Authors: Morshedlou Amid , Dehghani Hesam , Hoseinie Hadi
Published: April 2020

Machine failures have destructive effects on continuity of operation and lead to production losses in long-wall mines, making proper maintenance scheduling essential. This paper models the reliability of the whole production chain in an Iranian long-wall mine including the drum shearer, Armored Face Conveyor (AFC), hydraulic powered supports, Beam Stage Loader (BSL), and main conveyer belt. Analyzing the computational results and failure frequencies, we rank the critical components and develop a reliability-based preventive maintenance schedule for all equipment. In respect to the data classification, conveyor belt with failure abundance of 41.5 percent is the most critical, while powered supports with the failure abundance of 1.2 percent shows the best performance. Approximately, the reliability of the production process after four hours reaches nearly to zero. Implementing the schedule, computational results suggest an increase of approximately 67.7 percent in the average production per shift.
Data Correction Method of The Persistent Scatterer Interferometric Synthetic Aperture Radar Technique in Landslide Surface Monitoring
Authors: Mowen Xie  , Fuxia Lv  , Liwei Wang
Published: April 2020

Landslides generally cause more damage than first predicted. Currently, many methods are available for monitoring landslides occurrence. Conventional methods are mainly based on single-point monitoring, which omits the aspect of variation in large-scale landslides. Due to the development of radar satellites, the differential interferometric synthetic aperture radar technique has been widely used for landslide monitoring. In this study, an experimental region in the Wudongde Hydropower Station reservoir area was studied using archived spaceborne synthetic aperture radar (SAR) data collected over many years. As the permanent scatterer interferometric SAR (PS-InSAR) technique is an advanced technology, it could be suitably used to overcome the time discontinuity in long time series. However, the accuracy of date processing obtained using the PS-InSAR technique is lower than that obtained using the single-point monitoring method. The monitoring results of the PS-InSAR technique only demonstrate the moving trend of landslides and do not present the actual displacement. The Advanced Land Observation Satellite and a high-precision total station were used for long-term landslide monitoring of the Jinpingzi landslide at the Wudongde Hydropower Station reservoir area. Based on a relationship analysis between the data obtained using the PS-InSAR technique and the total station, a revised method was proposed to reduce the errors in the PS-InSAR monitoring results. The method can not only enhance the monitoring precision of the PS-InSAR technology but also achieve long-term monitoring of landslide displacement from a bird’s-eye view.
Sequencing of ore columns for planning of large underground mines
Authors: Glass Hylke , Van Hout Gert
Published: April 2020

Block caving is an underground mining technique which extracts ore from the base, rather than from the top, of typically massive deposits. Mining infrastructure is developed below the deposit before extraction commences. A network of tunnels provides access to a collection of drawpoints from which ore is hauled. With large deposits, not all drawpoints are developed simultaneously and the opening of drawpoints is sequenced to facilitate orderly extraction of ore columns above drawpoints. Sequencing fixes the initiation point for the entire block cave, or a part of it, as well as identifying the direction of cave advancement. The drawpoint opening sequence exerts influence on the block cave mine economics. This paper discusses the optimisation of sequencing based on the net present value associated with extraction over the life-of-mine. It is shown that the maximum attainable net present value is obtained by a sequence in which ore columns are ranked in descending order of value. If significant variation of grade is present inside columns, an iterative procedure is given which corrects the sequence which yields the maximum net present value. The sequence with maximum net present value may not be practical or attractive from a caving perspective. Systematic design of sequences which permit orderly development of a block cave is discussed. To provide context, the net present value obtained from these feasible sequences is compared with the maximum attainable net present value. It is shown that the best feasible sequences are preferentially initiated in zones with columns of high-grade ore.

Chemical stabilization of soil is an effective improvement technique because it reduces the ability of ‎the soil ‎to swell. We added different proportions of magnesium chloride to an expansive clay and ‎performed ‎swelling, geotechnical characterization, and mechanical strength tests. The results show ‎that the swelling ‎potential and swelling pressure of the expansive soil were significantly decreased ‎by the addition of ‎magnesium chloride (MgCl2). This treatment also improved the physical and ‎mechanical characteristics and ‎microstructure of the soil. The soil’s plastic limit, shrinkage limit, ‎cohesion, and internal friction angle all ‎increased linearly with the addition of the MgCl2 stabilizer. ‎However, we observed that the liquid limit of the ‎soil decreased as the level of magnesium chloride ‎was increased.‎
Criteria determining school choice among the ethnic minority high school students
Authors: Tódor Imre
Published: April 2020

In our paper we sought for the answer to the question: based on which motives do students from various types of high schools (in our case, denominational or non- denominational school) make their choice of educational institution? The target group of our research consists of the 9th and 11th grade students of Harghita County’s denominational (Roman Catholic, Reformed, Unitarian) schools and the non-denominational ones added to them. All in all, eight high schools got into our sample. We conducted a survey by questionnaire, the sample including 1,064 people. We analyzed the decision criteria formed based on motives behind the decision (primary and secondary effects) on the one hand, and followed the decision making process on the other. The non-denominational sector is often chosen by the elite- and institution-oriented student group, who has great expectations of the institution, e.g. - top of the line standards of education, outstanding achievement indicators, prestige of the institution, local reputation. According to the clusters created from the motives, the value- and community-oriented student group, as well as the one following the orientation of the peer group, can be found in significantly higher proportion in denominational schools.

Since the political decision of the establishment of the dollar in 2000, the benefits that came alongside could change based on the evolution of money supply. Public debt has become the main element that has been supporting its functionality. If public debt is not replaced by a massive income of dollars to the economy, Ecuador could experience a regression in many of the economic and social variables. At the same time, from 2007 to 2017, Ecuador lived a period in which a new understanding of society was built making use of an adaptive leftist speech that would see reality through the existence of the victim, the messiah and the victimizer.

Control of spatial effects due to neighboring palms in coconut (Cocos nucifera) experiments
Authors: T. S. G. Peiris
Published: April 2020

The RCBD is the most robust design for field experimentations in coconut.  In this study the effect of neighboring palms to control local variation in field experiments of coconut was evaluated using two long-term coconut trials. Four types of spatial models are suggested to consider the spatial effect due to neighboring palms and the use of such models is illustrated using two long-term field experiments.  When data were analyzed separately by years or using repeated measures analysis, significant percentage reduction of CV was observed in all four spatial models relative to the RCBD model without covariates as well as pre-treat data as covariate irrespective of the experiment. Inclusion of the mean of two neighbouring palms in N-S or E-W direction as a covariate was clearly superior to the RCBD without covariate as well as pre-data as covariate when data were analyzed separately by years.   Inclusion of the mean of four neighbouring palms in N-S and E-W direction as a covariate was superior to repeated measures analysis in reducing local variation, irrespective of experiments. It is recommended to include effect due to neighbouring palms when analyzing field experiments in coconut. The methodology can be applied to other tree crop experiments as well.
Eco-friendly Traps to Control Sexapa sp.
Authors: Meldy L.A. Hosang
Published: April 2020

The indigenous insect, Sexava  sp. causes  serious damage to coconut palms/plantations  in some provinces of Indonesia. The objective of this study is to develop and evaluate the performance of three types of eco-friendly Balitka MLA-traps, standing alone and in combination with insect glue (fly glue and tangle foot). 

Balitka MLA trap was designed to capture the Sexava spp. especially during the night when they move from one place to another through the coconut trunk. The traps made from black cloth, insect glue, metal wire, and yarn were fixed on the coconut trunks at 1 – 1.5 M height. Three different types of traps namely Balitka MLA Trap A, B, and C were developed and evaluated. The study found that trap type C captured nymphs and adult of 1 – 7 nymphs/palm/day or 30-210 nymphs/palm/month. The trap also enabled natural enemies such as spiders and lizards to catch the snared pests easily. A total of 106 to 131 nymphs were caught by tangle foot and insect glue respectively after 3 months of fixing the traps in the field. These traps could potentially be used together with a biological control method to replace the use of insecticides in Sexava-infested areas.

This study was conducted in Talaud District, North Sulawesi Province, Indonesia from  2006 to 2007. Based on the study results, and considering the simplicity and eco-friendliness of the trap type C, it is recommended that it be used in coconut plantations to bring down the population of this insect pest, Sexava sp. and thereby control its damage to coconut palms.
Bio-softening of Coir Yarn for Ecofriendly Wet Processing
Authors: Anita Das Ravindranath
Published: April 2020

Conventional chemical bleaching of coir generates a considerable amount of effluent which is discharged into the local water bodies thereby affecting the water quality there. The possibility of bio-bleaching and bio-softening of coir yarn in order to reduce the requirement of softening and bleaching chemicals in wet processing of coir was studied. Treatment of coir yarn for 72 hrs using Trametes versicolor (NCIM 993) and Coirret, a bacterial consortium was carried out. The bio-treatment could impart an appreciable degree of softness to the yarn which was confirmed by the Flexural Rigidity Test. An improvement in softness of the yarn to the extent of 38% using bacterial treatment and 46% using fungal treatment was achieved. A noticeable change was observed in surface morphology of the fibre through SEM analysis. The lignin content of the fungal treated yarn was also reduced to some extent. An increase of 10% in Brightness Index of the fungi treated yarn was observed and a reduction in the requirement of bleaching chemicals could also be achieved. The physico-chemical parameters of the residual bleach liquor were also studied and a considerable decrease in BOD, COD and phenol content was observed.

Published: April 2020

Low temperature grafting of methyl methacrylate (MMA) on to coir fibre was carried out in aqueous medium using Potassium per sulphate (PPS) as an initiator under the catalytic influence of Ferrous ammonium sulphate (FAS). Optimization of various parameters of grafting viz. monomer, initiator and catalyst concentration, time and temperature was carried out to obtain the maximum tensile properties. Evidence of grafting was characterized from Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Thermal analysis (TGA). The maximum breaking stress (BS) of control and grafted coir fibre were 213.08 and 365.00 N/mm2 respectively. Hence the percentage of improvement of grafted coir fibre was found to be 71.30%. Increase in tensile properties with maximum BS observed under monomer (25%), initiator (0.75%) and catalyst (0.75%) concentration, time (150min) and temperature (500C) respectively.  The t-test and Analysis of variance (ANOVA) were studied for statistical significance and the P values obtained were less than 0.05 which revealed that the value was highly significant for the improvement of mechanical strength on coir fibre by graft Co- polymerization.
Comparative Evaluation of Sri Lanka Tall and Dwarf x Tall Coconut Hybrids for Tolerance to Weligama Coconut Leaf Wilt Disease in Sri Lanka
Authors: S.A.C.N. Perera
Published: April 2020

Weligama Coconut Leaf Wilt Disease (WCLWD) is a phytoplasma disease found in Southern Sri Lanka. It is an incurable, debilitating disease resulting in yield loss and ultimate death of the palm and over 250,000 palms have been identified to be infected. Breeding coconuts for resistance is a viable option in managing incurable diseases and for this WCLWD resistant germplasm is needed. Accordingly, the objective of the current research was to investigate the comparable levels of WCLWD resistance of Sri Lanka tall and CRIC65 coconut cultivars which are favoured in Sri Lanka.

         Eight coconut estates which were planted with Sri Lanka tall (SLT) and CRIC65 hybrids as a mixed plantation or in close proximity were observed. Out of them an extent of about 04 acres of one estate was selected for detailed analysis using the disease severity index developed based on the WCLWD symptoms; flaccidity, leaf yellowing and marginal necrosis of leaflets.

         General observations indicated the presence of WCLWD in both SLT and the hybrid CRIC65. Marginal necrosis was at a minimal level in both the cultivars, while the other symptoms; flaccidity and yellowing scored higher values at all levels in the spiral in SLT than in hybrid CRIC65. Moreover, the hybrid coconut CRIC65 displayed lower percentage of disease incidence and significant reduction in the levels of the main symptom flaccidity.  As a result, the hybrid palms recorded significantly low disease index value than SLT. Moreover, disease incidence was observed to be low in properly managed estates irrespective of the cultivar. With the findings of the current study, coconut varieties SLGD and selected SLT which remain healthy under the same disease pressure can be recommended as parents in a breeding programme aiming at resistance/tolerance to WCLWD.

Authors: Hengky Novarianto
Published: April 2020

Aceh province is one of major coconut producing areas in Indonesia. In 2013 coconut areas in Aceh province was 107,654 ha in which total production of copra was equivalent to 63,743 tons.  The entire coconut area in Aceh belong to smallholders. The coconut production in this area began to decrease in 2005 by an average of 9 percent per year, which was mainly caused by the tsunami.  This had resulted in damage to many crops. Efforts to increase production and productivity of coconut plantation in Aceh needed rejuvenation of the old or unproductive coconut palms with the use of seeds of improved quality.  Based on the results of the research conducted during 2014-2016, it is known that the origin of the Lampanah tall is passed from generation to generation and is a native of coconut in Aceh Besar Regent, Aceh Province. The morphology of Lampanah tall coconut comprising of the crown of leaves, stems, flowers and fruits in general is quite uniform. Of the data on the 23 quantitative characters, all have a value of coefficient of variance below 20%, except the character of 11 leaf scars obtained 23.29%. In the case of polar girth, Lampanah tall coconut is generally greater than the equatorial girth, fruit shape classified as round, egg-shaped and elliptic. The seednut of Lampanah tall generally round shape. The Lampanah tall coconut has the number of bunches at 13.35/palm and the number of fruit at 9.25 fruits/bunch or an average of 138 fruits/palm/ year. Fresh coconut meat weight is 449 g/nut or approximately 224 g copra/nut and the potential for copra production was 30.97 kg/palm/year or 3.80 tons of copra/ha/year. The fat content of Lampanah tall coconut was 66.40%, the water content of copra approximately 3.42% and protein at approximately 6.81%. Total saturated fatty acids was at 94.27%, medium chain saturated fatty acids at 67.21% and lauric acid content at 46.50%. The seed source of Lampanah tall coconut has been a selection of as much as 72 Selected Mother Palms (MAS) from a total of 407 palms of the High Yielding Block. The selected population is characterised with traits like copra yield more than 2.0 ton/ha/year, free from attack pests and diseases, number of bunch more than 12 per year, total nuts more than 7/bunch and weight of meat more than 400 g/nut. The MAS of Lampanah tall whole coconut has been marked using GPS. The Aceh government will build a minimum of 5 ha Coconut tall Seed Gardens on government land, as the development of source of Lampanah tall seednuts. Based on the above results, it can be concluded that the Lampanah tall coconut with plenty of nuts, at an average of 138 nuts per palm could be released as one of the national high yielding coconut.
The Most Frequent Agronomic Practices Used by the Coconut Farmers in the “Coconut Triangle” of Sri Lanka
Authors: Lalith Perera
Published: April 2020

The study was carried out to identify the most frequently practiced cultural practices by coconut growers in the main coconut growing area termed as “Coconut Triangle”, among a set of technical practices recommended by the Coconut Research Institute of Sri Lanka (CRISL). The objective was also to analyse the impact of these practices to the yield and to analyse the effects of the information sources to the growers to enhance the farmers skills. The study was carried out between June 2018 and August 2018. For the data collection, a questionnaire developed by CRISL was used and 62 growers were randomly selected. All the answers were gathered in a table file. Then, the data were analysed using tabular analysis and the software SPSS. The study reveals that most of the growers are having intercrops between the coconut trees, in large or very small scale even if the yield is lowand needs more space. For the soil moisture conservation around the coconut palm, the majority of the growers use the simple and low-cost technique; mulching around the coconut palms. However, 30.1% of the growers were found to not use any technique to improve the soil moisture even when the drought is a frequent event in the country, but this more valid for small scale growers. To improve their yield, majority of the growers preferred and used CRISL recommended coconut fertilizer mixture (Adult Palm Mixture or APM) over the other commercially available fertilizer mixtures. Finally, the study shows that farmers with large estates are the most involved to follow training programs and apply the advices given by the CRISL.

The EXtreme PREcision Spectrograph (EXPRES) is a new Doppler spectrograph designed to reach a radial-velocity measurement precision sufficient to detect Earth-like exoplanets orbiting nearby, bright stars. We report on extensive laboratory testing and on-sky observations to quantitatively assess the instrumental radial-velocity measurement precision of EXPRES, with a focused discussion of individual terms in the instrument error budget. We find that EXPRES can reach a single-measurement instrument calibration precision better than 10 cm s−1, not including photon noise from stellar observations. We also report on the performance of the various environmental, mechanical, and optical subsystems of EXPRES, assessing any contributions to radial-velocity error. For atmospheric and telescope related effects, this includes the fast tip-tilt guiding system, atmospheric dispersion compensation, and the chromatic exposure meter. For instrument calibration, this includes the laser fRequency comb (LFC), flat-field light source, CCD detector, and effects in the optical fibers. Modal noise is mitigated to a negligible level via a chaotic fiber agitator, which is especially important for wavelength calibration with the LFC. Regarding detector effects, we empirically assess the impact on the radial-velocity precision due to pixel-position nonuniformities and charge transfer inefficiency (CTI). EXPRES has begun its science survey to discover exoplanets orbiting G-dwarf and K-dwarf stars, in addition to transit spectroscopy and measurements of the Rossiter–McLaughlin effect.

We report the detection of a Saturn-size exoplanet orbiting HD 332231 (TOI 1456) in light curves from the Transiting Exoplanet Survey Satellite (TESS). HD 332231—an F8 dwarf star with a V-band magnitude of 8.56—was observed by TESS in Sectors 14 and 15. We detect a single-transit event in the Sector 15 presearch data conditioning (PDC) light curve. We obtain spectroscopic follow-up observations of HD 332231 with the Automated Planet Finder, Keck I, and SONG telescopes. The orbital period we infer from radial velocity (RV) observations leads to the discovery of another transit in Sector 14 that was masked by PDC due to scattered light contamination. A joint analysis of the transit and RV data confirms the planetary nature of HD 332231 b, a Saturn-size (

), sub-Saturn-mass (

) exoplanet on a 18.71 day circular orbit. The low surface gravity of HD 332231 b and the relatively low stellar flux it receives make it a compelling target for transmission spectroscopy. Also, the stellar obliquity is likely measurable via the Rossiter–McLaughlin effect, an exciting prospect given the 0.14 au orbital separation of HD 332231 b. The spectroscopic observations do not provide substantial evidence for any additional planets in the HD 332231 system, but continued RV monitoring is needed to further characterize this system. We also predict that the frequency and duration of masked data in the PDC light curves for TESS Sectors 14–16 could hide transits of some exoplanets with orbital periods between 10.5 and 17.5 days.

Recent years have seen increasing interest in the characterization of sub-Neptune-sized planets because of their prevalence in the Galaxy, contrasted with their absence in our solar system. HD 97658 is one of the brightest stars hosting a planet of this kind, and we present the transmission spectrum of this planet by combining four Hubble Space Telescope transits, 12 Spitzer/IRAC transits, and eight MOST transits of this system. Our transmission spectrum has a higher signal-to-noise ratio than those from previous works, and the result suggests that the slight increase in transit depth from wavelength 1.1–1.7 μm reported in previous works on the transmission spectrum of this planet is likely systematic. Nonetheless, our atmospheric modeling results are inconclusive, as no model provides an excellent match to our data. Nonetheless, we find that atmospheres with high C/O ratios (C/O ≳ 0.8) and metallicities of ≳100× solar metallicity are favored. We combine the mid-transit times from all of the new Spitzer and MOST observations and obtain an updated orbital period of P = 9.489295 ± 0.000005, with a best-fit transit time center at T
0 = 2456361.80690 ± 0.00038 (BJD). No transit timing variations are found in this system. We also present new measurements of the stellar rotation period (34 ± 2 days) and stellar activity cycle (9.6 yr) of the host star HD 97658. Finally, we calculate and rank the Transmission Spectroscopy Metric of all confirmed planets cooler than 1000 K and with sizes between 1 R
⊕ and 4 R
⊕. We find that at least a third of small planets cooler than 1000 K can be well characterized using James Webb Space Telescope, and of those, HD 97658b is ranked fifth, meaning that it remains a high-priority target for atmospheric characterization.
Global Circulation of the Open Magnetic Flux of the Sun
Authors: Fisk L. A. , Kasper J. C.
Published: April 2020

The global circulation of the open magnetic flux of the Sun, the component of the solar magnetic field that opens into the heliosphere, and the consequences of the global circulation were proposed by Fisk and coworkers in the early 2000s. The Parker Solar Probe, on its initial encounters with the Sun, has provided direct confirmation of both the global circulation and the physical mechanism by which the circulation occurs, transport by interchange reconnection between open magnetic flux and large coronal loops. The implications of this confirmation of the global circulation of open magnetic flux and the importance of interchange reconnection is discussed.

Long-Term Vision Outcomes in Patients With DME and a Limited Early Visual Response to Ranibizumab in RIDE and RISE
Authors: Singh Rishi P. , Pieramici Dante J. , Wang Pin-wen , Gune Shamika
Published: April 2020

BACKGROUND AND OBJECTIVE:

To compare early and long-term visual responses to ranibizumab in patients with diabetic macular edema.

PATIENTS AND METHODS:

Retrospective analysis of RIDE (NCT00473382) and RISE (NCT00473330). Vision outcomes over 36 months were compared between limited early gainers (gained ≤ 5 Early Treatment Diabetic Retinopathy Study [ETDRS] letters), early 1-line gainers (gained 6 to 9 ETDRS letters), and early 2-or-more-line gainers (gained ≥ 10 ETDRS letters) at Month 3.

RESULTS:

Among 235 ranibizumab-treated patients, 42.6%, 20.0%, and 37.4% were limited early gainers, early 1-line gainers, and early 2-or-more-line gainers, respectively. At Month 36, 71.3% of limited early gainers achieved 6 to 9 and 10 or more ETDRS letter gains. Mean ETDRS letter scores at Month 36 were comparable between limited early gainers (67.8), early 1-line gainers (73.4), and early 2-or-more-line gainers (71.6).

CONCLUSION:

Clinically meaningful vision outcomes were achieved with long-term ranibizumab treatment, irrespective of early visual acuity response.

Comparison of Ocular Ultrasound Versus SD-OCT for Imaging of the Posterior Vitreous Status in Patients With DME
Authors: Pessoa Bernardete , Coelho João , Malheiro Luísa , José Diana , Pires Saúl , Coelho Constança , Figueira João , Meireles Angelina , Melo-Beirão João
Published: April 2020

BACKGROUND AND OBJECTIVES:

To assess the percentage of vitreous adherence to the posterior pole in patients with diabetic macular edema (DME) with ocular ultrasonography (US) and establish a comparison with spectral-domain optical coherence tomography (SD-OCT).

PATIENTS AND METHODS:

Cross-sectional consecutive analysis of patients followed in a diabetic retinopathy consultation. Vitrectomized eyes and patients with epiretinal membranes were excluded. A comparison between macular SD-OCT 20 × 20°, SD-OCT 55 × 35°, and ocular US for the vitreous status was performed. A subanalysis of the percentage of eyes with thickened posterior hyaloid and focal vitreous macular adhesion (VMA) was determined with SD-OCT 20 × 20° and SD-OCT 55 × 35°.

RESULTS:

From 78 eyes of 39 patients, 55 eyes were included. All patients had type 2 diabetes mellitus with a median duration of 20 years (range: 3 to 40 years); 60% were phakic, and 61.8% were male. Previous treatments included intravitreal injections in 54.5% eyes, macular laser in 67.3%, and panretinal photocoagulation in 56.4%. All eyes had a non-posterior vitreous detachment (PVD) status on US. The 55 × 35° SD-OCT detected a non-PVD status in 96.4% (100% in video display mode) and a VMA in 87.3%. The 20 × 20° SD-OCT only detected a VMA in 43.6% of cases, with a thickened posterior hyaloid in 40% and a focal VMA in 18.2%.

CONCLUSIONS:

In the authors' DME patients, vitreous adherence to the posterior pole was highly prevalent, with a total agreement between US and SD-OCT 55 × 35° video display mode. SD-OCT 20 × 20° is not an accurate method to diagnose VMA compared to SD-OCT 55 × 35°.

O CARÁTER INCLUSIVO DAS PRÁTICAS DE RECURSOS HUMANOS NAS ORGANIZAÇÕES: UM ESTUDO DE CASO NO SUL DE MINAS GERAIS
Authors: Palhares José Vitor , Souza dos Santos Ana Augusta Almeida de , Rosa Marina Estela Almeida , Santos Thiago Lima Bahia
Published: April 2020

O objetivo deste artigo foi analisar as práticas inclusivas de Recursos Humanos existentes em um hospital do sul de Minas Gerais, compreendendo tanto a percepção da gestora de RH como a das PcDs contratadas pela organização. Por meio de uma pesquisa qualitativa, de caráter descritivo, foram realizadas entrevistas semiestruturadas com seis PcDs e uma gestora de RH do hospital, e a análise dos dados foi feita por meio da Análise de Conteúdo. Constatou-se que as políticas de inclusão da organização estão mais presentes no discurso da gestora de RH do que nas práticas organizacionais. Nesse sentido, fica evidente a existência de um discurso politicamente correto, com pouca informação consistente a respeito das políticas e práticas de inclusão da instituição e caracterizado pelas divergências entre a realidade visualizada pela gestora e a realidade vivenciada pelas PcDs.

Co-Cr-Mo alloys is the material used as a biomedical implant in human body. This material is widely used because they have excellent in corrosion and wear resistance. In this study, microstructure and results of tensile test that were affected by carbon and nitrogen were investigated. The specimens of Co-Cr-Mo alloy were made by investment casting. The compositions of the alloys are Co-28Cr-6Mo-0.8(Si, Mn, Fe)-0,2Ni-(0.08-0.25)C-(0-0.2)N. After that process, microstructure of the alloys is characterized by, SEM/EDX and XRD testing using bulk and electrolytic extracted specimens. The mechanical properties were determined by tensile test. The precipitate content in as-cast alloys was higher when carbon and nitrogen was added. The main precipitate formed in the specimens with variations in carbon and nitrogen is M23X6 type, π-phase, χ-phase, and σ-phase. Carbon and nitrogen promoted M23X6 type and π-phase precipitation, respectively, meanwhile χ-phase was formed in the alloys with low carbon content. The addition of carbon and nitrogen shows an increased in yield strength, tensile strength and elongation of as-cast Co-28Cr-6Mo-0.8(Si, Mn, Fe)-0,2Ni-(0.08-0.25)C-(0-0.2)N alloys.

Stigma against people living with HIV (PLHIV) among health workers remains a barrier to the provision of needed care to HIV patients worldwide. We sought to investigate predictors of HIV stigma among health workers in Cape Coast, Ghana. This was a cross sectional study conducted in three hospitals from November 2016 to February 2017. The study made use of a pre-existing self-administered questionnaire. Multiple regression analysis and Pearson’s coefficient tests were performed to determine the relationship between the dependent variable, i.e. the stigmatized attitudes of health workers, and some independent variables, and to determine which of the independent variables predict stigma amongst health care workers. A total of 331 health workers of different categories participated. Respondents’ personal opinions on HIV, fears/worries of getting infected and category of staff {F(3,327)= 23.934 P0.00}, R2 = 0.180) significantly predicted their stigmatizing behaviour. Compared to other health workers, nurses had higher scores for stigmatizing behaviour. The study found evidence of discriminatory and stigmatizing behaviour towards PLHIV by health workers. Stigma reduction programmes aimed at health workers should be strengthened at all health facilities that provide care to PLHIV.
