ANALYSIS OF ERRORS IN PARTS OF SPEECH IN LEARNING ENGLISH AS A SECOND LANGUAGE [WITH SPECIAL REFERENCE TO BENGALI LANGUAGE]
Mr. Zawad Rami
ABSTRACT Errors were no longer considered filthy signs of failure in teaching and learning. It is to eliminate anyhow rather they were seen as a necessary part of the language learning process. The study of L2 learners language includes what types of errors learners make in learning L2?, how their errors show their TL knowledge and ability to use the TL?, how L2 learners develop their interlanguage? And what factors influence their interlanguage? Several issues have been raised by the early researchers concerning the relationship of the L1 to the L2. They are: - the concept of Interference, the concept of Bilingualism and the Nature of L2 Learner’s Grammar. As many studies assume that the Bengali students are not strong in English and they encounter serious mistakes due to some reasons like-poor style of teaching them, the purpose of teaching them, use of textbook and the methods, focusing on the traditional method of teaching, lack of good and dedicated English teacher, lack of newer technology, lack of required funding. It is assumed that the Bengali speakers of English encounter intense difficulties in the form of mistakes, errors and lapses in the use of English. In the current study, the researcher touches on the three main areas of second language research; namely, Contrastive Analysis (CA), Error Analysis (including classification of errors suggested by applied linguistics) and Inter-language (IL). The goal of this paper is to define that what is an error and how to deal with them, the method of analyzing errors, the significance of error of learners and models of error analysis. Moreover, this paper shows a lot of differences and variations between Bengali-English grammar and spellings. How to Cite: Rami, Zawad et al (2022).

Land management for improving soil health and environmental quality: Can we achieve synergies?
Land management encompasses the management of soils, nutrients, crops, and water. When poorly implemented, such practices degrade soil productivity and increase soil and nutrient losses to water and air, thereby impairing environmental quality. Today, enhancing soil health and environmental quality are widely recognized as two fundamental objectives of sustainable land management. However, research efforts often address these goals separately, with soil- and water-/or gas-focused studies proceeding in parallel. Increasingly, stakeholders call for a better understanding of the synergies between soil health and environmental quality, as well as the management practices that can deliv...

সাম্প্রতিক সময়ে বছরজুড়ে দেখা দিয়েছে ডেঙ্গু আতঙ্ক। প্রতিদিনই কেউ না কেউ ডেঙ্গুতে আক্রান্ত হচ্ছে। ডেঙ্গুজ্বর হলে মাথাব্যথা, বমি, পেশিতে ও গাঁটে ব্যথা এবং চামড়ায় ফুসকুড়ি দেখা দেয়। দুই থেকে সাত দিনের মাঝে সাধারণত ডেঙ্গু রোগী আরোগ্য লাভ করলেও কিছু কিছু ক্ষেত্রে রোগটি মারাত্মক রক্তক্ষয়ী রূপ ধারণ করে। এমনকি মৃত্যু পর্যন্ত হতে পারে। বৈশ্বিক উষ্ণায়নের কারণে যেমন মশার প্রজনন বেড়েছে তেমনি জনসংখ্যা ও বাসস্থান বাড়ার কারণে এডিস মশার প্রজননের স্থানও বৃদ্ধি পেয়েছে। এক সময়ে ঢাকা ও চট্টগ্রামে ডেঙ্গুর প্রকোপ থাকলেও তা ক্রমান্বয়ে দেশের বিভিন্ন অঞ্চলে ছড়িয়ে পড়ছে। এর ফলে দেশের বিভিন্ন অঞ্চলের এডিস মশাতে ডেঙ্গুর ভাইরাসটি ছড়িয়ে পড়েছে। এসব মশা থেকে ডেঙ্গু মহামারি আকার ধারণ করতে পারে। ত...
Preliminary report on the comparative weed suppressibility of Bangladeshi Wheat varieties
A key and ecologically sound strategy for integrated weed management is the use of varieties of weed-competitive crops. Utilizing wheat cultivars that are weed-competitive can lessen weed pressure and inordinate herbicide usage in wheat fields by a substantial amount. To assess the weed suppressibility of Bangladeshi wheat varieties, a field test was carried out in 2018 throughout the winter season at the Agronomy Field Laboratory, Bangladesh Agricultural University, Bangladesh. Tests on a total of 18 selected Bangladeshi wheat cultivars were conducted in both “weedy” and “weed-free” environments. Additionally, weed monoculture plots (without wheat) w...

Photoperiodic light pulse induces ovarian development in the catfish, Mystus cavasius: Possible roles of dopamine and melatonin in the brain
In the freshwater catfish, Mystus cavasius, locally known as gulsha, ovarian maturation is triggered by long-day conditions. Using dopaminergic neuronal activity in the brain, the purpose of this study was to identify the brain’s detection of a nocturnal light pulse that induced ovarian development. Since direct inhibition of pituitary gonadotropin release is exerted by dopamine (DA), it may serve as a neuromodulator of photoperiodic stimulation in teleosts. We studied functional effects of photoperiodicity on dopaminergic rhythmicity in gulsha brain. Nocturnal illumination and Nanda-Hamner photocycles revealed that ovarian development is induced by a 1 h light puls...

Exopolysaccharides From Streptococcus thermophilus ST538 Modulate the Antiviral Innate Immune Response in Porcine Intestinal Epitheliocytes
Abstract: It was reported that exopolysaccharides (EPSs) from lactobacilli are able to differentially modulate mucosal antiviral immunity. Although research has described the ability of EPSs derived from Streptococcus thermophilus to modulate the mucosal immune system, their impact on antiviral immunity was less explored. In this work, we investigated the capacity of the EPS-producing S. thermophilus ST538 to modulate the innate antiviral immune response triggered by the activation of the Toll-like receptor 3 (TLR3) in porcine intestinal epitheliocytes (PIE cells). Moreover, in order to study the immunomodulatory potential of S. thermophilus ST538 EPS,...
Evaluation of the Immunomodulatory Ability of Lactic Acid Bacteria Isolated from Feedlot Cattle Against Mastitis Using a Bovine Mammary Epithelial Cells In Vitro Assay
Abstract: Bovine mastitis, the inflammation of the mammary gland, affects the quality and quantity of milk yield. Mastitis control relies on single or multiple combinations of antibiotic therapy. Due to increasing antibiotic resistance in pathogens, the intramammary infusion of lactic acid bacteria (LAB) has been considered as a potential alternative to antibiotics for treating and preventing bovine mastitis through the improvement of the host immunity. Probiotic effects are a strain-dependent characteristic; therefore, candidate LAB strains have to be evaluated efficiently to find out the ones with the best potential. Here, we investigated LAB strains originally isolated from...
The Role of Alveolar Macrophages in the Improved Protection against Respiratory Syncytial Virus and Pneumococcal Superinfection Induced by the Peptidoglycan of Lactobacillus rhamnosus CRL1505
Abstract: The nasal priming with nonviable Lactobacillus rhamnosus CRL1505 (NV1505) or its purified peptidoglycan (PG1505) differentially modulates the respiratory innate immune response in infant mice, improving their resistance to primary respiratory syncytial virus (RSV) infection and secondary pneumococcal pneumonia. In association with the protection against RSV-pneumococcal superinfection, it was found that NV1505 or PG1505 significantly enhance the numbers of CD11c+SiglecF+ alveolar macrophages (AMs) producing interferon (IFN)-β. In this work, we aimed to further advance in the characterization of the beneficial effects of NV1505 and PG1505 in the co...
Evaluation of Fat Accumulation and Adipokine Production during the Long-Term Adipogenic Differentiation of Porcine Intramuscular Preadipocytes and Study of the Influence of Immunobiotics
Abstract: The degree of fat accumulation and adipokine production are two major indicators of obesity that are correlated with increased adipose tissue mass and chronic inflammatory responses. Adipocytes have been considered effector cells for the inflammatory responses due to their capacity to express Toll-like receptors (TLRs). In this study, we evaluated the degree of fat accumulation and adipokine production in porcine intramuscular preadipocyte (PIP) cells maintained for in vitro differentiation over a long period without or with stimulation of either TNF-α or TLR2-, TLR3-, or TLR4-ligands. The cytosolic fat accumulation was measured by liquid chromatography and the...
A Pigeon-Derived Sub-Genotype XXI.1.2 Newcastle Disease Virus from Bangladesh Induces High Mortality in Chickens
Newcastle disease virus (NDV) is a significant pathogen of poultry; however, variants also affect other species, including pigeons. While NDV is endemic in Bangladesh, and poultry isolates have been recently characterized, information about viruses infecting pigeons is limited. Worldwide, pigeon-derived isolates are commonly of low to moderate virulence for chickens. Here, we studied a pigeon-derived NDV isolated in Bangladesh in 2010. To molecularly characterize the isolate, we sequenced its complete fusion gene and performed a comprehensive phylogenetic analysis. We further studied the biological properties of the virus by estimating mean death time (MDT) and by experimentally in...
Surveillance on respiratory diseases reveals enzootic circulation of both H5 and H9 avian influenza viruses in small-scale commercial layer farms of Bangladesh
Poultry production in Bangladesh has been experiencing H5N1 highly pathogenic avian influenza (HPAI) and H9N2 low pathogenic avian influenza (LPAI) for the last 14 years. Vaccination of chickens against H5 HPAI is in practice since the end of 2012. Subsequently, the official reporting of HPAI outbreaks gradually decreased. However, the true extent of circulation of avian influenza virus (AIV) in commercial poultry production is not clear. To explore this, we conducted active surveillance in 422 small-scale commercial layer farms in 20 villages of Mymensingh and Tangail districts of Bangladesh during 2017 and 2018 for the presence of diseases with respiratory signs. A total of...

The early clinical signs like fever, depression, and ocular and nasal discharges first appeared at 4–7 days post-infection (dpi). Three out of eight inoculated goats died at 13, 15, and 18 dpi, and the rest were killed at different time points from 5 to 18 dpi. Initially, the virus multiplied mostly in the lymphoid organs of the pharyngeal region and caused extensive lymphoid destruction and hemorrhages. This was followed by viremia...
Genetic and biological characterization of Newcastle disease viruses circulating in Bangladesh during 2010–2017: further genetic diversification of class II genotype XIII in Southcentral Asia
Newcastle disease virus (NDV) is endemic in Bangladesh and is a major threat to commercial poultry operations. While complete fusion (F) genes are recommended for molecular characterization and classification of NDV isolates, heretofore, only partial F gene data have been available for Bangladeshi NDVs. To this end, we obtained the full-length F gene coding sequences of 11 representative NDVs isolated in Bangladesh between 2010 and 2017. In addition, one of the viruses (MK934289/chicken/Bangladesh/C161/2010) was used in an experimental infection of chickens to establish the viral pathotype and study gross and microscopic lesions. Phylogenetic analysis provided evidence that all stu...
A unified genotypic classification of infectious bursal disease virus based on both genome segments
Infectious bursal disease virus (IBDV) of chickens is a birnavirus with a bi-segmented double-stranded RNA genome, the segments designated as A and B. We performed phylogenetic analysis using a 366-bp fragment of segment A (nt 785–1150) and a 508-bp fragment of segment B (nt 328–835) of IBDV. A total of 463 segment A and 434 segment B sequences from GenBank, including the sequences of eight recent Bangladeshi isolates, were used in the analysis. The analysis revealed eight genogroups of segment A under serotype 1, designated as A1 (classical), A2 (US antigenic variant), A3 (very virulent), A4 (dIBDV), A5 (atypical Mexican), A6 (atypical Italian), A7 (early Australian) a...
Weeds and Their Responses to Management Efforts in A Changing Climate
Crop production is a constant battle with weeds, in which weeds, generally, are victorious. Therefore, rather than channeling our efforts into the development of a “silver bullet” to control weeds, the focus should be on sustainable weed management in both natural- and agro-ecosystems. However, sustainable weed management can be a challenge in the context of global climate change. Over the past few decades, global climate change, mostly indicated by phenomena such as increased atmospheric temperature and elevated CO2 levels, is evident due to human activities and natural events. These phenomena also affect regional/local climate, resulting in significant influences...

Immunobiotic Lactobacillus jensenii TL2937 Alleviates Dextran Sodium Sulfate-Induced Colitis by Differentially Modulating the Transcriptomic Response of Intestinal Epithelial Cells
Abstract: Immunobiotics have emerged as a promising intervention to alleviate intestinal damage in inflammatory bowel disease (IBD). However, the beneficial properties of immunobiotics are strain dependent and, therefore, each strain has to be evaluated in order to demonstrate its potential application in IBD. Our previous in vitro and in vivo studies demonstrated that Lactobacillus jensenii TL2937 attenuates gut acute inflammatory response triggered by Toll-like receptor 4 activation. However, its effect on colitis has not been evaluated before. In this work, we studied whether the TL2937 strain was able to protect against the development of coli...

Emerging potential of cannabidiol in reversing proteinopathies
The aberrant accumulation of disease-specific protein aggregates accompanying cognitive decline is a pathological hallmark of age-associated neurological disorders, also termed as proteinopathies, including Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis and multiple sclerosis. Along with oxidative stress and neuroinflammation, disruption in protein homeostasis (proteostasis), a network that constitutes protein surveillance system, plays a pivotal role in the pathobiology of these dementia disorders. Cannabidiol, a non-psychotropic phytocannabinoid of Cannabis sativa, is known for its pleiotropic neuropharmacological e...
Potential Therapeutic Role of Phytochemicals to Mitigate Mitochondrial Dysfunctions in Alzheimer’s Disease
Abstract: Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by adecline in cognitive function and neuronal damage. Although the precise pathobiology of AD remainselusive, accumulating evidence suggests that mitochondrial dysfunction is one of the underlyingcauses of AD. Mutations in mitochondrial or nuclear DNA that encode mitochondrial componentsmay cause mitochondrial dysfunction. In particular, the dysfunction of electron transport chaincomplexes, along with the interactions of mitochondrial pathological proteins are associated withmitochondrial dysfunction in AD. Mitochondrial dysfunction causes an imbalance in the productionof reactive ox...
The potential LXRβ agonist stigmasterol protects against hypoxia/reoxygenation injury by modulating mitophagy in primary hippocampal neurons
Background: Neuronal excitotoxicity induces a plethora of downstream signaling pathways, resulting in the calcium overload-induced excitotoxic cell death, a well-known phenomenon in cerebrovascular and neurodegenerative disorders. The naturally occurring phytosterol, stigmasterol (ST) is known for its potential role in cholesterol homeostasis and neuronal development. However, the ability of ST to protect against the induced excitotoxicity in hippocampal neurons has not been investigated yet. Purpose: The present study aimed to investigate whether ST could protect against hypoxia/reoxygenation (H/R)-induced excitotoxicity in hippocampal neurons. Methods: After H/R, neurons were i...
Weed science as a new discipline and its status in some South Asian universities and colleges: examples from Bangladesh, Bhutan, Nepal and Pakistan
Agriculture is the most important sector of the economy and livelihood in South Asia. Of the many biotic stresses in agriculture, weeds pose a continuous threat and cause considerable yield losses in the major crops. In the past, ample human labour was available for weed management in South Asia. However, in recent years, there has been a steady decline in labour availability in this region due to migration to other better-paying sectors. Thus, farmers are rapidly adopting less labour-intensive, chemical weed control methods. Adoption of chemical control methods requires formal and nonformal education in herbicide mode of action, safety and weed biology. We emphasize that sound for...
O-aryl and Carbonyl Carbon Contents of Food Waste and Biosolid Predict P Availability in an Acidic Soil
Organic waste streams, otherwise known as organic amendments (OA), containpotentially valuable nutrients which may additionally increase legacy nutrient availabilityin soil. This is particularly the case for phosphorus (P) where declining reserves ofrock phosphate add an extra dimension to their utility. In acidic soils, OA have beenreported to increase P availability through the action of O-aryl and carbonyl groups(represent organic acid compounds) by substituting previously fixed, legacy P andforming organometallic complexes to reduce P sorption. This study aimed to investigateif signature P (orthophosphate) and C (O-aryl and carbonyl) content of OA could beused to predict soil P...

Assessment of allelopathic compounds to develop new natural herbicides: A review
Herbicides are a crucial tool for weed control in crops. However, their continuous and indiscriminate uses have caused environmental pollution and development of weed resistance. Hence, there is an urgent need to minimise the dependence on synthetic herbicides. Allelopathy may be used to develop new bioherbicides to inhibit germination and growth of weeds. There is a great potential to develop eco-friendly herbicides from plants, but little research has been done so far in this context. Identification and quantification of natural weed control compounds (allelochemicals) of plants may help to develop natural herbicides (based on indigenous/invasive weed species), to reduce the depe...
