Authors: Bioud Nadhira
Published: March 2023

In the present work we used the experimental relative volume unit cell and the elastic stiffness constants measured by Speziale et al. (Journal of Geophysical Research, Vol. 111, (2006), pp. B02203 (12 pages)) using the Radial X-Ray Diffraction at high pressure from 5.6 up to 65.2 GPa to investigate the effect of high pressure on the bulk modulus, aggregate shear modulus, elastic wave velocities and Debye temperature of calcium oxide (CaO) ceramic material in cubic rock-salt (B1) phase. Our obtained values show that the bulk modulus increases monotonously with increasing pressure, while the aggregate shear modulus, the mean elastic wave velocity and the Debye temperature of CaO material varied non-linearly and non-monotonously with increasing pressure from 5.6 up to 65.2 GPa.

Published: March 2023

Copper (II) complexes with commercial antibiotics, amoxicillin (AMX), azithromycin (AZT) and ciprofloxacin (CFL) were synthesized and isolated as solids. Structures of the isolated products were determined by FTIR spectroscopy. Antibacterial activities were determined on reference bacterial strains from the ATCC collection by diffusion technique. The results show that AMX and CFL coordinate Cu (II) ion as bidentate O-donor ligand. AZT coordinates metal center as bidentate NO-donor ligand. A difference in the morphology of antibiotic crystals and the synthesized complexes was found. Complex of Cu (AMX)2 show complete absence of antibacterial activity, while the other com-plexes show the same or even lower activity than the parent ligands.

3D seismic interpretation and prospect evaluation has been carried out in a hydrocarbon bearing field, standard method of seismic interpretation which includes fault interpretation, well-seismic tie, and horizon mapping were carried out with the aid of seismic attributes such as variance edge and root mean square attributes. Well-seismic-tie established a reasonable tie and indicated that the identified reservoirs were of low impedance as the top of this reservoirs coincided with the troughs. TWT vs Depth plot showed a linear trend which aided in creating a velocity model for the time-depth conversion. Fault mapping revealed that the area was divided into 8 blocks by regionally extensive faults associated with several minor faults which are normal and listric in geometry. Petrophysical analysis showed that the reservoirs has an average porosity of 0.24, water saturation of 0.35, and net-to-gross of 0.78 which are favourable reservoir conditions. A lead Dembe-3, and 2 prospects Dembe-1 and Dembe-2 were identified. Volumetric estimation shows that the prospects boasts of a combined petroleum reserve of about 134 MMSTB of recoverable oil and about 167 BCF of recoverable gas. The results from this study show that, away from currently producing zones of the Dembe field, additional lead and prospects exist which could be further explored to optimize hydrocarbon production in the field.Â Â

Petrography and geochemical outline studied carried out on BÃ©rem dolerites have shown that they crosscut the local granitoÄ±ds of the basement toward N100-120, EW and N160E directions. Individual dyke may have 5 m to 50 m wide and extend along strike on 200 m to 3 km. Microscopic observations have distinguished the lavas of doleritic textures of ophitic to sub ophitic types. ICP-AES and ICP-MS geochemical analyses of representative samples have distinguished the lavas of basaltic trachyandesite of normative quartz-hypersthene compositions. All lavas belong to the same lavas series of continental tholeiites affinity which have undergone the fluids circulation and crustal contamination processes. Mantle of BÃ©rem dolerites should be E-MORB mantle component which have experienced the relatively high partial melting rate. BÃ©rem dolerites should be considered as imprints of late Pan African relaxation phase which cracks should have been filled by dolerite lavas.
Reservoir characterization using integrated seismic attributes and petrophysical parameters in an onshore field of Niger delta basin
Authors: SOFOLABO ADEKUNLE , NWAKANMA ALEXANDER
Published: March 2023

An integrated approach of reservoir characterization of a field was performed using seismic attributes and petrophysical parameters for the evaluation of subsurface geological features and hydrocarbon potential of an onshore field in Niger Delta Basin. Four reservoir intervals were identified within the field wells based on their position within the stratigraphic column, and the reservoir correlation, which was aided using the principle of uniform horizontality, based on the simple rule that sediments are deposited horizontally and basic understanding of sequence stratigraphy. The study revealed that, the four reservoirs were predominantly sand units intercalated with shale within the reservoir units. The petrophysical evaluation revealed the Net to Gross (NTG) values ranges from 79% to 87% within the reservoir units, while the effective porosity ranges from 17% to 21%, the permeability ranges between 1307mD to 1678mD across the reservoir units, while the water saturation ranges from the lowest of 35% (Reservoir C) to 78% in reservoir D. A total of fifteen faults were interpreted using the seismic data, while the surface maps (Time and depth surface maps) revealed the identified closures which are anticlinal structures that are fault dependent. The characterization of the reservoir was further enhanced using the seismic attributes (structural and stratigraphic) extracted such as Reflection intensity, Sweetness, Variance, Envelope, Instantaneous frequency, Time gain, Trace AGC, Local structural dip, Gradient magnitude and RMS amplitude. The results shows moderate to high sweetness (sweet spots) within the zone of interest, while the Envelope attribute show acoustic impedance contrasts indicating discontinuities, lithology changes and possible present of hydrocarbon (Bright spots). The variances and gradient magnitude enhanced the signal to map out discontinuities caused by faults and fractures which are signature that enabled delineation of the zone. The integrated approach validates the lithology discrimination of the elastic properties from the well logs and its effectiveness in optimizing and proper understanding of the subsurface, thus identifying and unmasking hidden features within the reservoir (probable bypass) in the field. The study has revealed that the integration of seismic attributes with petrophysical parameters is a better characterization method for fluid and lithology discrimination of a field in any given reservoir study.

Authors: Hossain MD. Babul , Kundu Bishwajit
Published: March 2023

This study compared the profitability of tossa and kenaf seed cultivation based on the 2021 seed-growing season in two locations: Rangpur and Jashore using the tossa variety BJRI Tossa Pat 8 and Rangpur and Kishoreganj using the kenaf variety HC-95. Data analysis methods included descriptive statistics, break-even analysis and cost-benefit analysis. The expensive factors in growing tossa and kenaf seeds were labor costs, followed by land use, machinery, fertilizers, and seed. While the cost of labor (58.38%) and fertilizers (8.74%) were higher for tossa seed, the cost of seed (4.85%) for kenaf seed cultivation was higher as a percentage of the total cost. The highest tossa and kenaf seed yields were 722 kgha-1 and 798 kgha-1, respectively, in Jashore and Kishoreganj. Average break-even price for kenaf seed was Tk. 130 kg-1, which was less expensive than tossa seed (Tk. 181 kg-1). When compared to kenaf (341 kgha-1), average break-even quantity of tossa seed was higher (679 kgha-1). The average benefit cost ratio was found higher in the kenaf seed crop, as compared to the tossa seed crop in respect of total cost, variable cost, and cash cost. According to this finding, growing kenaf as seed crop can be profitable for farmers.

Authors: Rotich Titus , Chepkwony Jacob , Lagat Robert , Bitok Jacob
Published: March 2023

The study of epidemiology is often done with an assumption that the population is homogeneously mixed, and the disease dynamics is uniform. However, this is not always true, and cultural beliefs and economic activities significantly contribute to segregation not necessarily in spatial dimension but on the way of life. In this study, the dynamics of HIV/AIDS is studied in four distinct fisher-folk population patches, both individually and under all-to-all diffusive coupling. It was found that, the dynamics of each patch is periodic, and there exist an attracting invariant stable synchronization manifold. The manifold of the coupled system displayed robustness under small perturbation, even with a small coupling strength of k≪1. This guarantees uniformity of long term metapopulation disease dynamics.

Nursing role in early detection of cardiac amyloidosis: a case report
Authors: Eid Al shammari Noof
Published: March 2023

Cardiac amyloidosis (CA) is a rare health condition that occurs due to amyloid deposits in the heart's tissues, it causes restrictive cardiomy-opathy, which leads to heart failure and death. This report discusses a case of 72-year-old Saudi male known case of hypertension, diabetes mullets, left ventricular dysfunction, and chronic kidney dysfunction presented to hospital with shortness of breath, paroxysmal nocturnal dyspnea, and orthopnea. Patient's physical examination revealed jugular vein distention, generalized pitting edema and abdominal distension. Echo image exhibited abnormal myocardial texture with moderate global hypokinesia, left ventricular D shape, and thickened interatrial sep-tum. CA diagnosis is complex, and its diagnostic accuracy is relatively limited. Delay in CA diagnosis continues to challenge clinicians, which has adverse effects on patient's quality of life, and mortality rate. Underdiagnosis mainly because disease has nonspecific symptoms which often associated with poor prognosis. To aid in early diagnosis and treatment, nurses should be aware about symptoms, diagnostic approach, and disease progression of CA.

Published: March 2023

Cobalt doped modified borophosphate glasses similar to Henchâ€™s bioglass were successfully synthesized using gradually increasing cobalt ions in addition to another sample of Co free glass. Synthesized samples were studied for their bioactivity through immersion in phosphate solution for different time intervals. FTIR absorption spectral data were collected before and after immersion for a prolonged time intervals. Spectral data reveals appearance of absorption band at 573 cm-1 Splitted into 565 cm-1 and 603 cm-1 after one week of immersion supporting the bone bonding ability and biocompatibility with bone. The change in the calculated N4 value also indi-cate the conversion of both BO3 and BO4 strutural units associated with the formation of hydroxyapatite. Magnetic characteristics meas-ured and calculated through VSM measurements supporting the idea of using such material as a bioactive material that can be used in hyperthermia treatment.Â Â

Published: March 2023

In this paper it is shown the experimental measurements made of the generated radiation by mobile phones, and the corresponding conclusions when comparing them with the values provided by the manufacturers. The so-called specific absorption rate (SAR) is calculated from the amount of electromagnetic energy emitted by mobile phones and absorbed by the human body. It was found that the measurements obtained are within the allowed values, which suggests that the radio frequency emitted by these mobile phones does not have negative effects on human health. These devices have a SAR value provided by the manufacturers, but such values are not completely reliable However, the possibility that its use may cause other harm to human health is not ruled out. The measurements and experimental results were part of the development of a project at a Public University in Mexico City.Â Â

Published: March 2023

The agriculture sector is of great importance to the development of any nation in Africa; hence, it is determined by the operating climatic mechanisms of such nation, especially rainfall. This study was carried out to assess the inter-annual rainfall variability impacts on cash crop yield in Ondo state for a period of twenty years (2000-2019). The study employed mainly secondary data which was analyzed using inferential statistics. Trend analysis was used to determine the pattern of rainfall and cash cropsâ€™ yield for the period under review. Also it was revealed that there were fluctuations in the trend of rainfall and the yield of cash crops. The correlation analysis showed a significant relationship between rainfall and cash crops yield; but an inverse relationship with rubber yield specifically. On the other hand the regression analysis showed little impact of rainfall variability on cash crop yield. However, it was recommended that in this era of dwindling economy due to over reliance on crude oil in Nigeria, the government through National Orientation Agency and Non-governmental Organizations should keep persuading and enlightening Nigerians to venture into agriculture to save the countryâ€™s economy and reduce poverty.Â Â

Previously, by analytical method, some authors have shown that the harmonic noise is more indicated in the aggregation of deoxy-hemoglobin S. The problem that still arises is the relationship between the energy spectra and the microscopic properties of dielectric substances. The numerical approach of the correlation functionâ€™s Fourier transform of different random processes have permit to obtain the frequency distribution spectra of energy and the fluctuations of the amplitudes. The results have shown that (i) only a fine analysis of the curves can permit obtain sufficient precision on the noise indicated in the aggregation of deoxy-hemoglobin S, (ii) in the presence of harmonic noise, the frequency distribution of energy and fluctuations of the amplitudes are low compared to white and colored noise, (iii) method exploiting the frequency distribution of energy and the fluctuations of the amplitudes justify well that the harmonic noise is the best indicated in the aggregation of the deoxy-hemoglobin S.Â Â
Principal centrality measures: a comprehensive approach to the Spanish stocks market
Authors: Gutierrez Amauri
Published: March 2023

In social network analysis, for determining the relevance or significance of a node in the network, several node centrality measures are often used such as degree centrality, betwenness centrality, closeness centrality, eigenvector, subgraph and page rank centrality. In this paper we apply a principal components analysis over the traditional centrality measures for obtaining an overall single metric that combines the best attributes of the traditional centrality measures and permits to detect relevant nodes in the network. Concretely, a detailed study of the Spanish stocks market will be used for demonstrating the advantages of this approach.

Authors: Yamadjako A. E. , Adomou A. , Houngan A. C.
Published: March 2023

In this work, exact analytical static spherical symmetric solutions to the nonlinear interacting electromagnetic and massless scalar field equations have been determined taking into account the proper gravitational field of elementary particles. The obtained results prove that all solutions of the Einstein equation and those of the interacting fields are regular with localized energy density. All non-zero components of the 4-vector potential are solutions to the inverted PainlevÃ©-Gambier XI equation. Moreover, the total energy of interacting fields is limited and the total charge of elementary particles is finite. These solutions obtained are soliton-like and can be used as a model to describe the internal structure of elementary particles.

Authors: Alshammary Dr. Heba , Abumismar Dr. Munther
Published: March 2023

Background: According to WHO, the new COVID-19 cases are rising with 4.5 million new cases in the first week of April 2021 and over 76000 new deaths globally. The risk of COVID-19 transmission in dental settings has been a concern. Therefore, this study aims to assess the transmission risk in dentistry and review the infection-control measures followed in different dental clinics worldwide and their compliance with the standard country-based or international guidelines.Methods: This study reviewed the published literature regarding the COVID-19 transmission-control guidelines followed by different dental care centers worldwide. We performed a comprehensive literature search in PubMed and Embase databases. The key guidelines were listed study-wise, divided into three parts: before entering the dental treatment, during the dental procedure, and after the dental procedure. A comparison study was conducted to assess the compliance with the country-based or internationally accepted recommendations given by WHO, ADA, CDC, etc., for dental practices in the COVID-19 pandemic.Results: During the dental procedure, a rubber dam and high volume saliva ejectors are recommended to minimize aerosol diffusion; mouth rinsing with 1% hydrogen peroxide or 0.2% povidone-iodine is recommended for patients. After the treatment, proper disinfection of the surfaces and instruments must be followed; the reusable dental instruments should be sterilized. Different guidelines were followed in different dental settings depended on the geographical locations; however, the most commonly followed guidelines were provided by WHO, ADA, CDC, and NHS.Conclusions: The available guidelines will contribute to the prevention of COVID-19 in dental settings. Although the dental clinics are adopting standard guidelines to prevent COVID-19 transmission, the joint efforts and cooperation of both patients and dental practitioners are needed to make it successful. Therefore, both parties should strictly adhere to their respective recommended guidelines and hand hygiene practice in dental settings.

Pediatric professionals treat natureâ€™s most benevolent creation i.e., the child.It is important to focus not only on oral health but also on the overall health of the pediatric patient because oral health is an integral part of total development.There are various dental materials ranging from diagnosis to rehabilitation for the management of oral diseases that are not devoid of posing a potential risk of inducing allergic reactions to Pediatric patients in the dental setting.Most importantly, a dental practitioner must be trained in medical emergencies and be capable of resuscitating a patient. Not only the dentist but also the assistants present in the clinic should be trained on how to manage any allergic emergency conditions in children in dental settings.As some of these diseases have higher rates of morbidity and mortality, management of such conditions requires a multidisciplinary medical team approach consisting of physicians, dermatologists, Pediatric dentists, and ophthalmologists.So, this review involves in-detail information regarding what is an allergy, history of allergy, allergic and immunological responses of the oral mucosa, dental materials prone to allergies, its diagnosis, and treatment modalities in child hoping that it will be helpful to every practicing pediatric professional.Â Â
Multiple dental retentions: literature review
Authors: Maftouh B. , Khazana M. , Alami S.
Published: March 2023

Multiple dental inclusions are a relatively rare pathology. They are often part of complex dysmorphoses which require an interrogatory, clinical and radiological examination. The most frequent etiologies of inclusion are local. However, the presence of multiple inclusions can also be correlated with genetic syndromes or metabolic or hormonal pathologies, as well as idiopathic etiologies. There are as many therapeutic approaches as there are forms of inclusions; therapeutic abstention, extraction followed by prosthetic restoration or surgical-orthodontic treatment. Developing a treatment sequence, determining the appropriate anchorage, and biomechanical planning can be a challenge. The aim of our work is to establish an up-to-date state of knowledge regarding the epidemiology, etiological factors and appropriate treatment strategies for multiple dental inclusions.Â Â Â

Authors: Nadhim Kadhim B. D. S. M.Sc. Hala
Published: March 2023

Background: It has long been suspected that oral diseases could have an effect on pregnancy outcomes in different countries. This study described the dental caries incidence among pregnant women and examined its relationships to their oral health and behavior.Patients and Methods: Two hundred pregnant women were invited to participate in this study. Their ages ranged between 18-40 years. They were inspected at Maternal and Child Hospital as well as the College of Dentistry during the period from January to October 2021. Maternal variables were identified as medical history, previous pregnancy, dental history, presence of any dental complaints during pregnancy and oral hygiene practice. Screening for mothersâ€™ dental caries was carried out using the decayed, missing and filled Teeth index.Results: Among 200 women who delivered during the study period 28 (14%) women had dental caries. Among them 16 (6%) women were treated for dental caries. Mother's education, women with >3 children in rural regions were significantly associated less with the incidence of dental caries. While, tobacco use or passive smoking has no relationship with occurrence of dental caries. Mothers who did not brush their teeth believed that they could lose a tooth with dental caries only because they were pregnant (66.7%) in comparison to regular twice a day brushing (6.8%). A group of women (56%) were visited dentists regularly either before or during their last pregnancy had less frequently dental caries. Significantly higher dental caries (17.9%) were associated with preterm birth.Conclusions: Women in this study had a high prevalence of dental diseases and knew little about dental care during pregnancy. These results will be helpful in planning oral health programs for pregnant women.Â Â

A learning system that was directly face-to-face in class, had to be substituted with a learning system that is virtually integrated with the inter-net (online learning). The system uses online learning that connects teaching staff with the learning participants. Tiredness and laziness start-ed to be felt among the participants. This is worried to affect nonoptimal learning outcomes. During lessons, teaching staff often focuses on learning materials without knowing the emotions of their learning participants. Indirect online learning becomes a new challenge in adaptation; teaching staff and learning participants are required to adapt to existing conditions. With the problems above, the writer has an idea in devel-oping a prototype system that is developed to be able to help teachers in evaluating manners and emotions of students in online learning. Facial detection is a technology for detecting facial features such as the nose, eyes, and mouth. Development of facial detection that has un-dergone upgrades until now can differentiate if something is a facial feature or not and detect more than one face. This research aims to help teaching staff in evaluating learning participantsâ€™ affective behavior online by applying a Convolutional Neural Network method that has been trained to be able to predict emotional extents through facial expression.Â Â

The length of a fiber is very important property. The product which should be manufactured is depends on the perfect length of fiber. There are so many natural long staple fibers. Among them jute fiber plays an important role in Indian-subcontinent because in this climate jute plant grows well and we get good qualities jute fiber. But it a matter of great sorrow that our farmers are illiterate and they have no idea about the time limit of retting. Sometimes jute fibers are rated too much long time around 40 to 50 days and sometimes below 30 days. For this reason different length fibers have got on the duration of retting limit. Here the article is about effect on this retting process and it should be identified that how long retting is suitable for getting good length jute fiber. In this article it is shared about the information of length deviation from between these durations. Itâ€™s known to us all the fibers are not textile fibers, so for achieving good textile product itâ€™s needed to use the proper length of fibers.Â Â

Wood is a material used in construction, in instrument making, etc. In Benin, for heavy construction and construction on wetland, species with high technological characteristics are imported. But the performance of these imported species compared to local indigenous or exotic species remains to be verified. Thus, it is necessary to determine the basic technological properties of these species. It is within this framework that we have, on 500mmÃ—20mmÃ—20mm prismatic wood specimens of Anogeissus leiocarpus, Manilkara multinervis and Cylicodiscus gabunensis, used the acoustic method BING (Beam Identification by Non-destructive Grading) of CIRAD-Forest to determine the density Ï, the moduli of Young's modulus E, shear modulus G and the internal friction tanð›¿ and then evaluated the modulus of specific stiffness E/Ï. On other 20 mm edge cubic specimens, we evaluated the reference physical properties of density, infradensity, total shrinkage, radial shrinkage, tangential shrinkage and shrinkage anisotropy. It appears that the wood of Anogeissus leiocarpus and Manilkara multinervis present better physico-mechanical characteristics than those of Cylicodiscus gabunensis. Anogeissus leiocarpus and Manilkara multinervis are very dense woods with physico-mechanical characteristics better than those of most Benin's popular species. The average modulus of elasticity in bending of these two species is higher than 12000 MPa while that of Cylicodiscus gabunensis is 10713 MPa. In compression all these species have an average modulus of elasticity above 14100 MPa.Â  Cylicodiscus gabunensis wood tested is light with a lower shrinkage anisotropy than the other two species studied and have excellent acoustic properties. Its average specific stiffness (14 GPa) is higher than that of the other two species studied (12 GPa). The good physical-mechanical and acoustic properties of these species show that they are good structural timbers with also good potential for instrument making and acoustic insulation.Keywords: BING; Construction; Infradensity; Modulus of elasticity; Shrinkage anisotropy; Timber.

SBR is a system of treatment that relies on activated sludge and consists of a group of processes occurring in the same tank to obtain a wastewater treatment. In this study, the SBR combined with the filter has been applied to treat domestic wastewater in Basra city. The treat-ment unit consists of a domestic wastewater collection tank (250 L), an SBR tank with dimensions of (60x50x30) cm. this tank contains a mixer, diffuser for aeration, and an open hole at a height of (0.15 cm) for the discharge of treated water to the filter which consists of tank (60x70x30) cm. and two layers of gravel, the first layer with a diameter (2/5 â€“ 6/5) mm. and the second layer with adiameter (6/5 â€“ 9/5) mm. with the thickness of 7cm for each layer. The results of removal pollutants for domestic wastewater (COD, BOD, PO4, SO4, and NO3), for SBR alone, were (93%, 93%, 52%, 10, and 65%) respectively and for SBR combined with filter for the same pollutant, the removal values were as follows (97%, 96%, 56% 29%, and 70%) respectively.

The almost irreversible and encouraged link between connectable computer terminals and playful juvenile occupation raises the issue of parental education in the family environment. The latter is characterized by its narrowness and the almost daily absence of parents, hence the question of the uncontrolled use of tablets and smartphones connected by Middle School students from Pikine. Thanks to qualitative methods and semi-structured interviews with fourteen (14) teenagers and their parents, we discover that fathers and mothers are missing from homes on a daily basis because of work. They give to their offspring these devices and the connection not only to occupy them usefully but also to protect them from the evil temptations of the outside. Free, these young people, devote themselves to video games, sports, music, pornography, etc. offered by different websites. Thus, they idealize and copy bad models taken from the net. Conflicts with parents arise. Sanctions follow and the most painful is the withdrawal of the devices.Â Â

Geographic and linguistic distances are becoming less relevant due to digital technology advances. Due to digitalization, E-commerce is one of the many technological breakthroughs that have directly and indirectly impacted consumers' lives. With the rise of e-commerce, consumers may more easily choose items that meet their interests, and quality and reputation can be verified. For this reason, e-commerce businesses have risen to prominence in consumers' lives. Customers may engage with sellers and buyers via online and mobile platforms for a unique selling or purchasing experience because the e-commerce industry relies on digital technologies. But with time, this market became opaque due to the monopolistic practices of some of the world's largest e-commerce companies, who began to exert influence over consumer purchasing habits. Those players' interests must be safeguarded in a country like India, where small retail firms control more than 80 percent of the retail segment. As a measure, the Indian government developed a new concept called Open Network for Digital Commerce (ONDC) to protect merchants and buyers. When it comes to online shopping, this ONDC architecture is going to have a significant impact. Without a doubt, ONDC is addressing numerous concerns regarding future Indian e-commerce challenges, even though it is unclear what ONDC aims to achieve with the network's many building pieces or what privacy and security protections it intends to put in place for data interchange. All the befits and challenges of ONDC are highlighted in this article.Â
Comparison between simplex roller gauge of 40.5Ã—50Ã—52 mm and 39.5Ã—49.5Ã—50.5 mm

Simplex machine plays a vital role in spinning process. By using simplex machine the roving has been found, which reduced maximum draft in the ring frame. So it is necessary to produce good qualities roving from simplex machine. For this reason the draft and amount of false twist has been kept at a particular ration. For controlling draft, the drafting arrangement needed to arrange in a proper order. The gauge distance between the drafting zones are needed to maintain at a particular distance, through which the production and the quality of the product will be optimum level. Here for the research work the simplex machine drafting arrangement is 4 over 4 and diameter of the rollers are 28.5 mm. For this reason three drafting zones have been formed, they are front, middle and back zone. Here the roving hank has been used is 0.80 and this roving is used for producing 26 Ne and 32 Ne cotton carded yarn. By using the same roving hand and changing the gauge distances, itâ€™s easily identified which gauge distance is suitable for producing roving as well as the quality of ring yarn.Â Â

Fibers are the main raw materials in the textile industry. Now-a-days various types of fibers are available around the world but all fibers are not textile fibers. Because for being textile fibers, the fibers must have some particular physical and chemical properties. The length of natu-ral fiber plays an important role both in the spinning process and product quality. In this work, it is highlighted about a long staple natural fiber which is called jute fiber. In the 19th century, jute fiber was called the *Golden Fiber* of Bangladesh. After that this fiber lost its name and fame for the cause of our negligence and lack of knowledge. It is very difficult to know about jute because a few people were working on it. Though it’s a long fiber but there are some problems with its fixed length because this fiber consists of a large number of ultimate cells whose length is 1.5 to 4 millimeters and these cells are attached by lignin which is known as natural cement. A long fiber which is 5 to 10 feet forms after attaching these ultimate cells. During the retting period some of the lignin layers break down and long fiber length of fibers becomes shorter. Another important thing is these fibers have a mesh structure for this reason it’s difficult to identify the actual length of the fibers. That’s why fibers obtained after retting are passed through jute carding machines. The main function of the jute carding machine is to split up and break down the mesh structure. After carding, it’s quite easy to measure the length of splited jute fibers. There are not any suit-able machines for measuring the length of jute fibers. Previously people use the scale for measuring the jute fibers' length manually, through this it is so difficult to measure the length of the long fibers accurately. Here an instrument has been designed with Arduino UNO, Ultrason-ic distance sensor, Image-j software, C-programming and fabricated for measuring the fibers' length easily and accurately as well as this instrument can measure the number of fibers in that particular length. By using this instrument anyone can easily measure the length of the fibers and the number of fibers within a short possible time efficiently.
