THE LASER POWDER BED FUSION PROCESS DEVELOPMENT OF 17-4 PH STAINLESS STEELS WITH PULSED-WAVE LASERS

The main advantage of using Laser Powder Bed Fusion is its unique capability to produce highly complex geometries with intricate features. Besides other differences in powder coating and gas circulation among various LPBF machines, the type of laser (continuous or pulsed wave) is the most critical one. In addition to several process parameters to be optimized for a specific material, pulsed-wave lasers bring extra factors to consider. In this work, a pulsedwave laser was used to develop process parameters for 17-4 PH stainless steel while keeping volumetric energy density, laser power and velocity constant to understand the effect of pulse related parameters on the outputs. As the point distance (PD) between consecutive laser spots was increased, the exposure time was also raised to keep the scan speed constant. This enabled achieving PDs with one extreme end approaching CW-lasers while the other end aiming at keyhole effect.
Effects of non-genetic factors on production performance traits in Hardhenu crossbreed cattle

The data on 862 Hadhenu cattle sired by 63 pertaining to production performance traits up to five lactation were collected from history cum pedigree sheets maintained at Cattle Breeding Farm (CBF), Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar over a period of 20 years from 1997 to 2016. Analysis of variance done by restricted maximum likelihood method of Harvey (1990) using mixed linear model in which fixed effect of period, season of calving and random effect of parity was taken into consideration. The overall least-squares means for production performance traits viz. lactation milk yield (LMY), lactation milk yield-305 (LMY-305), lactation length (LL), peak yield (PY), average daily milk yield (AMY), milk yield per day of calving interval (MCI), milk yield per day of age at second calving (MSC) persistency, age at first calving (AFC), service period (S.P), calving interval (CI) and dry period (DP) were 3111.81± 110.17 kg, 2929.45±90.63 kg, 310.57±6.48 days, 14.65±0.48 kg/day, 9.92±0.24 kg/day, 7.80±0.23 kg/day, 1.93±0.07 kg/day, 208.94±5.86 days, 1235.22±19.53 days, 113.85±4.55 days, 401.65±5.53 days and 87.19±4.08 days, respectively. With regard to production performance traits, the effect of period of calving was statistically significant on all the traits except on AFC, SP, CI and DP. While, the effect of season of calving was non-significant on all the production performance traits except significant effect on AFC, SP, CI and DP. The effect of parity was found to be statistically significant (p<0.01), (p<0.05) on all the traits except on LL, PY, SP and CI. These differences in these traits might be attributed to variation in managemental practices and feeding regimes being followed at the farm. Moreover, the performance records of an animal should be corrected for classifiable non-genetic sources of variation, which is essential for obtaining precise estimates of genetic parameters.
Sharing Idiosyncratic Risk Even Though Prices

We design an infinite-horizon dynamic asset market experiment with perishable consumption and a long-lived asset where gains from trade originate from individuals experiencing idiosyncratic income shocks. Our study is based on the consumption-based general equilibrium theory (Lucas (1978)). The presence of traders having induced motive to smooth consumption is not sufficient to eliminate price bubbles. Despite the asset being consistently priced higher than the equilibrium price, traders are able to share idiosyncratic risk and attain higher welfare. The co-existence of traders with income shocks along with those having no induced motive to trade does not hinder in the We gratefully acknowledge the financial support from the General Research Fund sponsored by the Hong Kong RGC (CityU 11500019), and the Nanyang Technological University, Singapore (MOE AcRF Tier 1 M4012114.SS0).

Do Competition and Market Structure Matter for Sensitivity of Bank Profitability to Business Cycle?

The aim of this paper is to determine what is the effect of competition on cyclicality of bank profitability. To answer this question we apply robust fixed effects estimator to unbalanced panel of individual bank level data covering the period of 2004-2015 in over 100 countries. In our study we control for market power and market structure, as proxies for competitive environment and for net interest margin (NIM), return on assets (ROA) and return on equity (ROE) to proxy bank profitability. Our results show that decreased competition is related with an increase in procyclicality of net interest margin. This effect, however, does not hold in high-income countries. As for the ROA and ROE we find comparable results, but the effect is not always statistically significant. Market structure does affect profitability in a statistically signficant way, but seems to be important for procyclicality of ROA and ROE. We also find that the link between competition and procyclicality of profitability is non-linear and inversely U-shaped. Thus, both high and low competition intensity may reduce procyclicality of profitability.
Theoretical analysis of a hybrid AM-VSB/QAM SCM lightwave system with adjustable preclipping levels

A model for the analysis of the performance of a hybrid multichannel amplitude modulation vestigal sideband (AM-VSB)/quadrature amplitude modulation (QAM) subcarrier-multiplexed (SCM) lightwave transmission system with adjustable preclipping levels is presented. In the proposed model, two-stage adjustable clipping effect due to the preclipper and laser are considered. The analytical result shows that in this hybrid system the bit error rate (BER) is improved while the carrier-to nonlinear distortion (C/NLD) ratio is degraded as the value of the preclipping factor, is decreased, and vice versa. The validity of this model is verified by comparing the theoretical optimal value of /spl tau/ which is derived using our approach with the existed experimental result.
Colour associated emotional and behavioural responses: A study on the associations emerged via imagination

Perception of colour stimuli is found to trigger correspond­ing emotional and behavioural responses within human beings. Literature establishes that red is stimulating while blue is pacifying. There seems to be divided theories on how these associations are being generated. It is argued widely that colour associated emotional responses are learnt and subjective while another theory is that it is a general innate response. A third theory discusses about a combination of both learnt and innate responses. The present paper reviews literature on the above three sup­positions and enlightens on a study done seeking innate, general emotional reactions triggered by colour stimuli. A questionnaire survey was conducted using guided imagination technique with a group of volunteer under­graduate students (n=86). The participants were guided to imagine five emotional/behavioural states spontane­ously and recognize the corresponding colour/colours. The findings to a greater extent support the general emotional responses triggered by colour stimuli. Red and orange (79%) was dominating in their imaginations as appetizing and blue as least appetizing (60%). None (0%) imagined red as a calming colour and blue (2%) as a violent colour. The study also revealed certain learnt emotional responses. For instance, white (51%) was found to be calming, suspect to be a religiously and so­cially learnt emotion.

SEED AND OIL PRODUCTIVITY OF SUNFLOWER (Helianthus annuus L.) AS AFFECTED BY THE TIMING OF WEED REMOVAL

Sunflower, one of the most important oil crops, is generally considered to be very competitive against weeds. However, this is not valid for all hybrids, weeds and conditions, since in many cases there have been reported yield losses up to 70%. A field study was conducted in western Greece to evaluate growth, grain and oil productivity of sunflower under different weed management treatments (weed free, weed presence for 2, 4 and 8 weeks after sowing). Grain yield of the several treatments resulted to losses up to 64% compared with the weed free plots. Oil concentration was not affected by the presence of weeds, however oil yield was also significantly reduced in the plots with a late weed removal, probably due to the seed yield reduction. The findings of the present study reveal the significant reduction of seed and oil productivity in sunflower due to weed competition and highlight the need of an early weed management.
Implementing a multiskilled workforce

Recent studies show the construction industry in the USA is facing a long term labour shortage. Multiskilling has been suggested as a strategy to address this issue by utilizing existing workers more efficiently. Multiskilling decreases the number of workers hired for a project and can improve productivity. Additional benefits include higher income and increased employability of the workforce. To take full advantage of these benefits, the workforce strategy and the planning and scheduling processes of a construction project must be adapted to use multiskilling effectively and efficiently. The multiskilled workforce should be scheduled and organized to maximize the duration of employment for workers, reduce the overall labour requirements and cover the skills combinations required by the project. This research synthesizes and formalizes the methods that successful construction companies are currently applying to implement a multiskilled workforce. A methodology for implementing multiskilling is outlined as well.
Structural , functional and molecular pathogenesis of pelvic organ prolapse in patient and Loxl 1 deficient mice

Pelvic organ prolapse is a worldwide health problem to elderly women. Understanding its pathogenesis and an ideal animal model are crucial to developing promising treatments. The present study aimed to investigate new clinical significance and detailed mechanism of pelvic organ prolapse by comparing the structural, functional and molecular dysfunctions of pelvic organ prolapse in patient and Loxl1 deficient mice. Our results showed that human vagina tissues from prolapsed site showed disarranged collagen and elastic fibers compared with the non‐prolapse tissue. A gene ontology (GO) analysis of differentially expressed genes revealed molecular changes mainly related to inflammatory response and extracellular matrix (ECM) organization. While the mice lacking Loxl1 developed stable POP phenotype and disordered ECM structure in histology. Such Loxl1 knockout mice exhibited a significantly urinary dysfunction and decreased mechanical properties of the pelvic floor tissues, implying that POP in human condition might be induced by progressively decreased mechanics of pelvic tissues following ECM catabolism. Similarly, we not only identified significant up‐regulated ECM catabolism processes and down‐regulated ECM synthesis processes, but also characterized high level of inflammatory response in vagina tissue of the Loxl1 deficient mice. Thus, all these pathological changes in the POP mice model was consistent with those of the clinical elderly patients. These findings provide new insight into remodeling of POP by LOXL1 regulation and be of great importance to develop combination treatments of ECM metabolism and inflammation regulation strategy.
The influence of implicit social pressure on prosocial behavior of adolescents

Adolescents are easily influenced by their peers, resulting in a phenomenon known as social pressure, which can have both positive and negative effects on the teens. This study addresses the influence of implicit social pressure on prosocial behavior (e.g., voluntary acts that benefit someone else) in adolescents aged 12–19. Specifically, this experiment measured the influence of prosocial, neutral, and antisocial pressure on sharing. This study consisted of 2 parts, part 1 (N = 101) and part 2 (N = 16). In a game similar to a dictator game, participants divided money between themselves and four teammates with whom they did a school project. Participants received manipulated social pressure by showing an example of how the money can be divided. We hypothesized that participants would share more after receiving implicit prosocial pressure, and that girls would share more than boys. Our results indicate that there was no difference in the way participants divided the money in the prosocial, neutral, and antisocial condition. In addition, there was also no statistically significant difference between boys and girls. These findings may implicate that implicit social pressure has no influence on adolescents’ behavior. However, methodological and contextual factors like the COVID-19 pandemic need to be considered.
Offshore power generation with carbon capture and storage to decarbonise mainland electricity and offshore oil and gas installations: A techno-economic analysis

This study investigates the techno-economic potential of offshore power generation from natural gas with carbon capture and storage to reduce the climate impact of mainland electricity and the offshore oil and gas industry. This potential is assessed through techno-economic assessments over two relevant cases ("floating" and "shallow water" cases) including comparison with relevant reference concepts. In the base case evaluation, the offshore power plant concept toward decarbonising mainland electricity results in high costs (178 and 258 $/MWh respectively for the floating and shallow water cases) compared to a reference onshore power plant with carbon capture and storage (around 95 $/MWh). However, a stronger potential is identified for the concept toward decarbonising offshore oil and gas platforms as the concept results in costs more comparable with the reference electrification concept (137 compared to 133 $/MWh in the floating case and 207 compared to 166 $/MWh in the shallow water case). Although the base cases show a limited potential for the offshore concept, the results show that with technological improvements (advanced capture technology, reuse of infrastructure.) and more suited case characteristics (development based on associated gas.), the offshore concept offers a significant potential for cost-efficiently decarbonising the offshore oil and gas industry, while a more moderate potential is foreseen for the decarbonisation of mainland electricity.
Mismeasuring Risk: The Welfare Effects of Flood Risk Information∗

Rapidly improving data and models are giving homeowners more information about their disaster risk while also increasing insurance premiums for the highest risk homes. In this paper, I study the economic consequences of using better flood risk models to more accurately identify and price flood insurance for high-risk homes. I estimate my results with administrative flood insurance policy data and a novel survey measuring flood insurance demand, risk perceptions, and objective risk. To identify the effects of risk information, I use variation created by outdated elevation data and risk models that caused high-risk homes to be misclassified as low-risk. My findings show that flood risk classification provides valuable information not only for insurers, but also for homeowners. Misclassifying high-risk homes as low-risk causes owners to underestimate their current and future flood risk, invest less in risk-reducing adaptation, and buy less flood insurance despite substantially lower premiums. Embedding these estimates in a sufficient statistics model with dynamic risk and endogenous risk beliefs and adaptation, I find that identifying and pricing the estimated six million high-risk homes outside the floodplain would increase social welfare by $138 billion. ∗I am grateful to Olivia Mitchell, Ben Keys, Ben Lockwood, and Arthur van Benthem for their patient and persistent guidance and invaluable contributions to this paper. I am indebted to Lynn Conell-Price for her collaboration designing the flood insurance demand and risk perceptions survey.

Ecosystem and productive benefits of the strategic inclusion of annual legumes into an annual ryegrass pasture in a no-tillage integrated crop-livestock system

Annual winter pastures are strategic components in crop-livestock systems in Uruguay. The aim of this study was to evaluate the N legume fixation into an annual ryegrass pasture contrasted to the N fertilizer addition. The experimental design was a randomized complete block design with 2x2 factorial arrangement of the treatments, two pasture types: a) annual ryegrass (Lolium multiflorum L.) pasture, and b) of annual ryegrass with two annual legume species (Trifolium resupinatum L. and Trifolium vesiculosum L.); and two levels of N fertilizer: a) no N fertilizer, and b) 64 kg N ha -1 . They were grazed with Holstein steers. Setaria italica crop was planted in summer to evaluate the carry over effects of the treatments on its herbage mass production. Pasture accumulated herbage mass was significantly increased with N fertilizer (P ≤ 0.01), increment of 1277 ± 322.5 kg DM ha -1 . The legume species’ addition plus N fertilization led to a higher nitrogen nutrition index in the mixed pastures. Ryegrass herbage mass was positively influenced by N addition, but with that there was a 47% of weed herbage mass increase in the pure annual ryegrass pastures. The average daily gain of steers was positively influenced by legumes, with an average of 1.01 kg PV day -1 in mixtures. N fertilizer addition allowed a higher stocking rate and higher animal production in winter. A carryover effect of the treatments was not found on S. italica accumulated herbage mass. Legumes’ addition to annual ryegrass allowed a greater animal performance but did not provide any additional benefit to the following summer crop.
A COMPARATIVE AND EXPERIMENTAL STUDY ON THE EFFECT OF HEAT TREATMENT CYCLES FOR PBF Ti6Al4V

Powder bed fusion (PBF) presents the highest level of technological maturity and industrialization level for metallic materials among other Additive Manufacturing technologies. The advantages of high geometrical complexity, ability to produce internal cavities, reduced lead time and buy-to-fly ratio enables a wide range of application areas from aerospace to biomedical. Laser-PBF and Electron-PBF present different limitations and opportunities while they can both build from Ti6Al4V powder. The performance of the E-PBF and L-PBF parts highly depends on the resulting microstructures and differs significantly due to various mechanisms such as preheating temperatures and processing environment. Moreover, the obtained material properties generally necessitate heat treatments for reducing residual stresses, enhancing mechanical properties and changing the microstructure. This study aims to investigate the effect of the same heat treatment cycles on the E-PBF and L-PBF microstructure evolution and microhardness by a comparative experimental work with several combinations of exposure durations, temperatures and cooling rates.
A portable capacitance probe for detection of interface levels in multi-phase flows – A case study

This paper describes the design and construction of a portable probe for monitoring the dynamics of the multi-phase flows within horizontal oil-water separators and presents some preliminary results from the industrial tests of the prototype device. The detection of individual phases is based on the measurement of dielectric properties of the process media, by means of an array of capacitance sensors, which are distributed along the body of the probe. The measurements of electrical capacitance are performed using electronic circuitry, based on charge transfer principle, which was originally developed at UMIST for tomographic applications.
Systematic Literature Review of Language Learning Strategies for Reading Skills in English for Specific Purposes among Business Students

This article analyses English language learning strategies adopted by students in learning English for Specific Purposes (ESP). Despite a broad study in language learning, there is still a scarcity of empirical evidence to emphasise the importance of LLS and the impact on students’ performance for ESP specifically. This topic is significant in reflecting the strategies and their adaptability by targeted students. It involves a systematic review of literature and studies from Malaysia and other parts of the world between 2009 and 2021. It references published research studies, analyses books and strategies students use in learning English and especially for specific purposes and reading skills. Out of 50 previous studies, 20 were chosen for a thorough analysis ranging from research journals, reports, and books on definitions and growth and development of ESP, and strategies for learning ESP. The studies revealed that though the majority of ESP students in Malaysia have embraced self-directed English language learning strategies, there is still a gap in the English proficiency in the Malaysian education system. While acknowledging the limitation occasioned by a smaller sample size, the study recommended the adoption of language learning from an out-of-classroom perspective and understanding the significance of Business English to students.
