Fractional integro-differential equations with nonlocal conditions and ψ–Hilfer fractional derivative

Considering a fractional integro-differential equation with nonlocal conditions involving a general form of Hilfer fractional derivative with respect to another function. We show that weighted Cauchy-type problem is equivalent to a Volterra integral equation, we also prove the existence, uniqueness of solutions and Ulam-Hyers stability of this problem by employing a variety of tools of fractional calculus including Banach fixed point theorem and Krasnoselskii's fixed point theorem. An example is provided to illustrate our main results

Assessment of early outcomes of surgical treatment of comminuted fracture calcaneus through trans calcaneal approach

Background: Treatment options for displaced intra-articular calcaneal fractures are still up for debate. The gold standard treatment for intra-articular calcaneal fractures is the conventional extensile lateral approach (ELA). Objective: achievement of good reduction with stable support for intra-articular calcaneal fractures by using trans calcaneal approach aiming for better functional outcome. Methods :On the basis of a prospective cohort research, at Zagazig University Hospital Orthopedic Department we recruited 18 patients with comminuted fractures in the calcaneus who had been admitted to the hospital with intra-articular fractures, Extensive lateral approach and T-plate fixation were used to treat this condition 3 and 6 months after surgery, the American Orthopedic Foot And Ankle Society's functional assessment was performed. Results: All patients eventually achieved full union by the end of follow-up. Only one patient had delayed union. Most of patients (55.56%) had good outcome according to AOFAS score. 11.11% had excellent outcome. While about one third of patients had unsatisfactory outcome, either fair (27.77%) or poor (5.56) AOFAS score. In regard to complications, most of the studied group (61.11%) didn’t have any complications, three patients had surgical site infection, and 11.11% of patients had sural neuritis. Conclusion: The trans-calcaneal method of reduction through ELA is an excellent method for treatment of displaced intra-articular calcaneal fractures, as it provides good exposure and facilitates anatomical reduction of fracture

CALL in Post-Method Era

oai:ojs.indonesian-efl-journal.org:article/33This paper touches on the influx of technology in language learning and teaching with a focus on the post-method era. Scrutinizing this phenomenon within the framework of Computer-Assisted Language Learning (CALL) shows how technology has stimulated a transformation of language pedagogy from the traditional teacher-centered and text-bound classrooms to student-centered and interactive paradigms. While the former paradigm is based on methodology, the latter is guided by principled eclecticism in which teachers make use of a set of macro-strategies so as to make decisions while teaching, instead of reliance on methods that dictate ‘how to teach’. The teaching principles capitalize on teachers’ sensitivity to local contexts rather than general methods. Though CALL has been mooted as panacea for ELT flaws in the method and post-method eras, it is not a one-size-fits-all model. Due to changeable and diversified technological innovations, it is impractical to adopt an electronic device or application for all contexts. Accordingly, the post-method pedagogy puts the onus on language teachers to make informed choices that best fit the particularity of their teaching situations.

Temperature Variation Operation of Mixed-VT 3T GC-eDRAM for Low Power Applications in 2Kbit Memory Array

Embedded memories were once utilized to transfer information between the CPU and the main memory. The cache storage in most traditional computers was static-random-access-memory (SRAM). Other memory technologies, such as embedded dynamic random-access memory (eDRAM) and spin-transfer-torque random-access memory (STT-RAM), have also been used to store cache data. The SRAM, on the other hand, has a low density and severe leakage issues, and the STT-RAM has high latency and energy consumption when writing. The gain-cell eDRAM (GC-eDRAM), which has a higher density, lower leakage, logic compatibility, and is appropriate for two-port operations, is an attractive option. To speed up data retrieval from the main memory, future processors will require larger and faster-embedded memories. Area overhead, power overhead, and speed performance are all issues with the existing architecture. A unique mixed-V_T 3T GC-eDRAM architecture is suggested in this paper to improve data retention times (DRT) and performance for better energy efficiency in embedded memories. The GC-eDRAM is simulated using a standard complementary-metal-oxide-semiconductor (CMOS) with a 130nm technology node transistor. The performance of a 2kbit mixed-V_T 3T GC-eDRAM array were evaluated through corner process simulations. Each memory block is designed and simulated using Mentor Graphics Software. The array, which is based on the suggested bit-cell, has been successfully operated at 400Mhz under a 1V supply and takes up almost 60-75% less space than 6T SRAM using the same technology. When compared to the existing 6T and 4T ULP SRAMs (others' work), the retention power of the proposed GC-eDRAM is around 80-90% lower

Securing voluntary, nonpaid blood donation is an important national goal to prevent blood shortages. The donated blood plays a big role during surgery, accidents, delivery, bleeding cases, and the like. Currently, in many developing and developed countries, the blood supply is critically insufficient. Hence, the aim of this study was to assess the practice of blood donation and associated factors among employees (clinical and nonclinical) at Negele Arsi General Hospital and Medical College.Methods: A facility-based cross-sectional study was conducted from August 1 to 20, 2020. Self-administered and interview-administered questionnaires were used to collect the data. A stratified sampling method was employed to select 122 participants. Data were entered into EpiData 3.1 software and the analysis was done using SPSS version 25. Bivariable and multivariable binary logistic regression analysis with 95%CI was carried out.Results: Among 122 employees who participated in the study, 39% have ever donated blood. Clinical staff were eight times more likely to donate blood compared to nonclinical staff (AOR=7.81, 95%CI: 2.15– 28.39). Those who had one to five years work experience were 85% (AOR=0.15, 95% CI:0.03-0.74) less likely to donate blood compared to > 11 years of work experience.Those with inadequate knowledge were 71.0% (AOR=0.29, 95%CI: 0.09– 0.89) less likely to donate blood compared to those with adequate knowledge. Those with an unfavorable attitude were 68.0% (AOR=0.32, 95%CI: 0.11– 0.92) less likely to donate blood compared to those with a favorable attitude.Conclusion: Generally, blood donation practice was low in the study area. The professional category, work experience, knowledge, and attitude were significantly associated with the practice of blood donation. Therefore, a blood donation campaign should be prepared to strengthen the practice.Keywords: blood donation, practice, associated factors, employees, hospital, Negele Ars

A 2 Kbit memory array of mixed-VT GC-eDRAM implemented in 130nm standard CMOS technology

The minimization of very large-scale integrated circuits is facing a great challenge as the demands of devices with low power, and high-performance characteristics have intensely increased. Achieving a downscaled embedded memory design with a low leakage power, high stability, and minimized area became harder to achieve with SRAM based memories. A memory structure which is of great interest is the Gain-Cell eDRAM (GC-eDRAM). It has a high density, low leakage, logic compatibility, and suitable for two-port operations. This work presents a novel cell topology of mixed-VT 3T GC-eDRAM to improve the data retention times (DRT) and speed for better energy efficiency in embedded memories. Simulations work is conducted to evaluate the performance of a 2 Kbit mixed-VT 3T GC-eDRAM array layout until corner process simulation. Mentor Graphics Software is used to design and simulate each of the block diagrams in 130nm CMOS process technology. The array demonstrated successful operation at 400Mhz under a 1V supply and is almost 60-75% less in area than 6T SRAM in the same technology. The retention power showed about 80-90% lower power consumption as compared to the existing 6T and 4T ULP SRAMs (others' work)
