Abstract:

Tsau, Yang, Li Guan, and Jian-Young Wu. Initiation of spontaneous epileptiform activity in the neocortical slice. J. Neurophysiol. 80: 978–982, 1998. Cortical local circuitry is important in epileptogenesis. Voltage-sensitive dyes and fast imaging were used to visualize the initiation of spontaneous paroxysmal events in adult rat neocortical slices. Although spontaneous paroxysmal events could start from anywhere in the preparation, optical imaging revealed that all spontaneous events started at a few confined initiation foci and propagated to the whole preparation. Multielectrode recording over hundreds of spontaneous events revealed that often two or three initiation foci coexisted in each preparation ( n = 10). These foci took turns being dominant; the dominant focus initiated the majority of the spontaneous paroxysmal events during that period. The dominant focus and dynamic rearrangement of foci suggest that the initiation of spontaneous epileptiform events involves a local multineuronal process, perhaps with potentiated synapses.

Abstract:

Tujuan penelitian ini adalah untuk menentukan tipologi sektor perikanan di Kabupaten Bandung Barat; menganalisis laju pertumbuhan sektor perikanan dalam lima tahun terakhir (2009-2013) Kabupaten Bandung Barat; dan untuk menganalisis peran perikanan sektor pada pembangunan daerah Kabupaten Bandung Barat. Metode penelitian yang digunakan adalah metode survey dengan menggunakan beberapa teknik analisis, yaitu analisis Klassen Tipologi, analisis (LQ), analisis Localization Index (LI), analisis Spesialization Index (SI) dan Shift Share (SS). Hasil penelitian menunjukkan bahwa potensi terbaik dari komoditas di Kabupaten Bandung Barat adalah ikan patin / Pengasius hypophthalmus (jumlah rata-rata LQ komoditas 1,92). Poin keunggulan daerah dengan menggunakan LQ (rata-rata nilai 1,82), LI (di bawah 0,5), dan SI (0,01 nilai 0,07-0,09 / nilai di bawah 0,5). Titik LQ menunjukkan bahwa sektor perikanan di Kabupaten Bandung Barat adalah sektor basis, tetapi poin lain (LI dan SI) menunjukkan bahwa sektor perikanan bukanlah sektor penggerak pada struktur perekonomian wilayah. Berdasarkan tipologi Klassen dan teknik Shift-Share, sektor perikanan di Kabupaten Bandung Barat merupakan sektor dengan pertumbuhan yang lambat dan kurang kompetitif (pada tipologi klassen berada di kuadran 2).

Abstract:

Pada tahun 2025, diperkirakan kebutuhan baterai Li-ion akan mencapai 400.000 ton. Upaya strategis diperlukan untuk mewujudkan pemakaian baterai Li-ion yang berkelanjutan. Setelah siklus pemakaian baterai Li-ion berakhir, baterai Li-ion akan diproses kembali untuk diambil kandungan logam-logam penting yang terkandung di dalam katoda, terutama litium. Secara umum, proses recycle tersebut dilakukan dengan metode hidrometalurgi yang terdiri atas rangkaian leaching dan presipitasi. Namun demikian, dalam proses pemurnian tersebut dihasilkan air limbah yang mengandung beragam logam dengan konsentrasi yang berbeda. Untuk baterai LFP, logam-logam tersebut berasal dari katoda yang mengandung Li, Na, Si, dan PO4. Proses pelindian dan pencucian serbuk katoda membutuhkan air dalam jumlah yang relatif besar. Pengolahan air limbah hasil proses daur ulang baterai diharapkan dapat secara signifikan meningkatkan efisiensi penggunaan air. Pada eksperimen ini, metode adsorpsi batch dengan ion-exchange resin kation Amberlite HPR1100 Na dan resin anion Dowex Marathon A digunakan untuk menghilangkan ion logam dari air limbah artifisial. Pengambilan sampel air limbah yang diolah diambil pada menit ke-3, 6, 10, 20, 30 dan hari ke-3. Berdasarkan pada hasil removal percentage, diperoleh bahwa pengolahan air limbah artifisial metode adsorpsi dengan menggunakan ion-exchange resin kation Amberlite HPR1100 Na dapat mengurangi kadar ion litium dan natrium sampai 100% pada menit ke-20 dengan variasi dosis adsorben 10 g/100 mL, sedangkan penggunaan ion-exchange resin anion Dowex Marathon A dapat mengurangi kadar ion fosfat sampai 100% pada menit ke-30 dengan dosis adsorben 10 g/100 mL. Dengan adsorpsi isotherm didapat model Langmuir lebih sesuai dengan data eksperimen dengan nilai parameter Qm dan KL untuk ion litium sebesar 1,16 mg/g dan 2,57 mg/g, ion natrium sebesar 74,62 mg/g dan 0,04 mg/gL/mg, dan ion fosfat sebesar 208,33 mg/g dan 0,06 mg/g. Selain itu, studi kinetika menunjukkan bahwa model pseudo second-order memiliki kesesuaian data yang lebih baik daripada pseudo first-order.

Abstract:

Rechargeable post Li-ion batteries based on aluminum (Al) are gaining attention due to high abundance of Al, the high theoretical volumetric capacity, and high safety associated with the low flammability [1,2]. In comparison to Li-ion batteries (LiBs), where the solid-electrolyte interphase (SEI) has been studied for decades, little is known on SEI formation in dependence of the used electrolyte for Al electrodes. In this study, we present the electrochemical performance of Al foils with two different thicknesses (0.025 mm and 0.075 mm), which were used as negative electrode in Al-ion batteries in AlCl3/1-ethyl-3-methylimidazolium chloride [EMIm]Cl electrolyte. Atomic force microscopy (AFM) was used to determine changes in the morphology of Al foils during the charge - discharge process to obtain information on the SEI and its microstructural morphology [3]. Spatially-resolved information on the electrochemical activity of interphase layers on cycled Al foils can be obtained via scanning electrochemical microscopy (SECM), which so far has only be studied at LiBs [4]. First results reveal the correlation between the morphological changes of SEI layer during cycling and its electrochemical behavior depending on the Al foil surface properties, which will be presented and discussed in this contribution. Key words: Al foil, AFM, microstructure, SEI layer, SECM.

Abstract:

A Single-Power Alternating Current (SPAC) instrument was used to measure the low-impedance acupoints around Ho-Ku (LI-4), Yang-Hsi (LI-5), Yang-Ch'ih (TB-4), Yang-Ku (SI-5), T'ai-Yuan (Lu-9), Ta-Lung (EH-7) and Shen-Men (He-7). A four-electrode instrument was used to measure the subcutaneous impedance at these low-impedance acupoints and adjacent control points on 12 healthy people. The mean subcutaneous impedance at the acupoints was 49.8±8.4 Ω, significantly lower than the impedance of 53.5±9.3 Ω for the control points (P<0.005). Of the seven acupoints, five (71%) had significantly lower impedances than the mean impedance for the adjacent control points. Seven of the 14 control points had significantly higher impedances than the adjacent acupoints, with most control points (93%) having higher impedances than adjacent acupoints. In conclusion, subcutaneous impedance is lower at the low-impedance points as measured with the SPAC two-electrode method. One interpretation of these results is that more interstitial fluid lies beneath the low-impedance acupoints.

Abstract:

Obesity is a disease defined by excessive fat storage in the body. It is an energy balance problem; the increase in body fat is caused by an imbalance between energy intake and energy expenditure. This study aimed to determinate the changes in the anthropometric measurements of patients after acupuncture treatment used in obesity treatment. The present study was a cross-sectional study conducted in 2019 in xxx University's GETAT Center). Patients aged between 18–65 years with a BMI > 25 were included in the study. The participants were divided into two groups: Group 1 (acupuncture and diet) and Group 2 (diet only). Exclusion criteria: Pregnant women, breastfeeding patients , susceptible demographics (acute coronary insufficiency, immunodeficiency, severe psychotic disorder, liver and kidney failure), and those who could not give consent were not included in the study. Weight, BMI, and metabolic age values were measured with a Tanita device; the same diagnostic device was used for all patients. Both body and ear acupuncture were performed. In patients with all acupuncture, the yuan points of abnormal meridians were used for pulse diagnosis. ST 24, 25, and 36 (ZuSanLi); GV 20, 21, 5, 5, and LR 3 (Taichong); SP 6 and 9, GB 34, UB 62, HT 7, LU 9, and PC 6 (Nei Guan); and SI 3 and EXT-HN 3 (Yin-Tang) points were dewed. For ear acupuncture, hunger, kidney, larynx, stomach, jerome, and shen-men points were taken. A t-test was applied to pre- and post-acupuncture measurement values. After acupuncture, the waist circumference of the participants decreased significantly (p < 0.005). The BMI of the participants also decreased significantly after acupuncture (p < 0.005). In these studies, LU 6, ST 40, ST 21, K 4, ST 36 and 25, and LI 11 body points were used, while hunger, stomach, and shen-men points were commonly used as ear points.

Abstract:

The most important cathodic process in alkali metal-air (M-O2) batteries is the electrocatalytic oxygen reduction reaction (ORR) typically forming superoxide (MO2), and peroxide (M2O2).1 Cation size in aqueous solvents have been demonstrated to affect the ORR activity due to the cation hydration energy.2 However, within aprotic electrolytes, the reaction mechanisms and the activity of ORR with respect to cation size remains undetermined. Traditionally, electrochemistry has been involved in the analysis of the reaction mechanisms of ORR. Nonetheless, this technique by itself is not suitable to identify intermediaries and products of the redox reactions taking place at the electrochemical interface. The combination of cyclic voltammetry with in situ Raman spectroscopy provide the opportunity to study and develop a fundamental understanding of the ORR under potential control, accessing reaction pathways and relating them directly to surface structure.3 In this sense, the breakthrough of Shell-Isolated Nanoparticles for Enhanced Raman Spectroscopy (SHINERS)4,5 is noteworthy. SHINERS is a non-destructive, powerful technique for surface analysis that has been demonstrated to provide SERS effect even in the absence of intrinsic roughness and without requiring Au, Ag or Cu to be used as working electrodes.3,5 In this work, electrochemical measurements and SHINERS are utilised to study the effect of cation upon electrified interfaces during ORR.
