Aims: The purpose of this study was to determine the percentage value of spermatozoa acrosome integrity with the addition of gentamicin and sweet orange essential oil on the tris yolk extender on Simmental bull liquid semen.

Methodology: The material that was used in this research included Simmental bull fresh semen, tris yolk extender, gentamicin, and sweet orange essential oil. Tris yolk extender prepares with Tris (hydroxymethyl) aminomethane (3.32 g), citric acid (1.86 g), fructose (1.37 g), glycerol (6 ml), egg yolk (20 ml), aqua dest (100 ml). The experimental design used in the study was a nonfactorial Complete Randomized Design with five treatments and five replications. The treatments comprised the addition of sweet orange essential oil at 0%, 0.25%, 0.5%, 0.75% and 1% inclusion levels. The parameter observed was the evaluation of the percentage value of acrosome integrity before and after equilibration equilibration.

Results: The results showed that the percentage value of acrosome integrity in spermatozoa linearly increased along with the addition of sweet orange essential oil. The addition of sweet orange essential oil had a very significant effect (P <0.01) on the percentage of spermatozoa acrosome integrity in Simmental bull liquid semen. The percentage of acrosome integrity on the addition of 0% (P₀) sweet orange essential oil is 60%, the addition of 0.25% (P₁) is 64%,the addition of 0.5% (P₂) is 67%, the addition of 0.75% (P₃) is 69%, and the addition of 1% (P₄) is 73%.

Conclusion: The addition of 1% (P₄) sweet orange essential oil can increase the value of acrosome integrity on spermatozoa, which subsequently improve the quality of Simmental bull liquid semen.

The study identified and assessed flood-prone communities in the core Niger Delta region of Nigeria using GIS (Geographic Information Science). Data for the study was obtained from both primary and secondary sources. The primary data was generated from the information obtained from the respondents through the administration of the questionnaire and the use of GPS to generate coordinates for the flood-prone communities in the core Niger Delta. The population of the study comprised of people in both rural and urban communities prone or ravaged by flood in the core Niger Delta states of Bayelsa, Delta, and Rivers. Random sampling technique (using blindfold) was used in the selection of 5 flood-prone communities from each of the 3 states. Random sampling technique was also used in the selection of 50 respondents from each of the 5 selected communities spread across each of the 3 selected states. This gave a sample of 250 per state totalling 750 in the 3 selected states. Furthermore, the geographic coordinates (i.e. Northings, Eastings, and Elevation) of the identified fifteen (15) flood-prone communities were taken at specific locations across the core Niger Delta. The result shows three (3) geo-referenced maps of flood-prone communities in the core Niger Delta. Further evidence from the study revealed that the respondents’ major source of livelihood was farming occupation (34.7%) and fishing occupation (21.0%), while respondents with low socioeconomic status dominated (53.0%) in the study area which implies that in the event of a flood disaster, coping with the flood disaster becomes a challenge due to the low socioeconomic status of the residents. Finally, the findings of the study reveal that the yearly occurrence of flood in the core Niger Delta region has led to the devastation or destruction of a large expanse of land including cultivated farmlands, crop yield before the flood occurrence was average (48.2%) and high (35.1%) while crop yield after the flood was very low (50.8%) and low (33.2%). The study, therefore, recommended the development or building of resilience to reduce the devastation of flood menace across communities in the core Niger Delta area and construction of structural measures like dams, culverts, drainages, and ditches to accommodate and reduce the runoff or overflow of floodwaters which causes severe social, economic and infrastructural damages or impacts in the flood-prone communities.

Carpal Tunnel Syndrome (CTS) is one of the most common neuropathies and pregnancy is a risk factor of CTS. The frequency of CTS during pregnancy, especially that according to the gestational age, is not well determined, and here we attempted to determine it in three hospitals in Lahore, Pakistan. By the use of non-probability purposive sampling method, 286 samples of pregnant females were collected. The diagnosis of CTS was made using Phalens test and others. Phalen test was positive in 20.8, 29.6, and 45.3% during 1^st, 2^nd and 3^rd trimester, respectively. The questionnaire data indicated that CTS was present in 11.2, 37.0 and 49.5% in 1^st, 2^nd and 3^rd trimester, respectively. Swelling of the joint was observed in 31.6, 51.9 and 77.8% in 1^st, 2^nd and 3^rd trimester, respectively. The same tendency of the occurrence of CTS according to the three trimesters was observed when using nerve compression test or Tinels test.

The study examines the discrepancy of job competency on SAFE programme beneficiaries in North-Western Nigeria. A multi-stage sampling technique was adopted in selecting 285 sample sizes. Two categories of respondents were considered namely: SAFE beneficiaries (212) and employer’s (73). Primary data was collected using structured questionnaires and all the questionnaires were returned and found useful for the study. Data collected were analyzed using descriptive statistics such as percentage counts, means; standard deviation and discrepancy scores. The study revealed that majority (96%) of the SAFE beneficiaries were male, married (86%) with a mean age of about 44 years, and about 18 years of working experiences in extension services. SAFE beneficiaries had a mean of 6 persons per household with a current mean salary grade level of 12. The study revealed that job competencies identified in SAFE programme were rated ‘high important’ to extension service delivery. The study further reveals that SAFE beneficiaries were rated high in job competencies possessed as result of SAFE programme. More so, the study established a positive (0.00) discrepancy score on professionalism among the SAFE beneficiaries in the study area. The study concludes that SAFE programme had positively influenced job competencies of the agricultural extension workers. The study further recommends that there is need for more female incorporated in agricultural extension services, inclusiveness of other extension workers to key into the SAFE programme as well as the need to strengthened professionalism in the SAFE programme curricula across the participating Universities in Nigeria.

Diseases are considered one of the main factors that limit the productivity of the Eucalyptus sp. Thus, the objective was to carry out a scientometric analysis of the articles, focusing on the eleven main pathogens that affect the eucalyptus culture. For the development of this study, specialized searches were carried out on the “Web of Science” database using the scientific names of pathogens and eucalyptus as key words. In the general search, a result of 123 articles published between 2000 and 2020 was obtained, with Mycosphaerella spp., Ceratocystis fimbriata, Botryosphaeria ribis and Cylindrocladium spp., The pathogens with the highest number of published works and also citations. Regarding the citations / article, Botryosphaeria ribis (average of 68.80 citations / article), Mycosphaerella spp. (average of 34.57 citations / article) and Cylindrocladium spp. (average of 27.12 citations / article). Regarding the journals, a total of 38 journals were responsible for the published works, with nine of them concentrating 60% of the total of published articles.
