作者： Jo.é o. Payero Edisto.Research and Educatio. Center Clemson University Blackville SC USA Department o. Agricultural Sciences Clemson University Clemson SC USA

There is co.siderable co.cern abo.t the po.ential impact o. climate change o. agriculture, such as the accumulatio. o. chilling ho.rs needed to.break the do.mancy o. many perennial plants, like fruit trees. Therefo.e, this study aimed to.determine if there had been a significant change in air temperatures and chill ho.rs, chill units, and chill po.tio. accumulatio. in So.th Caro.ina o.er the last two.decades. Two.decades o. daily maximum (Tmax) and minimum (Tmin) air temperature reco.ds were o.tained fro. weather statio.s in thirty-o.e co.nties in So.th Caro.ina. Ho.rly temperature data, reco.structed fro. the daily data, were used to.calculate the daily and annual chill ho.rs, chill units, and chill po.tio.s accumulatio. using fo.r different chill mo.els fo. each lo.atio. and year. The chill mo.els included the T(t) °C mo.el, the 0°C °C mo.el, the Utah mo.el, and the Dynamic mo.el. Fo. each co.nty, regressio. analyses were co.ducted to.evaluate the histo.ical trends. Despite year-to.year variability, the tendency was a statistically significant (α = 0.05) increase in air temperature, averaging 0.089°C per year fo. 20 o.t o. 31 co.nties in So.th Caro.ina. The o.her 11 co.nties had no.significant change in temperature. The average temperature increase in the 31 co.nties was 0.072°C per year. The temperature increase resulted in a decrease in annual chill accumulatio. during the fall to.spring, averaging 17.7 chill ho.rs, 8.6 chill ho.rs, 17.0 chill units, and 0.40 chill po.tio.s per year calculated with the T(t) °C, 0°C °C, Utah, and Dynamic mo.els, respectively. Ho.ever, whether this decrease in chill values was statistically significant o. no. depended o. the chill mo.el used. This study did no. investigate the cause o. the o.served histo.ical trends in temperature and chill accumulatio.. Still, if the trends co.tinue, they co.ld significantly impact the future o. the temperate fruit tree industry in the state.

A Review: Manufacturing, and Pro.erties o. the D-Fructo.e Epimer D-Allulo.e (D-Psico.e)

引用

Advances in Bio.cience and Bio.echno.o.y 2024年第9期15卷 522-542页

作者： o.ama o. Ibrahim Bio.nno.atio. LLC Gurnee IL USA

D-allulo.e, also.kno.n by the name D-psico.e o. just allulo.e, is a rare keto.sugar epimer o. D-fructo.e in the third carbo. (C3), and naturally o.curs in small quantity in fruits such as grapes and figs. It is lo. calo.ie sweetener pro.uced enzymatically fro. D-fructo.e by enzymes D-keto.e 3-epimerase (DKEase) family. D-allulo.e has a similar taste, texture and functio.ality as sweetener co.paring to.high calo.ie sweetener sugar table sucro.e. D-allulo.e is po.rly metabo.ized in the bo.y with minimal impact o. blo.d sugar levels making it a natural lo.-calo.ie sweetener. This pro.erty makes D-allulo.e an attractive sweetener fo. diabetes and fo. bo.y weight management. Labo.ato.y studies o. D-allulo.e intake demo.strated its safety with no.significant adverse effects. United States Fo.d and Drug Administratio. (FDA) has granted D-allulo.e the status o. Generally Reco.nized as Safe (GRAS). Plus, it is co.sidered safe fo. human co.sumptio. by regulato.y o.ganizatio.s in o.her co.ntries except in Euro.ean Unio. due to.their request fo. further labo.ato.y testing. Maximum acceptable daily intake o. D-allulo.e is 0.9 grams per kilo.ram bo.y weight. Excessive intake fo. mo.e than the reco.mended daily intake co.ld lead to.so.e side effects such as gastro.ntestinal disco.fo.t o. laxative effects. In general, D-allulo.e is co.sidered o.e o. the preferred natural lo. calo.ies sweeteners fo. tho.e seeking an alternative to.table sugar sucro.e.

A Pro.edure fo. Trisecting an Acute Angle (Metho. 2)

引用

Advances in Pure Mathematics 2024年第4期14卷 204-213页

作者： Lyndo. o. Barto. Department o. Math and Physics Delaware State University Dover USA

This paper presents an alternate graphical pro.edure (Metho. 2), to.that presented in earlier publicatio.s entitled, “A Pro.edure fo. Trisecting an Acute Angle” and “A Key to.So.ving the Angle Trisectio. Pro.lem”. The pro.edure, when applied to.the 30˚ and 60˚ angles that have been “pro.en” to.be no.trisectable and the 45˚ benchmark angle that is kno.n to.be trisectable, in each case pro.uced a co.structio. having an identical angular relatio.ship with Archimedes’ Co.structio., as in Sectio. 2 o. THEo.Y o. this paper, where the required trisectio. angle was fo.nd to.be o.e-third o. its respective angle (i.e. DE’MA = 1/3 DE’CG). Fo. example, the trisectio. angle fo. the 30˚, 45˚ and 60˚ angles were 10.00000˚, 15.00000˚, and 20.00000˚, respectively, and Sectio. 5 o. PRo.F in this paper. Therefo.e, based o. this identical angular relatio.ship and the numerical results (i.e. to.five decimal places), which represent the highest degree o. accuracy and precisio. attainable by The Geo.eter’s Sketch Pad so.tware, o.e can o.ly co.clude that no. o.ly the geo.etric requirements fo. arriving at an exact trisectio. o. the 30˚ and 60˚ angle (which have been “pro.en” to.be no.-trisectable) have been met, but also. the co.structio. is valid fo. any arbitrary acute angle, despite theo.etical pro.fs to.the co.trary by Wantzel, Dudley, and o.hers.

This study investigates ho. cybersecurity can be enhanced thro.gh clo.d co.puting so.utio.s in the United States. The mo.ive fo. this study is due to.the rampant lo.s o. data, breaches, and unautho.ized access o. internet criminals in the United States. The study ado.ted a survey research design, co.lecting data fro. 890 clo.d pro.essio.als with relevant kno.ledge o. cybersecurity and clo.d co.puting. A machine learning appro.ch was ado.ted, specifically a rando. fo.est classifier, an ensemble, and a decisio. tree mo.el. o.t o. the features in the data, ten impo.tant features were selected using rando. fo.est feature impo.tance, which helps to.achieve the o.jective o. the study. The study’s purpo.e is to.enable o.ganizatio.s to.develo. suitable techniques to.prevent cybercrime using rando. fo.est predictio.s as they relate to.clo.d services in the United States. The effectiveness o. the mo.els used is evaluated by utilizing validatio. matrices that include recall values, accuracy, and precisio., in additio. to.F1 sco.es and co.fusio. matrices.

Climate is subject to.fluctuatio.s in the majo.ity o. the wo.ld, mainly caused by rainfall as well as temperature variatio.s. Climate fluctuatio.s in Kenya have resulted in the spread o. desert-like co.ditio.s in the ASALs regio., such as Marigat in Baringo.Co.nty. As a co.nty, Baringo.experiences great variatio.s in climate annually, as well as uncertainty in expected rains, thereby negatively impacting the pro.uctio. o. cro.s such as so.ghum. This study applied the rainfall ano.aly index (RAI), standardised precipitatio. evapo.ranspiratio. index (SPEI), standard precipitatio. index (SPI), and Mann-Kendall (MK) statistical test fo. trends o. histo.ical climatic data in analysing bo.h temperature and precipitatio. data o.er the perio. 1990 to.2022 to.determine their trend, patterns and ho. they affect the pro.uctio. o. so.ghum cro.s. The machine learning metho. (R studio. with inputs was used to.calculate the SPI, SPEI, RAI and MK trend test. The rainfall varied fro. belo. average to.abo.e average during the study perio. with no.clear pattern in the RAI, SPEI and SPI values. The years 2020 and 2000 sto.d o.t as they had higher and lo.er rainfall than usual, respectively. The Marigat area generally experienced mo.e rainfall during the high/lo.g rainfall seaso. (AMJJ). The MK trend test o. average mo.thly rainfall, So.D, AMJJ, and annual precipitatio. co.firmed a po.itive trend in precipitatio.. Ho.ever, the sho.t rainy seaso. (So.D) was fo.nd to.be the mo.t variable perio. fo. rainfall, and there was a slight increase in daily average temperatures during this seaso..
