Published: June 2019

AbstractLivestock productivity in Indonesia is categorized as low compared to the other countries, yet the local Indonesian cattle is potential to develop. This research aimed to describe the genetic variation and phylogenetic profile of Bali cattle compared to their ancestor, i.e.Bos javanicusbased on mitochondrial cytochrome b gene. This research was descriptive in which as many as 11 samples from Bali and 18 samples from Lombok were involved. The data, in term of sequencing results, were analyzed by using MEGA 4 version. The research results showed that the highest variation occurred in sample CL_8 (83 nucleotides), while the lowest one was shown by CB_7 (12 nucleotides). Meanwhile, the phylogenetic tree constructed presented that, genetically, Bali and Lombok cattle were categorized in seven big groups in which the closest genetic distance was between BL_1 andBos javanicus(0.061), whereas the farthest was the distance between BL_8 andBos javanicus(0.312). The results of this research can be utilized as the basic data for related fields to determine the most appropriate policies, particularly in managing local cattle breeding to obtain superior filial.

Published: June 2019

Abstract
Coffee is a favourite beverage worldwide, with all of its benefits. The taste and flavour of coffee depending on the chemical components of the coffee. And the presence of chemicals in the coffee ground depends on the original tree as well as on processing. In this report, some volatiles from ground and brewed coffee beans of Robusta, Arabica, and peaberry coffee beans were extracted to be described after chemical analysis. Mainly gas chromatography/mass spectrometry methods were the main spectroscopy utilized to obtain chemistry information that was taken from hot brewed coffees. The result showed that peaberry coffee beans were very rich in components compared to others. Arabica coffee beans also had stronger in taste and flavour compared to robusta as seen from the profile compositions of chloroform and n-hexane extracts. Better processing would also be suggested for each type of coffee beans.

Authors: Shi Tingting , Li Zhengming , Zhao Yidong 
Published: June 2019

Abstract
Estuary systems are complicated and closely related to humans. The understanding of estuary systems is important to scientific study and human develop. An investigation was conducted on 3rd November 2009 by RV Callista along the Itchen estuary of Southampton Water with the aim of determining spatial variability in physical water column structure, nutrients, chlorophyll and zooplankton of Southampton Water, and recognizing the links between them. The salinity and temperature values are relatively lower at surface upper estuary than that of deep lower estuary. Water stratification is observed around upper and mid estuary. The nutrient Si exhibits conservative behaviour with a linear relationship with salinity gradient, while P shows non-linear with salinity, which may indicate an addition bahaviour. Chlorophyll distributes high concentration at surface upper estuary and relatively uniform and low concentration at downriver area which is mainly due to light and nutrients factors. Water turbidity affects chlorophyll distribution by reducing light availability in the water column, while chlorophyll can in turn influence water turbidity. The abundance dominant species of the estuary are Copepoda and Appendicularia. The mid estuary has the highest zooplankton abundance, while the lower estuary has the most zooplankton groups. Zooplankton distribution is relative to food distribution, temperature, light and salinity profiles.

Authors: Kong Xiangming , Hao Zhenda , Yang Aili 
Published: June 2019

Abstract
Water resources management system has been a major concern since it gives necessities of human-living as well as promoting economic development. Therefore, how to establish valid and accurate water management schemes for water managers to satisfy the demands from water users, is of great significance. In this study, a modified spectral phase conjugation algorithm for quadratic programming (MCQP) is developed for water resources management systems. The model is detived by modifying the search direction within spectral phase conjugation algorithm. MCQP can efficiently solve nonlinearity in the objective function and linearity in the constraint which lead to complexes in water resources management systems. Results show that reasonable solutions have been obtained to support the rational development of water resources management. They can help water managers to identify desired policies under variou economic and environmental constraints. MCQP can be further applied to other resources management systems with mixed nonlinear and linear factors.

Through the comparative study of spatial and behavioral data, the paper expects to analyze the human-centered law and scientific response mechanism of the change of neighborhood space under the shared cycling mode to promote the development of the shared traffic in the city.
Effect of Steel Slag on Crystallization and Bending Strength of Glass Ceramics Based on Blast Furnace Slag
Authors: Shen X M , Zhao H T , Wu X R , Cao F B , Wang P , Li L S 
Published: June 2019

Abstract
The glass ceramics based on steel slag and blast furnace slag presented light-khaki color to deep-brown color with increasing content of steel slag. The major crystalline phase is gehlenite (Ca2Al2SiO7) with minor akermanite phase (Ca2MgSi2O7) for all the samples. Decreasing Al2O3 and increasing Fe2O3 in the samples increased glass viscosity, and decreasing SiO2 decreased the amount of liquid phase. Both the above effects result in the increasing optimum sintering temperature. The grain size and amount of crystalline phase were increased with content of steel slag. The bending strength of the samples first increases with content of steel slag up to a maximum 90 MPa, then decreases. The bulk density of the samples decreases with increasing content of steel slag, from 2.76 g/cm3 to 2.60 g/cm3, owing to lower content of glass phase during sintering process. The samples exhibit good chemical resistance, and the weight loss values in alkali are lower than those in acid. Therefore, the glass ceramics based on steel slag and blast furnace slag may have great potential for applications as building decorative materials, and it provides a promising way for the utilization of steel slag.
Penetration Level of Photovoltaic in Distribution Network Considering Voltage Constraint
Authors: Gang Wang , Shenghui Li , Aimin Liu , Yu Zhu 
Published: June 2019

Abstract
A large number of distributed PV connected to the distribution network may cause the voltage deviation of the grid to exceed the limit. Firstly, the calculation model of voltage loss caused by load under different distribution rules and the calculation model of voltage rise caused by photovoltaic are established. On the premise that the voltage deviation of the bus can reach the upper limit of the standard, the maximum allowable PV capacity of the line without overvoltage is derived. For a typical 10 kV line, the maximum PV permeability under the same distribution rule of PV and load and the voltage margin at the head of feeder without overvoltage are given. The results show that the overhead line can accommodate more PV capacity than the cable line, the voltage regulation of PV power can prevent overvoltage, and the bus voltage reduction can allow access to more PV capacity.

Authors: Zhang Jijun , Chen Zexiang , Wang Yan 
Published: June 2019

AbstractWe report a fabrication of urchin-like nanostructure NiCo2O4by hydrothermal method and followed by heating treatment method for cathode of asymmetric supercapacitors application. The sodium-p-styrenesulfonate (PSS) played a pivotal role in synthesizing the urchin-like nanostructure. The formation of NiCo2O4with urchin-like nanostructure was showed by the scanning electron microscope (SEM) and the crystalline structure was characterised by X-ray powder diffraction (XRD). The cyclic voltammetry curves exhibited a similar shape at all different scan rates, implying excellent rate capability. The galvanostatic current charge-discharge curves was also tested. The as-prepared NiCo2O4electrode exhibited the specific capacitance of 1168 F/g at a current density of 1 A/g (25 mA/cm2) and an excellent rate capability of 733 F/g at 16 A/g (400 mA/cm2). The cycle performance of the NiCo2O4sample under the current density of 4 A g−1is demonstrated which the value remained at 92.75 % of the maximum value.

Published: June 2019

AbstractBiological invasions have emerged as an eminent feature of global change, with substantial impacts on the environment and human livelihoods. Current research demonstrates that the numbers and impacts of alien species are rising unabatedly. At the same time, we lack a thorough understanding of potential future trajectories for the decades to come. With the recent establishment of comprehensive global databases, it is, for the first time, feasible to develop and quantify future scenarios of biological invasions. Therefore, we propose a conceptual framework for how to develop alien species scenarios for the twenty-first century and how to identify relevant steps and challenges along the way. The concept will be important to inform research, policy, stakeholders, and the general public. Furthermore, we call for the scientific community to join forces and to operationalize the framework for scenarios and models of biological invasions to develop an important baseline for understanding and managing future biological invasions.

Published: June 2019

Abstract

Background
Bacterial meningitis remains a major disease affecting children in Côte d’Ivoire. Thus, with support from the World Health Organization (WHO), Côte d’Ivoire has implemented pediatric bacterial meningitis (PBM) surveillance at 2 sentinel hospitals in Abidjan, targeting the main causes of PBM: Streptococcus pneumoniae (pneumococcus), Haemophilus influenzae, and Neisseria meningitidis (meningococcus). Herein we describe the epidemiological characteristics of PBM observed in Côte d’Ivoire during 2010–2016.

Methods
Cerebrospinal fluid (CSF) was collected from children aged <5 years admitted to the Abobo General Hospital or University Hospital Center Yopougon with suspected meningitis. Microbiology and polymerase chain reaction (PCR) techniques were used to detect the presence of pathogens in CSF. Where possible, serotyping/grouping was performed to determine the specific causative agents.

Results
Overall, 2762 cases of suspected meningitis were reported, with CSF from 39.2% (1083/2762) of patients analyzed at the WHO regional reference laboratory in The Gambia. In total, 82 (3.0% [82/2762]) CSF samples were positive for bacterial meningitis. Pneumococcus was the main pathogen responsible for PBM, accounting for 69.5% (52/82) of positive cases. Pneumococcal conjugate vaccine serotypes 5, 18C, 19F, and 6A/B were identified post–vaccine introduction. Emergence of H. influenzae nontypeable meningitis was observed after H. influenzae type b vaccine introduction.

Conclusions
Despite widespread use and high coverage of conjugate vaccines, pneumococcal vaccine serotypes and H. influenzae type b remain associated with bacterial meningitis among children aged <5 years in Côte d’Ivoire. This reinforces the need for enhanced surveillance for vaccine-preventable diseases to determine the prevalence of bacterial meningitis and vaccine impact across the country.
Size-dependent locomotory performance creates a behaviorally mediated prey size refuge in the marine snail Olivella semistriata: a study in the natural habitat
Authors: Veelenturf Callie A , Peters Winfried S 
Published: June 2019

Abstract
The effects of the variability of individual prey locomotory performance on the vulnerability to predation are poorly understood, partly because individual performance is difficult to determine in natural habitats. To gain insights into the role(s) of individual variation in predatory relationships, we study a convenient model system, the neotropical sandy beach gastropod Olivella semistriata and its main predator, the carnivorous snail Agaronia propatula. The largest size class of O. semistriata is known to be missing from A. propatula’s spectrum of subdued prey, although the predator regularly captures much larger individuals of other taxa. To resolve this conundrum, we analyzed predation attempts in the wild. While A. propatula attacked O. semistriata of all sizes, large prey specimens usually escaped by ‘sculling’, an accelerated, stepping mode of locomotion. Olivella semistriata performed sculling locomotion regardless of size, but sculling velocities determined in the natural environment increased strongly with size. Thus, growth in size as such does not establish a prey size refuge in which O. semistriata is safe from predation. Rather, a behaviorally mediated size refuge is created through the size-dependence of sculling performance. Taken together, this work presents a rare quantitative characterization in the natural habitat of the causal sequence from the size-dependence of individual performance, to the prey size-dependent outcome of predation attempts, to the size bias in the predator’s prey spectrum.
A case report: black oesophagus as a possible complication of transcatheter aortic valve implantation
Authors: Gonçalves Inês S , Bordalo e Sá Armando L , Fatela Narcisa , Canas da Silva Pedro 
Published: June 2019

Abstract

Background
The increasing number of transcatheter aortic valve implantation (TAVI) in the last few years has unveiled a unique set of events and complications that need prompt recognition and management in order to improve patient outcomes, often involving a multidisciplinary team.

Case summary
We present a case of a 86-year-old woman with symptomatic severe aortic stenosis that underwent a TAVI and, in the post-procedure period, presented with acute abundant haematemesis, haemodynamic instability, and haemoglobin drop. The diagnosis of acute necrotizing oesophagitis (ANE) was made by upper gastrointestinal endoscopy.

Discussion
Acute necrotizing oesophagitis is a rare entity caused usually by an ischaemic insult in the presence of predisposing factors; it has a high rate of complications and mortality. To the best of our knowledge, this is the first clinical case report to describe the occurrence of ANE as a possible complication of TAVI and is also an example of the importance of the multidisciplinary approach of these complex patients, which extends even beyond the concept of Heart Team.
A case report: mechanical tricuspid valve thrombosis necessitating cardiac surgery during pregnancy
Authors: Sathananthan Gnalini , Johal Niall , Grewal Jasmine 
Published: June 2019

Abstract

Background
Pregnant women with mechanical valves are considered a high-risk pregnancy. They carry an increased risk of both maternal and foetal complications. This includes maternal valve thrombosis, foetal embryopathy, and haemorrhage. Cardiac surgery is generally avoided during pregnancy, and is used when there are no other alternative options. Cardiopulmonary bypass (CPB) during pregnancy is associated with high foetal mortality. Maternal mortality in the setting of CPB however, is not dissimilar to a non-pregnant woman.

Case summary
We present the case of a 29-year-old woman with Ebstein’s anomaly who developed thrombosis of her mechanical tricuspid valve at 4 weeks’ gestation. This was suspected to be likely due to sub-therapeutic anticoagulation at the time of presentation. She underwent a tricuspid valve replacement during the first trimester of pregnancy after failing medical therapy, with overall favourable maternal and foetal outcomes.

Discussion
Valve thrombosis during pregnancy is a devastating complication. There is limited data surrounding the best management strategy of valve thrombosis in pregnancy. Cardiac surgery with CPB is reserved for cases refractory to appropriate medical therapy. Though maternal mortality is largely unaffected, foetal mortality with CPB remains high. The management of pregnant women undergoing CPB is unique and extremely challenging. It requires a meticulous, multidisciplinary approach to improve overall outcomes.
