The Evolution of the Regional Development Policies
Authors: Popescu Constanţa , Ristea Ana Lucia , Popescu Constantin
Published: October 2016

Kuklinski (Kuklinski A. 1987), realized, from an epistemological perspective, a history of the international and interdisciplinary progress in matters of regional policy.

According to the authors’ conception, an international scientific movement in the domain of regional studies refers to: the examination of the regional studies carried out in different countries to identify the diversity of ideological and intellectual attitudes, the techniques and the motivations.

Today this phenomenon must be considered from a new perspective in the framework of a global analysis of the different scientific schools which perceive regional studies in particular and original ways.

A scientific school can be defined as all the activities of a well-organized team, capable of producing, in the course of a long period, a series of relatively important and diversified innovations in three domains:

a)

theory and research methods;

b)

empirical knowledge of the existing reality;

c)

creation of tools and policies in order to transform this reality according to the development goals accepted by a determined epoch and in a determined region.

The main feature of a scientific school is represented by its capacity to innovate a series of theoretical and empirical studies (Kuklinski A. 1987).

Published: October 2016

Considering the technological and economic changes over the years, we have found that we are currently witnessing an increase in the information system in the future. In fact, it is found that the information domain has known divergence over time, significantly in practice. Therefore, it is not surprising that the academic recommendations are rarely adopted by practitioners in response to this problem, so it is suggested in the future a turn towards the practice.
Atypical ubiquitination of proteins
Authors: Buneeva O.A. , Medvedev A.E.
Published: October 2016

Ubiquitination is a type of posttranslational modification of intracellular proteins characterized by covalent attachment of one (monoubiquitination) or several (polyubiquitination) of ubiquitin molecules to target proteins. In the case of polyubiquitination, linear or branched polyubiquitin chains are formed. Their formation involves various lysine residues of monomeric ubiquitin. The best studied is Lys48-polyubiquitination, which targets proteins for proteasomal degradation. In this review we have considered examples of so-called atypical polyubiquitination, which mainly involves other lysine residues (Lys6, Lys11, Lys27, Lys29, Lys33, Lys63) and also N-terminal methionine. The considered examples convincingly demonstrate that polyubiquitination of proteins not necessarily targets proteins for their proteolytic degradation in proteasomes. Atypically polyubiquitinated proteins are involved in regulation of various processes and altered polyubiquitination of certain proteins is crucial for development of serious diseases.
The effect of melaxen administration on the tissue oxidative status in rats with brain ischemia/reperfusion
Authors: Popova T.N. , Safonova O.A. , Stolyarova A.O.
Published: October 2016

Melaxen administration to rats with brain ischemia/reperfusion was accompanied by a decrease of the lactate level (an organ ischemia marker), biochemiluminescence parameters characterizing the intensity of free radical processes and total antioxidant activity, the content of lipid peroxidation products, activity of superoxide dismutase and catalase, as compared with the values determined in rats with induced brain ischemia/reperfusion. Activity of aconitate hydratase, a sensitive target of free radicals action, and the citrate level in the brain and blood serum of melaxen-treated animals changed towards control values of intact animals. It is assumed that the effect of melaxen is associated with implementation of the antioxidant and protective properties of melatonin, the melaxen constituent, under conditions of post-ischemic reperfusion injury, accompanied by oxidative stress development.

Optimal conditions for obtaining phosphatidylholine (PC) liposomes with lipoic acid (LA) are chosen that lead to the formation of nanoparticles with a size of 175¸284 nm with efficiency (extent) of inclusion of LA in liposomes equal 85% and characterized by a slow release of substance from the nanoparticles. The effect of “empty” liposomes and liposomal form of LA on platelet aggregation induced by arachidonic acid (AA) is established. It is found that liposomes with LА inhibit platelet aggregation, caused by AА, to 80%. In addition, it is shown that “empty” liposomes slightly (to 30%) suppress platelet aggregation, caused by AА. The amount of TBA-sensitive products in samples of platelet-rich plasma (PRP) incubated with liposomal LA is determined. It is shown that LA in the composition of liposomes retains its antioxidant properties, and the amount of products of lipid peroxidation in platelet-rich plasma decreases in a dose-dependent manner when arachidonic acid is used as an inductor of platelet aggregation. It is assumed that the antiplatelet action of the liposomal form of LА is induced by inhibition of the initiation of lipid peroxidation products caused by exogenous inducer AА. It is supposed that, after additional research, the liposomal form of LA can be considered as a new drug in complex treatment of cerebral ischemia.

The aim of this study was to examine the relationship between serum levels of parameters of the system metalloproteinase (MMP)/inhibitors with severity of infiltrative pulmonary tuberculosis (ITL), changes in examined parameters during the intensive phase treatment (IPT), as well as possibility of their use for prediction of IPT effectiveness, along with acute-phase proteins (AFP). The study included ITL patients which were subdivided into two groups (I and II) with different rates of reparative changes. It was shown that: 1) ITL is characterized by impairements in the system MMP/inhibitors: the levels of MMP-1, -9 increased, MMP-3, -8, TIMP-1 remained at the reference values and a 2-macroglobulin was low. 2) Changes of the parameters of the system MMP/inhibitors were associated with markers of severity and activity of the process: MMP-1, with the presence of destruction and sensitivity of the pathogen (Mycobacterium tuberculosis; MBT) to anti-TB drugs, MMP-9, with the volume of destruction, MMP-8 – with activity of tuberculosis. 3) TIMP-1 and MMP-9 concentrations decreased during treatment in groups with different rates of reparative process, whereas proMMP-1, MMP-3,-8 remained unchanged. 4) Before and after IPT, the level of TIMP-1 was higher in the group of patients with slower rate of reparative processes. 5) After IPT the imbalance in the system MMP/inhibitor preserved thus suggesting continuation of the reparative process. 6) Use of combination of MMP and AFR is more informative in predicting efficacy of IPT.

Three different interlocking intramedullary nails for unstable reverse oblique inter-trochanteric fractures: a bio-mechanical comparative study
Authors: Debnath Ujjwal K. , Maripuri S. Naidu , Subramanian K. N. , Mohanty K.
Published: October 2016

Background: Biomechanical testing, intramedullary devices have proven advantageous over the extramedullary devices in the management of unstable intertrochanteric fractures. Reverse oblique type of intertrochanteric fractures are highly unstable and intramedullary nails are currently the method of internal fixation. The currently available nails seems to provide rotational, axial and angular stability, but biomechanical analysis of the strain pattern in the bone and implant in this fractures are lacking. The aim of this experimental study was to analyse the strain in three different long femoral nail-bone units under physiological loading when implanted in Saw bone model after creating a reverse oblique intertrochanteric fracture.

Methods: A total of 12 sawbones were divided in to 4 equal groups. Group 1 was intact saw bones and were used as controls. Group 2, Group 3 and Group 4 were implanted with Depuy, Stryker and Synthes nails respectively after creating a reverse oblique intertrochanteric fracture. All the four groups were axially loaded with 100 N increments until physiological loads. The strain patterns were measured at the posteromedial cortex and the peak strains were extracted at partial weight bearing i.e. 500 N and full weight bearing physiological loads i.e. 1000 N.

Results: There was no significant difference in peak strains among the groups at partial loads. However at 1000 N loads the peak strain in the DePuy nail-bone unit was significantly high compared to the other two nail-bone units and the controls.

Conclusions: These results question the safety of immediate full weight bearing following surgery when treating the reverse oblique unstable fractures with DePuy intramedullary nails. A period of partial weight bearing following fixation of reverse oblique fractures would be wise when using DePuy nails.
Управленческий кризис и субъективно-технологические предпосылки его преодоления в рамках парадигмы «эффективности»
Authors: Анисимов Олег Сергеевич
Published: October 2016

Мировой кризис, очевидность которого не требует доказательства, и его острые формы демонстрируются в растущем противостоянии «Запад – Россия», а в ином выражении «Запад – Восток», непосредственно связан и с попытками России выйти из той роли, которая была вменена ей после краха СССР, победы «Запада» в «холодной войне», вернуть себе свою идентичность, самостоятельность, полноценное развитие. В этих условиях особую роль играет аналитика и ее качество, аналитические технологии, подготавливающие не только «объективный» взгляд на происходящее, но и возможность разработки неслучайных решений стратегического уровня.

Published: October 2016

Основное внимание авторы статьи уделяют проблеме честности как нравственной ценности профессионала. Показана взаимосвязь уровня честности как нормативной ценности со стратегией поведения в ситуации морально-нравственного конфликта в профессиональной деятельности. Честность, как нравственная ценность профессионала, выступает ориентиром в ситуации социального взаимодействия, но не оказывает решающего влияния на выбор «честной» стратегии поведения. Исследование авторов показывает, что профиль профессионального образования влияет на предпочтение честного выбора в ситуации морально-нравственной дилеммы в профессиональной деятельности.

Selected small molecules as inductors of pluripotent stem cells
Authors: Baranek Małgorzata , Markiewicz Wojciech T , Barciszewski Jan
Published: October 2016

The general idea of regenerative medicine is to fix or replace tissues or organs with alive and patient-specific implants. Pluripotent stem cells are capable of indefinite self-renewal and differentiation into all cell types of body with origin from the three germ layers of the developing embryo, therefore they have a potential to play a substantial role in regenerative medicine. Easily accessible source of induced pluripotent stem cells may allow obtaining and culturing tissues in vitro. Many improvements in the methods leading to obtain such cells have been made by various research groups in order to limit immunogenicity and tumorigenesis, increase efficiency and accelerate kinetics. One of the approaches affecting pluripotency is usage of small molecule compounds including RNA-derivatives – nucleosides analogues. It would be great to assess general character of such molecules and reveal their new derivatives or modifications to improve induced pluripotent stem cells (iPSCs) reprogramming efficiency. Understanding the epigenetic changes during cellular reprogramming will extend understanding of stem cell biology and lead to potential therapeutic approaches. In this digest of compounds found in literature as proven or putative inductors of cells’ reprogramming to pluripotency there are compounds that may substitute for transgenic nucleic acids delivery in order to improve time and efficiency of reprogramming. Nucleic acids’ derivatives or modifications of particular atoms or substitutes influence modulating activities of small molecules, especially their inhibiting activity.  Due to dosage-dependent effect of small molecules influence on genes, their application concentration needs to be strictly determined.
A Novel Rat Model of Polymicrobial Peri‐Implantitis: A Preliminary Study
Authors: Koutouzis Theofilos , Eastman Christie , Chukkapalli Sasanka , Larjava Hannu , Kesavalu Lakshmyya
Published: October 2016

Background: Peri‐implantitis is a complex polymicrobial biofilm‐induced inflammatory osteolytic gingival infection that results in orofacial implant failures. To the best knowledge of the authors, there are no preclinical in vivo studies in implant dentistry that have investigated the inflammatory response to known microbial biofilms observed in humans. The aim of this study is to develop a novel peri‐implant rat model using an established model of polymicrobial periodontitis.

Methods: Wistar rats were used for the study of experimental peri‐implantitis. One month after extraction of maxillary first molars, a titanium mini‐implant was inserted. Two months after implant healing, implants were uncovered, and abutment fixing was done using cyanoacrylate to prevent abutment loosening. Rats were separated into two groups (group A: polymicrobial‐infected and group B: sham‐infected). One week after healing of abutments, rats were infected with Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia for 12 weeks. Bacterial colonization, bone resorption, and implant inflammation were evaluated by polymerase chain reaction (PCR), microcomputed tomography, and histology, respectively.

Results: Three rats with four implants in the infection group and two rats with three implants in the sham‐infection group were analyzed. PCR analysis revealed presence of bacterial genomic DNA, and infection elicited significant immunoglobulin (Ig)G and IgM antibody responses, indicating bacterial colonization/infection around implants. Infection induced an enhanced mean distance from implant platform to the first bone‐to‐implant contact, extensive peri‐implantitis with advanced bone resorption, and extensive inflammation with granulation tissue and polymorphonuclear leukocytes.

Conclusions: To the best knowledge of the authors, this is the first study to develop a novel rat model of polymicrobial peri‐implantitis. With modifications to improve implant retention it could offer significant advantages for studies of initiation and progression of peri‐implantitis.
Integration of omics and system biology approaches to study grapevine (Vitis vinifera L.) response to salt stress: a perspective for functional genomics - A review
Authors: Daldoul Samia , Ben Amar Anis , Guillaumie Sabine , Mliki Ahmed
Published: October 2016

The ability of plants to modify their behavior appropriately in response to salt stress is a major factor in their adaptation to this specific constraint. To date, environmental constraints, including salinity, become more and more unfavorable especially for glycophytes such as grapevines. Salt tolerance is a complex physiological and multigenic trait. Studying the functional networks of transcriptome, proteome and metabolome of grapevine plants subjected to salinity may help to identify candidate genes associated with salt tolerance mechanisms. Thus, the integration of omics tools (i.e., genomics, proteomics and metabolomics) with physiological approaches allows better understanding of the grapevine plant response and developing efficient markerassisted selection strategies in order to generate salt stress resistant grapevine varieties. In this review, research progress in grapevine responses to salt stress is discussed, highlighting the importance of the system biology approach for identifying molecular regulatory networks leading to a better adaptation ability of grapevine to salt stress.

Metode pembelajaran adalah cara yang digunakan guru dalam mengadakan interaksi antara guru dengan siswa. Setiap metode pembelajaran memiliki kelebihan dan kelemahan masing-masing. Oleh karena itu, dalam praktek pembelajaran mustahil menggunakan satu metode saja. Kombinasi (kolaborasi) penggunaan beberapa metode merupakan keharusan dalam praktek pembelajaran. Terkait dengan parktek pembelajaran di kelas, peneliti selaku guru kelas mengalami permasalahan dalam pelajaran IPS mendeskripsikan materi “Perkembangan Teknologi” pada siswa kelas IVB yang berdampak pada rendahnya prestasi siswa. Penyebab kegagalan tersebut yaitu metode yang digunakan kurang tepat dan kurangnya motivasi siswa dalam mendiskripsikan persoalan. Oleh karena itu peneliti mencoba menggunakan kolaborasi metode ceramah, diskusi dan latihan. Berdasarkan hasil penelitian tindakan kelas yang dilakukan terhadap siswa kelas IVB SDN Pinggir Papas 1 selama dua siklus, kolaborasi metode ceramah, diskusi dan latihan dapat meningktkan prestasi belajar siswa. Untuk prestasi belajar siswa yang tuntas secara indvidu mulai dari siklus I sebanyak 22 siswa (73%) dengan nilai rata-rata 74, pada siklus II bertambah menjadi 27 orang (90%) dengan nilai rata-rata 87. Sedangkan untuk  aktivitas belajar siswa pada siklus I mendapat penilaian 60% meningkat menjadi 93,3% pada siklus II, maka dapat dikatakan bahwa pada siklus II ini perbaikan pembelajaran yang dilakukan guru dengan menggunakan kolaborasi metode ceramah, diskusi dan latihan telah berhasil menjadikan siswa aktif dalam mengikuti kegiatan pembelajaran.

IMPROVEMENT OF SEEDLING ESTABLISHMENT OF WET SEEDED RICE USING GA3 AND IBA AS SEED TREATMENT
Authors: Wahyuni Sri , Sinniah Uma R. , Yusop Mohd. Khanif , Amarthalingam Rajan
Published: October 2016

Direct seeding has some advantages compared to transplanting system in rice, however there are some constraints need to be addressed. One  constraint generally faced in the wet seeded rice is poor stand  establishment. The experiment was conducted to improve seedling  establishment by using selected growth regulators. Seeds of four rice  cultivars, i.e. Memberamo, Widas, MR 84, and MR 219 were treated with  GA3 (gibberellic acid-3) of 25, 50, and 100 mg 1-1, and IBA (indole-3  butyric acid) of 10, 20, and 40 mg l-1. Results showed that cultivar  response to GA3 was similar in all parameters observed, however the response of cultivars to IBA was different at the initial stage. In Indonesian cultivars (Memberamo and Widas), shoot length of IBA treated seedlings was comparable to the control, but the IBA treated seedlings of  Malaysian cultivars (MR 84 and MR 219) had slightly shorter shoots   compared to the control. GA3 as seed treatment induced favorable early emergence and shoot growth in the initial stage, but the shoots were  etiolated and resulted in susceptible to lodging even in the vegetative  stage. In comparison, exogenous application of IBA resulted in high number of adventitious roots contributing towards better establishment of seedling with broader and greener leaves. The growth regulator was lost its  effect by 2 or 3 weeks after sowing. All IBA concentrations also did not  show any significant differences on growth parameters or have any detrimental effect on grain yield in all cultivar tested. IBA 10 mg l-1 was  sufficient in providing the required improvement in the rice seedlings.

Rice plants have been reported to affect methane (CH4) emission from rice fields. The objectives of this study were to determine the effect of rice cultivars on CH4 emission from flooded rice and to develop crop management strategies with low emitting rice cultivars while sustaining high yield. The four rice cultivars studied were Memberamo, Cisadane, IR64, and Way Apoburu. The CH4 emissions were determined in the wet season of 2001/2002 (November-February) using an automated closed chamber technique in an irrigated field condition. Farmyard manure at the rate of 5 t ha-1 was given to the plots to ensure carbon was not limited. Root weight, root length, biomass, and number of tillers were determined at 17, 36, and 57 days after transplanting (DAT). The results showed that the mean CH4 emission was highest in the plot planted with Cisadane (94.8 kg CH4 ha-1), and the lowest with IR64 (37.7 kg CH4 ha-1). The plots treated with emberamo and Way Apoburu resulted an intermediate CH4 emission at the average of 61.1 and 58.9 kg CH4 ha-1, respectively. There was no significant difference in yield between the cultivars tested. The yield of Memberamo, Cisadane, IR64, and Way Apoburu were 5.882, 5.764, 5.873 and 6.065 t ha-1, respectively. Statistical analysis showed that there were no significant differences in the root weight and root length among cultivars. However, Cisadane gave the highest dry matter weight (222 g hill-1) at 57 DAT compared to the other cultivars (175-190 g hill-1). Plant tillers did not show significant differences between the cultivars. Regression analysis showed that CH4 flux was significantly related with root weight, root length, aboveground biomass, and number of plant tillers. This finding shows that the use of selected cultivars, such as IR64, can potentially lower CH4 emission without scarifying yield.

Sago starch has potential as source of flour for noodle. However, noodle made of sago starch has only been limitedly utilized due to the absence of gluten and lack of desired functional properties. Heat moisture treatment (HMT) is a promising technique for improving quality of sago noodle. The objectives of the present work were to study the effect of HMT of sago starch on its noodle quality. Four different origins of sago starch, i.e. Tuni, Ihur, Molat, and Pancasan, were treated with HMT method. HMT was performed by exposing the starch to high temperature (110oC for 16 hours) at moisture content of 25%. Sago starch was then processed into noodle. It was prepared by mixing the sago starch with binder (completely gelatinized starch and additive) into dough. The dough was pressed manually through a container with holes in the base. Noodles strains were steamed for 2 minutes and dried at 50oC in a convection drier. As the control, non-HMT sago starch was used and evaluated. Parameters evaluated were starch properties, physical strength, and cooking and sensory quality of the noodles. Analyses of variance was subjected to all parameters. Research results showed that the starch exposed to HMT changed its pasting profile from initial type A before treated to type B after treated. The noodle quality was also improved. Noodles resulted from starch treated with HMT showed higher firmness and elasticity, but they have lower stickiness compared to those of non-HMT. Less cooking loss and rehydration weight were also found, however, HMT increased cooking time of the noodles. HMT on Pancasan sago starch resulted in noodles which were preferred most by panelists. However, consumer testing is recommended to further validate consumers' preferences to the sago starch noodles. The study indicated that sago starch could be potentially used as raw material for noodles to increase the consumption of sago-based food.

Dissolution of phosphate rock (PR) in soils is a primary concern for P in the PR to be available for plant. The dissolution of three PR materials, China (CPR), Ciamis (IPR) and Gafsa (GPR), in eight acid Indonesian soils (pH in water 4.1-5.7) was tested in a closed incubation system. Experiment was conducted in Soil Chemical Laboratory, Universiti Putra Malaysia and Indonesian Center for Agricultural Land Resources Research and Development from January to April 2002. The dissolution was determined from the increase in either 0.5 M NaOH extractable P (∆P) or 1 M BaCl2-triethanolamine (TEA)-extractable Ca (∆Ca) in soils amended with PR compared with control soil. Dissolution of the IPR was the highest (30-100%) followed by GPR (17-69%) and then by CPR (20-54%). The maximum dissolution followed the order: Bogor Ultisols > Bogor Oxisols > Subang Inceptisols > Bogor Inceptisols > Sukabumi Oxisols > Lebak Ultisols > Sukabumi Inceptisols > Lampung Ultisols. PR dissolution indicated a positive correlation with P retention capacity. The results implied that the extent of PR dissolution for the three PR sources (China, Indonesia and Tunisia) increased with increasing P retention capacity of the soils. PR dissolution can be based on a calibration curve of ∆Ca meaning that if ∆P is high then the amount of PR dissolution measured by ∆Ca in PR materials is also high.
BIOMASS PRODUCTION AND FORMULATION OF Bacillus subtilis FOR BIOLOGICAL CONTROL
Authors: Muis Amran
Published: October 2016

Bacillus subtilis is a widespread bacterium found in soil, water, and air. It controls the growth of certain harmful bacteria and fungi, presumably by competing for nutrients, growth sites on plants, and by directly colonizing and attaching to fungal pathogens. When applied to seeds, it colonizes the developing root system of the plants and continues to live on the root system and provides protection throughout the growing season. The study on biomass production and formulation of B. subtilis for biological control was conducted in the laboratory of Department of Plant Pathology, College of Agriculture, University of the Philippines Los Baños (UPLB-CA), College, Laguna from May to July 2005. The objective of the study was to determine the optimum pH and a good carbon source for biomass production of B. subtilis and to develop a seed treatment formulation of B. subtilis as biological control agent. Results showed that the optimum pH for growth of B. subtilis was pH 6 (1.85 x 109 cfu/ml). In laboratory tests for biomass production using cassava flour, corn flour, rice flour, and brown sugar as carbon sources, it grew best in brown sugar plus yeast extract medium (6.8 x 108 cfu ml-1 in sterile distilled water and 7.8 x 108 cfu ml-1 in coconut water). In test for bacterial biomass carriers, talc proved to be the best in terms of number of bacteria recovered from the seeds (3.98 x 105 cfu seed-1).

Physiological status of chrysanthemum cuttings during rooting process highly influences plant growth and flower production. Amongst other aspects, rooting capacity of the cuttings is the most important. Rooting capacity is influenced by environmental conditions such as growing medium and nutrition. The study was aimed to analyze the effects of different types of media, fertilizer concentration, and frequency of fertilizer application on the rooting capacity of chrysanthemum cuttings. The experiment was conducted at the Segunung Experimental Station of the Indonesian Ornamental Crops Research Institute from February to May 2005. The treatments consisted of four different rooting media, i.e. carbonized rice husk, coco peat, perlite, and mixture of perlite and vermiculite (1:1 v/v); two concentrations of NPK (25:7:7) fertilizers, i.e. 1.75 and 2.5 g 1-l; and four frequencies of fertilizer application, i.e. every 1 day, 2 days, 3 days, and 4 days. The experiment was designed in a completely randomized block with four replications. Parameters observed were rooting capacity and cutting performances such as cutting height, cutting diameter, number of leaves, number of visible roots, and root length at 16 days after planting. The results showed that chrysanthemum cuttings rooted in carbonized rice husk had better performance than those rooted in coco peat, vermiculite, and mixture of perlite + vermiculite. Higher concentration of fertilizer solution up to 2.5 g l-1 also gave significant effect on the root formation and further root growth of cuttings. However, the rooting capacity of cuttings was not affected by the frequency of fertilizer application. This study implied that carbonized rice husk growing medium supplemented with NPK (2.5 g l-l) every 4 days during rooting period is the choice for traditional chrysanthemum growers to increase the perform-ance and quality of the cut flowers.
ASSESSING GLOBAL CLIMATE VARIABILITY UNDER COLDEST AND WARMEST PERIODS AT DIFFERENT LATITUDINAL REGIONS

Effect of climate change on water balance will play a key role in the biosphere system. To study the global climate change impact on water balance during 95-year period (1901-1995), long-term grid climatic data including global mean monthly temperature and precipitation at 0.5 x 0.5 degree resolution were analysed. The trend and variation of climate change, the time series of monthly air temperature and precipitation data were aggregated into annual arithmetic means for two extreme periods (1901-1920 and 1990-1995). The potential evapotranspiration (Eo) was calculated using Thornthwaite method.
The changes in mean annual value were obtained by subtracting the maximum period data from 1990 to 1995 (Max) with the minimum period data from 1901 to 1920 (Min). The results revealed that over 95-year period, mean global air temperature increased by 0.57oC. The temperature increase varied greatly in Asia, with more than 3.0oC, especially at 45-70oN, as well over the northern part of America (60-65oN) and Europe (55- 75oN). In low latitude across Asia, Africa, and South America, the variation was less than 1.5oC. In 80-85ºN region, the variation was relatively small and at higher latitudes it increased
significantly. Precipitation varied temporally and spatially. In the 40-45ºN and 40-45ºS regions, increasing precipitation of more than 100 mm occurred during the June-August and
September-November, especially in the northern hemisphere. The Eo increase of 2000 mm during 95 years occurred in the tropical northern America, middle Africa, and South-East Asia. A grid in Central Java of Indonesia showed that the Eo increase of 2500 mm during 95 years resulted in the decrease of growing period by 100 days. In coping with climate change, adjustment of cropping calendar is imperative.
