Contemporary tobacco-related studies are mostly concerned with a single social media platform while missing out on a broader audience. Moreover, they are heavily reliant on labeled datasets, which are expensive to make. In this work, we explore senti
ment and product identification on tobacco-related text from two social media platforms. We release SentiSmoke-Twitter and SentiSmoke-Reddit datasets, along with a comprehensive annotation schema for identifying tobacco products' sentiment. We then perform benchmarking text classification experiments using state-of-the-art models, including BERT, RoBERTa, and DistilBERT. Our experiments show F1 scores as high as 0.72 for sentiment identification in the Twitter dataset, 0.46 for sentiment identification, and 0.57 for product identification using semi-supervised learning for Reddit.
This study investigated the effect of the water extract of two types
of algae which spread in Syrian marine: Colpomenia sinuosa
(Brown) and Ulva fasciata (green) and a combination of them in
the cultivation on tomato and tobacco seeds with concent
rations of
(1: 2 1: 4 1: 6 1: 8 1:10 1: 20) By adding 5ml of each
concentration, and comparing it with the control sample with only
distilled water added, the comparison was made in terms of: The
germination, stem length, root length, root branch.
The effect of clay soil treatment with two levels of tobacco west compost and
organic fertilizer (15 and 30 ton/ h), in addition to mineral fertilizer treatment, with three
replicates of each treatment on some physical properties (Aggregate size di
stribution, main
weight diameter, bulk density and porosity) and chemical properties (Organic carbon,
humic and volvic acid and humification index for big and small soil aggregates was
studied.
The results showed that tobacco west compost and organic fertilizer were effective in
increment of soil content of organic carbon, which reached (20 and 26%) for organic
fertilizer, and (39 and 45%) for compost compared to the control, conducing to ameliorate
soil physical properties, where The main weight diameter, stable aggregate rate and soil
porosity were increased. Whereas, bulk density decreased significantly in both treatments
compared to the control. Compost treatment affect soil physical properties more than
organic fertilizer.Mineral fertilizer decreased soil content of organic carbon compared to
the control.
Humic and volvic acids contents were between 2.12 and 74.3 mg/kg aggregates in
the control,and compost treatments alternatively in macro aggregates (> 2mm). Wile,
volvic acid values were between 0.93 mg/kg in control for small aggregates (< 0.25), and
3.17 mg/kg aggregates in mineral fertilizer treatment for (0.25 – 2) aggregates.
Humification index values were less than 2 in macro aggregates, while it was bigger than 2
in small aggregates.
Given the economic importance of tobacco in the Syrian coast, which is one of the most important agricultural crops which contribute to raising the level of economic life.
In this research we focused on studying the varieties of tobacco produced in
the Syrian coast by studying the quantities produced of each item and the costs and revenues of the production and profitability of production and its role in agricultural GDP during the period (2000-2011), which gives a clear picture of the impact on economic development, through applying multiple regression to examining the contribution of various tobacco varieties produced on the Syrian coast agricultural GDP, and is based on data collected from the General Organization for tobacco and cigarettes company in the governorate of Latakia. One of the most important findings:
1. Type Verginia achieved higher profitability during the period (2000-2011), while the lowest type Zegreen profit achieved during the same period.
2. - Shak Elbent followed by Verginia and Tanbak are considered the most important types and the most contributable to the Agricultural Domestic Product (ADP).
3- There is no impact of the profitability of Basma and Prilep and Gernata and Zegreen and Berly types produced in the Syrian coast on the Agricultural Domestic Product (ADP).
This research study the improvement of the performance of drying the agriculture products in (solar dryer-greenhouse), therefore; the design of the solar dryer had modified. The thermal storage unit became bigger, and the glass transparent roof cover
ed by thermal isolation sheet to reduce the thermal losses at night, a centurial fan was put on the drying tunnel to increase the speed of drying of Tobacco olives by increasing the hot drying air flue. The solar dryer tested in the tobacco researches center in Ramilah in Lattakia by drying samples of tobacco(Brly, Bassma) during the period of June,2013. The dried products in the solar dryer were completely protected from rains and insects, and the dried products are of high quality, The tobacco(Brly, Bassma) being dried in the dryer in four and three days, respectively.
This study was conducted in Tobacco fields in the Syrian coast to investigate Root-knot Nematode on two varieties of tobacco (Burley and Flue-cured). Two hundred and five samples of the roots of infected plants were collected from 32 fields in the pe
riod between early August and early October. The results showed that the degree of infestation was high (fifth degree) to Flue-cured tobacco (average was 179.20 knot for one sample), and fourth degree to the Burley tobacco (average 39.95 knot on one sample).
There were three species of Meloidogyne: M.javanica, it had the most frequency 46.25 % and 43.7 % of Burley and Flue-cured tobacco respectively, followed by M.incognita 26.25 % and 24.44% of samples respectively. These species were present together in less frequency on both studied varieties. Whereas the third specie M.arenaria only appeared in three sites of Flue-cured tobacco in less frequency (5.18 %) and was associated with M.incognita.
