Authors: Rana K.P. , Kaphle K. , Gautam G.
Published: August 2019

The aim of present study was to assess the status of welfare of indigenous cattle, based on certain animal-linked parameters: body condition (BCS), body hygiene (cleanliness), lameness, skin injuries, general condition, and flight distance. The study was ruled in eight herds (10 cows /herd) in Terai and Mid-hill region of Nepal from March to June 2014. Altogether 80 cattle kept in semi-intensive system were assessed using several indicators determined through specific methods. Out of 80 cattle, 2 (2.5%) had BCS between 1.5-2, considered as very thin cows; 49 (61.25%) had BCS between 2.25-2.75, considered as thin cows; 29 (36.25%) had BCS 3-3.75 considered as normal cows and no cows found with BCS more than 3.75 score; 69 (86.25%) had dung particles at their lower legs, 60 (75%) had dung particles at their flank region and 11(13.75%) had dung particles at their udder region; 4 (5%) were moderately lame, 27 (33.75%) had hairless spot on their different body parts(hock, knee joints, neck), 15 (18.75%) had swelling joints (knee joints); 10 (12.5%) showed fear at the observer’s approach. The general condition was good of all the assessed cows. The obtained results indicate that more than half of the assessed cows are thin and dirty which has a negative impact on their health and welfare. The main factors that affect the indigenous cattle welfare in Nepal are insufficiency of feeding, poor housing system, poor sanitation and hygiene maintenance, lack of treatment of injured/diseased cattle and somewhat poor human animal relationship.

Published: August 2019

In the present work, three optically transparent tungsten niobate tellurite glasses with compositions of (90-x)TeO2-10Nb2O5-xWO3 (x = 0, 6, 12 mol%) were synthesized by conventional melt quenching technique. For all these three glass samples, the structural and the compositional dependence of different physical parameters such as density, molar volume and ionic packing density have been analyzed. It been observed that the amorphous nature of the samples has been confirm by X-ray diffraction analysis. The physical properties of the glasses were evaluated and the change in density ( ), molar volume ( ) and ionic packing density ( ) in these glasses indicates the effect of WO3 different content registered on the glasses structure. The highest refractive indexes value 2.171 at 632.8 nm was measured for 78TeO2â€“10Nb2O5â€“12WO3 glass. It is found that the addition of WO3 concentration to TeO2-Nb2O5 glass system increase the value of density, molar volume as well as ionic packing density. The refractive index value of the glass increase with tendency for small optical energy band gap.

Published: August 2019

Alors que se généralise progressivement l’ouverture des services de réanimation aux visites 24 heures sur 24, la présence des enfants semble encore controversée. Les unités de réanimation chirurgicale du CHU de Caen ont décidé de mettre fin à cette politique restrictive de visites. Cependant, accompagner un enfant face à la mort ou à la maladie ne s’improvise pas. La présence de ce « petit visiteur » est particulièrement stressante pour les familles et les soignants. Elle nécessite donc un encadrement spécifique, plus complexe que celui de l’adulte. En réponse à ce besoin, les équipes de réanimation du CHU de Caen ont développé divers supports (livret et pièce d’accueil, box de réanimation miniature) pour accompagner les enfants et soutenir les équipes soignantes dans cette démarche.
Paleoseismicity along Adyr faults (on example of Kokonadyr-Tegerek fault in South-Western Issyk-Kul lake region, Tien Shan)

Published: August 2019

We have studied paleoseismicity along a zone of the Kokonadyr-Tegerek adyr (foothill) fault in SW Issyk-Kul Lake region. It was shown that, although seismic movements continue along a zone of the tectonic contact of Paleozoic rocks of the Kokonadyr-Tegerek uplift and Quaternary deposits of the Alabash-Konurolyong depression, main number of appearance of seismogenic ruptures in the surface shift southward on hundreds of meters from the adyr fault mentioned above. This process leads to a formation of multiple fault scarps and compensation grabens in their back parts. According to data of radiocarbon dating along the Kokonadyr-Tegerek fault zone there were 4 strong Holocene earthquakes occurred during time intervals: 1771–1785 AD, 1440–1515 AD, and also possibly in 2310–745 BC and 640–5300 BC. Judging by parameters of the fault scarps their magnitudes were M ≥ 7, and seismic intensity I0≥ IX. Strong seismic activity along the Kokonadyr-Tegerek fault zone continues at least from Mid-Pleistocene. Evidences of this statement are uplifted and abandoned river valley of that time in the uplift with the same name as well as significant accumulation of the lacustrine sediments in northern part of the Alabash-Konurolyong depression. Large thickness of the sediments is tied with glaciers melting in the northern slope of the Terskey Ala-Too Range, and abandoned valleys testify on significant tectonic damming. Most proper model explaining formation of the adyrs (foothills) in the southern part of the Issyk-Kul Depression is a model of a gently dipping main fault flattening out northward, which is complicated by the underthrusts. All obtained data can be used at compilation of a new Map of Seismic Hazard of Kyrgyz Republic.

Published: August 2019

Background:

Type 2 diabetes (T2D) is associated with an increased risk of cognitive impairment and dementia with poorly understood underlying mechanisms.

Objective:

We examined the role of blood pressure (BP), aortic stiffness, and hemodynamics in this association.

Methods:

Cross-sectional sample of late middle-aged twins discordant for T2D from the Australian Twin Registry. Measurements included neuropsychological battery and brain MRI including arterial spin labelling (ASL) to measure cerebral perfusion. Mobil-o-Graph devices were used to non-invasively obtain 24-hour BP, aortic stiffness, and hemodynamic measures. Using mixed modelling, we studied associations of T2D with cognition, MRI measures, BP, aortic stiffness, and hemodynamics.

Results:

There were 23 twin pairs with mean age 63.7 (SD = 6.1) years. T2D (β=–0.45, p < 0.001) and age (β=–0.05, p = 0.022) were independently associated with poorer attention but not with memory or perceptual speed. T2D was associated with reduced nocturnal central systolic BP dipping (β=–3.79, p = 0.027), but not with BP, aortic stiffness, cerebral perfusion, or other hemodynamic measures. There was a statistically significant interaction between T2D and central systolic BP dipping in predicting attention scores (both p < 0.05 for the interaction term) whereby there was a positive association between BP dipping and attention scores in those with T2D, but not in those without T2D.

Conclusion:

We found an association between T2D and reduced nocturnal central systolic dipping, but not with any other measures of BP, stiffness or hemodynamic measures. Further study of the role of nocturnal central BP dipping in the association between T2D and cognitive impairment may help identify potential mechanisms.

Published: August 2019

Background:

Aberrant amyloid-β (Aβ) deposition in the brain occurs two decades prior to the manifestation of Alzheimer’s disease (AD) clinical symptoms and therefore brain Aβ load measured using PET serves as a gold standard biomarker for the early diagnosis of AD. However, the uneconomical nature of PET makes blood markers, that reflect brain Aβ deposition, attractive candidates for investigation as surrogate markers.

Objective:

Investigation of plasma Aβ as a surrogate marker for brain Aβ deposition in cognitively normal elderly individuals.

Methods:

Plasma Aβ40 and Aβ42 concentrations were measured using the ultrasensitive Single Molecule Array (Simoa) assay in 95 cognitively normal elderly individuals, who have all undergone PET to assess brain Aβ deposition. Based on the standard uptake value ratios (SUVR) obtained from PET imaging, using the tracer 18F-Florbetaben, plasma Aβ was compared between 32 participants assessed to have low brain Aβ load (Aβ–, SUVR <1.35) and 63 assessed to have high brain Aβ load (Aβ+, SUVR ≥1.35).

Results:

Plasma Aβ42/Aβ40 ratios were lower in the Aβ+ group compared to the Aβ–group. Plasma Aβ40 and Aβ42 levels were not significantly different between Aβ–and Aβ+ groups, although a trend of higher plasma Aβ40 was observed in the Aβ+ group. Additionally, plasma Aβ42/Aβ40 ratios along with the known AD risk factors, age and APOE ɛ4 status, resulted in Aβ+ participants being distinguished from Aβ–participants based on an area under the receiver operating characteristic curve shown to be 78%.

Conclusion:

Plasma Aβ ratios in this study are a potential biomarker for brain Aβ deposition and therefore, for preclinical AD. However, this method to measure plasma Aβ needs further development to increase the accuracy of this promising AD blood biomarker.
Genomic Instability in Kidney Cancer: Etiologies and Treatment Opportunities
Authors: Pilié Patrick G.
Published: August 2019

Genomic instability is a hallmark of cancer, allowing for cancer initiation, proliferation, and progression through the accumulation of driver mutations. This instability seen in cancer arises due to a variety of factors in the cancer cell itself as well as in the cell’s environment, including endogenous and exogenous stressors leading to DNA damage in the setting of deficiency in DNA damage response (DDR). While genomic instability is beneficial to cancer cell growth and survival, it also creates targetable vulnerabilities in the cell. Kidney cancer displays low to moderate genomic instability, yet does not have frequent mutations in canonical DDR genes and is not typically responsive to DNA damaging therapies. In this review, the etiology of genomic instability in kidney cancer, with a primary focus on clear cell renal cell carcinoma (ccRCC) histology, is discussed; and, pre-clinical data supporting the use of agents targeting DDR in ccRCC is summarized with associated progress towards clinical applications.
Energy efficient opportunistic edge computing for the Internet of Things
Authors: Leppänen Teemu , Riekki Jukka
Published: August 2019

Edge computing in Internet of Things enhances application execution by retrieving cloud resources to the close proximity of resource-constrained end devices at the edge and by enabling task offloading from these devices to the edge. In this paper, edge computing platforms are extended into the data producing end devices, including wireless sensor network nodes and smartphones, with mobile agents. Mobile agents operate, as a multi-agent system, on the opportunistic network of heterogeneous end devices. The benefits include autonomous, asynchronous and adaptive execution and relocation of application-specific computational tasks, while taking into account the local resource availability. In addition to the vertical edge connectivity, mobile agents enable horizontal sharing of information between these devices. Use cases are presented where mobile agents address challenges in current edge computing platforms. An edge application is evaluated where mobile agents as a multi-agent system process sensor data in a heterogeneous set of end devices, control the operation of the devices and share their tasks results in the system. The mobile agents operate atop a REST-compliant software agent framework that relies on embedded Web services for interoperability. A real-world evaluation and large-scale simulations show that energy consumption is reduced significantly, up to 60%, in the edge application execution.

Authors: Cheng Seong Khor , Gulabrai Lalchand
Published: August 2019

Malaysia’s electricity generation mix is mainly based on fossil fuels, particularly natural gas and coal with a smaller share of large hydroelectric and non-hydroelectric renewable energy resources. The present work aims to analyse and assess the ongoing search for alternatives to fossil fuel for electricity generation that the country has been pursuing both environmental preservation and national energy security considerations, thereby suggesting the way forward including potential options to be deliberated. This paper surveys alternative, both practical and theoretical that can be considered technically and economically attractive for Malaysia over the period to 2050. The overall national energy supply and demand situation are first analysed to develop projections that account for the role of renewable energy, particularly that of solar photovoltaic (PV). Next, the paper discusses the progress achieved, and the current status of the national solar PV industry presents the advantages or benefits offered and outlines the remaining challenges. In the same manner, electricity generation from the biogas produced from methane recovery in treating palm oil mill effluent (POME) is assessed. In the final analysis, the paper considers other potential low carbon power generation options to make up the Malaysian energy mix, which include small hydroelectricity, municipal solid waste decomposition in suitably-engineered landfills, nuclear energy using thorium-based technology, and renewable marine energy particularly ocean thermal energy conversion (OTEC), in tandem with savings expected from energy efficiency and conservation (EE&C) initiatives.

SYNTHESIS OF NANOSCALED MAGNETIC MATERIALS ON THE BASIS OF OXIDE SYSTEMS AND MANUFACTURING OF NON-RECIPROCAL COMPOSITE ELEMENTS BASED ON THEM
Authors: Fedorchuk Oleksandr , Solopan Sergii , Popov Maksym , Zavislyak Igor , Belous Anatolii
Published: August 2019

Nanoscaled particles of nickel-zinc ferrites solid solutions were synthesized by the method of precipitation from aqueous solutions, as initial reagents were used nitrates solutions, namely Fe(NO3)3, Ni(NO3)2 and Zn(NO3)3. Cylindrical composite resonant elements in a form of systems “high-Q non-magnetic dielectric – magnetic film” were manufactured using synthesized particles. As a non-magnetic dielectric was used barium tetratitanate BaTi4O9 with a doping of ZnO. For this the film-forming suspension consisted of synthesized ferrite particles and photopolymer was prepared. The suspension was applied on the end face of the dielectric resonator and polymerized by the UV radiation. Magnetic field of electromagnet was applied to the composite resonators during the magnetic film polymerization process (parallel or normal to the resonators axis).

Absorption spectra of composite resonators in the waveguide measuring cell under influence of an external magnetic field were obtained. Spectra confirm the opportunity to control the resonance frequency of the composite structure and energy absorption in it using the external permanent magnetic field. The tuning of composite resonators parameters was more efficient for the resonators with the film polymerized in the parallel to the resonator axis field. For the frequency shift and electromagnetic isolation were obtained the values of 71 MHz and 53 dB respectively but with a high “straight” energy losses in the area of ferromagnetic resonance. So, the measuring cell with the composite resonator located in it was simulated using an Ansys HFSS software. Respective absorption spectra were obtained. It is shown that it is possible to manufacture composite resonators with a needed for the practical applications characteristics level (reverse losses were 34 dB, straight losses were 0.8 dB) and a tuning ability for the development of superheterodyne transmitters, dynamic filters for microwave technics, microwave valves, etc.
