The effects of nonstructural carbohydrate and dietary protein on feed intake, ruminal fermentation and cows performance

Providing high levels of nonstructural carbohydrate (NSC) in ruminant diets tends to change fermentation lowering rumen pH and reduce milk fat content. Balancing readily available N and energy-yielding carbohydrate may enhance microbial growth rate, alter fermentation and fibre digestion in the rumen, which subsequently may have an impact on nutrient supply to host animal. Therefore, the objective of this study was to measure the effects of dietary nonstructural carbohydrate and protein level on intake, ruminal fermentation and performance of dairy cows using cassava as main energy source.Forty-two crossbred cows (60.9% Holstein Friesian, 26.8% Danish Red, 10.2% Red Sindi) at a mean of 71.0 ± 28.5 days in milk (DIM) with a pre-treatment milk yield of 13.2 ± 2.2 kg/d and a BW 373.1 ± 33.4 kg. Cows were tethered in stalls and randomly allocated to receive one of six total mixed ration (TMR) on ad-lib basis. Isocaloric diets (ME 11.2 MJ/kg) were formulated to contain Ruzi grass silage and a concentrate mix (20:80 ratio) containing NSC (30, 35, 40%) in combination with 2 levels of crude protein (15.7, 18.4%).
Pola pengasuhan 1.000 hari pertama kehidupan dan status gizi anak bawah dua tahun (baduta) di Kota Medan

Health problems in the first 1000 days of life have short- and long-term consequences for children under the age of two years. This study examines how the childcare pattern during the first 1000 days of life affects the nutrition status of children under two in Medan City. This study is conducted by using mixed methods approach. A survey was performed to collect quantitative data of 400 households in 20 urban villages, whereas in-depth interviews and focus group discussions were conducted to collect qualitative data. In this study, childcare during the first 1000 days of life includes colostrum feeding, early initiation of breastfeeding, exclusive breastfeeding, and complementary feeding practices. The study’s findings show that mothers’ education level is significantly associated to their knowledge of colostrum's benefit. Support from health providers and room-in policy needs to be improved to increase early initiation breastfeeding and exclusive breastfeeding. Additionally, mothers have even more variety of complementary feeding for children aged 6–24 months due to cultural practices and tradition. Thus, improving children under two’s nutrition status requires comprehensive health promotion by considering sociocultural factors and evaluating the implementation of policies that support early initiation breastfeeding and exclusive breastfeeding practices.
Comparison of Structural Properties between Monopile and Tripod Offshore Wind-Turbine Support Structures

Offshore wind power provides a new kind of green energy. This paper presents a comparison study on the structural properties of monopile and tripod wind-turbine support structures, which are used extensively in offshore wind farms. Both structures have the same upper tower, but different lower structures, one with a monopile and the other with a tripod. Static, fatigue, and modal analyses indicate that both the tripod and monopile structures are feasible in the field, but that the tripod structure is superior to the monopile structure. Static analysis reveals that the location of maximum stress in the monopile structure is different from that in the tripod structure, and that the tripod structure shows higher stiffness and greater stress-control capacity than the monopile structure. Fatigue analysis indicates that the tripod structure has a longer lifetime than the monopile structure. Modal analysis indicates that the two structures exhibit large differences in their natural frequencies. Unlike the monopile structure, the third and first modes both have a substantial influence on the dynamic response of the tripod structure.
Rapid high-confidence intelligent interior mapping

This paper presents preliminary results on an intelligent mapping capability that generates high-confidence layouts of building interiors from limited exterior and interior structural observables. Such a capability could provide critical support to intelligence gathering and/or life-saving operations in the military, law enforcement, disaster response, and commercial sectors where rapid understanding of unknown interior layouts is required to save lives, maintain covertness, or minimize costs. The fundamental approach relies on an intelligent rule-based inferencing process which operates on limited structural observables. The rules are based on geo-specific design practices and building codes. The mapping capability has been demonstrated experimentally in a test-case building structure using a set of imaging sensors to scan the environment. Data was gathered at sparse locations within the building to represent a real-world rapid exploration scenario. Preliminary results show that this capability can successfully generate high-confidence interior layouts from limited structural observables. It is envisioned that this intelligent mapping capability could be integrated on unmanned ground vehicle platforms or in human-borne (soldier, SWAT, urban search-and-rescue personnel) systems.
Region-Based Convolutional Neural Network for Wind Turbine Wake Characterization in Complex Terrain

We present a proof of concept of wind turbine wake identification and characterization using a region-based convolutional neural network (CNN) applied to lidar arc scan images taken at a wind farm in complex terrain. We show that the CNN successfully identifies and characterizes wakes in scans with varying resolutions and geometries, and can capture wake characteristics in spatially heterogeneous fields resulting from data quality control procedures and complex background flow fields. The geometry, spatial extent and locations of wakes and wake fragments exhibit close accord with results from visual inspection. The model exhibits a 95% success rate in identifying wakes when they are present in scans and characterizing their shape. To test model robustness to varying image quality, we reduced the scan density to half the original resolution through down-sampling range gates. This causes a reduction in skill, yet 92% of wakes are still successfully identified. When grouping scans by meteorological conditions and utilizing the CNN for wake characterization under full and half resolution, wake characteristics are consistent with a priori expectations for wake behavior in different inflow and stability conditions.
A Novel Whole Yeast-Based Subunit Oral Vaccine Against Eimeria tenella in Chickens

Cheap, easy-to-produce oral vaccines are needed for control of coccidiosis in chickens to reduce the impact of this disease on welfare and economic performance. Saccharomyces cerevisiae yeast expressing three Eimeria tenella antigens were developed and delivered as heat-killed, freeze-dried whole yeast oral vaccines to chickens in four separate studies. After vaccination, E. tenella replication was reduced following low dose challenge (250 oocysts) in Hy-Line Brown layer chickens (p<0.01). Similarly, caecal lesion score was reduced in Hy-Line Brown layer chickens vaccinated using a mixture of S. cerevisiae expressing EtAMA1, EtIMP1 and EtMIC3 following pathogenic-level challenge (4,000 E. tenella oocysts; p<0.01). Mean body weight gain post-challenge with 15,000 E. tenella oocysts was significantly increased in vaccinated Cobb500 broiler chickens compared to mock-vaccinated controls (p<0.01). Thus, inactivated recombinant yeast vaccines offer cost-effective and scalable opportunities for control of coccidiosis, with relevance to broiler production and chickens reared in low-and middle-income countries (LMICs).

Secondly, by using the setting values from a bulldozer, simulation work is implemented, and parameters of the hybrid power system are matched, and finally, based on MATLAB/Simulink ,dynamic models for the dual-motor-driving hybrid power system is established, and the simulation results are discussed. Simulation results demonstrate the validity of the hybrid power system model and the matching of the parameters of the hybrid power system is reasonable.
The Fabrication and Test of a Phase-Change Micropump

This paper presents the fabrication and test of a phase-change type micropump with two aluminum flap valves. This micropump consists of a pair of Al flap valves and a phase-change type actuator. The actuator is composed of a heater, a silicone rubber diaphragm and a working fluid chamber. The diaphragm is actuated by the vaporization and the condensation of the working fluid. The micropump is fabricated by the anisotropic etching, the boron diffusion and the metal evaporation. The dimension of the micropump is 8.5 mm × 5 mm × 1.7 mm. The forward and the backward flow characteristics of the flap valve illustrate the appropriateness as a check valve. Also, the flow rate of the micropump is measured. When the square wave input voltage of 10 V is applied to the heater, the maximum flow rate of the micropump is 6.1 μl/min at 0.5 Hz and the duty ratio of 60% for zero pressure difference.
Yield learning model for integrated circuit package assembly

This paper describes a model for yield learning in integrated circuit package assembly. This model provides a management tool for yield projection, resource allocation and what-if analysis. An Excel spreadsheet-based model was developed using a series of case studies of TCP, PQFP, CBGA, and PBGA packages entering manufacturing. The factors that affect yield learning rates (e.g. process complexity, production volumes, personnel experience) were identified and models successfully built to predict the yield ramp for each product. We found that a common model with a common set of factors and the same relative factor importance could be used for all package technologies.
Automation of colonoscopy. II. Visual control aspects

During a conventional colonoscopy examination, the endoscopist watches a video monitor that displays the real-time images being captured by a CCD camera at the distal end of the colonoscope. Some researchers believe that a computer can be used to interpret these images and be trained to recognize and correctly locate the position of the lumen. This information will then be processed and used to control and maneuver the colonoscope automatically into the colon. It can also be used to identify abnormalities of the large intestine. This article presents a literature survey that gives a critical review of research in the area of visual control in automated colonoscopy. It is concluded that, generally, the idea of using computer vision to aid in the automation of colonoscopy is meritorious. However, it is important for one to realize the vast differences in physical attributes of the colon. No two colons are similar. Even within the same colon, one section may portray very different characteristics from another. Since technology is not yet at the stage where computers can think in the same way as do human beings, computerized visual control in colonoscopy may not be realized for some time.
Use of frequency and transmitter location diversities for ambiguity suppression in synthetic aperture sonar systems

Three synthetic aperture sonar designs, which aim at doubling the mapping rate by use of transmitter location and frequency diversities, are assessed. It is shown that neither allow better ambiguity suppression than the conventional design. Two new designs, M. A. Pinto (1996), which achieve this goal are presented as well as an extension to bathymetric imaging. An application to deep ocean imaging is proposed.
Addicted to cruises? Key drivers of cruise ship loyalty behavior through an e-WOM approach

Purpose This paper aims to identify the drivers that explain loyalty behavior in cruise tourism with the aim of achieving a better understanding of repeat cruisers’ intentions to sail on the same ship or on another ship belonging to the same cruise line or cruise corporation. Design/methodology/approach Based on over 150,000 online reviews about their satisfaction and experience posted by cruisers using so-called electronic Word of Mouth (e-WOM), the authors apply both a graphic and an econometric technique through input-output circular plots and discrete choice models. Findings The main results show that cruisers’ behavior is influenced by multiple onboard attributes, such as the service crew, entertainment options, type of cabin, some characteristics of the ship (age, capacity) and the cruise line (Premium-Luxury versus mainstream), and, specifically, the quality and variety of the gastronomic experience. Practical implications The results highlight that repeats cruisers are predominantly linked to a cruise company or a cruise corporation rather than a particular ship. This result provides information on the moderators that can influence the customers’ repetition behavior, which might be useful for planning revenue management and extending knowledge on hospitality loyalty in general and in the cruise industry in particular, specifically under the current uncertainty due to the COVID-19 pandemic. Originality/value The previous literature has essentially examined revisit intentions in the cruise market from a qualitative approach and the authors have found no study to date that has simultaneously addressed this issue in three dimensions, namely, ship, cruise line and cruise corporation. The research fills this gap by determining the reasons why passengers would repeat a cruise either on the same ship, with the same cruise line or the same cruise corporation based on previous experience.

Peripheral blood eosinophils priming and in vitro vascular endothelial growth factor stimulation in asthmatics

Introduction Asthma is a complex airway disease with heterogeneity in molecular pathways. Hypersecretion of many cytokines (e.g. vascular endothelial growth factor – VEGF), inflammatory cells infiltration (e.g. eosinophils) and different genetic factors (e.g. gene polymorphism) might be responsible for physiological and pathological changes in the course of this chronic disease. Aim To reveal the possible expression of activation marker CD69 on eosinophils unstimulated and stimulated by VEGF in patients with asthma. Additionally, the influence of a genetic factor (del18 genotype at -2549 -2567 position in the promoter of the VEGF gene) was considered. Material and methods The study involved 122 participants (82 patients with asthma and 40 healthy controls). CD69 expression on peripheral blood eosinophils was detected by flow cytometry without exogenous stimulation and after in vitro stimulation with VEGF. Genotyping for VEGF-promoter region was performed using the polymerase chain reaction method. Results CD69 was strongly presented (p < 0.05) on unstimulated eosinophils of patients with asthma and del18 genotype in the promoter of the VEGF gene. Stimulation of peripheral eosinophils with VEGF did not induce CD69 expression in a dose-dependent manner. Conclusions Our results may suggest the potential contribution of the VEGF gene polymorphism to the spontaneous increase of eosinophils activity (priming) in patients with asthma. In addition, the results show that VEGF is unlikely to significantly activate eosinophils in asthmatics.
Crashworthiness Evaluation Using Integrated Vehicle and Occupant Finite Element Models

Abstract Recent development in computer hardware technology and software advancement has made it possible to develop large and detailed finite element models, which include vehicle structures, interior, seats, airbags, and hybrid-III dummies, for crashworthiness evaluation. This paper presents some recent effort of developing an approach for crashworthiness using integrated vehicle structural, interior, occupant, and airbag finite element models. A case study using integrated finite element models of vehicle structure and interior, airbag, seats, and hybrid-III dummy is discussed to demonstrate the potential benefit of the integrated simulation and analysis approach. This new integrated approach will further improve the engineering practice with cost saving in engineering resources and producing more accurate and consistent analysis results.
Strategie Marketing Practices: Their contribution to the competitive success of medium-sized manufacturing firms in New Zealand

Abstract This article examines the contribution of selected ‘textbook’ strategic marketing practices to the competitive success of medium sized New Zealand manufacturing firms as well as the extent of their overall adoption within this group of firms. Data was collected by mail survey. A total of 213 usable questionnaires were received from companies employing between 20 and 100 people. Data analysis was conducted using SPSS. The results show that although most of the basic strategic marketing practices typically advocated in the mainstream academic and prescriptive literature clearly differentiate the higher performing firms from their lower performing counterparts, for many medium sized manufacturing firms in New Zealand there still remains much to be done if they are to fully embrace strategic marketing. One limitation is the unknown extent to which the sample is truly representative of the population under scrutiny. Also, differences in the interpretation of certain questions in the questionnaire cannot be ruled out.
Monitoring and Predicting Freeway Travel Time Reliability: Using Width and Skew of Day-to-Day Travel Time Distribution

Generally, the day-to-day variability of route travel times on, for example, freeway corridors is considered closely related to the reliability of a road network. The more that travel times on route r are dispersed in a particular time-of-day (TOD) and day-of-week (DOW) period, the more unreliable travel times on route r are conceived to be. In the literature, many different aspects of the day-to-day travel time distribution have been proposed as indicators of reliability. Mean and variance do not provide much insight because those metrics tend to obscure important aspects of the distribution under specific circumstances. It is argued that both skew and width of this distribution are relevant indicators for unreliability; therefore, two reliability metrics are proposed. These metrics are based on three characteristic percentiles: the 10th, 50th, and 90th percentile for a given route and TOD-DOW period. High values of either metric indicate high travel time unreliability. However, the weight of each metric on travel time reliability may be application- or context-specific. The practical value of these particular metrics is that they can be used to construct so-called reliability maps, which not only visualize the unreliability of travel times for a given DOW-TOD period but also help identify DOW-TOD periods in which congestion will likely set in (or dissolve). That means identification of the uncertainty of start, end, and, hence, length of morning and afternoon peak hours. Combined with a long-term travel time prediction model, the metrics can be used to predict travel time (un)reliability. Finally, the metrics may be used in discrete choice models as explanatory variables for driver uncertainty.
Beveled monopole antenna with slot loaded semicircular like ground plane for UWB applications

A beveled monopole antenna for UWB communication systems is presented. It is fed by a 50‐Ω modified microstrip feedline. The impedance matching is improved using beveled patch, modified feedline, and semicircular like ground plane. The bandwidth is further enhanced by the excitation of an additional resonance at higher frequency due to the loading of ground plane with a pair of rectangular slots. The antenna is fabricated on a low cost FR‐4 epoxy substrate having size of 40 mm (Lsub) × 30 mm (Wsub) × 1.6 mm (h). A VSWR ratio of 7.1:1 is achieved for an impedance bandwidth of 2.4–17.1 GHz (14.7 GHz i.e., 150.77%). The antenna structure has omnidirectional radiation pattern and an average peak realized gain of 3.5 dB. The experimental and simulated results are found to be in good agreement. The designed antenna structure has wide bandwidth with a size comparable to those of earlier reported ones. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1289–1296, 2015
Passivity–Based Control of Photovoltaic Grid-Connected Inverter

Photovoltaic (PV) grid-connected system requires the inverter possesses excellent dynamic and static characteristics. In the view of the mathematical model of the inverter is nonlinear, we will adopt a kind of nonlinear control strategy called Passivity–Based Control (PBC). First we establish the standard Euler – Lagrange (EL) mode for inverter, then we also prove that this inverter is strictly passive. Based on passivity of inverter, we can redistribute the system energy, and adopt the approaches of injecting damping and decoupling to improve system performance. In this paper, we can control the active and reactive power of system to make system can fast track the PV array maximum power point, and possess the capacity of compensating the reactive power. Simulation results show that passivity-based control method can make the inverter possess better robustness and dynamic.
