Assessment of nutritional status of children (12-36 months of age) in urban area of district Rohtak, Haryana: a cross-sectional study

Background: Children 1-3 years of age are most vulnerable to the vicious cycles of malnutrition, disease/infection and resultant disability all of which influence the present condition of a child at the microlevel and the future human resource development of the nation at the macrolevel.Methods: Urban field practice area attached to the department of community medicine, Pt. B. D Sharma PGIMS, Rohtak being served by 14 anganwadi centres out of which 8 anganwadi centres were selected randomly. From each selected anganwadi centre, 22 children of 1-3 years of age group were selected by simple random sampling, thus, a sample of 176 children were included in the study.Results: Overall prevalence of undernutrition in our study was found as follows: wasted 14.1%; underweight 20.0%; stunted 24.1%. Inverse relation between prevalence of undernutrition and educational status of mother was observed. Children who were >3 in birth order had high prevalence of wasting, stunting and underweight. Children with low birth weight were having higher percentages of wasting, stunting, and underweight. Children who took supplementary nutrition regularly from AWC were less likely to be undernourished.Conclusions: Every endeavor should be made to combat the outcomes of undernutrition through multipronged approach such as growth monitoring, nutritional supplementation etc., Also, present study findings reinforce the importance of proper infant and child feeding practices and appropriate maternal care in prevention of childhood undernutrition.
Potential Application of Flashing Yellow Arrow Permissive Indication in Separated Left-Turn Lanes

The consideration being given to the adoption of the flashing yellow arrow (FYA) permissive indication has led to a number of additional studies evaluating potential scenarios in which FYA may be effectively used. One potential scenario is in intersections with wide medians where the left-turn lane and the corresponding signals are separated from the adjacent through and right-turn lanes. Left-turn maneuvers at locations with wide medians typically operate with protected-only left-turn phasing and separate signal displays, as drivers cannot see the adjacent through movement signals; however, some transportation professionals have implemented a flashing red arrow (FRA) that requires drivers to first stop before accepting a gap in the opposing traffic stream. This research quantified driver comprehension of the FYA permissive indications compared with that of the FRA indication for use at locations with wide medians. The research used both driving simulator and static experiments with 264 drivers responding to 1,260 experimental scenarios. The results found that drivers understood the meaning of the FYA indication. Nevertheless, FYA was associated with fail–critical response errors in the driver's first exposure to the FYA indication. The large number of drivers who interpreted the FRA as a yield condition was consistent with that from previous evaluations and indicated an incorrect comprehension of the indication. At locations with wide medians where the use of protected-only left-turn phasing may not be desirable, the use of the FYA or FRA permissive indications should be used only after consideration of the safety and operational issues common to the initial implementation.
Novel oscillator incorporating a compact microstrip resonant cell

A novel transistor oscillator incorporating a compact microstrip resonant cell (CMRC) as its terminating resonance is proposed. Adjusting the dimensions of the cell, it is possible that the fundamental frequency can be positively fed back and the second harmonic negatively fed back at the input port of the oscillator. The fundamental output is enhanced with the second harmonic being suppressed. The output power of the proposed CMRC oscillator is 14.7 dBm at 2.5 GHz with 27.1 dB rejection of the second harmonic, outperforming the conventional microstrip termination with a 40% size reduction.
Sexing as a tool for reinsertion of Amazona aestiva parrots to nature: use of less invasive technique

The sexing birds is considered an important tool for behavioral studies and programs for the reintroduction of animals into the wild. Several techniques are used for this purpose, such as laparoscopy, magnetic resonance and molecular sexing. The first are considered more invasive and stressful for the animal, and the last is considered the most accurate. According to it, the aim of this study was to compare the effectiveness of using three sets of primers in the molecular sexing process of true parrots (Amazona aestiva). Blood samples from 10 animals were collected at a Wildlife Screening Center (CETAS) in Bahia, Brazil. The DNA was extracted and the molecular markers amplified by Polymerase Chain Reaction (PCR) using primer pairs P2/P8, 1237L/1272H and 2250F/2718R. The amplified material was visualized with electrophoresis performed at 2% agarose and 12.5% polyacrylamide gels. Among the primer sets used, the 2250F/2718R pair showed the best results for the sexing process, including visualization of the amplified products on an agarose gel. Agarose gel electrophoresis is considered to be faster and cheaper. The results revealed a sample composition of 5 males (0.5) and 5 females (0.5).
MBE growth, fabrication, and electrical characterisation of terahertz frequency quantum cascade lasers

The terahertz (THz) range in the electromagnetic radiation spectrum lies between the high-frequency edge of the microwave band and the long-wavelength edge of the far-infrared band. THz technology is important for both scientific and commercial applications so the production of coherent, high power sources operating at room temperature is of great interest. Quantum cascade lasers (QCLs) are unipolar emitters operating from THz to infrared range. Molecular beam epitaxy (MBE) is the main technique for the growth of THz QCLs, offering precise control of layer thickness and composition under ultra-high vacuum conditions. The output power, maximum operating temperature, threshold and dynamic range are essential parameters in THz QCL performances. Since high power in THz QCLs is a desirable performance in particular to areas such as imaging and remote sensing. The threshold and dynamic ranges are influenced by the injector doping levels determining the losses. Moreover, the interface roughness affects the electrical and optical properties of semiconductor devices, which can be improved by misorientation of (100) GaAs substrates. This thesis reviews the development of THz QCLs, investigates MBE growth, fabrication and electrical characterisation process, and the enhancement of THz QCL performances. Chapter 1 summarizes the development and application of THz technology, different THz sources, as well as the development of THz QCLs. Chapter 2 outlines the MBE system, and investigates the calibration methods, the growth process, and growth reproducibility. Chapter 3 explains the fabrication techniques, electrical characterisation of THz QCLs, and the factors that influence the device performance. Chapter 4 investigates the enhancement in THz QCL power performance; whilst Chapter 5 probes the injector doping effects and background impurity level influences on BTC and hybrid THz QCL performance. In Chapter 6, the effects and possible significance of misorientation on THz QCLs are discussed. Chapter 7 concludes the thesis and suggests future directions.
Educating Library and Information Science Professionals in Kuwaiti Higher Education

The paper presents the results of 54 analysed interviews conducted to present the views and explanations of Library and Information Science (LIS) students, teaching staff and employers on the implementation of Information and Communication Technologies (ICT) skills into the LIS curriculum in Kuwaiti Higher education (HE). Semi-structured interviews were used to collect the qualitative data. The findings indicated that there was a lack of common understanding of the term ICT. LIS students lacked ICT skills. The LIS curriculum is outdated and the department uses traditional methods to teach ICT courses. Moreover, factors were found that negatively affected the students’ ICT skills development. The current students’ ICT skills did not satisfy the job market needs. The teaching staff ICT skills were not updated; ICT skills were not incorporated into non-ICT courses; and in general, respondents disapproved of the department’s name change from LIS to Information Science (IS). In order to satisfy the LIS professionals in Kuwaiti HE, initial indications suggest that LIS graduates should posses at minimum all the research defined skills in addition to other skills needed by the job market. The curriculum should be updated; more practical training should be provided; the department of LIS needs to add new ICT courses; support new learning methods to teach these courses; adopt professional associations’ standards to enhance the curriculum; collaborate with employers to meet their needs; the teaching staff needs to update their ICT skills and incorporate ICT skills into all courses. This initial phase of the research suggested that to overcome the negative motivational factors: students need to be motivated by family, friends and teaching staff; instruction of ICT courses should be in English; the same educational opportunities should be offered to males and females; and provide the necessary resources and facilities. These findings were recognised by the teaching staff.
Dynamic Responses of the Aero-Engine Rotor System to Bird Strike on Fan Blades at Different Rotational Speeds

To study the effect of a bird striking engine fan on the rotor system, a low-pressure rotor system dynamic model based on a real aero-engine structure was established. Dynamic equations were derived considering the case of the bird strike force which transferred to the rotor system. The bird strike force was obtained from the bird strike process simulation in LS-DYNA, where a smoothed particle hydrodynamics (SPH) mallard model was constructed using a computed tomography (CT) scanner, and finite element method (FEM) was used to simulate the bird strike on an actual fan model. The dynamic equations were solved using the Newmark-β method. The effect of rotational speeds on the rotor system dynamics after bird strike was investigated and discussed. Results show that the maximum bird impact force can reach 104 kN at 3772 r/min. Impact time is only 0.06 s, but the bird strike on fan blades lead to a transient shock on the rotor system. Under the action of transient shocks, the rotor system displacement in the horizontal and vertical directions increase sharply, and the closer the mass point is to the fan, the more it is affected; the vibration amplitude at the fan will increase 15 times within 0.1 s of the bird strike and will gradually decrease with the effect of damping. The dynamics of the rotor system changes from a stable single periodic motion to a complex irregular quasi-periodic motion after a bird strike, and the strike force excites the first-order vibrational mode of the rotor system. This phenomenon occurs at all speeds when bird strikes occur. Bird strikes will cause resonance in the rotor system, which may cause damage to the engine. It was also seen that the bird strike force, and hence the effects on the rotor system, increases as the engine rotational speed increases; the peak force is larger and the number of peaks has increased. The impact force at 3772 r/min is 99.5 kN higher than at 836 r/min, and three additional peaks emerged. This effect is more reflected in the amplitude, and the overall vibration characteristics do not change. Combining the bird strike with the rotor dynamics calculation, the dynamic response of the aero-engine rotor system to bird strike is studied at different flight stages, which is of guiding significance for power evaluation of aero engines after bird strike.

Consonant Repertoire of a Prelinguistically Deaf Child with Late-Mapping Cochlear Implants

Objective: The present case study aims to report on the consonant repertoire during the pre-linguistic and first linguistic stage of a Greek-Cypriot speaking child bilaterally implanted with multichannel Cochlear Implants (CIs). Background: Children with Hearing Loss (HL) produce canonical babble later, and consonantal inventories of HL children are smaller. However, the consonant repertoire of CI Greek-speaking children has not been examined thus far and research on types of consonantal errors during phonological acquisition is scant. Clinical Case: A pre-linguistically deaf child (CY, 7;0 years old) received the first CI at 7 months of age, but the external part of the device was fitted at 2;7 years. An investigation of the child’s speech at 7;0 years was conducted through auditory analysis. The child’s canonical utterances were transcribed in IPA and his consonants were classified into subcategories, depending on articulation place, articulation manner and resonance. Regarding place, alveolar consonants were the main category produced. As regards manner, closed consonants was the first category to appear, while in terms of voicing, voiceless consonants were recorded more often than voiced ones. The analysis also showed that consonants /t/, /s/ and /p/ were dominant in the child’s speech and revealed several phonological processes. Conclusion: The present case holds special interest as the child’s phonological system is still between the pre-linguistic/first linguistic stages due to the delayed CI mapping. The results agree in part with several studies in the literature, while specific phonological error patterns observed, remain to be verified in other CI Greek-speaking children.
SOC(HE)-Italy: A Classification for Graduate Occupations

This paper presents an application to the Italian labour force of the British SOC(HE)2010 classification for graduate occupations, thereby creating a statistical tool for exploration of the Italian graduate labour market. In order to achieve this goal, the classification is replicated, using methodology that differs slightly to take account of differences in existing Italian data, to construct SOC(HE)-Italy. This classification allocates each of the official 800 Italian occupational categories to four groups distinguishing between ‘graduate’ and ‘non-graduate’ groups on the basis of their relative levels of knowledge and skills requirements. It is then validated using the Rilevazione Continua sulle Forze di Lavoro (RCFL ISTAT) data and the AlmaLaurea (AL) data and used to analyze changes in the Italian occupational structure that occurred before and after the financial crisis that took place in 2008. We also compare the Italian structural trends in the graduate labour market with similar trends in Britain. This analysis reveals that the decrease in the utilization of highly qualified labour in the Italian labour market started before the beginning of the ongoing recession, which contradicts the findings of analyses reported in earlier literature.
Prevalence of Food Allergy in Egyptian Patients complaining of food adverse events attending allergy clinic at Ain Shams University Hospitals

Food allergy is defined as an immune reaction to proteins in the food and can be immunoglobulin (Ig)E-mediated or non–IgE-mediated. IgE-mediated food allergy is a worldwide health problem that affects millions of persons and numerous aspects of a person’s life. Allergic reactions secondary to food ingestion are responsible for a variety of symptoms involving the skin, gastrointestinal tract, and respiratory tract. While all other non-allergic food reactions are categorized as “food intolerance”. to assess prevalence of Food allergy among Egyptian patients complaining of food adverse events attending Allergy clinic at Ain Shams University Hospital. This was a randomized cross sectional study involving 200 patients complaining of food adverse events attending Allergy clinic at Ain Shams University Hospitals between the first of February 2019 till the end of January 2020, 90 patents had confirmed food allergy The Total patients who were presented to the Allergy outpatient clinic at Ain Shams University hospital between the first of February 2019 and the end of January 2020 were 200 patients presented complaining of food adverse events with the percentage (9.5%). Among the 200 patients presented complaining of food adverse events, there were 90 patients who were confirmed food allergy. food allergy may be over estimated along patient with food adverse events.
Predictions of the axial tensile property of the unidirectional composite influenced by microfiber breakage defects

This paper primarily investigated the effect of fiber breakage defects on tensile properties of the unidirectional composite (UD) using the numerical simulation method. Different kinds of fiber breakage defects were firstly proved to exist in the UD according to the sub-micro computed tomography images at the microscale level. A strict random uniform distribution hypothesis was then proposed to introduce fiber breakage defects into the composite. Numerous microstructural models within random fiber breakage defects were created with the Monte Carlo method to analyze the fiber breakage defect effect on the UD. The results show that the tensile modulus of the UD was reduced by 17% when the fiber breakage defect volume fraction was only 1%, which indicates the effect of this kind of defect was very significant. The fiber volume fraction, defect volume fraction and property all have influences on the decrease of the UD caused by the fiber breakage defect. Finally, we derived a mathematical model to calculate the tensile modulus of the UD based on the numerical results. The proposed mathematical model has an application on the prediction of the axial modulus of the UD or the fiber tow containing large numbers of fiber breakage defects in the composites with complicated structure.
Dislocations Stabilized by Point Defects Increase Brittleness in PbTe

Dislocations and the residual strain they produce are instrumental for the high thermoelectric figure of merit, zT ≈ 2, in lead chalcogenides. However, these materials tend to be brittle, barring them from practical green energy and deep space applications. Nonetheless, the bulk of thermoelectrics research focuses on increasing zT without considering mechanical performance. Optimized thermoelectric materials always involve high point defect concentrations for doping and solid solution alloying. Brittle materials show limited plasticity (dislocation motion), yet clear links between crystallographic defects and embrittlement are hitherto unestablished in PbTe. This study identifies connections between dislocations, point defects, and the brittleness (correlated with Vickers hardness) in single crystal and polycrystalline PbTe with various n‐ and p‐type dopants. Speed of sound measurements show a lack of electronic bond stiffening in p‐type PbTe, contrary to the previous speculation. Instead, varied routes of point defect–dislocation interaction restrict dislocation motion and drive embrittlement: dopants with low doping efficiency cause high defect concentrations, interstitial n‐type dopants (Ag and Cu) create highly strained obstacles to dislocation motion, and highly mobile dopants can distribute inhomogeneously or segregate to dislocations. These results illustrate the consequences of excessive defect engineering and the necessity to consider both mechanical and thermoelectric performance when researching thermoelectric materials for practical applications.
Evaluation of Relative Density and Shear Strength of Sands from CPT and DMT

The paper summarises the experience gained by the writers in the interpretation of the cone penetration test (CPT) and flat dilatometer test (DMT) for the assessment of the geotechnical properties of sands. In the first part of the paper, the problem of determining the relative density (D R ) as function of the penetration test results and ambient stress (σ'), for silica sands, is dealt with. In the second part of the paper, the assessment of the peak angle of shearing resistance (φ' p ) is dealt with. The attention is given to the use of the Bolton's strength-dilatancy theory in order to estimate φ' p . Engineering correlations, based on Bolton's work, are proposed allowing estimation of φ' p as function of penetration resistance and σ', taking into account the compressibility and the curvilinear shear strength envelope.
Serviceability performance of fiber-reinforced lightweight aggregate concrete beams with CFRP bars

Six lightweight aggregate concrete (LWC) beams reinforced with carbon fiber–reinforced polymer (CFRP) bars were tested under a four-point bending load with different steel fiber contents, reinforcement ratios, and clear span lengths to investigate their flexural behavior and serviceability performance. The test results showed that using steel fiber–reinforced lightweight aggregate concrete (SFLWC) and increasing the reinforcement ratio enhanced the serviceability performance of the beams. The incorporation of 0.6% by volume of steel fibers reduced the midspan deflection by 22.70%–36.87% at the same load level in service stage. At service load, all the CFRP-reinforced beams exhibited conservative deflections when compared to the deflection limits recommended by ACI 440.1 R and GB 50608, and satisfied the crack width limit of 0.7 mm. Comparing the measured maximum crack widths with the corresponding predictions revealed that the bond-dependent coefficient value of 1.4 specified in ACI 440.1 R was reasonable yet conservative. Moreover, an energy-based method was adopted to quantify the influence of the fibers on the beam stiffness. On this basis, a rational deflection model for SFLWC beams reinforced with CFRP bars was suggested.
“What Was That Word? It’s Part of Ensuring Its Future Existence” Exploring Engagement Collectives at the European Commission’s Joint Research Centre

This paper provides an empirical analysis of an initiative to establish a Community of Practice on citizen engagement at the European Commission’s (EC) Joint Research Centre (JRC). This initiative is one of the more recent attempts to institutionally stabilize citizen engagement in policy-making processes within the EC; such attempts are visible, for instance, in the political agenda of Ursula von der Leyen, whose sixth priority is a “new push for European democracy. ” Drawing on science and technology studies literature, this paper directs attention to models of participation and democracy visible in particular engagement activities and to the overarching rationales for engagement. We explore the sociomaterial engagement collectives that emerge in the practices and accounts of actors involved in establishing this CoP and show how these engagement collectives at the supra-national research service JRC are co-constitutive with the wider institutional settings and cultural–political configurations of the EC.
