Authors: Abdelaal Mohammad Ahmad , El-Dydamony Eman M.
Published: February 2023

Objective: To compare the efﬁcacy of Tamsulosin, Silodosin and Tadalaﬁl as a medical expulsive therapy for treatment of distal ureteral calculi. Patients and methods: Over a period of 6 months (January 2022 to June 2022) this prospective randomized study was conducted on 170 patients with distal ureteric stone ≤ 10 mm. Patients were randomly divided into three groups. Patients in group A received Tamsulosin 0.4mg, in group B received Silodosin, and in group C receive Tadalaﬁl 5 mg. Therapy was given for a maximum of 4 weeks. The rate and time of stone expulsion, the analgesic use, attacks of colic and hospital visits for pain, and adverse effects of drugs were recorded. Results: Among 170 patients who were enrolled in study, 20 were lost to follow-up (7, 8, 5 in group A, B, And C respective-ly). There was a signiﬁcant higher stone passage rate in group C than group A and B (90% vs. 70% and 76% respectively; p-value = 0.043) and shorter expulsion time in group C (8.7 ± 3.3 days) vs. group A (12.5 ± 5.2 days) and group B (11.3 ± 4.2 days) with (p-value = 0.001)(highly statistically signiﬁcant with p-value < 0.001) and increased amount of analgesics required in group A (225 ± 115.7 mg) and group B (163 ± 77.5 mg) when compared with group C (120 ± 55.3 mg). Conclusion: Tadalaﬁl is more effective than Tamsulosin and Silodosin in treatment of patients with distal ureteric stones≤ 10 mm as regard stone expulsion rate, expulsion time with decreased number of colicky episodes and side effects.

Published: February 2023

Objectives: Arterio-ureteralﬁstula (AUF) is an infrequent but potentially life-threatening condition. The aim of this study was reviewing the literature to build a ﬂow-chart useful for an early and effective diagnosis and treatment of this pathology.Materials and methods: A literature search in PubMed was con-ducted. In addition, retrieved articles were cross-referenced. Data parameters included oncologic, vascular and urological history, diagnostics, treatment, and follow up were collected using a standard template by 2 independent reviewers. Results: A total of 140 cases of AUF out of 172 available in the literature at the time of the review, were considered. All patients presented gross hematuria. Chronic indwelling ureteral catheter (CIUC); history of pelvic surgery (HPS) and history of pelvic radiotherapy (HRT) were present respectively in 81%, 62.1%and 58.6% of the sample. The most predominant location of AUF was at the common iliac artery ureteral crossing. Angiography with provocative measures had the highest diag-nostic sensitivity (50%) and endovascular treatment with stent-graft placement across the ﬁstula is the current state of the art treatment choice.Conclusions: Failure to diagnose can postpone a potentially life-saving targeted therapy and lead to complications. The identiﬁ-cation of the Trifecta hematuria, history of pelvic surgery (HPS) and history of pelvic radiotherapy (HPR) would allow the identi-ﬁcation of patients at high risk of AUF, who may beneﬁt from more sensitive early diagnostic investigations such as CT angiography and provocative angiography. The treatment of choice in case of AUF to date consist in endovascular prosthesis placement.

Authors: Leonardi Rosario , Vecco Francesco , Iacona Gabriele , Calarco Alessandro , Mantica Guglielmo
Published: February 2023

To the Editor, Bladder cancer (BCa) is the second most common cancer in urological clinical practice, after prostate adenocarcinoma. Usually occurs in patients between 60 and 70 years old, three times more frequently in men than women. About 75% of bladder cancer are pTa or pT1, even more frequently considering a population younger than 40 years old. Early detection is of paramount importance since allows to find tumors when they are still superficial and therefore with a better prognosis

Published: February 2023

Background: Haemolysis – one of the major limiting factors of red cell concentrate quality – must be measured as a quality-monitoring requirement. According to international quality standards, percentage haemolysis must be monitored in 1.0% of red cell concentrates produced monthly and maintained under 0.8%.Objective: This study assessed three alternative methods for determining plasma haemoglobin concentration in peripheral blood banks that lack a plasma or low haemoglobin photometer – the gold-standard method – in Sri Lanka.Methods: A standard haemolysate was prepared using an unexpired whole blood pack of normal haemoglobin concentration. A concentration series from 0.1 g/dL to 1.0 g/dL was prepared by diluting portions of standard haemolysate with saline. The alternative methods, namely visual haemoglobin colour scale, spectrophotometric calibration graph, and standard haemolysate capillary tube comparison, were designed using this concentration series and were used to test red cell concentrates received at the Quality Control Department of the National Blood Center, Sri Lanka, from February 2021 to May 2021.Results: A strong correlation was observed between the haemoglobin photometer method and the alternative methods (R = ~0.9). Based on the linear regression model, the standard haemolysate capillary tube comparison method was the best of the three alternative methods (R2 = 0.974).Conclusion: All three alternative methods are recommended for use in peripheral blood banks. The standard haemolysate capillary tube comparison method was the best model.
Periodisation of the philosophy of Islamic rationalism in the perspective of Zaki Naguib Mahmud
Authors: Supriyanto Supriyanto
Published: February 2023

In the current era of disruption, causality cannot be opposed to religion, so the independence of reason can contribute to the development of contemporary global thought in the Islamic world. This paper seeks to uncover the roots of the periodization of the philosophy of Islamic rationalism in the view of Zaki Naquib Mahmud. The primary data source is three books titled Arabiy baina Tsaqafatain, Tajdid Al-Fikr Al-Arabi, and Al-Ma’qul wa al-La Ma’qul fi Turatsina al-Fikribaik. Research data is a discourse that contains elements of religion and rationalism. The process of collecting data in this study is by studying literature and tracking various references related to the study’s focus. Data analysis techniques are carried out by the method of content analysis. Data validity using a triangulation model, by comparing data and relevant theory. The result of this study is that there are five phases of periodization of the philosophy of Islamic rationalism in the perspective of Zaki Naquib Mahmud, namely simple thinking [misykat] represented by Ali ibn Abi Talib; the lamp of reason [misbah] is characterized by the occurrence of philosophical debates about leadership and the great sin; the lamp glass [Zujajah al Misbah] is marked by the appearance of Bayt al-Ḥikmah in Baghdad; the luminous star [kaukab durriy] represented by the emergence of the Brotherhood of ash Shafa; and the endowed tree [syajarah mubarakah]. In this last phase, Zaki Naquib Mahmud positioned Ibn Rushd’s rationalism as an appropriate representation so as not to regress, even allowing for the realization of the renaissance in the Islamic world. This reflection of thought is expected to be able to inspire the millennial generation of Muslims about the importance of the philosophy of rationalism in the Islamic traditionContribution: This article contributed to the goal of HTS Theological Studies to promote transdisciplinary aspects of religious studies in the international theological arena on philosophy in literary texts.
The Tout-Monde of disaster studies
Authors: Gaillard JC
Published: February 2023

This essay expands the postcolonial agenda for future disaster studies that we suggested in conclusion of the book The Invention of Disaster. It provides some refined perspectives on how to capture the diversity and complexity of the world that we draw from the philosophy of Martinican poet and novelist Edouard Glissant. Glissant’s philosophy of creolisation and relation offers critical pathways towards pluralistic approaches to understanding what we call disaster in a world that is marked by hybridity and relationships rather than essentialism and nativism. A Tout-Monde, in Glissant’s terms, that is the combined additions of different and hybrid interpretations of disaster. Exploring the Tout-Monde of disaster studies will constitute a radical and forward-looking postcolonial agenda; radical in that it will challenge many of our scholarly assumptions, popular discourses as well as common-sense policies and practices.
Students’ perceptions of the influence of media on perpetuating xenophobia in South African universities
Authors: Mgogo Quatro , Osunkunle Oluyinka
Published: February 2023

Immigration and emigration are inevitable however, some South Africans have shown a strong dislike of those coming from other countries, in the form of xenophobia. Several studies have attributed the prevalence of xenophobia in South African communities to socio-economic, sociopolitical and scapegoating issues, with some researchers highlighting the role of the media in perpetuating xenophobia-related violence. On the other hand, xenophobia in institutions of higher learning in South Africa, which are a microcosm of society, has been under-prioritised in exploring the prevalence of xenophobia. This article aims to explore students’ perceptions on the influence of media stereotypes of foreign nationals on xenophobia-related behaviours in selected higher education institutions. In part, it aims to explore students’ perceptions on the influence of media-perpetuated stereotypes that may be attributed to possible symbolic xenophobia among university students. Therefore, this article looked at three South African universities, namely the University of Fort Hare, Alice Campus in the Eastern Cape province; the University of KwaZulu-Natal, Howard Campus in KwaZulu-Natal province; and the University of Johannesburg, Soweto Campus in Gauteng province. To achieve the aims of this study, a qualitative case study approach, based on the interpretivist design, was adopted. A nonprobability sampling method, based on purposive sampling and the snowball sampling technique, was used to select participants in this study. Data were generated through focus group discussions and analysed through thematic analysis. The findings of this article revealed that xenophobic attitudes, behaviour and perceptions were prevalent among university students. The South African print media’s perpetuated negative stereotypes and its adoption of derogatory names – amakwerekwere, amagrigamba, aliens, illegal immigrants, ‘my friend’ – to represent immigrants (especially from other African countries) were highlighted as some of the contributing factors toward ongoing xenophobic violence. As part of the recommendations of this study, the Student Representative Council (SRC) and other student communities, together with students in general, have a role to play in promoting xenophobia-free university campuses through antixenophobia campaigns.Transdisciplinarity Contribution: Most xenophobic-related studies show that media reportage has an influence on xenophobic violence in South Africa. This study therefore shifts its focus toward South African universities to investigate the prevalence of xenophobia among students and explores students’ perceptions of the influence of media in perpetuating xenophobic-related violence

Published: February 2023

Rosin is a naturally available organic material obtained especially from pine trees. It finds many usages and applications in areas like soldering, pharmaceuticals, building work, engineering field etc. In this work, an attempt has been made to study experimentally the improvement in strength of rosin at normal stove top temperature by means of combining rosin in various ratios with some important organic hardeners and chemicals of literature importance. A table top book press was fabricated for the purpose of rosin pressing using simple tools like teak wood, bolt and nuts. Experiments were conducted using commonly used kitchen gas stove, fabricated book press, rosin raw material, aluminium sulfate powder, maleic anhydride chemical, acetone, ethanol and saw dust particles for making different combination materials using rosin as the main element. Results showed that, rosin on its own without additives showed higher viscosity and brittleness. When combined with organic hardener aluminium sulfate, rosin produced an improved material with reduced brittleness, good hardness and good energy absorption. And by combining with maleic anhydride chemical, rosin produced a hard monomer with an improvement in energy absorption with better future scopes. Comparatively better material was obtained using saw dust particle reinforced rosin and chemical hardener combination. Improvement in characteristics like viscosity and energy absorbed were observed using experiments at three different temperatures. With this improvements, rosin promises to be a possible future material or material additive like filler in composites with regard to anti-plastic materials or plastic alternatives.

Published: February 2023

Tractor roll over is the most common farm-related cause of fatalities nowadays. ROPS (Roll-Overprotective Structures) are needed to prevent serious injury and death. It creates a protective zone around the operator when a rollover occurs. In India the ROPS is getting mandatory across all HP ranges except narrow track. In the present study states the customized ROPS application for configurable design such as Automated safety zone for all homologation standards, ROPS A0-D excel calculator for selection of material at concept stage and bolt calculator for selection of size. For the above applications below aspects need to consider such as Tractor weight, Rear housing mounting, Operator seat index position (SIP), Seat reference points (SRP) and all ROPS homologation standards. This ROPS application is to reduce the timeline, manual error and ensure the reliability of the modular optimal design for various platforms and variants. Nowadays it is important to perform configurable design at the concept design phase across variants/platform wise including all individual parts (both assembly & child part) so that we can optimize the varieties of material and thickness used, which will reduce the development & validation cost and shorten the time-to-market in later stages. Stochastic design optimization is then performed to reduce the weight of ROPS and ensure the robustness with reliability of the modular optimal design also in this paper. A ROPS design application is an example to demonstrate the proposed methodology by using NX10 - Automation, MathApps for bolt Calculator and ROPS A0-D excel calculator for determine the energy absorption capacity of the ROPS. Application results provide us the review and feedback on the safety and rigidity of the optimized ROPS for different platforms.

Published: February 2023

The steering knuckle is an essential component in All-Terrain Vehicle (ATV) which withstands alternating loads subjected to different conditions without affecting the vehicle performance. The main objective of the proposed work was to design and analysis the steering knuckle under static conditions to observe stress, total deformation and factor of safety for proposed materials. In this present investigation, Aluminium alloy (AA7075) was chosen as it exhibits good ductility, high strength, toughness and high resistance to withstand impact load. The prime objective of this work was processed under three different conditions like virgin AA7075, AA7075 with T6 heat treatment and AA7075 with T6 heat treatment followed by shot-peening post processed technique was completed and to attain diverse strength of the samples were tested and noted appropriate responses. The secondary objective of our proposed work, an optimum knuckle design was modeled using Solidworks. The proposed materials test values were given as input data to perform static analysis using Ansys workbench by applying constraints and loads such as steering effort, braking torque, cornering force, bumping force and longitudinal load transfer on the developed ATV knuckle design based on calculation. The responses of stress concentration, total deformation and factor of safety were obtained through static analyzed conditions. On comparing AA7075 with T6 heat treated cum shot-peened material properties are higher values and the same as input data set for analyzing the developed design, in which it shows lower deformation value and less stress concentration zone with high factor of safety because of its diverse strengthening with high impact withstand ability of the knuckle. On the whole, this proposed work provides an optimal design approach and selection of suitable post processed material of ATV steering knuckle and to improve traction, vehicle performance due to better weight reduction and long life.

Published: February 2023

The pattern of utilizing the water/diesel emulsion fuels in engines had been given great importance due to its ecological and exhaustion of petroleum reserves. This investigation displays the impact of 1,4-dioxane emulsified fuel on performance and emissions at various operating pressures. 1,4-dioxane emulsified fuel (DWSD10) was prepared with 10% 1,4-dioxane, 10% water, 0.2% surfactant and 79.8% diesel. To estimate the engine performance and emissions, the engine was operated with 180 bar, 200 bar and 220 bar operating pressures and the output was equated with diesel fuel operating on normal pressure of 200 bar. BTE of 1,4-dioxane emulsified fuel at 220 bar was higher when compare with diesel fuel. CO, HC and BSEC were lower at 220 bar on par with diesel fuel. However, NOx was increases for the higher operating pressure. Overall, except NOx, at higher injection pressure (@220 bar) the 1,4-dioxane emulsified fuel outperforms the diesel fuel in terms of emission and performance.

Published: February 2023

Stone locales together with continuous maps form a coreflective subcategory of spectral locales and perfect maps. A proof in the internal language of an elementary topos was previously given by the second-named author. This proof can be easily translated to univalent type theory using resizing axioms. In this work, we show how to achieve such a translation without resizing axioms, by working with large, locally small, and small complete frames with small bases. This turns out to be nontrivial and involves predicative reformulations of several fundamental concepts of locale theory.

One of the biggest challenges faced in Brazilian cities is proper solid waste management. The school can be an interlocutor in raising awareness by directing the teaching and learning process in order to change the individual and collective behavior of students. Thematic workshops are characterized as a pedagogical intervention in which environmental education is approached in a dynamic, interactive and creative way. The objective was to identify the perceptions that children from a municipal school in Cambé, PR, have about the solid waste theme, based on drawings made during a workshop called “Composting at school”. The workshop was conducted by 11 undergraduate students attending the Environmental Engineering course at the Federal Technological University of Paraná – accompanied by a professor coordinating the action. As teaching methods, dynamic exercises, games and conversations were used, all with the aim of integrating children and promoting a reflection on the role of each one in proper solid waste management. At the end of the activity, an evaluation questionnaire was proposed to the children, which contained the proposition of a drawing, so that they could portray what they learned and their perceptions about the solid waste theme. From a view guided by Content Analysis, the drawings were classified into three categories: a) workshop stages and dynamic exercises; b) techniques for solid waste management; and c) non-human life forms in solid waste management. The workshop was a promising environmental education strategy, as it was noted that the greater the interaction and the lighter and more pleasant the activity, the greater the learning.

Der lange Atem kolonialer Bilder: Visuelle Praktiken von (Ex-)Soldaten und ihren Familien in Südtirol/Alto Adige 1935-2015
Authors: Wurzer Markus
Published: February 2023

Kolonialismus im familiären Gedächtnis. Kolonialismus ist Teil vieler europäischer Familiengeschichten: Bis heute bewahren Familien Tagebücher, Militaria oder Beutestücke auf, die VorfahrInnen als koloniale AkteurInnen nach Hause gebracht haben. Sie bezeugen nicht nur familiäre Verstrickungen, sondern haben obendrein über Jahrzehnte hinweg kollektive Vorstellungen über die koloniale Vergangenheit geprägt. Fotografien waren daran – als vermeintlich authentische Zeugnisse – ganz wesentlich beteiligt. Über den Tod der »Erlebnisgenerationen« hinaus vermittelten sie koloniale »Erfolgsgeschichten«, wodurch Familien zu einem Hort kolonialer Geschichtsmythen, etwa der »anständigen« KolonialherrInnen, wurden. Dieses Buch nimmt die kolonialen Bildbestände von Familien in der italienischen Provinz Bozen / Bolzano in den Blick, deren (Groß-)Vätergeneration am faschistischen Kolonialkrieg gegen das Kaiserreich Abessinien (1935-1941) teilgenommen hatte. Markus Wurzer untersucht die »sozialen Leben« kolonialer Bilder, also wie und wozu diese durch Soldaten und ihre Familien (re-)produziert, gebraucht und über Generationen hinweg weitergegeben wurden.

Locating Cephalometric Landmarks with Multi-Phase Deep Learning
Authors: Nishimoto Soh
Published: February 2023

Cephalometric analysis has long been one of the most helpful approaches in evaluating cranio-maxillo-facial skeletal profile. To perform this, locating anatomical landmarks on an X-ray image is a crucial step, demanding time and expertise. An automated cephalogram analyzer, if developed, will be a great help for practitioners. Artificial intelligence, including machine learning is emerging these days. Deep learning is one of the most developing techniques in data science field. The authors attempted to enhance the accuracy of an automated landmark predicting system utilizing multi-phase deep learning and voting. To guarantee objectivity, an open-to-the-public dataset, cephalometric images accompanied with coordinate values of 19 landmarks, were used. A regressional system was developed, consisted with convolutional neural networks of three phases. First phase network was to determine approximate position of each landmark, inputting whole area of compressed original images. Five secondary networks were to narrow down the area, based on the first phase prediction. Third phase networks were trained by small areas around respective landmarks, with original resolution. Third phase prediction with voting was done inputting 81 shifted areas. Successful detection rates improved as the phase advances. Voting in third phase improved successful detection rate. In comparison with previously reported benchmarks, using the same dataset, proposed system marked better results. Within the physical limitation of memory and computation, multi-phase deep learning may be a solution to deal with large images.

One of the company's efforts is to avoid financial distress which can result in the closure of the company. The purpose of this study was to examine the effect of financial performance on financial distress. Financial distress is measured using Altman's discriminatory theory or often referred to as the Altman Z-score, while company performance consists of profitability as measured by return on assets (ROA), liquidity is measured by current ratio (CR), leverage is measured by debt to equity ratio (DER). ), and sales growth. The population of this study were 13 automotive and component companies listed on the Indonesia Stock Exchange (IDX) and 12 companies were taken as a sample because one company had incomplete data. Hypothesis testing using multiple regression analysis with a significance level of 0.05. The results showed that profitability (ROA) and liquidity (CR) had a positive and significant effect on financial distress, while leverage (DER) had a significant but negative effect on financial distress. Other results show that free cash flow and sales growth have no significant effect on financial distress.

Philosophical reflection is needed to be focused on in times where there is a sense of instability and change which could also lead to revolution from the ills of society among most nations. For example, African leaders are mostly concerned with filling their pockets despite the fact that they took an oath to office during their invitation into political seats of power by the masses. Coupled with this, is the psychological turbulence that is fundamentally visible among the masses who but cannot be swayed by the wave of change. In spite the fact that most emerging economies can still be located in the African space, the wave of globalization has had its effects on many spheres of life. The importance of philosophy is to promote peace, and harmony in all areas of life, be it socio-political or economic sphere Philosophers like Plato in VII of his republic has started that unless kings become philosopher kings, then there would not be one single iota of wisdom which is going to be applied for more stability in nation states towards development, and nation building that ensure a smooth transition from one government to another irrespective of turbulence. Based on this, the paper being a qualitative research examines philosophy and its application to global turbulence era.

Short communication: New records of sperm whale social units in the Pelagos Sanctuary, Mediterranean Sea
Authors: Ascheri Davide , Fontanesi Elena
Published: February 2023

In the Ligurian Sea, the northern part of the Western Mediterranean Sea, sperm whales (Physeter macrocephalus Linnaeus, 1758) are historically sighted as solitary individuals or loose aggregations of males, while social units are extremely occasional. On 21 August 2020, two diﬀerent social units were recorded in this area with an estimate of 21 individuals in total (12 in the ﬁrst and nine in the second). The Mediterranean sperm whale subpopulation is considered Endangered under the IUCN Red List and an understanding of its movements and social structure is lacking. These observations increase our knowledge on its conservation biology and possible threats.
Killer whales (Orcinus orca) in waters adjacent to the Chukotka Peninsula, Russia

Chukotkan hunters were employed as observers between 1990 and 2000 to document the occurrence of killer whales off the coast of the Chukotka Peninsula throughout the year. The study area was divided into three parts: the south, north and east coasts and all showed a significant negative correlation between sea-ice coverage and number of killer whales sighted (r =-0.76, -0.64 and -0.74 respectively). For all areas, the majority of whales were sighted during the summer months (June-September), but during years with late ice-destruction, whales arrived a month later than in ‘warm’ years. Killer whales were sighted three times as often per observation off the north coast than the east and twice as often when compared with the south coast and were also more likely to be part of a group off the north coast. The former was thought to be due to prey availability and the latter to increase the success of the hunt when targeting large prey species. Although the aim was not to determine abundance, a crude estimate of 56 was obtained, since this was the maximum number of killer whales ever reported independently on the same day. The data presented could be used to improve predictions of the most likely/unlikely times that killer whales are present off the Chukotka Peninsula, which would be beneficial to those conducting, for example, photoidentification surveys, or conversely seismic surveys.
Autumn space-use patterns of humpback whales (Megaptera novaeangliae) in West Greenland
Authors: Heide-Jørgensen M. P. , Laidre K. L.
Published: February 2023

Five humpback whales were tagged with satellite transmitters on their summer feeding grounds in West Greenland in August between 2002 and 2005. Tracking durations lasted between 13 and 111 days and the locations obtained from the whales provided the first insight on the autumn distribution patterns of this species in West Greenland. Whales demonstrated a consistent pattern of rapid and long-distance movements along the West Greenland coast separated by longer-term, focal area use where feeding occurred. Humpback whales in West Greenland feed on capelin (Mallotus villosus), sand eels (Ammodytes sp.), and krill and these three prey species require different foraging strategies. Generally whales showed high affinity to the coast due to shallow aggregations of capelin. However some use of offshore regions was detected, likely due to concentrations of sand eels. One whale crossed Baffin Bay to Baffin Island, an area not known to support humpback whales. The rapid movements of humpback whales between feeding sites in Greenland and Canada may be a response to variable and dynamic prey resources throughout the summer and autumn seasons.
Relative abundance and size composition of prey in the common minke whale diet in selected areas of the northeastern Atlantic during 2000-04

Published: February 2023

A total of 210 common minke whales (Balaenoptera acutorostrata) were sampled in five different areas in the northeastern Atlantic during May-June 2000-04. Analysis of forestomach contents revealed a relatively mixed diet at the population level, whereas on an individual level, each whale had fed upon mainly one species. There were significant differences in diet composition between areas and some differences between years. The importance of krill in the Barents Sea increased with latitude and krill dominated the Spitsbergen diet. Capelin dominated the diet around Bear Island and contributed considerably to the diet along the coast of northern Norway. In the latter area, herring and haddock were also a great part of the diet. The diet in the Norwegian Sea consisted of mainly mature herring, while the diet in the North Sea was dominated by sand eels and mackerel. The minke whales were found to feed on a wide range of prey sizes, apparently determined by the availability of different size classes.
How much do large whales eat?
Authors: Leaper Russell , Lavigne David
Published: February 2023

Estimates of the amount of prey consumed by cetaceans have been used in ecological models and also directly compared to human fisheries yields. Most of these estimates have been based on assumptions about energy requirements. However, the lack of direct measurements for large whales has necessitated extrapolation beyond the data points available from smaller species. A number of different parameterisations of general regressions in which energy requirements or consumption are estimated as proportional to body mass raised to some power B, were compared with estimates of Basal Metabolic Rate (BMR) from the widely used Kleiber equation. The choice of values has a large impact on estimates, which can differ by an order of magnitude, but modellers are frequently forced to make rather arbitrary decisions due to lack of data. Nevertheless, neither data nor theory appear to support values of B >0.75. Although some parameter values have obtained status through common usage, these have not always been based on actual data and estimates of consumption by whales need to reflect this uncertainty. Comparison of generalised relationships with data from other sources, including rates of filter feeding, oxygen consumption and seasonal changes in energy stores, suggest upper bounds on average daily metabolic rate of large whales. Estimates based on stomach contents also indicated average daily metabolic rates of less than four times the BMR from the Kleiber formula, but these are critically dependent on estimates of digestion time for which there appear to be little data. Estimates of stored energy suggest that large whales that migrate to seasonally productive feeding areas either have relatively low energy requirements for their size or need to meet a considerable proportion of their annual energy requirements outside of the feeding grounds.
Occurrence and distribution of cetaceans off northern Angola, 2004/05
Authors: Weir Caroline R.
Published: February 2023

The occurrence and distribution of cetacean species off northern Angola was examined using dedicated survey data and incidental sighting records. Dedicated surveys for cetaceans were carried out during two geophysical seismic surveys off northern Angola between August 2004 and September 2005. A total of 3,268hr of survey effort data were collected, resulting in 779 on-effort cetacean sightings. There were 263 sightings reported off-effort and incidentally from other platforms and sports fishermen. With 21 cetacean species confirmed, the cetacean community off northern Angola is diverse and primarily tropical in characteristic, comprising four species of baleen whale, two sperm whale species, at least two beaked whale species, and 13 species of delphinid. Humpback and sperm whales were the most frequently recorded cetaceans. The occurrence of humpback whales was significantly higher within neritic waters, and during the winter and spring months in association with seasonal occupancy of their West African breeding grounds. Sperm whales were recorded in water depths exceeding 1,000m and demonstrated significant seasonality, with peak occurrence during the summer and autumn. Atlantic spotted dolphins and common dolphins (Delphinus sp.) were the most numerous delphinids recorded, with spotted dolphins showing a significant seasonal peak during the spring and summer, and common dolphins in the winter. Other species recorded included fin whale, sei whale, Bryde’s whale, dwarf sperm whale, Cuvier’s and Mesoplodon beaked whales, killer whale, short-finned pilot whale, false killer whale, melon-headed whale, Atlantic humpback dolphin, rough-toothed dolphin, Risso’s dolphin, bottlenose dolphin, Pantropical spotted dolphin, spinner dolphin, Clymene dolphin and striped dolphin. Further research is required to document the cetacean community in Angola, particularly given the unknown threat from fishery bycatch and the increasing level of oil and gas exploration in the region.
