Systems of concentrate allocation for dairy cattle 2. A comparison of two patterns of allocation for autumn-calving cows offered two qualities of grass silage ad libitum

In a 25-week experiment beginning at week 3 post partum , grass silages of 10·5 (H) and 8·9 (L) MJ metabolizable energy per kg dry matter (DM) were offered ad libitum to two groups of 24 autumn-calving dairy cows. Within each silage-quality group, two patterns of concentrate allocation were compared, a flat-rate (F) and a variable rate (V). All four treatment groups, HF, HV, LF and LV, received on average 1575 kg fresh weight per cow of a concentrate containing 170 g crude protein per kg during the 25 weeks. The cows on treatment F were all individually given 9 kg concentrate per day throughout. Individuals on the V treatments received different levels of concentrate, based initially on their 14-day milk yield and then reduced by 1 kg/day at 10, 15 and 20 weeks. For treatments HF, HV, LF and LV respectively, mean adjusted daily milk yields were, 24·4, 24·1, 21·6 and 22·1 kg; intakes of silage DM, 9·1, 8·7, 7·6 and 7·6 kg/day, and live-weight gains, 0·39, 0·31, 0·28 and 0·22 kg/day. The effects of silage quality were significant in each case, but the effects of pattern of concentrate allocation were not. Cows given the H silage produced milk with significantly greater lactose and solids-not-fat concentrations. During the residual period (2 weeks indoors and 14 weeks grazing) no significant differences in milk yield were observed. The 305-day yields of 6215, 6096, 5786 and 5824 kg for treatments HF, HV, LF and LV respectively, reflected the differences obtained during the indoor feeding period.
The copy number of the gene in chromosome of strain detected by the real time quantitative PCR

To establish a real time quantitative PCR method for detecting gene copy numbers in chromosome DNA of bacteria. Methods Ct values of genes zot and thyA of Vibrio cholerae strains are detected, and the difference of Ct values between these two genes is identified. The copy number of gene zot of one strain is determined with the reference of Ct value difference of strain N16961. Results Copy numbers of zot gene among 11 of detected Vibrio cholerae El Tor strains were determined from 1 to 5 with thyA as the reference. It showed that the established method is as good as Southern blot in terms of detecting low copy numbers of genes, and is better for determining high copy numbers. Conclusion The quantitative PCR can be applied to accurately detect copy numbers of genes in chromosome DNA of bacteria strains.
Factor Structure, Reliability and Validity of the Institutional Culture Assessment Scale (ICAS)

Introduction: Work environment can affect the employees, fostering well-being versus emotional burden. The aim of this study was to develop the Institutional Culture Assessment Scale (ICAS), and evaluate its Factor Structure, Reliability and Validity in a Brazilian sample of medical students and physicians in different settings and phases of the medical career. Method: 2537 individuals were evaluated by an online questionnaire. The sample was split in half for independent testing of Exploratory Factor Analysis and Confirmatory Factor Analysis. We then used Confirmatory Factor Analysis (CFA) to test the best solutions in the second half of the sample. Then, considering a unidimensional model solution, an item response theory (IRT) analysis was conducted. Simple linear regression analysis was performed to investigate associations between ICAS factor scores and internal validators (burnout scores), using again the second half of the sample. Result: Parallel analysis revealed two factors. The first factor encompassed items involving the institution and supervisors. The second factor encompassed items involving peers. We decided to performed the next analysis with a unidimensional construct based solely on institution/supervisor items. A unidimensional model including the remaining seven items from the ICAS instrument revealed an excellent fit with the data. All items loaded significantly on the unidimensional latent trait with factor loadings ranging from 0.583 to 0.869. McDonalds Omega was 0.89, showing a high internal consistency. Conclusion: This study presents a valid and reliable scale to assess aspects of institutional culture connected to the relationships with superiors/supervisors and to the relation to the institutions themselves.
COVID-19 in Portugal: predictability ofhospitalization, ICU and respiratory-assistance needs

The current SARS-COV-2 epidemic is associated with nearly 1 million estimated deaths and responsible for multiple disturbances around the world, including the overload of health care systems. The timely prediction of the medical needs of infected individuals enables a better and quicker care provision for the necessary cases, supporting the management of available resources. This work ascertains the predictability of medical needs (as hospitalization, respiratory support, and admission to intensive care units) and the survivability of individuals testing SARS-CoV-2 positive considering a cohort with all infected individuals in Portugal as per June 30, 2020. Predictions are performed at the various stages of a patients cycle, namely: pre-hospitalization (testing time), pos-hospitalization, and pos-intensive care. A thorough optimization of state-of-the-art predictors is undertaken to assess the ability to anticipate medical needs and infection outcomes using demographic and comorbidity variables, as well as onset date of symptoms, test and hospitalization.
Duplicate news ﬁltering using sentence level heterogeneous graph

With the ﬂourishing development of the media of the network, dealing with the abusing news is becoming an essential requirement for portal news web-sites. However, previous research has only been attempting to improve the detecting eﬃciency or accuracy during ﬁnding near-duplicate news. Most of them rarely think about which news should be deleted or retained. Thus, we propose a heterogeneous graph-based news ﬁltering framework using novel sentence level graph model for a new generation of duplicate news ﬁltering, which is composed of two basic algorithms. First, extract and identify more duplicate news pairs by using sentence-level near-duplicate news detection algorithm; and second, calculate an accurate representative score by using the graph-ranking based on representative news selection algorithm. The proposed framework has been tested using real world dataset and the experimental result show that the proposed algorithms can improve the accuracy of descriptive news selection eﬀectively.
How are Online and Offline Political Activities Connected?

In general, political participation means all the action of citizens that has the aim or the effect of influencing government or politics. Studies argue that media consumption and political participation are correlated: offline and online political participation affect each other. Knowing the relationship between online and offline political activity can improve estimations of offline political events based on social media data. By comparing these empirical results, in this study we investigate whether social media usage reinforces or weakens the willingness to become involved in a demonstration or other offline political activity. Numerous studies have already attempted to measure this effect, with contradictory findings related to the direction and volume of the latter. We explore this connection by synthesizing recent empirical political science papers. For this purpose, we compare the results of the former using Bayesian updating – a tool for comparing studies regardless of their methodology or data collection method. This method of data analysis is also insensitive to the operationalization of either the dependent or the explanatory variables. Based on the aforementioned studies, our results prove that online political activity has a significant positive effect on offline political activity, in spite of the fact that some research has found an insignificant connection.
Intercropping of medicinal and aromatic crops in adult coconut garden under Brahmaputra valley region of Assam.

A field experiment conducted at Horticultural Research Station, Kahikuchi of Assam Agricultural University revealed the performance of medicinal and aromatic plants grown as intercrops in 32 year old Assam Green Tall coconut garden. There were three medicinal plants viz., sarpagandha (Rauvolfia serpentina), pipali (Piper longum) and vedailota (Paederia foetida) and two aromatic plants viz., citronella (Cymbopogon winterianus) and patchouli (Pogostemon cablin) in the experiment. The yield of all the medicinal and aromatic plants grown as intercrop in coconut garden were found to be reduced compared to their sole crop yields. The reduction in yield was less in patchouli (5.2%), followed by vedailota (7.0%), sarpagandha (8.9%), pipali (9.0%) and citronella (16.8%). The nut yield of coconut improved with intercropping with medicinal and aromatic crops. The piperine content in pipali, alkaloids in sarpagandha and essential oil content in patchouli were significantly reduced when grown as intercrops in coconut garden as compared to sole crop. However, the iridoid glycosides in vedailota and essential oil content in citronella were not significantly influenced by intercropping. Intercropping system of growing with patchouli under coconut recorded the highest net income (`178,089 ha) and B:C ratio (3.26) followed by sarpagandha (`157,484 ha and 3.09), pipali (`113,118 ha and 2.62), citronella (` 107,432 ha and 2.40) and vedailota (`100,382 ha and 2.36). Hence, intercropping of patchouli, sarpagandha and pipali with coconut can be recommended for Assam condition.
An introduction to forwarding Published as Chapter 4 in : Control of complex systems

This form is called feedforward form. It is obtained by adding recursively an integrator xi+1 fed forward with functions of all the previously introduced state components (x1, . . . , xi). The forwarding technique has been used in the design of controllers tested on real world applications. This is the case for instance for controlling down-range distance in guided atmospheric entry [11] or for swinging up 1D or 2D inverted pendulum [14]. For systems admitting a feedforward form, another technique, not presented here, has been developed in [15]. It is conceptualized around a small non linear gain Theorem. Also, we restrict our attention to global asymptotic stabilization. Other results are available, in particular for semi-global asymptotic stabilization (see [9]).
Etiology, Clinical Profile and Outcome of Acute Seizure in Children Aged between 1 month to 12 years Admitted in a Tertiary Care Hospital in Eastern India

Background: Acute onset seizure is one of the common causes of childhood hospitalization with significant mortality and morbidity. There is limited data regarding acute seizures episodes and its outcome from developing countries. Current study aims to find the common etiology of seizure and classify seizure types in various age groups. It was also aimed to find outcome in relation to diagnosis, abnormal imaging, EEG and requirement of monotherapy or polytherapy. Material and Method: This was a hospital based prospective study carried out in the department of Pediatrics, Calcutta National Medical College and Hospital from June 2016 to May 2017. Children aged 1 month to 12 years presented with acute onset seizure were enrolled. Variables collected were demographics, clinical presentation, laboratory tests, brain imaging, electroencephalography, diagnosis and therapy. The data was analysed using Statistical Package for the Social Sciences (SPSS) for Windows version 16.0 (SPSS Inc ; Chicago, IL, USA). Results: A total of 491 patients were admitted for acute onset seizure with 289(58.8%) males and 202(41%) females. Among these patient 280(57%) presented with fever and 55(10.9%) children presented with status epilepticus. Generalised onset tonic clonic was the most common seizure type, central nervous system infection was the most common etiology in all the age groups. Final outcome was made at the time of discharge as discharged without sequelae, dischaeged with sequelae and death. Patient with CNS infection had highest mortality. Conclusion: CNS infection and febrile seizure were common cause of seizure in fewer than 5 children. Group of children presenting with unprovoked seizure require long term follow up studies including neurophysiologic studies and neuroimaging for better understanding of childhood seizure disorder in developing countries.

Hurst exponents for Hasegawa-Wakatani turbulence

In magnetically confined plasma, it is of great interest to understand the statistics of the turbulent fluxes, which may be understood as stochastic. From a practical viewpoint, the turbulent fluxes may damage confinement by carrying strong transport; more theoretically, the turbulent fluxes fully characterize the dynamical evolution of the profiles. In particular, the tail of the distribution of fluxes contains information about intermittency: a fat tail is symptomatic of large transport events such as avalanches. Avalanches are known to carry a large fraction of the overall transport [1]. Besides the distribution itself, another useful measure of intermittency is a quantity known as the Hurst exponent H, named for hydrologist Harold Hurst [2]. The Hurst exponent, in a temporal analog of the structure functions used in fluid turbulence, gives the mean square deviation of a time series as a power of the time interval τ . Explicitly, for a time series X(t), H is defined by [3]
Influence of Silver Nitrate on Leaflet based Direct Regeneration in Arachis hypogaea L.

Peanut (Arachis hypogaea L.) family Leguminosae is one of the world’s most important oilseed crops. The effect of silver nitrate (AgNO3) on in vitro direct regeneration efficiency of leaflet explants was studied in two cvs ICG 7827 and 13942 of A. hypogaea. This study was conducted to explore the effect of silver nitrate (AgNO3) alone and also in combination with growth regulators, on multiple shoot formation and plantlet establishment from leaflet explants in peanut. The leaflet explants were cultured on shoot induction medium (SIM) containing MS salts with B5 vitamins fortified with AgNO3/BAP/KIN/TDZ alone, AgNO3 in combination with BAP/KIN/TDZ, and AgNO3+BAP+NAA/IAA. When AgNO3 added in combination with BAP+NAA/IAA, enhanced shoot buds induction was found in comparison to other combinations of PGRs used. Maximum average number of shoots (15.04±0.16) per regenerating explant was recorded with 86% of response at 2.0 mg/L AgNO3+10 mg/L BAP+1.0 mg/L NAA in cv ICG 7827 followed by 13.73±0.12 shoots/explant with 83% of response at 2.0 mg/L AgNO3+10 mg/L BAP +0.5 mg/L IAA in cv ICG13942. AgNO3 showed a positive and marked effect on direct enhanced level of multiple shoot induction from leaflet explants. The micro-shoots developed from leaflet explants were elongated on shoot elongation medium (SEM) fortified with 0.5 mg/L BAP. For in vitro rooting the elongated micro-shoots were transferred on to root induction medium (RIM) fortified with NAA/IBA/NAA+IBA and IBA+NAA. Maximum average number of roots (16.28±0.15) per shoot was observed with 90% of response at 1.0 mg/L NAA. The in vitro rooted plantlets were transferred into field. The survival percentage was found to be 90%.
Impacts of hydraulic fracturing development on macroinvertebrate biodiversity and gill morphology of net-spinning caddisfly (Hydropsychidae, Diplectrona) in northwestern Pennsylvania, USA

Hydraulic fracturing (fracking) poses significant threats to freshwater resources and stream ecosystems. Little research exists to quantify the ecological impact and in Pennsylvania alone over 10,000 wells have been permitted. This study aimed to determine if hydraulic fracturing is having any impacts on stream ecosystem health by measuring stream pH and temperature, macroinvertebrate index of biological integrity (IBI), and the gill morphology of individuals in the Hydropsychidae Diplectrona taxa. Six streams in northwestern Pennsylvania were selected as study sites (three with fracking occurring in their watershed and three without fracking). IBI scores were significantly higher at non-fracked sites and were also correlated with stream pH. Macroinvertebrate gill width did not vary between fracked and non-fracked sites but was correlated with percent hydric soils, suggesting that hydric soils may be a good long-term indicator of stream dissolved oxygen. While our results did not indicate differences in Hydropsychidae Diplectrona gill widths between fracked and non-fracked sites, we did observe that fracked sites had more acidic stream water and lower IBI scores. These results indicate the need for further study to assess the potential impacts of hydraulic fracturing on stream ecosystems.
Acoustic liner test of DGEN 380 turbofan engine

Acoustic liner is one of the most effective devices for aero-engine noise suppression, especially for fan noise suppression. Its fundamental characteristics can be obtained by impedance tube measurements or by impedance eduction with grazing flow duct facilities, however in the product development stages it is necessary to evaluate its performance on large scale models, such as rotating fan rigs or real aero-engines. Japan Aerospace Exploration Agency (JAXA) introduced a small turbofan engine called DGEN380 for engine noise studies and has carried out outdoor tests since 2016. In this study, to achieve the fan noise reduction, the acoustic liners are designed. Then curved acoustic liner panels are fabricated by 3D printer and installed in an intake duct upstream of the fan blades. The acoustic performance of the liners is evaluated by two measurements. First, in-duct acoustic mode propagation is measured by the microphone array uniformly distributed both azimuthally and axially inside the duct surface at the upstream of the liner. In the other, sound radiation pattern from the engine is obtained by 20-meter arc microphone array measurement. From the results of both measurements, the noise reduction at the designed frequency bands is confirmed.
A fast single image dehazing method based on statistical analysis

In this paper, we propose a new single-image dehazing method. The proposed method constructs color ellipsoids that are statistically fitted to haze pixel clusters in RGB space and then calculates the transmission values through color ellipsoid geometry. The transmission values generated by the proposed method maximize the contrast of dehazed pixels, while preventing over-saturated pixels. The values are also statistically robust because they are calculated from the averages of the haze pixel values. Furthermore, rather than apply a highly complex refinement process to reduce halo or unnatural artifacts, we embed a fuzzy segmentation process into the construction of the color ellipsoid so that the proposed method simultaneously executes the transmission calculation and the refinement process. The results of an experimental performance evaluation verify that compared to prevailing dehazing methods the proposed method performs effectively across a wide range of haze and noise levels without causing any visible artifacts. Moreover, the relatively low complexity of the proposed method will facilitate its real-time applications.
Telepediatric assistance in Iran: Specialist and subspecialty challenges

INTRODUCTION: Having justice for easy access to health services may probably be a standard feature and indisputable right of all health policies. The health policy of Iran enunciates this right. Unfortunately, as may happen in many countries, the execution of this policy depends on different factors. Among these parameters should be quoted as the suitable distribution of professionals, hospitals, and medical facilities. On the other hand, in Iran, there are many other problems linked to accessing areas with natural hindrances. OBJECTIVE: In this study, we analyzed the primary studies that report specialty and subspecialty challenges that had been faced by Iran to improve pediatric assistance. METHODS: Conduction of literature search in PubMed and CINAHL libraries was done, especially studies from 2010 to 2019. A Boolean operated ‘MeSH’ term was used for search. Newcastle–Ottawa Scale (NOS) scoring was adopted to assess the quality of each study. RESULTS: A total of 118 studies were displayed, and among them, 102 were excluded due to duplication and study relevance. Study selection was made based on its content were classified into two groups (1) shortage and unsuitable distribution of specialist and sub-specialist physicians in Iran, and (2) studies that explain the status of degradation in different areas of Iran. Outcomes demonstrated that Iran is generally suffering the shortage and unsuitable distribution of specialists and sub-specialists. This lack is particularly crucial in deprived and far-away areas from the cities. CONCLUSION: The present study analyzed in detail the current data regarding pediatric health services (specialist and subspecialty) and health-specific facilities distribution in the country. *Corresponding author.

Mineralogy, chemistry, and composition of organic compounds in the fresh carbonaceous chondrite Mukundpura: CM1 or CM2?

We present here several laboratory analyses performed on the freshly fallen Mukundpura CM chondrite. Results of infrared transmission spectroscopy, thermogravimetry analysis, and reflectance spectroscopy show that Mukundpura is mainly composed of phyllosilicates. The rare earth trace elements composition and ultrahigh‐resolution mass spectrometry of the soluble organic matter give results consistent with CM chondrites. Finally, Raman spectroscopy shows no signs of thermal alteration of the meteorite. All the results agree that Mukundpura has been strongly altered by water on its parent body. Comparison of the results obtained on the meteorite with those of other chondrites of known petrologic types leads to the conclusion that Mukundpura is similar to CM1 chondrites, which differ from its original classification as a CM2.
