Published: August 2018

AbstractBackgroundIn 2011, the IFCC Committee on Reference Intervals and Decision Limits (C-RIDL) initiated a worldwide multicenter study on references values facilitating the implementation of country-specific reference intervals (RIs). There has been no well-designed RI study in India. This study aims to derive RIs for 33 major biochemical analytes in carefully selected healthy Indians as defined in C-RIDL protocol.MethodsA total of 512 healthy Indians were recruited. Sera collected from overnight fasting blood samples were measured collectively for the analytes. Multiple regression analysis (MRA) and nested analysis of variance (ANOVA) were used to identify the potential sources of variation (SV) of test results. RI were derived by both parametric and non-parametric methods for comparison. The need for secondary exclusion by latent abnormal values exclusion (LAVE) method was examined.ResultsMRA results indicated that both age and BMI were apparent SV for many analytes in both sexes. ANOVA revealed that partition of RIs by gender and age was required for 17 analytes (TC, HDL-C, TG, hsCRP, ALB, AST, ALT, ALP, GGT, TBil, Urea, CRE, UA, Fe, TTR, CK and IgM) and 5 (Glu, ALB, TC, ALP and Urea), respectively. RIs by parametric method were generally narrower than by non-parametric method, reflecting distorted peripheral distributions of test results. The LAVE method had no appreciable effect on RIs possibly due to inconsistency among abnormal values of related analytes.ConclusionsThis study has for the first time provided comprehensive RIs information in healthy Indians. The final RIs adopted were those derived by parametric method without LAVE procedure.

Published: August 2018

Abstract
A capillary isotachophoresis (CITP) method performed in a column-coupling apparatus has been developed for the simultaneous determination of glutathione (GSH) and glutathione disulfide (GSSG) concentrations in blood samples. The determination of GSSG and GSH concentrations in biological samples is important because of their roles in oxidative stress. Different concentrations of a leading ion in the coupled columns (concentration cascade) and a large volume (37 µ ) of the injected sample facilitated a GSSG concentration of between 2 and 25 µmol/l. A reaction between iodoacetate and GSH under alkaline conditions was used to prepare the sample in order to avoid oxidation of GSH to GSSG. This step eliminated the main source of systematic errors with regard to the determination of the GSSG concentration. A linear relationship (R2=0.9969) between the zone length of S-(carboxymethyl)glutathione (the product of the reaction between GSH and iodoacetate) and the concentration of GSH (40-120 µmol/l) was obtained. The method was applied to the analysis of bovine blood samples that had been diluted by a factor of ten with satisfactory results
Study on a Motor Bearing Fault Diagnosis Method Using Improved EWT Based on Scale Space Threshold Method
Authors: Zhao Huimin , Zuo Shaoyan , Fang Jian , Deng Wu 
Published: August 2018

Abstract
Empirical Wavelet Transform (EWT) is a novel non-stationary signal analysis method that can effectively identify different mode components in signals. However, due to the lack of processing noise and unstable signals caused by the Fourier spectrum adaptive segmentation problem, an improved EWT (FCMEWT) method based on the scale space threshold method and fuzzy C-means is proposed to decompose the vibration signal into an empirical mode with physical meaning. The FCMEWT method firstly scales the spectrum of the original vibration signal, and then uses the fuzzy C-means method to classify the spectrum in order to obtain the spectrum division interval. The vibration signal is decomposed into a set of intrinsic mode functions (IMFs) components, which are performed Hilbert transform for extracting the frequency of each component through the power spectrum. Finally, Pearson correlation coefficient between each IMF component and the original signal is calculated to obtain the correlation coefficient threshold in order to determine the final IMF component. In order to verify the effectiveness of FCMEWT method, the vibration signal motor bearing is selected in this paper. The FCMEWT method is compared with the empirical mode decomposition (EMD) and ensemble empirical mode decomposition (EEMD) methods. The results show that the FCMEWT method can effectively solve the problem of Fourier spectrum segmentation in the EWT method, takes on better adaptive segmentation characteristics, and can effectively extract fault feature frequency of motor bearing. The fault diagnosis method can not only effectively extract motor bearing fault characteristics, but also has better diagnosis result than EMD and EEMD methods.

Published: August 2018

Abstract
This paper seeks to explain the structural effect on selected properties of freeze-dried gels with different compositions and aeration times. Herein, sugars and citric acid were added to gels with low-methoxyl pectin, mixtures of xanthan gum and locust bean gum, as well as xanthan gum and guar gum, in order to obtain a strawberry model. Strawberry pulp was also added to hydrocolloids to develop an innovative strawberry product. All samples were aerated for 3 and 7 min, and freeze-dried. Composition changes were found to modify the structure of the examined samples and properties. Freeze-dried gels with low-methoxyl pectin seemed to reflect the best approach towards obtaining an innovative strawberry product with a tailored structure, as they had the best water absorbent capacity, and the most attractive and delicate structure. Samples with a mixture of hydrocolloids were more compact. Aeration time did not significantly affect the examined parameters, while the addition of sugar and citric acid increased them. The strawberry pulp experiment confirmed the strawberry model (with low-methoxyl pectin gels, and sugar and citric acid), which had the finest structure and the best rehydration properties.

Abstract
Widely used in croplands, plastic mulch can significantly change land surface properties and energy partitioning. However, the magnitude of these modifications caused by plastic mulch (and its variations) on leaf area index remain largely unclear. Field experiments were, therefore, conducted to analyse the differences in energy partitioning between plastic mulch and non-plastic mulch conditions in cotton fields in arid Tarim Basin. Each component net radiation, surface soil heat flux, sensible heat and latent heat was either measured or estimated at different growth stages of the cotton crop. Results showed that the effects of plastic mulch on field energy partitioning was most evident when leaf area index was less than 1.0. During this period, net radiation decreased mainly due to the increase of surface reflectance. Surface soil heat flux and sensible heat were also increased due to the increase of surface temperature. Finally, latent heat decreased after plastic mulch application. As over 20% of net radiation was allocated to the soil surface under plastic mulch at the seedling stage, this suggests that surface soil heat flux should not be ignored for evaluating surface energy balance at the seedling stage under plastic mulch conditions.

Published: August 2018

Abstract
Nanoparticles serve as a new fertilization method utilised in agriculture, and their potential effect on medicinal crops has been mainly unexplored. In the present study, using ultrasonic irradiations, a novel nano-sized iron complex has been prepared from aminolevulinic acid and iron (III) nitrate under greenhouse conditions. The obtained Fe nano-sized energy dispersive X-ray spectroscopy complex has been characterized by two methods, i.e. Fourier-transform infrared spectroscopy and spectra. The morphology and size of the nano-complex were also determined using transmission electron micrographs and showed an acceptable size in the nano range (5-25 nm). In this work, purslane plants were supplied with Fe (III)-aminolevulinic acid asa new nano-sized complex and Fe-EDDHA. The mineral nutrient concentrations, total phenolic, ascorbic acid contents and antioxidant activity were the highest in the plants treated with the Fe-ALA nano-complex. Catechin was the predominant phenolic compound in all treated plants. The Fe nano-complex at the rate of 0.2% induced extra high-value phenolic compounds. The shoot Fe, Zn, N, Mg, Ca and K contents were also higher in the plants treated with the Fe nano-complex than in both the control group and the plants treated with Fe-EDDHA. In general, the nutritional and pharmaceutical quality of Portulaca oleracea L. improved when using the nano-sized Fe-ALA complex as a new iron source.

Abstract
For the purpose of this paper, sugar beet roots were loaded by creating the impact of aluminium bars falling from different heights. The time history of the force at the contact between the sugar beet root and the bar was measured. The response of the sugar beet root to the impact was evaluated in terms of surface displacement. This displacement was measured using a laser vibrometer. The displacement was studied in the time and frequency domain during the postharvest period, up to 71 days after crop collection. The measured parameters describing the sugar beet response were significantly sensitive to the storage duration, namely in the frequency domain. Correlations between the storage duration and the main parameters of both the force and surface displacement were identified (p < 0.05).

Abstract
The article presents a new diagnostic method of a motor starter based on the analysis of the starter’s power and the Hall effect. Using the Matlab Simulink program the wear and tear impact of the starter sleeves on power characteristics was simulated. For the analysis of the flux propagation and the distribution of magnetic induction for selected states of the wear and tear of the sleeve the QuickField program was used. Within the experimental tests, registration of the distribution of magnetic induction was conducted by the Hall sensor placed in the link slot. The model and the tests made it possible to develop diagnostic patterns within the OBD diagnostics.

Published: August 2018

Abstract
The article presents the description of the current systems of training military aircraft pilots. Particular attention has been paid to the trends of change aimed at reducing the cost of purchasing school aircraft and the burden on the entire training and aircraft operation system. Over the past 3 years, the annual Pilot Training Conference in London has dominated the issue of increasing the effectiveness of training pilots of combat aircraft and unmanned aerial vehicle operators. The results of training experiments were presented on this conference, which presented the abandonment of intermediate airplanes training process of military pilots. The results of different researches allowed to state, that on a well-designed school airplane, such as the Pilatus PC-21, one can train both basic and advanced trainings and then train pilots directly to the combat aircraft. Of course, all this training process should be intensively supported by the modern mission simulator of the 5th generation. This allows the thesis to be a future, innovative training system that significantly reduces the training costs of a combat aircraft pilot without affecting the quality of the training.

Published: August 2018

Abstract
The paper presents the basis of a new method for monitoring the technical condition of rotating blades during their operation. Utilizing the measurement of blade tip instantaneous speed under subsequent sensors, enables direct determination of the blade vibration frequency. The method utilizes a diagnostic model in the form of amplitude amplification W2
ij
and phase shift φ
ij of a diagnostic signal y(t) resulting from the operation of the blade and the signal from its environment, when the blade tip passes under a cascade of blade tip instantaneous speed sensors. The adopted diagnostic model, indirectly takes into account the current surrounding of a blade without the need to measure it [12, 14]. Evaluation of the blade technical condition in real time and static analysis shall be performed on the basis of the vibration process parameter analysis. The suggested method may play an important role in the diagnostics of rotor machine blades during their operation.

Published: August 2018

AbstractBackgroundIt has been demonstrated that vitamin B12 determinations fail, especially in patients with pernicious anemia with high titers of intrinsic factor antibody. Consistent with this finding, we observed a case of falsely normal holotranscobalamin (HoloTC) results in a patient with pernicious anemia and severe vitamin B12 deficiency. We aimed to investigate whether such a situation can also be seen in other individuals.MethodsWithin the frameworks of the SENIORLAB study and routine samples from a mixed patient population referred to a laboratory for investigation of B12 status, we searched for study participants displaying a normal HoloTC level (≥50 pmol/L) together with a decreased total vitamin B12 level (<125 pmol/L). Thereafter, we determined whether samples with discrepant biochemical markers (i.e. low vitamin B12, normal HoloTC) also had increased functional markers of vitamin B12 deficiency (methyl malonic acid [MMA], homocysteine [Hcy]) and/or a low value of Fedosov’s combined indicator of vitamin B12 status (<−0.5).ResultsThe prevalence of a normal HoloTC level and low total vitamin B12 level among the group of healthy seniors (n=1451) was 0.21% (95% confidence interval [CI], CI, 0.08–0.6%). Among the 106,635 routine samples with concurrent HoloTC and total vitamin B12 determination, 176 (i.e. 0.17%, 95% CI, 0.14–0.19%) had discrepant biochemical markers. Among them, 24 who were identified as having discrepant biochemical markers and a diagnosis of vitamin B12 deficiency could be confirmed with functional markers.ConclusionsInitial and isolated screening for vitamin B12 deficiency using a HoloTC cut-off of ≥50 pmol/L in a small subset of patients may reveal false-negative (normal) results, meaning that patients with vitamin B12 deficiency may remain undetected.

Published: August 2018

Abstract
Salt stress is a major abiotic stress that limits agricultural productivity in many regions of the world. To understand the molecular basis of the salt stress response, two wheat (Triticum durum Desf.) cultivars, Karim and Azizi, which are of agronomic significance in Tunisia, were grown under non-saline and saline conditions (100 mM). Leaves and roots of control and salt-stressed plants were harvested after 11 days of salt treatment.
Karim cultivar may behave as a typical Na+ include, which compartmentalizes Na+ within the leaf cell vacuoles where it could be used as an osmoticum to lower the osmotic potential necessary for the maintenance of the plant hydric status. While, accumulation of K+ was greater in Karim cultivar compared to Azizi, in both organs, presenting an important manifestation of salinity tolerance. Significant changes in metabolism of antioxidative system were observed, with an increase in protein tyrosine nitration, which indicates that salinity stress induces a nitro-oxidative stress.

Abstract
Nanotechnology is an emerging field of science widely exploited in agriculture in recent years. In this investigation, application of nanotechnology in agriculture via application of some nano-particles (nano-iron and nano-silicon) have been investigated in seed priming of dragonhead. Seeds were subjected to pre-hydration treatments by factor nano-silicon dioxide as; (S1) 0 mM or distilled water, (S2) 1 mM concentration and (S3) 2 mM concentration and and factor nano-iron oxide as; (F1) 0 Mm or distilled water, (F2) 1 mM concentration and (F3) 2 mM concentration. Germination percent, root fresh weight, shoot fresh weight, root length, shoot length, dry weight of the seed residue, root dry weight and shoot dry weight were measured. Analysis of variance showed significant variation for the main effect of nano-silicon dioxide as well as nano-iron dioxide in root length and dry weight of the seed residue. The interaction effect of nano-silicon × nano-iron priming treatments were significant in all of the measured traits except germination percentage and root fresh weight. The highest germination percentage was recorded in S2-F3, S3-F1 and S3-F3 while the root fresh weight was high in S2-F3 and treatments S1-F1 following to S2-F3 and S3-F2 produced the highest shoot fresh weight. Also, S2-F3 has the highest root length (16.1 cm) and the highest shoot length (18.4 cm). The best treatment combination suitable for obtaining of high values of germination characteristics of dragon-head was identified as S2-F3 (1 mM nano-silicon dioxide plus 2 mM nano-iron dioxide).
Analysis of anticancer efficiency of combined fractionated radiotherapy and antiangiogenic therapy via mathematical modelling
Authors: Kuznetsov Maxim B. , Gubernov Vladimir V. , Kolobov Andrey V. 
Published: August 2018

Abstract
One of the relatively new modalities in treatment of cancer is antiangiogenic therapy (AAT), which stops the formation of new blood vessels, thus leading to nutrient deprivation of a tumor. It has been discovered that it can cause transient alleviation of intratumoral hypoxia, which has induced interest in investigation of its combination with radiotherapy (RT), since presence of oxygen stimulates efficiency of the latter. Preclinical and clinical studies have shown ambiguous results concerning such combined treatment, indicating a need for theoretical investigation. For that purpose, we have developed a spatially-distributed mathematical model of tumor growth and combined RT with AAT. Model simulations in a physiologically justified range of parameters suggest that outcome of addition of AAT to RT should depend on the tumor radiosensitivity: under its low values, when RT de facto serves as a palliative therapy, inclusion of AAT may prolong patient’s survival; however, under high tumor radiosensitivity, AAT may compromise curative effect of RT.
