Analisis Hujan Ekstrim Probable Maximum Precipitation (PMP) menggunakan metode Hersfield dan Perhitungan Debit Banjir
Authors: Akmal Akmal , Yulia Yulia , Aranda Aris
Published: May 2023

Extreme rain is rain with the lowest intensity of 50 mm/24 hours or 20 mm/hour. River is an elongated surface water flow and flows from a higher place (upstream) to a lower place (downstream). The area of KIuet is 1429.93 km and the area of Kluet River is 163.51 km2 and the length of the river is 68.26 km. The problem is that Kluet Utara River experiences high rainfall, resulting in overflows that flatten agricultural land and submerge residential areas. The purpose of the study was to calculate the planned return period rainfall, analyze the PMP (probable Maximum Precipitation) value and analyze the flood discharge to evaluate the PMF (Probable Maximum Flood) value and the return flood discharge. The benefits of this research are used to see the PMF value and return period rainfall to analyze the frequency of flooding KIuet Utara Watershed (DAS). The scope of the research was to calculate rainfall and flood discharge in KIuet Utara Watershed and secondary data which includes 10 years rainfall data obtained from BMKG (Meteorology, Climatology and Geophysics Agency) Indrapuri Aceh Besar and watershed maps obtained from PT. Mediatama Indoconsult. Processing of rainfall data on return period used Log Pearson III Method and PMP used Hersfield Method while calculating the planned flood discharge using Melchior Method. The results of the research is the rainfall value for the return period for the lowest rainfall in the 2 year return period is as high as 211,836 mm and the highest rainfall for the 1000 year return period is 566,239 mm, so that the flood discharge plan for the return period for the lowest flood discharge in the 2 year return period is equal to 2061,342 m3/s and the highest flood discharge at the 1000 year return period is 5510,490 m3/s. The PMP value was obtained at 2128,432 mm so that the PMF was obtained at 20714,772 m3/s. Log Pearson III and PMP methods can be used to calculate the rainfall in KIuet Utara and the results from the rainfall are used to calculate the planned flood discharge using Melchior Method.

Asphalt, also known as bitumen, is a mixture of binders used as road preservation. On the BTS road preservation project package. Central Aceh/Nagan Raya – Lhok Seumot – Jeuram (MYC) uses a thin layer of Asphalt Concrete as a treatment for road damage. Asphalt concrete thin layer is a hot asphalt mixture that can be used as a surface layer on road pavement which functions as a road preservation layer. The problem raised and also a research is how the feasibility of a thin layer of asphalt concrete on an incline. The method used in this study is based on testing Job Mix Asphalt, Traffic Counting, and direct observation of asphalt work in the field as well as supporting data in the form of information from consultants or contractors. Asphalt concrete thin layers cannot be used on incline lanes because the asphalt road contains a very fine aggregate mixture. Comparison of thin layers of asphalt concrete with AC – BC using the Traffic Counting method explains that vehicles passing on roads using thin layers of asphalt concrete on the dominant incline lane are more vehicles unable to climb compared to vehicles passing on roads using asphalt AC – BC. The use of a thin layer of asphalt concrete cannot be used for incline lanes, but a thin layer of asphalt concrete is highly recommended for the use of asphalt roads in urban areas.

A flare-up is defined as a pain and/or swelling of the soft tissues that occurs within a few hours or a few days following the root canal treatment. In some cases, the flare-ups can appear after the finishing of the root canal treatment, due to the penetration or development of the microorganisms into the root canal. The pain felt by the patient depends on the extent of the periradicular tissue injury, its severity and intensity of the inflammatory immune response. The article discusses the microbial irritation of apical periodontal tissue caused by insufficient instrumentation and filling of the root canals, factors that lead to failure of the outcome of root canals treatment.

The diffuse, unresolved sky provides most of the photons that the Hubble Space Telescope (HST) receives, yet remains poorly understood. The HST Archival Legacy program SKYSURF aims to measure the 0.2–1.6 μm sky surface brightness (sky-SB) from over 140,000 HST images. We describe a sky-SB measurement algorithm designed for SKYSURF that is able to recover the input sky-SB from simulated images to within 1% uncertainty. We present our sky-SB measurements estimated using this algorithm on the entire SKYSURF database. Comparing our sky-SB spectral energy distribution (SED) to measurements from the literature shows general agreements. Our SKYSURF SED also reveals a possible dependence on the Sun angle, indicating either nonisotropic scattering of solar photons off interplanetary dust or an additional component to zodiacal light. Finally, we update the diffuse light limits in the near-IR based on the methods from Carleton et al., with values of 0.009 MJy sr−1 (22 nW m−2 sr−1) at 1.25 μm, 0.015 MJy sr−1 (32 nW m−2 sr−1) at 1.4 μm, and 0.013 MJy sr−1 (25 nW m−2 sr−1) at 1.6 μm. These estimates provide the most stringent all-sky constraints to date in this wavelength range. SKYSURF sky-SB measurements are made public on the official SKYSURF website and will be used to constrain diffuse light in future papers.

We analyze clustering measurements of BOSS galaxies using a simulation-based emulator of two-point statistics. We focus on the monopole and quadrupole of the redshift-space correlation function, and the projected correlation function, at scales of 0.1 ∼ 60 h
−1 Mpc. Although our simulations are based on wCDM with general relativity (GR), we include a scaling parameter of the halo velocity field, γ

f
, defined as the amplitude of the halo velocity field relative to the GR prediction. We divide the BOSS data into three redshift bins. After marginalizing over other cosmological parameters, galaxy bias parameters, and the velocity scaling parameter, we find f
σ
8(z = 0.25) = 0.413 ± 0.031, f
σ
8(z = 0.4) = 0.470 ± 0.026, and f
σ
8(z = 0.55) = 0.396 ± 0.022. Compared with Planck observations using a flat Lambda cold dark matter model, our results are lower by 1.9σ, 0.3σ, and 3.4σ, respectively. These results are consistent with other recent simulation-based results at nonlinear scales, including weak lensing measurements of BOSS LOWZ galaxies, two-point clustering of eBOSS LRGs, and an independent clustering analysis of BOSS LOWZ. All these results are generally consistent with a combination of

= 1. We cannot rule out an unknown systematic error in the galaxy bias model at nonlinear scales, but near-future data and modeling will enhance our understanding of the galaxy–halo connection, and provide a strong test of new physics beyond the standard model.

We combine our dynamical modeling black-hole mass measurements from the Lick AGN Monitoring Project 2016 sample with measured cross-correlation time lags and line widths to recover individual scale factors, f, used in traditional reverberation-mapping analyses. We extend our sample by including prior results from Code for AGN Reverberation and Modeling of Emission Lines (caramel) studies that have utilized our methods. Aiming to improve the precision of black-hole mass estimates, as well as uncover any regularities in the behavior of the broad-line region (BLR), we search for correlations between f and other AGN/BLR parameters. We find (i) evidence for a correlation between the virial coefficient

Inégalités de genre dans l’aide aux proches dépendants
Authors: Banens Maks
Published: May 2023

Cet article présente les chiffres les plus récents concernant le caractère genré de l’aide aux proches dépendants et propose quelques pistes d’interprétation. Les données et observations sont issues de l’enquête Care (Drees, 2015) et de la post-enquête Pegase (Banens et al ., 2018). Les résultats sont contrastés. Les pratiques de l’aide – le fait d’aider ou non, la part de l’aide prise en charge – s’avèrent peu genrées, à l’exception notable des fils et filles de fratries mixtes. En revanche, les conséquences négatives de l’aide – fatigue, dépression, anxiété et autres troubles – sont très genrées, y compris là où les pratiques ne le sont pas. Il pourrait s’agir, du moins partiellement, d’un conflit entre rôle d’aidant et rôle de genre. De façon inattendue, le rôle d’aidant semble mieux convenir aux hommes qu’aux femmes, car représentant la force, la protection des faibles. L’homme aidant est héroïsé, la femme aidante rencontre de la compassion.
Le rôle des proches dans les plans d’aide de l’Apa à domicile
Authors: Dussuet Annie , Ledoux Clémence
Published: May 2023

Les plans d’aide élaborés par les agents et agentes des départements déterminent le montant de l’allocation personnalisée pour l’autonomie (Apa) à domicile. En donnant accès à des services payants, ils semblent a priori permettre un certain désengagement des proches aidants et aidantes. Une enquête de terrain réalisée auprès d’agents et agentes d’un département français en charge de l’élaboration de ces plans montre au contraire qu’ils tiennent compte de l’éventuelle intervention des proches et constituent ainsi, de fait, un cadre de répartition du travail d’aide entre proches et professionnelles. L’enquête permet aussi de comprendre les normes et principes des agents et agentes et pourquoi l’Apa n’aboutit pas à décharger les proches de leur fardeau, notamment en entretenant le principe selon lequel le travail d’aide et d’accompagnement serait un devoir et irait de soi pour les femmes, renforçant ainsi les inégalités entre les femmes et les hommes.

Le projet d’autonomie est interrogé à partir du parcours d’insertion professionnelle d’un adolescent en hôpital de jour. Cet article souligne les enjeux identificatoires d’un parcours de rétablissement « avant la lettre ». Il met en avant les notions de potentialités psychotiques et de compromis identificatoire. Il montre comment la notion de rétablissement s’inscrit dans un modèle social d’autonomie individuelle qui se retrouve dans le nouvel esprit du soin. Cela interroge la manière de concevoir les rapports de l’adolescent, de sa famille, de l’institution, et du social.

Unemployment risk, MPC heterogeneity, and business cycles
Authors: Cho Daeha
Published: May 2023

This paper uses an estimated Heterogeneous Agent New Keynesian (HANK) model to evaluate the quantitative importance of two channels in driving aggregate consumption fluctuations in the US: (i) precautionary savings against unemployment risk and (ii) MPC heterogeneity. I find that MPC heterogeneity is the dominant channel because a large fraction of households are close to the borrowing limit. The empirical average MPC target in HANK generates counterfactually volatile aggregate consumption, and thus makes it more difficult for the estimated model to match the persistence of the aggregate data, indicating an MPC puzzle. This is because the likelihood‐based estimation favors a low degree of nominal rigidity and responsive monetary policy in the HANK model to reduce the discrepancy between consumption volatility in the model and in the data. The low degree of nominal rigidity and responsive monetary policy reduce the persistence of endogenous variables in the model.
Risk aversion and information aggregation in binary‐asset markets
Authors: Filippin Antonio , Mantovani Marco
Published: May 2023

We investigate how risk aversion (RA) shapes the informative content of prices in an experimental asset market, where traders are sorted according to their RA. RA should induce steeper individual demands and, under its most common parametrizations, drive equilibrium prices closer to revealing the state. Results support the prediction on individual demands, but not the prediction on prices, which do not vary with RA and are close to the risk‐neutral benchmark. This purported conflict is due to traders, particularly the more risk‐averse ones, conveying into prices only part of their information.

Managing job burnout from workplace telepressure: A three way interaction
Authors: Setyaningrum Retno P. , Muafi Muafi
Published: May 2023

Orientation: The massive development of information, communication and technology (ICT) in the last decade has motivated companies to adopt it in their business. However, this becomes one of the pressures faced by employees, as it may lead to job burnout.Research purpose: To explore the influence of workplace telepressure on employee burnout by considering transformational leadership and perceived organisational support (POS) as moderators.Motivation for the study: The literature on how workplace telepressure affects job burnout still needs to be explored, and there is a need to examine the condition by which this relationship can be strengthened or weakened.Research approach/design and method: This study employs a quantitative approach with 388 employees of manufacturing companies in three provinces in Indonesia. The data processing is done using conditional process analysis with SPSS macro-PROCESS.Main findings: Workplace telepressure is positively related to higher levels of job burnout. Transformational leadership moderates the influence of workplace telepressure on job burnout. Finally, POS strengthens the moderating role of transformational leadership in workplace telepressure on job burnout.Practical/managerial implications: Managers must be aware that workplace telepressure can trigger job burnout among employees. Leaders need to apply a transformational leadership style, and organisations need to provide full support for employees.Contribution/value-add: This study builds a model of stress management, represented by job burnout, because of the existence of workplace telepressure by considering contextual factors that individuals can use as resources to regulate the pressure they feel on having to respond to ICT continuously in their work.
Towards a theology of human praxis: A proposal from liberation theologies in a neoliberal world
Authors: Castrillón Restrepo Jose F.
Published: May 2023

Neoliberalism is an anti-utopian and kind of patron–client theory that threatens not only the human utopian thought, and therefore the human praxis, but also the ‘conditio humana’. Therefore, this threat also challenges the current visions of praxis in contextual theologies. From a dialogue between the traditions of praxis present in Latin American liberation theology and black liberation theology, particularly from a renewed understanding of human relationships in terms of God’s grace and human spirituality-kenosis, it could be possible to overcome the ideological character of neoliberalism by offering some elements for the development of a human praxis oriented to the creation of possible worlds that reproduce the natural circuit of life and acknowledge the rising and dignity of the new subjects.Intradisciplinary and/or interdisciplinary implications: The critical analysis of the ideological character of neoliberalism implies an interdisciplinary approach that considers the contribution of Christian theology. From the inductive orientation of Latin American liberation theology and black liberation theology, this research proposes some theological elements to discuss the feasibility of a human praxis that orients the creation of possible worlds.

Authors: Li Xianjuan
Published: May 2023

INTRODUCTION: With the development of economy, the phenomenon of financial fraud has become more and more frequent. OBJECTIVES: This paper aims to study the identification of corporate tax report falsification. METHODS: Firstly, financial fraud was briefly introduced; then, samples were selected from CSMAR database, 18 indicators related to fraud were selected from corporate tax reports, and 13 indicators were retained after information screening; finally, the XGBoost algorithm was used to recognize tax report falsification. RESULTS: The XGBoost algorithm had the highest accuracy rate (94.55%) when identifying corporate tax statement falsification, and the accuracy of the other algorithms such as the Logistic regressive algorithm were below 90%; the F1 value of the XGBoost algorithm was also high, reaching 90.1%; it also had the shortest running time (55 s). CONCLUSION: The results prove the reliability of the XGBoost algorithm in the identification of corporate tax report falsification. It can be applied in practice.
Research on the Deployment Strategy of Big Data Visualization Platform by the Internet of Things Technology
Authors: Guangtao Zhang
Published: May 2023

INTRODUCTION: To improve the big data visualization platform's performance and task scheduling capability, a big data visualization platform is constructed based on Field Programmable Gate Array (FPGA) chip application power equipment.OBJECTIVES: This study proposes to combine a genetic algorithm and an ant colony scheduling (ACOS) algorithm to design a big data visualization platform deployment strategy based on an improved ACOS algorithm.METHODS: Firstly, big data technology is analyzed. Then, the basic theory of the ant colony algorithm is studied. According to the basic theory of ACOS and genetic algorithm, an improved ACOS algorithm model is constructed. The improved ACOS algorithm scheduler is compared with the other three schedulers. Under the same environment, the completion time of scheduling the same job and different task amounts are analyzed. The Central Processing Unit (CPU) utilization is analyzed when different schedulers have entirely different workloads. RESULTS: The results show that the constructed big data visualization platform based on the improved ACOS algorithm model has higher task scheduling efficiency than other schedulers and can greatly shorten the data processing time. The experimental results show that under the homogeneous cluster, the completion time of the improved ACOS algorithm generally lags the capacity scheduler and the fair scheduler. Under the heterogeneous cluster, the improved ACOS algorithm scheduler can reasonably allocate tasks to nodes with different performances, reducing the task completion time. When the number of completed tasks increases from 50 to 200, the time increases by 45s, and the completion time is shorter than other schedulers. The CPU utilization of different task volumes is the highest, and the utilization rate increases from 81% to 95%. CONCLUSION: The improved ACOS algorithm scheduler has the shortest data processing time and the highest efficiency. This work provides a specific reference value for optimizing the big data visualization platform's deployment strategy and improving the platform's performance.
Application of Wireless Sensor Network Integrated With 3-5g Technology in the Design Of Interactive Space in an Urban Landscape
Authors: Yanfang Zhang
Published: May 2023

INTRODUCTION: The conventional approaches of urban landscape design and planning cannot incorporate concepts into the complete planning processes for scenes, and they need to effectively, clearly, and coordinately convey the planning impacts of several systems and huge scenes. Virtual Reality (VR) is now a significant part of designing and planning urban landscapes because of the advancement of Wireless Sensor Networks (WSNs) and 5G technologies.
OBJECTIVES: This article discusses the current condition and importance of "Three-Dimensional (3D)" portrayed urban landscape design and planning by outlining and evaluating previous works, introducing roaming algorithms and establishing a 3D database, and developing virtual scene manipulation tools.
METHODS: In this approach, the 3D model CapsNet (Capsule Network) neural model is implemented to train the data and provide improved results by highlighting the interactive space in the urban landscaper. CapsNet can improve the computer vision tasks of VR and AR applications.
RESULTS: The results show that a 3D visualized system with the CapsNet model can quickly distribute a large amount of data through graphics, enabling experts to intuitively notice testing results or interactively process such findings. Additionally, VR provides designers with practical data processing impacts through smart drawing, comprehensive display, and timely reporting, significantly increasing design productivity and effectively facilitating design quality.

Purpose This retrospective study aimed to re-evaluate the effect of concurrent chemotherapy in patients with locally advanced nasopharyngeal carcinoma (NPC) in the era of intensity-modulated radiotherapy (IMRT).Materials and Methods A total of 498 patients who received neoadjuvant chemotherapy (NCT) combined with concurrent chemoradiotherapy (CCRT) or IMRT were retrospectively reviewed. The distribution of baseline characteristics was balanced using propensity score matching. Additionally, the results of NCT+IMRT and NCT+CCRT were compared using Kaplan-Meier survival analysis, and differences in survival rates were analyzed using the log rank test.Results There were no significant differences in overall survival (OS), progression-free survival (PFS), distant metastasis-free survival (DMFS), and local progression-free survival (LRFS) between the two groups. Patients were further categorized into risk subgroups based on pretreatment Epstein-Barr virus (EBV) DNA cutoff values using receiver operating characteristic curve analysis. There were no statistically significant differences in OS, PFS, DMFS, and LRFS between patients who received NCT+CCRT and NCT+IMRT in the high-risk group. In the low-risk group, although there were no differences between NCT+CCRT and NCT+IMRT in OS, PFS, and LRFS, patients who received NCT+CCRT had better DMFS than those who received NCT+IMRT.Conclusion Pretreatment EBV DNA level can be used to individualize concurrent chemotherapy for patients with locally advanced NPC. Patients with low pretreatment EBV DNA levels may benefit from concurrent chemotherapy, whereas those with high levels may not. Other treatment modalities need to be explored for high-risk patients to improve their prognosis.

Authors: Omopariola S.S. , Jimoh A.A.
Published: May 2023

The study was carried out to assess the suitability of sand available in South Western Nigeria for concrete production. Collected samples of sand were  tested in the laboratory to determine their physical properties. The properties considered are gradation, specific gravity, water absorption, moisture  content, bulking, and percentage silt content. The result of the sieve analysis indicates that while the gradation of some of the samples is within the  specified values specified in standards, others do not conform. The values of the coefficient of uniformity and coefficient of curvature is between the  range of 3.6 – 10 and 0.53 – 2.56 respectively. The values of the results of specific gravity, water absorption, the moisture content are within the range of  2.67 – 2.86, 0.67% – 2.04%, 0.75% – 3.17% respectively. Based on the fact that the result of the test on the properties of the samples tested are in  accordance with the specifications in relevant codes as discussed in the body of this work, it can be concluded that most of the samples are suitable for  concrete production while the gradation of some of the samples needed to be modified to conform to the required grading.

Published: May 2023

This work presents the nonlinear analysis of the dynamics of large strain deformation of subsea flowlines and jumpers conveying two-phase fluid.  Precisely, flexible pipes operating in the stated condition undergo large strain deformations. Thus, the known nonlinear deterministic model of the  system is solved using method of discretized perturbation. Precisely, this study obtained the nonlinear natural frequency of simply supported flexible  pipes modelled using the large strain deformation theory. Results show that both hardening and softening nonlinear behaviors are indicated for pipe  undergoing large strain deformation compared with deformations modelled with small strain theory. Thus, operational insights and parameters for  sustainable management of large strain deformed subsea flow lines and jumpers conveying two phase flow are made available.
Deep reinforcement learning for aircraft longitudinal control augmentation system

Control augmentation systems (CAS) are conventionally built with classical controllers which have the following drawbacks: dependence on domain  specific knowledge for tuning and limited self-learning capability. Consequently, these drawbacks lead to sub-optimal aircraft stability and performance  when exposed to time varying disturbances. Hence, to curb the stated problems; this paper proposes the development of a deep reinforcement learning  (DRL) pitch-rate CAS (qCAS), aimed at guaranteeing adaptive stability, pitch-rate control tracking and disturbance rejection across the longitudinal  dynamics of an aircraft. This stated aim was actualized by developing a CAS with a deep deterministic policy gradient (DDPG) agent. Subsequently, this proposed method was compared with two classical qCAS methods (a developed PID-aCAS and a benchmark PIqCAS obtained from literature). The results  show that the developed DDPG-qCAS method outperformed the classical methods in peak overshoot, referemce command tracking and disturbance  rejection as well as mean absolute error (MSE) and mean steady state error (MSSE). Hence, it can be inferred that it is important to apply artificially  intelligent controllers to the flight control systems of aircraft in order to achieve superior time response, control command tracking accuracy and  disturbance rejection.

Electrical energy is a scarce resource in most developing countries. This has prompted numerous research into ways in which commercially deployed  wireless communication technologies can be used to monitor, control and manage such energy. Analysis of many of such electrical energy management  systems reveal inherent complexities in their deployment and operation. This has therefore motivated the proposal of a remotely operated electrical  energy management system (ROEEMS). The proposed system is designed to manage electrical energy from three different sources such as commercial  grid, photovoltaic arrays, and portable generator, and give an output depending on requirements of its operator. ROEEMS has been designed to  overcome some challenges in existing systems such as system complexity and security demands (as is typical of Internet and server-based systems). The  proposed design allows ROEEMS to achieve a truly remote operation mode while requiring limited operator skills and a comparatively reduced cost of  installation and operation.

Published: May 2023

The ultimate aim of supply chain integration is to achieve effective external integration between firms in a supply chain, and the starting point for this  broad integration is intra-firm integration. However, the extent to which functional units/departments integrate within and amongst them and the  effectiveness of the integration is not fully understood. This paper reports the results of a study carried out in three purposively selected large construction organisations that operate at national level, with the aim of assessing the extent of, and the effectiveness of their intra-firm integration.  Descriptive statistics was used to analyse the data collected across the three organisations. Findings indicated that every department engaged in internal  integration practices (communication and information sharing, coordination and resource sharing, and organisational relationships) in varying  proportions, and the effectiveness of the practices equally varied amongst the departments. 47% of the departments indicated that the extent of  integration within and between them was high and effective, 22% indicated a moderate level and somewhat effective integration, while 31% indicated  that the extent of their integration was low and ineffective. It is concluded that internal integration, when effectively done within and across functional  units and departments, would enhance the internal operational efficiency and the external integrative capabilities that would increase competitive  performance of organisations.
Maintenance Scheduling Algorithm for Transformers in Tanzania Electrical Secondary Distribution Networks
Authors: Mbembati Hadija , Ibwe Kwame , Maiseli Baraka
Published: May 2023

The drive by the government of Tanzania to electrify every village has resulted into expansion of the electrical secondary distribution networks (ESDNs). Therefore, maintenance management is of the highest priority for the smooth operation of the ESDNs to reduce unscheduled downtime and unexpected mechanical failures. Studies show that condition-based predictive maintenance (CBPdM) method allows the utility company to monitor, analyze and process the information obtained from ESDNs transformers. Thus, this study adopts the CBPdM method to develop a maintenance scheduling algorithm that can predict the transformer state, forecast maintenance time based on transformer load profile and schedule its maintenance using a knowledge-based system (KBS). Applying the challenge driven education approach, the requirements for developing an algorithm were established through an extensive literature survey and engagement of the key stakeholders from the Tanzania utility company. Our study uses the Dissolved Gas Analysis tool to collect the transformer parameters used in algorithm design. The parameter analysis was performed using Statistical Package for Social Sciences software. Results show that the designed KBS algorithm minimizes human-related maintenance errors and lowers labour costs as the system makes all the maintenance decisions. Specifically, the proposed maintenance scheduling algorithm reduces downtime maintenance costs by 1.45 times relative to the classical inspection-based maintenance model while significantly saving the maintenance costs.

Measurement of Solar Irradiance for Determining the Optimal Tilt Angle for Photovoltaic Panels
Authors: Olatona Gbadebo I. , Fadairo Tolulope J.
Published: May 2023

The challenge of solar panel installers in determining the tilt angle needed to obtain optimal performance from the photovoltaic panels was the focus of this paper. The performances of two 150 W panels under varied conditions of temperature and solar irradiance on a plane at two different heights (1 m and 11.5 m) from the ground surface were determined to find the effects of tilt angle and altitude on their performances. Measurements of solar irradiance, temperature, open-circuit voltage, and short circuit current were made at various tilt angles and compared to one another based on the measured irradiance. The optimal tilt angle at the experimental site was found to be 15°SW (165°). At this angle, the irradiance was 818.05 Wm–2 compared to 792.26 Wm–2 at 15°NE (15°), 780.44 Wm–2 45°NE (45°) and 767.63 Wm–2 at 45°SW(135°) at 1 m from ground surface, while at 11.5 m the irradiance at 15°SW was 861.99 Wm–2 compared to 685.98 Wm–2 at 15°NE, 624.33 Wm–2 at 45°NE and 676.49 Wm–2 at 45°SW. Hence the performance of a photovoltaic panel solely depends on the tilt angles relative to the height at which the panel is mounted.

Published: May 2023

The illegal wildlife trade problem is worldwide in scope, affecting biodiversity conservation and human wellbeing. However, the trade has cultural dimensions. In addition to economic gain, cultural influences drive the illegal wildlife trade. This paper examines the cultural drivers of illegal trade in vultures in southwestern Nigeria, a pressing but understudied example which is believed to be a major driver of population declines in West Africa. Semi-structured interviews revealed that Yoruba communities in southwestern Nigeria have practiced belief-based use of wildlife for generations, with participation in vulture trade passed vertically within families and horizontally between unrelated persons. Vulture products are used for a range of purposes, from healing to spiritual protection or good fortune. The cultural beliefs underlying use of vultures have a strong syncretic religious component and evolved from primordial myths based on the behavioural and morphological characteristics of vultures. We propose potential interventions that include re-establishing existing social norms that forbid the killing of vultures and engaging religious leaders to discourage trade.
Chewing lice (Insecta: Phthiraptera) found on Griffon Vultures (Gyps fulvus) from a wild breeding colony in central Spain.
Authors: Talabante Carlos , Bernal Iván
Published: May 2023

The Griffon Vulture (Gyps fulvus) is a social species which breeds in colonies and feeds in groups. This can facilitate horizontal transmission of ectoparasites between conspecifics. In 2015, in the province of Guadalajara, Spain, 28 vultures from a wild population were examined for ectoparasites, 24 of which were parasitized by chewing lice (Phthiraptera). Three species of lice were identified: Laemobothrion (Laemobothrion) vulturis, Colpocephalum turbinatum and Falcolipeurus quadripustulatus. Data on the prevalence and richness of louse species in the vulture population are also presented.

The New South Wales Heritage Act Review: a misdirected inquiry with a questionable purpose
Authors: Gehri Kirk Daniel
Published: May 2023

The New South Wales (‘NSW’) government published a discussion paper in April 2021 to encourage debate prior to commencing a review of the Heritage Act 1977 (NSW) ‘Heritage Act’. The paper had three key themes: making heritage easy, putting heritage to work and making heritage relevant. An inquiry into the review was referred to the Legislative Council Standing Committee on Social Issues. Multiple public submissions to the standing committee criticized the government’s policy themes for having failed to include guiding principles for the Heritage Act, those being: to protect, conserve and celebrate the State’s cultural heritage. The National Trust (NSW) has sought that any future amendments to the Heritage Act result in better heritage outcomes, rather than a weakening of heritage protection. First, this article suggests that the NSW Government has misallocated the State’s resources by conducting a review of the Heritage Act, when many stakeholders have suggested the architecture of the Act is highly workable. Secondly, reform of the National Parks and Wildlife Act 1974 (NSW) (‘NPWA’) is long overdue, as NSW remains the only State in Australia that still manages indigenous heritage through flora and fauna legislation. Thirdly, it is of concern that the Environmental Planning and Assessment Act 1979 (NSW) (‘EPAA’) can override any protection afforded under the Heritage Act if the project is deemed to be ‘State Significant Development’ (‘SSD’). The consequences arising from the Heritage Act review are important for all those who wish to preserve treasured older-style buildings and green space in NSW.
