Published: June 2021

Hormonal induction of spotted sand bass Paralabrax maculatofasciatus, was investigated in order to induce and synchronize spawning. Three experiments were conducted using wild fish captured in the Gulf of California: 1) LHRHa (luteinizing hormone-releasing hormone analogue) induced spawning with concentrations of 25, 50, 100 µg kg-1 and saline solution, 2) Effects of LHRHa on motility and sperm density, and 3) Induction and incubation of spawns obtained using LHRHa. In experiments 2 and 3 using concentrations of 12.5, 25, 50 µg kg-1 and saline solution. In experiment 1, a higher spawning ratio was observed for the concentration of 25 µg kg-1; however, no significant differences were observed in the proportion of floating (viable) eggs. In experiment 2, significant differences (P < 0.05) were observed in duration of sperm motility and sperm density, with highest duration registered for wild fish (control group) and highest density registered for laboratory control group and concentration of 12.5 µg kg-1. In experiment 3, significant differences (P < 0.05) were observed between treatments in volume of spawned eggs and proportion of fertilized eggs, with higher values shown for the concentrations of 50 and 12.5 µg kg-1, respectively. Survival at hatching and proportion of live yolk-sac larvae were significantly higher (P < 0.05) for the concentration of 12.5 µg kg-1. LHRHa was effective in inducing and synchronizing the spawning of spotted sand bass, a process which will be used for massive egg production.

Published: June 2021

Nous avons eu le privilège de traverser un grand nombre de saisons avec Mony Elkaïm. Une proximité personnelle et professionnelle intense en sol québécois, suivie de moments à distance propices à l’intégration. Étant remués par son départ et inévitablement parties prenantes de ce que nous cherchons à décrire, il demeure excessivement difficile d’isoler les apports spécifiques de Mony à l’évolution de nos pratiques. Un lien marquant, développé au fil du temps. Des rencontres empreintes de chaleur humaine, de curiosité et de mutualité. À la suite de son décès, dans le contexte si particulier des adieux interdits 1 et grâce à la bienveillante initiative des Cahiers Critiques, nous avons transformé nos rencontres d’écriture en un rituel de mémoires partagées. Dans cet article, nous racontons d’abord des petites histoires inédites qui ont touché chacun des membres de notre fratrie professionnelle. Puis, nous cherchons ensemble à identifier quelques apports spécifiques à l’évolution de notre compréhension clinique et de nos pratiques.
De la thérapie systémique à l’Incarnation rédemptrice. L’approche novatrice de Mony Elkaïm
Authors: Ide Pascal
Published: June 2021

L’article présente les innovations introduites par Mony Elkaïm (ME) dans une perspective philosophique à partir de trois notions : la pluralité, la nouveauté et le paradoxe. Pour cela, il compare l’approche systémique inédite de ME à l’approche classique individualiste et à l’approche systémique classique. En définitive, ME cherche à conjurer la violence latente du thérapeute en l’incluant dans l’acte thérapeutique, jusqu’à se donner, voire à se substituer (Levinas, christianisme).
La dette publique est-elle un problème ?
Authors: Geerolf François , Jacquet Pierre
Published: June 2021

Les inquiétudes souvent avancées sur la dette publique reposent sur nombre d’idées reçues. Le ratio de dette sur PIB est une mesure peu signifiante, et la dette publique absorbe l’épargne privée en excès. Le déficit public ne nuit pas au financement de l’investissement privé et n’est pas un fardeau pour les générations futures. Mais la dette publique doit être gérée sérieusement, mise au service de projets permettant de satisfaire les besoins et objectifs sociétaux, dès lors que l’épargne privée ne les finance pas.

La fiche à l’école maternelle : un objet littératié paradoxal
Authors: Richard-Bossez Ariane
Published: June 2021

Cet article s’intéresse au rôle que les fiches jouent dans la construction des savoirs à l’école maternelle et aux différenciations que ces supports peuvent produire, en se basant sur une enquête de terrain réalisée dans six classes de grande section socialement contrastées. Il détaille trois dimensions relatives à l’utilisation des fiches dans les classes d’école maternelle qui, en se conjuguant, participent aux différenciations cognitives dans la construction des savoirs des élèves. Il montre, tout d’abord, que les fiches ne sont pas des supports neutres dans la mesure où elles s’appuient sur un mode d’apprentissage spécifique et où elles contribuent à façonner les savoirs eux-mêmes. Ensuite, il présente les différents registres d’interprétation à partir desquels les élèves se saisissent des fiches, en insistant sur le fait que seule une minorité d’élèves s’appuie sur un registre littératié correspondant aux attentes scolaires. Enfin, il souligne comment la dimension matérielle des fiches tend à renforcer les approches les moins littératiées des savoirs. Cet article amène ainsi à mieux comprendre comment les fiches ne permettent pas aux élèves d’intégrer la dimension littératiée s’ils ne la maîtrisent pas antérieurement et comment le rapport aux savoirs et la matérialité propres à ces supports pédagogiques contribuent, au contraire, à renforcer les registres les plus éloignés des attentes scolaires.
Les activités de transfert de technologie des universités influencent-elles les performances locales d’innovation ? Le cas de l’Italie
Authors: Ciucci Laura
Published: June 2021

Ce travail étudie les effets que les activités de transfert de technologie (TT) des universités peuvent avoir sur les performances locales d’innovation. Pour ce faire, le modèle des doubles différences en panel a été appliqué à l’échelle des provinces italiennes (NUTS3) de 1999 à 2012. Les résultats suggèrent que la présence d’une université ayant établi une stratégie de TT stimule les performances d’innovation locales. L’amplitude de cet effet varie en fonction de la qualité de la recherche effectuée par l’université. Enfin, nous nous intéressons aux conditions dans lesquelles l’institutionnalisation du TT, à travers la création d’une structure ad hoc, peut avoir un effet marginal significatif. Des tests d’endogénéité et d’autocorrélation spatiale confirment la robustesse des résultats.Classification JEL : O34, C23, R11.
Adoption d’innovations et productivité des entreprises en Afrique subsaharienne francophone : cas du Cameroun, de la Côte d’Ivoire et du Sénégal

Published: June 2021

L’objectif de ce travail est de mettre en évidence l’impact de l’adoption d’innovations sur la productivité des entreprises, en insistant sur l’adoption simultanée d’innovations technologiques et d’innovations non technologiques. Ce travail utilise une méthodologie constituée de deux blocs d’équations à structure récurrente, appliquée aux microdonnées de 1897 entreprises du Cameroun, de la Côte d’Ivoire et du Sénégal. En estimant ces équations par la méthode Probit bivariée et les doubles moindres carrés, l’étude trouve que les innovations technologique et non technologique sont complémentaires et ont des effets importants sur la productivité des entreprises. Cette complémentarité est une preuve que l’innovation technologique contribue plus à la productivité lorsqu’elle est accompagnée par l’innovation non technologique et vice versa. L’introduction de nouveaux produits (ou services), accompagnée par de nouvelles méthodes d’organisation et de commercialisation, a un effet plus important sur la productivité des entreprises.Classification JEL : Q55, O55, P12, J24, D24, O14.

Authors: Mandviwala Dilshad Kersi , Agrawal Vineet Suresh , Kapoor Sonali Vinod
Published: June 2021

Introduction:

The aim of this in vitro study is to evaluate and compare the root-end cavities for the presence of microcracks after cavity preparation using two different ultrasonic (US) retrotips and conventional bur.

Materials and Method:

Thirty single-rooted teeth were instrumented and obturated. Three millimeters of apices were resected. Retrograde Class I cavities 3 mm deep were prepared on resected surfaces of ten teeth with diamond-coated US retrotip (Group 1), ten teeth with zirconium-nitride-coated US retrotip (Group 2), and ten teeth with conventional bur (Group 3). The root-end surfaces were examined under a stereomicroscope and the resected root surfaces were evaluated for the presence of microcracks on microphotographs.

Results:

Statistically significant difference was detected between diamond-coated and zirconium-nitride-coated US retrotips and also significant difference was detected when the same were compared with conventional bur for the presence of microcracks.

Conclusion:

Within the limitations of the study, it can be concluded that both zirconium-nitride- and diamond-coated retrotips produce more dentinal crack formation compared to conventional bur, but none of them produce a complete crack. Moreover, the diamond-coated retrotips produce less debris formation and minimal dentinal crack compared to zirconium-nitride-coated retrotips.

Published: June 2021

There has been a paradigm shift in the treatment options available to an endodontist. A lot of clinical, as well as laboratory studies, have been published over the last few decades. Often a clinician faces a problem in deciding a treatment plan for a particular clinical problem. Systematic reviews (SRs) and meta-analysis (MA) can help to find reliable data for a specific research question. In simple words, the SR and MA are research on all existing literature on a specific research question. The purpose of this article is to provide a step-by-step procedure for conducting SRs and MA.

Authors: Mannaa Fathia A. , Abdel-Wahhab Khaled G. , Hassan Laila K. , Taher Rehab F. , Morsy Fatma A. , Fadl Nevein N.
Published: June 2021

Background and objective

Thyroid disease represents the most common endocrine abnormality in recent years. This study was conducted to evaluate the effect of Melissa officinalis methanolic extract (MME) on hyperthyroidism in a rat model.

Materials and methods

Hyperthyroidism was induced by daily subcutaneous injection of L-thyroxine (250 μm/kg body weight) for 14 days. Total phenolic compounds in extract and the in-vitro antioxidant activity of extract were determined. Moreover, identification of methanolic extract component of Melissa officinalis leaves (MME) was done using liquid chromatography–mass spectrometry. After 30 days of MME treatments, blood samples were collected for further biochemical determinations. Liver and kidney were excised for the determination of oxidative stress markers. Thyroid gland was also removed for histopathological examination.

Results

Various thyroid hormones (total and free triiodothyronine, as well as total and free thyroxine) were seriously affected and increased significantly with hyperthyroidism induction. Significant increases in serum glucose, interleukin-6, and interleukin-8 were detected in hyperthyroid group compared with control values, whereas hemoglobin level has not changed. Compared with control group, hyperthyroidism-induced glutathione depletion and reduction in glutathione peroxidase activity in the liver and kidney tissues, with significant increase in the lipid peroxidation and nitric oxide levels. Upon treatment with MME, significant improvements in thyroid hormones and the other aforementioned parameters were achieved. MME succeeded also in ameliorating the histological picture of the thyroid gland.

Conclusions

Current results indicate that MME treatment counteracts the oxidative stress induced by L-thyroxine and protects the liver and kidney and regulates blood glucose in hyperthyroidism state. We suggest that MME treatment may be considered for therapeutic use for hyperthyroidism.
Trends and issues in community mental health programs in India
Authors: Giri Deepak Kumar , Chaudhury Suprakash , Chakraborty Prashanta Kumar
Published: June 2021

Psychiatric disorders are among the leading causes of disability the world over. With the World Health Organization, spearheading the crusade to incorporate the mental health component into primary health care, developing countries also have accepted the need for community care of patients with psychiatric disorders. Since independence various initiatives by the government has led to a significant change in the place of mental health care as part of the general health care. At the time of independence apart from mental hospitals, there was practically no organized mental health care. Since then General Hospital Psychiatry units and also Psychiatric Nursing homes have started. Currently, mental health issues are actively seen as part of the public agenda in the various forms. The overall effect has been the movement to recognize mental health as an important issue in the community and services to move beyond mental hospital care to care to the community. Majority of population in Jharkhand is residing in rural areas. Due to the lack of proper communications and infrastructure, Ranchi Institute of Neuropsychiatry and Allied Sciences (RINPAS) had started community outreach program way back in 1999. At present, these centers are running in four different areas of the state with great success. RINPAS experience shows that how even with resource constraints, quality services can be provided to unreached population.

Authors: Krishnaprabhu Rajkumar , Shadamarshan R Arunkumar , Roy Chowdhury Sanjay Kumar
Published: June 2021

Context:

Several materials have been used for maxillary sinus augmentation for subsequent implant-supported prosthetic rehabilitation. No perfect material has been identified for the purpose.

Aims:

The aim of the study is to clinically and radiographically evaluate the use of Sterile Demineralized bone matrix (Osseograft™) for maxillary sinus augmentation and subsequent implant-supported prosthetic rehabilitation.

Subject and Methods:

Sinus augmentation and implant placement were carried out in twenty patients with Osseograft™. Using intraoral periapical radiographs, radiographic implant length (rIL), residual bone height at the mesial (mRBH) and residual bone height at the distal (dRBH) aspects of the implant, and height of the graft apically (aGH) were measured. Residual bone height (RBH) = Mean of mRBH and dRBH, implant penetration (IP) =difference between rIL and RBH, Extent of the sinus lift (SL) = sum of IP and aGH were calculated and a qualitative assessment of maturation was performed using the Sinus Grafting Remodeling Index (SGRI).

Statistical Analysis Used:

Descriptive statistics.

Results:

The mean residual bone height immediately after surgery was 6.81 mm. The mean IP length was 5.45 mm. The mean aGH was 3.21 mm. The mean extent of the SL was 8.89 mm. At 3 months and 6 months, the mean aGH was 2.68 mm and 2.57 mm. The mean SL at 3 months and 6 months was 7.84 mm and 7.73 mm. The SGRI was 1 in all cases immediately postsurgery; between 1 and 2 at the end of 3 months; 2 in 15 cases and 1 in 4 cases at the end of 6 months.

Conclusion:

Osseograft™ can be used as an effective material for sinus augmentation with minimal complications and morbidity to the patient.
Randomize clinical trial of the effect of machined and rough surface of implant collar on crestal bone level and surrounding soft tissue
Authors: Chugh Anshul , Rani Sunita , Gupta Ambika
Published: June 2021

Statement of Problem:

The importance of implant collar/neck in crestal bone area triggered the need to understand the influence of its design/surface topography on surrounding hard and soft tissues.

Purpose:

This study analyzed the effect of machined and rough surface of implant collar on bone level at crestal region and surrounding soft tissues in maxillary and mandibular anterior region.

Materials and Methods:

The clinical study was conducted on 20 participants (15 males and 5 females) based on the inclusion and exclusion parameters. Participants were broadly divided into two groups with 10 dental implants in Group R (implant with rough collar design) and Group M (implant with machined collar design). The participants were evaluated at baseline (within 1 week after implant placement), 3 months, and 6 months for crestal bone level and soft tissue parameters (pink esthetic score [PES]).

Results:

All implants showed clinically acceptable bone loss at interval of 6 months, i.e., 0.68 and 0.74 on mesial and distal aspect of R group implants, respectively, and 1.15 and 0.83 at mesial and distal aspect of R group implants, respectively. And also, the PES of all implants observed was above the clinical acceptability level, i.e., 6.15 and 6.05 for R and M groups implants, respectively.

Conclusion:

It can be concluded from the present study that there is no significant difference statistically in bone level at crestal region and soft tissues parameters in two different implant collar designs used in the study although the loss of bone observed was higher in machined group in comparison to rough group of implants and the PES observed was also more in R group in comparison to M group.
Evaluation of stress distribution in maxillary anterior bone from three different tapered implant thread designs with two angulated abutments
Authors: Attargekar Vikas , Galagali Girish , Reddy E Srinivas , Nidawani Prakash , Harsha R H , Naik Satyanarayana
Published: June 2021

Background:

Tapered implants imitate the natural form of the root. They are known to enhance primary stability by providing pressure on the cortical bone of regions with poor bone qualities and also has a good survival rate as it directs stresses away from the crestal cortical bone while transferring it to the cancellous bone.

Purpose:

Maxillary anatomic constraints sometimes make it necessary to surgically position implants at angles that are not optimal for prosthetic restorations or by positioning the implant in the area with the greatest available bone, with the intention of correcting the implant alignment at the time of prosthetic restoration. This is made possible, in carefully planned cases with the use of angulated abutments.

Materials and Methods:

Three tapered implants with triangular, square, and buttress thread designs having a 15° and 25° angulated abutment were created. The implant models were positioned in anterior maxillary bone D2 and D3 and clinical loading conditions simulated. The maximum equivalent von Mises stress values were recorded and analyzed using ANSYS software.

Results:

The finite element analysis carried out showed less stresses from tapered implant square thread design in D2 and D3 bone with 15° angulated abutment, while buttress thread design performed better in D2 and D3 bone with 25° abutment angulation on axial and nonaxial loading.

Conclusion:

Bone type is an important factor that affects stress distribution. More stress occurred in D3 bone compared to D2 bone type. Thus, bone type should be carefully considered when choosing the most appropriate implant design.

Published: June 2021

Background:

Chyawanprash is a classical Ayurveda polyherbal formulation that has proven immunomodulatory potential.

Aim:

The present clinical study was conducted to evaluate Chyawanprash for prophylaxis of COVID-19 infection.

Materials & Methods:

It was an Open-label, Multicentric, Randomized, Comparative, Prospective, and Interventional Community-based Clinical Study. The study was conducted at five sites across Maharashtra, Gujarat, and Rajasthan between May 2020 and November 2020.

Materials and Methods:

A total of 771 subjects were screened in the study; of whom, 721 subjects were randomized into two groups. Subjects in the DCP group who fell into the category of 13 years to 70 years were given Chyawanprash as a study intervention to be taken in a dose of one teaspoonful (approx. 12g) twice daily and children aged 5 to 12 years were given ½ teaspoonful (approx. 6g) twice daily followed by a cup of milk (approx. 200mL). Subjects in the control group were advised to consume one cup of milk (approx. 200mL) twice daily. The incidence of COVID-19 was assessed by reverse transcription polymerase chain reaction (RT-PCR)/antigen testing, which was conducted as per applicable guidelines and the severity of infection was assessed by using the World Health Organization (WHO) ordinal scale. The incidence and severity of non-COVID-19 infections was also assessed during the intervention period of 90 days.

Results:

Overall, 696 subjects completed the study, of whom 351 subjects were in the Chyawanprash (DCP) group and 345 were in the control group. In the DCP group, out of the 351 subjects who had completed the study, 42 were tested with RT-PCR/antigen and one subject was found to be positive for COVID-19. In the control group, out of the 345 subjects, 28 were tested with RT-PCR/Antigen and eight subjects were found to be positive for COVD-19. In the DCP group, the incidence was statistically significant lesser as compared with the control group. A total of 43 subjects in the control group and 41 subjects in the DCP group had symptoms of Influenza Like Illness (ILI). The DCP group also showed a statistically significant improvement in quality of life (QoL), as assessed by the Quality of Life Enjoyment and Satisfaction Questionnaire – Short Form (Q-LES-Q-SF) when compared with the control group.

Conclusion:

The outcome of the present study suggests and supports the prophylaxis potential of Chyawanprash as one of the preventive remedies for COVID-19 as recommended by the AYUSH fraternity. The beneficial effects may be due to the synergistic effects of the potent herbs that are known to have immune-boosting effects in healthy individuals.
Quercetin-3-O-β-D-glucuronide Inhibits Mitochondria Pathway-mediated Platelet Apoptosis via the Phosphatidylinositol-3-kinase/AKT Pathway in Immunological Bone Marrow Failure
Authors: Xia Le-Min , Zhang Ai-Ping , Zheng Qin , Ding Jie , Jin Zhe , Yu Hai , Wong Wan-Hui , Yu He-Ping
Published: June 2021

Objective:

Quercetin-3-O-β-D-glucuronide (QG) can alleviate immunological bone marrow failure (BMF) by increasing platelet counts. However, the principal mechanism is less known. This study aimed at deciphering the possible underlying mechanism of QG that is indicated in thrombocytopenic purpura.

Methods:

In vitro and in vivo experiments were carried out for investigating the mechanism behind QG-facilitated inhibition of mitochondrial pathway-mediated excessive apoptosis of platelets through the phosphatidylinositol-3-kinase (PI3K)/AKT pathway.

Results:

Our results revealed that QG, the main effective ingredient of Herba Sarcandrae, increases the number of platelets and decreases the expression of Bax, Bad, Bid, and caspase-9 in immunological BMF, indicating the inhibition of mitochondrial pathway-mediated apoptosis. Moreover, we found that the protein and mRNA expressions, as well as the phosphorylated levels of PI3K and AKT, were increased significantly by QG, suggesting the activation of the PI3K/AKT pathway. Furthermore, the inhibition of the PI3K/AKT pathway by LY294002 antagonizes the effects of QG on platelet counts and mitochondrial pathway-mediated apoptosis.

Conclusion:

We demonstrate that QG inhibits the mitochondria pathway-mediated platelet apoptosis via the PI3K/AKT pathway in immunological BMF. This study thus sheds light on exploring the possible regulatory mechanism of traditional Chinese medicine in the treatment of thrombocytopenia induced by BMF.
Effects of cooling on the reproductive performance of gilts
Authors: Oyedeji J.O. , Imagbenikaro G.O.
Published: June 2021

The study examined the effect of cooling on the reproductive performance of gilts using 27 Large White Experimental Gilts on a Completely Randomized Design (CRD) with 3 systems of cooling, namely Wallow Cooling (WC), Sprinkler Cooling (SC) and Zero Cooling (ZC). Gilts were weighed at the commencement of the experiment and thereafter fed ad libitum from service to farrowing. Feed intake till farrow, feed cost, gilt weight at farrow, date of farrow, litter size and weight were recorded. The feed/piglet weight, feed intake/litter, feed cost/litter and birth weight/piglet were derived. The results showed that feed intake per litter and feed per piglet weight were highest for gilts placed on WC(P< 0.05), followed by SC and least for sow placed on ZC; gilt weight before farrow was highest for sow placed on SC (69.78±0.92), followed by ZC (69.33±0.94) and least for gilts placed on WC (67.33±0.87); litter sizes of gilts placed under the WC and SC systems were similar (5.6±0.41) while that under the ZC system was comparatively smaller (5.4±0.40);while the date of farrow was lowest in the ZC system (113.8±0.32) followed by SC (114.0±0.33) and highest under the WC (114.1±0.33). However, the feed intake per litter, feed per piglet weight, litter sizes of gilts, birth weight per piglet of gilts and the average date of farrow among gilts placed on WC, SC and ZC were not statistically different at 5% level of significance. Though, there is no significant difference in the performance among gilts placed on WC, SC and ZC, temperature regulation through provision of efficient cooling system in piggery would help to increase litter size, improve feed intake per litter and reduce the average cost of feeding gilt per day in maximizing reproductive performances in pigs.Keywords: Cooling, gilts, service, farrow, piggery, litter size, piglet and birth weight

Is Edward Abramowski an ethicist of care? Part II. The comparison of the ethics of care and the ethics of friendship

These two papers contribute to the research tendency that seeks an analogy between the ethics of care and other ethical theories. The purpose of this study is to compare the ethics of care with Edward Abramowski’s moral theory. The critical appraisal of both theories requires the reconstruction and confrontation of issues such as friendship‑brotherhood‑care, response to the needs of others, and making friendship‑brotherhood‑care public. The analysis of philosophical sources was carried out with the use of tools from hermeneutics and the history of ideas. In the case of the ethics of care, both the theories of direct caring relations and of group, institutional caring relations were examined. The analysis of Abramowski’s philosophy is focused on the ethics of friendship. In Part I, the ethics of care and the ethics of friendship are presented. Part II refers the results obtained from the analysis of the ethics of friendship to the theses and arguments which feature in the ethics of care.

Czy Edward Abramowski jest etykiem troski? Część II. Porównanie etyki troski i etyki przyjaźni

Seria dwóch artykułów wpisuje się w tendencję badawczą poszukującą analogii pomiędzy etyką troski a innymi teoriami etycznymi. Celem pracy jest porównanie etyki troski i teorii moralnej Edwarda Abramowskiego. Krytyczne badanie obu teorii polega na odtworzeniu i konfrontacji rozumienia takich zagadnień, jak: przyjaźń – braterstwo – troska, źródła reakcji na potrzeby innego, upublicznienie przyjaźni – braterstwa – troski. Do jego realizacji wykorzystano analizę tekstów filozoficznych przeprowadzoną z uwzględnieniem narzędzi hermeneutyki i historii idei. W przypadku etyki troski badaniu poddano zarówno teorie bezpośrednich relacji opiekuńczych, jak i teorie relacji pośrednich, międzygrupowych, zinstytucjonalizowanych.

A Project of Changes to Civil Procedure in the Works of the Civil Reform Committee (1814–1815). A Source Edition – Part 1 (Trial)

The present source publication is the fifth in a series encompassing the most important documents related to preparations for the replacement of French codes with national codification written by the Civil Reform Committee which worked between 1814 and 1815. Herein are contained the minutes of the sessions held by the Committee which concern a key debate among its members who argued as to whether to derogate the French Code of Civil Procedure in its entirety or only in fragments which were considered to be the most burdensome in Polish realities. Moreover, the publication also includes the first part of “The project of the civil judicial procedure in first instance”(primary procedure) presented by Franciszek Grabowski, a preeminent traditionalist in the Committee, along with fragments of the minutes reporting the course of the discussion concerning the project. Together with the second part of the proposition submitted by Grabowski encompassing enforcement proceedings, a counterproject of the code of civil procedure by progressive judge Antoni Bieńkowski, as well as a debate over these two proposals, which are to be published in the next issues of “Krakowskie Studia z Historii Państwa i Prawa”, the materials presented below portray the crux of the debate held over the Code de procedure civile of 1806, which aroused much controversy, and which was in fact the most criticized part of the French legislation in force in Polish territories.

Published: June 2021

Bu çalışmada mürdümüğün (Lathyrus sativus L.) çimlenme üzerinde alkali stresinin etkileri incelenmiştir. Bitki materyali olarak 2006, 4403 ve 1603 yerel populasyonlar ile GAP Mavisi ve İptaş çeşitleri kullanılmıştır. Çalışmada alkali çözeltisi olarak sodyum karbonatın (Na2CO3) 6 farklı konsantrasyonu (0, 10, 20, 30, 40 ve 50 mM) uygulanmıştır. Çalışma bölünmüş parseller deneme desenine göre 3 tekerrürlü olarak kurulmuş olup, her genotipden 20 tohum petri içerisine konulmuş ve petrilere 10 ml Na2CO3 solusyonu eklenmiştir. Daha sonra petriler parafilm ile sıkıca kapatılmış ve iklimlendirme odasında karanlık ortamda 20±1°C’de 7 gün boyunca çimlenmeye bırakılmıştır. Denemede çimlenme hızı, çimlenme oranı, kök boyu, sürgün boyu, kök yaş ve kök kuru ağırlığı, fide güç indeksi ve ODAP içeriği incelenmiştir. İncelenen özellikler bakımından 1603 yerel populasyonu çeşitler kadar alkali stresine iyi cevap vermiştir. Uygulanan doz oranları bakımından ise 20 mM alkali dozunda dahi bitkilerin kabul edilebilir bir çimlenme gelişimine sahip olduğu görülmüştür. Ayrıca dozların artmasıyla birlikte ODAP içeriğinin azaldığı ve tüm genotiplerde ve dozlarda hayvan sağlığını olumsuz yönde etkileyecek düzeyin altında olduğu belirlenmiştir. Buna göre,  mürdümüğün hafif alkali stresinden olumlu yönde etkilendiği belirlenmiş olup, çalışmadan elde edilene sonuçlar ileride yapılacak çalışmalara ışık tutacak niteliktedir.

Published: June 2021

Zararlı böcekler ile mücadele için yapılan biyoteknik mücadele, böcek populasyonunu olumsuz yönde etkileyen tüm ses, koku ve görsel etmenler yardımıyla, böceklerin zararını, ekonomik zarar eşiğinin altına düşürmeyi hedeflemektedir. Biyoteknik mücadele yöntemlerinden biri de böceklere karşı ses dalgalarının kullanılmasıdır. Ephestia kuehniella Zeller (Lepidoptera: Pyralidae)’nın da dâhil olduğu güveler timpanal organları ile avcı yarasaların çıkardıkları 20-200 kHz frekanstaki sesleri algılarlar. Uçuş sırasında ultrasonik ses algılayan bir pyralid güvesi hemen ani bir manevrayla ses kaynağından uzaklaşır veya kendini yere atarak hareketsiz kalmaktadır. Pyralid güvelerinin bu davranışından yola çıkarak, laboratuvar ortamında kurulan bir tercih testi düzeneğinde, 40-50 kHz (21 farklı frekans) arasındaki ultrasonik sesler sinüs ve kare dalga şekilleri ile E. kuehniella üzerinde 50 cm mesafeden uygulandı. Güvenin ultrasonik seslere maruz kaldığı zaman hareketsiz kalma veya kaçış davranışı incelendi. Araştırmanın sonucunda tercih tüneline bırakılan E. kuehniella’nın, hem ses verilmeyen kontrol uygulamasında hem de uygulanan bütün frekans ve dalga şekillerine karşı hareketsiz kaldığı tespit edildi.

Bu araştırmada, Gökçe, Arda ve Yerli nohut (Cicer arietinum L.) çeşitlerine büyükbaş ve küçükbaş hayvan gübresi, katı solucan gübresi ve NP uygulamalarının bazı bitkisel ve tarımsal özelliklere etkisi araştırılmıştır. Deneme tesadüf parselleri deneme desenine göre tam çiçeklenme, bakla bağlama ve tam olgunluk dönemlerinde hasat edilmek üzere her bir dönem için üç tekrarlamalı olarak düzenlenmiştir. Gübre uygulamaları ekimle birlikte yapılmıştır. Bitkilerin tam çiçeklenme, bakla ve bağlama dönemlerinde bitki boyu, kök uzunluğu, nodül kuru ağırlığı, yaprak alanı, yaprak sayısı, yaprak kuru ağırlığı ölçümleri için örnekler alınmıştır. Tam olgunluk döneminde bitki boyu, bitkide bakla sayısı ve ağırlığı, bitkide tane sayısı ve bitki tane verimi ölçümleri yapılmıştır. Gübre uygulamalarının incelenen özellikler üzerine etkisi incelenen gelişme dönemlerinde önemli bulunmuştur. Tam çiçeklenme döneminde NP gübrelemesi bitki boyu, yaprak alanı, yaprak sayısı ve yaprak kuru ağırlığını olumlu etkilemiştir. Bakla bağlama döneminde kök uzunluğu, yaprak alanı ve kuru yaprak ağırlığı üzerine küçükbaş hayvan gübresi etkili olmuştur. Nodul kuru ağırlığı tam çiçeklenme döneminde kontrol grubunda, bakla bağlama döneminde küçükbaş uygulamasında daha yüksek bulunmuştur. NP uygulamasında ise nodul oluşumu gerçekleşmemiştir. Tam olgunluk döneminde bakla sayısı, tane sayısı ve tane verimini küçükbaş hayvan gübresi daha fazla etkilemiştir.
Plant Identification Via Leaf Classification Using Color and Biometric Features
Authors: Çiğdem TURHAL
Published: June 2021

Plants that are of great importance for humans and other living things are an integral part of our ecosystem. In today's world, where many plant species are at risk of disappearance, the identification of plants helps to protect and survive all natural life. There are many studies presented in the literature for plant identification. The most popular of these identification methods is leaf based classification. The reason for choosing leaves in this classification is that they are easier to obtain than other biometric components such as flowers available for a short period of time. Various biometric properties of the leaf must be determined for leaf classifications. In traditionally it is time consuming and expensive to perform this process visually by experts. In this article, various leaf biometric features obtained by digital image processing methods are used as the feature extraction step for automatic leaf classification. As the classification algorithms, Naive Bayes, Linear Regression, Multilayer Perceptron, Decision Tree and Random Forest are used. According to the experimental results using the training set as the test set, 100% recognition rate is obtained for Random Forest classification algorithm and 96% recognition rate is obtained in 30-fold cross validation for Linear Regression classification algorithm.

Published: June 2021

This study was conducted to evaluate the effects of different drying methods (shade drying, sun drying and oven drying at 40°C) on essential oil content, composition and color quality of rosemary (Rosmarinus officinalis L.). The essential oil content was obtained by hydro-distillation of dried plants, and were analyzed by GC-MS. The results showed that different drying methods had no significant effects on essential oil content, but essential oil constituents and percentage affected by drying methods as well. Camphor, (between 27.57 and 29.15%), 1.8 cineol (between 17.62 and 9.39%), borneol (11.25-12.37%) and linalool (between 7.30 and 8.18%) were the major essential oil compounds of different drying methods. In total regarding the essential oil composition, oven drying method can be recommended as the appropriate procedure for major constituents of rosemary essential oil. In this study, Lightness (L*), greenness (a*), and yellowness (b*) of dried leaves were also evaluated. Drying methods affected the color quality of the herb.

Korelasyon analizi sonucunda; tüketici tutumu ile algılanan fayda arasında anlamlı pozitif zayıf bir ilişki, tüketici tutumu ile satın alma niyeti arasında orta seviyede anlamlı pozitif bir ilişki, algılanan fayda ile satın alma niyeti arasında orta seviyede anlamlı pozitif bir ilişki olduğu belirlenmiştir. Sonuç olarak; günümüz pazarlarında organik ürünlerle ilgili güven ve kalite arttırıcı çalışmaların yapılması son derece önem arz etmektedir.
Dealing with all types of quotations (and their parallels) in a closed corpus: The methodology of the Project The literary tradition in the third and fourth centuries CE: Grammarians, rhetoricians and sophists as sources of Graeco-Roman literature
Authors: Rodríguez-Noriega Lucía
Published: June 2021

The Project The literary tradition in the third and fourth centuries CE: Grammarians, rhetoricians and sophists as sources of Graeco-Roman literature (FFI2014-52808-C2-1-P) aims to trace and classify all types of quotations, both explicit (with or without mention of the author and/or title) and hidden, in a corpus comprising the Greek grammarians, rhetoricians and " sophists " of the third and fourth centuries CE. At the same time, we try to detect whether or not these are first-hand quotations, and if our quoting authors (28 in all) are, in turn, secondary sources for the same citations in later authors. We also study the philological (textual) aspects of the quotations in their context, and the problems of limits they sometimes pose. Finally, we are interested in the function of the quotation in the citing work. This is the first time that such a comprehensive study of this corpus is attempted. This paper explains our methodology, and how we store all these data in our electronic card-file.
QuotationFinder - Searching for Quotations and Allusions in Greek and Latin Texts and Establishing the Degree to Which a Quotation or Allusion Matches Its Source
Authors: Herren Luc
Published: June 2021

The software programs generally used with the TLG (Thesaurus Linguae Graecae)
and the CLCLT (CETEDOC Library of Christian Latin Texts) CD-ROMs are not well
suited for finding quotations and allusions. QuotationFinder uses more
sophisticated criteria as it ranks search results based on how closely they
match the source text, listing search results with literal quotations first and
loose verbal parallels last.
