of stock teeth in removable partial dentures in a clinical setting in Nigeria

Aims: The current study was designed to determine the frequency of usage of acrylic stock teeth in RPDs using variables such as age, gender, jaw quadrants and jaws respectively. Methods: This random retrospective study reviewed the laboratory cards of 2,266 adult patients who requested for RPDs from the Dental Centre of Lagos State University Teaching Hospital, Ikeja, Lagos, Nigeria. Data on the frequency of usage of stock teeth relative to the sides of each jaw as well as both jaws, age and gender were recorded and analysed. Results: There were 2,774 acrylic partial dentures supplied during the period of study. Males (67.7%) used upper dentures compared to females (59.4%); and more females (40.6%) requested for lower dentures as against 32.3% males. A decline in the number of teeth replaced was seen progressively towards the posterior region of each jaw. No marked difference was seen between the distribution of teeth provided for the right and left sides of each jaw. There were more acrylic stock teeth demanded for the upper jaw compared to the lower jaw. Conclusion: The request for RPDs was Olugbenga Adetokunbo Adenuga-Taiwo1, Adolphus Odogun Loto2, Adenike Ololade Awotile1, Ifeoma Nkiruka Menakaya1 Affiliation: 1Lecturer 1, Department of Restorative Dentistry, College of Medicine Lagos State University, Ikeja, Lagos state, Nigeria; 2Senior Lecturer, Department of Restorative Dentistry, College of Medicine Lagos State University, Ikeja, Lagos state, Nigeria.

Knowledge, Practice and Associated Factors of Adult Intensive Care Nurses’ on Prevention of Ventilator Associated Pneumonia in Addis Ababa Public Hospitals, Addis Ababa, Ethiopia

Pneumonia is amongst the most leading cause of death in developing world where Ventilator Associated Pneumonia (VAP) is common among patients on mechanical ventilation/ intubation post hospitalization, and it is 6-20 times higher among patients in critical / intensive care units. Multiple factors were identified in different literatures for its occurrences. Poor nurses’ knowledge and practices were repetitively reported from public hospitals in Ethiopia. The objective of this study is to assess knowledge, practice and associated factors of Adult Intensive Care nurses’ on prevention of Ventilator Associated Pneumonia (VAP) in selected Hospitals in Addis Ababa, Ethiopia. A Facility based cross-sectional and observational study was conducted on 129 Adult Intensive Care nurses using self-administered questionnaire and observational checklist. The study shows that, Out of 129 respondents, 78 (60.5%) were females, 73 (56.6%) had diploma. There was a significant difference in knowledge between trained and non-trained adult intensive care nurses as found (p value = 0.04) and as increased educational level (p value = 0.021). Significant difference in practice was found between ICU nurses who had ICU training (p value = 0.038) and between nurses with different years of working experiences (p value = 0.033). Thus, the study reveals that majority of nurses working in the Adult Intensive Care Units had inadequate knowledge and practice.
