Journal's Impact Factor Records
Our Impact Factor (IF) is calculated according to the standard formula published by Clarivate Analytics (previously ISI). Below is an example for calculation of 2016 IF.

A = 6 citations (number of times articles published in 2014 and 2015, cited in 2016).
B = 20 articles (total number of articles published in 2014 and 2015).
A/B = 0.300 (IF for 2016).

IF for subsequent years were calculated using similar method and the value is announced in July of the relevant year. The journal was started in 2014.

NOTE: Raw data used in this calculation can be accessed from the journal’s citation records by Google Scholar

IF for 2018
A = 64 citations
B = 141 articles
IF for 2017 = 0.454
H-Index = 6
= 1
IF for 2017
A = 36 citations
B = 90 articles
IF for 2017 = 0.400
H-Index = 4
= 0
IF for 2016
A = 6 citations
B = 20 articles
IF for 2016 = 0.300
H-Index = 2
= 0

Preliminary Investigation on the Effect of Centrifugal Force on Germination and Early Growth of Maize (Zea mays L.)
Barka Mshelmbula; Gbenga Akomolafe. 2019. Transactions on Science and Technology, 6(4), 328 - 333
Abstract This study aimed to investigate the effect of centrifugal force on the growth of maize, an important cereal crop in Nigeria. The maize seeds were subjected to centrifugation for three revolutions (1000g, 5000g, and 10000g) for 2, 4 and 6 hours. The seeds were planted and observed for germination and early growth for seven days. Results revealed that seeds treated with 1000g centrifugal force for 4hrs had the highest germination percentage (70%), while 50% of the control seeds germinated at the end of the 7th day. The radicle length in the 10,000g/2hrs treatment was also the highest (24 cm). However, the highest shoot length was observed in the control plants. This showed that though centrifugal force triggered a rapid and higher germination rate in the treated maize plants, it still did not result in higher shoot length in those plants. The experiment should be extended until the yield or maturity stage in order to have more profound observation on this centrifugal force effect on the maize plants. View article

Electronic Nose Detection of Ganoderma boninense Volatile Organic Compounds (VOCs) Using Direct Headspace Analysis

Abstract Electronic nose detection techniques have found wide applications in many fields including the medical and health sector, food industry, and also agriculture. Detection of volatile organic compounds (VOCs) emitted by Ganoderma boninense is increasingly explored as a reliable means of accurately diagnosing the presence of this important oil palm pathogen, facilitating management of the disease and preventing further spread in the field. For this purpose, we tested an electronic nose (‘zNOSETM 4200’) to detect G. boninense VOCs via direct headspace analysis from samples of trunk cores and inoculated oil palm ramets. We successfully identified five VOC markers (two for healthy tissue, three associated with G. boninense infection). Based on gas chromatography-mass spectrometry (GC-MS) of samples and analytical standards, one of the VOC markers for G. boninense-infected palms was positively identified as 2, 4-di-tert-butylphenol. These markers can be used in the next stage of optimization and field testing. View article

Relationship Between Debris Flow and Precipitation From Nantou and Chiayi County in Taiwan
Chun-Yu Lin; Kuei-Hsiang Cheng. 2019. Transactions on Science and Technology, 6(4), 340 - 351
Abstract This study collected data on debris flow and precipitation from Nantou and Chiayi districts in Taiwan. According to past reports of debris flow by the Bureau of Water Conservation, there have been 19 debris flow in the Nantou area and 14 debris flow in the Chiayi area for a total of 33 reports of debris flow. Among them, 8 (42%) of the Nantou debris flow were classified potential debris flow torrents, and 11 were ordinary unclassified torrents. There were 8 events of potential debris flow torrents (57%) in the Chiayi area, and 6 ordinary unnamed torrents. According to the hydrological data from the disaster report, precipitation patterns were analyzed using effective accumulated precipitation (R), the duration of sustained precipitation, the duration of alert level precipitation, and the precipitation intensity (I) during debris flow. The precipitation patterns were analyzed using level 1 and level 2 graphs, and findings showed that there are 6 different types of precipitation patterns during debris flow. The results showed that the most significant precipitation patterns were: level 1 short-duration heavy precipitation and level 2 short-duration heavy precipitation, as short duration heavy precipitation occurred 17 times and accounted for 52%. This is in line with the current extreme climate, as short-duration torrential rain can cause disasters. The lesser-occurring mild precipitation is divided into two types: level 1 long-duration mild precipitation and level 2 short-duration long-duration mild precipitations. They occurred 2 times and accounted for 6%. A disaster prevention mechanism should be established in the future to prevent the occurrence of debris flow caused by heavy precipitation. View article
