Le granite albitique à colombite-tantalite et topaze des Châtelliers (Vendée) utilisé comme pierre de taille depuis le Moyen Âge : les apports de l’étude pétrologique et minéralogique
Authors: Godard Gaston
Published: November 2023

Les matériaux de construction du donjon de Pouzauges (Vendée) sont constitués d’un granite à biotite et de cornéennes qui proviennent du massif granitique de Pouzauges, comme le démontre la richesse en baryum du feldspath alcalin du granite. Cependant, un granite blanc très particulier, riche en albite et mica blanc, renfermant des minéraux singuliers (colombite-tantalite, topaze, zinnwaldite, béryl, spessartine), a été utilisé comme pierre de taille pour les ouvertures, cheminées, coussièges et latrines. Ce granite provient des Châtelliers, situés à 9 km de Pouzauges, où de vieilles excavations sont visibles. L’observation des édifices de la région montre que ce granite fut utilisé comme pierre de taille du 12e au début du 20e siècles. Choisie pour sa faible altérabilité et ses qualités esthétiques, en particulier sa couleur ivoire, cette roche servait à la confection de pierres ouvragées pour les ouvertures, corniches et cheminées des logis et châteaux, et pour les colonnes, chapiteaux, ogives et archivoltes des églises. Pour les parements ordinaires, au contraire, on utilisait des moellons en roches locales, schistes, granite ou cornéenne. Cette étude, parmi d’autres, illustre que l’examen pétrologique des matériaux de construction peut permettre d’identifier leur provenance, en particulier lorsqu’il s’agit de roches métamorphiques ou magmatiques, à la minéralogie variée.

Published: November 2023

The present paper aimed at investigating the influence of surface treatment on the failure of porcelain coating on Ti6Al4V alloy fabricated by milling and selective laser melting (SLM). The titanium alloy surface was treated by three different ways: sandblasting, application of a layer of bonding agent and combined (sandblasting and subsequent bond layer). A coating of ultra-low fusing ceramic was fabricated on one surface of the samples. The adhesion of the porcelain to the titanium alloy was investigated by standard 3-point bending test and the failure of the coating was evaluated by optical microscopy. It was found that the type of surface treatment of the titanium alloy affects the failure mechanism of porcelain coating on its surface. In case of all samples, the fracture of the ceramics was observed to occur by a mixed adhesion-cohesion mechanism with a difference in the layer of adhesive or cohesive failures. These differences are greater for the milled alloy compared to its SLM-treated counterpart. In the milled sample, adhesive failure occurs along the metal/oxide layer interface and cohesion through the oxide layer. After sandblasting, both adhesion and cohesion fractures were observed between the oxide layer and the porcelain. In the bond-treated samples, adhesive and cohesive failures were found to occur mainly between the oxide layer and the bond. Most of the specimens treated in a combined way failed cohesively by cracking the ceramic coating. In the control and sandblasted subgroups of the SLM-processed alloy, the porcelain coating was destroyed through adhesive-cohesive route: adhesive along the metal/oxide layer interface, and cohesive through the porcelain. Ceramic fracture in the bond- and combined treated subgroups was observed to occur adhesively along the bond/porcelain interface, and cohesively through the bond and porcelain.

Published: November 2023

The effects of clay surface modified with 25-30 wt% of methyl dihydroxyethyl hydrogenated tallow ammonium (Clay-DHA) on morphology, mechanical and thermal properties of poly(lactic acid) (PLA)/propylene-ethylene copolymer (PEC)/Clay-DHA composites were investigated. The phase morphology of PLA/PEC blends showed phase separation due to weak interaction between PLA and PEC phase, and the droplet size of PEC phase increased with increasing PEC content. The addition of Clay-DHA significantly improved the compatibility between PLA and PEC phases due to PEC droplet size decreased dominantly in PLA matrix, so Clay-DHA could act as an effective compatibilizer. The tensile properties found that Young’s modulus of PLA/PEC blends decreased with increasing amount PEC while the strain at break increased. The incorporation of Clay-DHA improved Young’s modulus of the blends in a range of 10-20 wt% of PEC. The thermal properties showed that the addition of PEC and Clay-DHA had no effect on the melting temperature of PLA. The degradation temperature of PLA/PEC blends was higher than that of the PLA, so PEC could improve the thermal stability of the blends.

Recent Developments in CTE-Matched Composite Thermal Materials
Authors: Saums David L.
Published: November 2023

A surprisingly large number of engineered materials are available to the module and system packaging engineer that have been designed for a target coefficient of thermal expansion (CTE, stated both at room temperature and across a specified range of temperatures) and possessing bulk thermal conductivity values useful for device heat dissipation. There are continuing research and development programs for new forms and variations of such materials, intended to meet continuing demands for improvement on a spectrum of requirements. These requirements include higher bulk isothermal conductivity values, lower cost, lower CTE values, reduced density and weight, and, for certain types of applications, a target CTE and highly anisotropic property.

This discussion seeks to identify both existing and common materials (for comparison purposes) and new developments that are being brought to market and/or are in production today. The purpose is to add to the design engineer’s tool kit for available materials of these types. In addition, high temperature effects on selected materials are illustrated.
Investigation of Key Parameters for Syringe-printing of Nano-silver Paste
Authors: Yun He , McCluskey Patrick
Published: November 2023

Additive manufacturing (AM) techniques, also known as 3D printing, have been embedded into electronic components used for power modules as they can meet complex design requirements with less material waste and shorter lead-time. However, the corresponding manufactural considerations need to be investigated to ensure good printing quality. This paper is a parametric study of previous research [1], specifically focusing on the key parameters for the syringe-printing method that has been used to print a single-layer planar transformer winding implemented on a 10kW DC-DC power converter. A series of key parameters such as kick, trim length, feed rate, and pass spacing are defined, followed by inquiring into the printable regarding the width of a single trace and the gap/printing spacing between two traces. The results indicate that the targeted trace width and gap are subjected to certain errors, resulting in an imprecise actual print, that cannot be employed when designing a CAD model. Instead, a set of recommended values corresponding to the targeted values are acquired. Linear relations between the actual values and targeted values are obtained, which provides convenience for further design when considering using syringe-printing as an AM technique to print nano-silver traces.

Published: November 2023

An interesting case of unusual unilateral variant of palmaris longus (PL) tendon of forearm was noticed by us. We found two bellies of PL as well as their different insertions. These observations will help in understanding morphological variations of this muscle and its clinical implications. PL is a fusiform muscle in the superficial flexor group of muscles of forearm. It originates from medial epicondyle of humerus by common flexor tendon. We found PL having one origin, i.e., from medial epicondyle from common tendinous origin of flexor muscles and then it divided to form two bellies having two long tendons distally. Understanding of presence or absence or anomalies of PL is not only important for medical professionals but also for evolutionary biologists. Awareness of anatomy and variations of flexor tendons is important for health care practitioners for the correct diagnosis and management of pain, disease, and trauma of forearm and hand.

Published: November 2023

Introduction

Many grafts have been described for ACL reconstruction; however, disagreements regarding globally accepted gold standard graft choice persist. Recently, the peroneus longus tendon (PLT) Autograft has been used in the field of ACL reconstruction as an alternative autograft. This study aimed to evaluate the efficacy of the peroneus longus tendon as a graft for primary ACL reconstruction and to study its possible effects on foot and ankle function.

Patients and methods

This was a prospective study that included patients who underwent ACL reconstruction using Peroneus longus tendon autograft. Results were assessed via physical examination. Donor site morbidity of the foot and ankle was assessed using Medical American Orthopedic Foot & Ankle Society (AOFAS) score and Foot and Ankle Disability Index (FADI). Postoperative knee function was evaluated by the International Knee Documentation Committee (IKDC) and Tegner-Lysholm score.

Results

Thirty patients were included in the study with a mean age of 28 years old. Peroneus longus graft diameter was 8.5 ± 0.7 mm. There was a significant difference between pre and postoperative functional scores in IKDC and Tegner-Lysholm score. Ankle scores were excellent. The mean of AOFAS was 97.7 ± 3.1 and FADI was 98.5 ± 0.5.

Conclusion

The peroneus longus tendon is an appropriate autograft source for ACL reconstruction. Its use in primary ACL reconstruction is very encouraging with minimal donor site morbidity.

Published: November 2023

Introduction

Fracture neck of femur (FNF) represents a major public health problem worldwide. The aim of this study is to evaluate the clinical, functional outcome and rate of complications of dual mobility cup total hip arthroplasty versus bipolar hemiarthroplasty in the management of displaced fracture neck femur in elderly patients.

Methods

A prospective Randomized control study was done in a university specialized unit between January 2018 and January 2021 on 40 elderly patients had a mean age of 70.5 years (range 60-91) with displaced intracapsular FNF. 20 patients were managed by Dual Mobility Cup Total Hip Arthroplasty (DMC THA group) and 20 patients underwent Bipolar Hemiarthroplasty (BHA group) for the treatment of their femoral neck fractures with a minimum 24 months follow-up (range 24-35). Rate of dislocation postoperatively was the primary outcomes while functional outcome (Harris Hip Score), intraoperative blood loss and length of operation were the secondary outcomes.

Results

The Harris hip score (HHS) was higher in the DMC THA group and was most significant after 6 and 12 months with P value (P < 0.05). The dislocation rate was less in the DMC THA group. The BHA group demonstrated less intraoperative blood loss (P < 0.001) and a shorter length of operation (P < 0.001). However, there was no significant difference in two-year mortality with P value (P > 0.05), blood transfusion rate with P value (P = 0.471) and infection rate with P value (P = 1.000).

Conclusion

In light of our results, the use of THA DMC did not seem to increase mortality, morbidity, or complications rate like infection or bleeding but it decreases dislocation rate and increase functional outcome when compared with BHA.

Published: November 2023

“Scientific writing is a mandatory skill for most researchers, and orthoapedic surgeons are no exception. However, improvement of the writing quality could be achieved using some assistive tools. The most recent ones involve using artificial intelligence (AI), specifically ChatGPT. Although it seems appealing for improving scientific writing and assisting non-native English speakers, its usage is still not well regulated, and ethical issues were raised regarding the misuse of these tools in the scientific research and writing process. Strict regulations controlling the involvement of these tools are still needed, and their judicious and honest utilization is mainly dependent on the researchers themselves.”

Authors: Jose Anu , Dandagi Satyajit , Chour Girish V. , Bora Sushmit P. , Dharan Minu Parvathi
Published: November 2023

Background:

Mandibular fracture is the second most common fracture of facial bone, next to nasal bone. Twenty-five to forty percent of mandibular fractures involve the condyle. In the literature, there exists no consensus “gold standard” treatment for mandibular condylar fractures, and there is a continuing debate on whether condylar fractures should undergo closed or open reduction.

Materials and Method:

Twenty patients who had undergone open reduction and closed reduction treatment were included in the study. Clinically maximal interincisal opening, laterotrusive and protrusive movements, pain on mouth opening, malocclusion, chin deviation on mouth opening, facial nerve palsy, hematoma, infected implant, and bite force were evaluated after a minimum of 3 months postoperatively. Also, a postoperative CT is done to evaluate the anatomical position of fragment.

Results:

On evaluation of clinical parameters, both groups had comparable results. However, none of the patients in open reduction group had deviation of mandible from midline on mouth opening. Also, better anatomical repositioning is obtained in open reduction group.

Conclusion:

The results of this study suggest that the open reduction method is a better alternative to closed reduction in treatment of mandibular condylar fractures.

Background:

Injectable platelet-rich fibrin (i-PRF) being in liquid form keeps graft particles clumped together forming agglutinated steak of bone graft. It has been shown to contain more platelets and long-term deliverance of growth factors in comparison with platelet-rich fibrin (PRF).

Aim:

The aim of the present study was to assess regenerative potential of i-PRF and comparing it with PRF, along with demineralized freeze-dried bone allograft (DFDBA) in the treatment of intrabony alveolar defects.

Materials and Method:

Thirty defect sites in 15 patients with bilateral intrabony defects were assigned randomly into two groups (Group I (Control group)- DFDBA + PRF and Group II (Test group)-DFDBA + i-PRF). Gingival index (GI), plaque index (PI), pocket probing depth (PPD), and relative attachment level (RAL) were recorded at baseline, 3 months, and 6 months. Linear bone growth (LBG) was recorded radiographically at baseline and 6 months.

Statistical Analysis:

ANOVA test and post hoc Tukey test were used to assess intragroup comparison of clinical parameters. Paired t-test was used to assess intragroup comparison of the radiographic parameter. Unpaired t-test was used to assess intergroup variations in all the clinical as well as radiographic parameters.

Results:

Statistically significant PPD reduction (P = 0.005) and RAL gain (P = 0.003) were found in Group II than in Group I, and no significant difference was found in other parameters. Percentage LBG was higher in Group II than Group I but the difference was not statistically significant.

Conclusion:

i-PRF with DFDBA showed more favorable results as compared to PRF with DFDBA in the management of intrabony periodontal defects.

Authors: Suman Satyam , Pravalika Jakkula , Nupur Satya , Manjula Pulluru
Published: November 2023

Background:

An audit is the examination and evaluation of health-care procedures and documents to compare the quality of care provided with accepted standards. The prescribing audit study is part of an audit that monitors, evaluates, and, if necessary, recommends changes in physicians’ prescribing practices. Prescription validation is a quality improvement process that aims to improve patient care.

Methodology:

A prospective observational study was conducted in the outpatient department setting of the National Accreditation Board for Hospitals and Health-care Providers and Joint Commission International approved Super Speciality Hospitals of the Capital Territory of India. Data were collected randomly, 100 prescriptions across different department settings of Super Speciality Hospitals for 1 month in November 2022. Data were analyzed on the standard format of World Health Organization core prescribing indicators and in the form of mean and percentage.

Results:

A total of 17 parameters were accessed for the prescription audit. From the data, we can predict that in a total of (n = 100) samples of prescription audit, only 21.65% (368) cases had noncompliance, 67.59% (1149) cases had compliance, and 10.76% (183) did not apply to this parameters.

Conclusion:

According to this study, the compliance rate for prescription audit parameters is 67.59%, which should be improved by training staff regularly and holding large group meetings and internal audits. Small group meetings with experienced professionals of the organization can help in the constant maintenance of quality. It is also possible to automate the prescription creation process with software for at least the basic details. Finally, the study concludes this with the organization that needs to use its clinical pharmacy experts in the quality improvement process.
Surveillance of Health Care-associated Pseudomonas aeruginosa Infections in a Tertiary Care Teaching Hospital
Authors: Chauhan Yash , Trivedi Niyati
Published: November 2023

Background:

Among Gram-negative microorganisms, Pseudomonas aeruginosa is the most frequent causative pathogen in health care associated infection (HAI). P. aeruginosa infections are becoming more challenging to treat due to its innate as well as capacity to fast acquiring resistance to available antimicrobial agents (AMAs). There needs to be continuous surveillance to understand the sensitivity pattern as well as the clinical profile of the infections caused by P. aeruginosa.

Materials and Methods:

This was a prospective, observational, study conducted in various inpatient departments of a tertiary care hospital in India. Complete clinical and epidemiological profile of the patients, from whom P. aeruginosa was isolated as a causative organism, was recorded. Such patients were followed up daily till the outcome was achieved. The sensitivity of P. aeruginosa to various AMAs was noted. Data analysis was performed using suitable statistical tests.

Results:

P. aeruginosa was isolated from 103 clinical specimens during the study. Almost all the patients were diagnosed with HAI. With the most common being skin and soft-tissue infections. 41.75% of P. aeruginosa were multidrug resistant, with 25.24% being carbapenem resistant. The duration of hospitalization after isolation was 19.83 ± 5.79 days. Sixty-two patients were successfully treated and discharged from the hospital.

Conclusion:

A high prevalence of multidrug, especially carbapenem resistance among the P. aeruginosa isolates, has been observed, compromising the ability to choose efficacious empirical regimens, use of multiple high-end AMAs, and prolongation of hospitalization. Implementation of effective preventive and control measures along with antimicrobial stewardship strategies are urgently needed.

Authors: Long Yun , Tian Sufang , Wang Binchen , Gan Tian , Wang Jingting , Meiyan Liao
Published: November 2023

OBJECTIVE:

The objective of this study was to investigate the clinical characteristics, imaging manifestations, and prognosis of patients with acquired immunodeficiency syndrome (AIDS)-related non-Hodgkin’s lymphoma (NHL).

PATIENTS AND METHODS:

This retrospective study included 92 patients with AIDS-related NHL (ARL), who were treated at the Central South Hospital of Wuhan University between January 2005 and March 2022. Patients were divided into three groups according to their pathological type: diffuse large B-cell lymphoma (DLBCL), Burkitt lymphoma (BL), and plasmablastic lymphoma (PBL). Their clinical characteristics and imaging data were compared. In addition, some computed tomography (CT) features of the tumors were analyzed and summarized. SPSS 26.0 was used for statistical analysis. The prognostic factors were analyzed using the Kaplan–Meier method, Cox proportional risk regression model, and receiver operating characteristic curve.

RESULTS:

Among the 92 cases, 68 were DLBCL, 19 were BL, and five were PBL. BL patients had a higher risk profile than DLBCL and PBL patients. Most of the tumors had unclear borders, uneven densities on plain and enhanced CT scans, and signs of fusion and necrosis. The analyses indicated that the International Prognostic Index (IPI) score (odd ratio [OR] =15.699, 95% confidence interval [CI] =1.828–134.829, P = 0.012) and Eastern Cooperative Oncology Group (ECOG) score (OR = 28.869, 95% CI = 3.015–276.395, P = 0.004) were independent prognostic indicators of the overall survival.

CONCLUSIONS:

ARL is a heterogeneous and aggressive disease with a poor prognosis. Compared with DLBCL or PBL patients, BL patients have higher risk features. IPI and ECOG scores can effectively predict the prognosis of ARL.
Expert consensus on imaging diagnostic criteria for pulmonary tuberculosis associated with acquired immunodeficiency syndrome
Authors: Xie Ruming , Li Li , Li Hongjun
Published: November 2023

Acquired immunodeficiency syndrome (AIDS)-associated pulmonary tuberculosis is one of the most common opportunistic infections in patients with AIDS and an important cause of death. Pulmonary tuberculosis associated with AIDS occurs in patients with low immunity, and its clinical manifestations are often atypical. Therefore, diagnosis of AIDS-associated pulmonary tuberculosis is difficult, and imaging plays a vital role. To standardize examinations and improve the level of imaging diagnosis, a group of experts in infection, inflammation, radiology, tuberculosis, and statistics have come together and published imaging diagnostic criteria for AIDS-related pulmonary tuberculosis with consideration of the methodological requirements for evidence-based guidelines and standards. Patients with clinical signs and symptoms of pulmonary infection who test positive for human immunodeficiency virus need to undergo further radiographic or computed tomography examination of the chest. AIDS-related pulmonary tuberculosis is suspected when there are pulmonary lesions and/or hilar and mediastinal lymph node enlargement. An imaging diagnosis of AIDS-related pulmonary tuberculosis is based on one of the following findings: mediastinal or hilar lymphadenectasis in multiple areas, diffuse miliary nodules randomly distributed in both lungs, multi-form, multi-lobular, and multi-segmental lesions dominated by exudative lesions, or pleural effusion. Further laboratory or pathological examinations are performed in suspected patients and those with an imaging diagnosis; if one of these additional examinations is positive, the diagnosis of AIDS-related tuberculosis is confirmed.

Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) has been transformed from an innovative technique, into a viable alternative to enteral stenting and surgical gastrointestinal anastomosis for patients with gastric outlet obstruction. Even EUS-GE guided ERCP and EUS-guided gastrointestinal anastomosis for the treatment of afferent loop syndrome have been performed, giving patients more less invasive options. However, EUS-GE is still a technically challenging procedure. In order to improve EUS-GE, several techniques have been reported to improve the technical details. With EUS-GE widely performed, more data about EUS-GE’s clinical outcomes have been reported. The aim of the current review is to describe technical details updates, clinical outcomes, and adverse events of EUS-GE.

The increasing demand for electric mobility has brought about significant advancements in tyre design. This paper covers the latest developments in tyre design that cater specifically to the needs of electric vehicles (EVs). EVs have unique performance characteristics that place greater emphasis on tyre requirements like High traction, Wear resistance, Low Cavity & pattern noise, Low Rolling resistance and High load carrying capacity. Hence, the tyre manufacturers have been working relentlessly to create advanced designs that can meet these requirements.

This paper will cover various aspects of tyre design, including tyre cavity, tread patterns, sidewall design, compound & reinforcement design, and various construction techniques. The tyre cavity and tread pattern play a crucial role in the overall performance of an EV. The new tyre cavity with flat tread and adaptive tread pattern are optimized to provide low rolling resistance, pattern noise reduction and enhanced dry and wet traction. Additionally, the use of advanced materials such as high-performance functionalized polymers and high tenacity reinforcements has led to the creation of low rolling resistance, lightweight and durable tyres that can withstand high power, acceleration, and braking torque on driving wheels of EVs. Furthermore, the construction techniques of EV tyres have also seen significant improvements for durability to handle heavy battery packs. In addition, this paper also highlights various enabling technology like the use of foam technology for cavity noise reduction and Sealant technology for Extended mobility.

In conclusion, this paper showcases the recent advancements in tyre design for EVs. The advancements in tyre design have enabled tyre manufacturers to create bespoke designs that cater to the specific needs of each EV model.

Food sold in healthcare facilities and environments are underestimated as sources of exposure of customers to potential pathogens. In the current study, we investigated the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in selected food items sold in two hospitals located in Benin City, Edo State, South-South Nigeria. A total of 100 food samples were obtained from food vendors and screened by pour plate method for the presence of heterotrophic bacterial and Staphylococcus aureus. Their antibiotic sensitivity patterns were determined by disc diffusion method and the presence of toxigenic and pathogenic genes by polymerase chain reaction and gel electrophoresis. Majority of the food samples investigated harbored Staphylococcus aureus, with varying levels of antibiotics resistance pattern. Only 5 of the isolates were observed to be methicillin resistant, with only one harboring the mecA gene. The results of this study are an indication that methicillin resistant Staphylococcus aureus could be a source of contaminant in ready-to-eat food sold in hospital facilities, and effort must be taken to prevent the occurrence of diseases arising from their presence.

Biofuels have become the world’s greatest, safest, cleanest and cheapest alternative to fossil fuels. Transport sector continues to receive influx of cars and general machinery every year worldwide leading to an overwhelming use of fossil fuel. The fossil fuel sources are gradually becoming depleted. Sustainable bioethanol recovered from inexhaustible sources are constantly been used to replace fossil fuels in the transport sector. The shea nut pulp (SNP) is a cheap source of carbon, nitrogen and calcium for the production of bioethanol. This study has employed the shea nut pulp as substrate, Saccharomyces cerevisiae-the Baker’s Yeast strain-as the fermentation microbe, Alpha Amylase enzyme for hydrolysis of the substrate and supported the simultaneous fermentation process with nutrient supplements. The data were subjected to statistical analysis. Approximately 37.8 and 40.0 g/L of ethanol after 16 and 20 h, were produced from without-α-amylase and with-α-amylase treatments, respectively. Fermentation efficiencies of 58.6 and 65.0 % were observed ethanol yields for without-α-amylase and with-α-amylase, respectively when compared to the theoretical yield. This research is useful in harnessing the potentials of the shea nut pulp as industrially relevant substrate for use independently or in combination with other substrates in microbial fermentation processes for ethanol production. An assessment of the fermentation process has revealed that the SNP is a good source of bioethanol going into the future. The research therefore recommends further work on scale-up of the bioethanol production process from the shea nut pulp.

The disputed issues of higher plant taxonomy and phylogeny are greatly impacted by pollen morphology because pollen grains have clear distinctive characteristics that are typically labeled. Palynotaxonomical study of Honeybees preference plants in South-Western Nigeria were conducted between the months of May, 2019 and June 2021 using fresh polleniferous materials which were extracted through acetolysis methods. Results showed that ninety-two (92) plant species belonging to thirty-six (36) plant families of apicultural importance most visited by honeybees (Apis mellifera var. adansonii) were documented. At x100 magnification, thorough morphological studies were performed, and the results showed that pollen grains from plant species in the family Asteraceae were spinolous and spherical in shape; those from the Fabaceae sub-families Caesalpinoideae, Mimosoideae, and Papilionoideae, on the other hand, had a great deal of morphological diversity with variations in symmetry, position and distribution. Those of the families Malvaceae was echinate and Myrtaceae were colporate; syncolpate and prolate respectively. However, the variations above were generally reduced within species in the same genera. Tricolpate aperture type was observed in the genus Euphorbia; giving reason for their classification in the same genera. The genus Combretum was all heterocolpate, circular in shape and heteroporate. Sculpturing was psilate or scabrate and pollen shape class were sub-prolate, oblate-spheroidal or prolate spheroidal. Similar form and symmetry observed in all the species studied were reason for their classification into the same family. The study revealed that the flowering period for most of these honeybees’ forage plants were between the months of October to March. Identification, propagation, cultivation, conservation, and sustainable exploitation of these honeybee (Apis mellifera var. adansonii) forage and preference plants would be beneficial in potentially increasing the efficiency of apiculture and commercial cultivation in South-Western Nigeria.
