A number of more recent discoveries in microbiology have made reliable identification of nano-biomolecules and extensive analyses of them necessary. A variety of proteins, including DNA, biotin-streptavidin, amino acids, as well as many types of bacteria and viruses, must be found and analyzed in order to fully comprehend any odd behavior occurring inside of live cells. Rapid testing and detection are essential steps in preventing undiscovered biohazards from eradicating the human race and other terrestrial living things. Since many decades ago, developing an accurate, affordable biosensor has been a struggle for scientists [1]. When compared to pricey laboratory-based sensors and detection methods, FET-based lab-on-chip nano biosensors appear to be a promising substitute. It is significantly more dependable than conventional bulk sensors because of its size, affordability, low power consumption, resilience, faster response time, and better sensitivity [1]. Due to their precision, adaptability, and compatibility with embedded systems, dielectrically modulated FET biosensors with Nano cavities are emerging as a promising research area that can yield useful data on bio-analyses. As an alternative to conventionally doped TFET devices, using a charge plasma SiGe-heterojunction double gate TFET, a label-free biosensor can be produced, bypassing the need for conventional semiconductors, which require a large thermal budget and are susceptible to random dopant fluctuations (RDFs). The effect of changing the dielectric constant (k), the positive and negative charge density, the gate work function, and the cavity size has been investigated to better understand how these factors affect the performance of the proposed biosensor. These parameters modify the biosensor's electric characteristics, improving detection [2]. There is also discussion of how these factors influence the device's drain current, electric field, surface potential, sub-threshold swing (SS), insulator-to-metal film (ION/IOFF) ratio, and electron tunneling rate (ETR). The sensitivity of the drain current in the proposed biosensor is also investigated. There is no restriction on whether or whether the proposed structure is used for charged or neutral molecules.Under lower supply voltages, it is discovered that the SG-DM current JLFET's sensitivity is high, measuring 1.2 *10^3, with a potential sensitivity of 1.4 V. A result, the SG-DM [2] JLFET exhibits good application potential while consuming little power and having ahigh sensitivity.

Mathematics as a subject need to be learned comprehensively. Yet, the complexities of problem-solving cause difficulty and anxiety among students. With these, mathematics should be made easy to understand by giving more emphasis on teaching strategies to be used like the Perpend, Pair, and Partake (3Ps) a less lecture, more learner -centered and directed learning, and a much more relaxing way of instructional approach in teaching. This quantitative experimental research investigated the significant differences in achievement scores of the Grade 9 students of Abra State Institute of Sciences and Technology - Bangued Campus before and after the use of the 3Ps Strategy. The researcher utilized researcher-made test questionnaires (validity index = 4.67; KR20 reliability index = 0.90) to determine the achievement scores and t-Test for significant differences set at a 0.05 level of significance. Investigated data exposed a Fair level of achievement of both groups (Control and Experimental) before the use and revealed an excellent level of achievement in the experimental group after the use of the strategy (t-Stat = 4.137; t-prob = 0.000). The level of achievement of the student respondents after the use of the 3Ps strategy significantly improved, thus Perpend, Pair, and Partake (3Ps) Strategy is an effective strategy in improving the students’ mathematics achievement.

  • Sanjay Singh, Garima Garg, Vinita Singh, Kapil Dave

In this paper, an inventory model has been developed with ramp type demand and time-dependent holding cost. At the beginning of the cycle, the holding cost increases linearly with time and then becomes constant. The effect of deterioration has been taken into account and considered as a linearly increasing function of time. The main objective of the proposed paper is to derive the inventory policies for minimizing the total cost involved in developing inventory model. The convexity of the total cost has been shown graphically. Also, a numerical example has been solved to illustrate and validate the model.

A Comparative Study of Energy Consumption, Global Warming Potential and Impact Categories of Four Different Blends of Concrete Using Cradle to Gate Life Cycle Assessment
  • Aug 19, 2022
  • Mathematical Statistician and Engineering Applications
  • Trupti Parmar, Siddharth Shah

The present study is a comparison of four different concrete mixes using ‘cradle to gate’ life cycle assessment. The aim is to obtain environmental impact, focusing mainly on criteria pollutants (CO, lead (Pb), PM10, NOx, SO2, and volatile organic compounds), global warming potential, energy consumption, and impact categories like human health, ecosystem quality, and resources. Each concrete mix design has different binder combination. CONOPC contains ordinary Portland cement (OPC) as a binder. CONPPC has 27% Fly ash + 73% OPC while CON PSC has 47% ground granulated blast furnace slag (GGBS) + 53% OPC as a binder. CONGP has 100% fly ash as a binder without the use of cement. The comparative results show that all three concrete mixes, i.e., CONPPC, CONPSC, and CONGP, performed better than CONOPC in terms of harmful gas emissions, energy use, and GWP. Further, with respect to three impact categories, CONOPC has the highest score with 11.06 pt and CONGP has the lowest score with 1.68 pt. CONPPC shows a reduction by almost 30% with a value of 7.77 pt whilst CONPSC shows an even further reduction by 46% with a value of 5.95 pt compared to CONOPC. It is recommended that OPC cement should be replaced by either Portland slag cement (PSC) or Portland pozzolana cement (PPC) in concrete production. Geopolymer concrete is also a good substitute for traditional concrete. Recommendations from this work would assist concrete producers to choose the best available options without compromising the performance of concrete while reducing the negative environmental impact during production.
