Abstract: 

The present study was conducted to determine some feedstuffs nutritive values through different methods and to make a comparison between the methods. Six canulated steers (Holstein and Sistani) were taken into experiment in a completely randomized design of two observations per each replication. The amount of gas production at 0, 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours and feed degradation through nylon bag method at 0 , 4 , 8 , 16 , 24 , 48 , 72 and 96 hours were measured. The feedstuffs used included: alfalfa hay, wheat straw, corn silage, concentrate and cotton seed, fed at the maintenance level. Dry matter degradabilityat 96 hours for alfalfa hay, wheat straw and corn silage were 71.52, 51.02 and 77.89, and at 48 hours for concentrate and cotton seed were 80.59, and 53.51 percent, respectively. Dry matter effective degradability for the above feedstuffs at the maintenance level was 64.40, 36.70, 66.43, 76.03 and 48.16%, respectively. Dry matter degradability for these respective feedstuffs at 24 hours was 66.93, 33.57, 68.24, 79.83 and 48.71. The amount of gas production at 96 hour of incubation for alfalfa hay, wheat straw and corn silage were 51 , 45 and 75.5 milliliters , respectively, and for concentrate and cotton seed at 48 hour of incubation were 81 and 58.5 milliliters. Correlation coefficient between dry matter degradation and gas production for these feedstuffs were 0.99, 0.99, 0.99, 0.96 and 0.99 respectively and correlation coefficient between crude protein degradation and the amount of gas production were respectively recorded as 0.97, 0.99, 0.99, 0.99 and 0.98. Due to the high correlation coefficient existing between dry matter degradation, crude protein degradation, ADF and NDF degradation, and gas production, regression equations between these parameters and gas production were assessed for an estimation of the amount of these parameters from the amount of gas production without a need for tedious digestion experiments. As an example regression equation between alfalfa dry matter degradation and its gas production was: Y = 35.724+ 0.714x. In line with 51 milliters of gas production for alfalfa at 96 hour, this equation estimated 72.14% of degradation for alfalfa dry matter during this time, which in comparison with the 71.52% from digestion experiments, there is not any significant difference observed between the two recordings.

Abstract: 

This study was conducted to investigate the effects of infrared processing of barley for 60, 90, 120 and 150 seconds (s) on protein hydrophobicity, in vitro protein digestibility, degradation characteristics of protein and starch and its feeding effect on ruminal pH of sheep. The surface hydrophobicity of protein increased (P<0.04) as processing time increased. The degradation rate and effective rumen degradability of protein and starch decreased up to 90 s and remains constant at higher processing times (P<0.05). In vitro protein digestibility of barley increased at processing time of 60 and 90 s, remain constant at 120 s, then decreased at 150 s (P<0.05). Electrophoretic analysis showed aggregation of barley proteins that remain undegradable for longer time in the rumen. Ruminal pH of sheep fed processed barley was higher (P<0.05) than those fed untreated sample. There were no significant differences in ruminal pH of sheep fed barley processed at times over 90 s. It was concluded that infrared processing for 90 s, as shortest time, could decrease rate and extent of protein and starch degradation of barley in the rumen.

Abstract: 

The reception of Popper in Japan has not been a glorious history up to the present day. There have been numerous misunderstandings and distortions. It is important to record and discuss them in order to learn from them and to make use of his ideas in the Japanese intellectual climate. This is the purpose of the present paper. From the perspective of the reception history, we searched the reasons why Popper has been misunderstood in Japan (especially in four areas: philosophy, economics, history, and political philosophy), and tried to identify some of the factors responsible for this misunderstanding. To this end, we applied the method of “situational analysis” to the Japanese peculiar intellectual situation after the so-called après guerres, rather than by using a chronological order. If the causes of misunderstandings and distortions in Japan can be clarified by means of a situational analysis, we can learn a great deal from this history and can use this knowledge to throw new light on the status of critical rationalism in Japan

Abstract: 

A B S T R A C TThe morphology of each region is related to its landforms, the morphology of flat areas is related to inselbergs. The presence of inselbergs in desert and dry areas gives a special appearance to the morphology of these areas. The study of these landforms and the effective factors in their formation is considered a necessity in terms of regional development. According to the studies, various factors play a role in the formation of inselbergs, and the role of lithology seems to be more prominent. In this research, which was conducted with the method of field and library studies, we identified 18 inselbergs in Safi Abad plain and by studying them, we came to the conclusion that the inselbergs of this plain are mainly formed in sedimentary rocks such as limestone, conglomerate and sandstone. Among the geological formations, the largest and most diverse inselbergs in the Safiabad plain are formed in the mass conglomerate formation with good hardening because this formation is the most widespread in this plain. But the most typical inselbergs of this plain are formed in thick layered limestone. Because this formation is more resistant to erosion. Lar Formations including Limestone and Thick Limestone’s to Mass Dolomite and Delichai Formations have also played an important role in the formation of inselbergs in this plain. Although the extent of these formations is not significant, but due to their significant resistance to erosion and being far from these processes, they have caused the formation of evolved inselbergs in this plainExtended AbstractIntroductionInselbergs are ridges with a height of less than 500 meters formed with a steep slope in the plains. Their resistance to erosion has caused them to be considered capable players in the morphology of arid and semi-arid regions. Due to their uniqueness in desert areas, these areas are of interest to tourists, and the economic situation of these areas can be improved by attracting tourists. The prominence of inselbergs in desert areas has caused researchers to pay attention to their studies, the most important of which are the studies of Pye in Kenya (1984), Nenonen in Finland (2018), Luiza in Brazil (2021), Laetitia in Africa (2019), and Mashaal in Egypt (2020). Although the conditions for inselberg formation are available in some areas of Iran, and these landforms have given a particular face to the morphology of this country, no significant study has been done on them so far. This research attempts to investigate the role of lithology in inselberg formation in Safi Abad Plain by using library and field studies. MethodologySafi Abad plain in the northeast of Iran and North Khorasan province and in terms of geographical coordinates between 36-˚ 48-05 to 36-22-55˚ North and 37-57˚ East to 36-˚ 37-08 It is located at 57-58-11 east. Field and library studies were used to study the inselbergs of this plain. The entire region was surveyed in 2 years in the field studies, and 18 inselbergs were identified. Then, the location and extent of their expansion were determined. In the morphometry that was done as a survey, the minimum height, length-to-width ratio of inselbergs, and their distance from each other were measured with GPS. The study of the concepts, definitions, and effective processes in inselberg formation was done with the library method. The maps of this research were drawn with Adobe Illustrator software. Results and discussionInselbergs are diverse in terms of morphology; in the studied area, 18 inselbergs were identified, most of which are mixed. Most of them are rocky and have less vegetation. Regarding lithology, inselbergs are particular forms of igneous and metamorphic rocks, but some are also formed in other rocks. Although lithology plays an essential role in inselberg morphology, it cannot be claimed that inselbergs formed in the same formation have the same shape. Although the dominant lithology of the Safi Abad plain is formed from sedimentary rocks, due to the different resistance of its formations, the height, shape, and slope of the inselbergs of this plain are different in different parts of the region. The difference in these characteristics has caused the different shapes of the land in this plain. According to the studies of the most resistant formations of Safi Abad plain against erosion, limestone is a thick layer of chert mass formed due to the resistance against the erosion of the complete inselbergs.After this formation, the Lar formation consists of fine-grained uniform dolomitic limestone with thick to massive layering, which is more resistant; that is why many inselbergs in the region have formed in it. The third formation in terms of resistance is the Apsin-Albin unit, which includes orbitolinate limestone and thick limes to a mass of dolomite. Although this unit has a small area, its inselbergs are closer to typical inselbergs. In terms of area, most of the area is composed of mass conglomerates with good hardening. Due to the different effects of this formation from different processes, its inselbergs do not have the same morphology. The inselbergs formed in this formation are in the middle part of the high area, low in the southern part, incomplete in the western part, and incomplete mushrooms in the path of the Gerati River. After this formation, gray shales are the most resistant to erosion. This formation, which belongs to the Jurassic period, has formed a large part of the northeastern inselbergs. The alternation of limestone and marl in the Delichai formations in the middle part of the region provides the basis for the formation of mushroom-shaped inselbergs in the future. ConclusionSafiabad Plain is in the northeast of Iran, and in terms of geomorphological units, it is part of central Iran. Inselbergs form part of the morphology of this plain. In this study, 18 inselbergs were identified in this plain, and their detailed study showed that their primary skeleton was established by tectonic activities in the Devonian to Miocene period with the formation of Posht Bahram mountains. It was formed when the tectonic activities calmed down and in opposition to the lithology and erosion of the inselbergs of this plain. In terms of lithology, the well-hardened conglomerate formation covers nearly 47% of this plain, and due to its large size and different distances from erosion processes, various inselbergs have been formed in it. The southern inselbergs formed in this formation have a regular shape due to wind and blue erosion. In contrast, the middle inselbergs have an incomplete shape due to the distance from higher erosion, and the western inselbergs have an incomplete shape due to the superiority of blue erosion. Another formation that plays a vital role in this field is Lar Mei Formation. Although this is the second formation in terms of size and strength, many inselbergs have formed in it. The Shemshak formation is placed after the Lar formation in terms of resistance. This formation has caused the formation of chain inselbergs in the northeast of the region. The most typical inselbergs of the region are observed in the thick layered limestones of the formation (Maastrichtian). Also, this research found that inselbergs may be formed in all flat areas of the world and even in sedimentary formations. However, the inselbergs formed are far from those formed in tropical regions' igneous and metamorphic formations. FundingThere is no funding support. Authors’ ContributionThe authors contributed equally to the conceptualization and writing of the article.

Abstract: 

Background: In a Mass Casualty Incident (MCI), when medical resources are overwhelmed by the number and severity of casualties, victims’,triage plays a crucial role in disaster management. This study aimed to assess the difference between two triage methods, Simple Triage and Rapid Treatment (START) and the Sacco Triage Method (STM), in an MCI scenario and determine which way leads to a more accurate and quicker triage. Methods: This simulated cohort study was conducted in the Department of emergency medicine at AJA university of medical sciences, Tehran, Iran, from April 2021 until January 2022. In this simulated prospective cohort study, observers were selected among 2nd-year medical students and newly graduated paramedics and presented with an imaginary disaster scenario. Half of the medical students and paramedics used the START method, and the other half prioritized patients with STM. The triage accuracy, time to triage, and time to evacuation in the two methods were recorded and analyzed. Results: One-hundred-fifty observers were divided into four groups. All of them were male, and their mean age was 20. 37±, 1. 22 years. The overall accuracy for STM was 89. 52% which showed a better and statistically significant performance than the START method (p<0. 001). The mean time to triage for each patient in START and STM was 14. 29+-2. 95 and 16. 84+-3. 33 seconds, respectively. The mean time to evacuation for each triage method was 4. 76+-. 98 minutes for START and 5. 61+-1. 11 minutes for STM. In both STM and START groups, medical students performed better in triage than paramedics (p<0. 001 for START and p=0. 025 for STM). Medical students were also significantly faster than paramedics in the time to triage and evacuation categories in the STM group (p<0. 001). Conclusion: In conclusion, 2nd-year medical students and newly graduated paramedics performed a more accurate and quicker triage with STM than the START method.

Abstract: 

To investigate the effect of weed interference and weed-free periods on Balangu (Lallemantia royleana Benth. in Wall) and to evaluate the critical period of weed control (CPWC) in this oilseed crop, an experiment was conducted as a randomized complete block design with three replications in Naghadeh region in 2018. Experimental consisted of two groups of treatments; weed infestation treatments (infestation for 144.2, 345.9, 574, 848.2, 1147.6 and 1451.3 growing degree day (GDD) after transplanting and then plots were remained weed-free the rest of the growing season) and weed-free treatments (weeding for 144.2, 345.9, 574, 848.2, 1147.6 and 1451.3 GDD after transplanting and then plots were remained infested until harvesting time). In each block, one weed free and weed infested control was for all the growing season. Results indicated that the density and dry biomass of weeds were increased as weed removal was delayed. In contrast, density and dry biomass of weeds were decreased as weeds establishment was delayed. Height, tetrachenes fruits, ripened achenes, 1000-seed weight and biological, seed and relative yields of Balangu were decreased and increased as the duration of weed-infested and weed-free period increased, respectively. Also, logistic and Gompertz curves fitted to data showed that the beginning and end of the CPWC based on a 10% yield loss of relative yield, was estimated to be from 11 to 108 days after transplanting (97 days weed-free period) in order to prevent a noticeable yield loss.

Abstract: 

Notwithstanding Karl Popper’s deep admiration for ancient Greece and his affection for modern Greece, his work has been mostly viewed with caution by Greek scholars who, until relatively recently, often chose to either ignore or downplay it. This stance can be partially attributed to the novel approach of Popper’s critique to Plato which did not fare well with the foundational biases of modern Greek academic tradition and the prevailing intellectual inclinations of Greek scholars in the fields of the methodology of science and political theory. Although this bias has begun to recede during the last decades, there remains a lot to be done to fully integrate Popper’s work into the Greek intellectual and social discourse. Nevertheless, the establishment of the Department of History and Philosophy of Science at Athens University, along with the efforts of academics and public intellectuals, particularly during the Greek financial crisis of the last decade, have played a pivotal role in generating a broader interest in critical rationalism and popularizing Popper’s ideas among a wider audience. This paper examines the evolution of the reception of Popper’s ideas in Greece, both in scholarly circles and in public life, from the time of publication of his seminal work “The Open Society and its Enemies” until today, highlighting the efforts to foster a more comprehensive understanding of his important contributions
