Spatiotemporal dynamics of greenhouse gases emissions from livestock and poultry in Beijing area during 1978—2009

Livestock production,especially its intensification around metropolitan areas,has contributed immensely to global warming.The estimation and analysis of spatial and temporal patterns of greenhouse gas emissions from livestock and poultry production were critical for the formulation of mitigation and adaptation strategies of national agricultural sectors.To investigate greenhouse gas emissions from enteric fermentation and manure management of livestock and poultry industry in Beijing area,emissions of methane and nitrous oxide during 1978—2009 were estimated based on regional livestock statistics.The study used the emission factor method recommended by the 2006 IPCC Guidelines and specific emphasis was placed on the trends and spatial distributions of the emissions.The results showed that livestock and poultry emissions in Beijing area started increasing at the early 1990s and peaked in 2004,with an average annual growth rate of 2%. This trend was similar to the increase in livestock and poultry population in Beijing area.Among the emissions,enteric fermentation methane was the most significant,with annual average emission of 0.4 Tg CO2-eq.Cattle was the main contributor to enteric fermentation methane emission,accounting for 54%,followed by swine and sheep.The annual average emissions of methane and nitrous oxide from manure management were 0.2 Tg CO2-eq and 0.3 Tg CO2-eq,respectively.The emissions were mainly from swine,respectively accounting for 73% and 46% of the emitted methane and nitrous oxide.Increase in methane indicated the intensification of livestock and poultry industry in Beijing area during 1978—2009.CR4(industry concentration index) increased progressively from 1978 to 2009,indicating unceasing enhancement of the intensity of livestock industry in Beijing area.The emissions were mainly from Shunyi,Daxing,Miyun and Tongzhou Districts.The estimated livestock methane and nitrous oxide emissions in Beijing area for 1978—2009 was consistent with the linear growth model.Although an arduous task,it was urgent for the Beijing livestock industry to adopt efficient reduction strategies of greenhouse gases emission.

Apotosis body was observed by using transmission electron microscope.DNA ladder was detected in electrophoresis.Cell apoptosis rate increased from 3.72% to 23.37% and G 2 phase rate increased from 0.88% to 4.13%. Conclusion:sCT could inhibit human breast cancer cells by inducing apoptosis as well as regulating cell cycle distribution.
PARAMETERIZATIONS OF THE VON BERTALANFFY MODEL FOR DESCRIPTION OF GROWTH CURVES

The growth curves of animals, in general, have an “S” shape, also known as sigmoidal curves. This type of curve is well fitted by nonlinear regression models, including von Bertalanffy’s model, which has been widely applied in several areas, being presented in literature through different parameterizations, which in practice, can complicate its understanding, affect nonlinearity measures and inferences about parameters. To quantify the nonlinearity present in a Bates and Watts model, a geometric concept of curvature has been used. The aim of this work was to analytically develop three parameterizations of the von Bertalanffy’s nonlinear model referring to its nonlinearity, implications for inferences and to establish relationships between parameters in the different ways of expressing the models. These parameterizations were adjusted to the growth data of sheep. For each parameterization, the intrinsic and parametric curvature measurements described by Bates and Watts were calculated. The parameterization choice affects nonlinearity measures, consequently, influences the reliability and inferences about estimated parameters. The forms most used in literature showed the greatest deviations from linearity, showing the importance of analyzing these measures in any growth curve study. Parameterization should be used in which the b estimate represents the abscissa of the inflection point, as it presents minor linearity deviations and direct biological interpretation for all parameters. 1Universidade Federal de Lavras UFLA, Departamento de Estat́ıstica, Programa de PósGraduação em Estat́ıstica e Experimentação Agropecuária, Caixa Postal 3037, CEP: 37200900, Lavras, MG, Brasil.

THE RAINWATER HARVESTING TECHNOLOGY APPROACH FOR DRYLAND AGRICULTURE IN SEMIARID LOESS PLATEAU OF CHINA

The traditional watersoilconserving agriculture has been developed for several decades.However,its regulative roles in water,fertility and temperature,were very limited.We think that the practicable approach is to harvest and stored rainwater artificially,and to supply limited irrigation at the key stage in crop development.This paper reviewed the research progress in rainwaterharvesting technology applied in crop production.It is suggested that this technology will become one of the major directions of dryland agriculture in Northwest China.
List of figures and tables

Recent research in video retrieval has focused on automated , highlevel feature indexing on shots or frames. One of the most impo rtant application of such indexing is to support precise video retrieval. We re po t on extensions of this semantic indexing on news video retrieval. First, we util ize extensive query analysis to relate various high-level features and query te rms by matching the textual description and context in a time-dependent manner. Se cond, we introduce a framework to effectively fuse the relation weights with the detectors’ confidence scores. This results in individual high level feature s that are weighted on a per-query basis. Tests on the TRECVID 2005 dataset shows that t he bove two enhancements yield significant improvement in performance over a corresponding state-of-the-art video retrieval baseline.
Analysis of rectangular waveguide partially loaded with lossy dielectric

An analysis is presented for rectangular waveguides with partial dielectric loading in the H-plane. Accurate results are given for attenuation and phase constant for lossy dielectric, using both exact and perturbation approaches. Particular attention is paid to the abnormal situation where attenuation can be greater for partial loading than for complete loading by the same lossy material. This abnormality was reported by Bui and Gagne but discounted by them as being mathematically spurious. By contrast, in this paper an exact theory has been used and the abnormality is shown to be genuine, and due to the hybrid mode redistribution of fields.
MEASUREMENT OF E-SERVICE QUALITY: AN EMPIRICAL STUDY ON ONLINE RAILWAY TICKET RESERVATION WEBSITE SERVICE

With the rapid developments in the sphere of information technology, internet has become a powerful tool in business. As a result e-service quality has become critical for companies to attract and retain the customers in this virtual environment. The main aim of this article is to provide insight into the dimensions of e-service with an empirical study on online railway ticket reservation website service. Primary data was collected from the online users of Indian Railways in India with the help of a 21 item instrument which is devised on the basis of thorough review of literature. To extract the various dimensions of e-service quality factor analysis is performed via SPSS 16. The results bring out four core e-service quality dimensions namely: Efficiency, Responsiveness, Privacy and security and Reliability. Surprisingly, privacy and security dimension scores the highest score of 3.85. It indicates that the users do not recognize considerable risk in online environment of e-service stemming from the possibility of misuse of their financial information and personal information. It is followed by efficiency, responsiveness and reliability with mean scores of 3.72, 3.43 and 3.19 respectively. Managers should focus on providing superior technical function of the website without any operating problems and 24 hours access to e-service. The reason behind is that if the users cannot use e-service when they need, they will immediately switch to some other e-service. Directions for further research on e-service quality are offered. Managerial implications stemming from the empirical findings about e-service quality are also discussed.
Effects of Bio-fermented Feed from Cottonseed Meal on Apparent Digestibility,Plasma Biochemical and Immune Indices in Yellow-feather Broilers

Ninety six 45-day-age healthy yellow-feather broilers were randomly divided into 4 groups according to similar weight(male∶female=1∶1) ,and each group had 4 replicates of 6 broilers. This experiment was conducted to study the effects of bio-fermented feed from cottonseed meal on apparent digestibility,plasma biochemical and immune indices in yellow-feather broilers. Group Ⅰ was as control group adding 6% base fermented substrate in basal diet;groups Ⅱ,Ⅲ and Ⅳ as treat groups were added 6% of Candida tropicalis ZD-3(CT) fermented feed,Saccharomyces cerevisiae(SC) fermented feed and compound fermented feed of CT and SC,respectively. The results showed as follows:compared with control group,the apparent digestibility of dry matter and crude protein increased significantly(P0.05);whereas,there was no significant difference in digestibility of ether extract among treatment group(P0.05);digestibility of calcium incresaed significantly in group Ⅱ(P0.05) and crude ash,phosphorus digestibility in group Ⅲ,Ⅳ were higher significantly than group Ⅰ(P0.05) . The albumin and calcium content of plasma in treatment groups were increased(P0.05) and total protein content of plasma in group Ⅱ was higher than group Ⅲ and lower than group Ⅳ. Total plasma cholesterol was lower than group Ⅰ but group Ⅳ. Triglycerides,phosphorus were reduced in all groups except group Ⅳ. Treatment groups were improved than control group.
Short-term grazing exclusion impacts using brush packs on soil and grass layers in degraded communal rangelands of semi-arid South Africa and implications for restoration and pasture utilization

Brush packs from very thorny tree branches were used to simulate grazing exclosures to measure differences in herbaceous vegetation and soil characteristics over 2 years on small ungrazed plots and large continuously grazed communal rangelands on 3 semi-arid soil types [shallow, red stony ground (SRSG); shallow, dark sandy loam (SDSL); and deep, dark clay-loam (DCL)]. Pasture presentation yields within exclosures exceeded those on continuously grazed areas for all soil types by: 98% (SRSG), 128% (SDSL) and 152% (DCL). Herbage samples harvested from the exclosures contained higher acid detergent fiber (P≤0.001) and acid detergent lignin (P<0.05) concentrations than those from the grazed areas. In SRSG and SDSL soils, herbage samples harvested from the exclosures were deficient in phosphorus (P) for all livestock species. Depending on soil type(s), soil magnesium, organic carbon, nitrogen, P and manganese concentrations were significantly higher within exclosures than in continuously grazed areas (P≤0.05). Any response from nutrients supplied by leaf drop from the brush packs could not be separated from response due to absence of grazing, and this deserves further investigation. Our results indicate that grazing exclusion for short periods (2 years) on these semi-arid rangelands allowed pastures to produce significant growth, demonstrating that pastures were still productive. Our experiences highlighted the difficulties in erecting and retaining conventional fences to exclude livestock from given areas because of theft. Grazing immediately after vegetation recovery may necessitate judicious nutritional intervention with protein, energy and mineral supplementation to get effective utilization of the available forage.
Simplexity, almost nothing, but human expanded abilities

In the context of the fourth industrial revolution, not all regions have the same access to technology for project development. These technological limitations do not necessarily result in worst projects and, on the contrary, can stimulate creativity and human intervention to overcome these shortcomings. We report here the design of a small pavilion with scarce budget and an ambitious goal to qualify a space through tactical urbanism. We develop the project in a multidisciplinary partnership between academy and industry, designing, manufacturing and assembling Tornado Pavilion, a complex structure using combined HIGH-LOW technologies, combining visual programming with analog manufacture and assembly. The design strategy uses SIMPLEXITY with ruled surfaces strategy to achieve a complex geometry. Due to the lack of automated mechanical cutting or assembly, we used human expanded abilities for the construction; instead of a swarm of robots, we had a motivated and synchronized swarm of students. The pavilion became a reference for local population that adopted it. This process thus shows that less or almost nothing (Sola-Morales 1995), need not to be boring (Venturi 1966) but less can be much more (Kolarevic 2017).
Data Deduplication using Even or Odd Block (EOB) Checking Algorithm in Hybrid Cloud

- Data deduplication is one of important data compression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. Data deduplication is a capacity optimization technology that is being used to dramatically improve storage efficiency. IT managers and executives face explosive data growth, driving up costs of storage for backup and disaster recovery (DR). For this reason, data deduplication is regarded as the next evolutionary step in backup technology and a “must-have” for organizations that wish to remain competitive by operating as efficiently as possible. Data deduplication maximizes storage utilization while allowing IT to retain more near line backup data for a longer time. This tremendously improves the efficiency of disk-based backup, changing the way data is protected. In general, data deduplication compares new data with existing data from previous backup or archiving jobs, and eliminates the redundancies. Advantages include improved storage efficiency and cost savings, as well as bandwidth minimization for less-expensive and faster offsite replication of backup data. We use Even or Odd Block (EOB) checking algorithm and metadata manager MM for data deduplication in hybrid cloud as it reduce the time instead of comparing all blocks in the file.
Abstract 290: Proliferation of Cardiac Fibroblasts Defines Early Stages of Genetic Dilated Cardiomyopathy and Precedes Myocardial Metabolic Derangement

The complex molecular networks underpinning DCM remain poorly understood. To study distinct pathways and networks in the longitudinal development of DCM we performed RNAseq on LV tissue from mice carrying a human DCM mutation in phospholamban (PLNR9C/+) before phenotype onset (pre-DCM), with DCM, and during overt heart failure (HF), and also on isolated myocytes and non-myocytes from DCM hearts. PLNR9C/+ mice show progressive fibrosis (20% vs. 1% control, p=6x10−33; n=3) associated with proliferation of cardiac non-myocytes (33% increase over control, p=6x10−4; n=3). Consistent with this, cardiac non-myocytes have upregulated gene expression and pathways, while these are generally downregulated in myocytes. Non-myocytes were enriched in fibrosis, inflammation, and cell remodeling pathways, from pre-DCM to HF. In contrast, myocytes were enriched for metabolic pathways only with overt DCM and HF. Myocytes showed profound derangement of oxidative phosphorylation with DCM (p=2.5x10−41; 44% (53/120) of pathway.
Cell type and cortex-specific RNA editing in single human neurons informs neuropsychiatric disorders

Conversion of adenosine to inosine in RNA by ADAR enzymes occurs at thousands of sites in the human transcriptome, and is essential for healthy brain development. This process, known as ‘RNA editing’, is dysregulated in many neuropsychiatric diseases, but is little understood at the level of individual neurons. We examined full-length nuclear transcriptomes of 3,055 neurons from six cortical regions of a neurotypical post-mortem female donor and identified 40,861 high-confidence edited sites. The majority of sites were located within Alu repeats in introns or 3’ UTRs, and were present in previously published RNA editing databases. We identified 15,784 putative novel RNA editing sites, 30% of which were also detectable in independently generated neuronal transcriptomes from unrelated donors. The strongest correlates of global editing rates were expression levels of small nucleolar RNAs from the SNORD115 and SNORD116 cluster (15q11), known to modulate serotonin receptor processing and to colocalize with ADAR2, one of three known RNA editing enzymes in humans. As expected, expression of DNA and RNA binding proteins were negatively associated with editing. We present evidence for dysregulated RNA editing in six rare genetic conditions; and report 117 differentially edited sites between cortical regions and neuronal subtypes. These results provide spatial and neurophenotypic context for 1,871 and 998 sites that are differentially edited in the brains of schizophrenic and autistic patients respectively, and a reference for future studies of RNA editing in single brain cells from these cohorts.
CloakLoRa: A Covert Channel over LoRa PHY

This paper describes our design and implementation of a covert channel over LoRa physical layer (PHY). LoRa adopts a unique modulation scheme (chirp spread spectrum (CSS)) to enable long range communication at low-power consumption. CSS uses the initial frequencies of LoRa chirps to differentiate LoRa symbols, while simply ignoring other RF parameters (e.g., amplitude and phase). Our study reveals that the LoRa physical layer leaves sufficient room to build a covert channel by embedding covert information with a modulation scheme orthogonal to CSS. To demonstrate the feasibility of building a covert channel, we implement CloakLoRa. CloakLoRa embeds covert information into a regular LoRa packet by modulating the amplitudes of LoRa chirps while keeping the frequency intact. As amplitude modulation is orthogonal to CSS, a regular LoRa node receives the LoRa packet as if no secret information is embedded into the packet. Such an embedding method is transparent to all security mechanisms at upper layers in current LoRaWAN. As such, an attacker can create an amplitude modulated covert channel over LoRa without being detected by current LoRaWAN security mechanism. We conduct comprehensive evaluations with COTS LoRa nodes and receive-only software defined radios and experiment results show that CloakLoRa can send covert information over 250m.
Cost Over-Run in Civil Works: A Case-Study of Engineering, Procurement and Construction (EPC) Gas Depot Construction Projects in Nigeria

Engineering, procurement and Construction (EPC) projects in the oil and gas sector of Nigeria are under-researched. This leaves investors with little or no guide on the cost-overrun risks of oil and gas depot projects. Using the qualitative case study research technique, this study investigated cost overrun in the civil works of a petroleum products depot project in Lagos, Nigeria. The objectives were to ascertain the reasons for cost overrun and the areas of substantial cost overrun in the project. It was found that except for the cost of construction of “gantry” which was under-measured as a result of use of a wrong method of costing, the rest of the major facilities experienced cost overrun with a cumulative difference of 106%. It was also discovered that the cost overruns mainly originated from design and construction activities. The study recommends the timely engagement of consultants to review the conceptual designs of contractors and monitor the activities of EPC contractors for oil and gas depot projects on behalf of clients. Such consultants should not, however, have powers to control the contractors. As much as possible, parties to EPC contracts should use standard conditions of contract that will better reflect their intentions rather than contrive bespoke conditions.
A Deformation Mechanism Map of Ice

Abstract A deformation mechanism map for pure polycrystalline ice of 2 mm grain diameter is constructed, New sub-regions in the dislocation glide region are proposed: dislocation glide with crack formation, dislocation creep, and fracture at high stresses above about 1 MPa. The boundary between the dislocation creep and DGC regions is determined by the onset of cleavage cracks due to piled-up dislocations near grain boundaries. The fracture region is that area of the map where fracture occurs readily when the ice is subjected to a rapid deformation rate exceeding 10-3 s-1. Experimental results of the stress dependence of the compressive deformation rate of polycrystalline ice are compared with the map. The effect of changes in the creep activation energy near the melting point is discussed together with those of other factors.
THE 5 STUDENT SYMPOSIUM ON MECHANICAL AND MANUFACTURING ENGINEERING Parameter study and a numerical model of mechanical roller expansion of tube-tubesheet joint

The tube-tubesheet joint by roller expansion is commonly used in the heat exchanger production industry. This process has quality issues, due to over or under expansion of the tubes. This paper focuses on determining the parameters’ influence on the joint’s quality. A numerical model is made using LS-DYNA, where the rotation of the rollers is modelled to simulate the step-wise deformation of the tube. The model is made in 3D, with an assumption of plane strain for a section of the tube and tubesheet. Experiments are conducted and evaluated using pull-out force as a quality measurement. A multi linear regression analysis is conducted on the collected data from the experiments. This is done in order to investigate the four main parameters’ influence on the joint’s quality: Torque, rolling depth, clearance and tubesheet hole diameter. It was concluded that clearance has no effect on the quality of the joint, where torque and rolling depth have proven to be of significance. Furthermore, from the numerical model it was discovered that highly fluctuating hoop stresses result in the wave like plastic strain distribution throughout the tube’s thickness.
