Published: October 2021

Lojistik süreçler, işletmelerin kârlılık sağlaması ve rakipleri karşısında rekabet avantajı kazanması için büyük öneme sahiptir. Büyümek ve uluslararası pazarda söz sahibi olmak isteyen işletmelerin güncel gelişmeleri takip etmesi, müşterilerin taleplerini analiz etmesi ve bu talebe en uygun şekilde cevap vermesi gerekmektedir. Dünya üzerinde hızla büyüyen ve gelecek vadeden sektörlere bakıldığında helal sektörü dikkat çekmektedir. Giderek artan Müslüman nüfusunun ihtiyaçları ve sağlıklı olması gibi nedenlerden ötürü tercih eden tüketicilerin yönelimleri helal ürünlere ve hizmetlere olan ilginin artmasını sağlamıştır. Bu ilgiyi karşılamak üzere helal endüstrisinde birçok sektör hizmet vermektedir. Helal gıdaların ham madde temininden başlayarak müşteriye ulaşıncaya kadarki tedarik zinciri süreçlerinde helalliğinin korunması ve riskli bir durumla karşılaşmaması helal lojistik hizmetleri ile sağlanmaktadır. Helal lojistik faaliyetleri gıda ürünlerinin üretim, depolama, taşıma, paketleme ve satış gibi lojistik aşamalarını kapsamaktadır. Bu çalışmada helal gıda sektörünün küresel boyutta analizi yapılarak stratejik bir öneme sahip olan helal lojistik faaliyetlerinin önemine değinilmiştir. Helal gıda ticaretinde etkili ülkeler ve bu ülkelerin lojistik stratejilerinden bahsedilmiştir. Geleneksel lojistik faaliyetleri ile helal lojistik faaliyetlerinin ayrımı yapılmıştır. Dünyadan helal lojistik uygulaması örnekleri anlatılarak Türkiye’nin durumu analiz edilmiş ve helal lojistik faaliyetlerinde gelişme gösterilmesi için önerilerde bulunulmuştur. Türkiye coğrafi konumu ve ideolojik yapısı itibariyle helal lojistik faaliyetlerinin kar elde edilerek uygulanabileceği ülkelerin başında gelmektedir. Ancak yapılan araştırmalar sonucunda Türkiye’deki işletme-lerin ve müşterilerin helal lojistik konusunda ilgisiz ve bilgisiz olduğu görülmektedir. Helal lojistik sertifikasına sahip tek işletme olduğu ve bu işletmenin de helal sertifikasını belirli nedenlerden ötürü değerlendireme-diği görülmüştür. Bu çalışma ile işletmelerin ve müşterilerin bilinçlendiril-mesi sağlanarak Türkiye’nin helal lojistik sektöründe yerini almasını sağla-mak amaçlanmaktadır.
İslamofobya Bağlamında Kıtal Ayetlerinin “Şahin” Ve “Güvercin” Yorumları
Authors: İMAMOĞLU İbrahim Hakkı
Published: October 2021

11 Eylül 2001 sonrasında literal bir olgunluğa ulaşan ve Batı’nın kendi değerler dünyasında ürettiği bir korku olan İslamofobi, Müslümanlara yapılan tüm fiili, psikolojik baskı ve entelektüel bariyer oluşturma çabası olarak tanımlanabilir. Zaman içerisinde yapılan AB topluluğundaki alan araştırmaları bu problemin güncel olarak devam ettiğini ortaya koymaktadır. Müslümanlar Batı için büyüyen yeşil bir korkudur. Mevcut korkunun hem tarihi hem de zihni boyutları vardır. Esasen kavram eski korkuların yeni ifadesidir. Hıristiyan Batı için öteki olan Müslümanlarla ilişkilerde, sonucu başarısızlık olan Endülüs tecrübesi, Batı’nın zimmî Müslümanlarla ilk imtihanıdır. Haçlı propagandalarının Batı zihin dünyasında oluşturduğu olumsuz Müslüman algısı, kendi topraklarında azınlık konumundaki Müslümanlara gösterilen İslamofobik tavırların tarihi arka planını teşkil eder. İslamofobinin başlangıçta değilse de devam eden süreçte Müslümanlarla ilgili bir korkuya dönüştüğü aşikardır. Zikrettiğim korkular ve İslam’ın tarihsel birikimin redd-i mirasta bulunulması Müslümanları -modern dönem sosyo-teolojisinde- şahinleşmeye itmiştir. Batı tipi korkuları tetikleyen ve bir fobyaya dönüştüren sâikler arasında Müslümanların epistemik yetersizliği ve sosyolojik tepkiselliğini göz ardı etmemek gerekir. Bu yetersizliklerin tebarüz ettiği alanlardan birisi kıtal ayetleridir. Kıtal ayetlerinin yorumlanmasında, modernleşme sonrası, Kur’ân’la sığ anlam ilişkisi kuran muhatabın yetersizliği ve kadim bilgi geleneğinde işletilen nesih nazariyesi iki problematik alandır. Başka bir ifadeyle Selefilik ve farklı bağlamlardaki Mekki İ’râz ayetleriyle Medenî Kıtâl ayetlerinin bir araya getirilerek -belki- diplomasiye karşılık gelebilecek ayetlerin nesh edildiğini iddia etmek İslamofobinin temel sebepleri olarak kabul edilebilir. Oysa büyük çoğunluğu Mekki olan ayetler ahlakî bir tutum iken, Kıtal ayetlerinin konusu olan savaşın devletin karar mekanizması içinde yer alan olağanüstü bir tarafı vardır. Buna rağmen kadim dönemde ulemanın böyle bir eşleşmeye gitmesi ilmi değil sosyo-politik bir durumdur. Çünkü nesih nazariyesi kadim kültürde atak durumdaki İslam’la örtüşen bir nazariyedir. Bugün İslam savunma durumundadır.İslam medeniyeti “ötekiyle” bir arada yaşama kültürünü ürettiği zengin tarihi bir tecrübeye sahiptir. Gerek kurucu dönemden tevarüs eden birçok hadis (e)ler ve kurucu metin, gerekse sonraki dönem yaşanan barış ortamı tesisi, savaşın elzem durumlarda bir enstrüman olarak kullanılması “ötekiyle” olan münasebette siyasi, kültürel, toplumsal bir hafızanın oluşmasını sağlamıştır. İslamın tarihsel birarada yaşama tecrübesi, tefsir geleneğinde kıtal ayetlerinin yorumu “güvercin” kanadını teşkil etmektedir. Buna göre kadim kültürün paradigmasını doğru çözümleyip bugün için yeni bir dil inşa etmek elzem görünmektedir.

Published: October 2021

The KV heavy tank stays among the legends of the Great Patriotic War and one of the most recognizable combat vehicles of those years. The assessment of the tank, its design features and practice of operation, in scientific, popular science literature, and journalism, is still ambiguous: from praise to denial. Historical memory of this combat vehicle is actively living its life not only on pages of the books, but also in the virtual space, in the branches of thematic Internet forums and computer games. The heavy tank of KV series was developed and put into service at the very end of 1939. A new grade of 42S armor steel was created especially for it, which was distinguished by a relatively low content of alloying elements and high adaptability for mass production. The authors seriously studied the stages of armor production and the difficulties in its creation. They show the enormous contribution of metallurgists to the creation of a combat vehicle. As a result of engineering research and the decisive contribution of metallurgy, a formidable machine was obtained, possessing thick armor (75 mm) and quite powerful armament (76.2 mm cannon). At the same time, the tank had a whole range of disadvantages that reduce the effectiveness of its combat use. The general lack of development of the design and archaic technological solutions created serious problems both in the production and in the subsequent operation of this tank. History and tradition of searching the tank allows taking a fresh look at the long glorious traditions of the national engineering school in the field of metallurgy, and its decisive contribution to the Victory in the Great Patriotic War.

The article considers results of the study of microstructure parameters effect on the impact strength in temperature range from 0 to –80  °C in 20  °C increments of Charpy samples with a sharp stress concentrator and Mesnager test pieces with a circular stress concentrator from rolled coils of low-carbon microalloyed steel with various thicknesses. The used roll products were produced in conditions of JSC “Vyksa Metallurgical Plant”. The tests were performed using optical and scanning electron microscopy. It is shown that with the same chemical composition and thermomechanical treatment modes, the metal of smaller thickness (6, 8 mm) is characterized by higher strength properties (on average, by 10 MPa for temporary resistance, by 30 MPa for yield strength) and a margin for viscous properties at negative temperatures at close values of grain score and average grain size corresponding to 10 – 11 numbers according to the State standard GOST 5639. The metal with a thickness of 12 mm has the lowest level of cold resistance, and the temperature of brittle transition is minus 50 °C. Structure of rolled products of various thicknesses has a variation in grain size. Rolled metal of smaller thicknesses have a smaller grains corresponding to number 14, rolled metal of larger thicknesses has a larger grains corresponding to number 8. By conducting electron microscopic studies using the backscattered electron method, it was found that a greater number of large-angle boundaries, which are barriers for brittle cracks propagation, are observed in the 6, 8 mm thick rolled products. The constructed orientation maps of the microstructure showed the presence of pronounced deformation texture corresponding to the orientations <110>||RD (rolling direction) and (<113>...<112>)||RD for rolled products with a thickness of 6 mm.
Influence of titanium and zirconium on structure and heat-resistance of low-carbon iron-aluminium alloys
Authors: Sheshukov O. Yu. , Kataev V. V.
Published: October 2021

The paper considers the effect of introducing ferroalloys containing titanium and zirconium on the structure and heat-resistance of low-carbon ferroalloys. Theoretically and experimentally, it has been proven that addition of 1.0 mass. % of titanium and 0.1 mass. % of zirconium to a low-carbon iron-aluminum melt containing 12 – 14 mass. % of aluminum, grinds its structure increasing temporary resistance and heat-melting. Titanium and zirconium are strong carbide-forming elements. When introduced into a low-carbon iron-aluminium alloy, they form a large number of crystallization centers, thus affecting its microstructure, allowing to get shredded and more equal grain compared to an alloy without additive. This in turn increases the strength limit of processed alloy. In addition, the use of titanium as a modifying additive in a low-carbon ferroalloy allows increasing its heatresistance, which exceeds several times the heat-resistance of famous chrome-nickel steel of 20Kh23N18 grade. As a result, a new technology for obtaining titanium and zirconium was developed based on research of the effect of their modifying additives on the structure and heat-resistance of low-carbon iron-aluminum alloys.

In modern conditions, the integration of scientific knowledge is becoming an integral part of the progress and effectiveness of scientific research. In medicine, the progress of integration is of particular importance. It develops according to the dialectical laws of evolution, reflecting its logical essence. The interdependence of the structural and functional components of the integral system of the organism lies in the fact that each component of the phenomenon acts as a condition for the other and is conditioned by it.
In 1909 in Italy, a Franciscan Monk Was the First to Discover Electromagnetic Seismic Precursors
Authors: Nardi Adriano , Piersanti Antonio , Ferrara Gabriele
Published: October 2021

We present to the international scientific community three important works by Father Maccioni adapted into English with several parts literally translated. The investigation into the existence of an electromagnetic (EM) seismic precursor was carried on in Italy in the beginning of the twentieth century and exploited the capabilities of a specifically designed coherer. For several reasons, both the work and the author are widely unknown even in Italy. We think this is likely to be the very first historical case of a study of a seismic precursor of the EM type.

Comparative study between proximal femoral nailing versus dynamic hip screw in unstable inter-trochanteric fractures of the femur in adults
Authors: Kumar Manoj , Lone Zubair A. , Bhatt M. Farooq , Basit Abdul
Published: October 2021

Background: Hip fractures are more common in elderly among them intertrochanteric fractures are most common, more than 50% fractures are unstable. The proximal femoral nailing (PFN) and dynamic hip screw (DHS) are frequently used modalities from last two decades in both stable and unstable fractures. The DHS has been shown to produce good results but complications are frequent, particularly in unstable inter-trochanteric fracture. The advantage of PFN fixation is that it provides a more biomechanically stable construct with good collapse control. The goal of this study was to compare the clinical and radiographical results of the DHS and PFN for the treatment of inter-trochanteric hip fractures as one is load bearing another is load shearing.Methods: In our study we included 70 inter-trochanteric fractures, out of which 40 were treated with DHS fixation and 30 were treated with PFN, and were followed up at regular intervals of 2 weeks, 8 weeks, 12 weeks, 6 months and annually thereafter.Results: The functional results were assessed with Harris hip score and observed 35% excellent results in DHS group and 63.3% excellent results in PFN group. We observed no statistically significant difference between two groups in view of late and early complications and time to union. We observed significantly better outcomes in PFN group for unstable inter-trochanteric fractures and in unstable fractures reduction loss was significantly lower in PFN group. We observed total duration of surgery was significantly lower in PFN group.Conclusions: We concluded that PFN may be the better fixation device for most unstable inter-trochanteric fractures.

Published: October 2021

Cardiovascular disease is one of the leading causes of mortality in haemodialysis patients. Several studies have demonstrated the relation of zinc and magnesium in cardiovascular disease. In present study we aimed to measure serum zinc and magnesium levels and correlate with the Framingham score to calculate the cardiovascular risk.

Present study was prospective, cross sectional type, conducted in chronic kidney disease patients undergoing haemodialysis.Serum magnesium, zinc, cholesterol, urea, creatinine, HDL cholesterol, systolic BP are measured and Framingham score was calculated. And zinc and magnesium values were correlated with Framingham score.

The study is conducted in 100 CKD patients undergoing hemodialysis. Out of 100 CKD patients undergoing hemodialysis, 59% had high risk,28% had intermediate risk, and 13% had low risk of developing cardiovascular disease according to their Framingham risk score. In these patients, zinc and magnesium levels were found and correlated with Framingham risk score. Out of 100 patients undergoing hemodialysis, 37 patients were hypomagnesemic, 43 patients were normomagnesemic, 20 patients were hypermagnesemic. In this, a positive correlation was found between development of hypomagnesemia and duration of hemodialysis. Magnesium level was correlated with Framingham risk score. In this hypomagnesemic patients, 67% patients have low risk, 8% have intermediate risk, 24% patients have high risk of developing heart disease. Out of 100 patients, 86 patients have normal zinc level, 14 patients have increased zinc level. Zinc levels was not altered during dialysis. These patients already have risk of developing heart disease independent of zinc level.

In our study, magnesium level of haemodialysis patients was reduced and it is associated with duration of haemodialysis. Zinc levels were not altered in the patients.

Published: October 2021

A myocardial infarction (MI), often known as a heart attack, occurs when blood supply to a region of the heart is reduced or stopped, resulting in heart muscle damage. One of the elemental mechanisms responsible for the development of myocardial infarction is oxidative stress. The study aims to assess the Oxidative stress and Troponin I levels in patients with myocardial infarction (MI) and compare them with the level of these parameters in healthy controls. An attempt has been made to find if there is any correlation between oxidative stress and Troponin I levels in patients with myocardial infarction.

The Cardiac marker Troponin I and the marker of oxidative stress malondialdehyde were estimated in 30 patients with myocardial infarction and 30 healthy individuals who acted as controls. 

A statistically significant difference was observed between Troponin I and MDA in patients with MI as compared with controls. A significant positive correlation was also observed between MDA and Troponin I levels. 

In our study there wasa significant positive correlation between oxidative stress and Troponin I. Further studies with a larger number of subjects will be needed to find if oxidative stress plays a role in the pathogenesis of myocardial infarction.

Published: October 2021

Vitamin D deficiency (VDD) and hypothyroidism have been linked in research with inconsistent outcomes. Because of the controversy surrounding these two disorders and their relatively high incidence, we undertook a case-control research comparing the prevalence of VDD in hypothyroid patients (both TPO-Ab positive and negative) to euthyroid controls.

This is a cross-sectional study with a single centre. Adults (aged 18 and above) of both sexes with primary hypothyroidism (TSH >5.1 mIU/L) were included (n = 165), as were age and sex matched euthyroid (TSH 5 mIU/ml) controls (n = 165) from the outpatients' department. Biochemical parameters like Thyroid stimulating hormone (TSH), free T4 (fT4), 25 hydroxy vitamin D (Vit D) and thyroid peroxidase antibody (TPO-Ab) were tested in both the groups.

The study involved 330 patients, with 165 (mean age 46± 15 years) having primary hypothyroidism (3 having subclinical hypothyroidism) and 165 (mean age 45± 17 years) being euthyroid controls. VDD was seen in 96 percent of hypothyroid patients compared to 90 percent in the control group. The hypothyroid group had a significantly lower mean Vitamin D level than the euthyroid group (12.03± 8.6 SD vs. 17.49± 11.89 SD [ng/ml]; P= 0.001). TPO-Ab was found in two-thirds of the hypothyroid group (110/165). The mean Vitamin D level in the TPO-Ab positive hypothyroid group was 10.4± 7.2 ng/ml, compared to 15.3± 10.3 ng/ml in the TPO-Ab negative group (P = 0.004). With increased TPO-Ab titers, there was a downward trend in Vitamin D levels. A direct association between Vitamin D levels and TPO-Ab, on the other hand, did not reveal any relevance.

Patients with hypothyroidism had considerably lower vitamin D levels than euthyroid controls. TPO-Ab positive individuals had lower vitamin D levels than TPO-Ab negative patients.

Authors: Vani K , Dolia Pragna B
Published: October 2021

In genetically diabetes-prone populations, maternal diabetes during pregnancy increases the risk of their children developing diabetes and obesity (the vicious cycle of type 2 diabetes). Fetal hyperinsulinemia at birth acts as a marker of this risk. The objective of this study is to find out whether cord blood leptin concentrations are increased in offspring of mothers with type 2 and gestational diabetes mellitus (GDM) and to evaluate gender differences if any, in their levels.

Cord Serum Leptin measured by ELISA: 1. Cord Blood from 40 babies (20M, 20F) born to GDM Mothers. 2: Cord Blood from 20 babies (9M, 11F) born to Type 2 DM Mothers. 3. Cord Blood from 30 babies (15M, 15F) born to Non Diabetic Mothers.

Babies born to mothers with both type 2 diabetes and GDM had higher birth weight. They also had higher Leptin concentrations [ng/ml] compared to Controls; Leptin concentrations in Type 2 Diabetes -Mean [42.32+24.09], in GDM – Mean [40.31+22.71] & in Control subjects – Mean [23.87+15.48]. Birth weight of the female babies were also higher than that of male babies.Leptin concentrations were not significantly higher in the female babies in comparison to the male babies.

High cord leptin, birth weight and ponderal index (kilograms per cm), in babies born to Type 2 diabetes and GDM mothers.

Authors: Anees Syyeda , Harakuni Sheetal , Kausar Ruksana
Published: October 2021

Competency based undergraduate curriculum stresses on objectivity, uniformity, validity and reliability of the assessment tools since assessment drives learning. Conventional Practical Examination (CPE) in Biochemistry is subjective and associated with examiner variability and raises concerns over its validity and reliability. Objective Structured Practical Examination(OSPE) addresses this problem as it includes objective testing through direct observation, assessment of knowledge, comprehension and skills.In this study the performance of 1 MBBS students in CPE & OSPE was compared & perception of students and faculty towards OSPE as Formative Assessment was evaluated.

  Study included total of 150 Phase 1 MBBS students of 2019-20 batch & faculty of Biochemistry were included. CPE and OSPE was conducted on topic “Estimation of Blood Glucose” and marks were awarded.OSPE was conducted with 2 procedure & 4 response stations. Statistical Analysis: Percentage graphs & Student’s’ test using MS Excel were used.

  There was statistically significant difference between the mean scores of CPE and OSPE (P < 0.01).

 Our study concludes that the scores of OSPE were better than that of CPE. OSPE eliminated examiner bias by integration of cognitive, psychomotor and affective domains. Therefore OSPE can be introduced as Formative Assessment & Summative Assessment.

To compare the efficacy of external dacryocystorhinostomy (DCR) and botulinum toxin-A in the management of functional epiphora.

A prospective, comparative, interventional study included 45 patients with functional epiphora out of which 20 patients had undergone external dacryocystorhinostomy and 25 patients received 5 units of injection botulinum toxin in the palpebral lobe of lacrimal gland as per the patient’s preference. All patients underwent syringing and fluorescein dye disappearance testing before the procedure. Epiphora was graded subjectively with Munk scores obtained before and after intervention. Duration of side effects and severity were also noted.

This study showed functional epiphora common in elderly age group. Female constitued of 71.11% and male 28.89 % with female: male ratio of 2.4:1. Left eye (42.22%) predominantly involved. The overall success rate at 6 months after surgery for external DCR was 95% and that of injection botulinum was 91.17%. The overall success rate in both the group was not statistically significant(p>0.05%). Improvement in epiphora graded by Munk score was statistically significant after intervention in both the groups(p<0.05%).

This study showed injection Botulinum toxin can be considered as an alternative management in case of functional epiphora for patient who do not want to undergo surgical intervention and for those with co-morbid conditions with high risk for surgical intervention like DCR.

Ultrasonography (B scan) has emerged as a useful technique in ocular injury scenario. We aimed to evaluate role of B Scan ultrasonography in management of ocular injuries.

All patients with ocular trauma attending the emergency department were enrolled for the study. Relevant history and demographic data was noted on the study proforma. Detailed ocular examination was done employing slit lamp biomicroscopy for anterior segment and direct and indirect ophthalmoscopy for posterior segment evaluation. All patients were necessarily subjected to B scan ultrasonography (USG) for additional clinical information.

A total of 50 cases were enrolled. The mean age of affection was 28 years. The most common mode of injury was agriculture related. The most common anterior segment finding was traumatic cataract as seen in 22(44%) cases while on USG posterior vitreous detachments seen in 36% cases, followed by retinal detachment in 24% cases and vitreous haemorrhage in 22% cases. Choroidal detachment was accurately localized in 2% cases.

The study emphasizes the need for B-scan as a valuable tool in the diagnosis of posterior segment pathologies particularly when the media has become opaque as it can visualize and localize the position of the lesions which would not be possible by any other means.

Corona virus disease officially called as COVID-19, declared a “pandemic” by the World Health Organization; became a major public health problem causing worldwide morbidity and mortality, despite various control measures. Extraordinary measures are taken universally to fight the spread of the ongoing outbreak. In such a scenario, people’s adherence to preventive measures is largely influenced by their knowledge and perception of the disease. Since dental care professionals are having high chances of infectivity, which in turn has serious implications, it is essential that the auxiliary dental staff must be educated, empowered and provided appropriate and relevant knowledge of the disease.

To assess the level of awareness regarding COVID-19 among auxiliary dental staff in a Tertiary Dental Care Centre in Kerala.

A cross sectional survey was conducted among all the auxillary staff in a tertiary dental care centre by an online questionnaire through google forms. Details regarding demographic data, knowledge about the spread, symptoms, diagnosis, prevention and safety practices related to COVID-19 were obtained after getting an online informed consent. Descriptive statistics and Chi square test were done. Associations and differences were considered significant when the p value was less than 0.05.

The initial sample size was 50. Forty two participants completed the study. Out of the participants 36% (n=15) were below 40 years and were males. About 40.5% (n=17) had experience less than 5 years. Around 69% (n=23) of the participants had good knowledge regarding COVID 19. Statistically significant results were seen with mode of transmission of Covid 19 and age of the respondents (p value=.006);current treatment of Covid 19 and years of experience of the respondents (p value=.011).

The study concluded that there is overall good awareness level among the participants of the study.

: An emergency can be encountered anytime and anywhere. Minimal knowledge about medical emergency and their etiology, primary protocol for management must be known to avoid potential consequences. Hence, the present study was undertaken to compare the knowledge, and ability to handle the medical emergencies among the dental students.

A cross-sectional survey was conducted among 100 randomly selected dental students (post-graduate students and interns) comprising of two groups of students those who had underwent training and those who did not. The data obtained was analyzed using the SPSS for windows version 22.0 released 2013.

Independent chi square test was used for comparison of responses and independent student t-test was used for the comparison of mean scores. The significance level was set at p<0.001.

: The average mean knowledge and ability score was 68% & 61.4% respectively among the participants. On further comparison of mean knowledge & ability scores between the participants with & without basic life support training, participants with BLS training showed better knowledge than those without training and the difference was statistically significant between the two groups (p<0.001%).

The study found deficiencies in the knowledge and ability of untrained graduates to deal with medical emergencies as compared to trained.

Published: October 2021

Cystic lesions of the jaw are a common occurrence. We present a case of a large unilocular cystic lesion in maxilla associated with an impacted tooth, impinging on the nasal floor. The uniqueness of the case is the high probability of a dual pathology; a cystic pathology associated with the impacted tooth (likely dentigerous cyst) and a large radicular cyst involving the apices of teeth from 21 to 26. The patient presented with a rare finding of a palatal swelling rather than a buccal swelling associated with cystic lesions involving maxillary posterior teeth. Enucleation of the cyst and extraction of the impacted tooth were performed, no other teeth were extracted. The report describes the treatment and follow up of the patient.

The article presents the results of the electromagnetic activation of petroleum feed in the vortex layer apparatus. It is shown that under the electromagnetic influence, there is a significant increase in the proportion of straight-run gasoline fraction distillate, as well as a change in the physicochemical parameters of the light fractions obtained as a result of the cavitation effect and the low-temperature cracking. It has been established that the processes of wave action on oil occurring in the electromagnetic field zone lead to a change in the individual and group hydrocarbon composition of the distillates obtained. The gasoline fraction produced from activated petroleum, due to an increase in the proportion of aromatic compounds, has a high octane number compared to the original straight-run fraction and low content of alkenes, which allows us to recommend its use as a high-octane component of motor fuels in the compounding and production of commercial gasoline.

Background: Rapid expansion in population increased the global food demand. To meet this surge in demand for food and to ensure food and nutritional security addition of pulses in the cropping system is a visible alternative. Pulses intensifies cropping intensity, enhances health and fertility status of the soil and acts as a good source of dietary protein etc. However, due to a wide gap between the potential and actual yield of pulses in rainfed areas. Hence, identification and adoption of best management practices has become a pre-requisite. The present study was undertaken as the information available on foliar nutrition and different crop geometries on performance of different blackgram genotypes in rainfed condition is meagre. Methods: In this investigation conducted during kharif season of 2018 at Advanced Centre for Rainfed Agriculture, SKUAST-Jammu, Rakh Dhiansar. The experiment was laid out in factorial randomized block design with 3 factors and 3 replications. The factor-1 consisted of three blackgram cultivars (Uttara, PU-31 and Mash-114), factor 2 consisted of two crop geometries (30×10 cm and 45×10 cm) and factor-3 consisted of three foliar nutrition (Foliar spray of molybdenum as sodium molybdate @ 0.1% at 20 DAS, Foliar spray of 1.5% KCl at flowering and Foliar spray of molybdenum as sodium molybdate @ 0.1% at 20 DAS fb 1.5% KCl at flowering). Result: The results from the present investigation indicated that adoption of Mash-114 at 30×10 cm crop geometry, supplemented with foliar application of molybdenum as sodium molybdate @ 0.1% at 20 DAS fb 1.5% KCl at flowering could be a viable technological proposition under rainfed conditions of Jammu.

Authors: Bharti Pranay , Kamboj M.L.
Published: October 2021

Background: The young calves are the future replacement stock in any farm. Traditionally calves are allowed to suckle their dams while in modern intensive dairy farming calves get separated from the dam. The current study was aimed to find the influence of weaning and natural suckling on the colostrum, milk and dry matter intake growth performance of Sahiwal calves. Methods: Twelve newborn Sahiwal calves were selected and divided into 2 groups, one group was weaned from their dams immediately after birth (weaned group) and another allowed to suckle their dam (suckled group). The parameters were taken daily for colostrum intake, weekly for milk intake and fortnightly for total dry matter intake (from milk, green fodder and concentrate), body weight and average body weight gain. Result: The mean daily colostrum intake during the first 3 feedings were significantly (P less than 0.05) lower in weaned calves as compared to suckled calves. The mean daily milk intake was significantly (P less than 0.05) higher in suckled (3.37 kg/day) as compared to weaned (2.80 kg/day) calves whereas average total dry matter intake did not differ between weaned and suckled calves. The mean final body weights at 12th fortnight was only numerically higher in suckled group of calves as compared to weaned group of calves while the overall average daily gain (ADG) was significantly (P less than 0.01) higher in case of suckled calves (0.419±0.012 kg/day) than weaned (0.377±0.009) group of Sahiwal calves. It was concluded that the colostrum and milk intake performance as well as the final body weight and average daily body weight gain was improved in naturally suckled Sahiwal calves as compared to weaned calves.
