N-gram-based machine learning approach for bot or human detection from text messages

Social bots are computer programs created for automating general human activities like the generation of messages. The rise of bots in social network platforms has led to malicious activities such as content pollution like spammers or malware dissemination of misinformation. Most of the researchers focused on detecting bot accounts in social media platforms to avoid the damages done to the opinions of users. In this work, n-gram based approach is proposed for a bot or human detection. The content-based features of character n-grams and word n-grams are used. The character and word n-grams are successfully proved in various authorship analysis tasks to improve accuracy. A huge number of n-grams is identified after applying different pre-processing techniques. The high dimensionality of features is reduced by using a feature selection technique of the Relevant Discrimination Criterion. The text is represented as vectors by using a reduced set of features. Different term weight measures are used in the experiment to compute the weight of n-grams features in the document vector representation. Two classification algorithms, Support Vector Machine, and Random Forest are used to train the model using document vectors. The proposed approach was applied to the dataset provided in PAN 2019 competition bot detection task. The Random Forest classifier obtained the best accuracy of 0.9456 for bot/human detection.

Hematological and histological effect of fractionated neem leaf extract in healthy wistar rats

Introduction: In recent years, the growing research towards new drugs has been targeted on plant-based drugs, and Neem (Azadirachta indica) is one of the plants that have been extensively researched for its diverse medicinal properties. The study aimed to determine the effects of neem on the hematological parameters (total white blood cells, neutrophil, monocyte and eosinophil counts) and histology of some organs of rats. Methods: Fifteen healthy male Wister rats divided into control (Nm0) and experimental groups (Nm11 and Nm22). Control group 1 (Nm0) was given 100mg/200g body weight of normal saline orally twice daily; experimental group 2 (Nm11), 100mg/200g body weight neem extract twice daily for 11 days and experimental group 3 (Nm22), 100mg/200g neem leaf extract twice daily for 22 days. Total number of white blood cells (WBC), lymphocytes, neutrophils, monocytes and eosinophils, packed cell volumes (PCV) and histological changes in the spleen, liver and kidneys were evaluated. Results: There were no significant differences in mean values of the hematological parameters (total WBC; PCV; neutrophils, lymphocytes, monocytes and eosinophils). We observed the central vacuolation and accumulation of lymphocytes in the spleen, hypertrophy of the central vein in the liver and shrinking of the glomeruli and accumulation of the lymphocytes in the kidney using hematoxylin and eosin staining following prolonged administration of neem extract (Nm22). Conclusion: Prolonged administration of neem affected the histology of some organs of the rats more than the hematological parameters

The effect of cigarette smoking on the oxidant–antioxidant imbalance in patients with chronic obstructive pulmonary disease

Background Predisposing factors for chronic obstructive pulmonary disease (COPD) comprise endogenous genetic factors and exogenous factors such as positive and negative smoking, air pollution, inhalation of dust, and work-related chemicals. Because only a small percentage of smokers develop COPD, it is thought to arise as an outcome of environmental harm and a host’s response system, which boosts the tendency of the disease to arise. Objective To clarify the effect of smoking on the level of oxidant–antioxidant in patients with COPD. Patients and methods Thirty patients with COPD (20 smokers and 10 nonsmokers) and 40 healthy individuals (18 smokers and 22 nonsmokers) participated in this study. The investigations included measurement of malondialdehyde (MDA), superoxide dismutase (SOD) activity, catalase (CAT) activity, glutathione peroxidase (GPx), glutathione reductase (GR), vitamin C, and glutathione (GSH) content. Results SOD, CAT, GPx, GSH, GR, and vitamin C were significant lower (P<0.0001) among patients with COPD (smokers and nonsmokers) than in the control group, whereas the MDA levels were elevated (P<0.0001) in patients with COPD (smokers and nonsmokers) when compared with the control group. Moreover, the values of SOD, GSH, and GPx were significantly lower (P<0.001) in smokers with COPD as compared with nonsmokers with COPD. Finally, there was no significant difference in the level of MDA between patients with COPD (smokers and nonsmokers). Conclusion There is a significant reduction in the level of some antioxidants (SOD, GSH, and GPx) in smokers with COPD compared with nonsmokers with COPD, but other antioxidants (CAT, GR, and vitamin C) did not change significantly, whereas the oxidant levels (i.e., MDA) were relatively convergent in patients with COPD (smokers and nonsmokers). This, in turn, points to the modest role of smoking in the causation of oxidant–antioxidant imbalance in this diseas

Tunisian maturity-onset diabetes of the young: a short review and a new molecular and clinical investigation

Introduction/aims: Maturity-Onset Diabetes of the Young (MODY) is a monogenic non-autoimmune diabetes with 14 different genetic forms. MODY-related mutations are rarely found in the Tunisian population. Here, we explored MODY related genes sequences among seventeen unrelated Tunisian probands qualifying the MODY clinical criteria. Materials and methods: The GCK and HNF1A genes were systematically analyzed by direct sequencing in all probands. Then, clinical exome sequencing of 4,813 genes was performed on three unrelated patients. Among them, 130 genes have been reported to be involved in the regulation of glucose metabolism, β-cell development, differentiation and function. All identified variants were analyzed according to their frequencies in the GnomAD database and validated by direct sequencing. Results: We identified the previously reported GCK mutation (rs1085307455) in one patient. The clinical features of the MODY2 proband were similar to previous reports. In this study, we revealed rare and novel alterations in GCK (rs780806456) and ABCC8 (rs201499958) genes with uncertain significance. We also found two likely benign alterations in HNF1A (rs1800574) and KLF11 (rs35927125) genes with minor allele frequencies similar to those depicted in public databases. No pathogenic variants have been identified through clinical exome analysis. Conclusions: The most appropriate patients were selected, following a strict clinical screening approach, for genetic testing. However, the known MODY1-13 genes could not explain most of the Tunisian MODY cases, suggesting the involvement of unidentified genes in the majority of Tunisian affected families.

Comparative growth of jipe tilapia, oreochromis jipe and nile tilapia, oreochromis niloticus using regression modeling

Regression modeling analyses the relationship between two or more variables and can be used to predict the response variable from one or more independent variables. The present study uses linear regression analysis to evaluate the growth in the two fish species of genus Oreochromis, Nile tilapia and Jipe tilapia, under aquaculture conditions. The models were fitted using a collection of functions in the R-software library. The final models were selected using the goodness of fit criteria based on the coefficient of differentiation, the model p- values and Akaike information criteria. The significance of the linear relationship between predictor variables and the mean response was tested by comparing the computed standardized parameter estimates, whereas the confidence intervals were constructed to assess the uncertainty of predicting the response variable and determine outliers in the model. Generally, both species exhibited good condition during growth and all the measured water quality variables significantly afffected growth (p<0.05). However, only temperature and dissolved oxygen produced the most important linear relationship with fish weight. The study recommends that data from a controlled experiment should be used the determine the interactions between the two growth variables.

Liposomes as carriers in skin ageing

Ageing is an inevitable phenomenon. Similar to other organs, skin is also subject to an intrinsic ageing process. Additionally, skin ageing is also influenced by various environmental factors. Existing conventional formulations have limited efficacy because skin serves as a rate limiting barrier for percutaneous absorption of drugs. This has led to the evolution of various novel drug delivery systems. Among these liposomes have received considerable attention due to the numerous advantages they offer. Liposomes, submicroscopic spherical vesicles, were discovered in 1960’s. Since then, they have gained popularity as potential carriers for drugs, diagnostics, nutrients, vaccines and other bioactive agents. Liposomes find applications in pharmaceutical, cosmetics and other industrial fields. Various topical actives that have been found to be efficacious in delaying the signs of ageing have been formulated as liposomes resulting in enhanced delivery, biocompatibility, and reduced toxicity. This review focusses on therapeutic use of liposomes in skin ageing.

Using interactive web-based animations to help students to find the optimal algorithms of river crossing puzzles

To acquire algorithmic thinking is a long process that has a few steps. The most basic level of algorithmic thinking is when students recognize the algorithms and various problems that can be solved with algorithms. At the second level, students can execute the given algorithms. At the third level of algorithmic thinking, students can analyze the algorithms, they recognize which steps are executed in sequences, conditions or loops. At the fourth level, students can create their algorithms. The last three levels of algorithmic thinking are: the implementation of the algorithms in a programming language, modifying and improving the algorithms, and creating complex algorithms. In preliminary research related to algorithmic thinking, we investigated how first-year undergraduate computer science students of J. Selye University can solve problems associated with the second, third and fourth level of algorithmic thinking. We chose these levels because these levels do not require to know any programming language. The tasks that students had to solve were for example: what will be the route of a robot when it executes the given instructions, how many times we need to cross a river to carry everyone to another river-bank. To solve these types of tasks requires only good algorithmic thinking. The results showed that students reached 81.4% average score on tasks related to the execution of given algorithms, 72.3% average score on tasks where they needed to analyze algorithms, and 66.2% average score on tasks where students needed to create algorithms. The latter type of tasks were mostly various river-crossing problems. Even though, that students reached a 66.2% average score on these tasks, if we had accepted only solutions with the optimal algorithms (minimal number of river crossing), they would have reached only a 21.3% average score, which is very low. To help students find the optimal algorithms of river crossing puzzles, we developed several interactive web-based animations. In the last part of this paper, we describe these animations, we summarize how they were created and how they can be used in education. Finally, we conclude and briefly mention our plans related to our future research.

Body size dependent rate of oxygen consumption, ammonia excretion and o:n ratio of fresh water bivalve, lamellidens marginalis during summer season.

The study of molluscan animals is called Malacology and the study of molluscan shell is called as conchology. The scaling of metabolic rates with body mass is one of the best known and most studied characteristics of aquatic animals. We studied here how body size is related to rate of oxygen consumption, ammonia excretion and O: N ratio in Freshwater Bivalve Mollusc Lamellidens marginalis species in an attempt to know how body size specific changes affect their metabolism. The freshwater bivalve molluscs with specific body size i.e. small (76-79 mm in shell-length) and large (90-94 mm in shell-length) were chosen for experimental work from Bhima River at Siddhatek on April and May during summer. The adult bivalve molluscs with small body size reported high value in rate of oxygen consumption and O: N ratio but rate of ammonia excretion was low value in small body sized bivalves compared to large ones. The results are discussed in the flush of metabolic processes in fresh-water bivalve molluscs.

Identification of bioactive compounds and toxicity study of araucaria columnaris bark extract on human embryonic kidney cell line

Plants produce a diverse range of bioactive compounds making them a rich source of different types of medicines. Ornamental plants are cultivated for adornment and to enhance the appearance of houses and also for commercial purposes. However, only very few of these ornamental plant species have found to be used in medicine and only little literature exit on their chemical and biological actions. In the present study, the evaluation of antimicrobial activities and identification of bioactive compounds using TLC and GC-MS of the A. columnaris bark extract were performed. In GC-MS bioactive compounds with medicinal value were identified, such as Benzoic acid, 1H-N-Hydroxynaphth (2,3) imidazole-6,7-dicarboximide, 2-Propenoic acid, 3-(4-methoxyphenyl), 1H-N-Hydroxynaphth (2,3-d) imidazole-6,7-dicarboximi. To prove the nontoxic nature of the plant, its crude bark extract was subjected to toxicity study using human embryonic kidney cell line. It reveal that the plant is minimal toxic to the human kidney cell line so usage of appropriate level will found to be safe and also carrying out some structural modification will help in the extraction of new drugs for pharmaceutical purpose.

Financing ict smmes at different stages of the business life cycle

Small, medium and micro enterprises (SMMEs) represent a vital element in our economy in terms of addressing unemployment and the gross domestic product (GDP) of our country. Improving the success rate of SMMEs would save a lot of financial resources, thus understanding the financing options that complement success at different phases of the business is very important. This research sought to examine the extent to which the financing options chosen by entrepreneurs will have an impact on business success. The investigators adopted the progression of the ventures along the business life cycle stages as a benchmark for assessing success. The study focused primarily on SMMEs in the Eastern Cape Information Communication Technologies (ICT) sector. Data was obtained using an online survey which reached 50 small business owners/ business representative within the ICT sector in the Eastern Cape Province. The research study showed the role that internal financing options, such as personal savings, family, relatives and friends' financing, retained earnings, sale of existing assets and cutting down stock levels, play in the achievement of ICT SMME success. Moreover, examined external financing options such as Broad-Based Black Economic empowerment (B-BBEE) financing, bank loans, equity financing, government grants, trade credit, to SMME success. Key results revealed that the financial support of B-BBEE and personal savings have played a key role in the success of ICT SMMEs throughout the business life cycle phases. This occurs after an ICT SMME has advanced successfully over the start-up stage and aims for success in the development phase. The finding revealed that for these SMMEs to attain success at the development stage, they should finance their business investment projects utilising credit trade, bank loans, families, relatives and friends. The abovementioned financing options are only substantially linked to good advancement from the development phase onto the expansion phase. Also, suggestions have been made to the ICT SMME management to include B-BBEE finance, personal savings, bank loans, families, relatives and friends and trade credit as suitable funding choices for the ICT SMME's life cycle
