Approximate scaling formula for ion–ion mutual neutralization rates

A complex potential model is used to treat the mutual neutralization of positive and negative ions. The model is used to examine neutralization by the charge transfer mechanism and also by internal excitation leading to capture. It is found that electron transfer is the dominant process for simple ions and small hydrated ions. The numerical results of the theory have been parameterized in terms of the reduced mass of the collision and the electron affinity of the electron donor. This procedure yields an approximate scaling formula that fits a wide range of experimental data to an accuracy of about ±30%.
In Situ XAS and XRD Studies on the Formation of Mo Suboxides during Reduction of MoO3

Reduction of MoO3 with hydrogen (5−100 vol %) in the temperature range from 573 to 823 K was studied by in situ X-ray diffraction and X-ray absorption spectroscopy. The experiments performed focused on elucidating phase composition and evolution with time under isothermal as well as temperature-programmed reduction conditions. At reaction temperatures below 698 K, the reduction of MoO3 to MoO2 is a one-step process without the formation of crystalline intermediates. At reduction temperatures above 723 K and H2 concentrations higher than 10 vol %, Mo metal is the final product of the reduction of MoO3. In addition, at temperatures higher than 698 K, the formation of Mo4O11 was observed. However, Mo4O11 is not an intermediate in the reduction of MoO3 but is being formed in a parallel reaction from MoO3 and MoO2 at temperatures above 698 K. It is shown that Mo4O11 can be obtained from a reaction of MoO3 and MoO2 at temperatures above 773 K, affording the same phase ratio of monoclinic and orthorhombic Mo4O11.
Polymetallocenylenes-Recent Developments

Abstract The polymetallocenylenes represent a class of macromolecular compounds in which units of a metallocene complex are directly and difunctionally interconnected so as to constitute a linear chain.This chapter represents an account of recent progress in the synthesis and spectroscopic characterization of the only two types of poly-metallocenylene known to this date, viz. poly-1,11-ferrocenylene (obtained with Mn up to 10 000) and poly-1,1′-ruthenocenylene (obtained in the oligomer range). In addition, the partial oxidation of poly-1,1′-ferrocenylenes, which gives poly(1,1′-ferrocenylene-co-1,1′-ferricenylene) structures possessing mixed-valence characteristics, is treated, and a discussion is presented of potential applications for these organometallic polymer types and expected future developments in the polymetallocenylene field.
RS EVALUASI KETAHANAN BEBERAPA GENOTIPE HASIL PERSILANGAN BLEWAH (Cucumis melo var cantalupensis) DENGAN MELON (Cucumis melo) TERHADAP HAMA KUMBANG DAUN (Aulacophora sp.)

Tanaman blewah merupakan salah satu tanaman yang memiliki kekerabatan yang sangat dekat dengan tanaman melon. Buah ini kurang diminati karena kadungan gula buah yang rendah dan dianggap nilai ekonomisnya masih rendah sehingga tidak dibudidayakan secara komersial, melainkan hanya sebagai tanaman sampingan. Di samping memiliki kekurangan, tanaman blewah memiliki beberapa keunggulan, yaitu daging buahnya yang segar, lembut dan kulit buah yang tipis, ukuran dan bentuk buah yang bervariasai, serta lebih tahan terhadap hama dan penyakit. Tanaman melon (Cucumis melo L.) merupakan salah satu tanaman buah-buahan yang digemari oleh masyarakat.

Thermophysical Characterization of Genipap Pulp

The influence of temperature and water content on thermophysical properties (density, thermal diffusivity, thermal conductivity and specific heat) of genipap (Genipa americana, L) pulp at medium maturity were studied. The thermophysical properties were determined at concentrations between 6.0% m/m and 24.0% m/m of water content and temperatures range of 5 to 80°C. The density decreased with increase in temperature and water content, while the thermal diffusivity and conductivity increased as temperature and water content increased. The specific heat decreased with the moisture content. Empirical models were fitted to the experimental data for each property and the accuracy of those models was checked.
In situ and laboratory determined first-order degradation rate constants of specific organic compounds in an aerobic aquifer

In situ microcosms (ISM) and laboratory batch microcosms (LBM) were used for determination of the first-order degradation rate constants of benzene, toluene, o-xylene, nitrobenzene, naphthalene, biphenyl, o- and p-dichlorobenzene, 1,1,1-trichloroethane, tetrachloromethane, trichloroethene, tetrachloroethene, phenol, o-cresol, 2,4- and 2,6-dichlorophenol, 4,6-o-dichlorocresol, and o- and p-nitrophenol in an aerobic aquifer. All aromatic hydrocarbons were degraded in ISM and LBM experiments. The phenolic hydrocarbons were all degraded in ISM experiments, but some failed to degrade in LBM experiments. Chlorinated aliphatic hydrocarbons were degraded neither in ISM nor LBM experiments. Degradation rate constants were determined by a model accounting for kinetic sorption (bicontinuum model), lag phases, and first-order degradation. With a few exceptions, lag phases were less than 2 weeks in both ISM and LBM experiments. First-order degradation rate constants for aromatic and phenolic hydrocarbons ranged betwee.
Ionic Synergistic Inhibition between the Cationic Gemini Surfactant and Anionic Surfactant for Steel Corrosion in 1M Hydrochloric Acid

The inhibitive synergistic effect between a cationic gemini surfactant, 1,2-ethane-bis(dimethyl dodecylammonium bromide) (designed as 12-2-12), and anionic surfactant, sodium dodecyl sulfonate (SDS) for the corrosion inhibition of A3 carbon steel in 1 mol L-1 HCl was investigated by weight loss. The inhibition system composed by 12-2-12 and SDS is efficient. The adsorption mechanism of the 12-2-12 and SDS on steel in acidic medium is discussed on the basis of experimental data and an adsorption model is proposed. Adsorption of inhibitor system on the A3 carbon steel surface in acidic medium obeys Langmuir’s adsorption isotherm.
Emergency Disbursements During COVID-19: Regulatory Tools for Rapid Account Opening and Oversight

More than 100 countries have launched emergency cash disbursement programs to alleviate financial hardships for individuals and households in light of the COVID-19 pandemic. Many of these programs are based in digital payments; however, a lack of official identification, mobile data services and the difficulties in face-to-face interactions restrict potential users from a standard customer due diligence process. Guidance from the Financial Action Task Force (FATF), the global anti-money laundering standards-setting body, encourage the use of innovative solutions for customer onboarding, specifically the risk-based approach and simplified due diligence (SDD). This paper summarizes the range of practice across jurisdictions that have employed a combination of SDD (also known as tiered CDD), licensing of non-bank financial institutions, and digital identification to enroll unbanked individuals into financial accounts so that they could receive COVID-19-related relief cash transfers. As this note concludes, jurisdictions that had adopted such practices were able to quickly ramp-up disbursement programs, bringing tens of millions of beneficiaries into the formal financial system. This report provides an analysis of varied SDD implementations and provides considerations for financial regulators looking to promote appropriate risk mitigation while digitally delivering emergency financial assistance.
Implementasi Metode Failover Pada Jaringan Software-Defined Network

Jaringan SDN memiliki banyak kelebihan juga memiliki beberapa masalah, salah satu nya yaitu link failure atau adanya jalur yang terputus pada saat pengiriman data antar host. Komunikasi antara data plane dan control plane diperlukan untuk mendeteksi, menghitung, dan menyisipkan rule yang menciptakan jalur baru. Komunikasi antara data plane dengan control plane ketika pembangunan rute baru dilakukan menimbulkan terjadinya latency atau waktu tunda-antara saat link failure terjadi, hal ini juga berdampak pada semua paket yang berpotensi hilang saat terjadi link failure. Pembangunan rute baru harus dilakukan agar paket dapat diteruskan ke data plane. Pada tugas akhir ini menerapkan mekanisme failover pada jaringan SDN dengan menggunakan fitur reactive forwarding dan algoritma Dijkstra pada controller ONOS dan diterapkan pada topologi, dan parameter uji jaringan yang berbeda. Metode ini menerapkan dua skenario pengujian yang dilakukan yaitu mekanisme failover dengan menggunakan reactive forwarding dan menggunakan algoritma Dijkstra. Masing-masing skenario dilakukan dengan menerapkan pada dua jenis topologi, yaitu 2-D Mesh dan Full-Mesh Dari percobaan dapat diperoleh bahwa dengan mekanisme failover, masalah jalur yang terputus dapat teratasi karena adanya jalur cadangan (secondary path). Terdapat perbedaan nilai Round Trip Time (RTT), nilai round trip time cenderung lebih besar pada skenario dengan menggunakan reactive forwarding. Perbedaan nilai round trip time dikarenakan pada scenario dengan algoritma dijkstra, jalur pengiriman ditentukan oleh ukuran bandwidth terbesar dan pada reactive forwarding ditentukan oleh hop count terkecil. Hasilnya, dengan menggunakan algoritma Dijkstra pada saat bandwidth yang berbeda tiap link dapat menurukan nilai round trip time sehingga latency menjadi lebih singkat.

Glycine and lysine adsorption and reactivity on the surface of amorphous silica

In order to better control the adsorption of proteins on mineral surfaces, it is useful to gain a thorough understanding of the behaviour of their constituting monomers, namely, amino acids. We have therefore investigated the adsorption of glycine, lysine, and other small biomolecules on well-characterised surfaces of silica. While similar systems have been studied before, these studies usually concentrated on evidencing the effect of surfaces on peptide bond formation in a phenomenological, mostly macroscopic approach. In contrast, we have considered the adsorption process from the view-point of the surface, using knowledge previously gained on the molecular identification of surface functional groups to better characterise their interaction with amino acids, both from the aqueous phase and from the vapour phase. We combined macroscopic level information such as adsorbed amounts, pH dependence, or TGA, with molecular characterisation by vibrational spectroscopies and 13 C NMR of the adsorbed molecules. In parallel, we have carried out molecular modelling of candidate clusters containing the amino acid and the adsorption site by DFT. The structures of lowest energy were also those that best reproduced the observed spectroscopic properties. Different adsorption mechanisms can be postulated, corresponding to different spectroscopic signatures of the amino acid/adsorption site complexes. On silica surfaces, this implies cooperative hydrogen bonding in a kind of molecular recognition. The existence of molecular recognition is also evidenced by experiments on the coadsorption of different amino acids, where strong selectivity effects may be observed. Such phenomena may have much practical significance in the fields of biofilms and prebiotic chemistry.
The Use of Solid‐Phase Synthesis Techniques for the Preparation of Peptide–Metal Complex Conjugates

This microreview summarizes recent reports on the preparation of metal complex peptide conjugates by solid-phase synthesis methods. Procedures for such conjugates are in many cases different from standard solid-phase peptide synthesis protocols. Specific advantages of general strategies, the synthesis of peptide–ligand conjugates and complexation with excess metal ions on solid support or the incorporation of previously prepared metal complex amino acid derivatives are discussed.
Insertional Achilles tendinopathy in patients with Haglund's syndrome: results of computer modeling and biomechanical research

In this study, a biomechanical relationship was found between the pathological process in Haglund syndrome and secondary tendinopathy of the Achilles tendon. We have developed the calculation diagram, created computer models and determined the values of the stress-strain state of the rear foot structures in the normal and with Haglund syndrome. It was found that the maximum stress values are concentrated on the Achilles tendon, but in pathological model the stress values were significantly higher than normal in the whole range of motion of the foot. Normally, maximal stress on the calcaneus is localized on its posterior surface - on the anterior surface of the retrocalcaneal recess. In Haglund syndrome, maximum stress was recorded on the upper surface of the posterior sections of the calcaneus. Haglund syndrome is marked by overloading of the calf muscle. The results of this study explain the development of degenerative changes in the AT in patients with Haglund syndrome. It was also found that the enlarged posterior-upper part of the calcaneus is a factor in the development of insertional Achilles tendinopathy, which should also be considered when choosing further treatment.
Psycho-demographic Factors Influencing Social Well-being among Mobile Police Force

Introduction: There is overwhelming evidence in the increase of dysfunctional social well-being among service members returning from deployment, and this is culminating into a wide range of social challenges. The present study investigated the psycho-demographic factors influencing social well-being among mobile police force in Kwara State, Nigeria. Method: The study adopted a survey method utilizing an ex-post-facto design. The purposive sampling technique was used to sample 200 mobile police officers (152 males and 48 females). They completed a questionnaire pack which included-the Post-Deployment Readjustment Inventory Scale, Emotion Regulation Questionnaire and Mental Health Continuum of Social Well-being-Short Form. Data were analyzed using descriptive statistics, Pearson Product Moment Correlation, ANOVA and Multiple Regression. Results: Findings showed that emotion regulation has a positive relationship with social well-being. Also, age, emotion regulations and post-deployment stress as a whole significantly predicted social well-being among the sampled participants. However, emotion regulation independently predicted social well-being, though marital status did not significantly influence social well-being among the participants. Conclusion: This study presented emotion regulation as a great predictor of social well-being. It is recommended that; emotion regulation should be built into the training and debriefing of mobile police before and after deployment to aid their better social well-being.
Adsorption Study of Heavy Metals Removal from Wastewater Using PVA- Nano Ferrite Composites

The aim of the present investigation is to synthesize Barium ferrite and Nickel ferrite Nanoparticles by co-precipitation method and these nanoparticles are used to prepare nanocomposites with poly vinyl alcohol (PVA). The composited nanoparticles are characterized by using FTIR, XRD and SEM. The synthesized nanoparticles are used as adsorbent to remove the heavy metals such as Cu2+, Cd2+, Pb2+ from simulated industrial waste water. The experimental parameters such as contact time, adsorbent dosage and pH have been studied on the percentage removal of metal ions. It is observed from the experiment, that 100% and 99.05% of Cu2+ has been removed by PVA-Barium and PVA-Nickel ferrite nanocomposites respectively. The experimental data were analyzed using the Langmuir and Freundlich isotherm. The synthesized nanoparticles have greater potential for adsorption of heavy metal ions present in simulated industrial wastewater. These nanoparticles with polymeric composites can be effectively used as adsorbents in the commercial scale to achieve the desired goal of clean environment.
Updated X-ray view of the Hyades cluster

Aims. We revisit the X-ray properties of the main sequence Hyades members and the relation between X-ray emission and stellar rotation. Methods. As an input catalog for Hyades members, we combined three recent Hyades membership lists derived from Gaia DR2 data that include the Hyades core and its tidal tails. We searched for X-ray detections of the main sequence Hyades members in the ROSAT all-sky survey, and pointings from ROSAT, the Chandra X-Ray Observatory, and XMM-Newton. Furthermore, we adopted rotation periods derived from Kepler’s K2 mission and other resources. Results. We find an X-ray detection for 281 of 1066 bona fide main sequence Hyades members and provide statistical upper limits for the undetected sources. The majority of the X-ray detected stars are located in the Hyades core because of its generally smaller distance to the Sun. F- and G-type stars have the highest detection fraction (72%), while K- and M-type dwarfs have lower detection rates (22%). The X-ray luminosities of the detected members range from ∼2 × 1027 erg s−1 for late M-type dwarfs to ∼2 × 1030 erg s−1 for active binaries. The X-ray luminosity distribution functions formally differ for the members in the core and tidal tails, which is likely caused by a larger fraction of field stars in our Hyades tails sample. Compared to previous studies, our sample is slightly fainter in X-rays due to differences in the Hyades membership list used; furthermore, we extend the X-ray luminosity distribution to fainter luminosities. The X-ray activity of F- and G-type stars is well defined at FX/Fbol ≈ 10−5. The fractional X-ray luminosity and its spread increases to later spectral types reaching the saturation limit (FX/Fbol ≈ 10−3) for members later than spectral type M3. Confirming previous results, the X-ray flux varies by less than a factor of three between epochs for the 104 Hyades members with multiple epoch data, significantly less than expected from solar-like activity cycles. Rotation periods are found for 204 Hyades members, with about half of them being detected in X-rays. The activity-rotation relation derived for the coeval Hyades members has properties very similar to those obtained by other authors investigating stars of different ages.
The Van der Waals interaction between metals

The nonretarded Van der Waals energy, EVdW, between two metal slabs is calculated using the random phase approximation and an infinite potential barrier at each surface. It is shown that EVdW comes from the change in surface plasmon zero point energy, and making use of this, asymptotic results are obtained which show when the Lifschitz results (1956) become valid. With an electron density corresponding to Al, EVdW at the smallest separation compatible with the infinite barrier model is -260 erg cm-2, much less than the Lifschitz value and 1/10 of the surface exchange-correlation energy. However, by a separation of 10 au, EVdW is within 10% of the Lifschitz result.
