Abstract
A novel powder modification method based on the simultaneous softening and agglomeration of steel powders via heat treatment in a rotary tube furnace has been investigated as a means to improve the cold sprayability of H13 tool steel powder. By adjusting starting powder size and shape as well as heat treatment conditions (maximum temperature, cooling rate, and atmosphere), cold spray of H13 powder went from virtually no deposition to the production of thick dense deposits with a deposition efficiency of 70%. Powder agglomeration, surface state, microstructure evolution, and softening are identified as key factors determining powder deposition efficiency and resulting deposit microstructure.

Abstract
This study assesses the quality of flame-sprayed alumina coatings produced from recently developed alumina cord using argon and compressed air as atomizing gases. Coatings of different thicknesses were deposited on aluminum substrates and then analyzed using optical microscopy, X-ray diffraction, and resistivity measurements. The coatings, particularly those sprayed with argon, had fine microstructure and higher surface and volume resistivity than flame-spray coatings made from alumina cord in the past. They were also found to have higher alpha phase content than plasma-sprayed coatings, regardless of the atomizing gas used. The effect of humidity and the possible formation of aluminum hydroxides are also addressed.

Abstract
Hydroelectric turbines are strongly affected by cavitation and the damage it can cause to critical part surfaces and profiles. The study of thermal spray processes and materials is thus relevant to improving turbine performance. The main objective of this work is to evaluate the influence of fuel-oxygen ratio on tungsten- and chromium-carbide cermet coatings deposited by HVOF. Particle velocity and temperature were measured as were coating hardness, porosity, and cavitation resistance. Higher particle velocities were obtained at higher fuel ratios, producing harder, denser coatings with better cavitation resistance. Based on test results, the wear mechanism starts with the nucleation of the cavitation that occurs in the pores, resulting in the formation of craters and the eventual detachment of lamellae as indicated by the smoothness of the surface.

Abstract
High-velocity oxyfuel (HVOF) sprayed coatings of Cr3C2-NiCr containing solid lubricants such as nickel cladded graphite and hexagonal boron nitride were successfully developed and characterised with the aim of optimizing their friction and wear behaviour. HVOF technology was used for the integration of solid lubricants to achieve strong cohesion between particles while minimizing thermal decomposition. Coating microstructure and composition were measured and correlated to the results of tribological and corrosion tests. The integration of the solid lubricant greatly reduced friction and wear volume at room temperature, but the lubricating effect was highly dependent on atmosphere and temperature. Cr3C2-NiCr with hBN, however, tends to exhibit more stable wear resistance over a wider temperature range and can be used at temperatures beyond 450 °C.

Published: September 2021

Modelling soil organic matter dynamics requires reproducible and accurate data from several methods that follow such evolution based on changes in soil organic matter properties. The objective of this study is to investigate changes in the chemical, thermal and biological properties of soil organic matter after afforestation using emerging methods such as thermal analysis, isothermal calorimetry, and </span><sup>13</sup><span>C CPMAS NMR. These methods were applied to a chronosequence of soils where large losses of carbon have occurred in the 29 years since afforestation. Results show that over this period the soil organic matter becomes more aromatic, resulting in increased thermal stability and decreased microbial activity. Over longer time frames, between 29 and 40 years after afforestation, soil organic matter increased, mainly in the aliphatic and carbohydrate fractions with enhanced thermal stability and consequent metabolic changes from microbial adaptation to the new organic matter.
Changes in soil microbial activity and physicochemical properties in agricultural soils in Eastern Spain

Agricultural land management greatly affects soil properties. Microbial soil communities are the most sensitive and rapid indicators of perturbations in land use and soil enzyme activities are sensitive biological indicators of the effects of soil management practices. Citrus orchards frequently have degraded soils and this paper evaluates how land management in citrus orchards can improve soil quality. A field experiment was performed in an orchard of orange trees (<em>Citrus Sinensis</em>) in the Alcoleja Experimental Station (Eastern Spain) with clay-loam agricultural soils to assess the long-term effects of herbicides with inorganic fertilizers (H), intensive ploughing and inorganic fertilizers (P) and organic farming (O) on the soil microbial properties, and to study the relationship between them. Nine soil samples were taken from each agricultural management plot. In all the samples physicochemical parameters, basal soil respiration, soil microbial biomass carbon, microbial indexes (BSR/C, Cmic/C and BSR/Cmic) and enzymatic activities (urease, dehydrogenase, ß-glucosidase and acid phosphatase) were determined. The results showed significant differences between the different agricultural management practices for the microbial properties and soil microbial indexes, since these were strongly associated with the soil organic matter content. Unlike herbicide use and intensive ploughing - management practices that both showed similar microbial soil properties - the organic management practices contributed to an increase in the soil biology quality, aggregate stability and organic matter content.

Published: September 2021

Due to widespread and fast-growing urban developments, large amounts of industrial, agricultural, and municipal wastewaters are produced which can change ecosystem functions after being released into rivers and lakes. The distributions of organic carbon (OC) and total phosphorus (TP) of soil were studied in the salt affected soils in the Meyghan Playa, Iran, to show the impacts of human activities on these soils and sediment properties in this arid region of the world. Samples were taken from 250 points and were analyzed geostatistically for electrical conductivity (EC), pH, TP, and OC. Although EC had the highest coefficient of variation (CV = 2.4) compared to CVs of the other soil properties, the sill/nugget ratio for EC in the geostatistical analysis was the highest one. Therefore, EC had the strongest spatial dependence compared to OC, TP, and pH with lower sill/nugget ratios and moderate spatial dependence. The maximum amount of OC was more than 2% which was observed near the entrance of municipal wastewater to the Meyghan Lake, and the highest soil TP was more than 400 kg mg<sup>-1</sup> near the entrance of municipal wastewater and also at river mouths, which can be attributed to leaching and runoff fertilizers from farmlands. Enrichment of OC in the entrance of municipal wastewater toward the lake is related to eutrophication and higher plant production.
Effect of organic amendments and sulfur on chemical and biological properties of a sodic soil

Published: September 2021

Saline soils cause concern in the productive systems of arid and semi-arid regions of the planet, since they cause a decrease in crop yield due to the osmotic effect, the presence of excess exchangeable Na which causes degradation of the soil structure, and the effect of the specific ion (Na, Cl, B) that can cause toxicity and imbalances in the nutrition of plants. Therefore, it is necessary to look for management alternatives to improve the productivity of these soils. To this end, we evaluated the effect of the application of <em>Prosopis juliflora</em> green manure (GM), palm oil residue vermicompost (VERM) and mineral sulfur (S°), on the chemical and biological properties of a Typic Haplustept sodium soil cultivated with <em>Zea mays</em>, using 3 t of organic matter ha<sup>-1</sup> of GM or VERM and 1.4 t ha<sup>-1</sup> of S° as unique treatments or mixed applications. The biological properties of soil microbial biomass (BMS), soil microbial respiration (RMS) and the activity of the enzymes phosphatases (alkaline and acid), protease and hydrolytic activity of the soil through the hydrolysis of fluorescein diacetate (FDA) were determined; as well as some chemical properties of the soil associated with sodicity. The effect on the biological properties of the soil depended on the type of amendment used and its composition, due to the differences found between treatments. In general, the application of organic amendments positively affected the RMS, BMS and the hydrolytic activity of the soil, while the application of S° increased the BMS but decreased the RMS and the enzymatic activity of phosphatases, proteases and hydrolases. The chemical variables studied also showed significant differences between treatments, with the presence of S° presenting significant differences in the greatest number of variables. In conclusion, applications of organic amendments mixed with S° positively affect the biological and chemical properties of sodium soils of the Colombian Caribbean region, since BMS is stimulated and sodium saturation is reduced.
Pharmacokinetic and Subjective Assessment of the JUUL System, Prototype JUUL2 Electronic Nicotine Delivery System in Two Nicotine Concentrations, IQOS and Combustible Cigarette
Authors: Goldenson Nicholas , Chen Joey , Shiffman Saul 
Published: September 2021

RATIONALE: Electronic nicotine delivery systems (ENDS) and heated tobacco products (HTP) are noncombustible alternatives for adult smokers. Evidence suggests sufficient nicotine delivery is necessary to facilitate switching away from smoking; nicotine delivery varies across ENDS within limited nicotine concentrations.

OBJECTIVES: To assess the nicotine delivery and subjective effects of currently-marketed US JUUL System (“JUUL”) ENDS, prototype JUUL2 ENDS in two nicotine concentrations, IQOS HTP and combustible cigarettes.

METHODS: Adult smokers (N=40) completed a 5-arm cross-over product-use laboratory confinement study. Nicotine PK and subjective effects were assessed following use of: (1) JUUL 59mg/mL nicotine; (2) JUUL2 Prototype 18mg/mL; (3) JUUL2 Prototype 40mg/mL; (4) IQOS HTP 18mg/g; (5) usual brand (UB) cigarette, each evaluated during _ad libitum_ (10 minutes) and controlled (5 minutes, 10 standardized puffs) use.

RESULTS: Nicotine delivery was greatest for UB cigarette, followed by JUUL2 Prototype 40mg/mL, IQOS, JUUL2 Prototype 18mg/mL, and JUUL 59mg/mL. Nicotine delivery from JUUL2 Prototype 18mg/mL was significantly greater than JUUL 59 mg/mL after _ad libitum_ use. JUUL products were significantly more satisfying and effective at reducing craving than IQOS. JUUL2 Prototype 40mg/mL was significantly more aversive than other JUUL products.

CONCLUSIONS: Currently-marketed JUUL 59mg/mL and prototype JUUL ENDS products were rated higher than IQOS on subjective measures associated with switching away from smoking. The JUUL2 Prototype 40mg/mL produced aversive responses, and requires modifications to be a viable product for adult smokers. Nicotine delivery and subjective responses to JUUL2 Prototype 18mg/mL suggest a product based on this prototype may facilitate increased switching among adult smokers.

Published: September 2021

Dalam arus globalisasi tidak dapat dipungkiri bahwa dunia perbankan menjadi salah satu dari sekian penggerak ekonomi suatu bangsa tak terkecuali Indonesia yang hampir sebagian besar dalam proses transaksinya melibatkan dunia perbankan. Namun demikian ditengah arus globasi juga banyak terjadi modus-modus baru dalam dunia kriminal, baik kejahatan secara umum, kejahatan dalam dunia maya atau Cyber Crime dan terakhir adalah kejahatan yang dilakukan pada dunia perbankan yang akhir-akhir ini menyita perhatian publik mengingat jumlah kasus serupa terus berkembang dari tahun ke tahun dengan modus yang berbeda-beda yang salah satunya adalah modus Operandi. Sehingga untuk mencegah terjadinya kasus ini secara terus menerus perlu dilakukan upaya pencegahan yang bersifat preventif. Dalam hasil penelitian ini penulis menawarkan empat hal guna menanggulangi tindak pidana perbankan. pertama, Perlunya peningkatan kemampuan penyidik dalam bidang akunting dan keuangan, kedua,peningkatan sistem pengawasan dari pihak bank yang lebih efektif dan ini bisa dilakukan jika proses rekruitmen pegawai lebih menekankan moralitas, ketiga,Perlunya kewenangan penyidik dalam rangka menjalankan tugasnya, bukan hanya sekedar menyangkut rahasia bank semata dan yang terakhir perlunya pembaharuan peraturan perundang-undangan dalam bidang perbankan
