Artikel ini bertujuan menganalisis kondisi sosial-ekonomi masyarakat Tatar Sunda pada abad ke-5 hingga abad ke-16. Metode yang digunakan adalah metode sejarah yang meliputi empat tahapan kerja, yaitu heuristik, kritik, interpretasi, dan historiografi.  Hasil dari kajian ini adalah bahwa wilayah Tatar Sunda memiliki potensi ekonomi yang  sangat tinggi. Hal ini dimungkinkan berkat faktor-faktor geografis. Tatar Sunda memiliki tanah yang sangat subur dan bisa ditanami oleh beragam jenis tanaman, termasuk tanaman ekspor yang sangat laku di pasar internasional. Di samping itu, wilayah Tatar Sunda pun cukup strategis karena memiliki banyak pelabuhan yang bisa dijadikan akses ke luar dan masuknya barang dan orang dari dalam dan luar Tatar Sunda.This article aims to analyze the socio-economic conditions of the Tatar Sunda community in the 5th to the 16th century.The method used is a historical method that includes four stages of work, namely heuristics, criticism, interpretation, and historiography.The result of this study is that the Tatar Sunda region has very high economic potential.This is possible because of geographical factors. Tatar Sunda has very fertile land and can be planted by various types of plants, including export crops needed on the international market.In addition, the Tatar Sunda region is also quite strategic because it has many ports that could be used as access to the outside and the entry of goods and people from inside and outside the Tatar Sunda.

Pakistan achieved high levels of Green Revolution Modern Variety (GRMV) adoption in the Green Revolution. Pakistan out-performed India and Bangladesh in the Green Revolution. Only China, among major countries, out-performed Pakistan in the Green Revolution. Pakistan does not have the food safety and environmental risk studies in place to support a regulatory environment for biotechnology. In effect, Pakistan is following the “precautionary principle” and applying it to science policy. This paper argues that this is a mistake. Pakistan is paying a “double penalty” for its inability to develop the regulatory systems required to take advantage of genetically modified (GM) crops. Not only does it lose the cost reductions enabled by GM crops, but because other countries have adopted GM crops, world prices are lower as a result and affect Pakistan’s export crops.

Predicting clinically significant prostate cancer (csPCa) is crucial in PCa management. 3T-magnetic resonance (MR) systems may have a novel role in quantitative imaging and early csPCa prediction, accordingly. In this study, we develop a radiomic model for predicting csPCa based solely on native b2000 diffusion weighted imaging (DWIb2000) and debate the effectiveness of apparent diffusion coefficient (ADC) in the same task. In total, 105 patients were retrospectively enrolled between January–November 2020, with confirmed csPCa or ncsPCa based on biopsy. DWIb2000 and ADC images acquired with a 3T-MRI were analyzed by computing 84 local first-order radiomic features (RFs). Two predictive models were built based on DWIb2000 and ADC, separately. Relevant RFs were selected through LASSO, a support vector machine (SVM) classifier was trained using repeated 3-fold cross validation (CV) and validated on a holdout set. The SVM models rely on a single couple of uncorrelated RFs (ρ < 0.15) selected through Wilcoxon rank-sum test (p ≤ 0.05) with Holm–Bonferroni correction. On the holdout set, while the ADC model yielded AUC = 0.76 (95% CI, 0.63–0.96), the DWIb2000 model reached AUC = 0.84 (95% CI, 0.63–0.90), with specificity = 75%, sensitivity = 90%, and informedness = 0.65. This study establishes the primary role of 3T-DWIb2000 in PCa quantitative analyses, whilst ADC can remain the leading sequence for detection.

With the advancement of technology in forestry, the utilization of advanced machines in forest operations has been increasing in the last decades. Due to their high operating costs, it is crucial to select the right machinery, which is mostly done by using productivity analysis. In this study, a productivity estimation model was developed in order to determine the timber volume cut per unit time for a feller-buncher. The Weibull distribution method was used to develop the productivity model. In the study, the model of the theoretical (estimated) volume distributions obtained with the Weibull probability density function was generated. It was found that the c value was 1.96 and the b value was 0.58 (i.e., b is the scale parameter, and c is the shape parameter). The model indicated that the frequency of the volume data had moved away from 0 as the shape parameter of the Weibull distribution increased. Thus, it was revealed that the shape parameter gives preliminary information about the distribution of the volume frequency. The consistency of the measured timber volume with the estimated timber volume strongly indicated that this approach can be effectively used by decision makers as a key tool to predict the productivity of a feller-buncher used in harvesting operations.

This study aims to evaluate the effects of camu-camu powder (CCP), Amazonian berry fruit with documented bioactive properties, physicochemical meat parameters, and the growth kinetics parameters of S. enterica ser. Typhimurium, psychrotrophic bacteria (PSY), and lactic acid bacteria (LAB) in vacuum-packed ground beef. Batches of ground beef were mixed with 0.0%, 2.0%, 3.5%, and 5.0% CCP (w/w), vacuum-packed as 10 g portions, and stored at 5 °C for 16 days. Centesimal composition analyses (only on the initial day), pH, TBARS, and color were quantified on storage days 1, 7, and 15, while PSY and LAB were counted on days 0, 3, 6, 9, 13, and 16. Another experiment was conducted with the same camu-camu doses by inoculating S. enterica ser. Typhimurium microbial kinetic curves were modeled by the Huang growth and Weibull decay models. CCP decreased TBARS in beef from 0.477 to 0.189 mg MDA·kg−1. No significant differences in meat pH between treated and control samples were observed on day 15. CCP addition caused color changes, with color a* value decreases (from 14.45 to 13.44) and color b* value increases (from 17.41 to 21.25), while color L* was not affected. Higher CCP doses caused progressive LAB growth inhibition from 0.596 to 0.349 log CFU·day−1 at 2.0% and 5.0% CCP, respectively. Similarly, PSY growth rates in the treated group were lower (0.79–0.91 log CFU·day−1) compared to the control (1.21 log CFU·day−1). CCP addition at any of the investigated doses produced a steeper S. enterica ser. Typhimurium inactivation during the first cold storage day, represented by Weibull’s concavity α shape parameter, ranged from 0.37 to 0.51, in contrast to 1.24 for the control. At the end of the experiment, however, S. enterica ser. Typhimurium counts in beef containing CCP were not significantly different (p < 0.05) from the control. Although CCP affects bacterial kinetics, it does not protect ground beef against spoilage bacteria and Salmonella to the same degree it does against lipid peroxidation.
