NOWCASTING REGIONAL ECONOMIC GROWTH IN INDONESIA

This study aims to nowcast gross regional domestic product at the provincial level for Indonesia. The dynamic factor model and mixed data sampling were applied to three sets of variables; namely, macroeconomic, financial, and Google Trends. We find that both methods captured several economic expansions and contractions, including the recent downturn during the COVID-19 pandemic. By including the pandemic period, accuracy across the same set of variables and provinces was slightly reduced.
STUDENTS' MATHEMATICS PROBLEM-SOLVING VIEWED FROM MATHEMATICS ANXIETY AND GENDER

Some internal factors influence problem-solving ability. Some internal factors that presumably influence problem-solving are mathematics anxiety and Gender. This study aims to determine problem-solving abilities regarding mathematics anxiety and Gender. It is a quantitative research that involves 66 students of a Junior High School in Yogyakarta. The sampling technique used is a simple random sampling technique. The instruments in this study were a problem-solving ability test and a mathematics anxiety questionnaire. The data analysis technique used is Two Way ANOVA. The results show differences in problem-solving ability regarding the students' mathematics anxiety levels. However, there was no difference in students' mathematical problem-solving abilities between male and female students. On the other hand, there is no difference in students' mathematical problem-solving abilities in terms of the level of mathematics anxiety and Gender.
Parasitic incidence in cultured and wild Nile tilapia (Oreochromis niloticus) in Makurdi, Benue State, Nigeria

Parasitic incidence in cultured and wild Nile tilapia (Oreochromis niloticus) in Makurdi, Benue State, Nigeria was investigated by standard parasitological techniques using 305 samples comprising 146 and 159 Oreochromis niloticus randomly purchased from the cultured (Ponds) and wild (Lower River Benue) environments, respectively. Nine (9) parasite species belonging to two (2) species each of crustacean (Argulus spp. and Ergasilus spp.), protozoa (Trichodina spp. and Ichyophthyirius multifilis), cestode (Ligula intestinalis and Bothriocephalus spp.) and a species of monogenea (Cichlidogyrus spp.), digenea (Clinostomum spp.) and nematode (Camallanus spp.) were recovered from the examined fish. All the parasites were present in both environments with the exception of I. multifilis that was recovered from the wild O. niloticus. Out of the 146 and 159 samples of cultured and wild O. niloticus, 81 and 62 samples each were infested with 128 and 93 ectoparasites and endoparasites, respectively. The overall prevalence (55.48%), mean intensity (1.58) and abundance (0.88) were higher for cultured O. niloticus compared to the overall prevalence (38.99%), mean intensity (1.50) and abundance (0.58) recorded for the wild O. niloticus. The prevalence and intensity of infection in most of the parasite species were higher (9.59 and 1.50, 7.53 and 1.36, 2.74 and 1.25, 2.05 and 3.33, 5.48 and 1.88, 2.05 and 2.33, respectively from the cultured environment; 6.92 and 1.45, 6.29 and 1.30, 1.26 and 0.50, 0.63 and 2.00, 2.52 and 1.25, 1.26 and 4.00, 3.14 and 1.60, 1.26 and 2.50, respectively from the wild) in females than the males (7.53 and 1.18, 5.48 and 1.13, 1.37 and 1.50, 1.37 and 3.00, 3.42 and 1.60, 0.68 and 2.00, respectively from the cultured environment; 6.29 and 1.20, 4.40 and 1.29, 0.63 and 3.00, 0.00 and 0.00, 0.00 and 0.00, 0.63 and 3.00, 2.52 and 1.25, 0.00 and 0.00, respectively from the wild). Ectoparasites of cultured and wild O. niloticus were more in the gills (114) compared to the skin (25) while endoparasites of cultured and wild samples of O. niloticus were more in the intestine (48) compared to the stomach (40). Parasite prevalence was higher in the bigger fish samples compared to the smaller ones.
Geometrical models for the high‐frequency dielectric properties of brine saturated sandstones

In the MHz–GHz range, geometrical effects associated with platy grains (e.g., clay particles in sandstones) are especially important in determining the complex dielectric function, e(ω), of rocks. We consider two classes of geometrical models based on rather different pictures for the spatial arrangement of the clay particles. In the bimodal model, spherical and platy grains (with a single aspect ratio) are randomly dispersed throughout the system while in the coated grain consolidation model the platy grains are confined to a thin layer at the pore grain interface. Calculations based on these models are compared with experimental data on five sandstones and the coated grain solidation model is generally found to be in better agreement. In sandstones exhibiting the strongest frequency dependence in e(ω), we find that a continuous distribution of platy grain aspect ratios is required to obtain a satisfactory fit to the experimental data. Such distributions are easily treated within the coated grain consolidation framework.
Amenability and uniformly continuous functionals on the algebras _{}() for discrete groups

In this paper, it is shown that for every discrete group G and 1 < p < oc, Ap(G) * PMp(G) is closed in PMp(G) if and only if G is amenable. Let G be a locally compact group, 1 < p < 0 and Ap(G) be the Herz-FigaTalamanca algebra consists of functions f on G which can be represented as f = EUn *vVn where Un E Lq(G), Vn E LP(G) (p+q-1 = 1) with El UnIlqIIVnI1p <00, with norm as the infimum of the last expression over all such representations of f. The space of multipliers of Ap(G) is denoted by MAp(G), i.e., MAp(G) = {U E C(G): uAp(G) C Ap(G)} , where C(G) is the space of bounded continuous functions on G. The norm of u in MAp(G) is IIUIlMAp = SUP{IlUVIAp: V E Ap(G), |V IIAP < 1}. Let CON Vp(G) denote the bounded linear operators on LP(G) which commute with translations from the right, equipped with operator norm. Let PFp (G) and PMp(G) be the norm closure and weak-star closure of L1 (G) in CON Vp(G) . It turns out that PMp(G) is just the Banach space dual of Ap(G) . It should be mentioned that A2(G) = A(G) is the Fourier algebra of G and PM2(G) = VN(G) is the von Neumann algebra of G; see [4]. There is a natural action MAp(G) on PMp(G): given u E MAp(G) and f E PMp(G), define u f as (u* f, v) = (f, uV) for all v E Ap(G). When G is discrete, every element of PMp(G) can be identified with a left convolution operator by a function of lP(G). So in this situation, the action is simply the pointwise multiplication of functions. The norm closure of Ap(G) * PMp(G) in PMp(G) is denoted by UCp(G) and it is called p-uniformly continuous functionals of Ap(G). The reader is referred to [9, 10] for more information of these spaces. As stated in [9], the space UCp(G) coincides with the PMp-norm closure of the set of T E PMp(G) with compact support (for the definition of support see [10]).

How does audit committee moderate the relationship between audit firm size, industry specialization, and the cost of equity capital? A comparison of the Ohlson and Capital Asset Pricing Model

The purpose of this study is to examine the moderation effect of the audit committee on the linkages between audit firm size, industry specialization, and the cost of equity capital with firm size and financial leverage as a control variable. This study is one of few that compared the accuracy of Ohlson and Capital Asset Pricing Model in explaining the cost of equity capital and the moderation role of the audit committee. A sample of 123 manufacturing firm-year observations was drawn from Indonesian-listed companies for five years period (2016-2020). The results show that while the audit committees significantly moderate the negative relationship between firm size on the cost of equity capital, there is no significant evidence of the moderation role of the audit committee on the relationship between industry specialization and the cost of equity capital using the Capital Asset Pricing Model. On the contrary, the moderation role of the audit committees on the effect of industry specialization toward the cost of equity capital under Ohlson was supported in the study. Further, it found that the Ohlson has a better performance than the Capital Asset Pricing Model in explaining the cost of equity capital as the Ohlson measurement expressed the role of earnings per share which represent a more real rate of return.
Prevalence of Tick-Borne Viruses from Ticks Breeding on Camels Imported to Egypt During the Period from January 2019 to April 2021

: Ticks show a vital role in the extent of diseases such as viral infection. Tick-borne viruses (TBVs) are a broad category with various genetic features transported by ticks. Specific TBVs are well-known for producing serious infections with high fatality ratios in humans and livestock, whereas others may cause community-health dangers that we don't yet understand. So, we aimed to detect TBVs isolated from ticks breeding on camels imported to Egypt during the period from January 2019 to April 2021. Throughout our study time, 27732 hard ticks were gathered from camels imported to Egypt to detect the existence of some medically important TBVs. Ticks were divided into pools (1385) each pool containing about 20 ticks. After that, tick pools were tested for the existence of Crimean–Congo hemorrhagic fever virus (CCHFV), Dugbe virus (DUGV), Phleboviruses , Alkhumra hemorrhagic fever virus (AHFV), and Thogoto virus (THOV) via real-time reverse transcription PCR (rRT-PCR) and nested RT-PCR. Three genera , Hyalomma (n = 25000 ticks; 90.1%), Rhipicephalus (n = 1236 ticks; 4.5%) and Amblyomma (n = 1496 ticks; 5.4%) were detected. The molecular analysis of both RT-PCR results showed that the CCHFV and AHFV were detected in 25/ 1385 tick pools (1.8%) and 14/1385 tick pools (1.01%), respectively. Herein, we indicated the presence of CCHFV and AHFV in Egypt and demonstrated the possibility of TB-dissemination of the virus. Additionally, further analysis on ticks and human samples are now recommended in epidemiological studies within the Egyptian land.
Modified mean-field potential approach to thermodynamic properties of a low-symmetry crystal: Beryllium as a prototype

We extend the mean-field potential (MFP) approach for evaluating the vibrational contribution of the lattice ion of high-symmetry metals, and present a modified MFP approach which can be applied to low-symmetry or complex structure crystals. Based on the modified MFP approach in which the effect of the structural parameters on the free energy is taken into account, a first-principles scheme for calculating thermodynamic properties of a crystal dependent on the crystal structure is developed. By taking hexagonal close-packed beryllium as a prototype, we demonstrate that our scheme is suitable for investigating the structural properties and equation of state of low-symmetry crystals.
Nuclear matter saturation point and symmetry energy with modern nucleon-nucleon potentials

We determine the saturation properties of nuclear matter within the Brueckner-Hartree-Fock approach based on a large set of modern nucleon-nucleon potentials and confirm the validity of the Coester band. The improvement of the saturation point when including nuclear three-body forces is pointed out and comparison with the Dirac-Brueckner-Hartree-Fock results is made.
HEURISTIC APPROACHES FOR LOADING PROBLEMS IN FLEXIBLE MANUFACTURING SYSTEMS

Flexible manufacturing systems (FMSs) are able to process a wide variety of operations, but the specific mix of operations that can be performed at any point in time depends upon the combination of tools loaded onto the machines. The machines have tool magazines with finite capacities. We consider the problem of assigning operations and their associated tools to machines (or groups of machines) to maximize the throughput for a specified steady-state mix of orders. Since this objective is difficult to deal with directly, we use an intermediate objective of meeting workload targets for each machine group as closely as possible. A certain form of this intermediate objective has been shown to correlate highly with the original objective. Since it is computationally intractable to find optimal solutions for problems with more than 20 operations, fast heuristic algorithms are developed. These algorithms are adapted from multi-dimensional bin-packing algorithms. Computational results are reported.
Effect of Pretreatment and C/N Ratio in Anaerobic Digestion on Biogas Production from Coffee Grounds and Rice Husk Mixtures

Indonesia has great potential in producing large quantities of renewable energy sources, such as biomass. Biogas is a renewable energy source produced from biomass. It is can be developed in agricultural countries producing rice and coffee, where a large amount of waste is produced in the form of rice husks and coffee grounds. This study examined the effect of physiochemical pretreatment and the C/N ratio on biogas production using coffee grounds and rice husk mixtures. Physical pretreatment was conducted by grinding the mixture up to 50 mesh size, followed by chemical pretreatment by soaking the mixture in 3% KOH; moreover, the variation in the C/N ratio was set at 25 and 30. Anaerobic bacteria were acquired from rumen fluid. The ratio of the coffee ground material, rice husks, and rumen fluid was 1:1:1. This research was conducted in duplicate under batch conditions at ambient temperature (25–35 oC)with a digester volume of 1.5 L. Biogas productivity was measured every 2 d for 60 d. The experimental results indicated that biogas production with a C/N ratio of 30 was 13.3–66.5% higher than that with a C/N ratio of 25. The inclusion of physical pretreatment at a C/N ratio of 30 increased biogas production by up to 31.3%. Moreover, the inclusion of a chemical pretreatment at a C/N ratio of 30 resulted in 30.3% higher biogas production. The kinetics model of biogas production showed that a C/N ratio of 30 with physical and alkaline pretreatment can produce maximum biogas yields of 6,619 mL and 6,570 mL, respectively. Overall, both pretreatments sequentially increased the biogas production significantly.
A coefficient estimate for nonvanishing H functions

The Krzyz conjecture asserts that if f(z) = oo + a\z + a>2Z 2 + ••• is a nonvanishing analytic function with l/l < 1 in |*| < 1, then \a n \ < 2/e (n = 1,2,.). Hummel, Scheinberg and Zalcman more generally conjectured that |a n | < (2/e)*/ 2 for all nonvanishing / 6 H p with ll/llp < 1(! /P + 1/g = 1,1 < p < oo). We prove the latter conjecture for n = 2 and n = 3 for a natural subclass of nonvanishing H p functions. We also point out a relationship between the two conjectures for this subclass. Our main tool in this investigation is the Pontryagin Maximum Principle.
A Continuum Theory of Superfluid Turbulence based on Extended Thermodynamics

Abstract A thermodynamical model of inhomogeneous superfluid turbulence previously formulated is extended in this paper to nonlinear regimes. The theory chooses as fundamental fields the density, the velocity, the energy density, and two extra variables, in order to include the specific properties of the fluid in consideration: the averaged vortex line length per unit volume and a renormalized expression of the heat flux. The relations which constrain the constitutive quantities are deduced from the second principle of thermodynamics using the Liu method of Lagrange multipliers. Using a Legendre transformation, it is shown that the constitutive theory is determined by the choice of only two scalar functions of the intrinsic Lagrange multipliers. The complete non-equilibrium expressions of the mass chemical potential, of the chemical potential of vortices, and of the entropy flux are determined: these relations are exact, because no approximation is used for their determination, and maintain their validity also for processes far from equilibrium.
Flow field and noise characteristics of a supersonic impinging jet

This paper describes the results of a study examining the flow and acoustic characteristics of an axisymmetric supersonic jet issuing from a sonic and a Mach 1.5 converging–diverging (C–D) nozzle and impinging on a ground plane. Emphasis is placed on the Mach 1.5 nozzle with the sonic nozzle used mainly for comparison. A large-diameter circular plate was attached at the nozzle exit to measure the forces generated on the plate owing to jet impingement. The experimental results described in this paper include lift loss, particle image velocimetry (PIV) and acoustic measurements. Suckdown forces as high as 60% of the primary jet thrust were measured when the ground plane was very close to the jet exit. The PIV measurements were used to explain the increase in suckdown forces due to high entrainment velocities. The self-sustained oscillatory frequencies of the impinging jet were predicted using a feedback loop that uses the measured convection velocities of the large-scale coherent vortical structures in the jet shear layer. Nearfield acoustic measurements indicate that the presence of the ground plane increases the overall sound pressure levels (OASPL) by approximately 8 dB relative to a corresponding free jet. For moderately underexpanded jets, the influence of the shock cells on the important flow features was found to be negligible except for close proximity of the ground plane.

EFFECT OF FOLIAR APPLIED AMINO ACIDS ON GROWTH CHARACTERISTICS OF OAT (AVENA SATIVA L.)

The progressive study on oat (Avena sativa L.) transpired during the crop season of 2021–2022 at the Agricultural Research Station, College of Agriculture, University of Basrah, Iraq. The study aimed to determine the effects of amino acids foliar application on two oat cultivars. Experimenting with a randomized complete block design included a split-plot arrangement. Two oat cultivars (Shafa and Genzania) grown and placed in secondary plates received seven treatments of three different amino acids (Control – No amino acid, 50 and 100 mg L-1 of L-Tryptophan, 50 and 100 mg L-1 of L-Glycine, and 50 and 100 mg L-1 of L-Lysine). The results revealed that oat cultivars and amino acid treatments differed significantly for most of the studied traits. The amino acid foliar application treatment of LTryptophan at the rate of 50 mg L-1 showed significant superiority, which boosted and provided the highest rate of flag leaf area, chlorophyll content, crop growth rate, and green fodder yield. However, the cultivar Shafa exhibited superiority for flag leaf area, chlorophyll content, and the green and dry fodder yield, with increased values of 7.15 cm2, 8.11 µg cm-3, and 8.01% and 5.61% t ha-1, respectively.
Attitudes of university colleagues toward accommodations for students with disabilities

This study aimed to assess attitudes of university colleagues toward accommodations for students with disabilities. This quantitative study used a cross-sectional observation design. The observation was designed via Qualtrics, distributed, and 247 those who took part in the investigation were investigated using a software package to analyze statistical data. Results indicated that most faculty demonstrate strong and great results in the provision of accommodations in the educational practice of students with. Furthermore, findings suggested issues surrounding disabled learners were much discussed by female university colleagues. Many years of experience were associated with great results in providing accommodations for students with disabilities in universities than inexperienced children. Being a training helper was also associated with a more optimistic perception toward discussing academic problems with disabled learners than being an Advisor. Recommendations are to provide training and role models for mans to increase their attitudes toward accommodations and to provide training and mentorship for those with less training experience.

An experimental and numerical study of channel flow with rough walls

A fully turbulent channel flow with smooth and rod-roughened walls has been investigated using hot-wire anemometry and direct numerical simulations (DNS). The mean flow follows the law of the wall for both surfaces and the velocity defect suggests that the outer layer is very little affected by the roughness. The Reynolds stresses appear to be very similar for the two surface geometries outside $y\,{\approx}\,5k$, where $k$ is the roughness height. A quadrant analysis shows that the structural differences close to the wall extend somewhat further out. The turbulence structure is further investigated using stress ratios and the anisotropy tensor, which corroborate the findings from the Reynolds stresses. Many of the recent investigations on boundary layers seem to find large differences between smooth and rough wall data in the outer layer also. A tentative explanation for the apparent dependence on flow type of the surface roughness effects is given.
Implementation of novel polygon‐based obfuscation methods to improve privacy of agricultural data

Geoprivacy protection is a significant concern when sharing data. To support sustainable land management by leveraging existing agricultural data, research is needed to identify how the polygon nature of static field parcels can be obfuscated to allow data sharing among individuals and organizations. In this study, five adaptive polygon‐based obfuscation methods including PN*Rand, PDonut‐k, PDensity‐k, PAHilb, and PDonut_AHilb methods were developed and applied on the Irish Nutrient Management Planning Online (NMP Online) agricultural dataset. The polygon‐based obfuscation methods introduced in this study were designed with the consideration of properties of spatial polygon objects including the spatial coordinates, shape and size of the polygon, topology, and spatial relationship between adjacent polygons that can be used to identify real‐world objects. These methods were developed to guarantee that there is no false‐identification and non‐unique obfuscation which is important for static polygon objects in terms of accuracy and privacy protection. Qualitative approaches were developed to identify the optimal values of inner and outer radii of donut shape based on k‐anonymity satisfaction and subsequently obtain the optimal value of k‐anonymity. Several evaluation methods were implemented to compare the methods performance. Density‐based methods particularly PDonut‐AHilb provide the best trade‐off between field parcel confidentiality and spatial pattern preservation and should be considered for researchers and practitioners obfuscating polygon data.
