Authors: Khabarova D. F. , Spiridonov E. K.
Published: September 2022

The operational process of a piston pump with dampeners which valves are replaced by hydraulic semiconductors is researched. The calculation model for the complex stream flow in the pump flow-part under harmonic motion of a piston is proposed. Dependences of flow characteristic and pump efficiency are derived. The influence of pump parameters on its characteristics is analyzed. It is found that an increase of the piston relative square and diodicity causes flow characteristic boost. Valveless pump efficiency mainly depends on diodicity, diodicity increase causes efficiency boost.

The World Health Organization, has declared the recent multiregional outbreak of monkeypox, a global public health emergency. Monkeypox is a zoonotic viral infection endemic to the west and central Africa. It belongs to the Poxviridae family, the Chordopoxvirinae subfamily, and the Orthopoxvirus genus. The Poxviridae family generally consists of complex, large, enveloped, and linear double-stranded DNA viruses. The initial clinical symptoms of monkeypox are often fever, severe headache, lymphadenopathy, myalgia, and fatigue. The skin lesions typically erupt within 1–3 days of the onset of fever. The rash tends to be more localized on the face and extremities than on the trunk. Monkeypox is often a self-limiting infection, and symptoms last from 2 to 4 weeks. It is isolated from various species, but the exact natural host is uncertain. Monkeypox is transmitted by close contact with infected humans or animals. Currently, no specific medication is available for monkeypox, and the existing therapeutics are the anti-viral agents approved for smallpox infection, including tecovirimat, cidofovir, and brincidofovir. Additionally, the U.S. Food and Drug Administration has approved Vaccinia Immune Globulin Intravenous for treating vaccination complications. It is diagnosed by PCR. There are currently two vaccines licensed by the U.S. Food and Drug Administration. According to the WHO guidance, the first-generation smallpox vaccines held in national reserves of some countries are not recommended as they do not meet the current safety and manufacturing standards. The interim guidance indicates that new and safer (second- and third generation) vaccines for smallpox, may be beneficial for monkeypox prevention, including JYNNEOS, which has been approved for the prevention of monkeypox. Human monkeypox was first reported in 1970. Since then, it has caused several outbreaks, mainly in central and west Africa. The first monkeypox outbreak outside of Africa occurred in the United States in 2003, linked to contact with infected pet prairie dogs. More recently (2018-2021), monkeypox cases have been reported in travelers from Nigeria to the United Kingdom, Israel, Singapore, and the US. Since May 2022, multiple monkeypox cases have been confirmed in several non-endemic countries, raising the concern of an emerging global pandemic. This review is an updated overview of our current state of knowledge regarding monkeypox virology, pathophysiology, clinical characteristics, epidemiology, vaccines, diagnosis, and treatment options.

Published: September 2022

Objective: Diabetes mellitus (DM) is known as the silent pandemic. It is hypothesized that other endocrine systems are affected by the metabolic changes occurring due to DM. We aimed to investigate the correlation of thyroid hormones with glycaemic and lipid parameters.
Materials and Methods: 81 diabetic patients and 81 non-diabetic age and sex-matched healthy volunteers participated in the study. Their blood samples were analysed for fasting blood glucose (FBG), glycosylated haemoglobin (HbA1C), total tri-iodothyronine (T3), total thyroxine (T4), free T3 (FT3), free T4 (FT4), thyroid-stimulating hormone (TSH), total cholesterol (CHOL), High-Density-Lipoprotein cholesterol (HDLC) and Low-Density-Lipoprotein cholesterol (LDLC). Data was analysed using appropriate statistical tests.
Results: Among the cases, 70.37% were euthyroid, while 24.7% had subclinical hypothyroidism, 2.47% had clinical hypothyroidism, 1.23% had subclinical and 1.23% had clinical hyperthyroidism. FBG, HbA1c and TSH (P< 0.05) were significantly higher in diabetics compared to controls. On the other hand, T3, FT3, FT4, and HDLC (P< 0.05) were significantly lower in diabetics compared to controls. A significant negative correlation (P< 0.05) was found when T3 and FT3 were compared against age, FBG and HbA1c. A significant positive correlation (P< 0.05) was found when T3 and FT3 were compared against HDLC, LDLC & CHOL.
Conclusion: Our statistics show that high-normal levels of T3 and FT3 are correlated with lower levels of FBG and HbA1c, hence improved glycaemic control. We recommend that thyroid profile of diabetic patients with poor control should be monitored regularly. Early detection of thyroid dysfunction and initiation of therapy for it, can improve the treatment outcome of hypoglycaemic drugs.

The objective was to evaluate the maturation time to obtain oocytes in Metaphase
II (MII) stages and the rate of division and blastocysts after fertilization in alpacas.
For this, the ovaries were obtained from benefited animals. Experiment 1: 441 oocytes
were distributed in four times (26, 32, 38 and 42 hours) and matured in TCM-199. At the
end of the maturation time, the oocytes were fixed in an ethanol solution: acetic acid
(3:1) and stained with aceto-orcein (1%). Experiment 2: 959 oocytes were cultured under
the same conditions as experiment 1 and fertilized with sperm obtained by artificial
vagina and selected by the Swim Up method. At the end of the fertilization time, the
presumed zygotes were cultured in SOFaa medium for 7 days. In experiment 1, 39.6 ± 8.0,
49.1 ± 18.6, 45.9 ± 9.1 and 38.2 ± 9.9% of oocytes were obtained in Metaphase-II for 26,
32, 38 and 42 h of maturation, respectively, without statistical difference (p>0.05).
In experiment 2, the cleavage rate was 45.7 ± 3.5, 51.3 ± 10.2, 52.8 ± 5.6 and 50.9 ±
3.1 with no statistical difference between treatments (P>0.05) and the blastocyst
rate was 20.5 ± 3.4, 30.5 ± 5.8, 21.2 ± 2.5 and 22.8 ± 3.5 for 26, 32, 38 and 42 hours,
respectively, with a statistical difference between 32 hours and 26, 38 and 42 hours
(p<0.05). The results obtained suggest that 32 hours of maturation are required to
obtain 30.5% of blastocysts

Seminal plasma proteins (SPP) are fundamental for oocyte fertilization by sperm
cells. In bovine, the structure and function of SPP have been widely described in
several studies, where the spermadhesin family has been highlighted. Spermadhesin
proteins are closely related to sperm motility and viability along with protecting the
sperm cells against oxidative stress. Spermadhesin-1, also known as acidic Seminal Fluid
Proteins (aSFP), exhibits a redox activity that protects the sperm cells from reactive
oxygen species (ROS), an important feature that could be taken in advantage to improve
the postthaw seminal quality of sperm cells after cryopreservation processes. Therefore,
the aim of this research was to produce heterologous aSFP using Escherichia coli as a
cell factory. For this purpose, the DNA sequence of aSFP was inserted into a pDAss
plasmid, containing a six-histidine tag (6xhis). The obtained construct was used to
transform BL21 (DE3) E. coli competent cells. The expression trials were developed at
three different temperatures (37°,25°, and 16°C) and two different concentrations of
Isopropyl-β-D-1-thiogalactopiranoside (IPTG) as the expression inductor (0.5 y 1.0 mM).
The aSFP-H6 produced was purified by affinity chromatography, and the peptide sequence
was verified through mass spectrometry. Results evidenced the best conditions for the
recombinant aSFP-H6 production (16°C and 1.0 mM of IPTG). In this sense, the viability
and the conditions to produce heterologous bovine aSFP were described and could be
further used to enhance cryopreservation bovine sperm mediums.

The feeding program carried out during the pre-partum and post-partum period in
dairy cows is crucial to preserve their reproductive performance. The goal of the
present study was to assess the effect of black wattle (Acacia mearnsii) supplementation
on ovarian activity, uterine involution, and hormone profiles in dairy cows maintained
at high-altitude conditions. A total of 10 Holstein dairy cows were divided into 2
groups: control (C; n=5) and supplemented group (AM; n=5). A dehydrated black wattle
(AM; Acacia mearnsii) supplement was administered to AM group and adjusted to 22% crude
protein per animal (Dehydrated Supplement; MS= 2.7 kg AM/day per cow, ~20% of total DM).
Body weight (BW) was recorded individually in different periods (day 15 pre-partum, and
day 19, 34, and 49 post-partum). Ovarian [follicles (FL), corpora lutea (CL)] and
ovarian diameter (OD; mm)] and uterine structures [uterine horn thickness (HT; mm),
cervix length (CrL; cm) and diameter (CD; cm), and uterine involution %] were assessed
till day 34 postpartum. Moreover, hormone profiles such as thyroid-stimulating hormone
(TSH; IU/mL), follicle-stimulating hormone (FSH; IU/mL), luteinizing hormone (LH;
IU/mL), and progesterone (P4; ng/mL) were measured till day 49. Statistical differences
were observed in BW when day 15 prepartum was compared to day 19 postpartum (p=0.05).
However, no differences were observed between C and AM group regarding BW within each
timepoint (p>0.05). No changes were observed in FL over time irrespective of the
group studied (p<0.05). However, FL was significantly different when C and AM group
were compared within each time-point (p< 0.05). Although no significant differences
were observed on day 5 post- partum regarding the number of CL, significant differences
were observed on day 25 and day 34 postpartum between groups (p> 0.05). OD increased
from day 5 to Day 35 post-partum irrespective of the group assessed and differ between
groups within time-points (p< 0.05). Differences were observed in TSH within day 19
and day 49 post-partum (p< 0.05). FSH was statistically different between groups on
day 19 post-partum (p< 0.05). LH was more variable than TSH and FSH among and within
time-points and groups (p< 0.05). Differences were observed between groups regarding
P4 within day 19 and 49 post-partum (p< 0.05). In conclusion, overall although no
differences were observed in BW between groups or time-points, the supplementation with
AM showed differential patterns in reproductive tract structures/dimensions and hormone
levels in dairy cows maintained at high-altitude conditions

For years, researchers have been seeking to manipulate sex before conception.
Although the use of sexed semen has been of great interest in the past 20 years to
inseminate dairy heifers, the massive use of sexed semen was somewhat limited because
fertility was compromised and could not be solved by increasing the number of sperm per
inseminating dose. However, new simplified and less traumatic procedures for sperm have
recently been developed that have significantly improved pregnancy rates obtained with
sexed semen. However, for the massive use of this technology it is necessary to develop
fixed-time Artificial Insemination (FTAI) programs for sexed semen. Therefore, a series
of experiments were carried out on heifers in cows with calf on foot. In all cases the
animals were synchronized with the help of paint at the base of the tail to detect the
presentation of jealousy and optimize the IATF schedules. Although pregnancy rates were
generally higher for conventional semen than for sexed semen, pregnancy rates with sexed
semen were 45 to 50%. Therefore, the results of the experiments carried out show that
IATF protocols can be adapted for the use of sexed semen and thus enable the massive use
of this technology.

This document is about gene editing mechanisms in animals to enhance certain
specific characters in subsequent generations. Gene generation by gene editing is the
current revolution in biology. Today it is possible to edit the genome using the
CRISPR-Cas tool that allows you to cut and paste very precise DNA sequences like never

Published: September 2022

The primary objective of implementing embryo transfer in meat operations is to
accelerate the rate of genetic progress in the herd. Among the main factors that affect
the use of these technologies are related to the nutrition, the management and the
synchronization of the estrus. As a result of research conducted in the last 20 years,
the use of the receptor has increased through the application of protocols that
synchronize ovulation and allow the transfer of embryos without the need for oestrus
detection, generally known as fixed-time embryo transfer. (FTET). Although these
protocols have functioned well for several years, attention has recently been directed
to the effect of estrus expression and estradiol concentrations during pre-ovulatory
follicle growth on embryonic growth and pregnancy. The experiments reviewed in this
document demonstrate that oestrus expression is positively associated with high
pregnancy rates and reduced pregnancy losses in recipients receiving frozen / thawed
bovine embryos produced in vitro and in vivo.

Authors: Ermis Sıtkı
Published: September 2022

Background: Rapid detection of seed germination will be a valuable tool for seed testing laboratories and commercial seed companies. The EC test has been accepted into ISTA rules for beans. The potential of the electrical conductivity test (EC) readings in predicting total and normal germination of nine white coated and nine coloured coated French bean cultivar seeds was examined. Methods: Nine different white coated and nine coloured coated French bean (Phaseolus vulgaris L.) cultivars were obtained from different sources. EC measurements for predicting germination were carried out 2, 4, 6 and 8 h during soaking at 20°C. Germination test was conducted on three replicates of 50 seeds in between wet towel papers for 8 days at 25°C in the dark. Result: Regression models were developed between EC and percentages of normal and abnormal seedlings in the germination test. EC readings at 2, 4, 6 and 8 hours were negatively related to percentage of total (R2=0.717, 0.830 P less than 0.05) and normal germination percentages (R2=0.762, 0.897 P less than 0.05). Results suggested that EC measurements carried out in between 2 and 8 hours soaking can be used for the estimation of seed germination in beans.

Published: September 2022

Poprzeczne zespolenie podatkowe umożliwia gminom optymalizację podatkową w podatku dochodowym od osób prawnych. Polega ono na możliwości połączenia dwóch lub więcej jednostek w jednej strukturze, przybierającej formę publicznoprawną (na przykład zakładu własnego) czy prywatnoprawną (na przykład spółki z ograniczoną odpowiedzialnością czy spółki akcyjnej z większościowym udziałem gminy). Jest to zespolenie w ścisłym znaczeniu. Połączenie jednostek organizacyjnych gminy w formę koncernu jest określane jako zespolenie podatkowe w szerokim znaczeniu. W jednej strukturze zespalane są wówczas jednostki organizacyjne dochodowe i deficytowe, a ich połączone wyniki finansowe dają podstawę opodatkowania. W taki sposób gminy mają możliwość utrzymywania świadczenia deficytowych usług materialnych. Obniżenie wynikających z zastosowania zespolenia obciążeń podatkowych umożliwia też finansowanie innych usług komunalnych.
Reglamentacja jako instrument polityki gospodarczej państwa — rozważania na gruncie polityki turystycznej w czasach pandemii
Authors: Marak Katarzyna
Published: September 2022

Turystyka należy do głównych sektorów gospodarki na świecie i w Europie. Niestety była to jedna z branż najbardziej dotkniętych skutkami kryzysu wywołanego epidemią wirusa SARS-CoV-2. W publikacji przedstawiono problematykę polityki turystycznej państwa, zwłaszcza jej modeli oraz instrumentów, wśród których poczesne miejsce zajmują instrumenty prawne i administracyjne z reglamentacją na czele, jak również wpływ pandemii na politykę turystyczną. Podjęto także próbę określenia modelu roli państwa w gospodarce turystycznej w czasach pandemii. W podsumowaniu pojawia się konkluzja, że model polityki turystycznej ma charakter mieszany, który w systemie gospodarczym Unii Europejskiej określany jest jako deregulacja. Dodatkowe ustalenia prowadzą do wniosku, że w czasie kryzysu wywołanego pandemią widoczne jest odchodzenie od liberalizmu w kierunku interwencjonizmu gospodarczego i wykorzystywania wszelkich dostępnych instrumentów, a więc o charakterze zarówno ekonomicznym, jak i administracyjno-prawnym.

A GLOBAL VIEW ON DEMOGRAPHIC PRESSURE AND LABOUR MARKET PARTICIPATION
Authors: Peeters Marga , Groot Loek
Published: September 2022

Demographic change exerts pressure on labour markets and public finances across the globe. Most studies on ageing focus on the projected development of the old age dependency ratio, the ratio of persons 65 or older relative to the working age population. This ratio gives a very incomplete picture of the (fiscal) pressure from demographic changes. In this study, besides the share of the dependent population composed of the young and old we include the share of the working age population that is not active on the labour market, labelled as the labour market space. By analysing 21 developing and 29 developed economies across the globe, we cover 75% of the 9.3 billion people that the United Nations projects for the whole world in 2050. A new indicator, relating demographic pressure from fiscal spending to the available space at the labour market, enables us to quantify and compare the pressure-to-space across countries over the time span 2010-2050. The indicator points out that Poland, Turkey and Greece are most under pressure, whereas developing countries Uganda, the Democratic Republic of Congo and Tanzania will experience a very low pressure up to 2050. Across countries, the relation between fiscal pressure exerted by the dependent population and the labour market space is positive. There is thus room for using this space by, for instance, working more hours or increasing the retirement age, as this will alleviate the fiscal pressure. This suggests a policy trade-off between maintaining publicly financed services to the dependent population and maintaining labour market space.

India is a vast country occupying 2.4% of the world surface area of 135.79 million sq km.but supporting and sustaining 16.7% of the world population .There has been a constant increase in Indiaâ€™s population which reached 1028 million at the dawn of the 21st century from 238.4 million at the turn of the 20th century. India is also a predominantly rural country .As per the census (2001) which was undertaken during Feb 19 to 28, 2001 with a provisional round from March 1 to 5, 2001, share of Indiaâ€™s rural population stands to 72.2 per cent out of 1028 million .In order to utilize the full potential of any country, proper engagement of its people is a precondition. However owing to several factors like male dominance,purdah system, weak infrastructure, customs and traditions, religions instructions etc.,energies and potential of a vast chunk of population i.e. women has remained unutilized and underutilized.

Plains-wanderers Pedionomus torquatus are Critically Endangered grassland birds that are rarely observed in arid New South Wales (NSW). In autumn 2022, however, this species was twice observed at Fowlers Gap Arid Zone Research Station in the north-west of the state. These observations occurred following significant summer rains in habitat dominated by bare ground, low Sclerolaena species and sparse Curly Mitchell Grass Astrebla lappacea tussocks. Since the late 1980s, there have been only four other records from the NSW arid zone, all of which have occurred since spring 2020.
A Theoretical Calculation of the Cosmological Constant Based on a Mechanical Model of Vacuum
Authors: Wang Xiao-Song
Published: September 2022

Lord Kelvin believed that the electromagnetic aether must also generate gravity. Presently, we have no methods to determine the density of the electromagnetic aether, or we say the $\Omega(1)$ substratum. Thus, we also suppose that vacuum is filled with another kind of continuously distributed substance, which may be called the $\Omega(2)$ substratum. Based on a theorem of V. Fock on the mass tensor of a fluid, the contravariant energy-momentum tensors of the $\Omega(1)$ and $\Omega(2)$ substrata are established. Quasi-static solutions of the gravitational field equations in vacuum are obtained. Based on an assumption, relationships between the contravariant energy-momentum tensors of the $\Omega(1)$ and $\Omega(2)$ substrata and the contravariant metric tensor are obtained. Thus, the cosmological constant is calculated theoretically. The $\Omega(1)$ and $\Omega(2)$ substrata may be a possible candidate of the dark energy. According to the theory of vacuum mechanics, only those energy-momentum tensors of discrete or continuously distributed sinks in the $\Omega(0)$ substratum are permitted to act as the source terms in the generalized Einstein's equations. Thus, the zero-point energy of electromagnetic fields is not qualified for a source term in the generalized Einstein's equations. Some people believed that all kinds of energies should act as source terms in the Einstein's equations. It may be this unwarranted belief that leads to the cosmological constant problem. The mass density of the $\Omega(1)$ and $\Omega(2)$ substrata is equivalent to that of around $3$ protons contained in a box with a volume of $1$ cubic metre.
Lipofuscin as the Main Driving Force of Current Age-Related Disease: Justification and Strategies for Removal
Authors: Renteln Michael
Published: September 2022

Lipofuscin is indigestible garbage that accumulates in the autophagic vesicles and cytosol of post-mitotic cells with age. Drs. Brunk and Terman postulated that lipofuscin accumulation is the main or at least a major driving factor in aging. They even posited that the evolution of memory is the reason why we get lipofuscin at all, as stable synaptic connections must be maintained over time, meaning that the somas of neurons must also remain in the same locale. In other words, they cannot dilute out their garbage over time through cell division. Mechanistically, their position certainly makes sense given that rendering a large percentage of a post-mitotic cell’s lysosomes useless must almost certainly negatively affect that cell and the surrounding microenvironment. Here, I explore the possibility that the accumulation of lipofuscin to some extent underlies all other categories of age-related damage as defined by Dr. Aubrey de Grey. I do not think that lipofuscin removal will reverse/prevent all forms of aging, just the major component facing us currently. It may suffice for the next few hundred years by itself. In this piece, I will review what is known about lipofuscin accumulation from evolutionary and mechanistic standpoints and discuss ways of removing it from post-mitotic cells (and then the body).
Some Comments on a Time Interval Only Description
Authors: Hollestelle Harmen Henricus
Published: September 2022

The time interval description is a natural way to introduce finite intervals, like finite time intervals. This approach depends on results for radiation propagation from star sources, where properties relate to a propagation surface, which is finite for every realistic event and measurement. In contrast the usual vector approach like for Newton’s laws depends on introducing an infinite coordinate system. A time interval only approach necessarily has to start from scratch. Properties for time intervals have to be defined with time intervals. Where the first parts of this paper are devoted to time interval set properties, in the discussion part these are applied to quantities and measurements within astronomy. The introduction provides a survey of results.

Authors: Kudish Avraham , Cohen Guy , Evseev Efim , Harari Marco
Published: September 2022

The Dead Sea basin is the lowest terrestrial site on the globe and is internationally recognized as a photoclimatotherapy center. Since the last century, questions raised regarding the possible presence of a unique incident ultraviolet irradiation, allowing successful treatment of psoriasis, atopic dermatitis and other dermatological diseases. Aim: Determine the characteristics of the solar ultraviolet irradiation and understand the mechanism of action of photoclimatotherapy while applying the results to clinical protocols of treatment. Methods: A meteorological station was established at the Dead Sea basin to continuously measure global, UVB and UVA irradiation. The same irradiation parameters are also being monitored continuously by a set of identical ultraviolet irradiation instruments installed on the campus of the Ben-Gurion University of the Negev, in Beer Sheva. Results: This study details the results of these long-term measurements, ae well as their correlation with the success obtained by clinicians treating psoriasis patients. Conclusions: A database of more than 25 years has enabled the medical staff to establish tailor-made protocols for sun-exposure time intervals as a function of particular month and hour of day. The availability of such information has significantly improved the results of photoclimatotherapy for psoriasis and at the same time increasing the safety of sun-exposure at the Dead Sea.

The highest distribution was male sex at 61.1%, age 1-5 years at 61.1%, and fever at 58.3%. Further research is needed to determine the risk factors for AOM that can be used as prevention.
Arthropods in Different Vegetation in Nutmeg Plantation in Aceh Province
Authors: Sayuthi Muhammad , Hasnah Hasnah
Published: September 2022

Nutmeg (Myristica fragrans Hout) is a leading commodity from Aceh Province. The high yield of nutmeg oil and its distinctive aroma makes it in demand by the world market. The production of nutmeg plants is currently decreasing due to the disturbance of nuisance organisms so that nutmeg plants get sick and die. Appropriate agro eco-management of the nutmeg system is thought to overcome these problems. Such as by conserving the diversity of arthropod communities. Information regarding the presence of arthropods in nutmeg cultivation is very limited in South Aceh District. This study investigates the abundance of arthropods in nutmeg cultivation in different vegetation to detect the causes of the decline in nutmeg production in the South Aceh district. Sampling was carried out at 2 locations with different vegetation conditions, using the determining sub-samples. Each location consisted of 200 individual nutmeg plants, and at each location, several 20 individual nutmeg plants were assigned as samples. The results showed that the total collection of arthropod populations at the location I found nine orders, namely Araneae, Coleoptera, Dermaptera, Diptera, Homoptera, Hemiptera, Hymenoptera, Isoptera, and Orthoptera. Location II found 12 orders, namely Araneae, Blattodea, Coleoptera, Dermaptera, Diptera, Embioptera, Homoptera, Hemiptera, Hymenoptera, Isoptera, Orthoptera, and Phasmatodea). The class of insects and arachnids found at these two locations is part of the Phylum Arthropoda.

According to literature review, this is the first study investigating tear production and intraocular pressure in pygoscelid penguins living in their natural habitat. This study also provides reference values for penguins kept under professional care at zoos and rehabilitation centres. This study aimed to establish normal values for standard ocular tests, including the Schirmer tear test (STT-1) and intraocular pressure test (IOP), for penguins belonging to the genus Pygoscelis (P), namely, the Adélie (Pygoscelis adeliae), gentoo (Pygoscelis papua) and chinstrap (Pygoscelis antarctica) penguins. Ophthalmic measurements were made from the Antarctic. In the left eye of each penguin, the amount of tear production (TP) was determined with the STT-1 and the IOP was measured using a Tonovet® rebound tonometer. No macroscopic findings affecting the eyelids, third eyelid, cornea or anterior eye camera were detected in the eyes of the examined penguins. The mean STT-1 and mean IOP values of 129 and 120 adult penguins were determined as 10.163 ± 4.054 mm/min and 38.852 ± 13.188 mmHg, respectively. A statistical difference at the level of p < 0.001 was determined between the islands for the mean IOP values. While no statistically significant difference was detected between the penguin species for the mean IOP values, between the locations was found to be significant (p < 0.001). Statistical differences at a level of p < 0.05 were determined for the mean TP values between the all locations and for the mean IOP values between the all locations ( p < 0.001) and only Lions Rump - Ardley I (p = 0.023). A statistical difference of p < 0.05 was detected between the chinstrap and gentoo for the mean STT-1 values. This study, which is aimed at reporting the first literature data in this field, has shown the need for further more detailed studies to elucidate the impact of different locations, daily time intervals and seasons on the STT and IOP values of penguins.
