前 試驗에 이어 SM混用區의 GA_3 濃度를 50ppm으로 높이고 處理時期의 폭을 滿開前 18, 16, 14, 12, 10일로 하여 GA_3 單用區의 대체여부를 試驗한 結果는 다음과 같다. 1. 滿開期는 兩主區 모두 無處理보다 2~3일 빨랐다. 2. 熟期는 兩主區 모두 無處理보다 25일 정도 早熟되었고 單用區가 混用區에 비하여 1~2일 早熟되었으며 各細區間에 處理時期가 빠를수록 1~2일 정도 早熟되는 경향이 있었다. 3. 無核化率은 混用區는 40개區 모두 有核粒이 없었고, 單用區는 40개區 中 19개區에서 1~6개의 有核粒이 나타났다. 4. 收穫果房狀態는 單用區가 混用區에 比해서 1%水準 以上의 有意差로, 果房長은 길고 5%水準 以上의 有意差로, 平均 果粒重은 무거웠다. The studies were conducted continuously following previous test to determine the possibility of utilization with streptomycin for seedless berries production in Delaware grapes. The main plots which were applied with different chemicals(combind solution of GA_2(50ppm)+SM(200ppm), GA_3(100ppm) alone solution) as pre-bloom application and five split plots according to days applied before full bloom were designed. The results obtained were as follows; 1. The days of full bloom in both main plots was accelerated by two to three days compared with that in the untreatment. 2. The day of maturity showed tendency to delay one to two days in combined solution plot compared with that in alone solution plot. 3. In all combined solution plots, seed-holding berry was not found, but, in alone solution plots, they were found in nineteen out of forty plots. 4. The length of cluster harvested in combined solution plot was short and mean weight of berry was light compared with that in alone solution plot

Sani, Rabiya,Manivannan, R.,Victoria, S. Noyel The Korean Electrochemical Society 2018 Journal of electrochemical science and technology Vol.9 No.4

Single step electrodeposition of $Cu_2ZnSnS_4$ (CZTS) for solar cell applications was studied using an aqueous thiocyanate based electrolyte. The sodium thiocyanate complexing agent was found to decrease the difference in the deposition potential of the elements. X-ray diffraction analysis of the samples indicates the formation of kesterite phase CZTS. UV-vis studies reveal the band gap of the deposits to be in the range of 1.2 - 1.5 eV. The thickness of the deposit was found to decrease with increase in pH of the electrolyte. Nearly stoichiometric composition was obtained for CZTS films coated at pH 2 and 2.5. I-V characterization of the film with indium tin oxide (ITO) substrate in the presence and the absence of light source indicate that the resistance decrease significantly in the presence of light indicating suitability of the deposits for solar cell applications. Results of electrochemical impedance spectroscopic studies reveal that the cathodic process for sulfur reduction is the slowest among all the elements.

Analytical Evaluation of FFR-aided Heterogeneous Cellular Networks with Optimal Double Threshold

( Sani Umar Abdullahi ),( Jian Liu ),( Seyed Alireza Mohadeskasaei ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.7

Next Generation Beyond 4G/5G systems will rely on the deployment of small cells over conventional macrocells for achieving high spectral efficiency and improved coverage performance, especially for indoor and hotspot environments. In such heterogeneous networks, the expected performance gains can only be derived with the use of efficient interference coordination schemes, such as Fractional Frequency Reuse (FFR), which is very attractive for its simplicity and effectiveness. In this work, femtocells are deployed according to a spatial Poisson Point Process (PPP) over hexagonally shaped, 6-sector macro base stations (MeNBs) in an uncoordinated manner, operating in hybrid mode. A newly introduced intermediary region prevents cross-tier, cross-boundary interference and improves user equipment (UE) performance at the boundary of cell center and cell edge. With tools of stochastic geometry, an analytical framework for the signal-to-interference-plus-noise-ratio (SINR) distribution is developed to evaluate the performance of all UEs in different spatial locations, with consideration to both co-tier and cross-tier interference. Using the SINR distribution framework, average network throughput per tier is derived together with a newly proposed harmonic mean, which ensures fairness in resource allocation amongst all UEs. Finally, the FFR network parameters are optimized for maximizing average network throughput, and the harmonic mean using a fair resource assignment constraint. Numerical results verify the proposed analytical framework, and provide insights into design trade-offs between maximizing throughput and user fairness by appropriately adjusting the spatial partitioning thresholds, the spectrum allocation factor, and the femtocell density.

Arabic Gum Grafted PEGDMA Hydrogels: Synthesis, Physico-Chemical Characterization and In-vitro Release of Hydrophobic Drug

Sani Mamman Ibrahim,Teo Yin Yin,Misni Misran 한국고분자학회 2020 Macromolecular Research Vol.28 No.13

Hydrogel development using natural and synthetic polymers for biomedical applications have shown promising properties for drug delivery due to virtuous stimuli response and improvement in mechanical strength. Biomaterial hydrogel was synthesized using combination of arabic gum (AG), a natural polymer and polyethylene glycol dimethacrylate (PEGDMA), a synthetic polymer. The synthesis process follows chemical cross linking by free radical polymerization. Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM) and differential scanning calorimetry (DSC) were used to characterize the hydrogels. Product yield, gel content and gelation time depends solely on the variable reacting concentrations and the mechanical properties of hydrogel depends on its compositions. Swelling studies reveal high swelling ratio in buffer solution pH 1.2 compare to buffer solution pH 7.4, and deionized water at pH 6.7. Swelling ratio raises with increase in PEGDMA concentration, but the presences of salt/ions solutions decreases the swelling ratio significantly and it depends on the charge of the ions. The kinetics of the swelling follows a second order non-linear rate equation. The rate of degradation revealed significant degradation in acidic medium and insignificant degradation was observed in basic medium. The encapsulation efficiency of quercetin introduced directly in the hydrogels during synthesis was found in the range of 85-94%. The release profile indicates the dependence of arabic gum grafted PEGDMA hydrogels on pH and compositions. The characteristic properties exhibited by the formulated hydrogels suggest the suitability of them to be applied as drug carriers.

Many nations are already working toward full implementation of energy efficiency in buildings known as Green Building. In line with this perspective, this paper aims to develop a thermally efficient precast concrete sandwich panels (PCSP) for structural applications. Therefore, an experimental investigation was carried out to determine the thermal resistance of the proposed PCSP using Hotbox method and the results were validated using finite element method (FEM) in COMSOL Multiphysics Software. The PCSP were designed with staggered shear connectors to avoid thermal bridges between the successive layers. The staggered connectors are spaced at 200 mm, 300 mm and 400 mm on each concrete layer, while the control panel is designed with 200 mm direct shear connection. In the experimental test, four (4) panels of 500 mm × 500 mm and 150 mm thick were subjected to Hotbox Test to determine the thermal resistance. The result shows that thermal resistance of the PCSP with staggered shear connection increases with increase in spacing. The PCSP with 400 mm staggered shear connectors indicates the best thermal efficiency with a thermal resistance (R value) of 2.48 m²K/W. The thermal performance was verified by FEA which shows less than 5% error coupled with a precise prediction of surface temperature gradient. This indicates that, with conventional materials, thermal path approach can be used to develop a precast concrete building with better thermal resistant properties. Hopefully, stakeholders in the green building industry would find this proposed PCSP as an alternative energy efficient load bearing panel towards sustainable and greener buildings.

Achmad Sani SUPRIYANTO,Agus Eko SUJIANTO,Vivin Maharani EKOWATI 한국유통과학회 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.11

This study aimed to investigate the influence of spiritual leadership on innovative work behavior and the effect of knowledge sharing on job crafting. Furthermore, the roles of knowledge sharing as a mediator for the impact of spiritual leadership on innovative work behavior, and job crafting as a mediator for the relationship between variables, were also examined. This research employed quantitative analysis, including the PLS-SEM approach; SMART-PLS, a measurement and structural equation model was employed to explain the relationship between variables, and the effect of mediation. The population study consisted of all lecturers at the Faculty of Economics and Faculty of Economics and Business at the PTKIN in East Java, Indonesia, comprising 220 randomly-selected samples. The result showed spiritual leadership does not directly influence innovative work behavior, while knowledge sharing directly affects job crafting. The findings indicated knowledge sharing mediates the impact of spiritual leadership on innovative work behavior, and the role of job crafting as a mediator for the relationship between variables was accepted. Therefore, this research confirms a positive influence of knowledge sharing on job crafting, and indicates both factors play an important role in mediating between variables, and are important for lecturers’ innovative work behavior.

The treatment of premenstrual dysphoric disorder (PMDD) is far from satisfactory, as there is a high proportion of patients who do notrespond to conventional treatment. The antidiuretic sulfonamide, acetazolamide, inhibits carbonic anhydrase and potentiates GABAergictransmission; the latter is putatively involved in PMDD. We therefore tried acetazolamide in a series of women with intractable PMDD. Here, we describe a series of eight women diagnosed with DSM-IV-TR PMDD, five of whom had comorbidity with a mood disorder andone with an anxiety disorder, who were resistant to treatment and responded with symptom disappearance after being added-on 125mg/day acetazolamide for 7-10 days prior to menses each month. Patients were free from premenstrual symptoms at the 12-month follow-up. We suggest that acetazolamide may be used to improve symptoms of PMDD in cases not responding to other treatments. GABAergicmechanisms may be involved in counteracting PMDD symptoms.

Hydrogenation effects on the thermal and magnetic properties of mono- and bilayer graphene

Sohrabi Sani Shahdokht,Mousavi Hamze,Jalilvand Samira,Asshabi Moein 한국탄소학회 2021 Carbon Letters Vol.31 No.5

In the present study, the nearest-neighbor tight-binding model has been employed to calculate the density of states (DOS), electronic heat capacity (EHC), and Pauli magnetic susceptibility (PMS) of hydrogenated systems, namely monolayer graphone and graphane, bilayer graphone–graphene, and bilayer graphane–graphene. Then, the results have been compared with that of monolayer and simple bilayer graphene. It was found that the behaviors of hydrogenated systems difer from those of monolayer and bilayer graphene near the Fermi Level. Also, monolayer graphone and bilayer graphone–graphene exhibit a high peak near the Fermi level. Graphane monolayer, on the other hand, has no states around the Fermi level. Furthermore, bilayer graphane–graphone, similar to graphene, is a semimetal. Also, Schottky anomaly peaks in the EHC curves and crossovers in the PMS curves can be observed, which have divided the domain into two regions of low and high temperature. Compared to hydrogenated systems, the Schottky anomaly in graphene monolayer and bilayer graphene occurred at lower temperatures, while the PMS of monolayer graphone and bilayer graphone–graphene were faster than other systems in reaching the crossover. From the theoretical standpoint, these phenomena are due to the proportional relation of the PMS and EHC with the DOS.
