Authors: Nurwidayati Anis , Purwanto Hari , Ambar Garjito Triwibowo , Roro Upiek Ngesti Wibawaning Astuti Raden
Published: April 2024

Malaria is a re-emerging vector-borne disease. Malaria is caused by Plasmodium parasites namely P. falciparum, P. malariae, P. vivax, P. ovale, and P. knowlesi. The parasite is transmitted by mosquitoes from the genus Anopheles. The genus Anopheles comprises more than 480 described species worldwide and many more are yet to be described. It is known that there are more than 100 species of Anopheles that can transmit malaria parasites to humans. The present review aims to assess studies on the biodiversity of Anopheles as a malaria vector and its control in Indonesia. The results showed that a total of 80 species of Anopheles mosquitos are reported in Indonesia, and at least 31 species of Anopheles mosquitoes have been reported as malaria vectors in Indonesia. Several efforts to decrease the number of malaria cases are the distribution and wide-scale use of Long-Lasting Insecticide Treated Bednets (LLIN), Indoor Residual Spraying (IRS) applications, larvae control, and environmental management. Vector control and entomological surveillance of malaria are one of the main domains for achieving malaria elimination. In conclusion, a combination of national policies, local-specific, habitat-specific, and community participation approaches are needed for effective malaria vector control in Indonesia.

Authors: Mahajan Tushar , Tangri Amanpreet
Published: April 2024

The inherent swelling and shrinking tendencies of clayey soil limit its applicability in subgrade construction. To address this issue and contribute to sustainable development, an experiment was conducted to explore the use of powdered LDPE plastic waste for stabilizing clayey soil. Various proportions of LDPE waste powder were added to the soil, revealing that a 4% LDPE waste powder content significantly increased the soil’s strength. Statistical analysis demonstrated a robust correlation between LDPE powder proportion, maximum dry unit weight, ideal moisture content, and unconfined compressive strength of the soil. Remarkably, the soil sample containing plastic waste outperformed the traditional sample, suggesting that integrating plastic waste with clayey soil is an effective strategy to enhance soil quality while concurrently reducing plastic waste through proper disposal. This study highlights a promising approach for sustainable subgrade construction Sand environmental waste management.

Published: April 2024

In recent years, the field of green synthesis for carbon dots has seen significant advancements in the development of materials for heavy metal ion sensing applications. A variety of eco-friendly and sustainable approaches have been explored to synthesize carbon dots (CDs) with enhanced sensing properties. These materials have shown great promise in detecting heavy metal ions due to their high sensitivity, selectivity, and low detection limits One of the key advancements in this area is the utilization of natural sources such as biomass, organic waste, and plant extracts as precursors for the synthesis of CDs. These green precursors not only contribute to the sustainable nature of the synthesis process but also result in the production of carbon dots with unique surface chemistry and optical properties. In addition to the synthesis and functionalization strategies, the understanding of the underlying mechanisms governing the interaction between CDs and heavy metal ions has advanced significantly. This improved understanding has facilitated the design of CDs with tailored sensing capabilities and improved overall performance. Overall, the recent progress in the green synthesis of CDs for heavy metal ion sensing holds great promise for the development of cost-effective, environmentally friendly, and high-performance sensing platforms with potential applications in environmental monitoring, industrial safety, and healthcare diagnostics.

Authors: Chhillar Monika , Kukkar Deepak
Published: April 2024

The escalation of industrial activities over the past century has significantly heightened human exposure to heavy metals, posing grave threat to the health as well as the environment. Cadmium, mercury, and lead are few of the many heavy metals. They are prevalent pollutants and are absorbed, retained, and accumulated within the human body. On the basis of the absorbed dosage, exposure route, and duration, the range of the toxicity fluctuate. While these metals are essential in limited quantities, excessive exposure can lead to severe health complications and disorders. This review examines the mechanisms and adverse effects of cadmium, mercury, and lead on human health when present in exceedingly large amounts.

Published: April 2024

Bioremediation is term define to utilise different living organisms for reducing the toxic impacts of contaminants. There are numerous of contaminants in the environment with their persistence and bioaccumulation abilities. These contaminants involved heavy metals, dye disposals, petroleum wastes, oil spills etc. Enzymes are biocatalysts that are responsible for hydrolysing a particular reaction in a specific cell of living organisms. Enzymes have been serving in various sectors for several years’ industries like pharmaceuticals, food, detergent, leather, paper, fabric, and many more. Despite various applications of biological or microbial enzymes, they are comparatively cheaper, stable, and reusable than chemical catalysts. Therefore enzyme-based reactions are preferable to chemical reactions in almost every industry. Proteases, amylases, and lipases are prioritized in the list of industrial enzymes cellulases. Microbial enzymes are attractive to researchers because of their high yield in comparison to chemical reactions. Enzyme applications are not restricted to industrial benefits but they are more eco-friendly than other chemical biocatalysts for example enzymes can reduce dye contaminants from the environment. Over chemical reactions, enzymes are the most suited replaceable candidate due to their agricultural significance. Hence this study will be involved in the comparison of biological catalysts so Enzymes are better options instead of chemical components. Therefore, in this review we will discuss different approach for the degradation for various contaminants with microbes.
Variation in the Composition Properties and its Effect on the Mechanical Properties of a cortical bone
Authors: Kalsi Sachin , Singh Jagjit , Sharma N.K.
Published: April 2024

Cortical bone is a composite material with varying mechanical properties as per the anatomical locations, orientations, etc. The relationship between bone cortical composition properties and compressive mechanical strength is important for selecting the right scaffold material. The findings show that the mineral content consisting mainly of hydroxyapatite crystals has a positive effect on the mechanical properties of the cortical bone, that is, an increase in the mineral content can increase the load capacity of the scaffold. According to this study, wet and dry densities equally impact the compressive strength and modulus of cortical bone. In addition, the presence of water degrades the quality of bone and reduces its ability to function, the variation in composition and its effect on mechanical properties must be considered when creating Scaffolds. The findings highlight the need to consider the properties of these composites when selecting scaffold materials for tissue engineering. The results of this study may help create biomimetic scaffolds with enhanced properties that support tissue regeneration and integration.

Authors: Gureeva E.V.
Published: April 2024

The work analyzes agroclimatic resources in the Non- Chernozem zone of Russia for the period from 1981 to 2023. As a result of studying the data array, it was established that the values of the sum of active temperatures in the agroclimatic subzones of the Non-Black Earth Region increased by 200-250°C, the amount of precipitation falling during the growing season decreased by 20-40 mm, the hydrothermal humidification coefficient (HTC) of Selyaninov decreased by 0.1- 0.3 p. The changes led to a shift of the isotherm of the sum of active temperatures by 150-200 km towards high latitudes. A grouping of years of research was carried out according to the hydrothermal coefficient, the yield and growing season of soybean variety Georgia were determined. As a result of the research, it was revealed that the highest average seed yield for the group of years (moistening conditions) was obtained in the year with sufficient moisture and amounted to 2.47 t/ha, and the lowest - 1.18 t/ha per year with insufficient moisture. A significant relationship has been established between seed yield, the weight of 1000 seeds and the HTC of the growing season: the variation in soybean yield during the years of research is 63% associated with the influence of factors: the weight of 1000 seeds and the HTC of May-August (R2 = 0.63). Thus, the recorded upward trend in the sum of active temperatures in the region for the crop is positive and contributes to the expansion of soybean crops in the Non- Chernozem zone of the Russian Federation.

Several studies have been conducted to reveal the impact of specific music on cognitive functions. However, the effect of music tempo of human intelligence still holds great potential for further research. The purpose of this research is to examine the influence of specific music tempos (adagietto, moderato, and assai) on the concentration levels of students at Diponegoro University during the study. This experiment uses the stroop task paradigm in a design experiment within the subject from August to September 2023. The study involved a total of 42 participants from the Industrial Engineering Department with four treatment conditions (no distraction, adagietto tempo, moderato tempo, and assai tempo). Data collection was carried out for each treatment at a 24-hour interval. Then, the result data for the three variables (accuracy, reaction time, & stroop effect) are analyzed. The results of the statistical analysis indicate a significant increase in reaction time with ρ < 0.05 (0.004 < 0.05). The post hoc test indicates a significant difference between non-music treatment and assai tempo with ρ < 0.05 (0.008 < 0.05). The tempo assai treatment resulted in higher reaction times compared to the no music treatment, with values of 772.826 ms and 665.489 ms, respectively.
A novel method for multiple targets localization based on normalized cross-correlation adaptive variable step-size dynamic template matching

Published: April 2024

The template matching method has been widely utilized in the defect detection of wafer surfaces. However, the traditional matching approaches are limited by illumination, noise, and deformation, which cannot meet the requirements of accuracy and robustness. In this paper, a novel multiple targets localization method, named Normalized Cross-correlation Adaptive Variable Step-Size Dynamic Template (NCC-AVSSDT) matching, is proposed to improve the accuracy and efficiency of image localization, which combines the advantages of NCC and AVSSDT. The AVSSDT method is utilized to dynamically adjust the scanning step size based on the NCC matching coefficients. This approach optimizes the scanning process, accelerating convergence toward the optimal matching position. Experimental results verify the accuracy and robustness of the proposed method under different conditions, especially when dealing with rotational variations and variations in noise textures. Therefore, NCC-AVSSDT can be used to perform multiple targets localization of chip image in nearly real-time. Three experiment types were used for comprehensive evaluations, including multiple targets, noise, and rotation angles. Experimental results show that NCC-AVSSDT is much better than the sequential similarity detection algorithm and mean absolute deviation methods in terms of multiple targets (0.667 vs 0.811 s, 0.832 s) and success rate (100% vs 35%, 20%).
Celebrating organizational history triggers social identity threat among Black Americans
Authors: Wallace Laura E. , Reeves Stephanie L. , Spencer Steven J.
Published: April 2024

Many mainstream organizations celebrate their historical successes. In their history, however, they often marginalized racial minorities, women, and other underrepresented groups. We suggest that when organizations celebrate their histories, even without mentioning historical marginalization, they can undermine belonging and intentions to join the organization among historically marginalized groups. Four experiments demonstrate that Black participants who were exposed to an organization that celebrated their history versus the present showed reduced belonging and intentions to participate in the organization. These effects were mediated by expectations of biased treatment in the organization. Further, when organizations had a history of Black people in power, celebrating history was no longer threatening, highlighting that the negative effects of celebrating history are most likely when organizations are or are assumed to be majority-White and have treated Black Americans poorly. Taken together, these findings suggest that emphasizing organizational history can be a source of social identity threat among Black Americans.

Bacteriophages (phages) play critical roles in modulating microbial ecology. Within the human microbiome, the factors influencing the long-term coexistence of phages and bacteria remain poorly investigated. Saccharibacteria (formerly TM7) are ubiquitous members of the human oral microbiome. These ultrasmall bacteria form episymbiotic relationships with their host bacteria and impact their physiology. Here, we showed that during surface-associated growth, a human oral Saccharibacteria isolate (named TM7x) protects its host bacterium, aSchaalia odontolyticastrain (named XH001) against lytic phage LC001 predation. RNA-Sequencing analysis identified in XH001 a gene cluster with predicted functions involved in the biogenesis of cell wall polysaccharides (CWP), whose expression is significantly down-regulated when forming a symbiosis with TM7x. Through genetic work, we experimentally demonstrated the impact of the expression of this CWP gene cluster on bacterial–phage interaction by affecting phage binding. In vitro coevolution experiments further showed that the heterogeneous populations of TM7x-associated and TM7x-free XH001, which display differential susceptibility to LC001 predation, promote bacteria and phage coexistence. Our study highlights the tripartite interaction between the bacterium, episymbiont, and phage. More importantly, we present a mechanism, i.e., episymbiont-mediated modulation of gene expression in host bacteria, which impacts their susceptibility to phage predation and contributes to the formation of “source-sink” dynamics between phage and bacteria in biofilm, promoting their long-term coexistence within the human microbiome.
Po-éthique et écocritique
Authors: Novén Bengt , Bjørnerud Mo Gro
Published: April 2024

L’existence d’un nouvel âge géologique (l’anthropocène) associée à l’impact de l’homme sur la terre attire de plus en plus de chercheurs, aussi des sciences humaines. La notion d’anthropocène amène entre autres à une réflexion morale au sujet des actions de l’homme. La parole poétique de Ponge et de Char est précisément associée à la déontologie. Notre examen écocritique et po-éthique s’oriente vers les liens entre poésie et action, vers la poésie comprise comme dénonciation et accusation, mais aussi comme guide et enseignement. « L’habitation poétique » de la Terre (Hölderlin et Heidegger) chez ces deux poètes renvoie à une « leçon » qui ne se définit ni comme utopie, ni comme nostalgie ou recueillement méditatif, mais comme responsabilité et sensibilisation à tout élément constitutif du monde et de la nature.
What do we know about translators’ job satisfaction?
Authors: Ruokonen Minna , Svahn Elin
Published: April 2024

This article is an exploratory overview of research on translators’ job satisfaction (JS). We analyze the data (51
articles) for indications of (1) translators’ overall JS; (2) associations of overall JS with individual, job-intrinsic,
job-extrinsic, societal, and background factors; (3) translators’ satisfaction with job-intrinsic, job-extrinsic, and
societal aspects of their work. Translators’ overall JS in the data is fairly high, and it is linked to emotional intelligence,
the nature of translating, autonomy, interpersonal relationships, status perceptions, working mode, gender, and experience. The
translators studied are mostly happy with the job-intrinsic aspects, but their views on extrinsic and societal aspects are more
divided. Gaps in research include individual factors (e.g., self-efficacy, personality traits), background factors (e.g., cultural
and socio-economic differences), and the interaction of the different types of factors.

These operating conditions exhibit high CO2 conversions (up to 90%) at low energy efficiencies (2%–7.4%), due to direct electron impact dissociation driving the conversion process resulting in splitting of CO2 into CO and metastable oxygen atoms. The TALIF measurements yield spatially resolved translational temperatures between

Authors: Arsyad M , Hasaniyah S , Susanto A
Published: April 2024

The aims of this study were to analyze the value of dominant frequency and amplification, estimate the thickness of the sediment, and to evaluate the seismic vulnerability of the Rammang-Rammang Maros Karst Area. This work was carried out at the Rammang-Rammang Maros Karst Area, Salenrang and Bontolempangan Village, Bontoa District, Maros Regency, South Sulawesi. Microtremor data were analyzed using the Horizontal to Vertical Spectra Ratio (HVSR) method to obtain the H/V curve representing the dominant frequency and amplification values. The dominant frequency values were obtained in the range from 1.389 to 6.251 Hz. The amplification values were in the range from 0.455 to 3.944. The sediment thickness was obtained in the range from 18.521 to 88.029 m, and the seismic vulnerability was in the range from 0.040 to 5.761. High values of sediment thickness were obtained in riverbank areas, which indicated that the weathering that occurred was caused by weathering of limestone and sedimentation by rivers. Meanwhile, low sediment thickness values were obtained in karst hill areas, indicating that the weathering occurred due to the limestone dissolution process. Based on the seismic vulnerability and amplification, the Rammang-Rammang Maros Karst Area is in a relatively safe zone.

Bituminous grade coal is a promising and cost-effective raw material for supercapacitor electrode application. Carbonization plays a crucial role in transforming the organic components present in raw coal into a carbon-rich structure with an enhanced capacity for charge storage. In this research, we study carbonized bituminous coal (CBC) as a preliminary evaluation of its electrochemical properties. The carbonized bituminous coal was synthesized through a simple heat treatment at temperatures of 700 and 900°C under a continuous flow of argon gas for 2 hours. The structural behavior of carbonized bituminous coal was analyzed using several characterizations, including x-ray diffraction (XRD), Fourier transform infrared (FTIR), and Raman spectroscopy. Furthermore, the electrochemical properties were evaluated using cyclic voltammetry (CV) and galvanostatic charge-discharge in a 3 M electrolyte solution of potassium hydroxide (KOH) with a three-electrodes configuration. The specific capacitances of 49.75 F g−1 and 20.00 F g−1 at a current density of 0.5 A g−1 were achieved for the sample produced at the carbonization temperature of 700 and 900°C, respectively. These values are considerably higher than the specific capacitance of raw bituminous coal (0.687 F g−1) at 0.5 A g−1. This result may offer valuable insight for the further development of coal-based supercapacitor electrodes.

We developed the All-Sky Camera using a CMOS sensor, which is integrated with various other supporting devices to optimize image and video recordings. In general, CMOS cameras are not equipped with a cooling system, which can cause increased noise. Therefore, our design is equipped with an external cooling system to keep the temperature stable at night or during the day. In addition, our designs are also equipped with various other sensors, such as rain sensors, cloud sensors, light sensors, and sensors for environmental conditions such as pressure, temperature, and humidity. The development of the All-Sky Camera will also be used as a tool to monitor the sky throughout Indonesia with the Indonesian Sky Patrol Network (https://allskycam.or.id/). As a result, we managed to record several astronomical phenomena, such as meteors and space debris. For future scientific needs, the all-sky camera that we have developed is also used to monitor changes in light pollution and identify sources of light pollution, as well as the quality of the atmosphere at the ITERA Lampung Astronomical Observatory Environment (OAIL).

This research aims to synthesize zinc oxide nanoparticles using Terminalia catappa leaf extract. The synthesis method used Terminalia catappa leaves as a reductor. Synthesized ZnO nanoparticles were characterized using UV-vis, XRD, SEM, and TEM. UV-vis spectroscopy of samples showed peak absorption in the 300-380 nm range. The results of XRD characterization show that the ZnO nanoparticles crystal structure is hexagonal wurtzite, where the highest peak of reflection occurs at the reflection angle 2θ=36.24 of the crystal plan (101). SEM characterization results refer to flower-shaped morphology with a size distribution between 392-423 nm. These findings reveal morphology insight into the photocatalytic of ZnO nano-flowers for the environment.

The application of metal nanoparticles in medicine and optoelectronic devices recently has shown remarkable results. In the application of biosensor, metal nanoparticles are functionalized by the used of organic materials such as thiol-derivatives and citrate because of their high affinity to metal such as gold and silver also those organic material is dispersed in water that can be applied directly to bio-materials. Herein, we present the optimization study of capping molecules Trisodium citrate and 3-mercaptopropionic acid (3-MPA) on silver nanoparticles (AgNP) by used of modified chemical reduction and exchange ligand methods to form stable AgNP. The optimization of AgNP was done by varying the ratio among the concentration of the precursor (AgNO3), reducing agent and capping materials. Our colloidal AgNP products show bright yellow to yellow-brownish colour with the plasmonic peak for citrate capped AgNP (Ag-Citrate) at 410-424 nm, 3-MPA capped AgNP (Ag-MPA) by direct method at 428-440 nm, and 3-MPA capped AgNP (Ag-MPA) by ligand exchange method at 436-462 nm. The chemical characteristics of our Ag-citrate and Ag-MPA show the differences coordination of COO- between free citrate or 3-MPA and after citrate or 3-MPA capped on Ag. In our experiment, the TEM images for both samples of AgNPs show the spherical shape with the range of diameter size 5-38 nm which depends on the given ratio of material concentration in the synthesis process. Our AgNP solution results with the open capping of citrate or 3-MPA then can be applied as probe sensor for plasmonic sensor application.

Published: April 2024

Many properties of the spin–½ kagome Heisenberg antiferromagnet remains controversial and receiving continuous attention from theorists and experimentalists due to their fascinating magnetic properties and high heterogeneity coax by the geometrical frustration. In this research we seek and compare the results obtained in our recent article [1] with that of Napel[2] where we elucidate some of the identified magnetic behaviour using the spin–½ Heisenbeg model with the application of Exact Diagonalization and classical Monte-Carlo simulation on three site dimer and 3D simple cubic lattice simulation. The results obtained shows excellent agreement in both papers reviewed with [1] establishing firmly the FM to AFM transition, having a clear transition point referred to mixed phased [2].
Utilizing Convolutional Autoencoder for Anomaly Detections in LIGO Spectrogram Data
Authors: Imran Adrian Ramadhana
Published: April 2024

Massive amounts of data generated from the continuous running of LIGO gravitational-wave detectors comes with a need to search for signals within the data. Gravitational-wave data captured by the detector consist of astronomical events or glitches that last seconds. We present an unsupervised learning using convolutional autoencoder trained on the no-glitch Gravity Spy dataset to do anomaly search on spectrogram data. Reconstruction error is used as the basis and multiple windows are used to improve the model. Results on test data show that the model is capable of detecting signals with significant anomalies such as the Chirp or Koi Fish glitch. Meanwhile, detecting subtle anomalies such as the 1400 Hz Ripples is difficult because its reconstruction error is near the range of noise signals. Validating the result on confirmed gravitational-wave signals shows that the model is capable of gravitational-wave detection.
A comparison of the neutron detection efficiency and response characteristics of two pixelated PSD-capable organic scintillator detectors with different photo-detection readout methods

Published: April 2024

We characterize the performance of two pixelated neutron
detectors: a PMT-based array that utilizes Anger logic for pixel
identification and a SiPM-based array that employs individual pixel
readout. The SiPM-based array offers improved performance over the
previously developed PMT-based detector both in terms of uniformity
and neutron detection efficiency. Each detector array uses
PSD-capable plastic scintillator as a detection medium. We describe
the calibration and neutron efficiency measurement of both detectors
using a 137Cs source for energy calibration and a 252Cf
source for calibration of the neutron response. We find that the
intrinsic neutron detection efficiency of the SiPM-based array is
(30.2 ± 0.9)%, which is almost twice that of the PMT-based
array, which we measure to be (16.9 ± 0.1)%.
Non-inertial interpretation of the Dirac oscillator
Authors: Marrocco Michele
Published: April 2024

Non-inertial physics is seldom considered in quantum mechanics and this contrasts with the ubiquity of non-inertial reference frames. Here, we show an application to the Dirac oscillator which provides a fundamental model of relativistic quantum mechanics. The model emerges from a term linearly dependent on spatial coordinates added to the momentum of the free-particle Dirac Hamiltonian. The definition generates peculiar features (mutating vacuum energy, non-Hermitian momentum, accidental degeneracies of the spectrum, etc). We interpret these anomalies in terms of inertial effects. The demonstration is based on the decoupling of the Dirac equation from the stereographic projection that maps the 3D geometry of the dynamical problem to the complex plane. The decoupling shows that the fundamental mechanical model underpinning the Dirac oscillator reduces to the representation of the oscillator in the rotating reference frame attached to the orbital angular momentum. The resulting Coriolis-like contribution to the Hamiltonian accounts for the peculiarities of the model (mutating vacuum energy, form of the non-minimal correction to the momentum, classical intrinsic spin and gain of its quantum value, accidental degeneracies of the energy spectrum, supersymmetric potential). The suggested interpretation has an interdisciplinary character where stereographic geometry, classical physics of the Coriolis effect and quantum physics of Dirac particles contribute to the definition of one of the few exactly soluble models of relativistic quantum mechanics.

A liquid Li divertor is a promising alternative for future fusion devices. In this work a new divertor model is proposed, which is processed by 3D-printing technology to accurately control the size of the internal capillary structure. At a steady-state heat load of 10 MW m−2, the thermal stress of the tungsten target is within the bearing range of tungsten by finite-element simulation. In order to evaluate the wicking ability of the capillary structure, the wicking process at 600 °C was simulated by FLUENT. The result was identical to that of the corresponding experiments. Within 1 s, liquid lithium was wicked to the target surface by the capillary structure of the target and quickly spread on the target surface. During the wicking process, the average wicking mass rate of lithium should reach 0.062 g s−1, which could even supplement the evaporation requirement of liquid lithium under an environment > 950 °C. Irradiation experiments under different plasma discharge currents were carried out in a linear plasma device (SCU-PSI), and the evolution of the vapor cloud during plasma irradiation was analyzed. It was found that the target temperature tends to plateau despite the gradually increased input current, indicating that the vapor shielding effect is gradually enhanced. The irradiation experiment also confirmed that the 3D-printed tungsten structure has better heat consumption performance than a tungsten mesh structure or multichannel structure. These results reveal the application potential and feasibility of a 3D-printed porous capillary structure in plasma-facing components and provide a reference for further liquid−solid combined target designs.

In the design realm of fusion power supplies, structural components play a pivotal role in ensuring the safety of fusion devices. To verify the reliability of the converter structure design at the Comprehensive Research Facility for Fusion Technology (CRAFT), meticulous analysis of the converter's dynamic impact is carefully performed based on the worst fault current (400 kA), firstly. Subsequently, the thermal stress analysis based on the maximum allowable steady-state temperature is finished, and the equivalent thermal stress, thermal deformation, maximum shear stress of a single bridge arm and the whole converter are studied. Furthermore, a simple research method involving the current-sharing characteristics of a bridge arm with multi-thyristor parallel connection is proposed using a combination of Simplorer with Q3D in ANSYS. The results show that the current-sharing characteristics are excellent. Finally, the structural design has been meticulously tailored to meet the established requirements.
